# Blockchain Actions Like other blockchains, IoTeX was bootstrapped from an initial ("genesis") state, which is then altered over time through transactions, or "Actions" as they are called in IoTeX. An action is fundamentally a packet of data, signed by a blockchain account, that instructs the blockchain to make a specific change to the distributed ledger. The action can be sent to any blockchain node acting as a gateway, which in turn broadcasts it to the entire network of nodes for verification. Once verified, it gets applied and stored permanently in the ledger. In IoTeX, there are different types of Actions depending on the type of operation required: * Transfer Action * Execution Action * Governance Actions Find the structure for all IoTeX Actions in the protobuf definition on GitHub: {% embed url="" %} --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.iotex.io/blockchain/learn-iotex/core-concepts/blockchain-actions.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
