Learn About Blockchain [Part2]
What is Blockchain?
☞Blockchain is a type of shared database that differs from a typical database in the way it stores information; blockchains store data in blocks linked together via cryptography.
☞Different types of information can be stored on a blockchain, but the most common use for transactions has been as a ledger.
☞In Bitcoin’s case, blockchain is decentralized so that no single person or group has control—instead, all users collectively retain control.
☞Decentralized blockchains are immutable, which means that the data entered is irreversible. For Bitcoin, transactions are permanently recorded and viewable to anyone.
