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.
