This post is actually better than the whitepaper
But in general the project seems to be very similar to most of those I analyzed in the Sidechain observer (which are those on
https://l2.watch which already have mainnets). I disagree with the author a bit in that for me the biggest downside is the centralized bridge, not the absence of smart contracts with a turing-complete language. Because wBTC-style bridges with trusted custodians already exist on several chains where you can use them for EVM-compatible (or not) contracts.
Interesting in further comments the label "parasite chain". But I glazed over when I saw the term "fractinals".
I sort of agree with the definition of a "parasite chain" being a chain without a trustless bridge. It seems to have more "parasite characteristics":
- premined, i.e. with big benefits for the founders
- introduces more load to the Bitcoin L1, due to the posted merkle roots.
I stumbled upon the assumption "MPC-based bridging" being the same than "multisig". It seems the big question is though who is part of the federation. In most MPC designs I have seen it seems to be rather similar to the Liquid federation, essentially a static number of custodians who can in some cases vote to introduce a new member. But I'd not rule out a design like Nomic (with a more descentralized approach) could also be done with MPC.
P.S. Guy with name "altcoinsignal" makes sole post about some vaguely Bitcoin-inspired alt and says it's not promotional.
Quite obvious of course
However, I'm personally strongly in support of discussing L2 projects, even if they are very poorly programmed, in the Bitcoin sections, as long as they at least promote to enhance Bitcoin's functionality - if they're a scam, we can lead newbies to the arguments collected in these threads then.
