2 BACKGROUND
In this section, we introduce the key concepts that are used throughout our paper.
2.1 Blockchain
A blockchain is essentially a ledger of all transactional activity occurring on the network. The ledger is stored on the network using blocks: an object which stores a unique set of transactions, all of which are identifiable by their own unique ID. The information within blocks cannot be changed unless all of the blocks that came after it are also changed. As a result, it is common for information in a block to become immutable after a certain amount of blocks have been appended after it.
