Blockchain Transaction
Also known as: On-Chain Operation, Crypto Transaction, Signed Blockchain Message
A signed, verifiable action on a blockchain that alters the network state, such as sending tokens or calling a contract.
A blockchain transaction is a digitally signed message that changes the state of a distributed ledger. Transactions can transfer tokens, call smart contracts, mint NFTs, or perform staking operations. Each transaction includes data such as sender, recipient, gas fees, and a unique hash. Once validated by the network, it is permanently recorded in a block. Transactions must follow protocol-specific rules and require fees to deter spam and compensate validators or miners. Blockchain explorers allow anyone to view transaction status, fees, and details publicly.
