The Algorand Foundation has published a post-quantum security roadmap targeting broad quantum resilience across its entire blockchain network by the end of 2027.
The plan covers every layer of the protocol — from user wallets and developer tooling to the consensus mechanisms that validate transactions — with the first milestones scheduled to begin in Q3 2026.
What Post-Quantum Security Actually Means Post-quantum cryptography refers to encryption methods designed to withstand attacks from quantum computers, which are expected to eventually break the mathematical puzzles that underpin most of today's digital security.
For a public blockchain, the exposure is acute: cryptographic keys protect every wallet, and the algorithms that confirm transactions are woven into the network's foundation.
