Initiating a Transaction
A transaction begins when someone wants to transfer digital assets. This involves specifying the recipient’s address and the amount to be sent. The transaction is then digitally signed using the sender’s private key.
Verification and Validation
Once initiated, the transaction is broadcast to the blockchain network. Nodes, or computers, within the network verify the transaction’s validity. This includes checking the sender’s balance and ensuring the digital signature is correct.
Adding to a Block
Valid transactions are grouped together into a block. This block includes a timestamp and a hash of the previous block, creating a chain.
Consensus Mechanism
To add a new block to the blockchain, a consensus mechanism is used. Proof of Work and Proof of Stake are common examples. This ensures agreement among network participants about the block’s content and order.
Confirmation and Finality
Once a block is added to the blockchain, the transactions within it are considered confirmed. As more blocks are added, the transactions become increasingly immutable and secure. The transaction is now complete.
