A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.

CosmosCosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.

PolkadotPolkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.

AvalancheAvalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and AvalancheA frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look
CosmosEach Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created
PolkadotParachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.
AvalancheAvalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.
ResultsAll three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅
CosmosTendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.
PolkadotPolkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.
AvalancheAvalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.
ResultsAvalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
CosmosTendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.
PolkadotPolkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three
AvalancheAvalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.
ResultsWith regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅
CosmosEvery Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.
PolkadotShared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.
AvalancheA subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional
ResultsShared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.
CosmosThe Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.
PolkadotThe Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.
AvalancheAvalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.
ResultsWhilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.
CosmosCosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.
PolkadotWith polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.
AvalancheAvalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.
ResultsAvalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
CosmosCosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.
PolkadotPolkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.
AvalancheA subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.
ResultsAll 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.
CosmosThe ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.
PolkadotPolkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.
AvalancheAVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.
ResultsAvalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.
All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

Bitcoin không chỉ tạo ra xu hướng, mở ra một làn sóng mà nó còn trở thành tiêu chuẩn thực tế cho tiền ảo, truyền cảm hứng cho sự ra đời và phát triển của các đồng tiền ảo khác trên thế giới. Bài viết hôm nay chúng ta sẽ tìm hiểu về các đồng tiền ảo phổ biến trên thế giới ngoài đồng Bitcoin (BTC).submitted by san_giao_dich_tienao to u/san_giao_dich_tienao [link] [comments]
Tiền ảo là gì?
Trước khi chúng ta xem xét kỹ hơn một số lựa chọn thay thế cho Bitcoin, hãy tìm hiểu ngắn gọn ý nghĩa của các thuật ngữ như tiền ảo và Altcoin. Tiền ảo có dạng mã hóa hoặc “coin”. Trong khi một số loại tiền ảo đã xâm nhập vào thế giới vật chất ví dụ như tiền trên thẻ tín dụng hoặc các dự án khác thì phần lớn những đồng tiền ảo còn lại như Bitcoin vẫn hoàn toàn vô hình. Tiền ảo đề cập đến các mã rất phức tạp cho phép tạo và xử lý các loại tiền này và các giao dịch của chúng trên các hệ thống phi tập trung.
Tiền ảo hầu như luôn được thiết kế để không bị chính phủ thao túng và không chịu sự quản lý của bất kỳ ngân hàng, chính sách tiền và tài khóa nào. Các loại tiền tệ được mô phỏng theo Bitcoin được gọi chung là Altcoin và thường cố gắng để thể hiện mình là phiên bản sửa đổi hoặc cải tiến của Bitcoin. Mặc dù một số loại tiền này dễ khai thác hơn Bitcoin, nhưng vẫn có những đánh đổi, rủi ro lớn hơn do mức độ thanh khoản, chấp nhận và duy trì giá trị thấp hơn. Để tìm hiểu sâu hơn về tiền ảo là gì thì bạn đọc có thể nhấp vào đây.
Các đồng tiền ảo trên thế giới ngoài Bitcoin
Các đồng tiền ảo phổ biến trên thế giớiDưới đây, chúng tôi sẽ thông tin về các đồng tiền ảo quan trọng, phổ biến trên thế giới ngoài Bitcoin. Tuy nhiên, đầu tiên cần lưu ý là không thể có một danh sách toàn diện về tất cả các đồng tiền ảo ngoài Bitcoin được liệt kê dưới đây. Một lý do đơn giản giải thích cho điều này là vì thực tế có hơn 7.000 đồng tiền điện tử đang tồn tại tính đến tháng 11 năm 2020 và nhiều trong số những đó được cộng đồng những người đầu tư ưa chuộng.
Ethereum (ETH) – một trong các đồng tiền ảo theo sau Bitcoin thành công nhấtGiải pháp thay thế Bitcoin đầu tiên trong danh sách là Ethereum – một nền tảng phần mềm phi tập trung cho phép lưu trữ các hợp đồng thông minh và ứng dụng phi tập trung được xây dựng và chạy mà không có bất kỳ thời gian chết, gian lận, kiểm soát hoặc can thiệp nào từ bên thứ ba. Các ứng dụng trên Ethereum được chạy trên mã hóa dành riêng cho nền tảng của nó là Ether.
Ether giống như một phương tiện di chuyển trên nền tảng Ethereum và được hầu hết các nhà nghiên cứu tìm kiếm để phát triển và chạy các ứng dụng bên trong Ethereum, hoặc bây giờ là bởi các nhà đầu tư đang tìm cách mua các loại tiền kỹ thuật số khác bằng cách sử dụng Ether. Ether, ra mắt vào năm 2015, hiện là đồng tiền kỹ thuật số lớn thứ hai theo vốn hóa thị trường sau Bitcoin, mặc dù nó đứng sau tiền điện tử thống trị với một tỷ suất lợi nhuận đáng kể. Kể từ tháng 1 năm 2020, vốn hóa thị trường của Ether chỉ bằng 1/10 so với Bitcoin.
Trong năm 2014, Ethereum đã tung ra một đợt bán trước cho Ether và nhận được phản hồi tích cực; điều này đã giúp mở ra kỷ nguyên phát hành đồng tiền ban đầu (ICO). Theo Ethereum, nó có thể được sử dụng để “mã hóa, phân quyền, bảo mật và giao dịch bất cứ thứ gì.” Sau cuộc tấn công vào DAO vào năm 2016, Ethereum được chia thành Ethereum (ETH) và Ethereum Classic (ETC). Tính đến ngày 2 tháng 11 năm 2020, Ethereum (ETH) có vốn hóa thị trường là $45,442 tỷ đô la và giá trị mỗi đồng được thông báo là $401.25 đô la.
Ripple (XRP)Ripple là một mạng lưới thanh toán toàn cầu theo thời gian thực cung cấp các khoản thanh toán quốc tế tức thì và chi phí thấp. Trình làng vào năm 2012, Ripple cho phép các ngân hàng giải quyết các khoản thanh toán xuyên biên giới trong thời gian thực với ưu điểm là sự minh bạch từ đầu đến cuối và chi phí thấp hơn. Sự đồng thuận của Ripple (phương pháp cấu thành) độc đáo ở chỗ nó không không yêu cầu khai thác.
Thật vậy, tất cả các mã thông báo XRP của Ripple đã được khai thác trước khi ra mắt, có nghĩa là không có sự tạo ra của XRP theo thời gian, chỉ có việc giới thiệu và loại bỏ XRP khỏi nguồn cung thị trường theo hướng dẫn của mạng. Bằng cách này, Ripple tạo ra sự khác biệt so với Bitcoin và nhiều loại Altcoin khác. Vì cấu trúc của Ripple không yêu cầu khai thác, nó làm giảm việc sử dụng sức mạnh tính toán và giảm thiểu độ trễ mạng.
Cho đến nay, Ripple đã rất thành công với mô hình kinh doanh này. Nó vẫn là một trong những loại tiền kỹ thuật số hấp dẫn nhất trong số các tổ chức tài chính truyền thống đang tìm cách đổi mới thanh toán xuyên biên giới. Hiện nó cũng là tiền điện tử lớn thứ ba trên thế giới xét theo vốn hóa thị trường tổng thể. Tính đến ngày 2 tháng 11 năm 2020, Ripple có vốn hóa thị trường là $11,001 tỷ đô la và giá trị mỗi đồng được thông báo là $0.24 đô la.
Litecoin (LTC) – Top 10 các đồng tiền ảo có vốn hóa thị trường cao nhất
Đồng tiền ảo Litcoin (LTC)
Litecoin được ra mắt vào năm 2011, là một trong những đồng tiền điện tử đầu tiên đi theo chân của Bitcoin và thường được gọi ví von là “silver to bitcoin’s gold”. Nó được tạo ra bởi một cựu kỹ sử của Google, Charlie Lee, một sinh viên tốt nghiệp MIT. Litecoin hoạt động dựa trên mạng thanh toán toàn cầu có mã nguồn mở mà không bị kiểm soát bởi bất kỳ cơ quan trung ương nào và sử dụng thuật toán”scrypt” làm bằng chứng công việc, có thể được giải mã với sự trợ giúp của CPU cung cấp cho người tiêu dùng.
Mặc dù Litecoin có nhiều mặt giống Bitcoin nhưng nó có tốc độ tạo khối nhanh hơn vì vậy cung cấp thời gian xác nhận giao dịch cũng nhanh hơn. Ngoài các nhà phát triển, ngày càng có nhiều người bán chấp nhận Litecoin. Đến ngày 2 tháng 11 năm 2020, vốn hóa thị trường của Litecoin là $3,694 tỷ đô la và giá trị mỗi đồng thông báo là $56.16 đô la, khiến nó trở thành đồng tiền ảo lớn thứ sáu trên thế giới.
Tether (USDT)Tether là một trong những đồng tiền đầu tiên và phổ biến nhất của một nhóm được gọi là Stablecoin, tiền điện tử nhằm cố định giá trị thị trường của chúng với một loại tiền tệ hoặc điểm tham chiếu bên ngoài khác để giảm sự biến động. Bởi vì hầu hết các loại tiền kỹ thuật số ngay cả những loại tiền lớn như Bitcoin, đã trải qua những giai đoạn biến động mạnh thường xuyên. Tether và các loại tiền ổn định khác cố gắng làm dịu biến động giá để thu hút những người dùng có thể thận trọng.
Tether được ra mắt vào năm 2014 tự mô tả mình là “một nền tảng hỗ trợ blockchain được thiết kế để tạo điều kiện thuận lợi cho việc sử dụng các loại tiền tệ định danh theo cách thức kỹ thuật số để giảm thiểu sự biến động và phức tạp thường liên quan đến tiền tệ kỹ thuật số. Vào ngày 2 tháng 11 năm 2020, Tether là tiền điện tử lớn thứ ba theo vốn hóa thị trường, với tổng vốn hóa thị trường là $16,680 tỷ đô la và giá trị mỗi đồng là $1,00 đô la.
Bitcoin Cash (BCH) – đứng thứ 5 về vốn hóa thị trường trong các đồng tiền ảoBitcoin Cash (BCH) giữ một vị trí quan trọng trong lịch sử của Altcoin vì nó là một trong những đồng có hard fork sớm nhất và thành công nhất từ Bitcoin gốc. Trong thế giới tiền ảo, fork diễn ra là kết quả của các cuộc tranh luận giữa các nhà phát triển và thợ đào coin. Do tính chất phi tập trung của tiền tệ kỹ thuật số, các thay đổi bán buôn đối với mã cơ bản của mã thông báo hoặc đồng xu trong tầm tay phải được thực hiện do sự đồng thuận chung. Quá trình này có cơ chế thay đổi tùy theo loại tiền điện tử cụ thể.
Khi các phe phái khác nhau không thể đi đến thỏa thuận, đôi khi tiền kỹ thuật số bị chia tách, với bản gốc vẫn đúng với mã gốc của nó và bản sao khác bắt đầu hoạt động như một phiên bản mới của đồng tiền trước đó, hoàn chỉnh với các thay đổi đối với mã của nó. BCH bắt đầu hoạt động vào tháng 8 năm 2017 do một trong những đợt chia tách này. Cuộc tranh luận đã dẫn đến việc tạo ra BCH có liên quan đến vấn đề khả năng mở rộng đó là mạng Bitcoin có giới hạn nghiêm ngặt về kích thước khối một megabyte (MB). BCH tăng kích thước khối từ một MB lên 8MB, với ý tưởng là các khối lớn hơn sẽ cho phép thời gian giao dịch nhanh hơn. Nó cũng thực hiện các thay đổi khác, bao gồm việc loại bỏ giao thức Segregated Witness ảnh hưởng đến không gian khối. Kể từ ngày 2 tháng 11 năm 2020, BCH có vốn hóa thị trường là $4,983 tỷ đô la và giá trị mỗi đồng là $268.51 đô la.
Monero (XMR)Monero là một loại tiền tệ an toàn, riêng tư và không thể bị theo dõi. Đồng tiền ảo mã nguồn mở này đã được ra mắt vào tháng 4 năm 2014 và nhanh chóng thu hút sự quan tâm đông đảo của cộng đồng những người đam mê đồng tiền mã hóa. Sự phát triển của loại tiền điện tử này hoàn toàn dựa trên sự đóng góp và hướng tới cộng đồng. Monero đã được ra mắt với trọng tâm mạnh mẽ là phân cấp và khả năng mở rộng, đồng thời nó cho phép hoàn toàn quyền riêng tư bằng cách sử dụng một kỹ thuật đặc biệt gọi là “ring signatures”.
Với kỹ thuật này, sẽ có một nhóm các chữ ký mật mã bao gồm ít nhất một người tham gia thực sự và tất cả chúng đều có vẻ hợp lệ vì chữ ký thực không thể bị cô lập. Với cơ chế bảo mật đặc biệt như vậy, Monero đã phát triển một thứ có tiếng tăm không kém, nó có liên quan đến các hoạt động tội phạm trên khắp thế giới. Tuy nhiên, cho dù nó được sử dụng cho mục đích tốt hay xấu, không thể phủ nhận rằng Monero đã giới thiệu những tiến bộ công nghệ quan trọng cho tiền điện tử. Tính đến ngày 2 tháng 11 năm 2020 Monero có vốn hóa thị trường là $2,246 tỷ đô la và giá trị mỗi mã thông báo là $126.57 đô la.
Đồng tiền ảo EOS
Ngoài Libra, một trong những đồng tiền kỹ thuật số mới nhất lọt vào danh sách này là EOS. Được công bố vào tháng 6 năm 2018, EOS được tạo ra bởi Dan Larimer – nhà tiên phong tiền điện tử. Trước khi làm việc cho EOS, Larimer đã là nhà sáng lập sàn tiền ảo Bitshares cũng như nền tảng truyền thông xã hội dựa trên blockchain Steemit. Giống như lịch sử của các loại tiền điện tử khác trong danh sách này, EOS được thiết kế sau Ethereum, vì vậy nó cung cấp một nền tảng mà các nhà phát triển có thể xây dựng các ứng dụng phi tập trung. Tuy nhiên, EOS có nhiều điều đáng chú ý vì nhiều lý do.
Đầu tiên, đợt chào bán đồng tiền ban đầu của nó là một trong những đợt phát hành lâu nhất và có lợi nhuận cao nhất trong lịch sử, thu về mức kỷ lục 4 tỷ đô la Mỹ trong quỹ nhà đầu tư thông qua các nỗ lực tìm nguồn cung ứng cộng đồng kéo dài một năm. EOS cung cấp một cơ chế bằng chứng cổ phần được ủy quyền mà nó hy vọng có thể cung cấp khả năng mở rộng vượt xa các đối thủ cạnh tranh.
EOS bao gồm EOS.IO, tương tự như hệ điều hành của máy tính và hoạt động như mạng blockchain cho tiền kỹ thuật số, cũng như tiền EOS. EOS cũng mang tính cách mạng vì không có cơ chế khai thác để sản xuất đồng tiền. Thay vào đó, các nhà sản xuất khối tạo ra các khối và được thưởng bằng mã thông báo EOS dựa trên tỷ lệ sản xuất của họ. EOS bao gồm một hệ thống các quy tắc phức tạp để điều chỉnh quá trình này. Với ý tưởng sẽ dân chủ và phi tập trung hơn so với các loại tiền điện tử khác trên thế giới. Kể từ ngày 2 tháng 11 năm 2020, EOS có vốn hóa thị trường là $2,361 tỷ đô la và giá trị mỗi mã thông báo là $2.52 đô la.
Bitcoin SV (BSV)Bitcoin SV (BSV), với “SV” trong trường hợp này là viết tắt của “Satoshi Vision”, là một hard fork của Bitcoin Cash. Theo nghĩa này, BSV là một nhánh rẽ của mạng Bitcoin ban đầu. Việc nâng cấp mạng theo kế hoạch cho tháng 11 năm 2018 đã dẫn đến một cuộc tranh luận kéo dài giữa các phe phái khai thác và phát triển trong cộng đồng BCH, dẫn đến hard fork và sự ra đời của BSV. Các nhà phát triển Bitcoin SV đề nghị rằng tiền điện tử này nên khôi phục giao thức ban đầu của nhà phát triển Bitcoin- Satoshi Nakamoto và đồng thời cho phép các phát triển mới để tăng tính ổn định, cho phép khả năng mở rộng. Các nhà phát triển Bitcoin SV cũng ưu tiên bảo mật và thời gian xử lý giao dịch nhanh chóng. 2 tháng 11 năm 2020, BSV có vốn hóa thị trường là $3,074 tỷ đô la và giá trị mỗi mã thông báo là $165.64 đô la.
Binance Coin (BNB)Binance Coin (BNB) là đồng tiền ảo chính thức của nền tảng trao đổi tiền điện tử Binance. Thành lập vào năm 2017, Binance đã nhanh chóng vươn lên trở thành sàn giao dịch lớn nhất trên toàn cầu về khối lượng giao dịch tổng thể. Bên cạnh đó Binance Coin cho phép người dùng Binance giao dịch hàng chục loại tiền điện tử khác nhau một cách hiệu quả trên nền tảng Binance. Ngoài ra, BNB được sử dụng để hỗ trợ phí giao dịch trên sàn giao dịch và cũng có thể được sử dụng để thanh toán cho một số hàng hóa và dịch vụ, bao gồm phí đi lại và các dịch vụ khác. Kể từ ngày 2 tháng 11 năm 2020, BNB có vốn hóa thị trường là $4,145 tỷ đô la và giá trị mỗi mã thông báo là $28.71 đô la.

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.

There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
