This is not accurate. Optimism *will* still have on-chain fraud proofs as part of the 2.0 system. I think you are misunderstanding the blog post.

> Even worse is the fact that we are delegating all the trust to the Optimism team.

Again, not true. Anyone will be able to run a validating node, and anyone will be able to execute the fraud proofs.

I apologize for this, I may have misunderstood this part then. I'll be more than happy to fix these statements. Can you share some docs or a brief description of how fraud detection for rollups work? Thanks!
