Was ist SHA-256? Definition und Erklärung Decentralbox

BitcoinSoV

BSoV: The first mine-able, deflationary, open sourced, decentralized cryptocurrency Hedge to act as a Store of Value against the monetary inflation of fiat currency. BSoV is mined using a simple Keccak256 (Sha3) algorithm. There is No ICO, No Pre-mine, and No Governance. This allows for BSoV to be completely decentralized and fairly distributed. With each transfer of BSoV tokens, 1% of the total transaction is burned forever.

Litecoin Cash

Litecoin Cash (LCC) is a fork of Litecoin itself utilizing an SHA-256 hashing algorithm. While the initial goal was to focus on bringing back SHA-256, along the way we created "Hive Mining," an agent-based system allowing everyday users to participate in securing and hashing the network to earn real LCC rewards. Be sure to visit our website @ https://litecoinca.sh for more information and join us on DISCORD to speak with the team and get free LCC rains just for chatting and being active!

TigerCoin TGC

TigerCoin TGC is a fork of Bitcoin version 0.8, with addition of super random blocks.

What if bitcoin used SHA-1 instead of SHA-256 ?

It takes new miners for the new PoW. Do you plan to make that some kind of exclusive club? What other PoW do you trust more? The new PoW would likely be insanely insecure for a time, regardless. The chance that former SHA-256 investors find ways to attack the new PoW in the early stages is very real, and creates a huge risk to the network. You propose taking the most secure network on the planet and suddenly making it one of the most insecure ones.
How do you propose to change PoW? One day SHA-256 the next day DaggerHashimoto? Really am curious!
I happen to be with Gavin on this one . Bitcoin is the longest chain (including difficulty). Luke you still have that today, but don't get reckless or someday you may not...

[Draw #59] It’s almost time to see who our winner is, the draw awaits!

Here’s the part where we get one in the crowd.

TL;DR - This post is for the sole purpose of choosing a winner. If you commented in this [Drawing Thread], you are entered in the drawing and don't need to do anything else. By 16:00 UTC, the winner will be selected. The Bitcoin (BTC) blockchain will be used to pick this winner. This can be verified at any device running Python 3.5, and you do not need to own Bitcoin in order to participate.
Additionally, all information to replicate the Drawing at home is available on Dropbox and GitHub, scroll down for more information.
Importantly, this post WILL NOT BE EDITED in order to keep the integrity of the Drawing. To verify this, there will not be an asterisk during the time passed since its creation. The winner will be announced in a stickied comment.
DISCLAIMER: Some of the information may be unrevised, but procedures are the same as prior draws. Thank you.
Off Topic:
The [Discussion] Thread at /millionairemakersmeta is open. All comments are welcome there for any inquiries.
[Discussion for Fall and Winter 2020-2021]: https://old.reddit.com/millionairemakersmeta/comments/iw8mse/_/
Explanation!
The Bitcoin (BTC) blockchain will be used to choose a winner. Once the time listed has passed, there will be an active check to determine the blockchain's winning hash. Like before, this subreddit will wait for the 3rd Block after the time (being 16:00 UTC) to select the winner.
If a block is discovered by 15:59 UTC, it will not be counted towards the counter of three blocks. If it's discovered by 16:00:00 UTC, then it will decrease the counter. This can be checked by seeing the timestamp given to it by blockchain explorers.
You are able to see how this subreddit will verify the winner by checking the GitHub repository, which also includes a back-up plan in case of an emergency.
Standard Protocol:
This post will not be edited! This is to prevent tampering of the hash or files by any of the moderators. To prove this, look for the lack of an asterisk near the time since creation.
To verify if a hash for a file is that of Draw #59, upload the file of choice to a SHA-256 generator, and match it with its respective hash output. The result you receive should be the same as what is listed here.
If you are interested in doing this for yourself, download Python 3.5 or better and follow the path to the folder labeled: MM59
Status Reports:
I will be commenting on the progress of the drawing via the comments, so other users can keep track of the progress. These comments will be pinned at the top of the post and be distinguished. Most likely, after 1:00 PM ET, the pinned comment will be announcing the winner.
If you can run Python yourself and follow the instructions, you will be able to find the winner. Make sure the hash released from the blockchain and the total number of participants match with what is described below. In addition, thank you for your patience.

Overwhelmed!

I am not really savvy in coding. So, the sequences of letters and numbers involved are driving me a bit crazy.
Here is what I have done:
Downloaded AwesomeMiner and as a wallet, I used Electrum. Surprisingly, when I check the bitcoin reddit, these two apps are not mentioned. Am I in the wrong track?
Now, in AM app, I used SHA-256 algorithm, BFGMiner(5.4.2), as as a pool, I used bsod mining pool.
BUT, this is what I got:
> [2020-10-16 20:18:53] No devices detected!
> [2020-10-16 20:18:53] Waiting for devices
> [2020-10-16 20:18:53] Probing for an alive pool

> [2020-10-16 20:18:53] Probing for an alive pool
Mining Engine Process started, PID: 10480
Even I understand that the mining is not working at all.
Just wondering what should I do now?

However, I check out some video on the bitcoin reddit, so I will start from there.

Any advices are welcome.

Checker Thread (A list of hacked clients for easy reference)

Community contribution is the only way this thread will be useful. This is a WIP! More clients will be added as time goes on!
Quick note: The vast majority of these are files supplied by the community -- some may not work. The person who sent me 9b9t says it doesn't work, but I have not personally tested. Please let me know if it works or does not work.

Some additional notes:
I am open to community criticism so long as it can actually be used to benefit the thread. Issues with formatting, approach, client choice, etc. are all great things to come talk to me about so I may improve. However, people keep commenting the same things over and over and over — “VirusTotal can’t catch X” is a popular one — and I don’t have time to deal with it. If you have a security concern, you are more than welcome to raise it. HOWEVER, do not make unreasonable requests of me — I work, in addition to that I have a social life, I have responsibilities at home as well. This is a side thing that I do when I have the time. A lot of people have suggested looking through bytecode to determine if a client is malicious. I do not have the time to do this for every client. If you are willing to help and do more than say “you should do more than you already are, even though you have a job and a life outside of an obscure subreddit,” feel free to DM me. People who take the broken record approach and say things that are already covered in the thread, or refuse to offer help and just post complaints, will be blocked and ignored. I’m all down for making this post better, but I’m not gonna waste my time with people who won’t work with me. Thank you for your help!

BIG THANKS TO u/jpie726 FOR HIS MASSIVE CONTRIBUTIONS! WITHOUT HIM THIS LIST WOULD BE SIGNIFICANTLY LESS EXPANSIVE. GO UPVOTE THIS MAN INTO HEAVEN, HE DESERVES IT!

Eventually I would like to make a Python script that takes care of all the necessary tasks to install these clients. Python itself is available through the Windows Store as well as on Python's website, or through various other installers. It will install any additional dependencies via Pip and will use Curl to retrieve the files. Anyone interested in helping with this script is more than welcome to do so, if you wish. The two options for assisting me would be as follows:
1. You can install Visual Studio Code or Atom and work with me directly through those applications (more details soon™)
2. A GitHub page may be made and you could submit pull requests through that and edit the script alone.

#######################################################################
There is a misconception that I am only here for free paid clients.
1. I can't use a paid client unless I have access to a cracked version, an account, and the HWID bound to said account.
2. People are also saying there's a way for clients to track if someone leaks them. While I suppose this is possible if they bothered to put in the absurd amount of effort it would take, it would give them no benefit and it would do no good as I am not running the software on my desktop -- I am sending the software to VirusTotal, grabbing the SHA-256 checksum, and deleting the file.
3. If all you're going to do is post that "VirusTotal can't catch x" or "muh client" do not waste my time, and don't waste yours. You will be ignored in favor of people who will actually help me construct what I hope to be a megathread for this subreddit, FOR YOU GUYS. I mean jeez, someone's trying to help and half the fucking responses are "muh client" like come on. No wonder this fucking subreddit is dead, sheesh. If someone's trying to help you and you just step on their toes that's just not very cool, not everyone is trying to scam you. I do just be trying to help people who come here doe.
4. If you have concerns, raise them respectfully. Do not attack me, you will be ignored or if I feel so inclined I will give you 110% of the shit you give me right back to you. I will answer questions, I will elaborate on my goals, I will take helpful advice. Everything else will be outright ignored, and misinformation will be countered. That is all, thread below.
#######################################################################

I named this the Checker Thread to make it easy to search for in the subreddit. Enjoy.Below will be a list of hacked clients, with VirusTotal links, SHA-256 hashes, direct download links (skipping ad pages) and eventually features for each client. I'd also like to add what servers they do and don't work on, but I need the community to help with that.
The only client I use is Impact, send me additional clients in the comments and they will be added to this list.

Note about SHA-256 hashes:
SHA-256 hashes are a hash of a file produced algorithmically. This type of hash was developed by the United States National Security Agency, and is typically used to verify that files are what they are supposed to be. Widely used in cryptographic applications such as SSH, APT repositories, transactions on websites, verifying files, Bitcoin, and more. It is very common. This type of cryptographic hash has been in use since 2001. An SHA-256 hash will be the exact same for the same file regardless of the source of the file, so if your hash is different from the one listed here you do not have the legitimate installer OR the hash is not up-to-date.

Note about VirusTotal tests:
Several people have pointed out to me something I feel should be brought up in the main thread. VirusTotal is not a catch-all, just as your typical antivirus software is not a catch-all. It will not catch everything. It should be used as a general guideline only. Clean VirusTotal tests do not guarantee your safety, although if the program passes all ~70 or so antivirus engines it's probably safe to use. Any additional malicious activity should be caught by your antivirus program's heuristics. I take no responsibility for anything that is malicious, but I can say in good conscience that I have done everything I can to ensure that everything on this thread is safe. Keep in mind that programs that trip VirusTotal may still be safe to use, antivirus programs often pick up injectors as malware or Trojans because that's how those types of viruses behave in the real world. Use your best judgement. If your best judgement is not good enough, do not use these programs. You have been warned.

Tron v11.1.3 (2020-08-20) // Minor updates; Remove PCHunter due to A/V false positives

Background

Tron is a script that "fights for the User."
It aims to automate ~87% of the tedious work in getting a badly-running Windows system back on its feet (clicking "next" in a/v scan windows, etc); with much left to the discretion of the tech.
It is built with heavy reliance on community input and updated regularly.
It is NOT a system optimization or "baseline" script.
Read the instructions.

Sequence of operation

Prep > Tempclean > De-bloat > Disinfect > Repair > Patch > Optimize > Wrap-up | Manual tools
Saves a log to C:\logs\tron\tron.log (configurable).
screenshots of Tron in action

Changelog

(significant changes in bold; full changelog on Github)
v11.1.3 (2020-08-20)
- Removed PCHunter utility (extra utility, Tron never ran PCHunter) due to false positives with many A/V engines
. Minor definition updates

Download

  1. Primary method: Download the .torrent.
  2. Secondary: Download a self-extracting .exe pack from one of the mirrors:
    Mirror HTTPS HTTP Location Host

You made your comments, it’s time to see who our winners! [Draw #54]

Honestly, with how effective the new source code is, it may be easier to automate this process. Let’s not get ahead of ourselves, we’re picking a winner!

TL;DR - This post is for the sole purpose of choosing a winner. If you commented in this [Drawing Thread], you are entered in the drawing and don't need to do anything else. By 16:00 UTC, the winner will be selected. The Bitcoin (BTC) blockchain will be used to pick this winner. This can be verified at any device running Python 3.5, and you do not need to own Bitcoin in order to participate.
Additionally, all information to replicate the Drawing at home is available on Dropbox and GitHub, scroll down for more information.
Importantly, this post WILL NOT BE EDITED in order to keep the integrity of the Drawing. To verify this, there will not be an asterisk during the time passed since its creation. The winner will be announced in a stickied comment.
DISCLAIMER: Some of the information may be unrevised, but procedures are the same as prior draws. Thank you.
Off Topic:
The [Discussion] Thread at /millionairemakersmeta is open. All comments are welcome there for any inquiries.
[Discussion for Spring and Summer 2020]: https://reddit.com/millionairemakersmeta/comments/g3a53t/_/
Explanation!
The Bitcoin (BTC) blockchain will be used to choose a winner. Once the time listed has passed, there will be an active check to determine the blockchain's winning hash. Like before, this subreddit will wait for the 3rd Block after the time (being 16:00 UTC) to select the winner.
If a block is discovered by 15:59 UTC, it will not be counted towards the counter of three blocks. If it's discovered by 16:00:00 UTC, then it will, simple. This can be checked by seeing the timestamp given to it by blockchain explorers.
You are able to see how this subreddit will verify the winner by checking the Dropbox folder, which also includes a back-up plan in case of an emergency.
Standard Protocol:
This post will not be edited! This is to prevent tampering of the hash or files by any of the moderators. To prove this, look for the lack of an asterisk near the time since creation.
To verify if a hash for a file is that of Draw #54, upload the file of choice to a SHA-256 generator, and match it with its respective hash output. The result you receive should be the same as what is listed here.
If you are interested in doing this for yourself, download Python 3.5 or better and follow the path to the folder labeled: MM54
Status Reports:
I will be commenting on the progress of the drawing via the comments, so other users can keep track of the progress. These comments will be pinned at the top of the post and be distinguished. Most likely, after 1:00 PM ET, the pinned comment will be announcing the winner.
If you can run Python yourself and follow the instructions, you will be able to find the winner. Make sure the hash released from the blockchain and the total number of participants match with what is described below. In addition, thank you for your patience.

RESEARCH REPORT ABOUT ARYACOIN

RESEARCH REPORT ABOUT ARYACOIN
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/a7jv4azk86u51.jpg?width=1600&format=pjpg&auto=webp&s=e4a4dbb5afacd5747076beaa59e6343b805c3392

ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.
Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:
  • Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.
  • Instant operations: Aryacoin makes it quite easy for you to use your digital wallet and perform various operations with it.
  • Safe and secure: all your data is stored encrypted and can only be decrypted with your private key, seed, or password.
  • Strong security: The system has no control over your wallet. You are 100% in charge of your wallet and funds.

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
  • The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
  • The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
  • The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
  • There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
  • The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
  • The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

CryptoSmarts 4: The Best Free Password Managers

CryptoSmarts 4: The Best Free Password Managers
MintDice is proud to bring you the fourth part of the CryptoSmarts series, a 100% unbiased/non-affiliate paid article set that will focus on relatively simple ways you can boost your privacy, take power away from overbearing governments and corporations while also doing relative good for society all at the same time with minimal effort. Rest assured that anything suggested here is solely for your own benefit.
In this article, we'll take a deep dive into password managers, which applications to go for, how to optimize your password managers and which ones to avoid. It's of increasing importance for all users to adopt a password manager because commonly used passwords and repeated use of log-in + password combinations are the two weakest points in any normal individual's security online. Meanwhile, memorizing dozens of unique and complex passwords is beyond the scope of what most people can do, especially long term. Thus password managers have been created as a way to store multiple passwords into a single file that can help ensure your security and privacy online.
For a little encouragement, we'll share the now extremely famous dialogue between Edward Snowden and John Oliver talking about passwords. As should be painfully obvious by now, password managers are one of the best solutions to this entire dilemma.

https://preview.redd.it/ribbtjwz1it51.png?width=1000&format=png&auto=webp&s=3c3a9a31bdb8c4f9ec83bea98638fec5dd78b38f

PASSWORD MANAGER BASICS

We should first note that not all password managers are created the same as we've noted with software across all of our other articles. By and large, we'll be looking for similar characteristics in our password managers as we would our other software which includes open sourced software protocols and best software security practices. And when it comes to Bitcoin, cryptocurrency and your entire life's work on the internet, there is a lot at stake here. I'd argue that it is more important for password managers than for any other application to make sure to get this one correct since it will have your entire livelihood on the line.
The very amazing thing with demanding open sourced software for your password manager is that it by definition will also be free at the most basic level. This is because if it weren't, all it would take would be someone to fork over a program to make it free. So you are in a sense getting the best of both worlds here; a free software that is also of the highest quality. Meanwhile, ironically, many of the more commonly known password managers like Dashlane or Lastpass use closed source software and often charge fees to use their service. Funnily enough, Lastpass, the password manager itself, was actually formerly hacked in the past. One could argue this at least in part had to do with it's closed source software since having open sourced software at least in part makes software more secure. In short, do not used these closed source services that are frequently advertised for on the web as they are detrimental to you in more ways than one.

RECOMMENDED BEST PASSWORD MANAGERS

Bitwarden is our first recommendation. Bitwarden is truly one of the all time greats by approaching password management on the individual, team and even enterprise level to create a one size fits all solution. Bitwarden is compatible on virtually all devices out there from all desktops to mobile devices and so forth. Additionally, while they offer a centralized cloud service for free, Bitwarden is also set up to allow you to run your own private server to keep your own key base entirely under your own control, fully encrypted.

https://preview.redd.it/zmlkf5d12it51.jpg?width=770&format=pjpg&auto=webp&s=02998b777d05ab00557a97c616a4b0d505b324aa
Next up we have KeePassXC which is a fork of one of the longest standing password managers in existence, formerly known as KeePass that halted a lot of it's ongoing development some time ago. KeePassXC was created as a locally held password manager application that could work across platforms. Unlike Bitwarden where your key file is held in cloud storage, KeePassXC is simply a program client and a local file that you must maintain and backup yourself. This has some pros and cons. The good news is that you have full control of everything related to KeePassXC as the program under most situations will not be talking to any online server which could expose private or sensitive information. The bad news is that if you ever were to lose control of your key file, you are completely out of luck. For this reason, it's imperative to back up your encrypted key file in multiple locations to protect against what would be catastrophic loss. You can do this with USB drives, e-mail accounts, cloud storage, safe deposit boxes or a whole host of other creative solutions that you might come up with.
The final recommended option is LessPass. LessPass is very interesting technology because it is a no-knowledge password manager. By inputting a few pieces of information which could be a master password in conjunction with an e-mail address or user name, a password is automatically attached to any URL address. It will simply cross all of these pieces of information via PBKDF2 and SHA-256 to produce random yet consistent outputs for any of your web browsing. The advantage of this program is that it is extremely light weight, and so long as you can remember your e-mail address, account name and master password, you can now gain full access to everything around the internet without the need of any files. The downside is some level of control over password flexibility since the passwords are automatically generated for you.
In summation of these three options, BitWarden is the best overall password manager for most people's use cases. Meanwhile, LessPass is probably best suited for the most casual user who contains fewer accounts across the internet and wants something extremely simple and easy to use. Lastly, KeePassXC, will be the ultimate in privacy password manager technology and is best suited for those that are prepared to take the extra steps to ensure their key file is kept up to date as the months and years tick by.

https://preview.redd.it/r4icjup22it51.jpg?width=1920&format=pjpg&auto=webp&s=622cf1b967ec5622e3feb2b49e5ac29917629cdf

BEST PRACTICES WITH YOUR NEW PASSWORD MANAGER

Once you have chosen a password manager from the above list, it will be important to change all of your account passwords one by one to incorporate it into your new system. This will help you get away from your commonly used log-in and password combinations and over to your new, more secure and robust set up. With your new set up, if you have a key file to back up, you must now start getting in the habit of doing so, especially after major or important changes to your password manager. Or if you wish to use BItWarden with a private cloud server, make sure that that is fully set up and running.
Generally speaking, when choosing password length from your password manager for standard and robust security, 25 random characters, letters (and symbols if you wish, but they aren't necessary), is mostly considered to be uncrackable. This is because while every password is in theory beatable, it takes dramatically more computational energy over time to figure out what your password is, and at some point, it becomes unreasonable. That said, NSA grade security often holds itself up to 50 random characters which is considered to be unbreakable even on a government wide scale.
On that same token, you'll have to use a master password for your password manager. Given that you only need to know one password, it will now be extremely important to make this a very good password. Because a password that you need to remember most likely won't (or perhaps shouldn't) be completely random so that it's easy to remember, it should, at the very least, be long. I would suggest making sure that you come up with a master password that is at least 40 characters long or 125 bits of information. To check out how many bits of entropy your master password is, you can type it into the password field of KeePassXC and it will tell you roughly how secure your master password is. While 40 characters may seem like a lot, do keep in mind that this is now the only gateway between yourself and all of your access keys to all of your accounts held on this account.

Bits of Entropy Example on KeePassXC
Finally, it is worth investing in a YubiKey or similar 2-FA device if you can get one. This can apply to BitWarden and KeePassXC. With the normal password managers, a hacker will need access to not only your password but also your key file in order to have free reign over all of your accounts. However, a sophisticated hacker that has full access to your device with a keylogger could ultimately, in theory, compromise your full set up, and this would be disastrous for you. Fortunately, this can be resolved by buying and activating a Yubikey or other such device. The Yubikey example requires that a Yubikey, with a private key that you set up for your password manager, is present to access your database. Therefore, even if a hacker were to obtain your key file and your master password, they still won't be able gain access to your account. As a precaution, however, if you lose access to your Yubikey and/or private key, you too, will be locked out. Therefore, it is important to keep your Yubikey backed up and to keep extra copies available.

IN CONCLUSION

Owning Bitcoin or other cryptocurrencies comes with a lot of responsibility if you want to minimize risk. As does maintaining a strong hack-resistant presence online. One of the best defenses you can make is by implementing a password manager. Similar to the previous CryptoSmarts articles that we have written prior, it will take some small amount of set up work to get fully acclimated to your new system, but you'll thank yourself down the road that you have done this. And the sooner you start, the better, as things will only continue to get more complex, with more risk factors at play as the internet plays an ever increasing role in all of our day to day lives.
Finally, while the article is current as of the writing of the article, it will undoubtedly lose merit over time. Be sure to check if everything in this article is up to date or that any password manager that you select from this article continues development or continues to abide by the proper best practice principles.
If you enjoyed this article, we would encourage you to check out our other previous CryptoSmarts articles discussing private e-mails, secure messenger applications and proper web browsers.

Solusi dari Bitcoin

Mari kita pelajari teori lebih mendalam dari Bitcoin.
  1. Aset dan transaksi ledjer (ledger)/sejarah
Kalian tahu ga apa itu ledjer. Sebenarnya ledjer itu adalah rekor komplit untuk aktivitas ekonomi.
Blockchain (rangkaian blok) itu tamper-proof (tidak bisa diubah) berhubungan dengan ledjer.
SHA-256 itu adalah kriptografik hash dimana bisa dipakai untuk konfirmasi integritas dan autentik transaksi. Sebuah algoritma yang membentuk 256-bit (32 byte) hash
Dulunya orang memakai ledjer untuk rekor aktivitas ekonomi yakni buku catatan. Tapi sekarang ini ledjer disimpan dalam sistem komputer. Sebenarnya pencatat buku ini atau penyimpan ledjer sekarang ini ga aman loh. Mereka bisa saja dapat uang suap untuk mengganti nama pemilik tanah. Selain itu, rekor data pun bisa saja hilang tanpa sengaja.
Selama ini sejarah transaksi kita untuk banking, kartu kredit, financial statement perusahaan, reservasi hotel, data apapun yang berhubungan dengan passport, memang semua disimpan si 'penjaga' buku. Kalau dipikir pikir, aman sih semua aktivitas kita di rekor oleh centralized keeper?
Sekarang apa nih solusi Bitcoin? BITCOIN ini decentralized ledger dan ada 3 manfaat besar -tidak dirahasiakan -tidak bisa dipalsukan datanya -data tidak akan pernah hilang
Kenapa Bitcoin? Dulunya komputer di tahun 1975 kemudian Internet tahun 1993 lalu sekarang Bitcoin tahun 2014. Caranya adalah, bitcoin akan mengantar porsi kecil dari properti digital dari yang satu ke yang lain. Bitcoin menjamin keaslian transaksi tersebut, aman juga.
Bitcoin ini didukung oleh konsensus yang terbentuk dari jutaan orang didunia. Bitcoin 'white paper' (kertas putih) ditulis tanggal 31 Oktober 2008.
  1. Bitcoin untuk selesaikan permasalah Jeneral Byzantine
bitcoin itu adalah unit mata uang Bitcoin itu adalah konsep, networking Bitcoin alamat terdiri dari banyak kata-kata dengan angka-angka dimana bitcoin dapat dikirim Blockchain (rangkaian blok) adalah catatan lengkap transaksi untuk bitcoin, ataupun disebut ledjer publik
Adapun kegunaan dari BITCOIN REFERENCE CLIENT SOFTWARE untuk menyimpan semua sejarah transaksi. Tidak ada sistem sentral yang mengontrol penyimpanan transaksi. Ini hanya dipakai di antara Clients.
Bitcoin mengkonfirmasikan transaksi melalui proses 'mining'. Mining ini akan menciptakan bitcoin baru dengan setiap blok. Seperi Bank yang bisa menciptakan uang kertas baru. Namun, bitcoin ada jumlah maksimalnya yaitu 21 juta. Bitcoin dapat menjaga integritas dari setiap blok melalui tenaga komputer (proof-of-work)
Tahap pertama - Miners (penggali) akan mengumumkan transaksi dengan blok dan mengverifikasikan semua itu sah. Tahap kedua - Aplikasikan fungsi dari kriptografik hash dari blok sebelumnya ke blok selanjutnya Tahap ketiga - Selesaikan Proof-of-work
Kalau blok itu berhasil diselesaikan maka akan ada hasil penghargaan. Kesusahan untuk menyelesaikan blok transaksi adalab setiap 2016 blok (lebih kurang dua minggu) jadinya network bitcoin membentuk satu blok yang sah setiap 10 menit. Pakai komputer lama ataupun baru tetap akan membentuk blok setiap 10 menit.
Mari kita bahas sedikit tentang proof-of-work, sistem ini adalah kunci elemen untuk sekuritas ledjer. Ini untuk mencegah pencurian data dari hacker.
Penggali (miner) yang memiliki setidaknya 50% tenaga hash dalam sistem. Ketika seorang penggali memiliki tenaga hash melebihi 50% maka dia akan punya rangkaian yang lebih panjang dari penggali lainnya. Ini akan berdampak buruk karena dia dapat mencegah bitcoin untuk bertransaksi.
Oleh karena itu, untuk menjaga kejujuran ekosistem maka seorang penggali mengamankan hanya 50% sistem komputer dan tak lebih.

Premining SHA-256 hashes

Could someone explain how SHA-256 works in bitcoin and specifically how hashes are generated and what qualities a hash must have to be considered valid? Im trying to understand more of the technical side of bitcoin, and I think I have a misunderstanding. Is the only requirement for the next hash to be smaller than the hash of the previous block? And if thats the case would someone not be able to "premine" obvious smaller hashes and then just add them to the blockchain to make their chain the longest?
Thanks you for any and all help!

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!
