Admin Freeze Window
How the admin freeze window blocks subnet owner operations during the final blocks of each epoch so hyperparameters cannot change just before validators submit weights.
-
Bittensor CLI: Permissions Guide
How BTCLI permissions map Bittensor command-line actions to permissionless reads, hotkey authority, coldkey authority, balances, validator permits, and Senate roles.
-
Bittensor Wallet
How a Bittensor wallet names the identity and ownership container for coldkeys, hotkeys, and stake in Bittensor operations.
-
Bittensor Wallets
What a Bittensor wallet is, what it stores, and how it is used to prove identity and sign transactions on the network.
-
Coldkey and Hotkey Workstation Security
How Bittensor separates permissionless devices, hotkey servers, proxy coldkeys, and primary coldkey custody when thinking about workstation risk.
-
Coldkey Swap
How a coldkey swap migrates a Bittensor wallet's entire on-chain identity to a new coldkey through a staged, disputable on-chain process.
-
Coldkey Swap Announcement Delay
How the coldkey swap announcement delay sets the mandatory waiting window in blocks between announcing a coldkey swap and when that swap can finalize.
-
Coldkeys (Bittensor)
The security-critical key that controls TAO and stake; used for financial transactions like stake, unstake, and transfers.
-
EdDSA Cryptographic Keypairs
How EdDSA cryptographic keypairs fit Bittensor wallet-key terminology.
-
Encrypting the Hotkey
How encrypting a Bittensor hotkey protects local hotkey material while preserving the hotkey's operational role.
-
External Wallet
How an external wallet refers to wallet software or custody outside the local Bittensor wallet path.
-
Hotkey Swap
How a hotkey swap moves Bittensor subnet participation from one hotkey to another hotkey owned by the same coldkey.
-
Hotkey Swap On Subnet Interval
How the hotkey swap on subnet interval sets the per-subnet cooldown a hotkey swap must respect, the longer of the two rate limits that gate swapping a hotkey.
-
Ledger Hardware Wallet
How a Ledger hardware wallet fits into Bittensor coldkey custody, wallet-app signing, staking, transfers, proxy setup, and address verification.
-
Local Wallet
How a local wallet refers to Bittensor wallet files kept on a user's machine.
-
Max UIDs Trimming Rate Limit
How the UID trimming rate limit caps how often a subnet owner can trim UIDs, locking the subnet's UID count for roughly 30 days after each trim.
-
Mnemonic
How a mnemonic represents a wallet recovery phrase in Bittensor key management.
-
Multisig Wallets
How a Bittensor multisig wallet distributes control of a coldkey across several signatories, requiring a threshold of approvals before an action can go ahead.
-
NaCl Format
How NaCl Format fits Bittensor wallet-file security terminology.
-
Polkadot Vault
How Polkadot Vault fits into Bittensor coldkey custody, air-gapped signing, QR transaction transport, Subtensor extrinsic support, and proxy-oriented key operations.
-
Private Key
How private key names the protected side of a Bittensor cryptographic key pair used for authorization.
-
Proxy Wallets
Proxy wallets let one Bittensor account perform limited actions for another, helping reduce how often a high-value wallet must be used directly.
-
Public Key
How a public key fits Bittensor wallet-key terminology as the shareable side of a cryptographic keypair.
-
Pure Proxies
Pure proxies are keyless Bittensor accounts used as stable stand-ins, especially in multisig designs where the people behind a shared wallet may change.
-
Regenerating a Key
How regenerating a key relates to recovering Bittensor wallet key material.
-
Seed Phrase
How a seed phrase names the human-readable recovery words that can restore Bittensor wallet key access.
-
Signatory
How a signatory is one participant in a multisig wallet who can propose or approve actions under the wallet's threshold rule.
-
Tx Rate Limit
How the tx rate limit chain parameter sets the general transaction rate limit in blocks, the cooldown that currently governs hotkey swaps and raises TxRateLimitExceeded when breached.
-
Wallet Applications
How wallet applications provide the software layer for viewing Bittensor wallet state, preparing transactions, and connecting custody devices without being the wallet identity itself.
-
Wallet Location
How wallet location describes where Bittensor wallet files are stored on a user's machine.
-
Wallets, Coldkeys, and Hotkeys
Understanding Bittensor wallets and the roles of coldkeys and hotkeys for security, identity, and operations.
