When a node successfully solves a puzzle, it creates a new block.\n2. Once a node creates a new block, it broadcasts the block to the entire  blockchain network. Upon receiving the new block, other nodes verify it to ensure that the transactions inside are valid and comply with the rules of the blockchain.\n3.
