Zcash marks ten years since its October 2016 launch

What happened

Zcash, the privacy-oriented cryptocurrency frequently likened to Bitcoin, is marking its tenth anniversary this week. The network went live on October 28, 2016, and has continued to develop its technology through extended bear markets and periods when its price lagged behind many other digital assets, according to a recent research note from Grayscale cited by ZyCrypto.

Grayscale attributes that continuity in part to the way Zcash funds its own development. Unlike Bitcoin, where miners collect the entire block reward, Zcash miners receive 80 percent of newly issued ZEC. The remaining 20 percent is directed to a Dev Fund that pays for ongoing protocol work and ecosystem projects. Most blockchains rely on venture capital or other private sources to finance development; Zcash is among the few that write this support into their protocol rules.

The research note points to the network's successive privacy pool upgrades as evidence of the model in practice. Zcash started with the original Sprout pool, moved to Sapling in 2018 and then to Orchard in 2022. In 2026, the Ironwood pool was introduced to address a code vulnerability, and it also brought quantum-recoverable addresses and formal verification of the underlying code. Grayscale said each of these steps was backed by the protocol's own funding mechanism.

Why it matters

The anniversary highlights a rare approach to sustaining open-source protocol work. Because Zcash's funding is embedded in its issuance rules rather than dependent on outside investors, developers have been able to ship privacy upgrades on a fairly regular cadence, according to Grayscale. That structure may matter as the project confronts technical challenges that require long-term research, including scaling transaction throughput and preparing for quantum computing.

Background

Zcash has long been compared with Bitcoin because of its shared origins in the cryptocurrency space, but it differs by offering shielded transactions designed to protect user privacy. Over the decade, its privacy pools have been revised several times, with each iteration intended to improve the underlying cryptography and address weaknesses. Grayscale's note frames this history as a sequence of deliberate, funded engineering efforts rather than one-off changes.

What to watch

Looking ahead, Grayscale expects Zcash developers to keep working on higher transaction capacity, preparation for a post-quantum computing environment and stronger defenses against AI-driven cybersecurity threats. The researchers wrote that sustaining this work will likely require ongoing financial support for developers from a variety of sources and efficient allocation of funding. How the project balances those priorities over the next decade is likely to be a focus for observers.
