Algorand 5.0 Upgrades Blockchain Security with Post-Quantum Signatures

Algorand has officially launched its version 5.0 upgrade, marking a significant step forward in blockchain security and scalability.

The headline feature is native support for post-quantum signatures using Falcon-1024, a lattice-based cryptographic scheme designed to withstand attacks from quantum computers.

This upgrade eliminates previous limitations that hindered DeFi composability when multiple transactions were required for verification.
