It works as data storage space of collected data from different nodes across the peer-to-peer setup, and every participated node holds a carbon copy of identical data. Blockchain is a decentralized structure, so there are no federal supervisors; hence the data reliability is maintained with the consensus models to ensure the data duplications’ truthfulness on every dependent node. Several nodes must execute through a consensus model to accomplish an agreement to commit to the order of transactions. In particular, a distributed ledger is an appended-only data storeroom, plus the transaction modernizes actions traced at every entity node in an ungraceful approach.
