Blockchair is a blockchain search and analytics engine for Bitcoin, Ethereum, Ripple, Bitcoin Cash, Litecoin, Bitcoin SV, Stellar, Dash, Dogecoin and Groestlcoin or you can also say it's an engine that consists of blockchain explorers on steroids. You can filter and sort blocks, transactions, and their content by a variety of different criteria, as well as perform full-text search over the blockchains.
We aim to become Google for blockchains. Our next priority is to bring the ability to search over more other decentralized projects like IPFS and SWARM. In addition, we provide researchers with a way to batch export data from blockchains.
