On an elementary level, blockchain is a distributed database that maintains a perpetually growing list of records called blocks. It works like every block has a timestamp with a link to the previous block. It has been designed in such a way that data in the block cannot be altered retroactively, which means once recorded it cannot undergo modifications. Every system in the entire centralized database has its own firewalls and guards. At the time of a transaction, both the buyer and seller broadcast the transactions. In this process, a new block is added to the chain while all other computers in the chain update their personal records or ledger.
