Grayscale credits Zcash dev fund as network marks 10 years

What happened

Grayscale has published research arguing that Zcash's decision to set aside one-fifth of block rewards for development has helped the privacy-focused network keep upgrading its protocol as it approaches its tenth anniversary. The asset manager's report, dated Oct. 26 and covered by Crypto.news and Blockonomi, credits the funding model with sustaining research and software work through long bear markets and stretches when ZEC lagged other cryptocurrencies.

Zcash is set to mark ten years since launch on Oct. 28. Under its current design, miners receive 80% of each block reward while development programs receive 20%. That is a different split from Bitcoin, where miners collect the entire block subsidy. Grayscale's head of research, Zach Pandl, said the arrangement has given Zcash a continuing source of support that does not rely entirely on venture capital or private investors.

The report points to the network's sequence of shielded transaction systems as evidence of that investment. Zcash began with Sprout, added Sapling in 2018 and Orchard in 2022, then activated Ironwood in July 2026. Grayscale links each pool to protocol-funded development work. Ironwood followed the discovery of a vulnerability in Orchard's zero-knowledge proof circuit that developers said could have allowed undetectable counterfeit ZEC.

Crypto.news reported that Ironwood went live at block height 3,428,143 on July 28. The upgrade introduced a replacement shielded pool with separate accounting protections, formal verification of supply-integrity properties and quantum-recoverable notes. The recovery feature is meant to support future action if quantum computing threatens existing cryptography, but the reports said it does not make Zcash quantum-resistant on its own.

Why it matters

Grayscale's argument matters because it frames Zcash's funding model as a structural difference from most crypto networks. Blockchains often depend on venture capital or other outside financing for development, while Zcash writes the allocation into the protocol. Pandl said this has provided steady financial support for research, software development and network improvements. The report, titled 'How Zcash Keeps Innovating,' says the model has helped the network continue technical work even when ZEC's market performance was weak. Grayscale also says the funding has supported work without relying entirely on private investment, though the report does not claim the model removes all funding risk. The firm's outlook identifies transaction capacity, quantum computing and AI-powered cybersecurity as areas that will need more research.

What the data shows

In October, Zcash holders approved $8.39 million in grants covering 17 of 37 proposals in the third-quarter retroactive funding round. The approvals included $1.5 million tied to researcher Taylor Hornby's discovery of the Orchard vulnerability, made up of an original bug bounty and a separate community nomination. Other approved amounts included $1.95 million for Zcash Open Development Lab's protocol work, about $1.2 million for ValarGroup's Ironwood contributions, $738,942 for formal verification of Ironwood's cryptographic circuit and $599,000 for external security audits. The figures represent approved funding rather than completed distributions, since some payments still require administrative and compliance review. The next proposal window is scheduled for Oct. 30 to Nov. 13, with voting planned for Dec. 17-29.

Background

Zcash launched on Oct. 28, 2016, as a Bitcoin-like digital currency with added privacy features. Its original Founders Reward supported development for the first four years, according to Grayscale, before governance changes redirected funding to other recipients. The current system divides the 20% development share between Zcash Community Grants, which receives 8% of block rewards, and the Coinholder-Directed Retroactive Grants Program, which receives 12%. The latter lets eligible ZEC holders decide on funding for work already completed, while community grants support eligible development and ecosystem initiatives. The shielded-pool timeline runs from Sprout's zero-knowledge proofs to Sapling's usability improvements, Orchard's newer proving system and Ironwood's security-focused replacement pool.

What to watch

Grayscale expects Zcash to continue work on quantum protections beyond Ironwood's recovery provisions. The reports say developers are already examining changes to transaction signatures and proposals that address privacy risks from future cryptographic attacks. Pandl also flagged transaction capacity and AI-powered cybersecurity threats as areas requiring further research. He said future progress would likely depend on financial support from several sources and careful allocation of development resources. The next grant cycle, and the network's ability to fund work through it, will be a practical test of the model Grayscale describes.
