Vitalik Buterin outlined Ethereum’s quantum resistance roadmap, identifying four components currently vulnerable to quantum attacks: consensus-layer BLS signatures, data availability based on KZG commitments, EOA signatures, and application-layer zero-knowledge proofs. Quantum resistance aims to ensure Ethereum remains cryptographically secure from quantum computers. For the consensus layer, the roadmap proposes replacing BLS signatures with hash-based signature schemes and using STARKs for signature aggregation. In data availability, Ethereum may move away from KZG commitments toward STARK-based constructions. For EOAs, the plan is to migrate to native Account Abstraction. For zero-knowledge proofs, the long-term solution is protocol-level recursive aggregation.
Ethereum Foundation cryptography researchers introduced leanSig, a post-quantum, hash-based multi-signature scheme designed to replace Ethereum’s current BLS-based signature aggregation in the consensus layer. leanSig is built from one-time signatures (OTS) constructed using hash chains. Since each one-time key can only be used once, validators commit to a large set of OTS public keys via a Merkle tree. Each signature consists of a one-time signature plus a Merkle proof, effectively creating a many-time signature scheme suitable for Ethereum’s slot-based consensus. Unlike BLS, hash-based signatures lack algebraic structure and therefore cannot be natively aggregated. To achieve aggregation, leanSig uses a SNARK to prove knowledge of many valid signatures. The resulting SNARK proof serves as the aggregate signature, replacing BLS-style aggregation while remaining quantum resistant.
Alchemy launched Crypto APIs for Agents, allowing AI agents to autonomously authenticate, pay, and access onchain data across chains. Agents authenticate with their wallet via SIWE, then call Alchemy’s agentic gateway. The gateway responds with an HTTP 402 payment request, which the agent fulfills in USDC via x402. Once payment is made, API access continues automatically until the balance is depleted. Agents can use the service access core RPC endpoints, manage DeFi positions, monitor markets, and execute cross-chain workflows. Alchemy also introduced Alchemy Skills, machine-readable documentation for AI agents.
Brevis announced that Pico Prism zkVM now proves 99%+ of Ethereum L1 blocks in under 12 seconds using just 16 RTX 5090 GPUs, a 75% reduction from its previous 64-GPU setup. This optimization cuts GPU costs from $128k to $32k while maintaining real-time performance. Meanwhile, the Ethereum Foundation aims for 128-bit provable security by the end of 2026.
