Answer 1

感谢您的问答。但对我来说，只有toHex返回正确的哈希：

const { sha256 } = require("@cosmjs/crypto")
const { toHex } = require("@cosmjs/encoding")
const txRaw = "<raw>"
const txHash = toHex(sha256(Buffer.from(txRaw,'base64')))
console.log(txHash)

也许它对某人有用。。。

Answer 2

我找到了答案，希望它能帮助到别人，简单的是：

const txHash=sha256(Buffer.from(txRaw，'base64'((
