Blockchain technology started as the basis for Bitcoin that allowed the cryptocurrency to operate but now it has spread to various other industries as well like healthcare. Blockchain systems are actually decentralised distributed ledger systems created by app Development Company that record transactions on blocks that are linked together and store them on an encrypted digital ledger. Since the entire blockchain system is decentralised it has no one central administrator which imparts the system extreme security because records are spread across a network of replicated databases that are always in sync. All entries in a blockchain system are time and date stamped that can only be accessed and updated by authorised users.
