Blockchain technology involves the use of a digital distributed ledger in which transactions are recorded chronologically and publicly. A blockchain can be used to store digital assets and record related transactions. The blockchain consists of a continuously growing list of records, called blocks, which are linked and secured using cryptography (i.e., codes that can't be read without a key). The goal of blockchain is to remove a centralized server or intermediary so that a decentralized network of computers can share and retain identical, cryptographically secured records.
