What is a blockchain?
A blockchain is a digital, public ledger that records online transactions. Blockchain is the core technology for cryptocurrencies like bitcoin.
A blockchain ensures the integrity of a cryptocurrency by encrypting, validating, and permanently recording transactions.
A blockchain is similar to a bank’s ledger, but open and accessible to everyone who utilizes the cryptocurrency.
