# Cryptocurrency Industry Should Begin Post-Quantum Migration Now, Coinbase Advisory Board Warns
While quantum computers capable of breaking current blockchain encryption aren’t here yet, the cryptocurrency sector shouldn’t wait to prepare, according to a new Coinbase-commissioned report. The analysis, assembled by leading quantum and cryptography experts, concludes that fault-tolerant quantum machines will eventually emerge—despite formidable engineering challenges—making early action prudent.
The primary obstacle isn’t finding post-quantum solutions; NIST has already standardized quantum-resistant algorithms. The challenge lies in integration. Post-quantum signatures are dramatically larger than current ones (2,400+ bytes versus 64 bytes), potentially slashing blockchain throughput and raising transaction fees. Proof-of-stake systems relying on compressed aggregate signatures face particular difficulties.
The board recommends phased migration strategies—such as adding post-quantum checkpoints to existing chains—rather than abrupt overhauls. They emphasize crypto-agility (building cryptographic flexibility into protocols) and warn that dormant wallets pose difficult governance questions about inaccessible funds.
The consensus: prepare deliberately now rather than frantically later.
