TRON’s quantum plan could leave some wallets able to pay but unable to replace their keys

TRON’s draft quantum-signature design could leave some migrated accounts unable to replace their keys after network governance disables the signing scheme they depend on. Some of those accounts could still make payments through a separate permission.The design includes a possible recovery route through a second quantum-resistant signature scheme. To use it, holders would need the surviving keys to meet the account’s existing owner threshold, the level of authority required to change permissions. A backup key authorized only for payments would leave that repair power out of reach.That is the practical question behind Justin Sun’s quantum push. On Aug. 8, 2026, @justinsuntron said his goal was for TRON to become the first quantum-resistant blockchain network and referred to testing on the Nile test network. That dated statement of ambition provides the backdrop to a migration design whose governance switches can later withdraw approval for a signing scheme.As of Sept. 12, TIP-899 remains labeled Draft. Nile’s June 30 software release included implementations of Falcon-based FN-DSA-512 and ML-DSA-44, each subject to its own activation setting. Each implementation still needs its own g...
