Tron founder Justin Sun announced this week that the network is officially launching a post-quantum upgrade initiative, positioning the move as a first-mover play in a growing industry race to defend against future quantum computing attacks.

Sun on April 14 on X said Tron would adopt NIST-standardized post-quantum cryptographic signatures on its mainnet, aiming to become the first major public blockchain to deploy the technology. 

“While Bitcoin debates whether to freeze vulnerable coins and Ethereum forms research committees,” he wrote, “Tron is building.”

Sun’s remarks come as Bitcoin developers are actively debating two competing quantum proposals: the controversial BIP-361, which would impose a five-year migration deadline and freeze unmigrated coins, and a newer BitMEX Research “canary fund” alternative that would trigger a freeze only after an attacker proves the threat on-chain. Ethereum remains at the research stage.

The Tron network secures more than $5 billion in on-chain value and roughly $86.7 billion in stablecoins, primarily Tether’s USDT. Protecting that infrastructure gives the initiative real financial weight beyond marketing positioning. 

Tron’s delegated proof-of-stake model, which relies on just 27 validators, may provide a coordination advantage over more decentralized networks during any migration. The engineering challenges are real, however. Post-quantum signatures can be 10 to 121 times larger than current ECDSA signatures, increasing storage and bandwidth demands substantially. As of April 15, no formal governance proposal or technical documentation had been released by Tron DAO. 

TRX traded near $0.33 following the announcement, with active addresses climbing to a two-week high of 3.04 million on April 15, according to DeFiLlama data.
