    • detail - the detailed name of the entity (this is where a cryptocurrency address would be stored
    • names - a list of names given to the entity (comma separated)
    • start0 - start from date
    • start1 - start to date
    • end0 - end from date
    • end1 - end to date
• check_address.py - a script to check whether SDN "details" are valid cryptocurrency addresses on a variety of different blockchains. Data saved to data/tagged_addresses.csv
• get_contract_logs.py - generic script to get all the events from a target Ethereum contract (requires a local Ethereum node to run)
• get_tornado_deploy_blocks.py - gets the block heights where the Tornado Cash contracts in the SDN list were deployed. Data saved to data/tornado_deploys.csv
• get_tornado_logs.py - gets all the events from all the Tornado Cash contracts on the SDN list and stores them in the data/ folder
• utils.py - helper script to get contract data from Etherscan
• blockchain_stats.py - Displays some basic summary statistics about how many entries on the SDN list correspond to cryptocurrency addresses
