WBTC 替代品：包装比特币代币的综合指南

大多数区块链被设计为独立运行，这阻碍了 DeFi 市场的互操作性。包装代币作为解决方案出现

Most blockchains were designed to operate in isolation, which has hindered interoperability in the decentralized finance (DeFi) market. To address this issue, wrapped tokens emerged as a solution, allowing native assets from one chain to be used in the DeFi protocols on other chains.

大多数区块链被设计为独立运行，这阻碍了去中心化金融（DeFi）市场的互操作性。为了解决这个问题，包装代币作为一种解决方案出现，允许一条链上的原生资产在其他链上的 DeFi 协议中使用。

Wrapped Bitcoin (WBTC) is the biggest wrapped token by market capitalization, allowing Bitcoin (BTC) holders to deploy the digital currency in Ethereum’s (ETH) thriving DeFi ecosystem. However, WBTC also has downsides, with centralization being a key concern. This has led to the launch of WBTC alternatives that address the wrapped token’s limitations.

Wrapped Bitcoin (WBTC) 是市值最大的 WBTC 代币，允许比特币 (BTC) 持有者在以太坊 (ETH) 蓬勃发展的 DeFi 生态系统中部署数字货币。然而，WBTC 也有缺点，其中中心化是一个关键问题。这导致了 WBTC 替代品的推出，解决了包装代币的局限性。

Here’s a list of the leading WBTC alternatives and how they compare to WBTC.

以下列出了主要的 WBTC 替代品以及它们与 WBTC 的比较。

What Is Wrapped Bitcoin (WBTC)?

什么是包装比特币（WBTC）？

Wrapped Bitcoin (WBTC) is an ERC-20 token backed 1:1 by Bitcoin. It was launched to allow decentralized apps (dApps) on Ethereum to access Bitcoin. Thanks to this integration, developers can easily write smart contracts incorporating Bitcoin transfers.

Wrapped Bitcoin (WBTC) 是一种由比特币 1:1 支持的 ERC-20 代币。它的推出是为了允许以太坊上的去中心化应用程序（dApp）访问比特币。由于这种集成，开发人员可以轻松编写包含比特币转账的智能合约。

The token adds Bitcoin liquidity to the Ethereum ecosystem, allowing BTC holders to interact with the DeFi on Ethereum while benefiting from many of Bitcoin’s core features.

该代币为以太坊生态系统增加了比特币的流动性，使 BTC 持有者能够与以太坊上的 DeFi 互动，同时受益于比特币的许多核心功能。

To convert your BTC to wBTC, you must first send it to a custodian or merchant who’ll oversee the minting and burning process. The custodian reserves the BTC and mints an equivalent amount of WBTC before sending the tokens to your wallet on the new chain.

要将您的 BTC 转换为 wBTC，您必须首先将其发送给托管人或商人，他们将监督铸造和销毁过程。托管人会保留 BTC 并铸造等量的 WBTC，然后再将代币发送到新链上的钱包。

WBTC started on Ethereum but now is an option on several other blockchains and Ethereum Layer 2s, bringing Bitcoin liquidity to DeFi ecosystems across the cryptoverse.

WBTC 始于以太坊，但现在是其他几个区块链和以太坊第 2 层的一个选项，为整个加密世界的 DeFi 生态系统带来了比特币流动性。

WBTC Alternatives You Should Know

您应该了解的 WBTC 替代品

WBTC helped bridge the world’s largest blockchains, Bitcoin and Ethereum, and turned Bitcoin into a popular asset in the DeFi market. The wrapped token also paved the way for other tokens backed 1:1 by BTC, all of which are bringing BTC into their ecosystem to expand the use cases for the digital currency.

WBTC 帮助连接了全球最大的区块链比特币和以太坊，并将比特币变成了 DeFi 市场上的热门资产。包装代币还为其他由 BTC 1:1 支持的代币铺平了道路，所有这些代币都将 BTC 引入其生态系统，以扩展数字货币的用例。

tBTC

比特币

tBTC or Threshold Bitcoin is a permissionless BTC-pegged token launched by Threshold Network in 2020 as a wrapped form of BTC operating on Ethereum.

tBTC 或 Threshold 比特币是 Threshold Network 于 2020 年推出的一种无需许可的 BTC 挂钩代币，作为在以太坊上运行的 BTC 的包装形式。

Unlike WBTC, which relies on custodians, tBTC uses a group of nodes called signers to manage BTC deposits. Signers are selected randomly from a pool of candidates and are rotated weekly. Each signing group contains three nodes, who must first overcollateralize the incoming BTC by 150% of the value in ETH.

与依赖托管人的 WBTC 不同，tBTC 使用一组称为签名者的节点来管理 BTC 存款。签名者是从候选人库中随机选出的，并且每周轮换一次。每个签名组包含三个节点，这些节点必须首先超额抵押传入的 BTC，金额为 ETH 价值的 150%。

Signers then generate a Bitcoin wallet to which users can send their BTC. Users receive proof of their deposit, which they can send to the Ethereum network to receive the tBTC deposit token (TDT) that allows them to mint tBTC. However, the minting party must deposit a small ETH bond to guarantee they won’t default on the transaction at any point. If found at fault, the protocol forfeits the bond.

然后签名者生成一个比特币钱包，用户可以将他们的比特币发送到其中。用户收到存款证明，他们可以将其发送到以太坊网络以接收 tBTC 存款代币 (TDT)，从而允许他们铸造 tBTC。然而，铸币方必须存入少量 ETH 债券，以保证他们在任何时候都不会违约。如果发现错误，协议将丧失保证金。

To redeem tBTC back into BTC, users must undergo a multi-step verification where the Signers release the locked BTC from the smart contract into the user’s wallet, as the tBTC token is burned.

要将 tBTC 兑换回 BTC，用户必须经过多步验证，签名者将智能合约中锁定的 BTC 释放到用户的钱包中，同时 tBTC 代币将被销毁。

tBTC achieves decentralization through the signers groups and the Threshold Council. Anyone who stakes 40,000 or more T tokens is eligible to become a tBTC signer. At the same time, the Threshold Council may allow anyone with the ability to run a node to join in and boost system performance.

tBTC 通过签名者团体和阈值委员会实现去中心化。任何质押 40,000 或更多 T 代币的人都有资格成为 tBTC 签名者。同时，阈值委员会可以允许任何有能力运行节点的人加入并提高系统性能。

tBTC has maintained its peg to bitcoin since launching in 2020, thanks to its unique approach that utilizes the supply of BTC to consistently uphold stability. The token currently has a total value locked (TVL) of $193.51 million.

自 2020 年推出以来，tBTC 一直保持与比特币挂钩，这要归功于其利用 BTC 供应来持续保持稳定性的独特方法。该代币目前的总锁定价值（TVL）为 1.9351 亿美元。

renBTC

任比特币

renBTC, which stands for renewed Bitcoin, is another ERC-20 token pegged 1:1 to Bitcoin and built on Ren Virtual Machine (RenVM).

renBTC 代表更新的比特币，是另一种与比特币 1:1 挂钩的 ERC-20 代币，构建在 Ren 虚拟机 (RenVM) 上。

Also launched in 2020, RenBTC uses the lock and mint mechanism, which creates an HTLC transaction on the Bitcoin network and a smart contract on Ethereum. HTLC, a method for routing payments through multiple channels, helps execute a balance blocking operation on Bitcoin. On the other hand, the smart contract created facilitates minting of RenBTC on Ethereum.

同样于 2020 年推出的 RenBTC 使用锁定和铸币机制，在比特币网络上创建 HTLC 交易，在以太坊上创建智能合约。 HTLC 是一种通过多个渠道路由支付的方法，有助于对比特币执行余额冻结操作。另一方面，创建的智能合约有助于在以太坊上铸造 RenBTC。

All of this is possible in a decentralized environment, thanks to RenVM, which facilitates blockchain interoperability and allows for trustless cross-asset transfers. The protocol uses a decentralized network of validators, known as DarkNodes, to ensure security and achieve decentralization during the minting process.

所有这一切都可以在去中心化环境中实现，这要归功于 RenVM，它促进了区块链互操作性并允许无需信任的跨资产转移。该协议使用去中心化的验证器网络（称为 DarkNodes）来确保铸造过程中的安全性并实现去中心化。

By implementing the Proof of Stake (PoS) consensus model, anyone can become a network validator for RenBTC. To become eligible, you must first lock up 100,000 REN (the network’s native token) with the protocol. However, the 100K cap poses a centralization risk on the network, as there

通过实施权益证明（PoS）共识模型，任何人都可以成为 RenBTC 的网络验证者。要获得资格，您必须首先使用协议锁定 100,000 REN（网络的原生代币）。然而，100K 上限给网络带来了中心化风险，因为
