Block

A block is like a container that holds network transaction data. Each block connects to the previous one through a unique identifier called a hash. This creates a chain of blocks that cannot be changed. In Bittensor, each block creates one new TAO token.

Each block has several key parts that work together. The block stores events, which include all network actions like registrations, trades, and delegations. These events get grouped into larger units called extrinsics. Each block also records when it was created, helping track the network's timeline.

Blocks group into larger time periods called epochs. Every 360 blocks (about 72 minutes) make up one epoch. This timing matters because the network uses epochs to organize important actions like distributing rewards and updating validator weights .

Each block uses cryptography to stay secure. The hash system ensures that changing any information in a block would break its connection to later blocks. This makes the blockchain's history permanent and trustworthy.
