Podcasts: S15 E36: Eli Ben-Sasson on STARKs, Rollups & Privacy 🔗 15 weeks ago

Back in 2014, Eli Ben-Sasson co-authored the Zerocash paper, which proposed a ZK SNARK system that creates anonymous Bitcoin payments. Around the same time, he also spoke about the compression benefits of zero-knowledge proofs – a full Bitcoin node can be synced within seconds just by verifying against a valid proof.

More recently, he became interested in STARKs and built a company around this cryptographic breakthrough. If SNARKs require a trusted setup, then STARKs are a major leap towards trust minimization.

If Bitcoin activates the OP_CAT soft fork, then this ZK rollup scheme also becomes possible to enable great privacy and low-sized transactions.
