Zcash co-founder Sean Bowe has put forward an initiative to revise the current block reward distribution model. According to his proposal, the automatic allocation of 8% of the miner reward to the Zcash Community Grants (ZCG) program should be discontinued, and the freed-up funds should be directed to the Network Sustainability Mechanism reserve.

Bowe's key argument is the sufficient capitalization of the grants program. By his estimate, ZCG already holds assets worth around $125 million, which is enough to continue full-scale operations without additional inflows from the block reward.

How the current model works

The current funding scheme has been in effect since November 2024 and provides for the following block reward distribution:

— 80% goes to miners;
— 8% is directed to Zcash Community Grants for ecosystem development grants;
— 12% goes to a separate fund, the distribution of which depends on decisions by ZEC holders.

Bowe's proposal effectively shifts the emphasis from direct grant support to a long-term network sustainability mechanism. The Network Sustainability Mechanism reserve is intended to provide a financial foundation for the project over a long horizon, while ZCG, according to the initiator's logic, has already accumulated a critical mass of funds for autonomous operation.

The initiative touches on a sensitive balance between incentivizing developers and maintaining mining profitability — redistributing 8% of the reward could affect both the attractiveness of ZEC mining and the pace of ecosystem development if approved by the community.

Cryptalist analysis: The proposal reflects a trend common to mature crypto projects toward transitioning from permanent subsidies to self-sustaining sustainability funds. For Zcash, the key factor will be the reaction of ZEC holders: approval of the initiative would strengthen the network's positioning as financially self-sufficient, while rejection would preserve the current balance of interests between miners and grant recipients.
