On November 1 (UTC+8), Ethereum Foundation researcher frisitano published a draft EIP titled "Post-Quantum PeerDAS and Variable-Size Blobs." The proposal replaces KZG commitments and proofs with Keccak-256 Merkle commitments and authentication paths, combined with zero-knowledge proofs (ZKPs) via LeanDA STARKs to eliminate trusted setups and enhance quantum resistance. It also introduces variable-size blobs (with byte lengths as powers of two ranging from 2048 to 524288), maintaining 128 data units but varying in size. Execution layer transactions will include (merkle_root, byte_length), alongside modifications to the network layer and gas billing.

ME News reports that on November 1 (UTC+8), Ethereum Foundation researcher frisitano released a draft EIP titled "Post-Quantum PeerDAS with Variable-Sized Blobs." The draft replaces the KZG commitments and proofs in PeerDAS with Keccak-256 Merkle commitments and authentication paths for each blob, combined with LeanDA STARK proofs (which recalculate the Merkle root, verify Reed-Solomon encoding relationships, and confirm the match between commitments and data) to eliminate trusted setups and enhance quantum resistance.
The draft also introduces variable-sized blobs (with byte lengths that are powers of two between 2048 and 524288, and divisible by 128 columns), maintaining 128 data units but adjusting size according to the blob. Execution-layer transactions will carry (merkle_root, byte_length) instead of a versioned hash, and the network layer and gas billing mechanisms will be updated accordingly. (Source: Foresight News)
