Justin Sun sees Tron quantum-resistant shift in 2026; Ethereum, Solana also respond

Tron plans to shift to a quantum-resistant network in 2026, with a testnet launch in the second quarter and a mainnet rollout in the third, founder Justin Sun said. Sun called it the world’s first quantum-resistant network and cited quantum computing decryption as a key risk. Other players are also preparing: Ethereum has outlined post-quantum resources and a layer-1 upgrade plan through 2029, while Solana has deployed post-quantum signatures on its testnet.
