That's a fancy way of saying that there's no central hub where transaction data is stored. A new block is only considered valid if it has information about all previous chain links, and a copy of the chain is only valid if it starts with genesis block. Recently, we broke down what cryptocurrencies are in the easiest way possible. This transaction is composed of three pieces of information: Which "coins" to spend, the recipient, and a signature. what are bitcoin "confirmations"?
