Block
Protocol
Batch of transactions appended to the blockchain.
A block is a bundle of transactions and state updates. It links to the prior block with a hash, which creates the chain. Valid blocks extend the chain and help the network agree on the current state. Explorers show the details so you can inspect what happened.

It depends on the network. Some target fixed times, others are variable. Check your chain’s documentation.Can blocks be reorganized?
Yes. Short reorgs can happen when two tips compete. Finality rules determine when a block is considered durable.
