## Wrapped Bitcoin (WBTC) คืออะไร?

[Wrapped Bitcoin](https://coinmarketcap.com/alexandria/th/article/what-is-wrapped-bitcoin) เป็น [Bitcoin](https://coinmarketcap.com/th/currencies/bitcoin/) (BTC) [ในเวอร์ชันโทเค็น](https://coinmarketcap.com/th/currencies/ethereum/) ที่ทำงานบนบล็อกเชน Ethereum (ETH)

WBTC เป็นไปตาม [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) ซึ่งเป็นมาตรฐานความเข้ากันได้ขั้นพื้นฐานของ Ethereum blockchain ที่ทำให้สามารถรวมเข้ากับระบบนิเวศของการแลกเปลี่ยนแบบกระจายอำนาจบริการ, การให้ยืม crypto, การทำนายตลาดและแอปพลิเคชัน ERC-20-enabled decentralized finance [(DeFi)](https://coinmarketcap.com/alexandria/article/what-is-decentralized-finance) อื่น ๆ ที่เปิดใช้งาน

WBTC ยังได้รับการสนับสนุนโดย Bitcoin ในอัตราส่วน 1: 1 ผ่านเครือข่ายของพ่อค้าและผู้ดูแลที่ตรวจสอบโดยอัตโนมัติ ทำให้มั่นใจได้ว่าราคาจะถูกตรึงไว้ที่ Bitcoin ตลอดเวลา และช่วยให้ผู้ใช้สามารถถ่ายโอนสภาพคล่องระหว่าง BTC และเครือข่าย ETH ในแบบกระจายอำนาจและ ลักษณะที่เป็นอิสระ

Wrapped Bitcoin ได้ออกประกาศครั้งแรกเมื่อวันที่ 26 ตุลาคม 2018 และเปิดตัวอย่างเป็นทางการในวันที่ 31 มกราคม 2019

### ใครคือผู้ก่อตั้ง Wrapped Bitcoin?

โครงการ Wrapped Tokens ซึ่ง WBTC เป็นส่วนหนึ่งไม่ได้ก่อตั้งขึ้นโดยบุคคลทั่วไป แต่เป็นโครงการร่วมกันของสามองค์กร: BitGo, Kyber Network และ [Ren](https://coinmarketcap.com/th/currencies/ren/)

BitGo ก่อตั้งในปี 2556 โดยนักวิทยาศาสตร์คอมพิวเตอร์ชาวอเมริกันและ Mike Belshe ซึ่งผู้ประกอบการจากบริษัทดูแลทรัพย์สินดิจิทัลการค้า, การซื้อขายและการบริการทางการเงิน นอกเหนือจากการเป็นหนึ่งในผู้พัฒนา WBTC แล้ว BitGo ยังทำหน้าที่เป็นผู้ดูแลสินทรัพย์ — ซึ่งเป็นหน่วยงานที่ถือโทเค็น WBTC และกุญแจที่สำคัญในการสร้างเหรียญให้มากขึ้น

Kyber Network เป็นโปรโตคอลสภาพคล่องบนบล็อกเชนที่ช่วยให้สามารถรสบรวมโทเค็นของคริปโตเคอร์เรนซีและแอปพลิเคชัน DeFi ที่แตกต่างกันได้ ก่อตั้งขึ้นในปี 2560 โดย Loi Luu, Victor Tran และ Yaron Velner และมีที่ตั้งอยู่ในสิงคโปร์ นอกจาก Ren แล้ว Kyber Network ยังช่วยสร้าง WBTC และยังคงทำหน้าที่เป็นผู้ขายในเครือข่าย — ซึ่งเป็นสถาบันที่สร้างและลดโทเค็น WBTC เพื่อรักษาอัตราส่วน 1 : 1 ของโทเค็นต่อเงินสำรอง BTC

เช่นเดียวกับ Kyber, Ren เป็นบริษัทที่มุ่งเน้นไปที่การผสมผสานระหว่างสินทรัพย์สกุลเงินดิจิทัลและแอปพลิเคชัน DeFi ผ่านทางโซลูชันเช่น RenBridge, RenVM และอื่น ๆ ก่อตั้งขึ้นในปี 2560 โดย Taiyang Zhang และ Loong Wang

#### อะไรที่ทำให้ Wrapped Bitcoin ไม่เหมือนใคร?

ด้วยการที่เป็นคริปโตเคอร์เรนซีที่เก่าแก่ที่สุดและใหญ่ที่สุดในตลาด Bitcoin ทำให้มีฐานผู้ใช้งานจำนวนมากและมีสภาพคล่องหลายสิบพันล้านดอลลาร์ อย่างไรก็ตามการทำงานของ blockchain นั้นมีพื้นฐานตามมาตรฐานสมัยใหม่

ซึ่งแตกต่างจาก Bitcoin คือ Ethereum ถูกสร้างขึ้นเพื่อรองรับการใช้งานขั้นสูง โดยใช้เทคโนโลยีของ smart contracts ที่ทำให้เกิดอุตสาหกรรมทั้งหมดที่เรียกว่า “decentralized finance”

Ethereum และอนุพันธ์ของมันเสนอเครื่องมือทางการเงินขั้นสูงให้กับผู้ใช้เช่น การให้กู้ยืมและการประกันภัยซึ่งไม่ต้องพึ่งพาคนกลางที่น่าเชื่อถือ

ด้วยการ “wrapping” BTC ในมาตรฐาน ERC-20 ทำให้ WBTC สามารถผสานรวมสินทรัพย์ที่มีลักษณะคล้าย Bitcoin เข้ากับสภาพแวดล้อมขั้นสูงของแอปพลิเคชัน financial decentralized ซึ่งจะนำมาซึ่งสภาพคล่องอันมหาศาลในตลาด BTC

นอกจากนี้ Wrapped Bitcoin ยังทำให้งานนั้นง่ายขึ้นอย่างมาก ไม่ว่าจะเป็นการแลกเปลี่ยน, วอลเลทและบริการการชำระเงินที่ทำงานร่วมกับ Ethereum: แทนที่จะต้องเรียกใช้การเชื่อมต่อสองแห่งแยกกันสำหรับเครือข่าย ETH และ BTC แต่การรองรับ WBTC ทำให้สามารถดำเนินการด้วยเครือข่าย Ethereum เพียงแห่งเดียว

สุดท้ายแล้วบล็อคไทม์เฉลี่ยที่เร็วขึ้นของ Ethereum blockchain - อยู่ที่ประมาณ 15 วินาทีเทียบกับ 10 นาทีตามลำดับ - เป็นเพิ่มความเร็วที่ WBTC สามารถทำธุรกรรมได้เมื่อเทียบกับ bitcoins จริง ๆ

#### มีเหรียญ Bitcoin (WBTC) ในการหมุนเวียนอยู่กี่เหรียญ?

ไม่มีกำหนดการล่วงหน้าสำหรับการออก WBTC แต่ WBTC จะถูกสร้างหรือลดลงโดยอัตโนมัติเมื่อใดก็ตามที่ผู้ใช้ซื้อหรือขายโทเค็นสำหรับ Bitcoin ผ่านระบบของพ่อค้าและผู้รับฝากทรัพย์สิน

เนื่องจาก Wrapped Bitcoin มักจะได้รับการสนับสนุนจาก Bitcoin ในอัตราส่วน 1: 1 จำนวนโทเค็นในการหมุนเวียนจึงขึ้นอยู่กับจำนวนเงินสำรองของ Bitcoin ในเครือข่าย WBTC โดยตรง ในเดือนตุลาคม 2020 มีจำนวนมากกว่า 94,000 โทเค็น ซึ่งมีมูลค่ารวมประมาณ 1 พันล้านดอลลาร์

### มีการรักษาความปลอดภัยเครือข่าย Wrapped Bitcoin อย่างไร

โทเค็น WBTC ได้รับการรักษาความปลอดภัยโดยบล็อกเชนหลักที่ทำงานบน - Ethereum ในทางกลับกัน ETH ก็ได้รับการปกป้องโดยฟังก์ชัน [proof-of-work](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) ของ Ethash ซึ่งเป็นตัวแทนของแฮชฟังก์ชันตระกูล Keccak

### คุณสามารถซื้อ Wrapped Bitcoin (WBTC) ได้จากที่ไหน?

คุณสามารถซื้อ WBTC ได้จากตัวกลางการแลกเปลี่ยนหลายแห่ง ทั้งแบบรวมศูนย์และแบบกระจายอำนาจซึ่งทำหน้าที่เป็นผู้ค้าในเครือข่าย Wrapped Bitcoin บางแห่งที่สำคัญ ได้แก่ :

* [Uniswap](https://coinmarketcap.com/th/exchanges/uniswap-v2/)

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

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

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

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.

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

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.

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.

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.

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

Huobi Token (HT) is the native token of the cryptocurrency exchange Huobi Global. It is a decentralized digital asset based on the Ethereum blockchain and is ERC-20 compliant. HT’s value is in part reliant upon the reputation of the Huobi crypto exchange, yet other factors also have an impact.

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

Huobi Token is a relatively young project. It first launched in January 2018, hot on the heels of the release of a native token on rival crypto exchange Binance. Having its own token allows Huobi to build a flexible marketing strategy in order to attract new users and further grow its platform.

One key function of the token is to reduce commissions for trading operations on the exchange, which are usually paid from users' wallets. Yet the token has much more to offer. Using HT, users can purchase monthly VIP-status plans to receive discounts on transaction fees. Token holders have the right to vote on exchange decisions, can receive crypto rewards for seasonal buybacks, and also get early access to special events. HT holders can, at any point, trade the token for other cryptocurrencies.

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.

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. EOS is fully decentralized 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.

Tezos is a high-performing blockchain and open-source platform for assets and applications, with a strong focus on code security, on-chain governance, and decentralization. Tezos 2.0, the upcoming step in the evolution of Tezos, aims to improve scalability (via layer 2s), composability, and to implement support to mainstream programming languages (like Javascript, Typescript, Python, and many others).

Initially built with formal verification in mind, the Tezos protocol enables builders to avoid bugs when developing smart contracts, making it particularly suited to applications that require a high degree of security and certainty.

Tezos’ LPoS (Liquid Proof-of-Stake) consensus mechanism enables any stakeholder to take part, directly or by delegation, in the consensus process, and to be rewarded for securing the network. Rather uniquely, Tezos’ on-chain governance system also enables stakeholders to create and vote on protocol upgrade proposals. This pioneering system allows the protocol to self-amend and upgrade itself without leading to a split (or fork) in the blockchain, empowering the community without slowing down innovation.

First proposed in 2014 and launched in 2018, the Tezos Mainnet has a proven track record of running uninterrupted ever since, having earned a strong reputation for technical excellence and a supportive community.

Tezos

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

Compound is a DeFi lending protocol that allows users to earn interest on their cryptocurrencies by depositing them into one of several pools supported by the platform.

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

When a user deposits tokens to a Compound pool, they receive cTokens in return. These cTokens represent the individual’s stake in the pool and can be used to redeem the underlying cryptocurrency initially deposited into the pool at any time. For example, by depositing ETH into a pool, you will receive cETH in return. Over time, the exchange rate of these cTokens to the underlying asset increases, which means you can redeem them for more of the underlying asset than you initially put in — this is how the interest is distributed.

On the flip side, borrowers can take a secured loan from any Compound pool by depositing collateral. The maximum loan-to-value (LTV) ratio varies based on the collateral asset, but currently ranges from 50 to 75%. The interest rate paid varies by borrowed asset and borrowers can face automatic liquidation if their collateral falls below a specific maintenance threshold.

Since the launch of the Compound mainnet in September 2018, the platform has skyrocketed in popularity, and recently passed more than $800 million in total locked value.
