What is typically visible through a blockchain explorer?

The choice highlighting transaction history and block details accurately reflects the purpose of a blockchain explorer. Blockchain explorers serve as tools that allow users to view and analyze real-time information about transactions occurring on the blockchain. Through these explorers, individuals can access detailed data about specific transactions, including transaction IDs, amounts, timestamps, and the addresses involved. Additionally, explorers provide insights into blocks, such as the block height, timestamps of when the block was mined, and the miner responsible for securing that block.

This option is fundamentally about transparency, which is a core characteristic of blockchain technology. The decentralized nature of blockchains means that while transaction details are visible, identifying specific user identities is not directly possible; transactions are linked to cryptographic addresses rather than personal information. This maintains privacy while still allowing for verification of whether transactions have occurred, reinforcing the visible and traceable aspect of blockchain technology.

On the other hand, options discussing real-time trading prices, user identity details, and private keys are not accurate representations of what a blockchain explorer typically provides. Real-time trading prices are generally found on exchange platforms, while user identities remain pseudonymous on the blockchain, and private keys are confidential information meant to secure access to cryptocurrency wallets, contrasting sharply with the openness of transaction details available via explorers
