# OlaOS OlaOS is Ola's node implementation repositor. Users can submit transactions to Ola through the JSON-RPC interface, and all transactions submitted by users will be persisted to the underlying database. The mempool fetcher component is responsible for synchronizing received transactions to the mempool, where transactions are waiting to be executed by the sequencer(via OlaVM) and packaged into blocks. This document will introduce the projects details of OlaOS from several aspects, and be updated as the project develops. --- # 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.
