In this post, you learn how to use Amazon Managed Blockchain Query and Amazon Managed Blockchain Access, along with a handful of other AWS services to deploy a React frontend application that displays digital asset data from the Bitcoin and Ethereum blockchains in a matter of minutes. This drastically reduces the complexity and number of AWS services required to accomplish the same functionality, and offers predictable costs based on usage of a set of APIs for blockchain data queries and JSON-RPC requests to public blockchains. With the launch of Amazon Managed Blockchain Access and Amazon Managed Blockchain Query, customers building digital asset applications and user experiences (UX) can trade the undifferentiated heavy lifting involved in blockchain node and data operations for on-demand, pay-as-you go services that serve the same requirements. The same case can be made for operating a fleet of public blockchain nodes to serve request traffic to send transactions to the Bitcoin blockchain, for example, which requires ongoing operating costs that can be shed in favor of API-driven solutions that bill only for requests made to a given blockchain. Building these features in-house diverts resources from use-case specific functionality that differentiate a product from its competitors. However, these indexing and ETL resources are not heavily differentiated. To build such user interfaces for end users to view their digital asset balances on one or more public blockchains, one must invest in resource-intensive blockchain indexing infrastructure and complex extract transform and load (ETL) pipelines to serve data to frontend applications. This data includes but is not limited to current and historical asset balances, historical transaction lists, transaction events, and more for each blockchain network on which assets are traded and owned. From startups like digital asset wallet providers to enterprises like banks, companies are launching digital asset products that provide end users the ability to buy, sell, exchange and monitor their digital assets, such as cryptocurrency. Whether the end user is an institutional investor or a retail investor / enthusiast, all of these digital asset products require accessible user-experiences that display pertinent data related to a user’s digital assets.
