TRON founder Justin Sun has outlined a timeline for the network to transition toward quantum-resistant security, setting a 2026 schedule for a testnet launch followed by a mainnet rollout.
TRON plans to launch its quantum-resistant testnet in Q2 2026, with a Q3 2026 rollout for the quantum-resistant mainnet. Sun described the upgrade as part of TRON’s goal to become the “world’s first quantum-resistant network.”
Sun said quantum security is expected to become a key demand as AI and computing risks increase. He also argued that blockchain networks need to prepare for future risks associated with quantum computing, including potential new security concerns as AI systems become more advanced.
“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.
Sun characterized quantum computing as not yet posing a practical threat to most blockchain systems. However, he noted that developers across the crypto industry continue studying how future quantum machines could affect cryptographic protections.
He also said TRON user funds would remain secure as the network prepares for new computing risks.
TRON’s plan aligns with broader efforts by other crypto and technology groups to develop post-quantum security measures.
While quantum computing is not yet considered a practical threat for most blockchain systems, the industry’s focus on post-quantum security reflects preparations for future cryptographic challenges as computing capabilities evolve.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
