Bitcoin and Beyond EP1: Citrea's ZK Technical Design Explained

The Rollup - A podcast by The Rollup

Categories:

Welcome to the first episode of our Bitcoin and Beyond presentation series. We aim to provide you with technical knowledge about the state of different Bitcoin scaling solutions. Are they sidechains? L2s? True rollups? For the first episode, we're diving into Citrea, a project focused on bringing ZK to Bitcoin with a true rollup design (using Bitcoin for data availability). We sat down with Orkun Kilic, to discuss Bitcoinโ€™s security and ZK. Citrea is designed to use state differences and ZK proofs, making data usage more efficient and scalable from the jump. This approach overcomes the traditional limitations of Bitcoin, allowing for sophisticated onchain operations beyond simple transactions. But, is using Bitcoin for data availability really a feasible path? We asked Orkun about this and more. Citrea also introduced, Clementine, a peg mechanism which minimizes trust and ensures that BTC can be used seamlessly across different layers. By (soon) utilizing BitVM for optimistic verification of ZK proofs, Clementine provides an innovative way to maintain Bitcoinโ€™s robust security while facilitating efficient data and state transitions. Again, we asked Orkun just about all that we could to really understand why they've chosen to design Citrea in the way they have and he answered thoroughly. Welcome to Bitcoin & Beyond. Lets have some fun.
