## ما هي ايوتكس (IOTX)؟

بدأت كمشروع مفتوح المصدر في عام 2017، ثم قامت "ايوتكس" ببناء منصة لامركزية تهدف إلى تمكين الاقتصاد المفتوح للآلات — حيث تعمل كنظام بيئي يتيح للناس والآلات التفاعل بثقة مضمونة وإرادة حرة مع وجود نظام حوافز مصمم بشكل مناسب.

استفادت "ايوتكس" من فريق عالمي يضم أكثر من 40 عالم أبحاث ومهندس لتقوم ببناء سلسلة كتل متوافقة "آلة إيثريوم الافتراضية" من الصفر باستخدام آلية إجماع (Roll-DPoS) المبتكرة وتم إطلاقها في أبريل 2019، حيث تم تشغيلها بواسطة أكثر من 100 عقدة من مختلف أنحاء العالم التي تستطيع معالجة أكثر من 10 مليون معاملة. وبالإضافة إلى سلسلة كتل "ايوتكس"، قام الفريق ببناء أساسات البنية التحتية للتواصل مع سلاسل كتل إيثريوم، وبينانس سمارت تشين، وهيكوتشين مثل محفظة "ايوباي" ([https://iopay-wallet.iotex.io/](https://iopay-wallet.iotex.io/)) وجسر ايوتيوب (https://tube.iotex.io/)، التي تخدم عشرات آلاف المستخدمين. تساعد "ايوتكس" (IoTeX) على توسيع نطاق التطبيقات اللامركزية القائمة على آلة إيثريوم الافتراضية دون القلق بشأن رسوم الغاز باهظة الثمن!

إلى جانب ذلك، تم بناء برامج وسيطة مثل الهوية اللامركزية (Decentralized Identity)، والحوسبة السرية (Confidential Computing)، والأجهزة الآمنة (Secure Hardware) على سلسلة كتل ايوتكس وقد مكّن ذلك من تفعيل أجهزة مستقلة مثل أوراكل (Ucam) وبيانات العالم الحقيقية مثل (Pebble). سابقاً (https://ucam.iotex.io/) تم نشره في أكثر من 3000 منزل؛ حالياً (http://iott.network/) ولا يزال ينمو. وفي الوقت نفسه، تم إطلاق (Pebble) لأكثر 300 مطور في البداية حيث يتيح للتطبيقات اللامركزية التي تربط العالم المادي بعالم التشفير، مثل الرموز غير القابلة للاستبدال في العالم الحقيقي، ومشتقات الطقس، والتعلم الآلي كالتعدين.

### من هم مؤسسو ايوتكس؟

مؤسسو "ايوتكس" هم راولين تشاي، وكيفان جو، وشينكسين فان، وجينغ صن.

بالإضافة إلى كونه المؤسس المشارك في "ايوتكس"، يشغل راولين تشاي أيضاً منصب مستشار في (BootUP Ventures)، وهو كذلك عضو في مجموعة (Industrial Distributed Ledger Task Group) في (Industrial Internet Consortium). كما عمل سابقاً كقائد البحث والتطوير في مشاريع العملات المشفرة والأمن الهندسي في "أوبر".

كيفان جو هو أيضاً أحد مؤسسي (Hyperconnect Lab). وعمل سابقاً كباحث ومديراً هندسياً في فيسبوك.

أما شينكسين فان فقد عمل قبل المشاركة في تأسيس "ايوتكس" كمهندس أبحاث أول في مركز بوش للأبحاث والتكنولوجيا، أمريكا الشمالية. كما عمل كمساعد باحث ومدير مشروع في جامعة واترلو.

من جهتها، عملت جينغ صن كشريك إداري في (Sparkland Capital). وهي مستثمرة في مجمّعات السيولة في (Polychain Capital) ومستثمرة ملاك في (Rippling).

### ما الذي يميّز ايوتكس؟

تمثّل "ايوتكس" العمود الفقري اللامركزي لاقتصاديات الآلات التي تتدرّج من الأجهزة المنزلية الذكية إلى المركبات المستقلة. ولتحقيق هذه الغاية، قامت "ايوتكس" ببناء وإطلاق سلسلة كتل سريعة وعالية الأداء ومتوافقة مع "آلة إيثريوم الافتراضية" بحيث توفر المرونة وقابلية التوسع لمختلف التطبيقات. إلى جانب ذلك، يتم بناء التطبيقات الوسيطة واللامركزية على سلسلة الكتل لتمكين الأجهزة الذاتية وأوراكل العالم الحقيقي.

ايتوكس (IOTX) هي العملة التي تشغل بروتوكول سلسلة الكتل الأساسي عبر استخدامها لدفع رسوم الغاز. بينما تخضع لآلية (Burndrop) (http://burndrop.iotex.io/) وهو عبارة عن تصميم اقتصادي فريد ينتج عنه انكماش إعداد عملات (IOTX) كلما زاد عدد الأجهزة التي يتم التنسيق بينها عبر "ايوتكس".

LRC is the Ethereum-based cryptocurrency token of Loopring, an open protocol designed for the building of decentralized crypto exchanges.

In 2020, the average daily trading volume of the entire cryptocurrency market fluctuated in the approximate range of $50-$200 million. Most of that trading is conducted on centralized cryptocurrency exchanges — online platforms operated by private companies that store users’ funds and facilitate the matching of buy and sell orders.

Such platforms have a number of downsides common to all of them, so a new type of exchange — decentralized— has emerged to try to alleviate these disadvantages. However, fully decentralized exchanges are not without their own flaws.

Loopring’s purported goal is to combine centralized order matching with decentralized on-blockchain order settlement into a hybridized product that will take the best aspects of both centralized and decentralized exchanges.

LRC tokens became available to the public during an initial coin offering (ICO) in August 2017, while the Loopring protocol was first deployed on Ethereum mainnet in December 2019.

Loopring

Enjin Coin is a project of Enjin, a company that provides an ecosystem of interconnected, blockchain-based gaming products. Enjin's flagship offering is the Enjin Network, a social gaming platform through which users can create websites and clans, chat, and host virtual item stores.

Enjin allows game developers to tokenize in-game items on the Ethereum blockchain. It uses Enjin Coin, an ERC-20 token, to back the digital assets issued using its platform, meaning that items can be bought, sold and traded with real-world value.

Enjin Coin was first announced in July 2017, and it launched on the Ethereum mainnet in June 2018.

Enjin Coin (ENJ) is a digital store of value used to back the value of blockchain assets like non-fungible tokens (NFTs).
Every asset minted with the Enjin Platform contains ENJ, a minting resource which is locked inside NFTs and removed from circulation. Minting blockchain assets with ENJ provides a variety of benefits to creators and users:

Infuses them with a reserve value

Ensures their transparency and scarcity

Gives them instant liquidity

Provides utility in games and apps

Anti-inflationary

Enjin's "melting" functionality allows users to destroy their blockchain assets at any time to retrieve the ENJ value from within.

The Enjin blockchain ecosystem aims to offer software products that make it easy for everyone to develop, trade, monetize, and market with blockchain.

Founded in 2009, Enjin has roots in the gaming industry, with the company’s first product, a gaming community platform called the Enjin Network, growing to 20 million users over the course of a decade.

In 2017 following an ICO, Enjin established itself as a leading blockchain ecosystem developer, building a suite of software products that enable anyone to easily mint, manage, trade, distribute, and integrate blockchain assets.

Enjin’s co-founder Witek Radomski wrote the code for one of the first ever non-fungible tokens (NFTs) and is also the co-author of the ERC-1155 Ethereum token standard.

Built on top of an on-chain infrastructure, the Enjin ecosystem enables game developers and businesses of all sizes to use tokenized digital assets as part of their acquisition, retention, engagement, and monetization strategies. The Enjin ecosystem is fueled by Enjin Coin (ENJ), a cryptocurrency used to back the value of blockchain assets.

Fantom is a directed acyclic graph (DAG) smart contract platform providing decentralized finance (DeFi) services to developers using its own bespoke consensus algorithm.

Together with its in-house token FTM, Fantom aims to solve problems associated with smart-contract platforms, specifically transaction speed, which developers say they have reduced to under two seconds.

The Fantom Foundation, which oversees the Fantom product offering, was originally created in 2018, with the launch of OPERA, Fantom’s mainnet, coming in December 2019.

Fantom is an open-source decentralized smart contract platform for DApps and digital assets that was created as an alternative to Ethereum. Fantom has the goal of overcoming the limitations of previous generation blockchains and balancing three components: scalability, security and decentralization. The project offers a set of tools to simplify the process of integrating existing DApps, as well as a detailed staking reward system and built-in DeFi instruments.

Fantom is a Layer-1 blockchain that uses a scratch-built consensus mechanism and independent consensus layer, Lachesis, to facilitate DeFi and related services on the basis of smart contracts. Lachesis provides security for other layers as well, including Opera, Fantom's EVM-compatible smart contract chain. The long-playing mission of the project is to “grant compatibility between all transaction bodies around the world.”

One of Fantom's key strengths is its performance and efficient transaction processing, namely thousands of transactions per second, where transactions are settled in 1-2 seconds, and the cost is fractions of a cent per transaction. As a result, Fantom provides higher scalability but at a lower cost.

The ecosystem is based on two main technologies: Lachesis protocol and Opera.

The Lachesis protocol is the core consensus layer that secures the Fantom network by providing both transaction speed and security.

Lachesis is an aBFT consensus engine that uses a directed acyclic graph (DAG) algorithm. How it works: network data can be processed at different times, and the network filters the participants, allowing only one third, which are allocated due to erroneous or malicious behavior, without compromising network processes.

Fantom's Asynchronous Byzantine Fault Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism maintains the efficiency of the entire network, its design provides security at maximum speed. Fantom developers emphasize that the PoS mechanism is a leaderless phenomenon — there are no leaders of blocks and participants, and anyone can join (or leave) the network of nodes at a convenient moment.

The key qualities of Lachesis are: asynchronous, leaderless, Byzantine fault-tolerant, and near-instant finality.

As for Opera, it's an application development layer or Fantom's mainnet deployment platform, permissionless and open-source hosting DApps. Thanks to EVM integration and support for the Solidity programming language, Fantom has a full set of smart contract capabilities, which allows users to seamlessly interact with Ethereum platforms while maintaining the advantage of Fantom's transaction efficiency.

The Fantom Foundation concluded that removing block leaders improves network security, so Opera uses a PoS model and leaderless validators (validators do not determine which blocks are valid).

In addition to being a fast, secure and cheap payment platform that enables to make fast and secure payments at minimal cost, Fantom also features on-chain governance where users vote with FTM tokens (one token equals one vote). Of the features: users have the right to express the degree of agreement / disagreement on a scale from 0 to 4.

FTM is the native utility in-house PoS token of Fantom that powers the ecosystem and is applied for payments, network fees, staking, and governance. FTM forms the backbone of transactions, and allows fee collection and staking activities, along with the user rewards the latter represents.

Fantom

The 1inch Network unites decentralized protocols whose synergy enables the most lucrative, fastest, and protected operations in the DeFi space.

The 1inch Network's first protocol is a decentralized exchange (DEX) aggregator solution that searches deals across multiple liquidity sources, offering users better rates than any individual exchange. The 1inch Aggregation Protocol incorporates the Pathfinder algorithm for finding the best paths across over 400+ liquidity sources on 12 chains: Ethereum, BNB Chain, Polygon, Avalanche, Optimism, Arbitrum, Fantom, Gnosis Chain, Klaytn, Aurora, zkSync and Base.

In just over two years the 1inch DEX aggregator has reached 1M users and surpassed $150B in overall volume on the Ethereum network alone.

The 1inch Limit Order Protocol facilitates the most innovative and flexible limit order swap opportunities in DeFi. The protocol’s features, such as dynamic pricing, conditional orders, and extra RFQ support, power various implementations, including stop-loss and trailing stop orders, as well as auctions.

The 1inch Wallet is a multichain mobile platform that provides an easy-to-navigate interface with secure storing, transaction, and staking capabilities. This versatile wallet was built from the ground up to streamline interacting with 1inch’s features.

The 1INCH token is the governance and utility token of the 1inch Network. 1INCH holders can stake their tokens to participate in the 1inch Network's DAO governance, including the 1inch DAO Treasury management. Also, holders can choose resolvers and earn a part of their fees.

With the 1inch Fusion, users can stake 1INCH tokens to receive Unicorn Power (UP), then subsequently delegate their UP to any 1inch Fusion Resolver to start receiving rewards from them. When staking, there is the option to set a custom or preset lock period. User’s st1INCH tokens cannot be unstaked/withdrawn without penalty until the designated lock period expires.

In December 2020, 1inch raised $12 million in Series A funding, led by Pantera Capital, with others including ParaFi Capital, Blockchain Capital, Nima Capital, and Spartan Group. The funding round was conducted through a SAFT (simple agreement for future tokens) sale.

In December 2021, 1inch has closed a $175 million Series B round, led by Amber Group. Among about 50 investors that participated in the funding event are Jane Street, VanEck, Fenbushi Capital, Alameda Research, Celsius, Nexo, Tribe Capital and Gemini Frontier Fund.

Artists can upload music, stored and distributed by content and discovery nodes, that fans can listen to for free. Currently, Audius rewards content creators through rewards like featuring in the weekly trending lists. In the future, it plans to integrate stablecoins for artists to offer paid content, as well as artist tokens that give fans the ability to access exclusive content, potentially cooperating with platforms like Rally.

Audius

Decentraland (MANA) defines itself as a virtual reality platform powered by the Ethereum blockchain that allows users to create, experience, and monetize content and applications.

In this virtual world, users purchase plots of land that they can later navigate, build upon and monetize.

Decentraland was launched following a $24 million initial coin offering (ICO) that was conducted in 2017. The virtual world launched its closed beta in 2019 and opened to the public in February 2020. Since then, users have created a wide range of experiences on their parcels of LAND, including interactive games, sprawling 3D scenes and a variety of other interactive experiences.

Decentraland uses two tokens: MANA and LAND. MANA is an ERC-20 token that must be burned to acquire non-fungible ERC-721 LAND tokens. MANA tokens can also be used to pay for a range of avatars, wearables, names, and more on the Decentraland marketplace.

Decentraland (MANA) is a decentralized virtual world platform with software based on the Ethereum blockchain, where users create, test and monetize content. In short: users buy virtual plots of land as NFTs with MANA tokens on the Decentraland platform. Progress in the game depends only on players themselves, their efforts and their imagination.

The digital platform is completely owned by its users. Within the Decentraland metaverse, participants can explore the virtual world, purchase plots of land that can be monetized, create works of art, own non-fungible tokens (NFTs), and take part in a decentralized autonomous organization of the platform Decentraland DAO. Due to the DAO, the community influences the development vector of the project.

In addition, users have access to interactive applications, in-world payments and peer-to-peer communication. The 3D world resonates with many participants as Decentraland has many applications, both entertainment for gamers and business for investors.

Two types of tokens called MANA and LAND govern operations in Decentraland. They also allow users to interact with the platform.

MANA is the official currency of Decentraland. It’s an ERC-20 standard token that powers the Decentraland platform. With MANA, users can purchase plots of LAND, as well as pay for in-game items and services.

MANA gives its holders the right to vote in Decentraland DAO. MANA can be purchased on a cryptocurrency exchange or by selling collectibles on Decentraland Marketplace. The owner of tokens converts them to wrapped MANA, or wMANA, and then commits them to the DAO. One wMANA equals one vote. MANA can be exchanged for fiat currency and other digital assets.

As for LAND, it’s a non-fungible token (NFT) based on Ethereum (ETH). It is used to track ownership of land parcels aka digital real estate. Like MANA, LAND is part of the protocol and confers voting rights, but LAND does not need to be fixed in the DAO. One LAND is equal to two thousand votes.

Players choose what to do with their land. Owners store tokens in crypto wallets and buy necessities with MANA tokens on the Decentraland Marketplace. Moreover, on the marketplace, participants can manage or exchange LAND tokens (priced in MANA). Holders use the marketplace to transact or transfer in-game items. All transactions are conducted, regulated and registered via the Ethereum blockchain.

Decentraland combines an online gaming space and blockchain technology. All control over the rules is given to the players, and token holders vote on in-game and organizational policies. The original goal was to form a decentralized virtual reality, but in practice, Decentraland has turned into a massive NFT market.

A special role in Decentraland is assigned to NFTs, such as collectibles, virtual equipment and real estate (LAND). However, for new players who want to join the universe and seize NFTs, the entry barrier will be high.

The Decentraland protocol is built on three levels using Ethereum smart contracts. On the consensus layer, the ownership of LAND is tracked and managed. The land content layer displays the content of the Decentraland virtual world. Finally, on the real-time layer, participants interact with each other.

The platform was co-founded by two blockchain experts, Ari Meilich and Esteban Ordano, in 2015. Officially it was launched a year later and became available only in February 2020, gradually turning from a 2D experiment into a full-fledged 3D world.

To sum up, Decentraland is a decentralized game and a 3D virtual reality platform where players own lands and create limitlessly. Decentralized Autonomous Organization (DAO) software is at the core, and governance is in the hands of the community. Through the native token MANA, players participate in any proposals for managing and improving the ecosystem, the auction system, and the in-game policy.

The Graph is an indexing protocol for querying data for networks like Ethereum and IPFS, powering many applications in both DeFi and the broader Web3 ecosystem. Anyone can build and publish open APIs, called subgraphs, that applications can query using GraphQL to retrieve blockchain data. There is a hosted service in production that makes it easy for developers to get started building on The Graph and the decentralized network will be launching later this year. The Graph currently supports indexing data from Ethereum, IPFS and POA, with more networks coming soon.

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

To date, over3,000 subgraphs have been deployed by thousands of developers, for DApps like Uniswap, Synthetix, Aragon, AAVE, Gnosis, Balancer, Livepeer, DAOstack, Decentraland and many others. The Graph usage has been growing at over 50% MoM and hit over 7 billion queries during the month of September 2020.

The Graph has a global community, including over 200 Indexer Nodes in the testnet and more than 2,000 Curators in the Curator Program as of October 2020. To fund network development, The Graph raised funds from community members, strategic VCs and influential individuals in the blockchain community including Coinbase Ventures, DCG, Framework, ParaFi Capital, CoinFund, DTC, Multicoin, Reciprocal Ventures, SPC, Tally Capital and others. The Graph Foundation also successfully completed a public GRT Sale with participation from 99 countries (not including the U.S.). To date as of November 2020, The Graph has raised ~$25M.
