Shielded Assets (ZSA/UDA) for DeFi on Zcash

The four committee members present formally voted to approve the QEDIT grant. Hudson had already expressed his full support, making it a unanimous decision.

(QEDIT) Forum discussion ; $1,187,615 Brian began by saying that overall the community is very excited; the grant is well put together and thought out; he had questions of the security aspect and changes to core protocol; they will require auditing; how do we audit what previous auditors are adding into the code?; there are multiple eyes from ECC and everyone else involved; he is an enthusiastic yes! Aditya seconded Brian’s comment that he is pleased that ECC is going to work with them on a complex protocol level integration; he is a thumbs up with the requirement that they give a monthly update on the status. Michael stated he is super enthusiastic and wants them to get working ASAP; hell yes! Jason agreed with the other members; he very much supports and approves the proposal; ZSAs are an important use case for Zcash, particularly private BTC and stablecoins, which will lead to a number of other applications; QEDIT are well-respected and have strong ties with ZF and ECC and this project is in line with the ZCAP poll (UDAs were voted to be the highest priority); it is very technical so he can’t comment on all the technical specifications or timeline but it’s evident there is close contact with ECC and ZF so it will be properly evaluated; he agreed that they should have monthly updates to see how the project is evolving. Brian commented that this discussion aligns with the desire to bring teams into the ecosystem that have the desire to contribute meaningfully over the longer term; this team brings value to the ecosystem; maybe ZOMG hasn’t seen these type of requests before because the ecosystem might not know what ZOMG is looking for i.e. reporting, roadmaps, plans; they might need to have a separate discussion for requirements and what they are looking for; if QEDIT wants support long-term, they can put a proposal together instead of relying on several short-term grants. Aditya agreed that that is an important point; as MGRC is being developed they should have a chat as a team but focus on attracting teams for now; Funding Zecwallet is something they should look for. Jack informed ZOMG that Zecwallet will be updating at its current state but won’t be adding additional features. Aditya suggested they put out of RFP for that and asked since Zecwallet full node is under zcashd and funded by grants from ZF, is it still under ZF control? Jack clarified that Zecwallet was never under ZF control; ZF worked with the developer and the developer subsequently received grants from ZOMG for work that has now been completed. The four committee members present formally voted to approve the QEDIT grant. Hudson had already expressed his full support, making it a unanimous decision. The committee agreed to have Dan draft a response that includes the requirement to provide monthly updates and run it by the committee before he posts. Resources for ZOMG: Jason asked that, although it’s not an issue for this proposal, what resources does ZOMG have to evaluate technical aspects or proposals?; Do we have an open line of communication with ECC/ZF? Alex replied that Dan can reach out to the relevant people at ZF and ECC; he is conscious of the time involved in these asks and wants to make sure he reaches out to the best person; the point of RFIs is to have experts we can reach out to and pay- this is the ultimate goal; in the bridge time, we can reach out on behalf of ZOMG; ZF has reached out to ECC/ZF twice for the past committee; ZF is happy to facilitate if ZOMG has specific questions they want answered and, in the long-term, would like to see an expert list that can be supplemented by ECC and ZF. Inherent Risks: Jack brought up that there is always a risk that a project might not deliver or might not be on time; there is an inherent risk in grants of this nature for a cutting edge sector of cryptocurrency; some will not deliver so he accepts that as an outcome and the community should also; as long as ZOMG and ZF do our due diligence, if anyone complains, Jack will stand up for ZOMG; experiments and failure are a part of this world; he encouraged the committee to embrace a little bit of risk taking, and Jack and ZF will stand alongside ZOMG if there is criticism. Aditya agreed; there might be a delay or they might need to request further funding to continue; as we go into POS, it might require more work as well.
