TRON joins major chains preparing for future quantum threats
TRON founder Justin Sun has placed quantum security at the center of the network’s 2026 roadmap. The plan targets a testnet launch in Q2 and a mainnet rollout in Q3. The move gives TRON a clear position in the race for post-quantum blockchain protection.
TRON Targets Quantum-Resistant Security In 2026
Sun said TRON will begin testing quantum-resistant infrastructure in the second quarter of 2026. The network then plans to move the upgrade to mainnet in the third quarter. He linked the timeline to rising security needs across blockchain and AI systems.
The plan focuses on future risks from quantum computing and advanced decryption methods. Although current quantum machines cannot break most blockchain systems at scale, research continues across the industry. As a result, major networks now prepare for stronger cryptographic standards.
TRON aims to protect user funds before quantum threats become practical. Sun framed the upgrade as a key step for blockchain security in the AI era. The network wants to build protection before stronger computing systems reach wider use.
AI Growth Raises New Security Questions
AI adoption continues to expand across finance, data systems, and digital asset platforms. However, faster AI development also increases attention on long-term security risks. Sun said blockchain builders must address both AI benefits and new technical threats.
Quantum computing remains one of the main concerns in this discussion. Future quantum systems could challenge current cryptographic tools used by blockchains. Post-quantum security has become a growing topic for major crypto developers.
TRON’s roadmap places this issue inside its broader network strategy. The planned testnet will allow developers to assess the new security model before mainnet release. The Q3 target gives TRON a defined timeline for public deployment.
Other Networks Move Toward Post-Quantum Plans
TRON’s announcement comes as other blockchain groups study similar upgrades. Ethereum Foundation developers launched a Post-Quantum Ethereum site in March. Their roadmap points to some Layer 1 protocol upgrades by 2029.
Ethereum’s wider execution-layer migration may take longer because it needs deeper changes. Solana Foundation developers have tested post-quantum digital signatures on a testnet. These steps show that major chains now treat quantum readiness as a long-term priority.
Outside blockchain networks, Coinbase and Google have also moved into quantum security planning. Coinbase CEO Brian Armstrong announced an advisory board in January 2026 for blockchain and quantum risks. Google also set a 2029 target for its post-quantum cryptography migration.
