Tron post-quantum cryptography is live on testnet, mainnet needs governance approval
Image: CointelegraphTron founder Justin Sun announced the network's post-quantum cryptography is live on the Nile testnet as of early July 2026. The testnet uses NIST-standardized FN-DSA-512 and ML-DSA-44 digital signatures that cover transaction signing, block production, peer-to-peer node handshakes and smart contract verification. Larger signature sizes may affect throughput and storage costs, which the testnet is designed to surface. Mainnet activation still requires separate governance approval, and the feature remains fully opt-in on testnet for now.
Key points
- Mainnet activation of the feature requires separate Tron governance approval
- The post-quantum feature remains fully opt-in and confined to testnet for now
Why it matters
If approved for mainnet, the upgrade would make Tron one of the first major blockchains with end-to-end quantum resistance. Larger post-quantum signatures may impact network throughput and storage costs, which testnet testing aims to identify.
What's unclear
The exact timeline for Tron's mainnet governance vote on the post-quantum upgrade is not specified
Whether the post-quantum feature will remain opt-in or be mandatory on mainnet if approved is not stated
