The key components of a block in a blockchain are:

1. Block Number: The position of the block within the blockchain.
2. Nonce: A random number used in the mining process to create a hash value that meets certain criteria.
3. Previous Block Hash: The cryptographic hash of the previous block in the blockchain.
4. Timestamp: The time when the block was created and added to the blockchain.
5. Transactions Data: The actual data that is being stored in the block, such as transactions or smart contract information.
6. Merkle Root: The hash of all the transactions in the block, used to ensure data integrity.
7. Difficulty Target: The level of difficulty required to mine a new block in the blockchain.
8. Block Size: The amount of data that can be stored in the block.
9. Miner's Reward: The incentive given to the miner who successfully mines the block.
10. Block Header: The metadata about the block, including the previous block hash, Merkle Root, timestamp, and nonce.
