Crypto Transaction

A crypto transaction is a digital instruction submitted to a blockchain network, usually to send cryptocurrency from one address to another. It is authorized with the sender’s private key, which creates a signature proving permission without revealing the key itself. The transaction typically includes the recipient address, amount, network fee, and other data needed by the blockchain to process it.

Crypto transactions matter because they are the basic way blockchains record activity. Once broadcast, the transaction is checked by the network, grouped into a block or similar record, and becomes difficult or impossible to change after confirmation. For example, sending bitcoin to a friend is like sending a bank transfer, but instead of a bank updating a private ledger, many network participants verify and store the record on a shared ledger.
