I wrote a simple EVM assembly code to support DATAHASH (0x49) opcode and a solidity library to use the assembly https://github.com/ethstorage/eip4844-blob-hash-getter. I hope that this may reduce the efforts of developers to experiment with BLOBs.

Tested the code by setting up an EIP-4844 devnet following https://hackmd.io/@jimmygchen/H1XUtBIfn from lighthouse. Both the devnet and contract code work as expected as the 4844's spec.

Nice! thanks for sharing!

Another (tiny) spec update from Etan: ethereum/EIPs#6503

[roberto-bayardo]

And lastly I believe Etan is out today but maybe we could discuss his question here about whether we should use opaque signature format (the format expected by the crypto libraries) in the SSZ rather than splitting out v,r,s
