A block explorer is a blockchain search engine that allows you to search for a particular piece of information on the blockchain. The activities carried out on crypto blockchains are known as transactions, which occur when cryptocurrencies are sent to and from wallet addresses. Each transaction is recorded onto a digital ledger, known as a blockchain. Blocks on the blockchain are collections of transactions that were processed and approved by a group of third-parties known as validators.
A block explorer is an online tool to view all transactions that have taken place on the blockchain, the transaction growth, and the activity on blockchain addresses, among other useful information. You can think of it as a window into the blockchain world, giving you the opportunity to observe what’s happening on it.

Anytime you buy, sell, send, or receive MobileCoin, you can utilize the block explorer to check on the status of your transactions. Once you initiate a transaction, you should receive an automatically-generated transaction hash and can use the hash to look up details of the payment and whether it was successful.
