## ما هي IOST (IOST)؟

تصف IOST نفسها بأنه [شبكة](https://coinmarketcap.com/alexandria/glossary/network) "فائقة السرعة" وكاملة و[غير مركزية](https://coinmarketcap.com/alexandria/glossary/decentralized) تستند إلى [سلسلة الكتل](https://coinmarketcap.com/alexandria/glossary/blockchain)، ونظام بيئي مع عقد و[محافظ](https://coinmarketcap.com/alexandria/glossary/wallets) خاصة به، مُستند إلى [بروتوكول](https://coinmarketcap.com/alexandria/glossary/protocol) [إجماع](https://coinmarketcap.com/alexandria/glossary/consensus) "الجيل التالي" المسمى "إثبات المصداقية".

### من هم مُؤسسو IOST؟

تم إطلاق المشروع في يناير 2018 بواسطة جيمي تشونغ و تيرينس وانغ وجاستن لي و راي شياو و سا وانغ و كيفن تان.

أسس تشونغ شركات تقنية ناشئة أخرى في الولايات المتحدة والصين. وخلال أيام دراسته الجامعية، باع تشونغ شركته الأولى مقابل 40 مليون دولار — وكانت عبارة عن سوق حيث يمكن للطلاب تبادل الملاحظات الصفية. وعاد بعد ذلك إلى بكين وشارك في تأسيس IOST، من بين مشاريع أخرى.

تشمل خبرة وانغ السابقة العمل كمهندس برمجيات في أوبر. وإنّ وانغ حاصل على درجة علمية في علوم الكمبيوتر من جامعة مينيسوتا وماجستير في علوم الكمبيوتر من جامعة برينستون.

بينما عمل لي سابقًا كمساعد مصرفي استثماري في Goldman Sachs وعالم بيانات في Mobike. وتخرج بدرجة في الرياضيات التطبيقية وعلوم الكمبيوتر. في حين كان تان مؤسسًا مشاركًا في Ethercap، بينما حصل على درجة علمية في علوم الكمبيوتر من جامعة Tsinghua.

شارك شياو في تأسيس Dora — جنبًا إلى جنب مع جيمي و سا — وهي شركة ذكاء اصطناعي (AI) تُركز على الأكشاك الذكية. درس علوم الكمبيوتر والاقتصاد الكمي في الجامعة.

### ما الذي يُميز IOST؟

تعد البنية التحتية لسلسة الكتل الخاصة بـ IOST مفتوحة المصدر ومصممة لتكون آمنة وقابلة للتطوير — كل ذلك على أمل أن تكون بمثابة العمود الفقري للخدمات عبر الإنترنت في المستقبل.

طور الفريق [خوارزمية](https://coinmarketcap.com/alexandria/glossary/algorithm) [إجماع](https://coinmarketcap.com/alexandria/glossary/consensus) "إثبات المصداقية" لضمان [المعاملات](https://coinmarketcap.com/alexandria/glossary/transaction-tx) على الشبكة آمنة وفعالة.

إنّ أحد أكبر التحديات التي تهدف IOST إلى حلها يركز على كيف أن الشركات الكبرى قد لا تكون قادرة على تبني تقنية سلسلة الكتل في بيئة تواجه العملاء ما لم تكن قابلة للتطوير. تم طرح رمز إنترنت الخدمات كطريقة لمعالجة هذه المشكلة.

لفهم IOST، فإن أفضل طريقة للقيام بذلك هي مقارنتها بأقرب منافسيها: [Ethereum](https://coinmarketcap.com/ar/currencies/ethereum)، وهي منصة العقود الذكية الأكثر شيوعًا للمطورين. يمكن أيضًا مقارنتها بـ [EOS](https://coinmarketcap.com/ar/currencies/eos) و [TRON](https://coinmarketcap.com/ar/currencies/tron)، وهما منصات تعاقدية ذكية قابلة للتطوير بدرجة كبيرة مع استخدام عالٍ.

يتمثل الاختلاف الأكبر بين IOST ومنافسيها في الطريقة التي تدعي أنها تستطيع معالجة ما يصل إلى 100,000 معاملة في الثانية مقارنةً بـ 20 معاملة في الثانية لـ Ethereum و 2,000 معاملة في الثانية لـ Tron و4,000 معاملة في الثانية لـ EOS .

من أجل الوصول إلى سرعات المعاملات هذه، أنشأ فريق IOST بنية سلسلة كتل جديدة، والتي تقدم وتجمع بين العديد من الابتكارات بما في ذلك بروتوكول Distributed Randomness والتجزئة الموزعة الفعالة (Efficient Distributed Sharding) و TransEpoch و Atomix و إثبات المصداقية و Micro State Blocks.

### كم عدد عملات IOST (IOST) المُتداولة؟

لدى IOST إجمالي عرض يبلغ 21 مليار رمز. تم عقد العرض الأولي للعملة (ICO) في يناير 2018 حيث تم بيع 40%، مما أدى إلى جمع حوالي 31.3 مليون دولار من ETH في ذلك الوقت.

أما فيما يخص المتبقي، فقد احتفظت مؤسسة IOST بنسبة 35%، وخصصت 12.5% لبناء المجتمع، و 10% إلى فريق IOST و 2.5% مخصصة للمستثمرين والمستشارين.

### كيف يتم تأمين شبكة IOST؟

من أجل التنافس مع المئات من سلاسل الكتل المتخصصة، تعتمد IOST بشكل كبير على بروتوكول إثبات المصداقية (PoB) والتجزئة الموزعة الفعالة (EDS) لتحسين قابلية التوسع والأمان في سلسلة الكتل.

تم تصميم IOST لاستخدام المؤسسات، لذلك تدعي أنها قادرة على التعامل مع الأحمال الثقيلة التي تنتجها شركات التكنولوجيا الكبرى مثل Amazon و Google و Facebook. ويبدو أن الشراكات مفتاح نجاح المشروع.

### أين يُمكنك شراء IOST (IOST)؟

يمكن شراء IOST من العديد من منصات التداول مثل Bittrex و CoinEx و Livecoin و Binance و Bitrue.

IOST成立于2017年，得到红杉资本、经纬、甄选等全球一线美元投资机构的支持。

IOST是为在线服务商开发的企业级区块链应用平台。

NEM is a blockchain platform that was launched in March of 2015. It was one of the pioneers of the cryptocurrency industry, and sought to improve on the imperfections found on other chains at the time. It was one of the first non-turing complete chains to feature user-defined tokens (called mosaics), namespaces, multisignature accounts, and a P2P reputation system based on EigenTrust++. Its most notable contribution to the space is the proof-of-importance consensus mechanism, which sought to reward on-chain activity and deter the concentration of wealth commonly associated with proof-of-stake. Its client, NIS, is written in Java.

NEM has a global community. It sees the most utility as an alternative form of payment for businesses and vendors, and has a variety of social media apps built on top of it in Japan, such as nemgraph, a community-driven owned and operated alternative to Instagram.

In December 2021, NEM was hard forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled Harlock, this hard fork signaled the community’s intent to take NEM from a shadow of its former self into the world’s leading payments platform for on-chain and off-chain media content.

DigiByte (DGB) is an open source blockchain and asset creation platform. Development began in October 2013 and the genesis block of its DGB token was mined in January 2014 as a fork of Bitcoin (BTC).

A longstanding public blockchain and cryptocurrency, DigiByte uses five different algorithms to improve security, and originally aimed to improve on the Bitcoin blockchain’s security, capacity and transaction speed.

DigiByte consists of three layers: a smart contract “App Store,” a public ledger and the core protocol featuring nodes communicating to relay transactions.

DigiByte

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.

Ontology

Holo is a peer-to-peer distributed platform for hosting decentralized applications built using Holochain, a framework for developing DApps that does not require the use of blockchain technology. The goal of Holo is to serve as a bridge between the broader internet and apps built using Holochain, offering an ecosystem and marketplace in which DApps are easily accessible, as they are hosted on the internet by Holo network participants.

The Holo network will be facilitated using a token called HoloFuel, which is actively being tested and will act as an accounting system to pay hosts for their services. In 2018, the project minted an ERC-20 token, HOT — also known as HoloToken — as an "IOU" that will be redeemable for HoloFuel upon launch.

Holo is still in development and is expected to launch for open alpha and beta testing by 2021.

Holo

Qtum (pronounced ‘“quantum”)  is a proof-of-stake (PoS) smart contract open-source blockchain platform and value transfer protocol. It aims to bring together the strengths of Bitcoinand Ethereumin one chain. Qtum is built on Bitcoin's UTXO transaction model, with the added functionality of smart contract execution and DApps. Recently, the platform added support for DeFi applications. As of March 2021, there are more than 20 tokens created on the Qtum blockchain.

To learn more about this project, check out our deep dive of Qtum.

The project was announced in March 2016 and held an ICO a year after, in March 2017, which brought its founders $15 million USD. The Qtum main chain was released on Sept.13, 2017. Initially, the Qtum coin was issued as a ETH-20 token, but with the launch of the mainnet, it was converted to native blockchain.

Qtum

Zilliqa is a public, permissionless blockchain that is designed to offer high throughput with the ability to complete thousands of transactions per second. It seeks to solve the issue of blockchain scalability and speed by employing sharding as a second-layer scaling solution. The platform is home to many decentralized applications, and as of October 2020, it also allows for staking and yield farming.

Development work officially started on Zilliqa in June 2017, and its testnet went live in March 2018. A little over a year later, in June 2019, the platform launched its mainnet.

The native utility token of Zilliqa, ZIL, is used to process transactions on the network and execute smart contracts.

Starting as an open-source project in 2017, IoTeX has built a decentralized platform whose aim is to empower the open economics for machines — an open ecosystem where people and machines can interact with guaranteed trust, free will, and under properly designed economic incentives.

With a global team of over 40 research scientists and engineers, IoTeX has built their EVM-compatible blockchain from scratch using the innovative Roll-DPoS consensus and launched in 2019 April, which has been running by 100+ delegates worldwide and has processed more than 10 million transactions already. On top of the IoTeX blockchain, the team has built the essential blocks of infrastructures to connect with Ethereum, BSC, and Heco blockchains such as ioPay wallet (https://iopay.me/) and ioTube bridge (https://iotube.org/), which serve ten thousands of users. IoTeX helps EVM-based DApps scale without concerning expensive gas fees!

Besides, middleware such as Decentralized Identity, Confidential Computing, and Secure Hardware has been built on top of the IoTeX blockchain. This has enabled the creation of self-sovereign devices such as Ucam, and real-world data oracles like Pebble. Ucam (https://ucam.iotex.io/) has been deployed to over 3000 households (http://iott.network/). Meanwhile, Pebble has been launched to more than 300 developers initially, and enables innovative Dapps to connect the physical world with the crypto world, such as real-world NFTs, weather derivatives and machine learning-as-mining.

IoTeX

JUST is a popular new decentralized finance (DeFi) ecosystem built for the TRON blockchain. It is an entire suite of products that are mostly centered around a decentralized stablecoin lending platform known as JustStable.

The platform launched in August 2020 following an initial exchange offering (IEO) on the Poloniex LaunchBase platform earlier that same year, but the native governance token of the platform (JST) has been circulating since May 2020.

It is a two-token ecosystem built around the USDJ and JUST (JST) tokens. USDJ is a multi-collateral stablecoin that has its value pegged to the value of the US dollar (USD), whereas JST has a variety of functions on the platform — paying interest, helping maintain the platform and participating in its governance, helping to set parameters like interest rates (stability fees) and the minimum collateralization ratio.

To obtain USDJ on JUST, traders need to deposit collateral in the form of supported collateral tokens — including TRON (TRX), which are exchanged to PTRX tokens and locked as collateral forming a collateralized debt position (CDP). Depending on the amount of collateral deposited, users can then mint and withdraw USDJ, which must later be repaid to retrieve the initial collateral.

The platform is designed to provide a fair and borderless hub of DeFi products, that any TRON user can access.

JUST

Basic Attention Token, or BAT, is the token that powers a new blockchain-based digital advertising platform designed to fairly reward users for their attention, while providing advertisers with a better return on their ad spend.

To learn more about this project, check out our deep dive of Basic Attention Token.

This experience is delivered through the Brave Browser, where users can watch privacy-preserving adverts and receive BAT rewards for doing so. On the other hand, advertisers can deliver targeted ads to maximize engagement and cut down losses due to ad fraud and abuse.

The Basic Attention Token itself is the unit of reward in this advertising ecosystem, and is exchanged between advertisers, publishers and users. Advertisers pay for their advertising campaigns in BAT tokens. Out of this budget, a small portion is distributed to advertisers, while 70% is distributed to users — whereas the intermediaries that typically drive up advertising costs are cut out of the equation to improve cost-efficiency.

Basic Attention Token launched in 2017 following one of the fastest sell-out initial coin offerings (ICOs) of all time, with the platform raising a total of $35 million in under a minute. Since then, it has rolled out its attention-based advertising experience to users in most countries through its Brave Rewards program.

As of November 2020, the United States, the United Kingdom and Canada had the most active advertising campaigns.

Basic Attention Token

Ravencoin is a digital peer-to-peer (P2P) network that aims to implement a use case specific blockchain, designed to efficiently handle one specific function: the transfer of assets from one party to another. Built on a fork of the Bitcoin code, Ravencoin was announced on Oct. 31, 2017 and released binaries for mining on Jan. 3, 2018 with what is called a fair launch: no premine, ICO or masternodes. It was named in reference to a TV show Game of Thrones.

OMG Network, formerly known as OmiseGo, is a non-custodial, layer-2 scaling solution built for the Ethereum blockchain. As an Ethereum scaling solution, OMG Network is designed to allow users to transfer ETH and ERC20 tokens significantly faster and cheaper than when transacting directly on the Ethereum network.

The network is based on a novel scaling solution called MoreViable Plasma, which uses a sidechain architecture to group several transactions off-chain into a batch, which can then be verified as a single transaction on the Ethereum root chain. According to OMG Network, this technology has the potential to scale Ethereum to thousands of transactions per second (TPS) — instead of the 10 to 14 tps Ethereum 1.0 is currently capable of.

The network is powered by the OMG utility token, which can be used as one of the payment methods for fees on the OMG Network, and will eventually be stakable — helping to secure the network in return for rewards.

OMG Network

Verge is a privacy-focused cryptocurrency and blockchain that seeks to offer a fast, efficient, decentralized payments network that improves upon the original Bitcoin (BTC) blockchain. It includes additional privacy features including integrating the anonymity network Tor into its wallet, called vergePay, and providing the option of sending transactions to stealth addresses.

The project describes itself as community-driven, relying on volunteers and priding itself on being open source.

Verge was first launched in October 2014 as DogeCoinDark, a fork of Peercoin (PPC). In February 2016, it was renamed Verge in order to rebrand for easier mass-market adoption and to distinguish itself from Dogecoin (DOGE), with which it has no direct connection. The project is now based on the Bitcoin source code.
