While most blockchain projects are still debating whether quantum computing is a real threat or a sci-fi boogeyman, Algorand is already 140,000 transactions deep into solving the problem.
The Algorand Foundation revealed a comprehensive roadmap on June 18 targeting full quantum resilience for its protocol by the end of 2027. The project has been building toward this since 2022, and it’s now setting specific quarterly milestones to get the job done before national security agencies even require it.
What Algorand has already built, and what’s coming next
Algorand started treating quantum computing like a present problem back in 2022, when the team implemented Falcon-signed State Proofs to protect the blockchain’s historical integrity.
The first post-quantum transaction hit Algorand’s mainnet on November 3, 2025, using Falcon signatures. Since then, over 140,000 such transactions have been processed.
