Batch Transactions
How batch transactions group multiple Bittensor chain actions while preserving signer, fee, and failure boundaries.
-
Block
How a block groups Bittensor transactions into an ordered blockchain record.
-
Chain Reads
How chain reads describe looking at public Bittensor chain state without asking Subtensor to record a new action.
-
Extrinsics
Extrinsics are Bittensor chain actions that ask the Subtensor runtime to process a state-changing operation.
-
Mempool
How the Bittensor mempool holds pending transactions before block inclusion.
-
Mempool Visibility
How pending transaction visibility creates MEV risk in Bittensor before block inclusion.
-
MEV (Maximal Extractable Value)
How MEV names the value extractable by manipulating transaction ordering in Bittensor's mempool context.
-
MEV Shield
How Bittensor's MEV Shield hides sensitive transaction details before block inclusion to reduce mempool-based MEV risk.
-
Rate Limits
How Bittensor rate limits use block-based cooldowns to pace repeated chain actions.
-
Replay Attack
How a replay attack reuses a valid signed message, and how Bittensor's increasing, freshness-checked nonces keep a reused message from being accepted again.
-
Sandwich Attack
How a sandwich attack names a transaction ordering exploit that wraps a target transaction between two adversarial ones in Bittensor.
-
Transaction Fees
How Bittensor distinguishes base chain transaction fees from swap fees tied to stake-related actions.
