Exploring a Multi-Chain Universe with Polkascan
from Relay Chain Hosted by Parity Technologies
In our fifth episode, Nicole Zhu and Joe Petrowski talk to Emiel Sebastiaan, WEB3SCAN CEO, about Polkascan, an open-source block explorer that allows any Substrate-based blockchain project to have a block explorer. They discuss the Polkadot multi-chain explorer, how a DAO could fund block explorer services, Polkascan vs. Polkadot UI, and the nitty-gritty of how one actually goes about extracting data from a blockchain.
