Final answer:
When a new cryptocurrency transaction occurs, a new block contains a block header, transaction counter, and the transactions themselves, all vital for maintaining blockchain integrity.
Step-by-step explanation:
When a new transaction in cryptocurrency like Bitcoin takes place, a new block in the blockchain is created. This new block contains several values to ensure the integrity and continuity of the blockchain. The three primary values that would be generated for a new block are the block header, which includes important information like the version, the previous block hash, the merkle root, the timestamp, the difficulty target, and the nonce; the transaction counter, which signifies how many transactions are included in the block; and the transactions themselves, which is essentially a list of all transactions that the block is confirming. These elements work collectively to secure the blockchain and confirm new transactions in a decentralized manner.
