From beginner to advanced — master exchanges, wallets and blockchain essentials
Who runs Bitcoin? No single company or founder controls it. Bitcoin operates through nodes, miners, developers, and users following shared rules.
A bitcoin node runs the network’s rules, checks transactions and blocks, and helps keep the shared ledger accurate without a central server.
How many Bitcoin nodes are there? There is no single fixed count because public, hidden, and differently measured nodes are not the same thing.
