# Blocks Blocks on Keeta Network are the fundamental mechanism by which the [ledger](/components/ledger.md) is updated. Each block contains an ordered set of operations which are performed by a given [account](/components/accounts.md). Each block can hold multiple operations from the same account, and blocks can vary in size. Structure Blocks are encoded in ASN.1 DER, which enables them to be extensible in the future. The blocks’ size is dynamic, so it can be as large as the representatives will accept. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
