Understanding Block and Transaction Logs of Permissionless Blockchain Networks

Understanding Block and Transaction Logs of Permissionless Blockchain Networks

Public blockchain records are widely studied in various aspects such as cryptocurrency abuse, anti-money-laundering, and monetary flow of businesses. However, the final blockchain records, usually available from block explorer services or querying locally stored data of blockchain nodes, do not prov...
