According to the latest Project Eleven report, about 65% of Ethereum (ETH) and 100% of Solana (SOL) are quantum vulnerable.
The latest numbers arrive as blockchains ramp up efforts to mitigate potential risks posed by future quantum capabilities.
Quantum risks for Ethereum and Solana are set to report in 2026
According to the report, Ethereum holds three quantum-vulnerable primitives. Elliptic Curve Digital Signature Algorithm (ECDSA) secures user accounts. Boneh-Lynn-Shacham (BLS) signatures deal with proof-of-stake consensus. The Kate-Zaverucha-Goldberg (KZG) commitments support the large point data presented by EIP-4844.
Quantum attacker Restore the auditor BLS keys can forge certificates, destabilize consensus, and cause mass shutdowns across the network. Validator BLS keys remain visible to the public from the moment 32 ETH is deposited.

Solana’s weakness is structural. Its Ed25519 design includes each wallet’s public key directly inside the on-chain address. Bitcoin UTXO The form is submitted partially Buffer because unspent and unexposed keys remain hidden.
“Solana only exposes public key
Where do post-quantum migration plans stand?
It is worth noting that both networks are actively preparing for potential quantum threats. Ethereum Foundation developers launched a post-quantum Ethereum website in March 2026.
The team expects Layer 1 (L1) protocol upgrades to be completed by 2029. The full implementation layer migration will extend beyond that date.
In April, Solana Validator Anza Customer Developers and Firedancer chose the falcon independently. The post-quantum signature scheme has been approved by the National Institute of Standards and Technology (NIST). The Solana Foundation has positioned its plan as ready to be activated when needed.
“We are still many years away from reaching quantum, and when that is achieved, the work to migrate Solana will be well thought out, understood, and ready for deployment,” the team said.
Project Eleven paints three scenarios for Q-Day. 2030 is the optimist, 2033 is the moderate, and 2042 is the pessimist. The company cautions that its forecast assumes only modest improvement year-over-year No major breakthroughs.
