Algorand v5.0.0 Adds Native Quantum-Resilient Accounts

Algorand is moving post-quantum security from roadmap language into protocol-level account support.

The Algorand Foundation said on August 16 that version 5.0.0 passed the network’s support threshold and will introduce native Falcon-1024 accounts, resource-based fees, and a larger toolkit for smart-contract developers.

The release is the network’s largest protocol upgrade since staking rewards arrived in January 2025. It reached the required 90% support threshold on August 15 but will not activate immediately: a mandatory 208,000-round cooldown of roughly seven days comes first.

Falcon-1024 Accounts Become Native Version 5.0.0 allows users to create accounts protected by Falcon-1024 post-quantum signatures directly in the protocol. Previously, similar protection required custom logic attached to an account.
