Zcash Shielded Pool Holds Nearly 29% of Mined ZEC

Nearly 4.9 million ZEC, close to 29% of all coins ever mined, now sit in Zcash’s shielded pool. Shielded transactions let the network verify payments without publicly revealing the sender, recipient or amount, while users can share viewing keys to disclose selected details. Grayscale Research’s Michael Zhao argues that AI is making financial privacy more urgent by lowering the cost of linking wallet addresses to real people.

Why it matters

Public blockchains preserve transaction histories indefinitely. As AI improves at matching wallet activity with exchange accounts, leaked data, social media and timing patterns, transactions once difficult to attribute may become easier to connect to individuals. That reach can extend backward, exposing older activity as new analysis tools emerge.

The concern extends beyond personal transfers. As businesses move stablecoins, payments and trading activity onto public networks, visible payrolls or supplier relationships could reveal commercially sensitive information. Zcash’s approach is to make disclosure a choice: a user can share a viewing key with a regulator or business partner without giving up control of funds. Whether that selective disclosure satisfies regulators accustomed to broader reporting remains an open question as AML rules and the EU’s MiCA framework shape the market.

Market impact

Shielded transactions have grown sharply over the past two years, while transparent Zcash transactions stayed flat. The share of mined ZEC held in the shielded pool offers a measure of adoption beyond simply holding the coin, and a larger shared pool can strengthen privacy by making individual activity harder to isolate.

ZEC rose roughly 2,300% between September 2025 and September 2026. Grayscale launched a spot Zcash investment product on the NYSE in August 2026, attracting nearly $1 billion in assets in just over a month. The figures point to investor interest alongside increased shielded use, but regulation remains a key test for Zcash’s effort to bring privacy features into mainstream finance. An upgrade called Ironwood, released in July 2026, replaced part of the system’s cryptographic engine and fixed a known security issue.
