StarkWare researcher Avihu Levy unveils Quantum Safe Bitcoin (QSB), replacing signatures with hash proofs. No protocol upgrade needed, but each transaction costs $75–$200 and requires direct miner contact.
Google Quantum AI's new whitepaper says breaking Bitcoin only needs 1,200 logical qubits—20x lower than prior estimates—with quantum hardware expected by 2033. The real crisis is not physics but Bitcoin's conservative governance, as anti-quantum upgrades would halve throughput and triple fees, with consensus potentially taking a decade.
Benchmark says quantum computing is a real long-term risk for Bitcoin, but not an immediate one. The firm points to ECDSA rather than SHA-256 as the main weak spot, while arguing the network still has time to adapt.
A new Google Quantum AI paper says breaking elliptic curve cryptography may require far fewer quantum resources than earlier estimates, raising pressure on crypto networks to prepare post-quantum upgrades before the end of the decade.
NEAR has rolled out mainnet version 2.13.0, adding ML-DSA-65 post-quantum signatures, automatic shard splitting, NEP-611 gas keys, and peer-to-peer node sync.
A new White House executive order accelerates the U.S. federal transition to post-quantum cryptography to December 2031, with NIST pilot migrations due by 2027. Analysts warn that roughly 7 million BTC could be at risk from future quantum attacks.
Ethereum co-founder Vitalik Buterin published a comprehensive quantum-resistance roadmap, identifying four vulnerable areas and pushing frame transactions for the Hegota upgrade in H2 2026.
StarkWare researcher Avihu Levy has proposed Quantum Safe Bitcoin, a design aimed at protecting Bitcoin from quantum attacks without a soft fork, though estimated transaction costs run from $75 to $150 each.
