REST API interface to blockchain networks
Download as PPTX, PDF•0 likes•154 views
This document discusses connecting applications to blockchain networks through REST interfaces. It presents two common options - using a native API that directly connects to a specific blockchain network like Bitcoin, or using an abstraction layer that provides a standardized REST API to interact with multiple blockchain networks. The document then demonstrates how to use a REST API to interact with the Ethereum blockchain through practical exercises using Postman to read data, transfer currency, and check balances and blocks.
