Crypto’s Anti-Surveillance Boom: Zcash, Monero and the Return of Anonymity

Why It Matters

The surge signals a market re‑orientation toward anonymity as investors seek protection from surveillance and regulatory risk, potentially reshaping crypto adoption and prompting tighter compliance frameworks. It also underscores the growing relevance of zero‑knowledge technology in mainstream financial products.

Summary

Privacy-focused cryptocurrencies have surged in the second half of 2025, with Zcash rallying over 700% since late September to overtake Monero as the largest privacy coin by market cap. About 25% of ZEC’s circulating supply now resides in shielded addresses and roughly a third of its transactions use the encrypted pool, driven by default‑privacy wallets like Zashi. The rally extends to other early privacy projects—Monero, Decred and DASH—while Bitcoin and Ether slump, highlighting a shift from institutional ETF‑driven flows to individual demand for untraceable digital cash amid heightened regulatory scrutiny. Analysts link the boom to broader concerns over AI‑enhanced surveillance and recent legal actions against privacy tools such as Tornado Cash.
