Blockchain Explorer

The blockchain ledger is immutable meaning, that all past transactions cannot be changed or altered in any way once they are written into the ledger. The consensus mechanism ensures that data is safe from manipulation or tampering and that transactions will remain reliable.

From this perspective, blockchain explorers are an essential tool in the world of cryptocurrency and blockchains. They provide an easy-to-use interface that allows users to explore, monitor, and analyze transactions. Blockchain explorers also allow users to view balances, transactions’ history, and other information, therefore providing a comprehensive view of the network. Everything on Ethereum is publically available and can be retrieved whenever needed.

A lot of blockchain explorers exist; they typically offer a web interface giving real-time visibility of on-chain activities and data. The most popular one for Ethereum is the Etherscan explorer.
