Definition
A transaction in blockchain is a recorded action that changes data on the network, usually involving the transfer of digital value or updating account balances. It is a basic unit of information that is created by a user, broadcast to the network, and, once accepted into a block, becomes part of the permanent blockchain record.
In Simple Terms
A transaction is a digital record that says who is sending something and who is receiving it on a blockchain. It is written into the blockchain so everyone can see and agree on the change. Each transaction is a small piece of information that updates the shared ledger.
Context and Usage
The term “transaction” appears in discussions about sending and receiving cryptocurrency, tracking balances, and viewing blockchain activity. It is central to how value and data are represented on systems like public blockchains and Layer 1 networks. Wallet interfaces, block explorers, and exchange platforms commonly display transaction details as part of normal blockchain activity.
