Bypassing financial institutions is a key part of the Bitcoin promise. In the decentralization advocates mind, financial institutions are perfect examples of centralized points of failure. However, to average users of financial systems, which all of us are, bypassing financial institutions can mean significant savings in fees. When Alice wants to send Bob some bitcoin, all she needs is an internet connection and she’ll be able to broadcast her transaction to the Bitcoin blockchain – the ledger of all Bitcoin transactions.
