## ما هو البيتكوين المُغلف (WBTC)؟

إنّ البيتكوين المغلف نسخة رمز من [Bitcoin](https://coinmarketcap.com/ar/currencies/bitcoin/)(BTC) تعمل على سلسلة كتل [Ethereum](https://coinmarketcap.com/ar/currencies/ethereum/)(ETH).

يتوافق البيتكوين المُغلف (WBTC) مع رمز ERC-20 — معيار التوافق الأساسي لسلسلة كتل Ethereum — مما يسمح بدمجها بالكامل في النظام البيئي الخاص بمنصات التداول اللامركزية وخدمات الإقراض المشفرة وأسواق التنبؤ وغيرها من تطبيقات التمويل اللامركزي (DeFi) المُستندة إلى رمز ERC-20.

يتلقى البيتكوين المُغلف (WBTC) الدعم من Bitcoin أيضًا بنسبة 1:1 عبر شبكة من التجار وأمناء الاستثمار الذين يخضعون للمراقبة تلقائيًا، مما يضمن أن سعره مرتبط بعملة Bitcoin في جميع الأوقات ويسمح للمستخدمين بنقل السيولة بين BTC وشبكات ETH بشكل لامركزي و بطريقة مستقلة.

تم الإعلان عن البيتكوين المُغلف لأول مرة في 26 أكتوبر 2018، وتم إطلاقه رسميًا في 31 يناير 2019.

### من هم مُؤسسو البيتكوين المغلف (WBTC)؟

إن مشروع الرموز المُغلفة (Wrapped Tokens)، الذي يُعد البيتكوين المُغلف (WBTC) جزءًا منه، لم يتم تأسيسه من قبل الأفراد ولكنه مشروع مشترك لثلاث مؤسسات: BitGo و شبكة Kyber و [Ren](https://coinmarketcap.com/ar/currencies/ren/).

إنّ BitGo، والتي أسسها عالم الكمبيوتر ورائد الأعمال الأمريكي مايك بيلشي في عام 2013، هي شركة حفظ الأصول الرقمية والتداول والخدمات المالية. فضلاً عن كونها أحد مطوري البيتكوين المُغلف (WBTC)، تعمل BitGo أيضًا كحافظ أصلي لها — الكيان الذي يحتفظ برموز (WBTC) والمفاتيح اللازمة لسك المزيد منها.

إنّ شبكة Kyber عبارة عن بروتوكول سيولة مُستند على سلسلة الكتل، يُتيح دمج رموز العملات المشفرة وتطبيقات التمويل اللامركزي (DeFi). تأسست الشبكة في عام 2017 من قبل لوي لو وفيكتور ترانو ويارون فيلنر ومقرها في سنغافورة. جنبًا إلى جنب مع Ren، ساعدت شبكة Kyber في إنشاء البيتكوين المُغلف (WBTC) ولا تزال تعمل كتاجر على شبكتها — وهي المُؤسسة التي تقوم بسك رموز WBTC وحرقها للحفاظ على نسبة 1:1 من الرموز إلى احتياطيات BTC.

على غرار شبكة Kyber، فإنّ Ren شركة تركز على الاندماج عبر السلسلة لأصول العملة المشفرة وتطبيقات التمويل اللامركزي (DeFi) عبر حلول مثل RenBridge و RenVM وغيرها. تأسست Ren في عام 2017 من قبل تاينغ تشانغ ولونج وانغ.

### ما الذي يُميز البيتكوين المُغلف (WBTC)؟

بحكم كونها أقدم وأكبر عملة مشفرة في السوق، تتباهى Bitcoin بقاعدة مستخدمين ضخمة ومُجمع سيولة يبلغ عشرات المليارات من الدولارات. ولكن وظيفة سلسلة الكتل الخاصة بها بسيطة نسبيًا وفقًا للمعايير الحديثة.

وعلى عكس Bitcoin، تم إنشاء Ethereum من الألف إلى الياء لدعم حالات الاستخدام الأكثر تقدمًا من خلال الاستفادة من تقنية العقود الذكية، مما أدى إلى ظهور مجال كامل يُسمى "التمويل اللامركزي".

تُقدم Ethereum والمنتجات المشتقة منها لمستخدميها أدوات مالية متقدمة مثل الإقراض والتأمين، والتي لا تحتاج إلى وسطاء موثوق بهم.

من خلال "تغليف" بيتكوين BTC على مُعيار ERC-20، يُتيح البيتكوين المُغلف (WBTC) الاندماج الكامل لأصل يُشبه Bitcoin في هذه البيئة المتقدمة من التطبيقات المالية اللامركزية، مما يوفر السيولة الهائلة المرتبطة بسوق BTC.

بالإضافة إلى ذلك، فإن البيتكوين المُغلف (WBTC) يجعل المهمة أسهل بكثير لعمليات التبادل والمحافظ وخدمات الدفع التي تعمل مع Ethereum: فبدلاً من الاضطرار إلى تشغيل عُقدتين منفصلتين لشبكات ETH و BTC، يمكنهم دعم عمليات WBTC باستخدام عقدة Ethereum فقط.

وأخيرًا، يزيد متوسط وقت الكتلة على سلسلة كتل Ethereum — حوالي 15 ثانية مقابل 10 دقائق على التوالي — من السرعة التي يمكن بها التعامل مع البيتكوين المُغلف (WBTC)، مقارنةً بعملة البيتكوين الفعلية.

### كم عدد عملات البيتكوين المُغلف (WBTC) المُتداولة؟

لا يوجد جدول زمني محدد مسبقًا لإصدار WBTC. بدلاً من ذلك، يتم سك أو حرق WBTC تلقائيًا عندما يقوم المستخدمون بشراء أو بيع الرموز الخاصة بهم مقابل Bitcoin عبر نظام التجار والأمناء.

نظرًا لأن البيتكوين المُغلف مدعوم دائمًا بواسطة Bitcoin بنسبة 1:1، فإن عدد الرموز المُتداولة يعتمد بشكلٍ مباشر على مقدار احتياطيات Bitcoin في شبكة WBTC. اعتبارًا من أكتوبر 2020، كان هذا الرقم يزيد قليلاً عن 94,000 رمز، بقيمة إجمالية تبلغ حوالي 1 مليار دولار.

### كيف يتم تأمين شبكة البيتكوين المُغلف (WBTC)؟

يتم تأمين رموز WBTC بواسطة سلسلة الكتل الأم التي يتم تشغيلها عليها — Ethereum. وفي المقابل، تتم حماية ETH بواسطة وظيفة تجزئة (Ethash) [إثبات العمل](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake)، وهي ممثلة لعائلة Keccak لوظائف التجزئة.

### أين يُمكنك شراء البيتكوين المُغلف (WBTC)؟

يمكنك شراء WBTC من العديد من منصات التداول، المركزية واللامركزية، والتي تعمل كتجار على شبكة بيتكوين المغلفة. بعض من أهمها:

DAI is an Ethereum-based stablecoin (stable-price cryptocurrency) whose issuance and development is managed by the Maker Protocol and the MakerDAO decentralized autonomous organization.

The price of DAI is soft-pegged to the U.S. dollar and is collateralized by a mix of other cryptocurrencies that are deposited into smart-contract vaults every time new DAI is minted.

It is important to differentiate between Multi-Collateral DAI and Single-Collateral DAI (SAI), an earlier version of the token that could only be collateralized by a single cryptocurrency; SAI also doesn’t support the DAI Savings Rate, which allows users to earn savings by holding DAI tokens.

Multi-Collateral DAI was launched in November 2019.

TUSD is the first digital asset with live on-chain attestations by independent third-party institutions and is backed 1:1 with the U.S. dollar (USD). So far, it has been listed on more than 100 trading platforms such as Binance and Huobi and is live on 12 mainstream public chains, including Ethereum, TRON, Avalanche, BSC, Fantom, and Polygon.

TrueUSD is attested to in real-time by an independent, industry-specialized accounting firm in the U.S., to ensure the 1:1 ratio of its USD reserve to the circulating token supply and the 100% collateral rate. With the integration of Chainlink PoR, TrueUSD becomes the first USD-Backed stablecoin to secure minting and further ensure transparency and reliability. Users can access the relevant data via the official website tusd.io at any time. TUSD is granted statutory status as authorized digital currency and medium of exchange in the Commonwealth of Dominica, a country in the Caribbean, effective on October 7th 2022.

Founded in September of 2018, Pax Dollar is a flat-collateralized stablecoin. Stablecoins are cryptocurrencies that are designed to minimize the volatility of the price of the stablecoin, relative to a certain stable asset or a basket of assets.

A stablecoin can be pegged to a cryptocurrency or flat money. In some cases, it can even be traded for commodities. Pax Dollar offers the advantage of transacting with blockchain assets through minimized price risk. The Pax Dollar tokens (USDP) are issued asERC-20 tokens on the Ethereum blockchain and are collateralized 1:1 through the USD held in Paxos-owned US bank accounts.

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.

USDC is a stablecoin that is pegged to the U.S. dollar on a 1:1 basis. Every unit of this cryptocurrency in circulation is backed up by $1 that is held in reserve, in a mix of cash and short-term U.S. Treasury bonds. The Centre consortium, which is behind this asset, says USDC is issued by regulated financial institutions.

The stablecoin originally launched on a limited basis in September 2018. Put simply, USDC’s mantra is “digital money for the digital age” — and the stablecoin is designed for a world where cashless transactions are becoming more common.

Several use cases have been unveiled for the USDC. As well as providing a safe haven for crypto traders in times of volatility, those behind the stablecoin say it can also allow businesses to accept payments in digital assets, and shake up an array of sectors including decentralized finance and gaming.

Overall, the goal is to create an ecosystem where USDC is accepted by as many wallets, exchanges, service providers and dApps as possible.

USDC

Bitcoin Cash (BCH) is a peer-to-peer electronic cash system that aims to become sound global money with fast payments, micro fees, privacy and larger block size. As a permissionless, decentralized cryptocurrency, Bitcoin Cash requires no trusted third parties.

Bitcoin Cash was created as an alternative to the first and most valuable cryptocurrency — Bitcoin (BTC). In 2017, BCH developers modified the BTC code, releasing their software version and a full-fledged competitive product, which split Bitcoin into two blockchains: Bitcoin and Bitcoin Cash. Bitcoin Cash is a result of a hard fork in the blockchain due to differences in the community over Bitcoin scaling and the SegWit upgrade. Moreover, another hard fork, which divided Bitcoin Cash into two parts, Bitcoin ABC and Bitcoin SV, took place in the fall of 2018.

The scaling debate involved two sides: small block supporters opposed increasing block size as it could lead to blockchain centralization and vulnerability by making it harder to host full nodes. Large block supporters, however, advocated for a faster solution, concerned that rising transaction fees could hinder growth.

Bitcoin Cash

The Gemini Trust Company (Gemini) is a digital currency exchange and custodian that allows you to buy, sell and store digital assets, founded in February of 2014. The GUSD is created by the cryptocurrency exchange Gemini.

The company received approval from the New York Department of Financial Services or NYDFS to launch the stablecoin in September of 2018. The Gemini Trust Company holds USD deposits that correspond to the number of tokens that are in circulation.

When it comes to the Gemini Dollar itself, it is an ERC-20 token that is built on the Ethereum network and has smart contracts that are audited by the security company Trail of Bits Inc.

This dollar is intended to bridge the divide between traditional finance and the crypto industry, due to the fact that this specific stablecoin is completely regulated by the NYDFS.

Bitcoin Gold was founded in 2017 to become a user-friendly alternative to Bitcoin. The BTG network aims to combine the security and sturdiness of the Bitcoin blockchain and its characteristics with the opportunity for experimentation and development.

BTG enhances and extends the crypto space with a blockchain closely compatible with Bitcoin but without using resources like Bitcoin hash power or vying for the "real Bitcoin" title. The company aims to present a coin with the implementation capabilities of Bitcoin, however, expanding on the opportunities for DeFi and DApp developers to use the coin.

USDD is a stablecoin issued by the TRON DAO Reserve. It’s pegged to the value of the US dollar and aims to provide a reliable, decentralized cryptocurrency for blockchain transactions. USDD can be used for payments, trading, staking and as a value store.

USDD is backed by a number of cryptocurrencies, including Bitcoin, Ethereum and TRON. To ensure stability and security, the reserve is over-collateralized, meaning that it holds more assets than the amount of USDD currently in circulation.

USDD

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.

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

OKB is a cryptocurrency released by the OK Blockchain Foundation and Maltese crypto exchange, OKEx. The exchange is one of the largest in the world andcurrently ranks third in liquidity, fourth in trading volume, and provides a wide selection of trading pairs. OKEx is similar in many aspects to the cryptocurrency exchange giantBinance, but there are a few key differences. The OKEx platform has its owncloud mining service, and the company has a more focused reach in providing options trading for users. Meanwhile, Binance strives to offer a broad range of crypto services globally.

OKB is the OKEx utility token that enables users to access the crypto exchange's special features. The coin is used to calculate and pay trading fees, grant users access to voting and governance on the platform, and reward users for holding OKB.

OKEx has become a world-leading trading floor since its launch in 2017. The platform launched in the spring of 2017 and emerged as an offshoot from the original OKCoin platform (operating since 2013 in China). OKCoin now focuses on exchanging fiat for crypto, while OKEx focuses on crypto trading with a built-inAPI for algorithmic trading. The exchange also gives users access to a multi-currency wallet and functions formargin trading.

Maker (MKR) is the governance token of the MakerDAO and Maker Protocol — respectively a decentralized organization and a software platform, both based on the Ethereum blockchain — that allows users to issue and manage the DAI stablecoin.

Initially conceived in 2015 and fully launched in December 2017, Maker is a project whose task is to operate DAI, a community-managed decentralized cryptocurrency with a stable value soft-pegged to the US dollar.

MKR tokens act as a kind of voting share for the organization that manages DAI; while they do not pay dividends to their holders, they do give the holders voting rights over the development of Maker Protocol and are expected to appreciate in value in accordance with the success of DAI itself.

The Maker ecosystem is one of the earliest projects on the decentralized finance (DeFi) scene: the industry that seeks to build decentralized financial products on top of smart-contract-enabled blockchains, such as Ethereum.

Yearn.finance is an aggregator service for decentralized finance (DeFi) investors, using automation to allow them to maximize profits from yield farming.

Its goal is to simplify the ever-expanding DeFi space for investors who are not technically minded or who wish to interact in a less committal manner than serious traders.

Launched in February 2020, the service, formerly known as iEarn, has seen huge growth in recent months as new products debuted and developers released in-house token YFI.

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.

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.

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.
