Cryptocurrency Transaction Processing

Abstract

In a cryptocurrency network such as Bitcoin or Helium, the fundamental unit of interaction is a transaction where value is transferred from one entity to another. In this type of network, the blockchain is an immutable, distributed ledger of all of the transactions that have transpired on the network. Value is transferred from one public address to another public address. We can examine and enumerate all of the transactions associated with a public address by scanning the entire blockchain for transactions that involve this address. In fact, if we scan the blockchain forward from the genesis block, then the last transaction involving this address also provides the cryptocurrency balance which is associated with this address.
