How Exposed Are Ethereum and Solana to a Potential Quantum Threat?
According to Project Eleven’s newest report, about 65% of Ethereum (ETH) and 100% of Solana (SOL) are quantum-vulnerable.
The newest numbers arrive as blockchains step up efforts to mitigate potential dangers posed by future quantum capabilities.
Ethereum and Solana Quantum Risk Mapped in 2026 Report
Ethereum carries three quantum-vulnerable primitives, in accordance to the report. The Elliptic Curve Digital Signature Algorithm (ECDSA) secures consumer accounts. Boneh-Lynn-Shacham (BLS) signatures deal with proof-of-stake consensus. Kate-Zaverucha-Goldberg (KZG) commitments help blob knowledge launched by EIP-4844.
A quantum attacker recovering validator BLS keys may forge attestations, destabilize consensus, and set off mass slashing throughout the community. Validator BLS keys stay publicly seen from the second of the 32 ETH deposit.

Solana’s vulnerability is structural. Its Ed25519 design embeds every pockets’s public key immediately contained in the on-chain tackle. Bitcoin’s UTXO model offers a partial buffer as a result of unspent, unrevealed keys keep hidden.
“Solana exposes an X-only public key for addresses, rendering all Solana quantum susceptible,” the report learn.
Where the Post-Quantum Migration Plans Stand
Notably, each networks are actively getting ready for potential quantum threats. Developers from the Ethereum Foundation launched a Post-Quantum Ethereum web site in March 2026.
The crew initiatives that Layer 1 (L1) protocol upgrades may end by 2029. Full execution-layer migration would prolong past that date.
In April, Solana Validator client developers Anza and Firedancer independently chosen Falcon. The post-quantum signature scheme is permitted by the National Institute of Standards and Technology (NIST). The Solana Foundation framed its plan as prepared to activate when wanted.
“Quantum continues to be years away, and if and when it materializes, the work to migrate Solana is well-researched, understood, and prepared to deploy,” the crew mentioned.
Project Eleven maps three Q-Day eventualities. 2030 is the optimistic case, 2033 the average, and 2042 the pessimistic. The agency cautions that its projection assumes solely modest year-over-year enchancment and no major breakthroughs.
