As Substrate’s 1.0 release nears, many projects have already begun building on the blockchain framework. One such project that’s been working closely with the Parity development team is Polkascan, the first multi-chain block explorer.
Block explorers allow the public to query the blockchain for addresses, transactions (what we call “extrinsics” in Substrate), block details and all data stored in blockchains, so that users and developers can verify states, transactions and blocks on the network. Polkascan uses Substrate as the technological basis for making data on Substrate blockchains accessible and understandable.
