On April 21, 2026, Coinbase’s Quantum Advisory Council released a position paper naming Aptos and Algorand as the two blockchain networks best positioned to handle the cryptographic challenges that quantum computers will eventually bring. Its advisory group includes Scott Aaronson from UT Austin and Dan Boneh from Stanford University, two of the most cited names in cryptography and quantum computing research.
What makes Aptos different here
Most networks today secure wallets using elliptic curve cryptography. A sufficiently powerful quantum computer could, in theory, reverse-engineer private keys from public ones.
Aptos was built with this transition in mind from day one. Launched in 2022, it runs on the Move programming language and uses a modular cryptographic infrastructure. If Aptos needs to swap out its signature scheme, it can do that in a single transaction without asking users to create new accounts or move their assets anywhere.
The Coinbase council’s paper specifically highlighted this crypto-agility as Aptos’s central advantage. Crypto-agility means a system’s ability to swap cryptographic primitives without disrupting the broader network.
