Mina Client Javascript SDK 允许生成密钥对、签名和验证消息，以及可以将签名交易在网络上进行广播。 该项目包含 Typescript 和 ReasonML 的类型，但也可以从普通的 NodeJS 中使用。有以下几种方法： genKeys - 生成公钥/私钥对。 derivePublicKey - 导出对应私钥的公钥。 signMessage - 对任意消息进行签名。 verifyMessage - 验证签名是否与消息匹配。 signPayment - 使用私钥对支付进行签名。 signstakes delegation - 使用私钥对权益委托进行签名 请注意 客户端 SDK 允许在从不向网络公开私钥的设备上生成和进行交易签名。 安装 yarn add @o1labs/client-sdkor with npm:npm install --save @o1labs/client-sdk 使用 Typescript import * as MinaSDK from "@o1labs/client-sdk"; let keys = MinaSDK.genKeys(); let signed = MinaSDK.signMessage("hello", keys); if (MinaSDK.verifyMessage(signed)) { console.log("Message was verified successfully") }; let signedPayment = MinaSDK.signPayment({ to: keys.publicKey, from: keys.publicKey, amount: 1, fee: 1, nonce: 0 }, keys); NodeJS const MinaSDK = require("@o1labs/client-sdk"); let keys = MinaSDK.genKeys(); let signed = MinaSDK.signMessage("hello", keys); if (MinaSDK.verifyMessage(signed)) { console.log("Message was verified successfully") }; let signedPayment = MinaSDK.signPayment({ to: keys.publicKey, from: keys.publicKey, amount: 1, fee: 1, nonce: 0 }, keys); ReasonML 安装 gentype：yarn add -D gentype 安装 bs-platform：yarn add -D bs-platform 编译依赖：yarn bsb -make-world module MinaSDK = O1labsClientSdk.CodaSDK; let keys = MinaSDK.genKeys(); let signed = MinaSDK.signMessage(. "hello", keys); if (MinaSDK.verifyMessage(. signed)) { Js.log("Message was verified successfully"); }; let signedPayment = MinaSDK.signPayment({ to_: keys.publicKey, from: keys.publicKey, amount: "1", fee: "1", nonce: "0" }, keys); 请注意 当产生交易时，您需要指定帐户。您可以通过 CLI 使用 mina advanced get-nonce -address 或使用 GraphQL 来获得这个账户。
