I try to put the best pieces of various proposals together. A 20% of the block reward for a 4-year development fund that disburses to a trust controlled by both the Electric Coin Company (ECC) and Zcash Foundation (ZF), but with stringent controls on how funds may be allocated. It sidesteps code complexity in implementation by off-loading disbursements to a legal trust; funds the ECC/ZF; ECC stays a for-profit with restrictions; funds external parties through ZF Grants; all while carving out a limited-scoped opportunity for extending governance to more groups than the ECC/ZF.
Zcash won't thrive without a dev fund. I wish this wasn't true (I really do), and for the longest time I was against the idea. But I've come to fear the alternative without one; I fear the privacy technology pioneered by Zcash may never reach its true potential — not just for our community, but for others interested in novel approaches to private money.
The Foundation, ECC, and broader community has offered many suggestions and guidelines for a potential dev fund, below is my attempt at synthesizing them into a compromise that's greater than the sum of its parts:
for security reasons, it may be useful to refine the "single address" to a list of rolling addresses as described in section 7.8 of the current protocol specification. Other references to a "single address" in this document have not been changed.
Please note: a previous version of this proposal included a portion of the funds being tied to shielded adoption, based on ideas brought forward by Eran Tromer in 4. After many discussions I came to worry about the gameability of the metric and decided to drop it entirely.
Upon the NU4 network activation, 20% of the mining reward (post-Blossom / post-halvening = 0.625 ZEC per block) MUST go to a single shielded address with a viewing key widely distributed and known to the community and controlled by a trust established by the ECC and Zcash Foundation. If the trust and associated address aren't established by the NU4 activation deadline, then there MUST NOT be any change to the mining reward. Every quarter-year (105,000 blocks at the post-Blossom rate), until 4 years after NU4 activation (1,680,000 blocks at the post-Blossom rate), the trust SHOULD disburse funds the following way, requiring a public report with every disbursement:
When this proposal was written it was expected that NU4 activation would correspond exactly to the first (October 2020) halvening. Since that may not be the case, I have resolved a potential ambiguity in the original wording by specifying that the trust disburses funds for 4 years, rather than that it disburses funds until the second (October 2024) halvening.
0.625 ZEC * 105000 = 65625 ZEC accrued in the trust every quarter. If both the ECC and Zcash Foundation met the accountability requirements set by the trust, then disbursements would look like this:
This example assumes no change to target block spacing.
Here I'm borrowing from the Foundation's guidance 3 but adding some stipulations to cement the Foundation's independence, prevent the Foundation from hoarding its endowment, and handle the ECC as a for-profit. Before disbursing funds each quarter, the trust MUST validate that both the ECC and Zcash Foundation:
For the Zcash Foundation, the trust MUST further require:
Additionally, for the ECC, the trust MUST validate the following before each disbursement:
The ECC MUST share necessary information with the trust to ascertain no violations of the above, but the information itself (i.e. cap table and detailed financials) SHOULD remain private between the ECC and the trustees unless there is a violation that is not cured.
The violating party has 30 days to attempt to cure the violation (if it's possible). If they cannot, future funds MUST be redirected to ZF Grants via a restricted donation to the Zcash Foundation. (That is, not usable by either the Zcash Foundation or ECC, more on that below.)
A portion of the dev fund goes to the Foundation but with the express (and restricted) purpose of being distributed via ZF Grants (a restriction that MUST be legally enforced by the trust). The Foundation would continue to administer ZF Grants and distribute funds, but it SHOULD NOT decide where those funds go and would not allowed to be recipients of these funds; instead, the trust MUST demand that the ZF Grants process include broader input in the manner described below. In the discussions around the various "third party" proposals, some have suggested a 3-of-5 approach where the ECC and Zcash Foundation are in the minority; I think that structure would work well for these funds. It's not the full dev fund so we are limiting the downside risk of selecting the "wrong" third parties, which also means we can give those third parties more voice (by making them outnumber the ECC/Zcash Foundation). The Foundation MAY also chose to fund ZF Grants beyond the restricted donations from the trust, but doing so would be at their discretion.
Thanks to the discussion on Matt Luongo's proposal there's a good blueprint for how this group would work. I'm borrowing some comments I made on Matt's proposal thread 8 and modifying them to apply to a ZF Grants-specific Grant Review Committee, rather than the Foundation's board.
The ZF Grant Review Committee would be compromised of five members, voted on in the following manner:
The group would meet biweekly to make funding decisions, the results of which will be made public on ZF Grants. Taking a note from Eran Tromer's recent proposal, the group would have a goal of making at least two "Large Grants" every year. A "Large Grant" would have an expected scope of six months and 1/4th to 1/3rd of the total ZF Grants yearly budget, with the goal of getting more dedicated external teams involved.
There are scores of great ideas on the forums, and I took the (subjective, mind you) best parts of each into a proposal that hopefully meets the standards of the ECC, the Zcash Foundation, and the broader community.
With all due respect to the proposers behind some variant of a "2-of-3 multisig" decision-making process for all disbursement decisions: I think this is a bad idea. To quote a previous forum post of mine:
...2-of-3 multisig [is] better if we find the right third party. That in and of itself requires an additional process/mutual agreement between the three parties (which is much more difficult than a bilateral agreement), and as I’ve mentioned before in presentations in the past, 2-of-2 with known entities dedicated to Zcash is better than jumping straight to 2-of-3 with a third party hastily decided or staying with 1-of-1 entity trademarks and software development processes.
As for why 2-of-2 is still strictly better than 1-of-1: in the case of cryptocurrency governance, I believe that inaction in the case of disagreement is a better outcome than one party unilaterally exercising power.
More to the point, I worry that the "third party" in question is being idolized into some Platonic ideal, and in reality either the ECC or the Zcash Foundation would spend a great deal of their time currying favor in either the process or selection of the party in question in the limited time between now and that party's selection. Given that the Zcash Foundation is charged with representing community interests, I'm not sure why another community-focused representative would really make sense from the ECC's perspective — they'd be constantly outvoted if interests clashed, so from a balance of power perspective I'm not sure why the ECC would find that tenable. And I'm not sure the community would want the "third party" to be another profit-generating enterprise, like a VC or another startup, which would tip power another way.
The crux of this proposal still centers around the idea that the Zcash Foundation and ECC share responsibility for protocol development, which is now bolstered by the 2-of-2 agreement on the trademark. It assumes and expects that both continue developing consensus-compatible node software that interacts with the Zcash network. But it mandates accountability for disbursement of funds to the ECC/Zcash Foundation, and expands outside stakeholder input on funds that wouldn't be earmarked for the ECC/Zcash Foundation (similar to Placeholder's earlier version of their proposal and Matt Luongo's current proposal), while it doesn’t preclude the possibility of migrating to broader "2-of-3" later on future governance decisions.
The main reason: reducing complexity creep in consensus code. Rather than try to incorporate some complex mechanism for dev fund disbursements on-chain, we can meet the NU4 with the simplest possible code-change and spend more time ironing out the details of the trust "off-chain." Since both the ECC and the Zcash Foundation are based in the US, using a trust with well-specified criteria for disbursements is a reasonable path. This also fits in nicely with lex-node's proposal 9 for legal covenants on funding.
The biggest issue is custody of the funds under the trust's control, but I suspect this can be managed with a partnership with a custody partner. There's also the issue that non-public information would need to be verified and validated by the trust, but I view this as a net positive for the community ("transparency for organizations, privacy for individuals").
TBD, but it should be relatively simple to code in both zebra and zcashd.
