Wrapped Bitcoin：连接比特币与以太坊生态系统的桥梁

Introduction

介绍

Wrapped Bitcoin (WBTC) is a transformative solution that seamlessly integrates Bitcoin's value and utility into the vast Ethereum ecosystem. This ingenious tokenization mechanism allows Bitcoin holders to tap into the burgeoning decentralized finance (DeFi) landscape, unlocking a world of financial opportunities.

Wrapped Bitcoin (WBTC) 是一种变革性解决方案，它将比特币的价值和实用性无缝集成到庞大的以太坊生态系统中。这种巧妙的代币化机制使比特币持有者能够进入新兴的去中心化金融（DeFi）领域，释放出一个充满金融机会的世界。

Wrapped Bitcoin: Concept and Function

包装比特币：概念和功能

Wrapped Bitcoin is essentially a Bitcoin-backed asset that exists on the Ethereum blockchain. It is a 1:1 representation of Bitcoin, fully convertible and redeemable, bridging the gap between the established Bitcoin network and the vibrant Ethereum ecosystem.

包装比特币本质上是存在于以太坊区块链上的比特币支持的资产。它是比特币的 1:1 代表，完全可兑换和赎回，弥合了已建立的比特币网络和充满活力的以太坊生态系统之间的差距。

By leveraging Ethereum's ERC-20 token standard, WBTC empowers Bitcoin holders to participate in a wide array of DeFi applications. These include liquidity provision on decentralized exchanges, swapping for other crypto assets, and collateralizing loans on protocols like Compound and Aave.

通过利用以太坊的 ERC-20 代币标准，WBTC 使比特币持有者能够参与广泛的 DeFi 应用。其中包括去中心化交易所的流动性提供、交换其他加密资产以及在Compound和Aave等协议上抵押贷款。

Mechanism of Wrapped Bitcoin

比特币打包机制

The creation of WBTC involves a collaborative process between users, merchants, and custodians. When a user initiates a request to wrap their Bitcoin, they approach a merchant who verifies their identity through Know Your Customer (KYC) and Anti-Money Laundering (AML) procedures.

WBTC 的创建涉及用户、商家和托管人之间的协作过程。当用户发起打包比特币的请求时，他们会联系商家，商家通过了解你的客户 (KYC) 和反洗钱 (AML) 程序验证其身份。

The merchant communicates with a custodian, who creates an equivalent amount of WBTC and transfers it to the merchant's Ethereum address. Subsequently, the user and the merchant engage in a swap transaction, exchanging Bitcoin for WBTC.

商家与托管人进行通信，托管人创建等量的 WBTC 并将其转移到商家的以太坊地址。随后，用户和商家进行互换交易，将比特币换成 WBTC。

Benefits and Applications of Wrapped Bitcoin

包装比特币的好处和应用

As an ERC-20 token, WBTC inherits all the advantages of its counterparts. It seamlessly integrates into DeFi applications, enabling Bitcoin holders to:

作为 ERC-20 代币，WBTC 继承了同类代币的所有优点。它无缝集成到 DeFi 应用程序中，使比特币持有者能够：

• Provide liquidity on decentralized exchanges: Enhance the liquidity of trading pairs involving WBTC and other crypto assets, earning rewards in the process.
• Swap into other assets on Ethereum: Convert WBTC into a wide range of Ethereum-based assets, gaining access to a diverse portfolio of investment opportunities.
• Collateralize loans on DeFi protocols: Utilize WBTC as collateral to secure loans on lending platforms, generating passive income while maintaining ownership of the underlying Bitcoin.

Total Value Locked (TVL) of Wrapped Bitcoin

为去中心化交易所提供流动性：增强涉及 WBTC 和其他加密资产的交易对的流动性，并在此过程中获得奖励。 兑换为以太坊上的其他资产：将 WBTC 转换为各种基于以太坊的资产，获得多样化的投资组合在 DeFi 协议上抵押贷款：利用 WBTC 作为抵押品在借贷平台上获得贷款，在保持底层比特币所有权的同时产生被动收入。 Wrapped Bitcoin 的总价值锁定 (TVL)

Since its inception, WBTC has witnessed a remarkable surge in adoption. As of May 15, 2024, the TVL of Wrapped Bitcoin has reached an impressive $9.673 billion, reflecting the growing demand for Bitcoin-backed assets within the DeFi ecosystem.

自成立以来，WBTC 的采用率出现了显着增长。截至 2024 年 5 月 15 日，Wrapped Bitcoin 的 TVL 已达到令人印象深刻的 96.73 亿美元，反映出 DeFi 生态系统内对比特币支持的资产的需求不断增长。

Address Poisoning Attack and Recovery

解决中毒攻击和恢复

On May 3, 2024, an anonymous user fell victim to an address poisoning attack, inadvertently sending 1,155 WBTC (worth $68 million at the time) to a phishing scammer.

2024 年 5 月 3 日，一名匿名用户成为地址中毒攻击的受害者，无意中向网络钓鱼诈骗者发送了 1,155 个 WBTC（当时价值 6800 万美元）。

The victim promptly reached out to the attacker, offering to return 90% of the funds and requesting they keep 10%. After a period of silence, the attacker unexpectedly returned 51 ETH and initiated contact via Telegram on May 9.

受害者立即联系攻击者，提出返还 90% 的资金，并要求他们保留 10%。经过一段时间的沉默后，攻击者出人意料地返还了 51 ETH，并于 5 月 9 日通过 Telegram 发起联系。

On May 10, the victim responded on-chain, leading to negotiations with the attacker. The outcome was a resolution where the attacker agreed to refund the stolen funds.

5 月 10 日，受害者在链上做出回应，导致与攻击者进行谈判。结果是攻击者同意退还被盗资金的解决方案。

On-chain data revealed that the victim's wallet began receiving funds at 03:00 PM (Vietnam time) on May 10. Subsequently, multiple other wallets contributed ETH to the victim, as the attacker utilized a coin mixer to obscure their identity.

链上数据显示，受害者的钱包于 5 月 10 日下午 03:00（越南时间）开始收到资金。随后，由于攻击者利用混币器掩盖了受害者的身份，多个其他钱包向受害者捐赠了 ETH。
