Free-riding node identification for blockchain

摘要

An example operation may include one or more of receiving system calls captured from a plurality of peer nodes of a blockchain that occurred within a predetermined period of time, determining a subset of system calls among the received system calls that correspond to a blockchain process performed during the predetermined period of time, detecting a free-riding peer node from among the plurality of peer nodes based on the identified subset of system calls with respect to system calls of the free-riding peer node within the predetermined period of time, and storing an indicator of the free-riding peer node.
