Developer funding on Zcash has become a central talking point as the privacy-focused network approaches its 10th anniversary on October 28. Grayscale, a digital asset manager, credits the protocol's decision to route 20% of block rewards to a development fund for sustaining a decade of continuous research and development.

Zach Pandl, Grayscale's Head of Research, laid out the argument in a research note titled How Zcash Keeps Innovating, published this week. According to the note, Zcash kept evolving through prolonged bear markets and stretches in which ZEC lagged other cryptocurrencies. For readers tracking protocol sustainability, the note doubles as a case study in how a network can keep shipping through market cycles when development budgets are tied to block rewards rather than to fundraising rounds.

How the Dev Fund Works

The funding model sets Zcash apart from Bitcoin. On the Bitcoin blockchain, miners receive 100% of the rewards attached to each block. Zcash miners, by contrast, earn 80% of ZEC block rewards, while the remaining 20% flows to the Dev Fund, a pool of capital that supports Z development and related ecosystem initiatives. As a result, miners on Zcash receive a smaller share of each block reward than their Bitcoin counterparts. Because the split is written directly into the protocol, the Dev Fund operates as a recurring funding stream tied to network issuance rather than a budget that must be re-raised from investors.

Pandl noted that most blockchains depend on venture capital or other forms of private funding. In contrast, he described Zcash as "one of the few networks to build ecosystem funding directly into the protocol," and credited that structure for the network's progress.

"One important reason behind this continuous innovation has been the protocol's consistent financial support for R&D," Pandl wrote.

Grayscale describes Zcash as a Bitcoin-like digital currency with additional privacy features. The network turns 10 years old this week, on October 28, and developer funding remains embedded in the protocol design. The pools that deliver those privacy features have changed repeatedly over time, even as the funding mechanism has stayed in place.

Privacy Pools and Network Upgrades

The introduction of new privacy pools stands out as a clear example of that innovation. These pools form the underlying structure that gives Zcash its privacy characteristics. The network launched with the Sprout pool, a timeline Pandl presented in Exhibit 1 of the note. Sapling followed in 2018 and Orchard arrived in 2022. Ironwood, the newest pool in the sequence, launched in 2026 to address a code vulnerability, with Grayscale linking the upgrade directly to that security issue. In all, the network now runs four privacy pools, and Pandl stated that protocol-based funding supported each of them.

Ironwood introduced quantum-recoverable addresses along with formal verification, a technique that uses mathematical proofs to establish specific properties of code. The post-quantum angle reflects a broader preoccupation across the cryptography field, where researchers are weighing how today's public-key systems would hold up against future quantum computers, a question the note places among Zcash's forward priorities.

Looking Ahead

Grayscale expects this record of innovation to continue. "We hope and expect that Zcash will continue to innovate," Pandl wrote. The firm points to three priorities: scaling transaction capacity, preparing for a post-quantum future, and protecting against AI-powered cybersecurity risks.

Meeting those goals will likely require "ongoing financial support for developers from a variety of sources," Pandl added. The note also stresses the efficient allocation of Zcash developer funding, and its key takeaway states that a "culture of innovation may help Zcash stay prepared for a post-quantum future." How that support takes shape in the network's second decade, and whether protocol-embedded funding remains the backbone, figures to be one of the storylines to watch as Zcash crosses the 10-year mark.
