## ما هي ستاكس (STX)؟

ستاكس (Stacks) هي حل طبقة أولى على سلسلة الكتل، وقد تم تصميمها من أجل جلب العقود الذكية والتطبيقات اللامركزية ([DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps)) إلى [بيتكوين (BTC)](https://coinmarketcap.com/ar/currencies/bitcoin/). حيث تهدف لتوفير هذه العقود الذكية لبيتكوين دون تغيير أي من الميزات التي تجعلها قوية للغاية — بما في ذلك أمنها واستقرارها.

وتتميّز التطبيقات اللامركزية بأنها مفتوحة المصدر، مما يعني أن المطورين يمكنهم البناء على تطبيقات بعضهم البعض لإنتاج ميزات غير ممكنة ببساطة في التطبيق العادي. ونظراً لأن ستاكس تستخدم بيتكوين كطبقة أساسية، فإن كل ما يحدث على الشبكة يتم تسويته ضمن أكثر السلاسل استخداماً على نطاق واسع كما يمكن القول إنها [سلسلة الكتل](https://coinmarketcap.com/alexandria/glossary/blockchain) الأكثر أماناً في التشغيل — بيتكوين.

يتم تشغيل المنصة بواسطة رمزها المشفر ستاكس (STX)، والذي يستخدم لتغذية تنفيذ العقود الذكية ومعالجة المعاملات وتسجيل الأصول الرقمية الجديدة على سلسلة كتل ستاكس 2.0.

كانت المنصة تُعرف سابقاً باسم "Blockstack"، ولكن تم إعادة تسميتها إلى ستاكس في الربع الرابع من عام 2020 من أجل "فصل مشروع النظام البيئي والمصدر المفتوح عن Blockstack PBC" — الشركة التي بنت البروتوكولات الأصلية.

تم إطلاق الشبكة الرئيسية لستاكس 2.0 في يناير 2021.

### من هم مؤسسو ستاكس؟

تم تمويل ستاكس في البداية من قبل مجموعة من صناديق رأس المال الاستثماري البارزة، بما في ذلك Y Combinator، وDigital Currency Group، وWinklevoss Capital. وقد تم تطويرها من قبل "Blockstack PBC"، التي يقع مقرها في نيويورك.

يذكر أن "Blockstack PBC" باتت تعمل الآن تحت اسم "Hyro Systems PBC"، إلى جانب مجموعة واسعة من الشركات التي تبني على منصة ستاكس.

تأسست "Blockstack PBC" من قبل منيب علي، وريان شيا. بعد التخرج من جامعة برينستون مع درجة الماجستير والدكتوراه في علوم الكمبيوتر، شارك منيب علي في تأسيس ستاكس في عام 2013، ولا يزال يعمل مع المنصة اليوم بصفته الرئيس التنفيذي لشركة "Hiro Systems PBC".

أمّا المؤسس المشارك الثاني للمنصة، ريان شي، فقد شغل منصب الرئيس التنفيذي المشارك بين عامي 2013 و2018، قبل مغادرة من المشروع لمتابعة مشاريع أخرى — بما في ذلك المشاركة في تأسيس شركة تقنية ناشئة جديدة تعمل حالياً خارج الأضواء. قبل وظيفته في ستاكس، عمل شيا كمهندس برمجيات.

### ما الذي يميّز ستاكس؟

تهدف ستاكس إلى جعل بيتكوين قوية للغاية، عبر تزويدها بوظائف إضافية، دون الحاجة إلى انقسام (شوكة) في سلسلة بيتكوين الأصلية أو تغييرها.

وهي تقوم بذلك من خلال خلق ربط مباشر مع سلسلة الكتل بيتكوين من خلال [آلية إجماع](https://coinmarketcap.com/alexandria/glossary/consensus) إثبات النقل (PoX)، والتي تستوجب من المعدّنين الدفع في BTC من أجل سكّ (ترميز) رموز ستاكس المشفّرة الجديدة (STX). علاوة على ذلك، يمكن لحاملي رموز STX أيضاً تكديس ( *وليس* [*التخزين المؤقت*](https://coinmarketcap.com/alexandria/glossary/staking)) لرموزهم المشفّرة من أجل كسب بيتكوين كمكافأة.

حيث توفّر ستاكس لغة برمجة جديدة للعقود الذكية معروفة باسم "كلاريتي"، والتي تم تصميمها لتكون آمنة وسهلة البناء بفضل بناء الجملة الذي لا لبس فيه. تُستخدم لغة البرمجة الذكية التي تتمحور حول العقود أيضاً بواسطة سلسلة كتل [ألغوراند (ALGO)](https://coinmarketcap.com/ar/currencies/algorand/).

علاوة على ذلك، كانت ستاكس أول عملة مشفرة تحصل على ترخيص لجنة الأوراق المالية لتداولها في الولايات المتحدة، وهو ما سمح لها بإطلاق طرح نقدي بقيمة 28 مليون دولار أمريكي لرموز STX المشفّرة في يوليو 2019.

### كم عدد عملات ستاكس (STX) الموجودة في التداول؟

وفقاً للسياسة الاقتصادية التي تم تجديدها مؤخراً والتي تم إطلاقها مع إعلان ستاكس 2.0، سيتم تخفيض المعروض المتداول من STX بحوالي 10% حتى عام 2020 مقارنة بالجدول الزمني الأصلي.

في المجموع، من المتوقع أن يكون حوالي 1.82 مليار STX متداولة بحلول عام 2050، مقارنة بنحو 739.7 مليون متداولة بحلول يناير 2021.

وفقاً لمسودة [المستند الفني التعريفي (الورقة البيضاء) لستاكس 2.0 (الإصدار 0.1)](https://gaia.blockstack.org/hub/1AxyPunHHAHiEffXWESKfbvmBpGQv138Fp/stacks.pdf)، سيتم إطلاق ما مجموعه 1000 STX كمكافئة كتلة في السنوات الأربع الأولى، ثم ينخفض ذلك إلى 500 STX/كتلة في السنوات الأربع التالية، و250 STX/كتلة في السنوات الأربع المقبلة، ثم 120 STX/كتلة بعد ذلك إلى الأبد.

في المجموع، تم تخصيص 6.6% من إمدادات التكوين الأولية (1.32 مليار STX) للمؤسس و7.9% أخرى لفريق ستاكس. تخضع هذه المخصصات لجدول زمني للإفراج عنها مدته ثلاث سنوات، ومن المقرر الإفراج عن الرموز المشفّرة في نوفمبر 2021.

### كيف يتم تأمين شبكة ستاكس؟

تستخدم ستاكس سلسلة كتل بيتكوين كطبقة أساسية لها. وباعتبارها مؤمنة باستخدام آلية [إثبات العمل](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake)، تستخدم بيتكوين الجهود المشتركة لآلاف المعدّنين ومشغلي العقد لحماية الشبكة من [الهجمات](https://coinmarketcap.com/alexandria/glossary/51-attack) وذلك عبر جعلها غير مجدية حسابياً واقتصادياً للمهاجمين.

علاوة على ذلك، تقدم ستاكس نموذج التوافق الخاص بها، والمعروف باسم إثبات النقل (PoX)، وهو آلية تعدين جديدة تكافئ المستخدمين الذين ينقلون العملة الأساسية (BTC) بتعدين STX — مما يؤدي بشكل فعال إلى تعزيز أمن سلسلة كتل ستاكس باستخدام BTC.

### أين يمكنك شراء ستاكس (STX)؟

STX متاحة للتداول على العديد من منصات التبادل البارزة، بما في ذلك [Binance](https://coinmarketcap.com/ar/exchanges/binance/)، وKuCoin. للحصول على قائمة كاملة بأزواج التداول المتاحة والمنصات المدعومة، ارجع إلى [قسم الأسواق](https://coinmarketcap.com/ar/currencies/stacks/markets/).

RenderToken (RNDR) is a distributed GPU rendering network built on top of the Ethereum blockchain, aiming to connect artists and studios in need of GPU compute power with mining partners willing to rent their GPU capabilities out. Conceived in 2009 by OTOY, inc. CEO Jules Urbach and launched in 2017, RNDR held its first public token sale in October of that same year, followed by a private sale period lasting from January 2018 – May 2018, wherein a total of 117,843,239 RNDR were sold at a price of 1 RNDR = $0.25 USD equivalent of token.
During the private sale period, early adopters were onboarded onto the RNDR Beta Testnet, where beta node operators and artists worked collaboratively with the RNDR team in building and testing the network, up until its public launch on April 27th 2020.

Injective is a blockchain built for finance. It is an open, interoperable layer-one blockchain powering next-generation DeFi applications, including decentralized spot and derivatives exchanges, prediction markets, lending protocols and more.

Injective uniquely provides powerful core financial infrastructure primitives that applications can leverage, including a fully decentralized MEV-resistant on-chain orderbook. In addition, all forms of financial markets such as spot, perpetual, futures and options are fully on-chain. The decentralized cross-chain bridging infrastructure is compatible with Ethereum, IBC-enabled blockchains, and non EVM chains such as Solana.

Injective also provides a next-generation, highly interoperable smart contract platform based on CosmWasm, with advanced interchain capabilities. Injective is custom built with the Cosmos SDK and utilizes Tendermint-based Proof-of-Stake consensus mechanism, providing instant transaction finality with the ability to sustain lightning-fast performance (10,000+ TPS).

The Injective ecosystem includes 100+ projects and over 150,000 community members globally. Injective is backed by a group of prominent investors such as Binance, Pantera Capital, Jump Crypto and Mark Cuban.

Injective’s core exchange module provides state-of-the-art capabilities including an advanced on-chain order book and matching engine for spot, perpetual, futures and options markets, resistance to Miner-Extractable Value (MEV) through frequent batch auction order matching, and zero gas fees for users.

Injective natively uses IBC and is highly-interoperable with multiple layer 1s, including, but not limited to, Polygon and Solana (through an upcoming Wormhole integration). It is also uniquely built to be interoperable with Ethereum, through its own decentralized ERC-20 token bridge, making Injective the first network within the Cosmos ecosystem to natively support Ethereum assets.

Smart contracts are implemented on Injective through CosmWasm, allowing for multi-chain smart contract transactions to occur seamlessly. Injective, however, is the only blockchain that enables automatic smart contract execution. This capability serves as a powerful building block for developers to create novel use cases that would not be possible on any other chain.

The use cases intended for INJ include but are not limited to: protocol governance, dApp value capture, Proof-of-Stake (PoS) security, developer incentives and staking. Further details regarding each of these use cases can be found below:

Protocol Governance: The INJ token governs every single component of Injective, including chain upgrades. Since its mainnet launch, the Injective community has actively contributed to governance, with all proposals passing through a DAO governance vote. The comprehensive governance page is available here.

Protocol Fee Value Capture: 60% of all fees generated from dApps enter an on-chain buy-back-and-burn auction to maintain the deflationary nature of INJ. The burn auction page is available here.

Tendermint-based Proof-of-Stake (PoS) Security: INJ is used to secure the Injective blockchain using a proof-of-stake mechanism. Validators and delegators can both participate in staking.

Developer Incentives: 40% of fees generated by users on dApps built on Injective go directly towards incentivizing new developers building on Injective which brings an ever growing funnel of builders to Injective.

Immutable positions itself as the first layer-two scaling solution for NFTs on Ethereum. According to Immutable, its blockchain does away with Ethereum’s limitations like low scalability, a poor user experience, illiquidity, and a slow developer experience. Instead, users benefit from instant trading and massive scalability while enjoying zero gas fees for minting and trading NFTs without compromising user or asset security.

Thanks to this technology, users will be able to create and distribute assets like ERC-20 and ERC-721 tokens on a massive scale. Chris Clay, the game Director of Gods Unchained, a project already building on Immutable, stated that Immutable allows Gods Unchained to implement a new meta-system that was previously impossible. In this fashion, Immutable aims to create a world-class experience for users and developers alike.

Immutable

NEAR Protocol is a layer-one blockchain that was designed as a community-run cloud computing platform and that eliminates some of the limitations that have been bogging competing blockchains, such as low transaction speeds, low throughput and poor interoperability. This provides the ideal environment for DApps and creates a developer and user-friendly platform. For instance, NEAR uses human-readable account names, unlike the cryptographic wallet addresses common to Ethereum. NEAR also introduces unique solutions to scaling problems and has its own consensus mechanism called “Doomslug.”

NEAR Protocol is being built by the NEAR Collective, its community that is updating the initial code and releasing updates to the ecosystem. Its declared goal is to build a platform that is “secure enough to manage high value assets like money or identity and performant enough to make them useful for everyday people.”

Flux, a protocol that allows developers to create markets based on assets, commodities, real-world events, and Mintbase, an NFT minting platform are examples of projects being built on NEAR Protocol.

NEAR Protocol

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.

Founded in 2017 and launched via IEO on Binance in March 2019, Fetch.AI is an artificial intelligence (AI) lab building an open, permissionless, decentralized machine learning network with a crypto economy. Fetch.ai democratizes access to AI technology with a permissionless network upon which anyone can connect and access secure datasets by using autonomous AI to execute tasks that leverage its global network of data. The Fetch.AI model is rooted in  use cases like optimizing DeFi trading services, transportation networks (parking, micromobility), smart energy grids, travel — essentially any complex digital system that relies on large-scale datasets.

Fetch.ai

Avalanche is a layer one blockchain that functions as a platform for decentralized applications and custom blockchain networks. It is one of Ethereum’s rivals, aiming to unseat Ethereum as the most popular blockchain for smart contracts. It aims to do so by having a higher transaction output of up to 6,500 transactions per second while not compromising scalability.

This is made possible by Avalanche’s unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain. Each chain has a distinct purpose, which is radically different from the approach Bitcoin and Ethereum use, namely having all nodes validate all transactions. Avalanche blockchains even use different consensus mechanisms based on their use cases.

After its mainnet launch in 2020, Avalanche has worked on developing its own ecosystem of DApps and DeFi. Different Ethereum-based projects such as SushiSwap and TrueUSD have integrated with Avalanche. Furthermore, the platform is constantly working on improving interoperability between its own ecosystem and Ethereum, like through the development of bridges.

Avalanche

Filecoin is a decentralized storage system that aims to “store humanity’s most important information.” The project raised $205 million in an initial coin offering (ICO) in 2017, and initially planned a launch date for mid-2019. However, the launch date for the Filecoin mainnet was pushed back until block 148,888, which is expected in mid-October 2020.

The project was first described back in 2014 as an incentive layer for the Interplanetary File System (IPFS), a peer-to-peer storage network where users pay for data storage and distribution services in $FIL. Filecoin is open protocol and backed by a blockchain that records commitments made by the network’s participants, with transactions made using FIL, the blockchain’s native currency. The blockchain is based on both proof-of-replication and proof-of-spacetime.

Filecoin is open-source and decentralized, which means that all governance is in the hands of the community. On the Filecoin platform, developers have the opportunity to create cloud file storage services like Dropbox or iCloud. Anyone can join Filecoin and start storing their data or earn money by providing space for someone else's funds. The creators of Filecoin opted for their blockchain technology to run the network and their token with their own consensus.

$FIL is the native currency of Filecoin that powers the entire network and all processes. Clients pay for transactions in FIL tokens. Miners place FIL as collateral, guaranteeing their services.

The developers claim that Filecoin solves the problem of inefficient file storage and retrieval. Customers can find the right solution with an efficient set of tools and its core development, IPFS.

Filecoin

Arweave is a decentralized storage network that seeks to offer a platform for the indefinite storage of data. Describing itself as "a collectively owned hard drive that never forgets," the network primarily hosts "the permaweb" — a permanent, decentralized web with a number of community-driven applications and platforms.

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

The Arweave network uses a native cryptocurrency, AR, to pay "miners" to indefinitely store the network's information.

The project was first announced as Archain in August 2017, later rebranding to Arweave in February 2018 and officially launching in June 2018.

Arweave

Optimism (OP) is a layer-two blockchain on top of Ethereum. Optimism benefits from the security of the Ethereum mainnet and helps scale the Ethereum ecosystem by using optimistic rollups. That means transactions are trustlessly recorded on Optimism but ultimately secured on Ethereum.

Optimism is one of the biggest scaling solutions for Ethereum with over $500 million in TVL. It is home to 97 protocols, the biggest being Synthetix (SNX), a derivatives exchange, Uniswap (UNI), a DEX, and Velodrome (VELO), an AMM. Users can begin their journey on Optimism by adding the chain on their Metamask and bridging tokens like ETH to the L2. On May 31, 2022, Optimism conducted a highly anticipated airdrop of its OP token.

Optimism

THORChain is a decentralized liquidity protocol that allows users to easily exchange cryptocurrency assets across a range of networks including Bitcoin and Ethereum without losing full custody of their assets in the process.

With THORChain, users can simply swap one asset for another in a permissionless setting, without needing to rely on order books to source liquidity. Instead, market prices are maintained through the ratio of assets in a pool (see automated market maker.

The native utility token of the THORChain platform is RUNE. This is used as the base currency in the THORChain ecosystem and is also used for platform governance and security as part of THORChain's Sybil resistance mechanisms — since THORChain nodes must commit a minimum of 300k RUNE to participate in its rotating consensus process.

THORChain was funded through an initial DEX offering (IDO) which launched through the Binance DEX in July 2019. Its single-chain chaosnet launched in April 2021, the multi-chain upgrade was launched in April 2021 and Mainnet is now live as of Jun 2022..

Polygon (previously Matic Network) is the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development. Its core component is Polygon SDK, a modular, flexible framework that supports building multiple types of applications.

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

Using Polygon, one can create optimistic rollup chains, ZK rollup chains, stand alone chains or any other kind of infra required by the developer.

Polygon effectively transforms Ethereum into a full-fledged multi-chain system (aka Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc. with the advantages of Ethereum’s security, vibrant ecosystem and openness.

The $MATIC token will continue to exist and will play an increasingly important role, securing the system and enabling governance.

Polygon (formerly Matic Network) is a Layer 2 scaling solution backed by Binance and Coinbase. The project seeks to stimulate mass adoption of cryptocurrencies by resolving the problems of scalability on many blockchains.

Polygon combines the Plasma Framework and the proof-of-stake blockchain architecture. The Plasma framework used by Polygon as proposed by the co-founder of Ethereum, Vitalik Buterin, allows for the easy execution of scalable and autonomous smart contracts.

Nothing will change for the existing ecosystem built on the Plasma-POS chain. With Polygon, new features are being built around the existing proven technology to expand the ability to cater to diverse needs from the developer ecosystem. Polygon will continue to develop the core technology so that it can scale to a larger ecosystem.

Polygon boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds. The framework also allows for the creation of globally available decentralized financial applications on a single foundational blockchain.

The Plasma framework gives Polygon the potential of housing an unlimited number of decentralized applications on their infrastructure without experiencing the normal drawbacks common on proof-of-work blockchains. So far, Polygon has attracted more than 50 DApps to its PoS-secured Ethereum sidechain.

MATIC, the native tokens of Polygon, is an ERC-20 token running on the Ethereum blockchain. The tokens are used for payment services on Polygon and as a settlement currency between users who operate within the Polygon ecosystem. The transaction fees on Polygon sidechains are also paid in MATIC tokens.

In a nutshell, Cosmos bills itself as a project that solves some of the “hardest problems” facing the blockchain industry. It aims to offer an antidote to “slow, expensive, unscalable and environmentally harmful” proof-of-work protocols, like those used by Bitcoin, by offering an ecosystem of connected blockchains.

The project’s other goals include making blockchain technology less complex and difficult for developers thanks to a modular framework that demystifies decentralized apps. Last but not least, an Interblockchain Communication protocol makes it easier for blockchain networks to communicate with each other — preventing fragmentation in the industry.

Cosmos’ origins can be dated back to 2014, when Tendermint, a core contributor to the network, was founded. In 2016, a white paper for Cosmos was published — and a token sale was held the following year. ATOM tokens are earned through a hybrid proof-of-stake algorithm, and they help to keep the Cosmos Hub, the project’s flagship blockchain, secure. This cryptocurrency also has a role in the network’s governance.

Cosmos

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

Synthetix is building a decentralized liquidity provisioning protocol that any protocol can tap into for various purposes. Its deep liquidity and low fees serve as a backend for many exciting protocols on both Optimism and Ethereum. Many user-facing protocols in the Synthetix ecosystem, such as Kwenta (Spot and Futures), Lyra (Options), Polynomial (Automated Options), and 1inch & Curve (Atomic Swaps), tap into Synthetix liquidity to power their protocols. Synthetix is built on Optimism and Ethereum mainnet. The Synthetix Network is collateralized by SNX, ETH, and LUSD, enabling the issuance of synthetic assets (Synths). Synths track and provide returns on the underlying asset without requiring one to directly hold the asset. This pooled collateral enables an array of on-chain, composable financial instruments backed by liquidity from Synthetix. Some of the most exciting upcoming releases from SNX are Perps V2, which hopes to enable low-fee on-chain futures trading through the usage of off-chain oracles, and Synthetix V3, which aims to rebuild the protocol to achieve its earliest goal, being a fully permissionless derivatives protocol. Learn more about Synthetix on their blog or by joining the SNX Discord.

The platform aims to broaden the cryptocurrency space by introducing non-blockchain assets, providing access to a more robust financial market.

The Internet Computer blockchain incorporates a radical rethink of blockchain design, powered by innovations in cryptography. It provides the first “World Computer” blockchain that can be used to build almost any online system or service, including demanding web social media, without need for traditional IT such as cloud computing services. As such it can enable full end-to-end decentralization.

Uniswap is a popular decentralized trading protocol, known for its role in facilitating automated trading of decentralized finance (DeFi) tokens.

An example of an automated market maker (AMM), Uniswap launched in November 2018, but has gained considerable popularity this year thanks to the DeFi phenomenon and associated surge in token trading.

Uniswap aims to keep token trading automated and completely open to anyone who holds tokens, while improving the efficiency of trading versus that on traditional exchanges.

Uniswap creates more efficiency by solving liquidity issues with automated solutions, avoiding the problems which plagued the first decentralized exchanges.

In September 2020, Uniswap went a step further by creating and awarding its own governance token, UNI, to past users of the protocol. This added both profitability potential and the ability for users to shape its future — an attractive aspect of decentralized entities.
