Abstract
Methods and systems are presented for tracking activities that occur off of a first layer blockchain in in a second layer network built on the first layer blockchain. In one embodiment, a computer system determines that a transfer of cryptocurrency from a first node to a second node has transpired in the second layer network based on querying channel capacities in the second layer network. The computer system determines a first public address for the first node based on information associated with a first channel that connects the computer system and the first node in the second layer network, and determines a second public address for the second node based on information associated with a second channel that connects the computer system and the second node in the second layer network. The first public address and the second public address are used to monitor activity in the first layer blockchain.
