The primary function of a blockchain explorer is to enable users to view blockchain transactions. Blockchain explorers are web-based tools that provide a user-friendly interface for accessing and analyzing data on a blockchain. They allow individuals to look up specific transactions, view wallet balances, track the history of addresses, and access block information.

By using a blockchain explorer, users can gain transparency into the blockchain's operation, as it records every transaction that occurs within that network. This transparency helps build trust in the system since anyone can verify that transactions are valid and have been confirmed by the network's miners.

The other functions described in the other options do not align with the primary capabilities of a blockchain explorer. Creating new blockchain nodes involves a more technical process of setting up servers that connect to the blockchain network. Mining cryptocurrency refers to the process by which transactions are verified and added to the blockchain, requiring specific hardware and software setups. Facilitating smart contract execution involves a distinct set of operations related to programmable scripts on blockchains that support them, like Ethereum, rather than the basic transaction visibility provided by blockchain explorers. Thus, the focus on viewing transactions distinctly defines the integral role of a blockchain explorer.
