Coinbase Outlines Flexible-Design Priority for Bitcoin’s Post-Quantum Security Shift

The exchange, which reportedly holds about 5% of all bitcoin in circulation, is pushing for adaptable cryptographic upgrades ahead of any quantum computing threat. Coinbase has laid out its thinking on how Bitcoin should prepare for a future in which quantum computers could threaten existing cryptographic protections. According to reporting from The Block, the exchange identified flexible design choices as a central priority in any migration plan. The goal is to avoid locking the network into a single technical approach before the scale and timeline of the quantum threat are fully understood.
