 * Amazon Managed Blockchain (AMB) Query provides you with convenient access to multi-blockchain network data, which
 * makes it easier for you to extract contextual data related to blockchain activity. You can use AMB Query to read data
 * from public blockchain networks, such as Bitcoin Mainnet and Ethereum Mainnet. You can also get information such as
 * the current and historical balances of addresses, or you can get a list of blockchain transactions for a given time
 * period. Additionally, you can get details of a given transaction, such as transaction events, which you can further
 * analyze or use in business logic for your applications.
