Tron founder Justin Sun said the network’s post-quantum cryptography has gone live on testnet, adding that the blockchain is ready to bring quantum resistance to mainnet at any time. In a post on X published Saturday, Sun said the team is watching advances in quantum computing and AI closely and aims for TRON to be among the few major blockchains that are quantum-resistant before the arrival of “Q-Day,” the point at which quantum machines could break current security standards.
The update comes as work on post-quantum security gains traction across the crypto sector. A July 28 CoinDesk report said blockchain security firm AmericanFortress introduced a cryptographic plan designed to protect crypto wallets from future quantum attacks without requiring users to move funds, rotate keys or change wallet addresses. The company said the proposal differs from many other post-quantum approaches because it preserves existing wallet addresses while adding post-quantum protection. The plan has been published as a technical paper on the Cryptography ePrint Archive, though it has not been peer-reviewed.
Developers across major networks have been paying closer attention to the issue as sufficiently powerful quantum computers may eventually break the elliptic-curve cryptography used by Bitcoin, Ethereum and many other blockchains.

He added: 「We’re committed to keeping user assets secure, and TRON is set to be one of the few major blockchains that is quantum-resistant before Q-Day.」 The term “Q-Day” refers to the point when quantum computing becomes capable of breaking current security standards.
Proposal described in a technical paper
CoinDesk reported on July 28 that blockchain security company AmericanFortress had unveiled a cryptographic plan aimed at protecting crypto wallets from future quantum attacks without requiring users to move funds, rotate keys or change wallet addresses.
AmericanFortress said the design differs from most proposed post-quantum approaches because it lets existing wallet addresses remain unchanged while adding post-quantum protection.
The company published the proposal in a technical paper on the Cryptography ePrint Archive, although it had not yet been peer-reviewed.
Post-quantum cryptography draws wider industry attention
Developers have increasingly focused on post-quantum cryptography because sufficiently powerful quantum computers may eventually break the elliptic-curve cryptography that secures Bitcoin, Ethereum and many other blockchain networks.
Earlier this year, a Strategy-led consortium pledged $15 million to fund Bitcoin quantum security research. The Ethereum Foundation published a proposal for migrating accounts to quantum-resistant cryptography, and Algorand outlined plans to introduce quantum-resistant accounts by 2027.
