Other sidechains on the Stellar network besides ZkVM?

Question

Premise: I'm still in the learning process of anything that is blockchain and Stellar

I've recently discovered ZkVM (here a nice article: https://medium.com/stellar-developers-blog/zkvm-a-new-design-for-fast-confidential-smart-contracts-d1122890d9ae) and I'm understanding that this is a protocol that can be used to become a sidechain of any blockchain. Quote from the technical white paper:

A ZkVM blockchain can work with any consensus protocol, from proof-of-work to Federated Byzantine Consensus.

source: https://github.com/stellar/slingshot/blob/main/zkvm/docs/zkvm-design.md

The team behind ZkVM worked for or in collaboration with Interstellar, so it is heavily promoted for (and I guess built for) Stellar. And I'm understanding that the specific implementation for Stellar of ZkVM is Slingshot, again a project by Interstellar.

Since I've discovered ZkVM, I've been wondering whether there are other Stellar sidechain projects. Anyone knows?

Responded on Reddit but will respond here as well.

OrbitLens is also working on a sidechain called Project Centaurus.

Project Centaurus is the second layer payment network, exchange, and scaling solution for Stellar. It's a platform with very high throughput that allows a few independent organizations to create a protected decentralized segment on Stellar Network with a multisig vault account. Users can instantly transfer/trade tokens inside the cluster with zero fees.
