Distributing the Data Store among Peers

The last step turned the blockchain data structure into an immutable, append-only data store that can serve as a tamper-resistant ledger for transaction data. Having a single, immutable, append-only history of transaction data in isolation may be of limited value for our goal of clarifying ownership based on a group of computers that serve as witnesses to ownership-related events. Hence, this step focuses on establishing a purely distributed peer-to-peer system that shares transaction information.
