## ما هو بيتكوين كاش (BCH)؟

[بيتكوين كاش (BCH)](https://coinmarketcap.com/alexandria/article/bitcoin-vs-bitcoin-cash-vs-bitcoin-sv) هو نظام نقدي إلكتروني [من نظير إلى نظير](https://coinmarketcap.com/alexandria/article/what-is-peer-to-peer-p2p) الهدف منه إنشاء نظام نقدي عالمي صالح، يوفر خدمات دفع سريعة، ورسوم زهيدة، وخصوصية، وقدرة عالية على إجراء المعاملات (كتل بيانات كبيرة). وبالطريقة نفسها، التي تُسلَّم بها النقود العادية، مثل الدولارات إلى الشخص المدفوع لصالحه مباشرة، تُرسلُ مدفوعات بيتكوين كاش من شخص إلى آخر مباشرة.

وكعملة مشفرة غير مركزية، لا تحتاج إلى معالجة يدوية، لا تحتاج عملة بيتكوين كاش (BCH) أطراف ثالثة ضمن سلسلة الثقة، ولا يوجد لها بنك مركزي. كما أنها وخلافا للنقود التقليدية، لا تعتمد بيتكوين كاش على وسطاء النقد مثل المصارف ومعالجي الدفع. بهذا الشكل، لا يمكن أن تخضع المعاملات للرقابة من جانب الحكومات أو غيرها من الشركات المركزية. وبالتالي، لا يمكن مصادرة الأموال أو تجميدها — لأن الأطراف الثالثة المالية ليس لديها أي سيطرة على شبكة بيتكوين كاش.

### ما الغرض من استخدام بيتكوين كاش؟

تجمع عملة بيتكوين كاش (BCH) ما بين ميزة الندرة مثل الذهب وبين طبيعة النقد القابل للإنفاق. فمع تحديد سقف المعروض بـ 21 مليون عملة ققط، تصبح بيتكوين كاش نادرة، إضافة إلى إمكانية إنفاقها بسهولة، مثلها فى ذلك مثل النقود العادية، وتتميز المعاملات بالسرعة برسوم لا تتجاوز عادة عُشر سنت، ويمكن لأي شخصٍ قبول مدفوعات بيتكوين كاش باستخدام الهاتف الذكي أو الكمبيوتر.

عملة بيتكوين كاش له العديد من حالات الاستخدام، فإضافة إلى ميزة الدفع المباشر من نظير إلى نظير بين الأفراد، يمكن استخدام بيتكوين كاش للدفع للتجار المشاركين في هذا النظام، لقاء ما يقدمون من سلع وخدمات في متاجرهم العادية أو عبر الانترنت. حيث تمكّن الرسوم الزهيدة الأعمال ذات المعاملات متناهية الصغر، مثل دفع إكراميات لكتاب المحتوى أو دفع مكافآت قدرها بضع سنتات لمستخدمي تطبيقات المكافآت. كما تقلل بيتكوين كاش الرسوم، وأوقات معالجة التحويلات المالية، والمدفوعات التجارية العابرة للحدود. وتشمل حالات الاستخدام الأخرى الرموز المميزة، والعقود الذكية المبسطة، والمدفوعات الخاصة عبر أدوات، مثل كاش شفل (CashShuffle) وكاش فيوجن (CashFusion).

### هل تختلف بيتكوين كاش عن بيتكوين؟

انقسم مشروع بيتكوين ومجتمعه في عام 2017 إلى معسكرين؛ نتيجة مخاوف تتعلق بقابلية بيتكوين للتوسع. وكانت النتيجة تحديثٌ جذري في الشبكة، نتج عنه مولد عملة بيتكوين كاش، لتصبح عملة مشفرة جديدة يعتبرها مؤيدوها استمرارًا لمشروع بيتكوين بكونه [مال إلكتروني من نظير إلى نظير](http://bch.info/bitcoin.pdf). وأصبح جميع مالكي عملة بيتكوين عقب هذا التحديث (الكتلة 558,478) تلقائيًا مالكين لعملة بيتكوين كاش (BCH) أيضًا. لتبقى بيتكوين، التي ابتكرها الشخص صاحب الاسم المستعار[ساتوشي ناكاموتو](https://coinmarketcap.com/alexandria/article/who-is-satoshi-nakamoto)، عملة مشفرة مستقلة.

بخلاف بيتكوين ([BTC](https://coinmarketcap.com/ar-it/currencies/bitcoin/))، تهدف بيتكوين كاش (BCH) الى التوسع، بغية تلبية متطلبات نظام الدفع العالمي. حيث نجم عن هذا الانقسام، زيادة حجم كتلة بيتكوين كاش من 1 ميغابايت إلى 8 ميغابايت، وزيادة حجم الكتلة يعني أن بيتكوين كاش قادرة الآن على معالجة عدد أكبر بكثير من المعاملات في الثانية (TPS) -مع الحفاظ في الوقت نفسه على الرسوم في أقل قيمة لها- وحل مشكلات تأخيرات الدفع، والرسوم الباهظة التي يتعرض لها بعض مستخدمي شبكة بيتكوين BTC.

وبحلول أكتوبر 2021، وصل حجم كتلة بيتكوين كاش 32 ميجا بايت، مقارنة بحجم كتلة بيتكوين الذي يبلغ 1 ميجا بايت.

### كيف يمكن تعدين بيتكوين كاش؟

[التعدين](https://coinmarketcap.com/alexandria/glossary/mining) هو إجراءات تأكيد العمليات الجديدة الجارية على بيتكوين كاش، وذلك عبر إضافة كتل جديدة إلى سلسلة كتل بيتكوين كاش، حيث يستخدم المعدنون الطاقة الحاسوبية والكهرباء في حل معادلات معقدة، بعدها، تصبح لديهم قدرة على إنتاج كتل معاملات جديدة. فور قبول إحدى هذه الكتل البيانية من إحدى كيانات التعدين على الشبكة، يحصل هذا المعدّن، أو مجمّع التعدين على [مكافأة كتلة](https://coinmarketcap.com/alexandria/glossary/block-reward) والتي تأتي في شكل عملة بيتكوين كاش يتم سكها (ترميزها) حديثاً.

التعدين مجال عملٍ ذو منافسة شديدة، فمع ارتفاع سعر عملة بيتكوين كاش في السوق، يتسابق المزيد من المعدّنون للوصول إلى [معدل تجزئة](https://coinmarketcap.com/alexandria/glossary/hash-power-hash-rate) أكبر، وسط منافسة متزايدة ومستمرة بينهم، في إنتاج الكتل وقبولها على شبكة بيتكوين كاش. وزيادة أعداد من يقومون بالتعدين يسهمُ في تأمين الشبكة، من خلال زيادة معدل التجزئة وتوزيعه، الأمر الذي يؤدي إلى منع كيان تعدين واحد من التحكم في الشبكة.

بإمكان أي شخص تعدين بتكوين كاش، لكن التعدين يتطلب تجهيزات متخصصة تسمى معدات التعدين، وهي معدات يمكن شراؤها أو استئجارها. ويحتاج المعدّنون أيضًا إلى تشغيل أحد برمجيات العقدة الكاملة على الشبكة (يشغل معظم المعدنين حاليًا BCHN) من أجل بناء الكتل وربطها مع بقية شبكة بيتكوين كاش. ويمكن ممارسة التعدين بشكل مستقل، لكن يقوم المعدّنون غالبًا بتجميع معدلات التجزئة الخاصة بهم معًا؛ لتشكِّل قوة تنافسية أكبر، ثم يتقاسمون مكافآت الكتلة المكتسبة كل حسب نسبة مشاركته.

Litecoin (LTC) is a cryptocurrency that was designed to provide fast, secure and low-cost payments by leveraging the unique properties of blockchain technology.

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

The cryptocurrency was created based on the Bitcoin (BTC) protocol, but it differs in terms of the hashing algorithm used, hard cap, block transaction times and a few other factors. Litecoin has a block time of just 2.5 minutes and extremely low transaction fees, making it suitable for micro-transactions and point-of-sale payments.

Litecoin was released via an open-source client on GitHub on Oct. 7, 2011, and the Litecoin Network went live five days later on Oct. 13, 2011. Since then, it has exploded in both usage and acceptance among merchants and has counted among the top ten cryptocurrencies by market capitalization for most of its existence.

The cryptocurrency was created by Charlie Lee, a former Google employee, who intended Litecoin to be a "lite version of Bitcoin," in that it features many of the same properties as Bitcoin—albeit lighter in weight.

Litecoin

Ethereum Classic (ETC) is the original Ethereum (ETH) blockchain that launched in July 2015. Its main function is as a smart contract network, with the ability to host and support decentralized applications (DApps). Its native token is ETC.

Since its launch, Ethereum Classic has sought to differentiate itself from Ethereum, with the two networks’ technical roadmap diverging further and further from each other with time.

Ethereum Classic first set out to preserve the integrity of the existing Ethereum blockchain after a major hacking event led to the theft of 3.6 million ETH.

Ethereum Classic

TRON (TRX) is a decentralized blockchain-based operating system developed by the Tron Foundation and launched in 2017. Originally TRX tokens were ERC-20-based tokens deployed on Ethereum, but a year later they were moved to their own network.

Initially, the project was created with the aim of providing full ownership rights to makers of digital content. The main goal is to help content creators (who receive only a small part of the income) and encourage them with more rewards for their work. How: invite content consumers to reward content makers directly (without intermediaries like YouTube, Facebook or Apple).

The TRON software supports smart contracts, various kinds of blockchain systems, and decentralized applications aka dApps. The cryptocurrency platform uses a transaction model similar to Bitcoin (BTC), namely UTXO. Transactions take place in a public ledger, where users can track the history of operations.

Therefore, the platform was built to create a decentralized Internet and serves as a tool for developers to create dApps, acting as an alternative to Ethereum. Anyone can create dApps on the TRON network, offer content, and in return receive digital assets as compensation for their efforts. The ability to create content and share it openly without hesitation regarding transaction fees is an undeniable advantage of TRON.

TRON

Stellar (XLM) is a peer-to-peer (P2P) decentralized network created in 2014 by The Stellar Development Foundation or Stellar.org. The network officially launched in 2015 with the purpose of connecting the world's financial systems and ensuring a protocol for payment providers and financial institutions. The platform is designed to move financial resources swiftly and reliably at minimal cost. Stellar links people, banks, payment processors and allows users to create, send and trade multiple types of crypto.

The basis of the network is its native digital currency - XLM or Lumens. XLM acts as an intermediate currency for operations and is also used to pay transaction fees. How it works: the protocol converts money in a few seconds, first into XLM, and then into the requested currency.

The Stellar payment protocol is based on distributed ledger technology -- an open-source development, community-owned and distributed by community. The crypto asset of the Stellar platform helps with cross-border transactions, overcoming the problems of high fees and slow procedures. XLM is more focused on assisting individuals transfer money than they are with institutions. Thus, Stellar offers access to financial systems, and people can send money at low cost and promptly around the world.

Moreover, Stellar serves as a decentralized exchange and marketplace, with a built-in order book that tracks ownership of Stellar assets. Platform users can manage buy/sell orders, as well as select and set their preferred assets in settlements. XLM is a built-in coin that helps reduce transaction fees.

The network maintains a high level of security.  XLM holders must have at least one token in order to remain active on the network. This nuance performs a global goal - the execution of network transactions efficiently and with minimal time costs. Plus, Lumens offers protection against flood attacks by making microtransactions too expensive for hackers with no chance of profit, which keeps Stellar Network safe from serious threats.

The target audience of Stellar is the inhabitants of developing countries, ordinary users who are provided access to the global economy through fast, simple and inexpensive transactions. Stellar Network makes extensive use of Lumens to produce live convection as well as to send cash in multiple currencies; currency is sent from one peer, and the recipient can receive the amount in another currency. This feature is beneficial when a transaction is made between currencies without widely traded pairs.

Support for multi-currency transactions is another competitive advantage of Stellar, and the ability for cross-currency transactions has only enhanced processes with foreign operations. Moreover, stable speed and low transaction costs are a privilege that users receive.

This functionality is powered by a development called Anchors (a bridge between different currencies and the network), which simplifies the exchange within the network and helps speed up the whole process.

In summary, the benefits of Stellar (XLM) include:

Stellar

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.

Uniswap

Launched in 2021, the XRP Ledger (XRPL) is an open-source, permissionless and decentralized technology. Benefits of the XRP Ledger include its low-cost ($0.0002 to transact), speed  (settling transactions in 3-5 seconds), scalability (1,500 transactions per second) and inherently green attributes (carbon-neutral and energy-efficient). The XRP Ledger also features the first decentralized exchange (DEX) and custom tokenization capabilities built into the protocol. Since 2012, the XRP Ledger has been operating reliably, having closed 70 million ledgers.

Dogecoin (DOGE) is based on the popular "doge" Internet meme and features a Shiba Inu on its logo. The open-source digital currency was created by Billy Markus from Portland, Oregon and Jackson Palmer from Sydney, Australia, and was forked from Litecoin in December 2013. Dogecoin's creators envisaged it as a fun, light-hearted cryptocurrency that would have greater appeal beyond the core Bitcoin audience, since it was based on a dog meme. Tesla CEO Elon Musk posted several tweets on social media that Dogecoin is his favorite coin.

The EOS Network is an open-source blockchain platform that prioritizes high performance, flexibility, security, and developer experience. As a third-generation blockchain platform powered by the EOS virtual machine, EOS has an extensible WebAssembly engine for deterministic execution of near fee-less transactions.

EOS is the market's most scalable, divisible, and programmable digital currency. EOS is a Delegated Proof of Stake (DPoS) network where stakeholders have the authority to select node operators. Due to the decentralized nature of the token distribution on EOS, power doesn't reside in the hands of block miners, but rather all parties involved in the EOS Network.

The EOS Network is attractive because of its technology and community. It allows developers to build projects that other blockchains cannot support. The network is straightforward and has multiple tools and educational resources to help users acclimate to the blockchain.

Monero was launched in 2014, and its goal is simple: to allow transactions to take place privately and with anonymity. Even though it’s commonly thought that BTC can conceal a person’s identity, it’s often easy to trace payments back to their original source because blockchains are transparent. On the other hand, XMR is designed to obscure senders and recipients alike through the use of advanced cryptography.

The team behind Monero say privacy and security are their biggest priorities, with ease of use and efficiency coming second. It aims to provide protection to all users — irrespective of how technologically competent they are.

Overall, XMR aims to allow payments to be made quickly and inexpensively without fear of censorship.

Monero

Founded in 2017, Chainlink is a blockchain abstraction layer that enables universally connected smart contracts. Through a decentralized oracle network, Chainlink allows blockchains to securely interact with external data feeds, events and payment methods, providing the critical off-chain information needed by complex smart contracts to become the dominant form of digital agreement.

The Chainlink Network is driven by a large open-source community of data providers, node operators, smart contract developers, researchers, security auditors and more. The company focuses on ensuring that decentralized participation is guaranteed for all node operators and users looking to contribute to the network.

Cardano is a proof-of-stake blockchain platform that says its goal is to allow “changemakers, innovators and visionaries” to bring about positive global change.

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

The open-source project also aims to “redistribute power from unaccountable structures to the margins to individuals” — helping to create a society that is more secure, transparent and fair.

Cardano was founded back in 2017, and named after the 16th century Italian polymath Gerolamo Cardano. The native ADA token takes its name from the 19th century mathematician Ada Lovelace, widely regarded as the world’s first computer programmer. The ADA token is designed to ensure that owners can participate in the operation of the network. Because of this, those who hold the cryptocurrency have the right to vote on any proposed changes to the software.

The team behind the layered blockchain say that there have already been some compelling use cases for its technology, which aims to allow decentralized apps and smart contracts to be developed with modularity.

In August 2021, Charles Hoskinson announced the launch of the Alonzo hard fork, causing Cardano price to surge, gaining 116% in the following month. On Sept. 12, 2021, the Cardano ‘Alonzo’ hard fork officially launched, bringing smart contract functionality to the blockchain. Over 100 smart contracts were deployed in the following 24 hours after the launch.

Cardano is used by agricultural companies to track fresh produce from field to fork, while other products built on the platform allow educational credentials to be stored in a tamper-proof way, and retailers to clamp down on counterfeit goods.

Cardano

Bitcoin SV (BSV) emerged following a hard fork of the Bitcoin Cash (BCH) blockchain in 2018, which had in turn forked from the BTC blockchain a year earlier following the blocksize wars.

BSV claims to fulfill the original vision of the Bitcoin protocol and design as described in Satoshi Nakamoto’s white paper, early Bitcoin client software and known Satoshi writings. BSV aims to offer scalability and stability in line with the original description of Bitcoin as a peer-to-peer electronic cash system, as well as deliver a distributed data network that can support enterprise-level advanced blockchain applications.

To this end, it has removed artificial block size limits and re-enabled Script commands and other technical capabilities which had been historically disabled or restricted by the protocol developers of the BTC blockchain. This purportedly allows the network to process tens of thousands of transactions per second while maintaining extremely low transaction fees for micropayments, in addition to offering advanced capabilities such as tokens, smart contracts, computation and other data use cases.

The BSV network claims to be unique in its capacity for unbounded on-chain scaling while also being more aligned with the original design of Bitcoin than any other blockchain.

Bitcoin SV

Polkadot is an open-source sharded multichain protocol that connects and secures a network of specialized blockchains, facilitating cross-chain transfer of any data or asset types, not just tokens, thereby allowing blockchains to be interoperable with each other. Polkadot was designed to provide a foundation for a decentralized internet of blockchains, also known as Web3.

Polkadot is known as a layer-0 metaprotocol because it underlies and describes a format for a network of layer 1 blockchains known as parachains (parallel chains). As a metaprotocol, Polkadot is also capable of autonomously and forklessly updating its own codebase via on-chain governance according to the will of its token holder community.

Polkadot provides a foundation to support a decentralized web, controlled by its users, and to simplify the creation of new applications, institutions and services.

The Polkadot protocol can connect public and private chains, permissionless networks, oracles and future technologies, allowing these independent blockchains to trustlessly share information and transactions through the Polkadot Relay Chain (explained further down).

Polkadot’s native DOT token serves three clear purposes: staking for operations and security, facilitating network governance, and bonding tokens to  connect parachains .

Polkadot has four core components:

Relay Chain: Polkadot’s “heart,” helping to create consensus, interoperability and shared security across the network of different chains;

Parachains: independent chains that can have their own tokens and be optimized for specific use cases;

Parathreads: similar to parachains but with flexible connectivity based on an economical pay-as-you-go model;

Bridges: allow parachains and parathreads to connect and communicate with external blockchains like Ethereum.

Polkadot

Launched in July 2017, Binance is the biggest cryptocurrency exchange globally based on daily trading volume. Binance aims to bring cryptocurrency exchanges to the forefront of financial activity globally. The idea behind Binance’s name is to show this new paradigm in global finance — Binary Finance, or Binance.

Aside from being the largest cryptocurrency exchange globally, Binance has launched a whole ecosystem of functionalities for its users. The Binance network includes the Binance Chain, Binance Smart Chain, Binance Academy, Trust Wallet and Research projects, which all employ the powers of blockchain technology to bring new-age finance to the world. BNB is an integral part of the successful functioning of many of the Binance sub-projects.

Dash is an open-source blockchain and cryptocurrency focused on offering a fast, cheap global payments network that is decentralized in nature. According to the project's white paper, Dash seeks to improve upon Bitcoin (BTC) by providing stronger privacy and faster transactions.

Dash, whose name comes from "digital cash," was launched in January 2014 as a fork of Litecoin (LTC). Since going live, Dash has grown to include features such as a two-tier network with incentivized nodes, including "masternodes," and decentralized project governance; InstantSend, which allows for instantly settled payments; ChainLocks, which makes the Dash blockchain instantly immutable; and PrivateSend, which offers additional optional privacy for transactions.

Dash

Ethereum is a decentralized open-source blockchain system that features its own cryptocurrency, Ether. ETH works as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.

Ethereum was first described in a 2013 whitepaper by Vitalik Buterin. Buterin, along with other co-founders, secured funding for the project in an online public crowd sale in the summer of 2014. The project team managed to raise $18.3 million in Bitcoin, and Ethereum’s price in the Initial Coin Offering (ICO) was $0.311, with over 60 million Ether sold. Taking Ethereum’s price now, this puts the return on investment (ROI) at an annualized rate of over 270%, essentially almost quadrupling your investment every year since the summer of 2014.

The Ethereum Foundation officially launched the blockchain on July 30, 2015, under the prototype codenamed “Frontier.” Since then, there has been several network updates — “Constantinople” on Feb. 28, 2019, “Istanbul” on Dec. 8, 2019, “Muir Glacier” on Jan. 2, 2020, “Berlin” on April 14, 2021, and most recently on Aug. 5, 2021, the “London” hard fork.

Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime and fraud.

Ethereum

Zcash is a decentralized cryptocurrency focused on privacy and anonymity. It uses the zk-SNARK zero-knowledge proof technology that allows nodes on the network to verify transactions without revealing any sensitive information about those transactions.

Contrary to a common misunderstanding, the majority of cryptocurrencies on the market, including Bitcoin (BTC), are not anonymous, but rather pseudonymous; while they do not explicitly reveal the identities of their users, each user has their own public address or addresses which can be traced back to them via the methods of data science and blockchain forensics.

Zcash transactions, on the other hand, still have to be relayed via a public blockchain, but unlike pseudonymous cryptocurrencies, ZEC transactions by default do not reveal the sending and receiving addresses or the amount being sent. There is an option, however, to reveal this data for the purposes of auditing or regulatory compliance.

Zcash was first released on October 28, 2016, and it was originally based on Bitcoin’s codebase.

Zcash

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

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.

Polygon

Solana is a highly functional open source project that banks on blockchain technology’s permissionless nature to provide decentralized finance (DeFi) solutions. While the idea and initial work on the project began in 2017, Solana was officially launched in March 2020 by the Solana Foundation with headquarters in Geneva, Switzerland.

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

The Solana protocol is designed to facilitate decentralized app (DApp) creation. It aims to improve scalability by introducing a proof-of-history (PoH) consensus combined with the underlying proof-of-stake (PoS) consensus of the blockchain.

Because of the innovative hybrid consensus model, Solana enjoys interest from small-time traders and institutional traders alike. A significant focus for the Solana Foundation is to make decentralized finance accessible on a larger scale.
