What is a 'block' in Avalanche compared to a 'commit'?

• A. A block is a new set of transactions; a commit is the finalization of that block under Avalanche consensus.
• B. A block stores only smart contract deployments; a commit stores only token transfers.
• C. A block is a user interface; a commit is a server process.
• D. A block is the same as a commit; they're interchangeable terms.

Answer: (A)

In Avalanche, a block is simply a batch of transactions that is proposed to be added to the ledger. The commit is the moment the consensus process has reached enough agreement to finalize that block, making its transactions part of the official chain and effectively immutable. So you can think of a block as the container of actions you want to record, and a commit as the act of the network agreeing that those actions are finalized and permanent.

Blocks aren’t limited to any specific type of transaction (deployments, transfers, or otherwise)—they can include a mix of transactions. A commit isn’t a separate data store or a server process; it’s the finalization step where the network confirms the block.
