Privacy Tokens Zano and Firo See Renewed Interest as Demand for Untraceable Transactions Grows
Zano (ZANO) and Firo (FIRO) appeared simultaneously on the CoinGecko trending list on May 14, drawing attention to a privacy token sector that has remained largely dormant since a brief resurgence in late 2024. Zano trades near $11.30 with a market cap of $172 million at rank 208.
Firo sits lower at rank 873, trading near $1.19 with a $22 million market cap. Both tokens fell in the same 24-hour window, with FIRO down 14.2% and ZANO down 2.9%, suggesting the trending placement reflects search and social interest rather than price-led momentum.
What Separates Zano and Firo Technically
Both tokens are purpose-built for untraceable transactions, but they take different technical approaches to achieve that goal.
Zano, launched in 2019, uses ring signatures and stealth addresses to obscure the sender, receiver, and transaction amount on its blockchain. Ring signatures bundle a real transaction with decoys drawn from the existing transaction history, making it statistically difficult to identify which participant initiated the transfer.
Firo, formerly known as Zcoin, uses a different approach called the Lelantus protocol.
Lelantus allows users to burn coins and redeem freshly minted coins with no transaction history attached, effectively breaking the on-chain link between a user’s prior activity and their current holdings. The Lelantus design eliminates the decoy-set limitations that affect ring-signature-based systems, though it introduces different trust assumptions around the cryptographic parameters of the burning mechanism.
The distinction matters for users evaluating privacy guarantees.
Ring-signature systems like Zano’s provide probabilistic privacy, where the transaction is hidden among a set of decoys. Lelantus-style systems like Firo’s provide categorical privacy, where redeemed coins carry no provable history.
Neither approach is universally superior; each involves trade-offs between computational cost, user experience, and the strength of the privacy guarantee.

Background
Privacy tokens as a category experienced significant regulatory pressure between 2021 and 2023. Several major centralized exchanges delisted Monero, Zcash, and Dash in response to guidance from financial regulators in the European Union, Japan, and South Korea.
That wave of delistings removed a large share of the liquidity available to retail traders seeking privacy coin exposure through centralized venues.
The sector’s trading activity migrated partly to decentralized exchanges and peer-to-peer platforms during that period. Zano and Firo both retained listings on a smaller set of exchanges and continued development through the delisting cycle.
Firo’s team published research on an upgraded protocol called Lelantus Spark in early 2024, which the project said offered stronger privacy guarantees and better scalability than the original Lelantus design.
Zano and Firo both appeared in a prior Nonce trending scan roughly four hours before this report, suggesting the dual trending placement has persisted across multiple CoinGecko ranking cycles in the May 14 window. That persistence across consecutive scans is unusual and may indicate a coordinated social media campaign, organic search interest driven by a specific event not yet captured in primary sources, or renewed discussion of privacy technology in legislative and regulatory forums.
Colorado and Illinois both introduced AI data privacy bills in their May 2026 legislative sessions, according to reporting by Colorado Politics and the Chicago Tribune.
While those bills target AI data collection rather than cryptocurrency privacy, the broader public conversation about data privacy and surveillance may be lifting interest in privacy-preserving technologies across both AI and cryptocurrency sectors.

What to Watch
For both ZANO and FIRO, the 48-hour test is whether the trending placement translates into sustained volume growth. Zano’s $1.29 million in 24-hour volume is thin relative to its $172 million market cap.
FIRO’s $617,000 in volume against a $22 million market cap represents a slightly healthier ratio but remains well below the thresholds that typically precede lasting price recoveries.
The sector as a whole will benefit from any primary-source development: a new exchange listing, a protocol upgrade announcement, or a clear regulatory statement that either restricts or accommodates privacy coins in major markets. The two-year regulatory uncertainty that followed the 2021-2023 delistings created a suppressed baseline for valuations.
A resolution in either direction would give investors a clearer framework for sizing positions in ZANO and FIRO at their current prices.
