Waiting for "IOTA TIME " (an era where IOTA defines nearly everything in terms of the block-chain world)

IOTA funds are public: https://thetangle.org/address/IDNAFP9FWWKYGNDMKGJWZD9GATGRPTJYTYHLKFNDEQSISPSETLZQOSPGOHC99LMPXDEHSH9XYHNVOLUBBQPCEGHYK9 But they have probably other sources of income, like funding by government etc. And maybe also other IOTA funds on other addresses. I don't know.
Balance: 59.68 Ti

I wonder how many times an out of context 2 year old private DM has to be addressed. At the time IOTA was approaching stagnation due to the actions of primarily CFB**, thus since we both started Jinn together which lead to IOTA,** I tried repeatedly to talk sense into him. I.E. "If you are going to torpedo all progress, let's just sell it all and start from scratch, fuck it" It's a figure of speech, while trying to talk sense into someone who insists that 1 + 1 = 3.59 My tax records show when I last sold iotas. February of 2018. Now stop reading into private DMs, especially ones taken out of context and especially those leaked by someone who's proclaimed he is going to ruin IOTA and my life. You need to go back to school if you think there is anything to 'speculate' on there.

u/unsy we will release the condensed version of them once we want to. Just because you so desperately desire them for whatever reason doesn't make us do it faster. Being in this space for so fucking long, last thing I want is to attempt to act in good faith again and then be screwed over by those trying to misconstrue reality and spread lies. We've been at that for too long. Once they are fully ready, and we have them in a format we like, we will publish them.


dom어제 오후 4:16
Our objective of the finance / legal department is to become one of the most trustworthy / transparent organizations in this space. Which is why we're setting up new and stricter policies in general


dom어제 오후 4:18
quite frankly, with everything that has happened up until now, I would certainly say that we are one of the most transparent organization (if we wanted it or not) u/unsy


dom어제 오후 4:21
u/unsy I am not worried about it. If we have problems, we always solve them - I think we've proven that by now. And as it stands right now with our current funding + our strategy, we are in good hands

IMO the community has matured a lot, we have community and certified developers working with the IF in the X-Teams, there are new people coming in with direct interest in the tech (yeah, also spec is still popular) and from the chats that I've had, there are devs waiting for the breaking changes of Chrysalis P2, before starting to develop again.. But that's my assessment..


Jelle Millenaar [IF]어제 오후 9:15
Well, I can say the DID developments are going smooth. Starting publishing the first DIDs to the Tangle ;D

This is the perfect time to loose faith in the IOTA Foundations capability to deliver, especially after the network just received a major update with many improvements. Its just crypto being crypto,

Yeh we'll go through it. This is the usual game...


Dominik Schiener
There is more tech maturity, more adoption and more progress than ever. We are one of the only projects which gets funding from government grants and corporations. Stop the attention grabbing headlines and get your sources right.


Long field
You can track their iota address, and I can tell they didn't sell any iota tokens in last two months


HusQy
IOTA is like a large decentralized network cable that connects any number of nodes with each other and that enables data and values ​​to be exchanged with one another, whereby the data is protected against manipulation and the value transactions against double spends. Thereon ...

... you can run any decentralized application (we call this layer) - e.g. a blockchain that stores certain data for as long as you want and limits the amount of data to be saved via fees like Bitcoin. Each of these uses inherit ...

... your security from the basic protocol and can specifically only save the data that is relevant for you (also decentralized). To say that IOTA is not a DLT is in principle not that wrong - it is a platform for DLTs and therefore much more powerful than all ...

... existing DLTs because it is much more flexible. For example, you can run Hashgraph in IOTA, or Bitcoin or whatever. And IOTA is the token that connects the entire ecosystem. This is of course "not yet" the case, but Chrysalis Part 2 is the first step.​


HusQy
@blocktrainerperhaps this explanation will enable you to understand where the journey is going. If a decentralized data storage is required, then you can build it with IOTA and it then has exactly the same properties in terms of permanent storage as Bitcoin.


Block trainer
We can also get a little more technical. The way you describe it, it sounds like an interoperability layer ... something like that here, which then equates to a polkadot etc.
📷

HusQy
In principle yes, only that it doesn't connect Bitcoin and ETH but "IOTA Smart Contracts" with "IOTA Storage" etc. It is not there to connect other projects but to offer the same as other projects, only faster and cheaper.

-------------------------------------------------------------------------------

Bitcoin Coach
And in 5 years there will be a completely new project, which then claims to be better than IOTA. And then should all the infrastructure be thrown overboard and the partners simply change the DLT?


HusQy
This is how technology works. It makes no sense to run the Internet on the basis of 64k modems just because many people have one at home. The change does not take place overnight but creeping and if you look at the BTC Dominance you can see that too.

Ultimately, everything will switch to the best technology and we'll see which that is :)


Block trainer
The "best" must also be defined. What are the classes to master?


HusQy
All classes. If there is a technology that can represent even one aspect better, then it is not yet good enough. Blockchain, for example, is a "degenerate" DAG with only one reference. The goal is that IOTA can also use blockchains if the use case requires it.


HusQy
The future is not "either DAG or blockchain" but both seamlessly linked within the same ecosystem. IOTA smart contracts use a blockchain, for example, but a separate chain for each smart contract and the blockchain is within the tangle.

Block trainer
According to the new definition, they are no longer saved ... A doublespent could change the reference retrospectively.


HusQy
That's not quite true. The tangle itself contains all information for all eternity and you cannot remove any information. Once the data has reached a certain age, it is no longer stored by every node in the network. But you can still ...

... still prove what happened in the part of the tangle that was "forgotten" by the nodes after a certain time. Now there are two ways to keep this evidence: 1. You save the evidence personally and can present it at any time. 2. Man ...​​

... writes a plug-in for the node, which monitors the Tangle for information of a certain type and keeps a copy of all car purchase-related data forever (or for at least 30 years, for example). All dealerships could then install this plugin and ...

... jointly store this data decentrally in order to query the information if necessary. However, you would only selectively save the data that interests you. The evidence they produce can still be verified by any node on the network.​​

If the server of a car dealership fails, it can download the data again from one of the other dealerships. Quasi like an application-related private blockchain which is secured by the Tangle. It is also conceivable that there are service providers for this ...

----------------------------------------------------------------------------------


HusQy
Data is only kept immutable. How do you intend to execute a token transaction over pure data? I'm simply sending the following two data transactions at the same time: 1. I'm sending $ 100 from address A to address B. 2. I'm sending $ 100 from address A to address C.


HusQy
In order to determine which transaction is successful / came first, you need consensus. Data transactions do not allow token transfer.


Block trainer
Why doesn't that allow token transfer? I can simply use it to sign my values. The question is about the meaning of the token. I can also sign that I have transferred € 10 for the petrol station. Or I transmit the proof via curled BTC ...


HusQy
Did I just describe you can publish two conflicting data transactions and no one knows which is the correct one: P


Block trainer
Unless you agree on a consensus. Time stamp + BTC (locked) in hash = value transmitted ... What else is the IOTA token for?


HusQy
Whether information is correct can only be seen in the context. Take a look at the difference between "data" and "information". For example, you can claim that you locked Bitcoin even though it didn't.


Block trainer
I may need a proof of this. See how, for example, BTC is unlocked in liquid or in the LN. The IOTA data layer is extremely similar to the principle of Lightning. Accordingly, the sending of tokens would be possible here, which means that I see the use case of the IOTA coin at risk


HusQy
Such a proof is impossible. The reason why this works with LN nodes is because LN nodes are Bitcoin nodes that know what is happening in the Bitcoin network and have "information" and not just "data": P What you are describing is technically impossible.


Block trainer
Data = information What can the LN not, what IOTA can sometimes?


HusQy
That's not rubbish. There is a huge difference between data and information, and inter-chain transactions are not possible because of that very difference. LN won't work - there are too many game theory problems: P​

Dominik Schiener
As an innovation leader in Europe, I certainly say we deserve to get grants. There is a below 7% success chance usually. And yes, everything is fully audited (by externals ofc), showing clearly how and that the money was used in achieving the milestones of the grant.

[OWL WATCH] Waiting for "IOTA TIME" 20; Hans's re-defined directions for DLT

Disclaimer: This is my editing, so there could be some misunderstandings...
--------------------------------------------
wellwho오늘 오후 4:50
u/Ben Royce****how far is society2 from having something clickable powered by IOTA?
Ben Royce오늘 오후 4:51
demo of basic tech late sep/ early oct. MVP early 2021
---------------------------------------------------
HusQy
Colored coins are the most misunderstood upcoming feature of the IOTA protocol. A lot of people see them just as a competitor to ERC-20 tokens on ETH and therefore a way of tokenizing things on IOTA, but they are much more important because they enable "consensus on data".
Bob
All this stuff already works on neblio but decentralized and scaling to 3500 tps
HusQy
Neblio has 8 mb blocks with 30 seconds blocktime. This is a throughput of 8 mb / 30 seconds = 267 kb per second. Transactions are 401+ bytes which means that throughput is 267 kb / 401 bytes = 665 TPS. IOTA is faster, feeless and will get even faster with the next update ...
-----------------------------------------------------------------------------
HusQy
Which DLT would be more secure? One that is collaboratively validated by the economic actors of the world (coporations, companies, foundations, states, people) or one that is validated by an anonymous group of wealthy crypto holders?
HusQy
The problem with current DLTs is that we use protection mechanisms like Proof of Work and Proof of Stake that are inherently hard to shard. The more shards you have, the more you have to distribute your hashing power and your stake and the less secure the system becomes.
HusQy
Real world identities (i.e. all the big economic actors) however could shard into as many shards as necessary without making the system less secure. Todays DLTs waste trust in the same way as PoW wastes energy.
HusQy
Is a secure money worth anything if you can't trust the economic actors that you would buy stuff from? If you buy a car from Volkswagen and they just beat you up and throw you out of the shop after you payed then a secure money won't be useful either :P
HusQy
**I believe that if you want to make DLT work and be successful then we need to ultimately incorporate things like trust in entities into the technology.**Examples likes wirecard show that trusting a single company is problematic but trusting the economy as a whole should be at ...
**... least as secure as todays DLTs.**And as soon as you add sharding it will be orders of magnitude more secure. DLT has failed to deliver because people have tried to build a system in vacuum that completely ignores things that already exist and that you can leverage on.
----------------------------------------------------------------------------------
HusQy
Blockchain is a bit like people sitting in a room, trying to communicate through BINGO sheets. While they talk, they write down some of the things that have been said and as soon as one screams BINGO! he hands around his sheet to inform everybody about what has been said.
HusQy
If you think that this is the most efficient form of communication for people sitting in the same room and the answer to scalability is to make bigger BINGO sheets or to allow people to solve the puzzle faster then you will most probably never understand what IOTA is working on.
--------------------------------------------------------------------------------
HusQy
**Blockchain does not work with too many equally weighted validators.****If 400 validators produce a validating statement (block) at the same time then only one can survive as part of a longest chain.**IOTA is all about collaborative validation.
**Another problem of blockchain is that every transaction gets sent twice through the network. Once from the nodes to the miners and a 2nd time from the miners as part of a block.**Blockchain will therefore always only be able to use 50% of the network throughput.
And****the last problem is that you can not arbitrarily decrease the time between blocks as it breaks down if the time between blocks gets smaller than the average network delay. The idle time between blocks is precious time that could be used for processing transactions.
-----------------------------------------------------------------------------
HusQy
I am not talking about a system with a fixed number of validators but one that is completely open and permissionless where any new company can just spin up a node and take part in the network.
------------------------------------------------------------------------
HusQy
Proof of Work and Proof of Stake are both centralizing sybil-protection mechanism. I don't think that Satoshi wanted 14 mining pools to run the network.
And "economic clustering" was always the "end game" of IOTA.
-----------------------------------------------------------------------------
HusQy
**Using Proof of Stake is not trustless. Proof of Stake means you trust the richest people and hope that they approve your transactions. The rich are getting richer (through your fees) and you are getting more and more dependant on them.**Is that your vision of the future?
----------------------------------------------------------------------------

HusQy
Please read again exactly what I wrote. I have not spoken of introducing governance by large companies, nor have I said that IOTA should be permissioned. We aim for a network with millions or even billions of nodes.

HusQy
That can't work at all with a permissioned ledger - who should then drop off all these devices or authorize them to participate in the network? My key message was the following: Proof of Work and Proof of Stake will always be if you split them up via sharding ...

HusQy
... less secure because you simply need fewer coins or less hash power to have the majority of the votes in a shard. This is not the case with trust in society and the economy. When all companies in the world jointly secure a DLT ...

HusQy
... then these companies could install any number of servers in any number of shards without compromising security, because "trust" does not become less just because they operate several servers. First of all, that is a fact and nothing else.

HusQy
Proof of Work and Proof of Stake are contrary to the assumption of many not "trustless" but follow the maxim: "In the greed of miners we trust!" The basic assumption that the miners do not destroy the system that generates income for them is fundamental here for the ...

HusQy
... security of every DLT. I think a similar assumption would still be correct for the economy as a whole: The companies of the world (and not just the big ones) would not destroy the system with which their customers pay them. In this respect, a system would be ...

HusQy
... which is validated by society and the economy as a whole probably just as "safely" as a system which is validated by a few anonymous miners. Why a small elite of miners should be better validators than any human and ...

HusQy
... local supermarket. Economic relationships in the real world usually form a close-knit network and it doesn't really matter who you follow as long as the majority is honest. I also don't understand your criticism of censorship, because something like that in IOTA ...

HusQy

HusQy
... validators in IOTA do not decide what is included in the ledger, but only decide which of several double spends should be confirmed. Honest transactions are confirmed simply by having other transactions reference them ...

HusQy

HusQy

HusQy
... that would certainly be exciting to discuss in a joint video. But again, that's more of a vision than a specific plan for the immediate future. This would not work with blockchain anyway but IOTA would be compatible so why not think about such things.
-----------------------------------------------------------------------

HusQy
All good my big one :P But actually not that much has changed. There has always been the concept of "economic clustering" which is basically based on similar ideas. We are just now able to implement things like this for the first time.
----------------------------------------------------------------------------------

HusQy
Exactly. It would mean that addresses "cost" something but I would rather pay a few cents than fees for each transaction. And you can "take" this minimum amount with you every time you change to a new address.

HusQy
All good my big one :P But actually not that much has changed. There has always been the concept of "economic clustering" which is basically based on similar ideas. We are just now able to implement things like this for the first time.

Relax오늘 오전 1:17
Btw. Hans (sorry for interrupting this convo) but what make people say that IOTA is going the permissioned way because of your latest tweets? I don't get why some people are now forecasting that... Is it because of missing specs or do they just don't get the whole idea?

Hans Moog [IF]오늘 오전 1:20
its bullshit u/Relaxan identity based system would still be open and permissionless where everybody can choose the actors that they deem trustworthy themselves but thats anyway just sth that would be applicable with more adoption
[오전 1:20]
for now we use mana as a predecessor to an actual reputation system

Sissors오늘 오전 1:31
If everybody has to choose actors they deem trustworthy, is it still permissionless? Probably will become a bit a semantic discussion, but still

Hans Moog [IF]오늘 오전 1:34
Of course its permissionless you can follow your grandma if you want to :p

Sissors오늘 오전 1:36
Well sure you can, but you will need to follow something which has a majority of the voting power in the network. Nice that you follow your grandma, but if others dont, her opinion (or well her nodes opinion) is completely irrelevant

Hans Moog [IF]오늘 오전 1:37
You would ideally follow the people that are trustworthy rather than your local drug dealers yeah

Sissors오늘 오전 1:38
And tbh, sure if you do it like that is easy. If you just make the users responsible for only connection to trustworthy nodes

Hans Moog [IF]오늘 오전 1:38
And if your grandma follows her supermarket and some other people she deems trustworthy then thats fine as well
[오전 1:38]
+ you dont have just 1 actor that you follow

Sissors오늘 오전 1:38
No, you got a large list, since yo uwant to follow those which actually matter. So you jsut download a standard list from the internet

Hans Moog [IF]오늘 오전 1:39
You can do that
[오전 1:39]
Is bitcoin permissionless? Should we both try to become miners?
[오전 1:41]
I mean miners that actually matter and not find a block every 10 trillion years 📷
[오전 1:42]
If you would want to become a validator then you would need to build up trust among other people - but anybody can still run a node and issue transactions unlike in hashgraph where you are not able to run your own nodes(수정됨)
[오전 1:48]
Proof of Stake is also not trustless - it just has a builtin mechanism that downloads the trusted people from the blockchain itself (the richest dudes)

Sissors오늘 오전 1:52
I think most agree it would be perfect if every person had one vote. Which is pr oblematic to implement of course. But I really wonder if the solution is to just let users decide who to trust. At the very least I expect a quite centralized network

Hans Moog [IF]오늘 오전 1:53
of course even a trust based system would to a certain degree be centralized as not every person is equally trustworthy as for example a big cooperation
[오전 1:53]
but I think its gonna be less centralized than PoS or PoW
[오전 1:53]
but anyway its sth for "after coordicide"
[오전 1:54]
there are not enough trusted entities that are using DLT, yet to make such a system work reasonably well
[오전 1:54]
I think the reason why blockchain has not really started to look into these kind of concepts is because blockchain doesnt work with too many equally weighted validators
[오전 1:56]
I believe that DLT is only going to take over the world if it is actually "better" than existing systems and with better I mean cheaper, more secure and faster and PoS and PoW will have a very hard time to deliver that
[오전 1:56]
especially if you consider that its not only going to settle value transfers

Relax오늘 오전 1:57
I like this clear statements, it makes it really clear that DLT is still in its infancy

Hans Moog [IF]오늘 오전 1:57
currently bank transfers are order of magnitude cheaper than BTC or ETH transactions

Hans Moog [IF]오늘 오전 1:57
and we you think that people will adopt it just because its crypto then I think we are mistaken
[오전 1:57]
The tech needs to actually solve a problem
[오전 1:57]
and tbh. currently people use PayPal and other companies to settle their payments
[오전 1:58]
having a group of the top 500 companies run such a service together is already much better(수정됨)
[오전 1:58]
especially if its fast and feeless
[오전 2:02]
and the more people use it, the more decentralized it actually becomes
[오전 2:02]
because you have more trustworthy entities to choose of

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

Allocating banks on Block chain, eliminating processing fee for Global Transactions, Bank operation is transparent, Blockchain AITD public chain achieve the tasks.
Block chain 3.0, innovative upgrading
When we mention Block chain 3.0, I believe everyone is familiar with the concept. Block chain has been praised and promoted heavily by many authoritative medias since it was created; Through the constant effects of information outburst , Block chain 3.0 is becoming a well-known concept like Bitcoin founder Satoshi Nakamoto, but the truth is, people who are able to understand Bitcoin 3.0 concept completely and apply it to actual application are considering as minority group.
So-called Block-Chain 3.0, it is actually the core of valuable internet, we can interpret it as using blockchain tenchnology for the layer structure, building a global distributive accounting system; This account system can not only record the assets transactions in Financial industries, storing data, assets origin;It can also records social networking information, product tracing, self identification verification,product ownership,all valuable information which can be recorded as code status.
This accounting system will cover every aspect of human livelihood, such as birth certification and death certification, marriage certification, education level, financial account, medical process, insurance claim, voting......etc. Most importantly, these data will not controlled by any center organization or capitalist organization, in global distributive accounting system, all data are transparent, tamper prove; Therefore, we can consider block chain 3.0 as a decentralized trust ecosystem kingdom with powerful memory ability。
From Block Chain 1.0 which represented by Bitcoin to Ethereum BlockChain 2.0, then it reaches DeFi which is between Blockchain 2.0 to Blockchain 3.0, Blockchain technology has been updating on the way to our life; Today, Blockchain 3.0 is a necessary process; Throughout the whole Blockchain industries, Blockchain 3.0 project is facing many problems, to achieve highly incorporation between block chain technology and social development, then we need to start innovating and updating based on Blockchain 3.0.
New generation public chain at business level is created because of the current time demand, which is updating the current block chain 3.0 process. Public chain ecosystem is containing 4 competitive industry advantages which belongs to Blockchain, resolving Blockchain 3.0 time problems, connecting throughout the world, to build a Blockchain Trust World which idea comes from Bitcoin founder Satoshi Nakamoto;AITD Blockchain 3.0 is going beyond the tradition meaning of Finance, providing decentralization solution for various industries to achieve" coded business economy", which means to confirm property rights, measurement and storage for each piece of information and word that represented as value, achieving public chain tracing assets,controlling and trading.
Four advantages, infinite applications.
As far as financial world concern, a widely used scenario is Global payment for BlockChain 3.0. In the current project for Blockchain industy,Rayleigh chain is the first chain to do open pay network, we can pay any types of currency on this public chain; Low transaction processing fees and high transaction confirmation speed are exceeding the tradition cross border payment industry; The emergence of Rayleigh chain is making a great contribution for blockchain global applications updating; In many years, Rayleigh business has remained stagnant, the main line ecosystem mode has been criticized for over centralizing, meanwhile, as DeFi industry is rising up, global financial ecosystem has higher standard for decentralized finance, traceability, expanding, perfecting ecosystem problems is coming one after another, Global payment update is imperative.
New generation public chain at business level "AITD Blockchain" is emerging as current time needs". AITD Blockchain is achieving new updated global open payment network, solving the current traceability, expansion, ecosystem problems and making great contribution to facilitate blockchain 3.0;The reason for achieving block chain 3.0 global payment futher goal is contributing to the 4 advantages of public chain ecosystem.
Traceable ecosystem,blockchain traceable system can upload the traceable information completely on the blockchain,enabling safe, permanent stored in decentralized data system; using one object-one code- one coin mode during transactions, which can help corporation build a safe and realible supply chain ecosystem fast, achieving block chain anti-counterfeiting, offline product verification, online traceability imagination;meanwhile, traceable information contains tamper prove, encrypted transactions, permanent storage characteristics, which can protect the authenticity of product supply chains.

Gateway functions: So-called Gateway is real world clearing house and connecting block chain online users to build trust, getting transaction channel; We can consider gateway as a single transaction station on chain, the existance of these stations is for serving on chain users; when they obtain trust from blockchain, then fast cross region payments, liquidation can be achieved,Gate way will provide digitalized assets, cross region payments, cross region transferring, allocation transactions around 10 blockchain application scenarios, improving overall cross region payments or other businesses efficiency, building greater value for global payment system; Gateway will gain economical value when provide services to users on the chain, such as obtaining interests earning, withdrawling processing fee earning, earning matching income, obtaining flow value.
Infinite dilation: The essence of blockchain is distributed information accountbook. In the Bitcoin public chain, to achieve tamper prove , transparency trait for information etc, requiring operation node to download complete block chains record, which is causing operation node to endure significant amount of pressure, turning transaction confirmation process into complicated process; Therefore, Bitcoin ,etherum congestion problems are becoming homostasis status, frequency to handle transactions are becoming the main competitive force for new generated public chain; When it is facing dilation problems, AITD public chain choose to divide nodes into four different types, sharding managment, which is to reduce storage pressure, improving operating efficiency for blocks; The design of sharding node is allowing nodes to attend its own duty, confirming transactions in faster way, alleviating public chain operation pressure, realizing infinite dilation.
Types of nodes
Ø (Collector)
In charge of receiving transaction, transfer to people who completed ranking, processing customer side SDK to start collecting.
Ø (Examiner)
In charge of trade request inspection, executing transaction and maintaining block chain, account structure.
Ø (Reserve)
In charge of inspecting and storing proposal from user side.
Ø (VISA)
In charge of administrating all the certificates(include distribution,withdrawl)
Distributed nodes design is allowing each node doing its job, ensuring transactions at a fast speed. Alleviating the operation pressure on public chain, achieving infinite dilatation.
TIPS unlimited : AITD Blockchain uses modern digital communication, block chain, mobile communication and internet of things techniques, providing convenient efficient deposit ,loan,payments, settlement,transfer ,electric invoices, digital credit , account management, currency exchange, P2Pfinance, investment financing, financial information etc,comprehensive seamless, convenient,safe, high speed decentralized financial services; AITD is revolutionizing traditional banking, becoming the leader for future finance layout , transferring traditional banks from offline to online completely, realizing all the business operations online, building a brand new decentralized banking system, the competitive advantages for decentralized banks are cancelling traditional banks physical branch through blockchain technology, meanwhile, minimising human resources cost for banks, it is concentrating on customer experiences, achieving public sharing, transparency,openess, global interconnected.
Ecosystem kingdom, connecting future
Many people like to call blockchain 3.0 as an ideal period for blockchain, In this ideal period, we can not only achieve the Trust Finance that we orginally intend to do, but also separate "Fraud" "Money gimmick" and blockchain into unrelated fields, allowing blockchain to serve for Finance like internet technology, society or new Global layer technique; adding new features for blockchain 3.0.
What types of scenarios can updated blockchain 3.0 connected to ?
First is the cross region payment problems that is seeking most attention on the way to globalization; AITD Blockchain global cross region payment is going to achieve improvenment on efficiency , lowering cost, safety tracebility etc;First,traditional cross region payment is not time synchronized, banks are usually handle transactions in groups at the end of the day. Each transaction will need 24 hours or above to complete. Second, traditional cross region payment model is consisting large amount of human account checking and depending on third organizations, which causes high processing fee, according to the report (2016 global payment ) , completing a cross region payment through correspondent banks will usually cost 25 US dollars to 35 US dollars; In monitoring aspects, there are loopholes exisiting in traditional banks which is considering as centralized organization; Above AITD Blockchain, these problems can be perfectly solved through blockchain technology; Block chain +cross region payament will achieve P2P settlements, improving efficiency, lowering cost, blockchain Transaction transparency , information publicized, transaction record permenently saved traits realizing transaction record traceability.

We talked about the advantages of AITD Blockchain global cross border payments, in the process to achieve globalized payment, assets digitalization and information sharing functions are crucial; AITD Blockchain uses blockchain technology to achieve assets digitalization, what we called token, on chain token is easier to divide compare to traditional entity assets, flowing is more convenient,minimising transaction cost at the mean time; achieving assets digitalization through blockchain technique, all assets transaction record can be released to public ,transparent,permenent storage , traceable by using blockchain technology, these traits satisified the monitoring requirement compare to traditional entity assets; AITD can also achieve information sharing function when assets digitalization begin, AITD Block chain will build a safe reliable information sharing channel through block chain irreversible traits and consensus algorithm,realizing information transparency.
To build blockchain 3.0, solving corporation financing,loan etc most commonly meet problems are the required functions for AITD Blockchain; In the whole financial supply chain, middle, small, micro sized corporations are most difficult to achieve financing, The main reason is shortage of efficient credit mechanism between Banks and middle, small corporations. AITD Blockchain's mission is building Trust between loan providing financial organization and small, micro coporation;AITD Blockchain is building completely supply chain financing system, ensuring data reliability of supply chain core coporation through blockchain private key signature techniques, uploading contract, invoices on the chain, achieving value delivery for assets digitalization; After blockchain is solving data reliability and value flow, banks and other financial organizations will not process single evaluation for middle, small size corporation, but they are evaluating through core corporation's will of payment , invoice and data on chain, middle, small, micro corporation financing memorizing, achieving transpassing from single node financing to whole chain financing, therefore minimising the financing cost and solving financing difficulties.

The Different Types of Crypto Wallets

Cryptocurrency wallet is a set of private and public keys that validates the ownership of a digital asset (e.g. Bitcoin), and allows the wallet owner to send and receive digital assets or even store them. There are several types of wallets that can store your crypto holdings, some more secure than other, some are easily accessible and some are dedicated to certain assets. There are two types of wallets, Hot wallets and Cold wallets. The hot wallets are connected to the internet which makes transfers of coins and tokens faster and on hand, yet are more susceptible to viruses and hackers. The cold wallet refers to the cryptocurrency wallets that are offline. Generally cold storage is more secure, but are limited to a selection of coins and tokens you can store.
Software Wallets
Software wallets, as the name suggests, are downloaded and installed on desktops and laptops; they reside on a desktop which can only be accessed on that device where they are installed. They do provide a good level of security but many things could happen to your device, such as viruses or a hardware issue which could deny you access to the wallet, so its recommended to export your wallet private keys and store your login and password on a USB stick or on another device. You can re-install the software on a new device and use your login/password along with the exported private keys to access your funds. One of the most popular software wallets available for free is Exodus were you can store over a 100 cryptocurrency assets.
Paper Wallets
One of the first crypto wallets 1st used in the early 2010s which contains your wallet address, private keys and a QR code representing these keys, which eases the transfer and receiving of coins or tokens. Rather than typing each letter and number of the address which could be hectic, one can just scan the QR code and request or receive the asset. Paper wallets ensure security by preventing your private keys from being exposed online upon creation as its stored physically and not on a computer or online. Theoretically it is strong but physically it is weak, it’s great to have a free wallet that never exposes your private keys online at any point. A paper wallet is not made from a strong and durable material such as metal or plastic, paper can easily tear, burn, the print can fade away from sun exposer, it can get wet and even get lost. Therefore, many have considered this option of the past and are utilizing other safer options to store their cryptos. Here you can create your own paper wallet via the wallet generator.
Mobile/App Wallet
Mobile wallets are considered to be the most popular and commonly used type of wallets; they are apps installed on mobile devices and their main advantage is the swift accessibility to funds. Accessing a bunch of features such as sending, receiving, storing, spending. The user-friendly mobile wallet app like crypto.com has multiple services built-ins, you can do all the functions mentioned above, and you also have the option to stake your cryptos and earn profit, you can buy and trade cryptos to add to your existing portfolio at low fees and even request for a loan.
Many upcoming coins and tokens have used 3rd party wallets to store their coins or even have no supported wallets at the early stage which makes them fully dependent of exchanges to store their coins or tokens. Solid crypto projects typically build their own wallets at an early stage; during or post (ICO, IEO, public and private sale) when they distribute their coins/tokens to users. iOWNX is one of the projects that built a dedicated wallet where you can store both Ethereum and iOWN Tokens with several security measures to protect your assets. You can install the wallet app on both Apple and Android for free.
Hardware Wallet
Known as a “Cold Wallet” which is a physical device and considered to be the safest wallet. Hardware wallet securely stores your private and public keys and typically looks like a USB drive and is resistant to computer viruses. Long term crypto holders prefer a cold wallet as it remains offline most of the time. The wallets are made of metal and hard plastic with an input screen to insert your pin number and in case you lose the device, you can purchase another one and insert your 24-paraphrases known as seed key which was created on your previous device, and access your funds. There are several hardware wallets available in the market; the 2 most popular ones are the Nano Ledger that sell devices from $36 to $148 and the Trezor Wallet which goes for around the same price bracket.
Exchange Wallets
Exchange wallets access blockchain through a browser interface without having to download or install any software. The advantage of the exchange wallets is the ease of accessibility to funds if you are an active trader and require direct access to your funds to be able to trade, rather than transferring coins and tokens from a different wallet which could take some time and fees that disables you to instantly trade at a certain price. The downside of storing your cryptos on an exchange wallet is that some service providers hold and manage the wallet’s private keys on your behalf. Although this may sound more convenient for inexperienced users, it is surely not the best practice. When using cryptocurrency exchanges, you should consider that they provide a high security feature and protection tools such as device management, multi-factor authentication, anti-phishing code, and withdrawal address management. It is highly recommended to store the majority of your coins and tokens in a safer wallet and keep some on the exchange for trading purposes.
There are many types of wallets to choose from to securely store your cryptocurrencies, yet there is not a perfect wallet in existence. Your personal needs and requirements will ultimately guide you to the type of wallets that fits your need. If you are looking for a quick “send and receive” in a few taps then mobile app wallets could be an option. If you are more of a “hodler” and believe in long term store value then Hardware wallets could be the wallet for you. Presuming that you are a swing or an active crypto trader which requires your funds to be available on demand, then storing it on trading platforms and exchanges is convenient, as you can trade your coin or tokens for others and vice versa, instantly without the need to transfer, send and unlocking wallets to access your funds (which requires a bit of time and gas fees).
We hope that you found this guide helpful and that you will be able to find the right crypto wallet that fits your requirement. For more information, you can check out our video “Intro to Crypto Wallets“ which covers in details all types of wallets.

PRESS RELEASEWhy is Bitcoin superior over different cryptocurrencies?Akshay KSPublished a pair of weeks agoon August 12, 2020By Akshay KS
Source: Pixabay
During this technical world, bitcoin is the foremost used digital currency all over the world. However the main question then arises within the minds of the many folks is why bitcoin is considered the foremost superior over other cryptocurrenc Bitcoin Freedom
Bitcoin is that the one method of creating transactions daily as alternative currencies. But it's its options and uniqueness that make it superior. Bitcoin and different currencies are based mostly on the cryptographic algorithms or mathematics that are encrypted, with that the user becomes the owner of the currency. Bitcoin currencies are easily accessible at Bitcoin ATM and online exchange
The main feature of the bitcoin, which makes it superior is that it is the safest option for digital transactions. These will be used for on-line searching and transfer of money too.
There are many alternative blessings to using bitcoin. A number of them are mentioned below
Decentralized and digital
Bitcoin offers the freedom of exchanging the price without representatives that proves helpful in controlling the lower fees and high funds. Bitcoin is that the faster method of transaction than others. It is secure as it is free from theft and frauds and is constant. The main advantage is that bitcoin has its homeowners whereas the bank controls the money.
Makes online looking
Normally, bitcoin will be used for on-line shopping too. Bitcoin is the opposite face of e-wallet, that is created by blockchain technology that is used to store money and will easily pay everywhere digitally. For this reason, it also makes your searching easy by which you'll be able to look from your home solely

Bitcoin is accepted globally at each corner of the planet, which makes it less volatile than local currencies or cash. This feature makes it superior because it enables us to form transactions on-line and across the boundaries
Bitcoin unable the means of tracking cash

Bitcoin is created by blockchain technology. Blockchain is the sole technology which will either make it or break it. There are many computers which are used to keep up a permanent record of each bitcoin transactions with the help of cryptographic technique. In this approach, it becomes a lot of valuable together with the tracking of the payment. At the same time, there's no method of tracking the cash

While not any transformation method, it will be used over the entire world. It provides the simplest platform for the investment as it is free from the restrictions of governments or banks. It provides an open market and combines the simplest of gold and money.

Bitcoin provides the power to access the balance of the users with a password which is named a personal key. It additionally permits the exchange of values through the web without any middle person. Thus, bitcoin becomes safer, stuffed with privacy, and open to everyone
Unlike cash, it is not possible to form the duplicate quite bitcoin that makes it more efficient. It's protected with the technology of blockchain. Even if anyone tries to form a replica of bitcoin to use it, then the system will automatically reject it as the system recognize it as unknown

Bitcoin Freedom failed to allow two persons to transact on the one price. Once the bitcoin is transferred, its possession is also transferred. So this is the simple approach of maintaining records for any tax functions. It conjointly makes it a easy and healthier metho

Bitcoin is the foremost reliable manner of online transactions. Many questions arise in folks’s minds that are solved on websites like bitcoin revolution. One in all them was the above-mentioned question.

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.
