Blockchain

class blocksci.Blockchain(loc)

Class representing the blockchain. This class is contructed by passing it a string representing a file path to your BlockSci data files generated by blocksci_parser

__getitem__(*args, **kwargs)

Overloaded function.

1. __getitem__(self: blocksci.blocksci_interface.Blockchain, arg0: int) -> blocksci::Block
