description: "Project Eleven's report reveals significant quantum vulnerabilities in Ethereum (ETH) and Solana (SOL), with 65% of Ethereum and 100% of Solana at risk. Ethereum's issues are linked to its use of ECDSA, BLS signatures, and KZG commitments, while Solana's vulnerability is due to its Ed25519 design exposing public keys. Both networks are preparing for quantum threats, with Ethereum planning Layer 1 upgrades by 2029 and Solana ready to implement post-quantum solutions as needed."

# Project Eleven: Ethereum and Solana Face Quantum Vulnerability Risks

Project Eleven's latest report highlights significant quantum vulnerabilities in Ethereum (ETH) and Solana (SOL), with 65% of Ethereum and 100% of Solana deemed at risk. According to BeInCrypto, Ethereum's vulnerabilities stem from its use of the Elliptic Curve Digital Signature Algorithm (ECDSA), Boneh-Lynn-Shacham (BLS) signatures, and Kate-Zaverucha-Goldberg (KZG) commitments. Solana's structural vulnerability arises from its Ed25519 design, which exposes public keys directly in on-chain addresses. Both networks are actively preparing for quantum threats, with Ethereum targeting Layer 1 protocol upgrades by 2029 and Solana ready to deploy post-quantum solutions when necessary.
