TRON founder Justin Sun announced that the network was preparing for an era of quantum computing. The test version with post-quantum cryptography is planned to be launched in the second quarter of 2026, and the main network - in the third. Such a step, according to Sana, should make TRON the first large blockchain, resistant to potential threats from powerful quantum computers that are theoretically capable of cracking modern encryption algorithms.

While such risks remain hypothetical, leading market players are already in the race. The Ethereum Foundation is assessing whether to complete basic upgrades by 2029, Solana is testing post-quantum digital signatures, Coinbase has created a quantum security advisory board, and Google is targeting a new cryptography for 2029. Against this background, TRON’s claims appear to be among the most ambitious in terms of timing.

But migration to quantum-stable tracks is not just a blockchain challenge. Wallets, exchanges, and smart contracts will need to be adapted, which could stretch the process. In addition, new algorithms are still more resource-intensive and likely to affect network capacity, so implementation is being phased in - from tests to partial, and then full replacement.
