This week Anna chats with Ismail Khoffi from Celestia about how and why they’re focusing on building a data availability-first L1 blockchain. Ismail takes us through how data availability can be a problem, primarily with light clients and breaks down the components necessary to understanding the data availability problem such as state changes, the separation of consensus from execution and how Celestia aims to be a pluggable consensus layer.

This week, Anna and Tarun chat with MP, Trent and Sam from JPG about this on-chain NFT curation protocol. They walk through what the JPG team wanted out of this decentralized curation protocol and how to bring in voices that aren't always heard in the traditional art world. They also explore the idea of rethinking the mechanism of curation, indexing and permissionless access in order to bring a crypto native approach to NFT art culture. Lastly, they look at JPG's focus on on-chain records can preserve longterm value of NFTs with an eye on how to bridge the various ecosystems in the future and brainstorm around the idea of ZK NFTs.
