链签名主网发布将链抽象带入生活

今天标志着 Chain Signatures 的正式主网发布，Chain Signatures 是一个基于 NEAR 构建的突破性链抽象解决方案。

Chain Signatures, a groundbreaking Chain Abstraction solution built on NEAR Protocol, has officially launched on Mainnet. After a successful testnet phase and security audit, Chain Signatures is now fully available for developers to integrate into their dApps on Mainnet, enabling omnichain capabilities.

Chain Signatures 是一个基于 NEAR 协议的突破性链抽象解决方案，已在主网上正式启动。经过成功的测试网阶段和安全审核后，开发人员现在完全可以将 Chain Signatures 集成到主网上的 dApp 中，从而实现全链功能。

Degens and end users can now enjoy a fully chain abstracted user experience on the first cohort of Chain Signatures products already live on mainnet.

Degens 和最终用户现在可以在主网上已经上线的第一批 Chain Signatures 产品上享受完全链抽象的用户体验。

Chain Signatures utilizes a decentralized multi-party computation (MPC) network enabling NEAR accounts to sign transactions on any blockchain protocol. Chain Signatures is the only MPC solution where smart contracts can sign transactions on any chain and for any number of accounts. This is possible because accounts are smart contracts by default in the unique NEAR account model.

Chain Signatures 利用去中心化多方计算 (MPC) 网络，使 NEAR 帐户能够在任何区块链协议上签署交易。 Chain Signatures 是唯一一个 MPC 解决方案，智能合约可以在任何链上为任意数量的账户签署交易。这是可能的，因为在独特的 NEAR 账户模型中账户默认是智能合约。

Chain Signatures reduces the work of multichain dApp development to a single layer: a smart contract on NEAR that can talk to all other chains. In this way, Chain Signatures abstracts away the complexity and hassle of multichain dApps, for both developers and users alike, and opens up an entirely new design space of applications and user interfaces for Web3. Additionally, while existing bridges or cross-chain messaging protocols cannot support all chains or scale at speed, Chain Signatures can support every blockchain without native integration, whether Ethereum, Bitcoin, the Cosmos ecosystem, or (soon) Solana.

Chain Signatures 将多链 dApp 开发工作减少到单层：NEAR 上的智能合约可以与所有其他链通信。通过这种方式，Chain Signatures 为开发人员和用户消除了多链 dApp 的复杂性和麻烦，并为 Web3 开辟了一个全新的应用程序和用户界面设计空间。此外，虽然现有的桥或跨链消息传递协议无法支持所有链或快速扩展，但链签名可以支持每个区块链而无需本地集成，无论是以太坊、比特币、Cosmos 生态系统还是（即将推出的）Solana。

Five applications with more than 6 million active users between them are already using Chain Signatures Mainnet as of launch, with more than fifteen projects actively building. Soon there will be a full ecosystem of Chain Signatures products across this new design space, ranging across wallets, DEXs, lending, trading bots, bridges, and more.

截至发布时，五个活跃用户超过 600 万的应用程序已经在使用 Chain Signatures 主网，并且有超过 15 个项目正在积极建设。很快，这个新的设计空间将出现一个完整的 Chain Signatures 产品生态系统，涵盖钱包、DEX、贷款、交易机器人、桥梁等。

“Chain Signatures is pivotal to replacing the fragmented Web3 landscape with a single user and developer layer that addresses current interoperability challenges,” said Kendall Cole of Proximity Labs, a contributor to Chain Signatures. “This innovation simplifies the user experience, enables DeFi for blockchains like Bitcoin that do not traditionally support smart contracts, and empowers developers to support all chains seamlessly. By eliminating the need for bridges, Chain Signatures can significantly expand the liquidity and utility of assets across various blockchains. We’re excited to see Chain Abstraction in the wild, transforming how users and developers interact with decentralized finance and making it more accessible.”

Chain Signatures 的贡献者、Proximity Labs 的 Kendall Cole 表示：“Chain Signatures 对于用单一用户和开发人员层取代分散的 Web3 格局至关重要，该层可以解决当前的互操作性挑战。” “这项创新简化了用户体验，使传统上不支持智能合约的比特币等区块链能够实现 DeFi，并使开发人员能够无缝支持所有链。通过消除对桥梁的需求，链签名可以显着扩展各个区块链上资产的流动性和效用。我们很高兴看到 Chain Abstraction 投入使用，它改变了用户和开发人员与去中心化金融的交互方式，并使其更易于使用。”

Another key layer of the Chain Signatures stack is the Multichain Gas Relayer. Instead of forcing users to acquire a separate gas token every time they transact on a new chain, the Multichain Gas Relayer performs the gas payment on the destination chain, on the user’s behalf. The user only needs to pay the equivalent amount in an asset they already hold, whether that’s NEAR or other NEAR-native fungible tokens (such as USDC or USDT). The power of Chain Signatures, together with the gas abstraction of the Multichain Gas Relayer, offers a streamlined user experience as exemplified by top dApps like Sweat Wallet.

链签名堆栈的另一个关键层是多链气体中继器。多链 Gas Relayer 不会强迫用户每次在新链上进行交易时获取单独的 Gas 代币，而是代表用户在目标链上执行 Gas 支付。用户只需要支付他们已经持有的资产的等值金额，无论是 NEAR 还是其他 NEAR 原生可替代代币（例如 USDC 或 USDT）。链签名的强大功能与多链 Gas Relayer 的 Gas 抽象相结合，提供了简化的用户体验，Sweat Wallet 等顶级 dApp 就是例证。

“Chain Signatures is a game-changing innovation that brings Chain Abstraction to life,” added Illia Polosukhin, Co-Founder of Near Protocol and CEO of NEAR Foundation. “Whereas before we had fragmented liquidity in DeFi, now there will be a single DeFi layer for all chains. There is no more need for dozens of wallets and addresses, manual bridging, and paying gas fees in every token. Instead, all of DeFi is accessible from wherever users already are. It’s all possible because smart contracts can now sign transactions for any blockchain, even Bitcoin. This opens up a whole new design space for financial apps in Web3, benefitting degens and also paving the way for new user bases.”

“Chain Signatures 是一项改变游戏规则的创新，它将 Chain Abstraction 变为现实，”Near Protocol 联合创始人兼 NEAR 基金会首席执行官 Illia Polosukhin 补充道。 “之前我们的 DeFi 流动性分散，但现在所有链都将有一个 DeFi 层。不再需要数十个钱包和地址、手动桥接以及为每个代币支付汽油费。相反，无论用户身在何处，都可以访问所有 DeFi。这一切都是可能的，因为智能合约现在可以为任何区块链（甚至比特币）签署交易。这为 Web3 中的金融应用程序开辟了全新的设计空间，使 degens 受益，并为新的用户群铺平了道路。”

Chain Signatures’ MPC network is secured by eight reputable validators as of mainnet launch: Pagoda, Luganodes, The Lifted Initiative, InfStones, Staking4All, Node.Monster, Black Sand Technologies, and Aurora. The initial audit for the Chain Signatures protocol has been conducted by Kudelski, the final report of which will be published soon on the Chain Signatures GitHub.

自主网启动以来，Chain Signatures 的 MPC 网络由八个信誉良好的验证器提供保护：Pagoda、Luganodes、The Lifted Initiative、InfStones、Stake4All、Node.Monster、Black Sand Technologies 和 Aurora。 Kudelski 对 Chain Signatures 协议进行了初步审核，最终报告将很快发布在 Chain Signatures GitHub 上。

The Chain Signatures development roadmap includes adding EDDSA support before the end of the year, increasing throughput, and increasing the number of nodes. As of mainnet launch, Chain Signatures supports all blockchain protocols based on the ECDSA elliptic curve, which includes most chains such as Ethereum, Bitcoin, Dogecoin, and recently, NEAR. With the additional support for the EDDSA elliptic curve (e.g. Solana, TON), Chain Signatures will be able to sign transactions on every known blockchain by Q4 2024. By the end of the year, Chain Signatures will aim to increase throughput up to 300 transactions/second to match NEAR’s sharded capacity. Finally, the number of validators on the network will gradually increase over time with the aim of achieving 40+ highly independent nodes, which would require 27 for a single signature.

Chain Signatures 开发路线图包括在年底前添加 EDDSA 支持、提高吞吐量和增加节点数量。自主网启动以来，Chain Signatures 支持所有基于 ECDSA 椭圆曲线的区块链协议，其中包括大多数链，例如以太坊、比特币、狗狗币以及最近的 NEAR。通过对 EDDSA 椭圆曲线（例如 Solana、TON）的额外支持，到 2024 年第四季度，Chain Signatures 将能够在每个已知区块链上签署交易。到今年年底，Chain Signatures 的目标是将吞吐量提高至 300 笔交易/秒以匹配 NEAR 的分片容量。最后，网络上的验证器数量将随着时间的推移逐渐增加，目标是实现 40 个以上高度独立的节点，这将需要 27 个单个签名。
