S9 E4 | What is Data Availability? w/Rene Lubov (Celestia)

Rehash: A Web3 Podcast

In this episode, we’re speaking with Rene Lubov, software engineer at Celestia, about data availability (DA), or what Rene prefers to call data publishing.

Rene is one of the founding engineers at Celestia and breaks down for us everything we need to know about DA and how it’s implemented at Celestia. We also talk about modularity in blockchains, light nodes, and other technical concepts that you may have heard of before but maybe don’t have a clear understanding of just yet. She does a great job of explaining all of these concepts clearly.

On a more personal level, Rene also shares about her background, how she taught herself to code, what protocol engineering is (hint: it’s very different from app development or smart contract coding), what it was like being a founding engineer at Celestia, and her experience as a woman in crypto having joined way back in the early days.

Rene was nominated for Rehash by Tina and voted onto the podcast by Tina, Jimmy Chang, Hudson Jameson, Queen Wartooth, and David Phelps.
