Tron says post-quantum signatures are ready for mainnet after Nile testnet activation

Tron Confirms Post-Quantum Signatures Ready for Mainnet Activation

Post-Quantum Signatures on Tron's Mainnet

Tron's founder, Justin Sun, has confirmed that the network is ready to implement post-quantum cryptography on its mainnet after successful testing on the Nile testnet.

Background and Motivation

The testnet upgrade arrived on July 2, 2026, through Committee Proposal No. 20628 and shipped with the GreatVoyage-v4.8.2-PQ1-build1 release.

Two Signature Algorithms Involved

Two signature algorithms are involved, and both carry NIST standardization: FN-DSA-512 and ML-DSA-44.

Key Features

The new signatures reach transaction signing, block production, peer-to-peer handshakes between nodes, and smart contract verification inside the Tron Virtual Machine.

Challenges Ahead

However, the implementation of post-quantum signatures also comes with challenges, such as increased transaction size and potential impact on throughput and storage costs.

Governance and Mainnet Activation

Mainnet activation still requires separate approvals from Tron's governance bodies, and the end-of-2026 target is the benchmark.

Conclusion

Tron's move to implement post-quantum signatures is a significant step towards ensuring the long-term security of its network, and it places the network among the early movers on end-to-end quantum resistance.
