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.

This way, we can ask by symmetry: if a certainty exists that when emission increases, inflation increases, the reverse should happen when emission becomes negative, obtaining negative inflation. Nonetheless, we know this happens: prices have an easier time increasing and a lot of rigidity decreasing. So the identity between emission and inflation is not like that, deflation almost never exists and the price movement rhythm cannot be controlled remotely only with money quantity. There is no mechanical relationship between one thing and the other.First, the low hanging fruit: deflation is not that uncommon, for those of you that live in US and Europe it should be obvious given the difficulties central banks had to achieve their targets, but even Argentina has seen deflation during its depression 20 years ago.
Inflation occurs when the average level of prices increases. Individual price increases in and of themselves do not equal inflation, but an overall pattern of price increases does. The price level observed in the economy is that which leads the quantity of money supplied to equal the quantity of money demanded. The quantity of money supplied is largely controlled by the [central bank]. When the supply of money increases or decreases, the price level must adjust to equate the quantity of money demanded throughout the economy with the quantity of money supplied. The quantity of money demanded depends not only on the price level but also on the level of real income, as measured by real gross domestic product (GDP), and a variety of other factors including the level of interest rates and technological advances such as the invention of automated teller machines. Money demand is widely thought to increase roughly proportionally with the price level and with real income. That is, if prices go up by 10 percent, or if real income increases by 10 percent, empirical evidence suggests people want to hold 10 percent more money. When the money supply grows faster than the money demand associated with rising real incomes and other factors, the price level must rise to equate supply and demand. That is, inflation occurs. This situation is often referred to as too many dollars chasing too few goods. Note that this theory does not predict that any money-supply growth will lead to inflation—only that part of money supply growth that exceeds the increase in money demand associated with rising real GDP (holding the other factors constant).So it's not mere emission, but money supply growing faster than money demand which we should consider. So negative emission is not necessary condition for deflation in this theory.
In Argentina we know that the main determinant of inflation is dollar price increases. On that, economic concentration of key markets, utility price adjustments, fuel prices, distributive struggles, external commodity values, expectatives, productive disequilibrium, world interest rates, the economic cycle, stationality and external sector restrictions act on it too.For the first paragraph, one could try to run econometric tests for all those variables, at least from my layman perspective. But given that it doesn't pass the smell test (has any country used that in its favor ignoring monetary policy? Also, I have shown there is at least some evidence for the money-price relationship before), I'll try to address what happened in Macri's government and if monetarism (or at least some reasonable extension of it) cannot account for it.
Let's see a simple example: during Macri's government since mid 2017 to 2019 emission was practically null, but when in 2018 the dollar value doubled, inflation doubled too (it went from 24% to 48% in 2018) and it went up again a year later. We see here that the empirical validity of monetarist theory was absent.
Monetarism apologists answer, when confronted with those grave empirical problems that happen in "serious countries", that the population "trusts" their monetary authorities, even increasing the money demand in those place despite the emission. Curious, though, it's an appeal to "trust" implying that the relationship between emission and inflation is not objective, but subjective and cultural: an appreciation that abandons mechanicism and the basic certainty of monetarism, because evaluations and diagnostics, many times ideologic, contextual or historical intervene..That's just a restatement of applying rational expectations to central bank operations. I don't see a problem with that. Rational expectations is not magic, it's an assessment of future earnings by economic actors. Humans may not 100% rational but central banking somehow works on many countries. You cannot just say that people are ideologues and let it at that. What's your model?
The last question to monetarism allows to recognize it something: effectively we can think on a type of vinculation between emission and inflation in extreme conditions. That means, with no monetary rule, no government has the need of taxes but instead can emit and spend all it needs without consequence. We know it's not like that: no government can print infinitely without undesirable effects.Ok, good disclaimer, but given what he wrote before, what's the mechanism which causes money printing to be inflationary at some point? It was rejected before but now it seems that it exists. What was even the point of the article?
Now, the problem is thinking monetarism on its extremes: without emission we have inflation sometimes, on others we have no inflation with emission, we know that if we have negative emission that doesn't guarantees us negative inflation, but that if emission is radically uncontrolled there will economic effects.As I wrote above, that's not what monetarism (even on it's simpler form) says, nor a consequence of it. You can see some deviations in low inflation environment but it's not really Argentina's current situation.
Let's add other problems: the elastic question between money and prices is not evident. Neither is time lags in which can work or be neutral. So the question is the limit cases for monetarism which has some reason but some difficulty in explaining them: by which and it what moments rules work and in which it doesn't.I find the time lag thing to be a red herring. You can observe empirically and not having a proper short/middle run model doesn't invalidate QTOM in the long run. While it may be that increasing interest rates or freezing MB is not effective, that's less a problem of the theory and more a problem of policy implementation.

The DFINITY blockchain computer provides a secure, performant and flexible consensus mechanism. At its core, DFINITY contains a decentralized randomness beacon, which acts as a verifiable random function (VRF) that produces a stream of outputs over time. The novel technique behind the beacon relies on the existence of a unique-deterministic, non-interactive, DKG-friendly threshold signatures scheme. The only known examples of such a scheme are pairing-based and derived from BLS.
The DFINITY blockchain is layered on top of the DFINITY beacon and uses the beacon as its source of randomness for leader selection and leader ranking. A “weight” is attributed to a chain based on the ranks of the leaders who propose the blocks in the chain, and that weight is used to select between competing chains. The DFINITY blockchain is layered on top of the DFINITY beacon and uses the beacon as its source of randomness for leader selection and leader ranking blockchain is further hardened by a notarization process which dramatically improves the time to finality and eliminates the nothing-at-stake and selfish mining attacks.
DFINITY consensus algorithm is made to scale through continuous quorum selections driven by the random beacon. In practice, DFINITY achieves block times of a few seconds and transaction finality after only two confirmations. The system gracefully handles temporary losses of network synchrony including network splits, while it is provably secure under synchrony.
1.INTRODUCTIONDFINITY is building a new kind of public decentralized cloud computing resource. The company’s platform uses blockchain technology which is aimed at building a new kind of public decentralized cloud computing resource with unlimited capacity, performance and algorithmic governance shared by the world, with the capability to power autonomous self-updating software systems, enabling organizations to design and deploy custom-tailored cloud computing projects, thereby reducing enterprise IT system costs by 90%.
DFINITY aims to explore new territory and prove that the blockchain opportunity is far broader and deeper than anyone has hitherto realized, unlocking the opportunity with powerful new crypto.
Although a standalone project, DFINITY is not maximalist minded and is a great supporter of Ethereum.
The DFINITY blockchain computer provides a secure, performant and flexible consensus mechanism. At its core, DFINITY contains a decentralized randomness beacon, which acts as a verifiable random function (VRF) that produces a stream of outputs over time. The novel technique behind the beacon relies on the existence of a unique-deterministic, non-interactive, DKG-friendly threshold signatures scheme. The only known examples of such a scheme are pairing-based and derived from BLS.
DFINITY’s consensus mechanism has four layers: notary (provides fast finality guarantees to clients and external observers), blockchain (builds a blockchain from validated transactions via the Probabilistic Slot Protocol driven by the random beacon), random beacon (provides the source of randomness for all higher layers like smart contract applications), and identity (provides a registry of all clients).
DFINITY’s consensus mechanism has four layers
Figure1: DFINITY’s consensus mechanism layers
1. Identity layer:
Active participants in the DFINITY Network are called clients. Where clients are registered with permanent identities under a pseudonym. Moreover, DFINITY supports open membership by providing a protocol for registering new clients by depositing a stake with an insurance period. This is the responsibility of the first layer.
2. Random Beacon layer:
Provides the source of randomness (VRF) for all higher layers including ap- plications (smart contracts). The random beacon in the second layer is an unbiasable, verifiable random function (VRF) that is produced jointly by registered clients. Each random output of the VRF is unpredictable by anyone until just before it becomes avail- able to everyone. This is a key technology of the DFINITY system, which relies on a threshold signature scheme with the properties of uniqueness and non-interactivity.
3. Blockchain layer:
The third layer deploys the “probabilistic slot protocol” (PSP). This protocol ranks the clients for each height of the chain, in an order that is derived determin- istically from the unbiased output of the random beacon for that height. A weight is then assigned to block proposals based on the proposer’s rank such that blocks from clients at the top of the list receive a higher weight. Forks are resolved by giving favor to the “heaviest” chain in terms of accumulated block weight — quite sim- ilar to how traditional proof-of-work consensus is based on the highest accumulated amount of work.
The first advantage of the PSP protocol is that the ranking is available instantaneously, which allows for a predictable, constant block time. The second advantage is that there is always a single highest-ranked client, which allows for a homogenous network bandwidth utilization. Instead, a race between clients would favor a usage in bursts.
4. Notarization layer:
Provides fast finality guarantees to clients and external observers. DFINITY deploys the novel technique of block notarization in its fourth layer to speed up finality. A notarization is a threshold signature under a block created jointly by registered clients. Only notarized blocks can be included in a chain. Of all RSA-based alternatives exist but suffer from an impracticality of setting up the thresh- old keys without a trusted dealer.
DFINITY achieves its high speed and short block times exactly because notarization is not full consensus.
DFINITY does not suffer from selfish mining attack or a problem nothing at stake because the authentication step is impossible for the opponent to build and maintain a series of linked and trusted blocks in secret.
DFINITY’s consensus is designed to operate on a network of millions of clients. To en- able scalability to this extent, the random beacon and notarization protocols are designed such as that they can be safely and efficiently delegated to a committee
1.1 OVERVIEW ABOUT DFINITYDFINITY is a blockchain-based cloud-computing project that aims to develop an open, public network, referred to as the “internet computer,” to host the next generation of software and data. and it is a decentralized and non-proprietary network to run the next generation of mega-applications. It dubbed this public network “Cloud 3.0”.
DFINITY is a third generation virtual blockchain network that sets out to function as an “intelligent decentralised cloud,”¹ strongly focused on delivering a viable corporate cloud solution. The DFINITY project is overseen, supported and promoted by DFINITY Stiftung a not-for-profit foundation based in Zug, Switzerland.
DFINITY is a decentralized network design whose protocols generate a reliable “virtual blockchain computer” running on top of a peer-to-peer network upon which software can be installed and can operate in the tamperproof mode of smart contracts.
DFINITY introduces algorithmic governance in the form of a “Blockchain Nervous System” that can protect users from attacks and help restart broken systems, dynamically optimize network security and efficiency, upgrade the protocol and mitigate misuse of the platform, for example by those wishing to run illegal or immoral systems.
DFINITY is an Ethereum-compatible smart contract platform that is implementing some revolutionary ideas to address blockchain performance, scaling, and governance. Whereas
DFINITY could pose a credible threat to Ethereum’s extinction, the project is pursuing a coevolutionary strategy by contributing funding and effort to Ethereum projects and freely offering their technology to Ethereum for adoption. DFINITY has labeled itself Ethereum’s “crazy sister” to express it’s close genetic resemblance to Ethereum, differentiated by its obsession with performance and neuron-inspired governance model.
Dfinity raised $61 million from Andreesen Horowitz and Polychain Capital in a February 2018 funding round. At the time, Dfinity said it wanted to create an “internet computer” to cut the costs of running cloud-based business applications. A further $102 million funding round in August 2018 brought the project’s total funding to $195 million.
In May 2018, Dfinity announced plans to distribute around $35 million worth of Dfinity tokens in an airdrop. It was part of the company’s plan to create a “Cloud 3.0.” Because of regulatory concerns, none of the tokens went to US residents.
DFINITY be broadening and strengthening the EVM ecosystem by giving applications a choice of platforms with different characteristics. However, if DFINITY succeeds in delivering a fully EVM-compatible smart contract platform with higher transaction throughput, faster confirmation times, and governance mechanisms that can resolve public disputes without causing community splits, then it will represent a clearly superior choice for deploying new applications and, as its network effects grow, an attractive place to bring existing ones. Of course the challenge for DFINITY will be to deliver on these promises while meeting the security demands of a public chain with significant value at risk.
1.1.1 DFINITY FUTURE
1.1.2 DFINITY’S VISIONDFINITY’s vision is its new internet infrastructure can support a wide variety of end-user and enterprise applications. Social media, messaging, search, storage, and peer-to-peer Internet interactions are all examples of functionalities that DFINITY plans to host atop its public Web 3.0 cloud-like computing resource. In order to provide the transaction and data capacity necessary to support this ambitious vision, DFINITY features a unique consensus model (dubbed Threshold Relay) and algorithmic governance via its Blockchain Nervous System (BNS) — sometimes also referred to as the Network Nervous System or NNS.
1.2 DFINITY COMMUNITYThe DFINITY community brings people and organizations together to learn and collaborate on products that help steward the next-generation of internet software and services. The Internet Computer allows developers to take on the monopolization of the internet, and return the internet back to its free and open roots. We’re committed to connecting those who believe the same through our events, content, and discussions.

Dfinity launches an open source platform aimed at the social networking giants
2.DFINITY TECHNOLOGYDfinity is building what it calls the internet computer, a decentralized technology spread across a network of independent data centers that allows software to run anywhere on the internet rather than in server farms that are increasingly controlled by large firms, such as Amazon Web Services or Google Cloud. This week Dfinity is releasing its software to third-party developers, who it hopes will start making the internet computer’s killer apps. It is planning a public release later this year.
At its core, the DFINITY consensus mechanism is a variation of the Proof of Stake (PoS) model, but offers an alternative to traditional Proof of Work (PoW) and delegated PoS (dPoS) networks. Threshold Relay intends to strike a balance between inefficiencies of decentralized PoW blockchains (generally characterized by slow block times) and the less robust game theory involved in vote delegation (as seen in dPoS blockchains). In DFINITY, a committee of “miners” is randomly selected to add a new block to the chain. An individual miner’s probability of being elected to the committee proposing and computing the next block (or blocks) is proportional to the number of dfinities the miner has staked on the network. Further, a “weight” is attributed to a DFINITY chain based on the ranks of the miners who propose blocks in the chain, and that weight is used to choose between competing chains (i.e. resolve chain forks).
A decentralized random beacon manages the random selection process of temporary block producers. This beacon is a Variable Random Function (VRF), which is a pseudo-random function that provides publicly verifiable proofs of its outputs’ correctness. A core component of the random beacon is the use of Boneh-Lynn-Shacham (BLS) signatures. By leveraging the BLS signature scheme, the DFINITY protocol ensures no actor in the network can determine the outcome of the next random assignment.
Dfinity is introducing a new standard, which it calls the internet computer protocol (ICP). These new rules let developers move software around the internet as well as data. All software needs computers to run on, but with ICP the computers could be anywhere. Instead of running on a dedicated server in Google Cloud, for example, the software would have no fixed physical address, moving between servers owned by independent data centers around the world. “Conceptually, it’s kind of running everywhere,” says Dfinity engineering manager Stanley Jones.
DFINITY also features a native programming language, called ActorScript (name may be subject to change), and a virtual machine for smart contract creation and execution. The new smart contract language is intended to simplify the management of application state for programmers via an orthogonal persistence environment (which means active programs are
not required to retrieve or save their state). All ActorScript contracts are eventually compiled down to WebAssembly instructions so the DFINITY virtual machine layer can execute the logic of applications running on the network. The advantage of using the WebAssembly standard is that all major browsers support it and a variety of programming languages can compile down to Wasm (not just ActorScript).
Dfinity is moving fast. Recently, Dfinity showed off a TikTok clone called CanCan. In January it demoed a LinkedIn-alike called LinkedUp. Neither app is being made public, but they make a convincing case that apps made for the internet computer can rival the real things.
2.1 DFINITY CORE APPLICATIONSThe DFINITY cloud has two core applications:
Whilst conceptually similar to Ethereum, DFINITY employs original and new cryptography methods and protocols (crypto:3) at the network level, in concert with AI and network-fuelled systemic governance (Blockchain Nervous System — BNS) to facilitate Corporate adoption.
DFINITY recognises that different users value different properties and sees itself as more of a fully compatible extension of the Ethereum ecosystem rather than a competitor of the Ethereum network.
In the future, DFINITY hopes that much of their “new crypto might be used within the Ethereum network and are also working hard on shared technology components.”
As the DFINITY project develops over time, the DFINITY Stiftung foundation intends to steadily increase the BNS’ decision-making responsibilities over time, eventually resulting in the dissolution of its own involvement entirely, once the BNS is sufficiently sophisticated.
DFINITY consensus mechanism is a heavily optimized proof of stake (PoS) model. It places a strong emphasis on transaction finality through implementing a Threshold Relay technique in conjunction with the BLS signature scheme and a notarization method to address many of the problems associated with PoS consensus.
2.2 THRESHOLD RELAYAs a public cloud computing resource, DFINITY targets business applications by substantially reducing cloud computing costs for IT systems. They aim to achieve this with a highly scalable and powerful network with potentially unlimited capacity. The DFINITY platform is chalk full of innovative designs and features like their Blockchain Nervous System (BNS) for algorithmic governance.
One of the primary components of the platform is its novel Threshold Relay Consensus model from which randomness is produced, driving the other systems that the network depends on to operate effectively. The consensus system was first designed for a permissioned participation model but can be paired with any method of Sybil resistance for an open participation model.
“The Threshold Relay is the mechanism by which Dfinity randomly samples replicas into groups, sets the groups (committees) up for threshold operation, chooses the current committee, and relays from one committee to the next is called the threshold relay.”
Threshold Relay consists of four layers (As mentioned previously):
2.2.1 HOW DOES THRESHOLD RELAY WORK?Threshold Relay produces an endogenous random beacon, and each new value defines random group(s) of clients that may independently try and form into a “threshold group”. The composition of each group is entirely random such that they can intersect and clients can be presented in multiple groups. In DFINITY, each group is comprised of 400 members. When a group is defined, the members attempt to set up a BLS threshold signature system using a distributed key generation protocol. If they are successful within some fixed number of blocks, they then register the public key (“identity”) created for their group on the global blockchain using a special transaction, such that it will become part of the set of active groups in a following “epoch”. The network begins at “genesis” with some number of predefined groups, one of which is nominated to create a signature on some default value. Such signatures are random values — if they were not then the group’s signatures on messages would be predictable and the threshold signature system insecure — and each random value produced thus is used to select a random successor group. This next group then signs the previous random value to produce a new random value and select another group, relaying between groups ad infinitum and producing a sequence of random values.
In a cryptographic threshold signature system a group can produce a signature on a message upon the cooperation of some minimum threshold of its members, which is set to 51% in the DFINITY network. To produce the threshold signature, group members sign the message
individually (here the preceding group’s threshold signature) creating individual “signature shares” that are then broadcast to other group members. The group threshold signature can be constructed upon combination of a sufficient threshold of signature shares. So for example, if the group size is 400, if the threshold is set at 201 any client that collects that many shares will be able to construct the group’s signature on the message. Other group members can validate each signature share, and any client using the group’s public key can validate the single group threshold signature produced by combining them. The magic of the BLS scheme is that it is “unique and deterministic” meaning that from whatever subset of group members the required number of signature shares are collected, the single threshold signature created is always the same and only a single correct value is possible.
Consequently, the sequence of random values produced is entirely deterministic and unmanipulable, and signatures generated by relaying between groups produces a Verifiable Random Function, or VRF. Although the sequence of random values is pre-determined given some set of participating groups, each new random value can only be produced upon the minimal agreement of a threshold of the current group. Conversely, in order for relaying to stall because a random number was not produced, the number of correct processes must be below the threshold. Thresholds are configured so that this is extremely unlikely. For example, if the group size is set to 400, and the threshold is 201, 200 or more of the processes must become faulty to prevent production. If there are 10,000 processes in the network, of which 3,000 are faulty, the probability this will occur is less than 10e-17.
2.3 DFINITY TOKENThe DFINITY blockchain also supports a native token, called dfinities (DFN), which perform multiple roles within the network, including:
Neuron operators can earn Dfinities by participating in network-wide votes, which could be concerning protocol upgrades, a new economic policy, etc. DFN rewards for participating in the governance system are proportional to the number of tokens staked inside a neuron.
2.4 SCALABILITYDFINITY is constantly developing with a structure that separates consensus, validation, and storage into separate layers. The storage layer is divided into multiple strings, each of which is responsible for processing transactions that occur in the fragment state. The verification layer is responsible for combining hashes of all fragments in a Merkle-like structure that results in a global state fractionation that is stored in blocks in the top-level chain.
2.5 DFINITY CONSENSUS ALGORITHMThe single most important aspect of the user experience is certainly the time required before a transaction becomes final. This is not solved by a short block time alone — Dfinity’s team also had to reduce the number of confirmations required to a small constant. DFINITY moreover had to provide a provably secure proof-of-stake algorithm that scales to millions of active participants without compromising any bit on decentralization.
Dfinity soon realized that the key to scalability lay in having an unmanipulable source of randomness available. Hence they built a scalable decentralized random beacon, based on what they call the Threshold Relay technique, right into the foundation of the protocol. This strong foundation drives a scalable and fast consensus layer: On top of the beacon runs a blockchain which utilizes notarization by threshold groups to achieve near-instant finality. Details can be found in the overview paper that we are releasing today.
The roots of the DFINITY consensus mechanism date back to 2014 when thair Chief Scientist, Dominic Williams, started to look for more efficient ways to drive large consensus networks. Since then, much research has gone into the protocol and it took several iterations to reach its current design.
For any practical consensus system the difficulty lies in navigating the tight terrain that one is given between the boundaries imposed by theoretical impossibility-results and practical performance limitations.
The first key milestone was the novel Threshold Relay technique for decentralized, deterministic randomness, which is made possible by certain unique characteristics of the BLS signature system. The next breakthrough was the notarization technique, which allows DFINITY consensus to solve the traditional problems that come with proof-of-stake systems. Getting the security proofs sound was the final step before publication.
DFINITY consensus has made the proper trade-offs between the practical side (realistic threat models and security assumptions) and the theoretical side (provable security). Out came a flexible, tunable algorithm, which we expect will establish itself as the best performing proof-of-stake algorithm. In particular, having the built-in random beacon will prove to be indispensable when building out sharding and scalable validation techniques.
2.6 LINKEDUPThe startup has rather cheekily called this “an open version of LinkedIn,” the Microsoft-owned social network for professionals. Unlike LinkedIn, LinkedUp, which runs on any browser, is not owned or controlled by a corporate entity.
LinkedUp is built on Dfinity’s so-called Internet Computer, its name for the platform it is building to distribute the next generation of software and open internet services.
The software is hosted directly on the internet on a Switzerland-based independent data center, but in the concept of the Internet Computer, it could be hosted at your house or mine. The compute power to run the application LinkedUp, in this case — is coming not from Amazon AWS, Google Cloud or Microsoft Azure, but is instead based on the distributed architecture that Dfinity is building.
Specifically, Dfinity notes that when enterprises and developers run their web apps and enterprise systems on the Internet Computer, the content is decentralized across a minimum of four or a maximum of an unlimited number of nodes in Dfinity’s global network of independent data centers.
Dfinity is an open source for LinkedUp to developers for creating other types of open internet services on the architecture it has built.
“Open Social Network for Professional Profiles” suggests that on Dfinity model one can create “Open WhatsApp”, “Open eBay”, “Open Salesforce” or “Open Facebook”.
The tools include a Canister Software Developer Kit and a simple programming language called Motoko that is optimized for Dfinity’s Internet Computer.
“The Internet Computer is conceived as an alternative to the $3.8 trillion legacy IT stack, and empowers the next generation of developers to build a new breed of tamper-proof enterprise software systems and open internet services. We are democratizing software development,” Williams said. “The Bronze release of the Internet Computer provides developers and enterprises a glimpse into the infinite possibilities of building on the Internet Computer — which also reflects the strength of the Dfinity team we have built so far.”
Dfinity says its “Internet Computer Protocol” allows for a new type of software called autonomous software, which can guarantee permanent APIs that cannot be revoked. When all these open internet services (e.g. open versions of WhatsApp, Facebook, eBay, Salesforce, etc.) are combined with other open software and services it creates “mutual network effects” where everyone benefits.
On 1 November, DFINITY has released 13 new public versions of the SDK, to our second major milestone [at WEF Davos] of demoing a decentralized web app called LinkedUp on the Internet Computer. Subsequent milestones towards the public launch of the Internet Computer will involve:
2.7 WHAT IS MOTOKO?Motoko is a new software language being developed by the DFINITY Foundation, with an accompanying SDK, that is designed to help the broadest possible audience of developers create reliable and maintainable websites, enterprise systems and internet services on the Internet Computer with ease. By developing the Motoko language, the DFINITY Foundation will ensure that a language that is highly optimized for the new environment is available. However, the Internet Computer can support any number of different software frameworks, and the DFINITY Foundation is also working on SDKs that support the Rust and C languages. Eventually, it is expected there will be many different SDKs that target the Internet Computer.
