The remainder of the world’s money exists as digital records in databases controlled by global commercial banks that manage deposits, savings, and money market accounts.

Although the complete blockchain is not needed all at once since it is possible to run in pruning mode. A command line-based daemon with a JSON-RPC interface, bitcoind, is bundled with Bitcoin Core.
