TRON activates quantum-resistant signatures on Nile testnet

The TRON blockchain network has activated a quantum-resistant security feature on its Nile testnet, deploying new cryptographic signatures designed to protect against future threats from advanced quantum computers. The upgrade, implemented via a mandatory software build, introduces support for post-quantum algorithms standardized by the U.S. National Institute of Standards and Technology (NIST).

The network's development organization announced the deployment of build GreatVoyage-v4.8.2-PQ1-build1, which integrates support for two signature schemes: FNDSA512 (based on the Falcon512 standard) and MLDSA44 (a variant of CRYSTALS-Dilithium). The activation followed the approval of a specific on-chain committee proposal, numbered 20628, on July 2, 2026. The new functionality covers several core network operations, including transaction signing, block production by super representatives, peer-to-peer node handshakes, and signature verification within the TRON Virtual Machine for smart contracts.

TRON founder Justin Sun publicly endorsed the move, stating the network aims to be the first quantum-resistant blockchain and calling post-quantum security a central demand of the artificial...
