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

Return the block of the given height

2. __getitem__(self: blocksci.blocksci_interface.Blockchain, arg0: slice) -> List[blocksci::Block]

Return a list of blocks with their heights in the given range

__iter__(self: blocksci.blocksci_interface.Blockchain) → iterator

Allows direct iteration over the blocks in the blockchain

__len__(self: blocksci.blocksci_interface.Blockchain) → int

Returns the total number of blocks in the blockchain

filter_blocks(filterFunc, start=None, end=None, cpu_count=8)

Return all blocks in range which match the given criteria

filter_txes(filterFunc, start=None, end=None, cpu_count=8)

Return all transactions in range which match the given criteria

heights_to_dates(df)

map_blocks(blockFunc, start=None, end=None, cpu_count=8)

Runs the given function over each block in range and returns a list of the results

mapreduce_block_ranges(chain, mapFunc, reduceFunc, init, start=None, end=None, cpu_count=8)

Initialized multithreaded map reduce function over a stream of block ranges

mapreduce_blocks(chain, mapFunc, reduceFunc, init, start=None, end=None, cpu_count=8)
