Blockchain transactions involve the transfer of data or digital assets within a blockchain network. When a network participant sends a transaction, it is recorded in a new block and added to the chain of blocks. In blockchain, transactions can be associated with financial transfers, smart contracts, digital asset exchanges, and other operations.
Each blockchain transaction contains information about the sender, recipient, amount, and other relevant data. Additionally, each transaction is digitally signed by the sender to ensure its authenticity and integrity.
In the blockchain, transactions are processed and verified by network nodes. Nodes verify if the sender has sufficient funds to carry out the transaction and confirm its correctness. The transaction is then added to a block and propagated throughout the network for other nodes to verify and add to their copy of the blockchain.
Transactions in the blockchain are typically transparent and immutable. They can be viewed by all network participants, and once added to the blockchain, they cannot be changed or removed without the consensus of the majority of network nodes.
