@​ethereumjs/common v4.3.0

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
