Near Foundation 推出“链签名”以简化多区块链交易签名

Near 基金会的链签名协议允许用户使用其 Near 账户在其他区块链（例如以太坊、比特币、狗狗币）上签署交易。链签名由 MPC 提供支持并由近端验证器提供保护，使近端账户能够控制多个区块链上的地址，从而促进去中心化金融中的用例。此外，它还包括一个多链 Gas 中继器，无需其他链上的原生 Gas 代币，并允许使用 Near 或 NEP-141 代币进行交易。

Near Foundation Unveils 'Chain Signatures' for Multi-Blockchain Transaction Signing

Near Foundation 推出用于多区块链交易签名的“链签名”

Near Foundation has introduced Chain Signatures, a groundbreaking protocol that empowers users to conveniently sign transactions across disparate blockchains using a centralized Near account. Currently operational on Near's testnet, Chain Signatures is anticipated to enter mainnet operation by early May, confirmed a Near spokesperson.

Near 基金会推出了 Chain Signatures，这是一种突破性的协议，使用户能够使用集中的 Near 账户方便地在不同的区块链上签署交易。 Near 发言人证实，Chain Signatures 目前在 Near 的测试网上运行，预计将在 5 月初进入主网运行。

Chain Signatures leverages a decentralized multi-party computation (MPC) network, bolstered by the security of Near network validators. It allows Near accounts, encompassing smart contracts, to execute transaction signing for any blockchain. Each Near account can seamlessly manage multiple addresses across all blockchains, fostering novel applications in the realm of decentralized finance. The foundation anticipates further enhancements to Chain Signatures' security courtesy of EigenLayer.

Chain Signatures 利用分散式多方计算 (MPC) 网络，并由近网络验证器的安全性提供支持。它允许包含智能合约的近账户为任何区块链执行交易签名。每个近账户都可以无缝管理所有区块链上的多个地址，从而在去中心化金融领域培育新颖的应用程序。该基金会预计 EigenLayer 将进一步增强 Chain Signatures 的安全性。

"Decentralized Finance (DeFi) on non-smart contract chains, including Bitcoin, is now a viable prospect across numerous networks," stated Near Foundation. "Developers can effortlessly create DeFi solutions that harness assets from other chains without the need for explicit bridging."

尼尔基金会表示：“包括比特币在内的非智能合约链上的去中心化金融（DeFi）现在在众多网络中都是可行的前景。” “开发人员可以轻松创建 DeFi 解决方案，利用其他链上的资产，而无需显式桥接。”

Chain Signatures currently supports Ethereum, Cosmos chains, Dogecoin, Bitcoin, and XRP Ledger, with impending support for Solana, TON Network, Polkadot, and others.

Chain Signatures 目前支持以太坊、Cosmos 链、Dogecoin、比特币和 XRP Ledger，即将支持 Solana、TON Network、Polkadot 等。

To further enhance user convenience, Chain Signatures features a "Multichain Gas Relayer," eliminating the requirement for users to possess the native gas token of the target blockchain. Instead, users can utilize Near or NEP-141 tokens to settle transaction fees on any supported chain.

为了进一步提高用户便利性，Chain Signatures 配备了“多链 Gas 中继器”，无需用户拥有目标区块链的原生 Gas 代币。相反，用户可以利用 Near 或 NEP-141 代币在任何支持的链上结算交易费用。

By introducing Chain Signatures, Near Foundation aims to streamline the interaction between blockchains, enabling seamless cross-chain transactions and unlocking new possibilities for DeFi applications.

通过引入链签名，Near Foundation 旨在简化区块链之间的交互，实现无缝跨链交易并为 DeFi 应用释放新的可能性。
