ABSTRACTAryacoin 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.INTRODUCTIONThe 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 ARYACOINAryacoin 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 HISTORYAryacoin (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 GOALAryacoin’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 SOLVEAryacoin 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 ARYACOINAryacoin solution offers the following benefits:
1.1.5 ARYACOIN FEATURES1. 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!
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 EXCHANGEAryana, the first Iranian exchange is a unique platform with the following features:
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-WORKThey 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 NETWORKThe steps to run the network are as follows:
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 ARYACOINThe 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 SOLUTIONOne 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.

(1) Proper multi-signature cold wallet storage.
(a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet.
(b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time).
(c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.
(d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds.
(e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers.
(2) Regular and transparent solvency audits.
(a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row.
(b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored.
(c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process.
(d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify.
(e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible.
(3) Protections for hot wallets and transactions.
(a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets.
(b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy.
(c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage.
(d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange.
(e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.
Until one understands the basics of this tech, they won’t be able to grasp or appreciate the impact it has on our digital bank, Genesis Block.submitted by mickhagen to genesisblockhq [link] [comments]
This is the second post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
Our previous post set the stage for this series. We discussed the state of consumer finance and how the success of today’s high-flying fintech unicorns will be short-lived as long as they’re building on legacy finance — a weak foundation that is ripe for massive disruption.
Instead, the future of consumer finance belongs to those who are deeply familiar with blockchain tech & decentralized protocols, build on it as the foundation, and know how to take it to the world. Like Genesis Block.
Today we begin our journey down the crypto rabbit hole. This post will be an important introduction for those still learning about Bitcoin, Ethereum, or DeFi (Decentralized Finance). This post (and the next few) will go into greater detail about how this technology gives Genesis Block an edge, a superpower, and an unfair advantage. Let’s dive in…
Bitcoin: The First CryptocurrencyThere are plenty of online resources to learn about Bitcoin (Coinbase, Binance, Gemini, Naval, Alex Gladstein, Marc Andreessen, Chris Dixon). I don’t wanna spend a lot of time on that here, but let’s do a quick overview for those still getting ramped up.
Cryptocurrency is the most popular use-case of blockchain technology today. And Bitcoin was the first cryptocurrency to be invented.
Bitcoin is the most decentralized of all crypto assets today — no government, company, or third party can control or censor it.Bitcoin has two primary features (as do most other cryptocurrencies):
The fact that there are so few things one can do with Bitcoin is one of its greatest strengths.Its design is simple, elegant, and focused. It has been 10+ years since Satoshi’s white paper and no one has been able to crack or hack the Bitcoin network. With a market cap of $170B, there is plenty of incentive to try.
Public AwarenessA few negative moments in Bitcoin’s history include the collapse of Mt. Gox — which resulted in hundreds of millions of customer funds being stolen — as well as Bitcoin’s role in dark markets like Silk Road — where Bitcoin arguably found its initial userbase.
However, like most breakthrough technology, Bitcoin is neither good nor bad. It’s neutral. People can use it for good or they can use it for evil. Thankfully, it’s being used less and less for illicit activity. Criminals are starting to understand that transactions on a blockchain are public and traceable — it’s exactly the type of system they usually try to avoid. And it’s true, at this point “a lot more” crimes are actually committed with fiat than crypto.
As a result, the perception of bitcoin and cryptocurrency has been changing over the years to a more positive light.
Bitcoin has even started to enter the world of media & entertainment. It’s been mentioned in Hollywood films like Spiderman: Into the Spider-Verse and in songs from major artists like Eminem. It’s been mentioned in countless TV shows like Billions, The Simpsons, Big Bang Theory, Gray’s Anatomy, Family Guy, and more.
As covid19 has ravaged economies and central banks have been printing money, Bitcoin has caught the attention of many legendary Wall Street investors like Paul Tudor Jones, saying that Bitcoin is a great bet against inflation (reminding him of Gold in the 1970s).
Cash App already lets their 25M users buy Bitcoin. It’s rumored that PayPal and Venmo will soon let their 325M users start buying Bitcoin. Bitcoin is by far the most dominant cryptocurrency and is showing no signs of slowing down. For more than a decade it has delivered on its core use-cases — being able to send or store value.
At this point, Bitcoin has very much entered the zeitgeist of modern pop culture — at least in the West.https://preview.redd.it/dnuwbw8mfu951.png?width=800&format=png&auto=webp&s=6f1f135e3effee4574b5167901b80ced2c972bda
Ethereum: Programmable MoneyWhen Ethereum launched in 2015, it opened up a world of new possibilities and use-cases for crypto. With Ethereum Smart Contracts (i.e. applications), this exciting new digital money (cryptocurrency) became a lot less dumb. Developers could now build applications that go beyond the simple use-cases of “send value” & “store value.” They could program cryptocurrency to have rules, behavior, and logic to respond to different inputs. And always enforced by code. Additional reading on Ethereum from Linda Xie or Vitalik Buterin.
Because these applications are built on blockchain technology (Ethereum), they preserve many of the same characteristics as Bitcoin: no one can stop, censor or shut down these apps because they are decentralized.One of the first major use-cases on Ethereum was the ability to mint and create your own token, your own cryptocurrency. Many companies used this as a way to fundraise from the public. This led to the 2017 ICO bubble (Initial Coin Offerings). Some tokens — and the apps/networks they powered — were fascinating and innovative. Most tokens were pointless. And many tokens were outright scams. Additional token reading from Fred Ehrsam, Balaji, and Naval.
Digital Gold RushJust as tokens grew in popularity in 2017–2018, so did online marketplaces where these tokens could be bought, sold, and traded. This was a fledgling asset class — the merchants selling picks, axes, and shovels were finally starting to emerge.
I had a front-row seat — both as an investor and token creator. This was the Wild West with all the frontier drama & scandal that you’d expect.Binance — now the world’s largest crypto exchange —was launched during this time. They along with many others (especially from Asia) made it really easy for speculators, traders, and degenerate gamblers to participate in these markets. Similar to other financial markets, the goal was straightforward: buy low and sell high.
That period left an embarrassing stain on our industry that we’ve still been trying to recover from. It was a period rampant with market manipulation, pump-and-dumps, and scams. To some extent, the crypto industry still suffers from that today, but it’s nothing compared to what it was then.
While the potential of getting filthy rich brought a lot of fly-by-nighters and charlatans into the industry, it also brought a lot of innovators, entrepreneurs, and builders.The launch and growth of Ethereum has been an incredible technological breakthrough. As with past tech breakthroughs, it has led to a wave of innovation, experimentation, and development. The creativity around tokens, smart contracts, and decentralized applications has been fascinating to witness. Now a few years later, the fruits of those labors are starting to be realized.
DeFi: Decentralized FinanceSo as a reminder, tokens are cryptocurrencies. Cryptocurrencies can carry value. And value is a lot like money. Because tokens are natively integrated with Ethereum, it’s been natural for developers to build applications related to financial services — things like lending, borrowing, saving, investing, payments, and insurance. In the last few years, there has been a groundswell of developer momentum building in this area of financial protocols. This segment of the industry is known as DeFi (Decentralized Finance).
In Q2 of 2020, 97% of all Ethereum activity was DeFi-related. Total DeFi transaction volume has reached $11.5B. The current value locked inside DeFi protocols is approaching $2 Billion (double from a month ago). DeFi’s meteoric growth cannot be ignored.
Most of that growth can be attributed to exciting protocols like Compound, Maker, Synthetix, Balancer, Aave, dYdX, and Uniswap. These DeFi protocols and the financial services they offer are quickly becoming some of the most popular use-cases for blockchain technology today.
This impressive growth in DeFi certainly hasn’t come without growing pains. Unlike with Bitcoin, there are near-infinite applications one can develop on Ethereum. Sometimes bugs (or typos) can slip through code reviews, testing, and audits — resulting in loss of funds.
Our next post will go much deeper on DeFi.
Wrap UpI know that for the hardcore crypto people, what we covered today is nothing new. But for those who are still getting up to speed, welcome! I hope this was helpful and that it fuels your interest to learn more.
Until you understand the basics of this technology, you won’t be able to fully appreciate the impact that it has on our new digital bank, Genesis Block. You won’t be able to understand the implications, how it relates, or how it helps.
After today’s post, some of you probably have a lot more questions. What are specific examples or use-cases of DeFi? Why does it need to be on a blockchain? What benefits does it bring to Genesis Block and our users?
In upcoming posts, we answer these questions. Today’s post was just Level 1. It set the foundation for where we’re headed next: even deeper down the crypto rabbit hole.

Cryptomarketing in 2020: successful application of strategies from MLM and the beauty industry
Over the past decade, the crypto-industry has proven to be a unique industry with a specific audience, which requires a no less specific approach. In this regard, in 2020, the advertising activity of crypto companies is significantly different from that to which banks and various financial companies resort. Industry leaders prefer not to rely on traditional online advertising on Facebook, Instagram and YouTube. They follow a different path: they work with bloggers (opinion leaders and influencers), rely on MLM marketing referral programs and actively organize various contests and sweepstakes with generous prize pools. The CoinDesk portal claims that crypto marketing this year is strikingly reminiscent of marketing in the beauty industry, and here it is no less effective.
General conceptMichelle Fan, a blogger with a million YouTube subscribers, is using the same techniques to spread skin care life hacks and the idea of financial freedom through bitcoins. Moreover, she assures that the leaders of the crypto industry, like her, use marketing schemes from the beauty industry, even if they themselves do not know about it.
Both areas prefer to use the DTC (Direct to Customer) business scheme, independently creating and then promoting and selling goods / services, working as closely as possible with the community. Sales are built through aggregated retail platforms like Amazon, Etsy and Shopify, or even through accounts in popular social networks.
Industry leaders in developing countries often resort to the latter option, where large sites like Amazon simply don’t work or aren’t popular. For example, Michelle Haber, a bitcoin maximalist from Libya, made it clear in CoinDesk’s comment that social networks and chats are today the most effective way to distribute goods / services in crypto topics. He said that local traders in order to “educate” the audience help buy hardware wallets, selling them through groups on social networks. Buying yourself Trezor or Ledger in another way is often simply impossible.
Work with opinion leadersMichelle Fan is not the only person from the crypto-community who notices the similarities with the beauty industry. So, Maria Paula Fernandez, who actively uses the services of the DeFi sector and is seriously interested in the topic of skin care, gave the CoinDesk portal a similar comment.
She notes that in both cases, society has become accustomed to relying on the opinion of society itself, rather than trusting the views of the world’s leading media. Therefore, in both sectors, the so-called influencers are very popular — opinion leaders and bloggers who disseminate information among their audience on YouTube, Instagram, TikTok and other social networks, receiving a reward for this.
Crypto-companies very often, like firms from the beauty industry, provide their products to opinion leaders for review and further “instruction” of their subscribers. Maria Paula Fernandez does not see anything shameful in this. Observing the experience of bloggers, subscribers begin to acquire a kind of crypto-education and disseminate the information through the word of mouth. Thus, the crypto-community grows.
The most successful bloggers over time can count on sponsorship from one or another crypto company.
For example, the podcaster Marty Bent, whose show is now funded by Unchained Capital and Square, the developer of Cash App, witnessed this scenario. The latter, by the way, in addition to Bent sponsor also podcast Joe Rogan and rapper Lil B.
Many other large companies, including the Kraken exchange, have resorted to this strategy. They are just as interested in sponsoring reputable content creators who promote products among loyal subscribers. The U.S. exchange sponsors the Reckless VR crypto start-up, founded by Udi Wertheimer for crypto-conferences in virtual reality, and the famous podcast Peter McCormack, who launched his own media brand Defiance last year. Having started his career as a hobby, McCormack turned it into a business of his life, thanks to which he earned about $1 million for 2019.
With all this, working with bloggers is a great opportunity to enter foreign markets. This is understood at Crypto.com, where they use opinion leaders to attract the Russian-speaking and Turkish-speaking community. Does this approach give a result? Judge for yourself: over the past six months, the number of startup users has doubled and currently stands at more than 2 million people.
Referral Bonuses and MLM MarketingThe development of products within the community often turns into MLM marketing strategies, which require the presence of referral bonuses and bonuses “in depth” — favorite schemes of cosmetic brands. They use a multi-level reward system for attracting partners, where you can usually get a bonus not only for personally invited, but also for “friends of friends and their friends”. Thus, opinion leaders who distribute crypto products often receive a portion of the funds that people invited by them will pay for the product / service.
The relevance and effectiveness of the trend is confirmed by the fact that these methods are not shy to use not only crypto start-ups, but also top cryptocurrency companies, widely known throughout the industry. A prime example is SatoshiLabs, a company that manufactures and distributes Trezor wallets. The head of communications, Iva Fizerova, confirmed that she is actively resorting to “affiliate marketing” with bloggers as an alternative to paying them for direct advertising.
No less vivid examples are the largest crypto exchanges Binance and Gemini, which managed to succeed not without the help of referral systems copied from the multi-level marketing campaigns Avon and Mary Kay, which they have been using for decades.
Instagram blogger Chjango Unchained has been earning good bonuses for several months running after posting a referral link to Gemini on her profile. When her subscribers register on the exchange and buy cryptocurrencies worth more than $100, she receives $10 in BTC. According to her, she is doing a good deed. The blogger wants people who are interested in her opinion on digital money to start their crypto path on Gemini, and not, for example, on Coinbase, because the latter charges “crazy commissions”.
Referral system bonuses are a typical phenomenon for many crypto companies, and successful bloggers are happy to use this. A prime example is Michael Gu, known by the pseudonym Boxmining. It has been distributing information about digital money since 2012, having gathered an audience of more than 200,000 subscribers on YouTube and more than 3,500 participants in Telegram chat during this time.
Despite the fact that the manufacturer of hardware wallets Ledger does not sponsor its activities, it places referral links in the video descriptions and collects voluntary donations from subscribers. As you might guess, he feels rather well. At the same time, he emphasized that user activity during the coronavirus pandemic is only growing, especially after YouTube began to put sticks in the wheels of the creators of crypto-content.
Gifts, contests and sweepstakesMaking a small gift is a great way to introduce an audience to a new product. In the cryptocurrency market, this has long been relevant.
Coin creators eagerly carry out airdrops and bounty campaigns, allowing the crypto community to test the new coin. A similar approach is popular in the beauty industry. Samplers of perfumes and branded magazines with smells have led many girls to buy full-fledged versions of the fragrance.
In addition to the cryptocurrency developers themselves, a similar approach is also used by cryptocompanies of a different direction, which cannot conduct airdrops due to their technical features (for example, this is true for manufacturers of hardware wallets). Therefore, they organize more classic contests and sweepstakes. For example, they play a wallet for reposting on social networks or videos published on YouTube.
It is noteworthy that cryptobrands in this area are even more active than cosmetics manufacturers. They work not only with trusted bloggers with many subscribers, but also help to become less “untwisted” users. Therefore, they periodically assist them in organizing draws in order to attract subscribers who could potentially become new customers.
Iva Fizerova from SatoshiLabs confirmed that Trezor manufacturers periodically help users attract new followers through the distribution of gifts. Moreover, this approach brings excellent results. By working with the community this way, they have managed to sell hundreds of thousands of wallets. But most importantly, a reputation of the brand has formed around the product, warmly received by the audience. And this effect is so strong that the company simply does not see the point in spending money on traditional expensive advertising.
Most importantly, despite all the problems of 2020, including the coronavirus pandemic, which seriously hit the global economy and, accordingly, people’s wallets, demand for products did not fall. This approach remains effective, while the percentage of successful conversions in traditional advertising has probably decreased. Fizerova noted that over the past three months they have recorded a steady increase in demand for goods. Moreover, they even had to solve delivery problems, if only the buyers got the desired devices in a timely manner.
A similar approach and results are observed with other manufacturers of hardware wallets. Thus, Rodolfo Novak, co-founder of Coinkite, confirmed the growth in demand for products, despite the pandemic. Working with the community is their main marketing strategy, because it really gives results. Over the past three years, they donated about 50 wallets to YouTube reviewers. Novak is proud that their “users help other users.” According to him, this approach allows you to sell products at a lower price, since the cost of goods does not include high costs for familiar marketing campaigns.
Are marketing strategies effective? More thanThe cryptocurrency market relies on marketing strategies that have established themselves in the beauty industry, which in the new field are no less effective. Maximum performance is achieved with a killer combination of all three of the above methods. It’s about when the founders of cryptocompanies themselves become opinion leaders. Just look at Changpen Zhao, the head of Binance, or Justin Sun, the project manager of TRON. Both entrepreneurs are bloggers with a huge army of subscribers and are personally engaged in the promotion of their brands, regularly rewarding their audience with pleasant gifts.
It’s easy to guess why industry leaders rely mainly on this type of marketing. Advertising products in the traditional way is expensive, especially for startups, behind which there are still no attractive products with a good reputation. But more importantly, crypto products are quite complex in themselves, so they often need detailed explanations, which are difficult to implement in the framework of traditional advertising. Agree that selling a bottle of Fanta with a new taste is much easier than a hardware cryptocurrency wallet, especially since most people don’t understand what it is.
On top of that, regular advertising is complicated by the fact that media giants regularly block crypto content.
In such a situation, marketing borrowed from the beauty industry seems to be the most acceptable and most effective option. By focusing their marketing budgets on opinion leaders and working with the community, cryptocompanies achieve the desired result, even taking into account the coronavirus pandemic. The crypto community is getting bigger and stronger every day. But the best part is that this growth cannot be stopped.

1. What is Bitcoin (BTC)?
2. Bitcoin’s core featuresFor a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.
Unspent Transaction Output (UTXO) modelA UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
Nakamoto consensusIn the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.
Block productionThe Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.
Block time and mining difficultyBlock time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.
What are orphan blocks?In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.
3. Bitcoin’s additional features
Segregated Witness (SegWit)Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.
Lightning NetworkLightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.
Schnorr Signature upgrade proposalElliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.
4. Economics and supply distributionThe Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Version 1.3.0 is a powerful update to TkeySpace that our team has been carefully preparing. since version 1.2.0, we have been laying the foundation for implementing new features that are already available in the current version.
Who cares about the security and privacy of their assets is an update for you.
TkeySpace — was designed to give You full control over your digital assets while maintaining an exceptional level of security, which is why there is no personal data in the wallet: phone number, the email address that could be compromised by hackers — no identity checks and other hassles, just securely save the backup phrase consisting of 12 words.
Briefly about the TkeySpace 1.3.0 update :
Code optimization and switching to AndroidXA lot of work has been done on optimizing the code to speed up the application, improving the logic, synchronization speed, calculating the hash of cryptocurrencies, and successfully switching to AndroidX.
New section: Privacy
TORStarting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies.
Tor is a powerful privacy feature for those who own large assets or live in places where the Internet is heavily censored.
Tor technology provides protection against traffic analysis mechanisms that compromise not only Internet privacy, but also the confidentiality of trade secrets, business contacts, and communications in General.When you enable TOR settings, all outgoing traffic from the wallet will be encrypted and routed through an anonymous network of servers, periodically forming a chain through the Tor network, which uses multi-level encryption, effectively hiding any information about the sender: location, IP address, and other data.
This means that if your provider blocks the connection, you can rest easy — after all, by running this function, you will get an encrypted connection to the network without restrictions.
In TOR mode, the wallet may work noticeably slower and in some cases, there may be problems with the network, due to encryption, some blockchain browsers may temporarily not work. However, TOR encryption is very important when Internet providers completely block traffic and switching to this mode, you get complete freedom and no blocks for transactions.
Confidentiality of transactions (the Blockchain transaction)The wallet can change the model of a standard transaction, mixing inputs and outputs, making it difficult to identify certain cryptocurrencies. In the current update, you can select one of several modes for the transaction privacy level: deterministic lexicographic sorting or shuffle mode.
Mode: Lexicographic indexingImplemented deterministic lexicographic sorting using hashes of previous transactions and output indexes for sorting transaction input data, as well as values and scriptPubKeys for sorting transaction output data;
We understand that information must remain confidential not only in the interests of consumers but also in higher orders, financial systems must be kept secret to prevent fraud. One way to address these privacy shortcomings is to randomize the order of inputs and outputs.
Lexicographic ordering is a comparison algorithm used to sort two sets based on their Cartesian order within their common superset. Lexicographic order is also often referred to as alphabetical order or dictionary order. The hashes of previous transactions (in reverse byte order) are sorted in ascending order, lexicographically.In the case of two matching transaction hashes, the corresponding previous output indexes will be compared by their integer value in ascending order. If the previous output indexes match, the input data is considered equal.
Shuffle Mode: mixing (random indexing)To learn more about how “shuffle mode” works, we will first analyze the mechanisms using the example of a classic transaction. Current balance Of your wallet: 100 TKEY, coins are stored at different addresses:
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
Addresses in the blockchain are identifiers that you use to send cryptocurrency to another person or to receive digital currency.In a classic transaction, if you need to send, for example, 19 TKEY — 100 TKEY will be sent to the network for “melting” coins, 19 TKEY will be sent to the Recipient, and ~80.9 TKEY will return to the newly generated address for “change” in your wallet.
In the blockchain explorer, you will see the transaction amount in the amount of 100 TKEY, where 80.99999679 TKEY is your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee. Thus, in the blockchain search engine, most of your balance is shown in the transaction.
How does the shuffle mode work?Let’s look at a similar example: you have 100 TKEY on your balance, and you need to send 19 TKEY.
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
You send 19 TKEY, the system analyzes all your addresses and balances on them and selects the most suitable ones for the transaction. To send 19 TKEY, the miners will be given coins with x2. Addresses, for a total of 20 TKEY. Of these, 19 TKEY will be sent to the recipient, and 0.99999679 TKEY will be returned to Your new address as change minus the transaction fee.
In the blockchain explorer, you will see the transaction amount in the amount of 20 TKEY, where 0.99999679 TKEY is Your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee.
The shuffle mode has a cumulative effect. with each new transaction, delivery Addresses will be created and the selection of debit addresses/s that are most suitable for the transaction will change. Thus, if you store 1,000,000 TKEY in your wallet and want to send 1 TKEY to the recipient, the transaction amount will not display most of your balance but will select 1 or more addresses for the transaction.
Selecting the recovery method for each digital currency (Blockchain restore)Now you can choose the recovery method for each currency: API + Blockchain or blockchain.
Note: This is not a syncing process, but rather the choice of a recovery method for your wallet. Syncing takes place with the blockchain — regardless of the method you choose.https://preview.redd.it/gxsssuxrttx41.png?width=1080&format=png&auto=webp&s=cd9fe383618dda0e990e86485652ff95652a8481
What are the differences between recovery methods?
API + BlockchainIn order not to load the entire history of the blockchain, i.e. block and transaction headers, the API helps you quickly get point information about previous transactions. For example, If your transactions are located in block 67325 and block 71775, the API will indicate to the node the necessary points for restoring Your balance, which will speed up the “recovery” process.
As soon as the information is received, communication with the peers takes place and synchronization begins from the control point, then from this moment, all subsequent block loading is carried out through the blockchain. This method allows you to quickly restore Your existing wallet.
‘’-’’ The API server may fail.
BlockchainThis method loads all block headers (block headers + Merkle) starting from the BIP44 checkpoint and manually validates transactions.
‘’+’’ It always works and is decentralized. ‘’-’’ Loading the entire blockchain may take a long time.
Why do I need to switch the recovery method?If when creating a wallet or restoring it, a notification (!) lights up in red near the selected cryptocurrency, then most likely the API has failed, so go to Settings — Security Center — Privacy — Blockchain Restore — switch to Blockchain. Syncing will be successful.
Selecting the address formatYou can choose the address format not only for Bitcoin but also for Litecoin. Legacy, SegWit, Native SegWit. Go to Settings — Manage Wallets — Address Format.
Working at the code level
Enhanced validation of transactions and blocks in the networkDue to the increased complexity in the Tkeycoin network, we have implemented enhanced validation of the tkeycoin consensus algorithm, and this algorithm is also available for other cryptocurrencies.
What is the advantage of the enhanced validation algorithm for the userFirst, the name itself speaks for itself — it increases the security of the network, and second, by implementing the function — we have accelerated the work of the TkeySpace blockchain node, the application consumes even fewer resources than before.
High complexity is converted to 3 bytes, which ensures fast code processing and the least resource consumption on your device.
SynchronizationThe synchronization process has been upgraded. Node addresses are added to the local storage, and instant synchronization with nodes occurs when you log in again.
Checking for double-spendingTkeySpace eliminates “double-spending” in blockchains, which is very valuable in the Bitcoin and Litecoin networks.
For example, using another application, you may be sent a fake transaction, and the funds will eventually disappear from the network and your wallet because this feature is almost absent in most applications.Using TkeySpace — you are 100% sure that your funds are safe and protected from fraudulent transactions in the form of “fake” transactions.
The bloom filter to check for nodesAll nodes are checked through the bloom filter. This allows you to exclude fraudulent nodes that try to connect to the network as real nodes of a particular blockchain.
In practice, this verification is not available in applications, Tkeycoin — decided to follow a new trend and change the stereotypes, so new features such as node verification using the bloom filter and double-spending verification are a kind of innovation in applications that work with cryptocurrencies.
Updating the Binance and Ethereum librariesUpdated Binance and Ethereum libraries for interaction with the TOR network.
Function — to hide the balanceThis function allows you to hide the entire balance from the main screen.
Advanced currency charts and charts without authenticationDetailed market statistics are available, including volumes, both for 1 day and several years. Select the period of interest: 1 day, 7 days, 1 month, 3 months, 6 months, 1 year, 2 years.
In version 1.3.0, you can access charts without authentication. You can monitor the cryptocurrency exchange rate without even logging in to the app. If you have a pin code for logging in, when you open the app, swipe to the left and you will see a list of currencies.
NewsIn the market data section — in the tkeyspace added a section with current news of the cryptocurrency market.
Blockchain Explorer for TkeycoinTransaction verification for Tkeycoin is now available directly in the app.
Independent Commission entry for BitcoinTaking into account the large volume of the Bitcoin network, we have implemented independent Commission entry — you can specify any Commission amount.
For other currencies, smart Commission calculation is enabled based on data from the network. The network independently regulates the most profitable Commission for the sender.

How do I update TkeySpace to version 1.3.0?

If you’ve ever heard the word cryptocurrency, then you’ve probably heard about the mining as well. If you still don’t know what cryptocurrency mining is and about profitable, keep reading!
In order to understand crypto mining, you need to fully understand what a cryptocurrency is first. Unlike traditional currencies (aka fiat currency), a cryptocurrency is a digital asset that works in a decentralized way; it does not require a bank or a third-party to operate. Someone can send someone else a cryptocurrency directly without any third-party involved.
The first ever cryptocurrency created was Bitcoin.
Every single cryptocurrency has a blockchain, which is an immutable digital ledger. A single transaction is recorded on the blockchain permanently, which no one can edit or delete it randomly.
A blockchain works by incentivizing miners to confirm the authenticity of each transaction. A person who confirmed the authenticity of the transaction, get the cryptocurrency as a reward.
Since the cryptocurrencies are based on cryptography, the miners need to solve extremely complicated mathematical problems to verify each transaction. They are incentivized to do it because they are rewarded for it.
Anyone can participate in mining from anywhere in the world as long as they have a computer. When the number of miners increases, it allows cryptocurrencies to be more secure. Even if an attacker would want to attack the blockchain network, somehow, an attacker needs to know 51% or more miners. Since the miners are spread around the world, this task is close to impossible and most likely not economically viable.
Types of Crypto MiningBitcoin was the first cryptocurrency to introduce the Proof-of-Work (PoW) consensus algorithm, where users have to solve complex mathematical problems in order to process transactions and secure the whole network.
Bitcoin was quite easy to mine at first, and you could do it with your CPU, there was no need for special equipment, and the rewards were huge. However, today, Bitcoin’s mining difficulty has increased considerably, and users need specialized and expensive equipment to mine it.
There are four main types of mining when it comes to the PoW algorithm. There is a CPU, GPU, ASIC, and Cloud mining.
The first three are essentially the same, but they use different parts of your computer. There are some cryptocurrencies specifically created to be mined only through CPU and to be ASIC resistant. Other cryptocurrencies can be mined through all three methods.
Cloud mining, on the other hand, is a process where a user basically pays to rent out a mining machine somewhere else. You don’t have to buy the equipment physically but it is wise to carry out due diligence and research into who and what you are paying for.
Proof of Stake ‘Mining’With the introduction of the Proof-of-Stake (PoS) consensus algorithm, cryptocurrency mining changed forever. In this case, users don’t have to solve computationally intensive puzzles. In PoS-based cryptocurrencies, the creator of blocks is chosen via random selection or wealth.
Validators in the PoS consensus have to lock up some of their coins as a ‘stake’ and will get rewarded for it.
There are many benefits over the traditional PoW like lower cost and more energy efficiency. Additionally, because PoS encourages users to hold the coin in the wallet, it stabilizes the price a bit more than conventional cryptocurrencies.
Today, you can find plenty of exchanges that support staking, including the most popular exchange, Binance. The safest option, however, is always going to be staking using your own private wallet.
Proof of Formulation ‘Mining’FLETA has developed the most innovative and newest consensus algorithms known as Proof-of-Formulation (PoF).
This PoF consensus algorithm uses something called the ‘Synchronization Group’, which allows all of the miners to mine in an orderly manner. The generating block time only takes 0.5 seconds, and the observer node checks the irregular blocks in real-time, which prevents the fork and double-spending. Furthermore, FLETA’s PoF algorithm is currently undergoing the patent process through the United States Patent Office (Application Number: 62717695).
The users can easily create a FLETA formulator through the official FLETA wallet. The minimum amount to create a single Formulator is 200,000 FLETA. The blockchain network is operated by FLETA and requires a 6-core CPU or higher.
As you created at least four Formulators, you will be able to upgrade it, which allows you to get 1.3 times more rewards.
Besides creating a Formulator, users can contribute to mining with a minimum amount of 100 FLETA.
ConclusionToday, various mining methods exist, each with their pros and cons. However, cryptocurrency miners are still craving more convenient (and less costly) ways to earn rewards.
FLETA’s Proof-of-Formulation consensus is not only fast, but it is also highly secure the added layer of protection between observer nodes, formulator, and the synchronization group.
With plenty more to come, in terms of DApp development, games and partnerships, FLETA’s PoF is increasingly becoming the preferred consensus of many developers due to the speed, security and convenience of the platform.
According to the Bitcoin Glossary, a Double Spend is a transaction that uses the same input as an already broadcast transaction.. In simple day to day terms, it means spending the same amount of money twice. Double spending is a phenomenon that’s not directly related to Bitcoin, but to all digital monetary systems.In fact, Bitcoin is what it is today because it managed to solve the double ... Double Spending Problem and Cryptocurrencies. The main problem in creating a stable system of decentralized payments was the ability to copy payment transactions, which causes the risk of re-spending funds. Centralized payment systems prevent the re-transfer of funds by the presence of a monitoring server that checks all transactions using a specific mechanism. Double spending is a kind of re ... While Bitcoin in Bit Gold share a similar vision, there are distinctive differences between their protocols. More specifically, Bit Gold couldn't be fully deployed as it couldn't address the famous double-spending problem. Double-spending. Essentially, double-spending refers to the process of spending the same amount of money twice. In physical ... Double-spending is a potential issue in a digital cash system where the same funds are spent to two recipients at the same time. Without any adequate countermeasures, a protocol that doesn’t resolve the problem is fundamentally undermined – users have no way to verify that the funds they’ve received have not already been spent elsewhere. Double-spending is one of the most prevalent concerns in using digital currencies, most notably with cryptocurrencies like bitcoin (BTC) and thousands of others. It’s defined as being “the risk that a digital currency can be spent twice.” While blockchain technology is undeniably complicated, individuals who are sufficiently aware and have high levels of understanding about these kinds ... 3. RBF – “Legit” Double Spending. One form of “legit” double spending is Replace By Fee or RBF for short. RBF is a function embedded in certain Bitcoin wallets (e.g. Electrum) that allows you to rebroadcast a transaction that is still unconfirmed, in order to get it confirmed faster.. In some cases, Bitcoin transactions are sent with a network fee that is too small to incentivize ... The Problem of Double Spending: How did Bitcoin Solve it? The idea of digital money has been around for a long period of time now, and it did not originate 10 years ago when Bitcoin first emerged. However, all previous attempts to come up with a product that we now know as cryptocurrencies have failed for one simple reason — double spending. In 2008, Bitcoin was introduced and it became the most widely used and accepted digital currency. The Bitcoin was a success due to the fact that it had solved problems which its predecessor could not solve. One of these issues was a double spending. Let’s see how Bitcoin has solved this problem. Double Spending Binance is a blockchain ecosystem comprised of Exchange, Labs, Launchpad, and Info. Binance Exchange is one of the fastest growing and most popular cryptocurrency exchanges in the world. Founded by a team of fintech and crypto experts — it is capable of processing more than 1.4 million orders per second, making it one of the fastest exchanges in the world. The platform focuses on security ... Digitales Geld stellt Nutzer vor ein Problem. Es kann wesentlich leichter kopiert und damit "doppelt" ausgegeben werden. Den Vorgang bezeichnet man als Double Spending. Bis zur Einführung von Bitcoin im Jahr 2009 hatten digitale Geldeinheiten keinen hohen Stellenwert in der Netzgemeinschaft. Sie wurden in jedem Fall von einer zentralen Instanz ...
