Hi @jgx7. Thanks for your question. I think you’re confusing the Zcash Sustainability Fund (ZSF) with the Dev Fund. The ZSF introduces a new approach to issuing block rewards that enables the ability to deposit ZEC from the circulating supply into the ZSF to contribute to future block rewards. Once implemented, unissued ZEC would pay out to block reward recipients directly from the ZSF in a manner consistent with the current process, and with 80% allocated to the block miner and 20% distributed to existing Dev Fund recipients. It’s important to note that we’re not suggesting modifications to how the current disbursements are allocated or changes to existing fee structures. Those matters are for the community to decide. This change provides a mechanism to contribute ZEC to future block rewards through deposits into the ZSF. The deposits can be distributed over time to help sustain and secure the network.
The below thread is an active discussion about the Dev Fund that you might find interesting:
