Why couldn’t I just do the same without restaking? I can create a rollup with a token, have people stake my token on some L1 contract and then have this kind of round-robin consensus that is being used here. Except that now my rollup has more sovereignty (doesn’t rely in EigenLayer) and more importantly can capture more value (especially MEV). Outsourcing the consensus to EigenLayer isn’t any better than having my own consensus. At least the original based rollup was truly codeless.
Any L2 sequencing that outsources its validator selection to a L1 contract, already inherits the liveness and decentralization of Ethereum. The main differentiators of based rollups still seem to be only two: that it doesn’t require any code and that MEV flows to L1.
MEV flowing to L1 is not desirable for a rollup. If I’m a rollup and I capture more value than my competitors then my token is worth more and I have more resources to hire developers, do marketing, provide ecosystem grants, etc.
It’s also not desirable for Ethereum to capture that much value. If all that value goes to L1, then there won’t be any companies willing to spend billions on rollup projects. Then it would have to be the EF to do all of the work on developing those rollups. An Ethereum where the EF does all the R&D for the ecosystem is not decentralized or neutral.
