ZK fraud proofs: RISC Zero and Layer N merge optimistic and zk rollups
Quote88 words
Commentary on RISC Zero and Layer N's ZK fraud proof system: optimistic rollups struggle to keep fraud proofs small, zk rollups face expensive proving, and proving fraud in zk keeps proofs succinct while saving cost versus full zk rollups.
Key claims
zk proving fraud is cheaper than a full zk rollup
Succinct proofs keep fraud proofs small and easy to verify
this is sick! 🤯
allows to combine benefits of both optimistic & zk rollups into one system! 🚀
truly the next generation of ORs 👀✨
1/4
a core issue optimistic rollups are facing is to keep fraud proofs small & simple to verify
2/4
zk rollups face the problem that proof are slow & expensive to generate (at least for now)
3/4
zk proving fraud saves cost compared to zk rollups, while the succinctness property of #zk proofs ensures small fraud proofs that can easily be verified
4/4
