The announcement positions TRON ahead of several larger networks on timeline, though the real-world threat from quantum computing to current cryptographic systems remains largely theoretical for now. Ethereum Foundation developers launched a Post-Quantum Ethereum initiative in March, projecting that L1 protocol upgrades could be completed by 2029 — with full execution layer migration taking additional years beyond that. Solana has deployed post-quantum digital signatures on a testnet, and Google has set its own 2029 target for migrating to post-quantum cryptography. Whether TRON can actually deliver a mainnet rollout by Q3 2026 — significantly ahead of every other major player — will determine how credibly it can claim the first-mover title in quantum-resistant blockchain infrastructure.
