Coinbase's Quantum Advisory Council released a position paper this week naming Aptos and Algorand as the blockchains best positioned for post-quantum security. The assessment comes as the crypto industry grapples with the looming threat of quantum computers breaking current cryptographic standards.
The two chains that made the cut
The council evaluated a range of blockchain networks and singled out Aptos and Algorand as the most prepared. Both chains have long emphasized cryptographic agility — the ability to swap in new algorithms as threats evolve. The position paper doesn't detail the exact criteria, but the nod signals that these two projects are ahead of peers in quantum readiness.
Why the council's opinion matters
Coinbase's Quantum Advisory Council includes cryptographers and quantum computing researchers. Their endorsement carries weight because the exchange handles billions in digital assets. If quantum computers mature faster than expected, the first targets will be blockchains with static, quantum-vulnerable signatures. The council's work is meant to guide not just Coinbase but the broader industry on which networks to trust long-term.
The road to quantum-safe crypto
Neither Aptos nor Algorand is fully quantum-proof today. But both have built-in upgrade paths — Aptos through its Move language and Algorand through its state proofs and signature schemes. The council's paper is a signal that developers should start planning for a post-quantum world now, not after a breakthrough. The next step is likely a more detailed technical roadmap from the council, though no date has been set.
