Bitquery Explorer is constructed by using the blockchain data building blocks, Bitquery Widgets.
Bitquery explorer is a multi-blockchain explorer that shows analytics for more than 30 blockchains. Our explorer is made out of embeddable widgets and supported by GraphQL APIs.
We use a multi-dimensional analytical database (OLAP), which gives us the capability to aggregate data to create complex blockchain analytics. And our explorer helps in visualizing this complex data using simple charts and graphs.
