TRON had advanced its post-quantum security efforts, including deploying end-to-end post-quantum signature support on the Nile testnet, TRON founder Justin Sun said during a fireside chat with When Shift Happens founder Kevin Follonier.
The crypto entrepreneur said the network is closely following progress in quantum computing and AI and can bring quantum-resistant protections to mainnet at any time.
TRON's post-quantum cryptography is now live on testnet. We're closely tracking progress in quantum computing and AI, and we're ready to bring quantum resistance to mainnet at any time. We're committed to keeping user assets secure, and TRON is set to be one of the few major… — H.E. Justin Sun 👨🚀 🌞 (@justinsuntron) October 10, 2026
He added that TRON aims to become one of the few major blockchains to implement quantum resistance before Q-Day, when sufficiently advanced quantum computers could potentially derive private keys from exposed public keys.
TRON’s Nile testnet enabled its first post-quantum signature algorithm, FN-DSA-512, earlier this year, opening the feature to developers for testing, Sun disclosed in July.
TRON plans to upgrade its entire network to quantum-resistant security by the end of 2026, Sun said at Bitcoin Asia 2026 in Hong Kong in August. Sun said the network had spent the previous year developing quantum-resistant mechanisms and released a quantum-resistant address solution in the first half of 2026.
