Encode x Wormhole Educate: Wormhole Queries

Wormhole Queries revolutionise blockchain interoperability by providing on-demand access to multi-chain data through the Wormhole Network. Wormhole Queries addresses the current isolation of blockchain data, likening it to the pre-API internet, and aims to build bridges between blockchains, allowing data to flow freely and securely. Ossie Amir from the Wormhole Foundation joins us for this workshop. If you want to build using Wormhole Queries check out the Beta information: https://wormhole.com/products/queries
