Bittensor Launches Quantum-Resistant Wallet with Post-Quantum Signatures and Automatic Key Rotation

Odaily reports: The Opentensor Foundation announced that Bittensor has launched a quantum-resistant wallet, offering users post-quantum signatures and the option to automatically rotate signing keys. The wallet supports three post-quantum signature schemes: ML-DSA-65, Falcon-512, and Falcon-1024, with ML-DSA-65 having been standardized by the U.S. National Institute of Standards and Technology (NIST). The automatic key rotation feature switches the wallet to a new signing key after a user's signed transaction is recorded on-chain; the old key can no longer authorize transactions for that account, while the address, balance, and staking remain unchanged. The wallet supports both cold keys and hot keys, and can be used for TAO transfers, staking, and validator weight setting, as well as multisig and proxy accounts.
