Bitcoin's 10 Biggest Moments in 2020

## Wrapped Bitcoin (WBTC) کیا ہے؟

Wrapped Bitcoin [Bitcoin](https://coinmarketcap.com/ur/currencies/bitcoin/) (BTC) کا ایک ٹوکنائزڈ ورژن ہے جو [Ethereum](https://coinmarketcap.com/ur/currencies/ethereum/) (ETH) بلاک چین پر کام کرتا ہے۔

WBTC [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) کے ساتھ مطابقت پذیر ہے — جو Ethereum بلاک چین کی مطابقت پذیری کا بنیادی معیار ہے — اسے غیر مرکزی ایکسچینجز، کرپٹو قرض دینے کی سروسز، پیشین گوئی کی مارکیٹس اور دیگر ERC-20- فعال غیر مرکزی فنانس ([DeFi](https://coinmarketcap.com/alexandria/article/what-is-decentralized-finance)) ایپلیکیشنز پر مشتمل ایکو سسٹم میں مکمل طور پر شامل کیا جا سکتا ہے۔

WBTC خودکار نگرانی کے حامل ٹریڈرز اور سرپرستوں کے نیٹ ورک کے ذریعے Bitcoin کے ساتھ 1:1 کے تناسب سے تقویت یافتہ ہے، جو اس بات کو یقینی بناتا ہے کہ اس کی قیمت ہر وقت Bitcoin کے ساتھ پیگ شدہ ہے اور صارفین کو BTC اور ETH نیٹ ورکس کے درمیان غیر مرکزی اور خودکار طریقے سے لیکویڈیٹی ٹرانسفر کرنے کی اجازت دیتا ہے۔

26 اکتوبر 2018 کو Wrapped Bitcoin کا پہلی بار اعلان کیا گیا تھا، اور اس کا باضابطہ آغاز 31 جنوری 2019 کو ہوا۔

### Wrapped Bitcoin کے بانیان کون ہیں؟

Wrapped Tokens پراجیکٹ، جس کا ایک حصہ WBTC بھی ہے، کی بنیاد افراد نے نہیں رکھی تھی، بلکہ یہ تین تنظیموں کا مشترکہ پراجیکٹ ہے: BitGo، Kyber Network اور [Ren](https://coinmarketcap.com/ur/currencies/ren/)۔

BitGo، جو 2013 میں امریکی کمپیوٹر سائنسدان اور کاروباری شخصیت Mike Belshe کی شراکت سے قائم ہوئی تھی، ادارہ جاتی ڈیجیٹل اثاثوں پر مبنی فرم ہے، جو تحویلی، ٹریڈنگ اور مالیاتی سروسز فراہم کرتی ہے۔ BitGo گوکہ WBTC کے ڈویلپرز میں سے ایک ہے، تاہم یہ اس کے اصل سرپرست کی ذمہ داری بھی ادا کر رہی ہے — یعنی یہ وہ ادارہ ہے جو WBTC ٹوکنز اور انہیں مزید منٹ کرنے کے لیے درکار کییز کو ہولڈ کرتا ہے۔

Kyber نیٹ ورک ایک آن بلاک چین لیکویڈیٹی پروٹوکول ہے جو مختلف کرپٹو کرنسی ٹوکنز اور DeFi ایپلی کیشنز کے انضمام کاری کی صلاحیت فراہم کرتا ہے۔ اس کی بنیاد 2017 میں Loi Luu، Victor Tran اور Yaron Velner نے رکھی تھی اور یہ سنگاپور میں واقع ہے۔ Ren کے علاوہ، Kyber نیٹ ورک نے WBTC بنانے میں بھی مدد فراہم کی ہے اور وہ اب بھی اس کے نیٹ ورک پر ایک مرچنٹ کے طور پر کام کرتا ہے — یعنی یہ وہ ادارہ ہے جو ٹوکنز کو BTC ریزروز کے ساتھ 1:1 تناسب سے برقرار رکھنے کے لیے WBTC ٹوکنز کو منٹ اور ضائع کرتا ہے۔

Kyber کی طرح، Ren بھی ایک ایسی کمپنی ہے جو کرپٹو کرنسی کے اثاثوں اور DeFi ایپلی کیشنز کے کراس بلاک چین انضمام پر توجہ مرکوز کرتی ہے اور اس ضمن میں RenBridge، RenVM اور دیگر ان جیسے حل بروئے کار لاتی ہے۔ 2017 میں Taiyang Zhang اور Loong Wang نے اس کی بنیاد رکھی تھی۔

### وہ کیا چیز ہے جو Wrapped Bitcoin کو منفرد بناتی ہے؟

مارکیٹ میں سب سے قدیم اور سب سے بڑی کرپٹو کرنسی ہونے کی بدولت، Bitcoin کو ایک بڑے صارفی بیس اور کئی درجن بلین ڈالر مالیت کے لیکویڈیٹی پول کا اعزاز حاصل ہے۔ تاہم، جدید معیارات کے لحاظ سے اس کی بلاک چین کی فعالیت نسبتاً بنیادی ہے۔

Bitcoin کے برعکس، Ethereum کو بنیادی طور پر اسمارٹ معاہدوں کی ٹیکنالوجی بروئے کار لاتے ہوئے استعمال کی زیادہ جدید صورتوں کی معاونت کے لیے بنایا گیا تھا، جس نے ایک مکمل انڈسٹری کو وجود دیا جسے "غیر مرکزی فنانس" کا نام دیا گیا ہے۔

Ethereum اور اس سے ماخوذ پراڈکٹس اپنے صارفین کو قرض دینے اور انشورنس کی طرح ایسے جدید مالیاتی آلات پیش کرتے ہیں، جس کے لیے اعتماد یافتہ درمیانی فریقین پر انحصار کرنے کی ضرورت نہیں ہوتی۔

ERC-20 اسٹینڈرڈ میں BTC کی "ریپنگ" کرنے سے، WBTC مالیاتی غیر مرکزی ایپلی کیشنز کے اس جدید ماحول میں Bitcoin جیسے اثاثے کے مکمل انضمام کو فعال کرتا ہے، جس کے نتیجے میں BTC کی مارکیٹ سے وابستہ بے پناہ لیکویڈیٹی بھی ساتھ میں آتی ہے۔

اس کے علاوہ، Wrapped Bitcoin ایسے ایکسچینجز، والیٹس اور ادائیگی کی سروسز کے لیے کام کرنا مزید آسان بنا دیتا ہے جو Ethereum کے ساتھ کام کرتی ہیں: ETH اور BTC نیٹ ورکس کے لیے دو الگ الگ نوڈز چلانے کے بجائے، وہ صرف ایک Ethereum نوڈ کے ذریعے WBTC آپریشنز کی معاونت کر سکتی ہیں۔

حتمی طور پر، Ethereum بلاک چین کا تیز اوسط بلاک ٹائم bitcoins کے مقابلے میں — بالترتیب تقریباً 15 سیکنڈ بمقابلہ 10 منٹ ہوتا ہے — یہ اس رفتار کو بڑھاتا ہے جس پر WBTC کو ٹرانزیکٹ کیا جا سکتا ہے۔

CMC Alexandria پر Wrapped Bitcoin کے بارے میں بنیادی معلومات [یہاں](https://coinmarketcap.com/alexandria/article/what-is-wrapped-bitcoin) سے دیکھی جا سکتی ہیں۔

### کُل کتنے Wrapped Bitcoin (WBTC) کوائنز گردش میں ہیں؟

WBTC کے اجراء کا کوئی پہلے سے طے شدہ شیڈول نہیں ہے۔ اس کے بجائے، جب بھی صارفین مرچنٹسس اور سرپرستوں کے ایک سسٹم کے ذریعے Bitcoin کے لیے اپنے ٹوکن خریدتے یا بیچتے ہیں تو WBTC کو خودکار طور پر منٹ یا ضائع کر دیا جاتا ہے۔

چونکہ Wrapped Bitcoin ہمیشہ 1:1 کے تناسب سے Bitcoin کے ساتھ تقویت یافتہ ہے، اس لیے گردش میں موجود ٹوکنز کی تعداد براہ راست WBTC نیٹ ورک میں Bitcoin ریزروز کی مقدار پر منحصر ہے۔ اکتوبر 2020 تک، یہ تعداد محض 94,000 ٹوکنز سے زیادہ تھی، جس کی کل مالیت تقریباً $1 بلین تھی۔

### Wrapped Bitcoin نیٹ ورک کو کس طرح سے محفوظ بنایا جاتا ہے؟

WBTC ٹوکنز اصل بلاک چین کے ذریعے محفوظ کیے جاتے ہیں جس پر وہ چلتے ہیں — یعنی Ethereum۔ جس کے بدلے میں، ETH کو Ethash پروف-آف-ورک فنکشن کے ذریعے محفوظ کیا جاتا ہے، جس کا تعلق ہیش فنکشنز کی Keccak فیملی سے ہے۔

### آپ Wrapped Bitcoin (WBTC) کو کہاں سے خرید سکتے ہیں؟

آپ WBTC کو متعدد ایکسچینجز پر خرید سکتے ہیں، جن میں مرکزی اور غیر مرکزی دونوں شامل ہیں، جو کہ Wrapped Bitcoin کے نیٹ ورک پر مرچنٹس کی حیثیت سے کام کرتے ہیں۔ ان میں سے کچھ اہم درج ذیل ہیں:

* [Uniswap](https://coinmarketcap.com/ur/exchanges/uniswap-v2/)
* [Binance](https://coinmarketcap.com/ur/exchanges/binance/)
* [OKEx](https://coinmarketcap.com/ur/exchanges/okex/)
* [Huobi Global](https://coinmarketcap.com/ur/exchanges/huobi-global/)

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.

TrueUSD

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.

Pax Dollar

Binance USD (BUSD) is a 1:1 USD-backed stable coin issued by Binance (in partnership with Paxos), Approved and regulated by the New York State Department of Financial Services (NYDFS), The BUSD Monthly Audit Report can be viewed from the official website. Launched on 5 Sep 2019, BUSD aims to meld the stability of the dollar with blockchain technology. It is a digital fiat currency, issued as ERC-20 and supports BEP-2.

BUSD

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

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

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 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.

Bitcoin Gold

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

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

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.

Maker

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.

Zcash

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.

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.

Gemini Dollar

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.

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

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.
