<p><strong>TRON founder Justin Sun has set a 2026 timeline for the network’s move toward quantum-resistant security.&nbsp;</strong></p><div id="cn-block-summary-block_5078ea621e2cb4c5dd850d3785c9894b" class="cn-block-summary"><div class="cn-block-summary__nav tabs"><span class="tabs__item is-selected">Summary</span></div><div class="cn-block-summary__content"><ul class="wp-block-list"><li>TRON plans to launch its quantum-resistant testnet in Q2 2026 before a Q3 mainnet rollout.</li><li>Justin Sun said quantum security will become a key demand as AI and computing risks grow.</li><li>Ethereum, Solana, Coinbase and Google are also working on post-quantum security plans this year.</li></ul></div></div><p>The plan includes a testnet launch in Q2 2026. Sun said the mainnet rollout is planned for Q3 2026.

He said the technology may create new security concerns as AI systems become more advanced.</p><p>“As the founder of a major cryptocurrency, we should, while focusing on the benefits of AI applications, pay close attention to the risks brought by AI development, with quantum computing’s decryption being the most core key,” Sun said.</p><p>You might also like: <a href="https://crypto.news/south-koreas-kbank-trials-onchain-remittances-with-ripple-partnership/" rel="noopener noreferrer nofollow"> South Korea’s KBank trials onchain remittances with Ripple partnership </a></p><h2 class="wp-block-heading" id="strong-quantum-threat-remains-early-but-watched-strong"><strong>Quantum threat remains early but watched</strong></h2><p>Quantum computing does not yet pose a practical threat to most blockchain systems.
