Every transaction made on a blockchain is recorded in the form of “blocks” that are connected, creating an unbroken chain of blocks. This is why it is referred to as a “blockchain.”
how does blockchain work?
blockchain transactions
When someone makes a transaction, such as sending a cryptocurrency like Bitcoin, information about this transaction is created.
Verification
The transaction is then sent to a network of computers called “nodes.” These nodes work to verify the legitimacy of the transaction, ensuring that the sender has the currency to send and that the transaction is not duplicated.

Block Creation
Once transactions are verified, they are combined with other transactions in a block. This block is then tethered to previous blocks in the blockchain, creating an unbroken link between each block.
Consensus
For new blocks to be added to the blockchain, the network of nodes must reach “consensus.” This means that most of the nodes on the network must agree that the new block is valid. This consensus ensures that it is impossible to forge or alter transactions that have already been entered into the blockchain.
Addition to the Blockchain
Once a new block is accepted, it is added to the blockchain, and the transaction is considered complete.
