I wanted to share some insights on your query, from my perspective as someone who is actively immersed in developing offchain voting solutions for the Ethereum ecosystem.
To start with, zk-POPVOTE, as I see it, is a ground-breaking voting solution with the potential to introduce onchain, token-based anonymous voting to DAOs. The emphasis here is on “token-based”, which is a capability that neither OVOTE nor any other current solutions can provide.
In scenarios where DAOs prefer to structure their governance based on ERC20 or NFTs (as opposed to a list of signers like a Multisig or OVOTE), while also having gasless and/or privacy capacities, a system such as zk-POPVOTE becomes indispensable. While minor tweaks could bring up potential alternatives, the core concept is the same. For more details, you might find my recent article useful: Road to Anonymous Binding Voting for Ethereum
The PoC research being conducted by AZKR and Aztec could potentially revolutionize DAO governance. However, I’d be remiss not to mention that this is not a short-term achievement due to the heavy computation required on the browser scope (proving several Ethereum storage-proofs within a zkSNARK is quite resource-intensive). But the encouraging news is that what seemed impossible a few months back is slowly becoming a reality.
Regarding Tally CLI, it indeed doesn’t directly benefit Aragon OsX. But, it serves as a crucial tool for testing and evaluating the proof-of-concept, an essential phase in the development of such systems.
In my view, AZKR should continue to push the envelope in this direction, without the pressure of delivering a finished product in the near to medium term. The complex nature of this endeavor calls for patience, research, and time.
Lastly, I’d like to comment on TLCS, which is crucial for enabling “shielded” or “secret until the end” voting, a very important feature for any kind of democratic governance. At Vocdoni, our goal is to integrate this service in the future, as it enhances our current solution.
Do bear in mind that this response is strictly my personal viewpoint, not endorsed or reviewed by any member of AZKR. I genuinely hope this provides some clarity and a better understanding of the objectives at hand.
