Sending money through a banking app and sending bitcoin look almost the same. Underneath, one relies on banks, payment rails, clearing and settlement; the other on nodes, miners and a shared blockchain. Here's how each really works.
A valid Bitcoin transaction still has to be written into a block. Here's how miners build candidate blocks, search for a valid Proof of Work, and how nodes decide which block joins the blockchain.
Bitcoin has no bank checking who's authorized to spend what. Instead, a wallet signs every transaction with a private key, and nodes across the network verify that signature using nothing but math. Here's exactly how that works, step by step.
