Coinbase Says Bitcoin’s Post-Quantum Transition Will Take Years

Coinbase wants to prepare Bitcoin for the arrival of quantum computers without waiting for them to become a concrete threat. In a publication dated October 13, the platform emphasizes that modifying the network rules and supporting the migration of its ecosystem will take several years. It claims to hold nearly one million BTC, about 5% of existing bitcoins. Its document presents technical avenues, not a plan imposed on the network. Coinbase does not simply recommend replacing current signatures. The platform rather wants to create an architecture capable of hosting different post-quantum protection mechanisms without disrupting the network. This approach makes all the more sense as an open competition reduced the cost of a quantum-resistant transaction from $320 to $67 in September.
