Run Your Own Mirror Node

Overview

A Hedera Mirror Node is a node that receives pre-constructed files from the Hedera Mainnet. These pre-constructed files include transaction records and account balance files. Transaction records include information about a transaction, like the transaction ID, transaction hash, account, etc. The account balance files give you a snapshot of the balances for all accounts at a given timestamp.

In this tutorial, you will run your own Hedera Mirror Node. You will need to create either a Google Cloud Platform (GCP) or an Amazon Web Services (AWS) account if you do not have one already. The Hedera Mirror Node object storage bucket, where you will pull the account balance and transaction data from, is stored in GCP or AWS bucket and is configured for requester pays. This means the mirror node operator is responsible for the operational costs of reading and retrieving data from the GCP/AWS. A GCP/AWS account will provide the necessary billing information for requesting the data.
