Wu Blockchain reports that digital asset management company 21Shares has published a research article stating that the market cap of the privacy coin sector has grown nearly fivefold over the past year, from $6.2 billion to approximately $30 billion. Among them, Zcash's market cap is around $20 billion, marking a roughly 400% increase from its 2021 peak. 21Shares highlighted that privacy coins are the only crypto sector in its analysis to surpass the October 2025 high, up 216% from that peak. The firm believes that transaction and holding information on public chains could expose institutional strategies, making transaction confidentiality a key condition for institutional blockchain adoption. Ethereum and Solana are advancing privacy features, while networks like Canton are offering controlled information disclosure mechanisms tailored for institutions. https://www.(wublock123.com)/news/21shares-privacy-coins-market-cap-up-5x-to-30b-68800
