Full 4844 Browser Readiness

WASM KZG

Shortly following the "Dencun Hardfork Support" release round from last month, this is now the first round of releases where the EthereumJS libraries are now fully browser compatible regarding the new 4844 functionality, see PRs #​3294 and #​3296! 🎉

Our WASM wizard @​acolytec3 has spent the last two weeks and created a WASM build of the c-kzg library which we have released under the kzg-wasm name on npm (and you can also use independently for other projects). See the newly created GitHub repository for some library-specific documentation.

This WASM KZG library can now be used for KZG initialization (replacing the old recommended c-kzg initialization), see the respective README section from the tx library for usage instructions (which is also accurate for the other using upstream libraries like block or EVM).

Note that kzg-wasm needs to be added manually to your own dependencies and the KZG initialization code needs to be adopted like the following (which you will likely want to do in most cases, so if you deal with post Dencun EVM bytecode and/or 4844 blob txs in any way):

import { loadKZG } from 'kzg-wasm'
import { Chain, Common, Hardfork } from '@​ethereumjs/common'

const kzg = await loadKZG()

// Instantiate `common`
const common = new Common({
  chain: Chain.Mainnet,
  hardfork: Hardfork.Cancun,
  customCrypto: { kzg },
})

Manual addition is necessary because we did not want to bundle our libraries with WASM code by default, since some projects are then prevented from using our libraries.

Note that passing in the KZG setup file is not necessary anymore, since this is now defaulting to the setup file from the official KZG ceremony (which is now bundled with the KZG library).

Trie Node.js Import Bug

Since this fits well also to be placed here relatively prominently for awareness: we had a relatively nasty bug in the @ethereumjs/trie library with a Node.js web stream import also affecting browser compatibility, see PR #​3280. This bug has been fixed along with these releases and this library now references the updated trie library version.

Other Changes

• TypeScript type fixes leading to build problems with certain tools (Vercel), PR #​3306
• Early support for EIP-2935 - "Save historical block hashes in state" (Verkle related, likely subject to change), PRs #​3268 and #​3327

v4.2.0: @​ethereumjs/tx v4.2.0

Compare Source

This release is part of a final planned release round for the current major EthereumJS release versions, with next major versions planned to be released in July 2023.

It mainly removes all non-final EIP-4844, KZG and SSZ code from the libraries (mainly block, tx, util, evm, vm, blockchain) - see PR #​2721 - to allow for a clean slate for the current major versions to transition to maintenance mode. In particular the @chainsafe/ssz dependency is removed from the @ethereumjs/util library, which is a dependency of all other upstream EthereumJS libraries and removal therefore makes the whole stack lighter again.

If you are interested in continuously following EIP-4844 work have a look at and follow our upcoming breaking releases where major changes will be integrated with 4844 nearing a final state.

Other Changes:

• Fix EIP-155 transaction encoding on chain ID 0 for legacy txs, PR #​2671

v4.1.0: @​ethereumjs/common v4.1.0

Holesky Testnet Support

This release comes with full support for the Holesky public Ethereum testnet replacing the Goerli test network.

• Add Holesky chain specification, PR #​2982, #​2989, #​2997, #​3049, #​3074 and #​3088

EIP-7516 BLOBBASEFEE Opcode

This release supports EIP-7516 with a new BLOBBASEFEE opcode added to and scheduled for the Dencun HF, see PR #​3035 and #​3068. The opcode returns the value of the blob base-fee of the current block it is executing in.

Dencun devnet-11 Compatibility

This release contains various fixes and spec updates related to the Dencun (Deneb/Cancun) HF and is now compatible with the specs as used in devnet-11 (October 2023).

• Update EIP-4788: do not use precompile anymore but use the pre-deployed bytecode, PR #​2955
• Small Cancun-related fixes, PR #​3099

Bugfixes

• Updates and fixes along Geth genesis file parsing, PR #​2961
• Handle forkHash on timestamp == genesis timestamp, PR #​2959

Other Changes

• Performance: Cache Parameter Values + activated EIPs for current Hardfork, PR #​2994

v4.0.0: @​ethereumjs/common v4.0.0

Final release version from the breaking release round from Summer 2023 on the EthereumJS libraries, thanks to the whole team for this amazing accomplishment! ❤️ 🥳

See RC1 release notes for the main change description.

Following additional changes since RC1:

JSON -> JS for Hardfork, EIP and Chain Configs

We have switched hardfork, EIP and chain configurations in the Common library from JSON to JavaScript (TypeScript). This leads to better typing (and therefore less configuration errors) for (custom) configuration files and avoids JSON type assertion related problems for ESM builds, see PR #​2911.

Following changes:

• src/chains/[CHAIN_FILE].json -> src/chains.ts
• src/eips/[EIP_FILE].json -> src/eips.ts
• src/hardforks/[HARDFORK_FILE].json -> src/hardforks.ts

Other Changes

• 4844: Rename dataGas to blobGas (see EIP-4844 PR #​7354), PR #​2919
