Most people will be unable to purchase an entire BTC because of its price, but you can buy portions of one BTC on these exchanges in fiat currency, such as U.S. dollars. Bitcoin uses the SHA-256 hashing algorithm to encrypt (hash) the data stored in the blocks on the blockchain. Simply put, transaction data stored in a block is encrypted into a 256-bit (64-digit) hexadecimal number. That number contains all the transaction data and information linked to the blocks before that block. A blockchain is a distributed ledger, a shared database of information that is chained together via cryptographic techniques. “Distributed” means that it is stored on many computers rather than a centralized server location, as is typical of most data storage.
