Congratulations on the recent development by Arbitrum’s team on tackling the Delay Attack on Rollups.
Cartesi is another Optimistic Rollups solution that has also been researching this same problem. And given the broader interest on the issue, we’ve decided to published a preliminary version of our permissionless validator solution on arXiv. We hope it can add to Arbitrum’s work on the issue.
We at Cartesi are excited to connect with anyone who’s interested in discussing this topic.
