Bitcoin (BTC) Post-Quantum Signatures Progress: BitMEX Research Chart of Signature Sizes and Proposal Dates (2025 Update)
According to BitMEX Research, there has been significant technological progress in quantum-resistant signature schemes that Bitcoin could use, as reported in a Dec 23, 2025 thread (source: BitMEX Research, Dec 23, 2025). BitMEX Research shared a chart showing the signature sizes in bytes and the dates these schemes were proposed for Bitcoin, providing concrete data points for assessing potential on-chain data overhead if any scheme is later evaluated by developers (source: BitMEX Research, Dec 23, 2025). The post does not announce any activation, adoption, or timeline, indicating no immediate protocol catalyst from this update alone for BTC price action (source: BitMEX Research, Dec 23, 2025). |

Bitcoin (BTC) Quantum Risk Debated Since 2011 on Bitcointalk: Trader Watchpoints on ECDSA and NIST PQC
According to BitMEX Research, the Bitcoin community was already debating quantum-computing risks in January 2011 on Bitcointalk, highlighting long-standing awareness of potential cryptographic threats to BTC security, Source: BitMEX Research post on X dated Dec 23, 2025, Bitcointalk forum discussion. The core technical issue is that Bitcoin’s ECDSA signatures would be vulnerable to sufficiently powerful quantum computers via Shor’s algorithm, prompting global efforts to adopt post-quantum cryptography, Source: NIST Post-Quantum Cryptography project. Traders evaluating tail risk can track two concrete signals grounded in this context, the maturation of NIST-standardized post-quantum signature schemes and any Bitcoin developer discussions about quantum-resistant signature options, as proxies for mitigation progress rather than immediate protocol change, Source: NIST Post-Quantum Cryptography project, Bitcointalk forum discussion. |
