Vitalik Buterin outlined a roadmap to strengthen Ethereum against quantum threats, covering upgrades to consensus-layer BLS signatures, data availability via KZG commitments, EOA security beyond ECDSA, and quantum-resilient application-layer zkps such as KZG and Groth16.

Now, the quantum resistance roadmap. Today, four things in Ethereum are quantum-vulnerable: * consensus-layer BLS signatures * data availability (KZG commitments+proofs) * EOA signatures (ECDSA) * Application-layer ZK proofs (KZG or groth16) We can tackle these step by step:

Ethereum Foundation researchers introduced leanSig, a hash-based, post-quantum multi-signature scheme to replace BLS aggregation in Ethereum’s consensus layer.

Thomas Coratger@tcoratger

1/12 Ethereum's consensus layer relies heavily on BLS signature aggregation, but BLS is vulnerable to quantum attacks. Enter leanSig: a hash-based, post-quantum multi-signature scheme. Decryption of the last @zeroknowledgefm session with @nico_mnbl, @Khovr and Benedikt 🧵👇
