Block explorer is an application that helps traders to view all the past and current transactions on the Blockchain. Enabling users to explore block details, Block Explorer ensures complete visibility to any transactions or any actions taken by the holders of a given cryptocurrency.
Fortunately, block explorer is also available for specific altcoins as well. You can access a plethora of block explorers online. Some of the most popular ones include Mempool, Blockstream, Bitaps, Bitupper Explorer, and Blockchain Info.
Block explorers allow users to access information on the block height, block rewards given, age of a particular block along with the identity of a user or pool of users who minted the block. Not to mention, anyone can view the transactional history as well as the status of a given transaction in the block.
