Public Chains Prepare for Post-Quantum Security Amid Quantum Computing Threat

1 reports1 sources11/5/2026 updated

Current overview (not historical)

AI overview

Odaily reported that quantum computing poses a potential threat to the cryptography underpinning Bitcoin, Ethereum and other public blockchains, while current quantum hardware has not yet created an actual danger. Several chains have already begun post-quantum security preparations. Algorand, NEAR and Starknet have launched post-quantum accounts, and Ethereum targets completion of its post-quantum migration around 2029. Bitcoin-related proposals remain at the draft stage. NIST has released post-quantum standards, and institutional investors including BlackRock and VanEck have disclosed quantum risks in ETF prospectuses.
