PoW Ethash CPU 矿工

里面有一个简单的CPU矿工 Ethash 用于测试目的的软件包.

参见下例如何使用新的 Miner 类 :

// ./examples/miner.ts

import { createBlock } from '@ethereumjs/block'
import { Ethash } from '@ethereumjs/ethash'
import { MapDB, bytesToHex } from '@ethereumjs/util'

import type { DBObject } from '@ethereumjs/util'

const block = createBlock(
  {
    header: {
      difficulty: BigInt(100),
      number: BigInt(1),
    },
  },
  { setHardfork: true, skipConsensusFormatValidation: true },
)

const cacheDB = new MapDB<number, DBObject>()

const e = new Ethash(cacheDB)
const miner = e.getMiner(block.header)
const solution = await miner.iterate(-1) // iterate until solution is found
console.log(bytesToHex(solution!.mixHash)) // 0x892177e7bbb1f31ade0610707c96c6bf86e1415b26073d17b2da2dbd2daefd1e

混合 CJS/ESM 构建

随着2023年夏季发行的中断,我们开始将我们的图书馆与两个共同JS(共同JS)一起运送cjs 和建立无害环境管理esm 文件夹,参见 package.json 为详细设置.

如果你使用ES6型的话 import 将在您来自无害环境管理架构的代码文件中使用:

import { EthereumJSClass } from '@ethereumjs/[PACKAGE_NAME]'

如果您使用 Node.js 特定 require,CJS建筑将使用:

const { EthereumJSClass } = require('@ethereumjs/[PACKAGE_NAME]')

使用无害环境管理将比CJS给您更多的优势,超出浏览器的使用范围,如静态代码分析/树摇,CJS无法提供.
