[SOLUTION] Please describe your proposed solution

Having built a multi-sig DAO previously on Plutus, we have first hand experience of the limitation of the computation resources (memory/cpu) and tx size while trying to make the DAO scalable.

While it is possible to use simple multi-sig transaction that can scale relative better than the plutus based multi-sig, the flexibility to add or remove participants on the multisig/DAO is limited or requires ugly workarounds.

Our proposal is to leverage Schnorr signatures to build a multi sig DAO that can scale well among the hundreds of participants with the following features:

• Add/remove participants on the DAO
• Support for proposals and voting actions
• On-chain and off-chain signing support

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

Multi-sig/DAO has their own uses on Cardano and beyond. This project besides the original purpose of having an scalable DAO that benefits the cardano community, it also showcases what can be done Cardano using the cryptographic primitives that are available now and on Plutus v3.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

The proposing team is KuberIDE team, who has a track record of development of projects like KuberIDE, mempool explorer, Plutus contracts and NFT marketplaces, many of which are open source.

For this project specifically, we have first hand experience on the limitations and how we can resolve those limitation. We have internally done a proof of concept to understand the feasibility of the solution. Now, we would like to build a proper reference implementation to open-source so that broader developer community can benefit.
