Block Explorer

A block explorer is an online tool for exploring the blockchain of a cryptocurrency, where you can watch and follow, live, all the transactions happening on the blockchain.

Depending on the type of blockchain, block explorers can also serve as a general information hub. For instance, there are thousands of ERC-20 tokens running on top of the Ethereum blockchain, and users can find data about them by checking their smart contracts on Etherscan or other Ethereum block explorer.
