Tron to Deploy NIST Post-Quantum Signatures on Mainnet

Justin Sun announced Wednesday that Tron will deploy NIST-standard post-quantum signature schemes on its mainnet as part of an upgrade designed to protect users' assets from potential quantum-computing threats.

Sun described the plan as making Tron the first mainstream public chain to put NIST-approved post-quantum signature algorithms into production on its main network. He wrote that Tron began work before other major chains formalized their plans and added that ‘quantum security shouldn't be a debate; it should be a feature.' Sun also said the project will publish a technical roadmap soon.

The announcement follows a recent paper from Google Quantum AI that renewed debate over the timeline for quantum attacks on modern cryptography. Google has set a 2029 target for migration to post-quantum cryptography in some contexts, prompting developers and network operators to plan upgrades.

Binance founder Changpeng Zhao argued upgrades to quantum-resistant algorithms are feasible and warned against panic, saying ‘at a high level, all crypto has to do is upgrade.' Ethereum researcher Justin Drake urged caution in interpreting recent results, calling timelines for practical quantum attacks probabilistic and estimating a small but meaningful chance that elliptic-curve keys could be broken by the early 2030s.

Tron hosts significant stablecoin and decentralized finance activity. More than $80 billion in stablecoins, primarily USDT, have been issued on Tron, and the protocol's total value locked is about $5 billion. Those figures describe the scale of assets tied to the network.

The announced plan centers on implementing signature schemes selected through the U.S. National Institute of Standards and Technology's post-quantum standardization process. Replacing current elliptic-curve signatures typically involves client software updates, coordinated participation by validators and node operators, and migration tools for key management and wallet support.

Sun did not provide a specific rollout date and added the technical roadmap will be released soon. The goal of the upgrade is to reduce the risk that future advances in quantum computing could compromise users' private keys.

NIST's standardization effort aims to select algorithms intended to remain secure against both classical and quantum attacks. Several blockchain projects and infrastructure providers have discussed or begun planning transitions to quantum-resistant cryptography.
