An Ethereum Foundation researcher identified by the handle frisitano has drafted a PeerDAS redesign for variable blob sizes and new checks intended to reduce trusted-setup reliance and improve quantum resistance.
The format would preserve 128 data units per blob across lengths from 2,048 to 524,288 bytes. Permitted lengths would follow powers of two.
Each blob would use Keccak-256 Merkle data and an authentication path in place of KZG objects. LeanDA STARK proofs would reconstruct the root, check Reed-Solomon encoding and compare the commitment with the blob data.
The draft names eliminating a trusted setup and improving resistance to quantum attacks as design goals. Those remain aims in the proposal, not completed changes to Ethereum.
The proposal would also change how execution-layer transactions identify blobs: by Merkle root and byte length instead of a versioned hash. It calls for networking and gas-accounting changes, extending its scope beyond verification.
Ethereum’s post-Hegota plans include separate work on data sampling and quantum safety. A separate draft for a post-quantum key registry for validators and builders was covered earlier by EconoTimes.
