NEAR 协议解锁跨链交易并增强与链签名的互操作性

NEAR Protocol 联合创始人兼 NEAR 基金会首席执行官 Illia Polosukhin 在韩国首尔的 BUIDL Asia 上公布了链签名。此功能使 NEAR 账户和智能合约能够为任何区块链签署交易。利用由 NEAR 协议质押和 Eigenlayer ETH 重试者保护的去中心化 MPC 网络，链签名支持多个区块链，并引入由 NEAR 账户控制的门限签名机制。

NEAR Protocol Unveils Chain Signatures for Cross-Chain Transactions and Enhanced Interoperability

NEAR 协议推出跨链交易链签名和增强的互操作性

Seoul, South Korea – NEAR Protocol Co-Founder and NEAR Foundation CEO Illia Polosukhin unveiled Chain Signatures at the BUIDL Asia event in Seoul, a groundbreaking feature that empowers NEAR accounts, including smart contracts, to sign transactions for any blockchain.

韩国首尔 – NEAR Protocol 联合创始人兼 NEAR 基金会首席执行官 Illia Polosukhin 在首尔举行的 BUIDL Asia 活动上推出了 Chain Signatures，这是一项突破性功能，使 NEAR 账户（包括智能合约）能够为任何区块链签署交易。

Cross-Chain Transactions: Breaking Down Blockchain Boundaries

跨链交易：打破区块链边界

Chain Signatures utilize a decentralized Multi-Party Computation (MPC) network, leveraging NEAR Protocol staking and Eigenlayer ETH restakers for robust security. Supported chains include Bitcoin, Ethereum, Cosmos, Dogecoin, and XRP Ledger, with plans for Solana, TON Network, Polkadot, and others to join the roster.

Chain Signatures 利用去中心化的多方计算 (MPC) 网络，利用 NEAR 协议质押和 Eigenlayer ETH 重试者来实现强大的安全性。支持的链包括比特币、以太坊、Cosmos、Dogecoin 和 XRP Ledger，并计划让 Solana、TON Network、Polkadot 等加入。

The mechanism works through threshold signatures controlled by NEAR accounts and smart contracts. NEAR validators or MPC nodes can sign arbitrary payloads, such as transactions for other blockchains, upon request from a NEAR account. This account-based MPC network streamlines cross-chain interoperability without the burden of managing multiple addresses on various chains.

该机制通过 NEAR 账户和智能合约控制的门限签名发挥作用。 NEAR 验证器或 MPC 节点可以根据 NEAR 账户的请求签署任意有效负载，例如其他区块链的交易。这种基于账户的 MPC 网络简化了跨链互操作性，无需管理各个链上的多个地址。

Multichain Gas Relayer: Simplifying DeFi Transactions

多链 Gas Relayer：简化 DeFi 交易

Chain Signatures and the Multichain Gas Relayer enhance DeFi adoption by simplifying cross-chain interoperability. This unlocks diverse use cases for mainstream users and Web3 developers. For instance, users can collateralize XRP to borrow USDC or trade DOGE for SOL. By serving all ecosystems from a single interface, Chain Signatures eliminate the need for developers to commit to a specific chain or liquidity pool.

链签名和多链 Gas Relayer 通过简化跨链互操作性来增强 DeFi 的采用。这为主流用户和 Web3 开发人员解锁了不同的用例。例如，用户可以抵押 XRP 借入 USDC 或用 DOGE 换取 SOL。通过从单一界面为所有生态系统提供服务，链签名消除了开发人员承诺特定链或流动性池的需要。

Eigenlayer Partnership and Permissionless Network

Eigenlayer 合作伙伴关系和无需许可的网络

Eigenlayer partners with Chain Signatures to secure the MPC network, with plans for a permissionless network of node operators based on staking requirements. The launch also introduces the Multichain Gas Relayer, enabling users to cover gas fees on any chain using NEAR Protocol or NEP-141 tokens.

Eigenlayer 与 Chain Signatures 合作保护 MPC 网络，并计划根据质押要求建立无需许可的节点运营商网络。此次发布还推出了多链 Gas Relayer，使用户能够使用 NEAR 协议或 NEP-141 代币支付任何链上的 Gas 费用。

Web3 Design Patterns and Multichain Account Abstraction

Web3 设计模式和多链账户抽象

Chain Signatures introduce new Web3 design patterns, allowing smart contracts on NEAR to custody assets on any chain. This facilitates bridgeless cross-chain DeFi applications, such as RFQs, order books, AMMs, and lending protocols. Additionally, Multichain Account Abstraction enables a single NEAR account to manage accounts on various chains, simplifying user experiences and expanding addressable markets for developers.

Chain Signatures引入了新的Web3设计模式，允许NEAR上的智能合约托管任何链上的资产。这有利于无桥跨链 DeFi 应用，例如询价、订单簿、AMM 和借贷协议。此外，多链账户抽象使单个 NEAR 账户能够管理不同链上的账户，从而简化用户体验并扩大开发者的潜在市场。

NEAR's Commitment to Web3 Accessibility

NEAR 对 Web3 可访问性的承诺

"NEAR Protocol is committed to simplifying Web3 access for developers and users," said Polosukhin. "Chain Signatures mark a significant step towards defragmenting liquidity across the ecosystem, enabling decentralized apps to deliver more powerful experiences and address the entire Web3 market."

“NEAR 协议致力于简化开发人员和用户的 Web3 访问，”Polosukhin 说。 “链签名标志着整个生态系统中流动性碎片整理的重要一步，使去中心化应用程序能够提供更强大的体验并满足整个 Web3 市场的需求。”

Several projects within the NEAR ecosystem are already leveraging Chain Signatures to introduce innovative design patterns and experiences. With Chain Signatures, Web3 developers can explore new use cases and expand the landscape of multichain apps and experiences.

NEAR 生态系统中的多个项目已经在利用链签名来引入创新的设计模式和体验。借助 Chain Signatures，Web3 开发人员可以探索新的用例并扩展多链应用程序和体验的前景。
