Tron will move to a quantum-resistant network in 2026.

BeInCrypto, a blockchain media outlet, reported on Sunday that Tron founder Justin Sun (저스틴 선) said Tron plans to run a quantum-resistant network on its testnet in the second quarter of 2026 and apply it to its mainnet in the third quarter.

Sun claimed the upgrade would make it the world’s first quantum-resistant network. In a post on X, formerly Twitter, he said people should see the benefits of using artificial intelligence while also paying attention to risks from AI advances. He pointed to quantum computing’s decryption capability as the most critical risk.

Tron sees quantum-security infrastructure as a prerequisite for the AI era. Sun said post-quantum security is the top priority demand because of decryption risk, and stressed that user funds on the network would remain safe even in an AI-centric environment.

It is still difficult to say quantum computing has reached a stage where it can effectively neutralise existing cryptographic systems. Still, major blockchain networks and technology companies have begun pre-emptive steps to prepare for future risks. Tron’s timetable disclosure came amid that trend.

Ethereum Foundation developers in March launched a website introducing overall resources for responding to post-quantum threats to Ethereum. Ethereum has presented a plan to complete layer-1 protocol upgrades by 2029, but sees a full transition of the execution layer as taking longer.

The Solana Foundation went a step further by deploying post-quantum digital signatures on its testnet. Efforts are also continuing off-chain. Brian Armstrong (브라이언 암스트롱), chief executive of Coinbase, announced in January 2026 the formation of an independent advisory committee dedicated to quantum computing and blockchain security. Google last month also set 2029 as its target date to transition to post-quantum cryptography.

Against that backdrop, Tron’s third-quarter 2026 mainnet rollout schedule is earlier than other networks. It remains to be seen whether the shift will proceed as planned. Whether Tron meets its timeline could also affect how urgently rival networks view the quantum computing threat this year.

The quantum-security race has moved beyond the experimental stage of a single project into a phase where multiple chains and companies pursue it in parallel. Tron moved to seize an early lead by presenting a relatively early timetable, and the market has turned its attention to whether the testnet launch and mainnet transition proceed as scheduled.
