TRON has activated post-quantum cryptography on its Nile testnet, marking a major step toward stronger blockchain security ahead of potential future quantum computing threats. The upgrade resulted from Committee Proposal No. 20628 and was implemented through the mandatory GreatVoyage-v4.8.2-PQ1-build1 node upgrade.
The new system introduces post-quantum cryptography, or PQC, designed to protect digital information from powerful quantum computers. The testnet deployment includes two lattice-based digital signature algorithms: FN-DSA-512, also known as Falcon-512, and ML-DSA-44, commonly called Dilithium. Falcon-512 will serve as the primary signature algorithm for live testnet tests, while ML-DSA-44 is available as an alternative.
TRON's approach extends beyond ordinary wallet transactions. The protection is planned for transaction signing, block production, peer-to-peer networking, and smart contract verification. The TRON Virtual Machine, where smart contracts run, will also benefit from quantum-resistant signature verification. Developer testing on the Nile testnet will focus on compatibility, performance, reliability, and potential security vulnerabilities before any mainnet release.
TRON founder Justin Sun shared the update on X on October 10, emphasizing that TRON was monitoring advancements in quantum computing and AI. At TOKEN2049 Singapore and Blockworks Digital Asset Summit Asia 2026, Sun discussed stablecoins, institutional adoption, AI-driven commerce, machine-to-machine payments, and the need for quantum-resilient blockchain infrastructure. He also highlighted TRON's role as a global settlement layer for stablecoin transactions and predicted that AI agents using crypto will become the industry's biggest use case within five years.
