Beef about Bitcoin post-quantum cryptography upgrade: Mow dey warn on timing and blocksize risks
Debet bout Bitcoin post-quantum cryptography (PQC) upgrade don dey hot as stakeholders dey look towards 2029 migration deadline. JAN3 founder Samson Mow knack Coinbase Brian Armstrong say e dey push make dem switch to PQ sooner, e talk say if dem change wey dem never test e fit expose BTC to attacks from classical computers wey dey now.
Mow main technical worry be say PQ signatures fit big well well (estimate 10–125x). Big signatures fit make blocks need to dey bigger, reduce transactions per block, and fit reduce throughput — people dey fear say e fit turn to another "blocksize wars 2.0" kind wahala. E mention say some claims talk say if dem use current PQ approaches e fit slow Solana down plenty (about 90% slowdown), show say impact go pass only Bitcoin — e go affect scalability generally.
This fight dey gain momentum after Google Quantum AI report wey suggest crypto security fit weaken sooner than dem think. Google estimate say quantum processors fit need ~500,000 physical qubits or 1,200–1,450 stable logical qubits to break security, and dem warn say as many as ~7 million BTC wey dey tied to vulnerable keys fit dey at risk on shorter timeline.
No be everybody dey fear. Zach Pandl from Grayscale talk say quantum computers no be immediate threat to public blockchains, but make dem prepare faster. Meanwhile, Charles Edwards talk say BTC fit hard to reach new all-time high without PQ migration, while Adam Back say scalable physical quantum hardware fit still dey some years away.
For traders, this news no too dey about immediate hack threat but na about how governance and protocol changes under timing pressure fit affect BTC long-term security posture and how network performance go dey expected.
Neutral
Di mix articles dem frame di mata as governance and protocol timing risk no be say Bitcoin security don break now. Mow warning dem dey show say if Bitcoin rush to use post-quantum cryptography e fit cause scalability and compatibility wahala, and Google report dey raise alarm say progress fit make vulnerable keys risky for shorter timeline. But plenty commentators (e.g., Grayscale) talk say no direct near-term threat, so e reduce chance say price go sharply move one way. Net effect: sentiment fit sway with headlines about “blocksize wars 2.0” and migration urgency, but because no immediate exploit, price impact on BTC likely go moderate and range-bound—so neutral.
