  The block number is a fundamental aspect of Ethereum's security infrastructure. It acts as a reference point for the order and validity of transactions within the blockchain. By including the block number in transaction records, Ethereum ensures that each transaction is linked to a specific block, creating a chronological and immutable record. This prevents any attempts to alter past transactions or manipulate the transaction history. The block number also plays a crucial role in preventing double-spending, as each transaction is validated and confirmed within a specific block. Therefore, the block number is a key component in maintaining the security and trustworthiness of Ethereum transactions.
