Near Foundation 推出「鏈簽名」以簡化多區塊鏈交易簽名

Near 基金會的鏈簽名協議允許用戶使用其 Near 帳戶在其他區塊鏈（例如以太坊、比特幣、狗狗幣）上簽署交易。鏈簽名由 MPC 提供支援並由近端驗證器提供保護，使近端帳戶能夠控制多個區塊鏈上的地址，從而促進去中心化金融中的用例。此外，它還包括一個多鏈 Gas 中繼器，無需其他鏈上的原生 Gas 代幣，並允許使用 Near 或 NEP-141 代幣進行交易。

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

Near Foundation 推出用於多區塊鏈交易簽名的“鏈簽名”

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 基金會推出了 Chain Signatures，這是一項突破性的協議，使用戶能夠使用集中的 Near 帳戶方便地在不同的區塊鏈上簽署交易。 Near 發言人證實，Chain Signatures 目前在 Near 的測試網路上運行，預計將在 5 月初進入主網運行。

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 利用分散式多方運算 (MPC) 網絡，並由近網絡驗證器的安全性提供支援。它允許包含智能合約的近帳戶為任何區塊鏈執行交易簽名。每個近帳戶都可以無縫管理所有區塊鏈上的多個地址，從而在去中心化金融領域培育新穎的應用程式。該基金會預計 EigenLayer 將進一步增強 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."

尼爾基金會表示：“包括比特幣在內的非智能合約鏈上的去中心化金融（DeFi）現在在眾多網絡中都是可行的前景。” “開發人員可以輕鬆創建 DeFi 解決方案，利用其他鏈上的資產，而無需顯式橋接。”

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

Chain Signatures 目前支援以太坊、Cosmos 鏈、Dogecoin、比特幣和 XRP Ledger，即將支援 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.

為了進一步提高用戶便利性，Chain Signatures 配備了“多鏈 Gas 中繼器”，無需用戶擁有目標區塊鏈的原生 Gas 代幣。相反，用戶可以利用 Near 或 NEP-141 代幣在任何支援的鏈上結算交易費用。

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.

透過引入鏈簽名，Near Foundation 旨在簡化區塊鏈之間的交互，實現無縫跨鏈交易並為 DeFi 應用釋放新的可能性。
