![]() Each Transaction is from one Address and may be to another one. ![]() The Transactions are where much of the action is. Strictly speaking Token and Contract aren’t necessary but they certainly are convenient for helping humans make sense of what’s going on.Įach Block will CONTAIN zero or more Transactions. Token and Contract are subtypes of Address. To create a knowledge graph of blockchain data we need to define only a few different types of nodes: Block, Transaction, Address, Token, Contract, and LogEvent. If you would rather spend your time doing data science instead of blockchain development, this is a serious barrier to entry. What if you wanted to find all such transactions? Today you would have to download the whole chain and interact with the ABI. This transaction describes a swap between bitcoin (technically WRBTC) and the stable coin Tether. Its also difficult to get a summary of the data. This is clunky and much of the data is not human-readable. ![]() If you want to understand the activity on the protocol, and the developers don’t happen to provide the answer on the official app, you have to dig into the block data. Both are difficult and unintuitive, particularly for developers that may be new to the space. After reading the documentation you have to read the source code of the smart contracts, or explore the raw block-level data. Blockchain and DeFi are advancing quickly, and the pace of progress is faster than the advances in tooling.
