Speaking for ZF, we would solicit donations from the Zcash community, and likely explore other sources of donations and grant funding, although that would likely have implications for our ability to focus our efforts primarily on Zcash.
I posted a summary of the economic state of the Zcash ecosystem a few weeks ago. With the current market price of ZEC, our current burn rate is approximately 2.2x the value of the ZEC we receive from the Dev Fund, and we have a little over two years of runway.
I think it’s safe to say that there’s going to be significant change at ZF, no matter what happens with the Dev Fund.
