Overview
- Tron deployed end‑to‑end post‑quantum signature support as an opt‑in upgrade on the Nile testnet that shipped with Committee Proposal No. 20628 on July 2, 2026.
- Founder Justin Sun said on October 10 that the network is technically ready to enable the post‑quantum features on mainnet whenever governance approves the change.
- Mainnet activation still requires separate votes from Tron’s governance bodies and the project has pushed its original Q3 target to the end of 2026.
- The chosen algorithms are NIST‑standard Falcon‑512 (FN‑DSA‑512) and a Dilithium‑based scheme (ML‑DSA‑44), which produce much larger signatures—Falcon‑512 can be about 667 bytes—and could raise throughput, storage and address‑migration costs.
- Security experts have urged rigorous internal testing and independent external audits before any mainnet rollout because the upgrade affects transaction signing, block production, node handshakes and smart contract verification and aims to protect users’ wallets and large stablecoin holdings.
