What is the predefined business logic within a blockchain?
A blockchain is a distributed database that allows for secure, transparent and tamper-proof record keeping. Each block in the chain contains a cryptographic hash of the previous block, a timestamp, and transaction data. The transaction data can be anything, but is most commonly financial data. The predefined business logic within a blockchain is the set of rules that determine how the data in the blockchain can be accessed and manipulated. This business logic is encoded in the form of smart contracts. Smart contracts are self-executing contracts that live on the blockchain and can enforce the rules of the business logic.
