Now that you have understood the basic operations on the Covalent Network, you can start exploring which nodes to run.

Block Specimen Producer

The Block Specimen Producer securely extracts data from blockchains, creating what is known as Block Specimens - a bulk export method that ultimately leads to the generation of a canonical representation of a blockchain’s historical state.

Block Results Producer

The Block Results Producer re-executes or processes the Block Specimens further, producing enriched data outputs called Block Results, a comprehensive representation of block data returned from an RPC call to a blockchain node, with additional fields for in-depth analysis.
