peerdas

An update to our previous coverage of quantum cryptography: A new EIP draft proposes replacing KZG proofs in PeerDAS with Merkle paths and STARK proofs, with varying blob data sizes. It’s still an early proposal under review, with no activation date. Do you expect it to change the ETH scaling debate? 🧩🔐📦 $ETH #Ethereum #PeerDAS

Came across this on TokenPost / Foresight: Ethereum Foundation researcher frisitano has released an EIP draft for “post-quantum PeerDAS + variable-size Blobs.”

Key technical points: PeerDAS is proposed to use per-Blob Keccak-256 Merkle commitments and authentication paths, replacing the current KZG commitments/proofs, alongside LeanDA STARKs (recomputing Merkle roots, checking Reed-Solomon, and verifying commitments against data). The goal is to eliminate trusted setup and improve quantum resistance. Blob byte lengths are proposed to range from about 2048 to 524288 (powers of 2), retaining 128 data cells while allowing the overall size to vary. Execution-layer transactions would carry (merkle_root, byte_length) instead of a versioned hash, requiring changes to the networking layer and gas accounting too. This is a draft, not something that has been deployed.

The post-Hegota roadmap already prioritizes data sampling and quantum security—this kind of foundational draft is worth keeping an eye on.

Ethereum Foundation researcher frisitano has submitted an EIP draft aiming to upgrade PeerDAS with a “trustless setup + quantum resistance.”

Key change: Replace Blob KZG commitments and proofs with Keccak-256 Merkle commitments and authentication paths. LeanDA STARK proofs would then recompute the Merkle root, verify Reed-Solomon encoding relationships, and confirm that the commitment matches the data. This would eliminate reliance on a KZG trusted setup while improving security against future quantum computing.

The draft also introduces variable-size Blobs: their byte length must be between 2048 and 524288, be a power of 2, and be divisible by 128 columns. Execution-layer transactions would carry (merkle_root, byte_length) instead of using versioned hashes, with corresponding changes to the network layer and Gas accounting.

If adopted, this would make Rollup data submissions better suited to actual needs and enable more precise use of Blob resources. However, this is still a draft, and the parameter design, compatibility, and security require further discussion.$ETH #以太坊 #EIP #PeerDAS

Vitalik Buterin suggests PeerDAS is the catalyst that evolves Ethereum from a standard blockchain into a massive technological powerhouse.
