Privacy used to mean disappearing entirely from view. Now it means being seen on your terms.
As surveillance continues to sharpen and institutions arrive on-chain, the sector has split into generations, with one side receiving a heavy bid while the other is left for dead.
But before we go over which projects lived, died, and are on the rise, let’s take a look at how the terminology and utility of on-chain privacy platforms are evolving.
<h2 id="the-changing-face-of-privacy">The Changing Face of Privacy</h2>
For most of crypto's history, "privacy" was essentially synonymous with “anonymity”—break the link between you and your <a href="https://coinmarketcap.com/academy/glossary/money" rel="noopener noreferrer nofollow">money</a> and call it a day.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/747a9c5b4fd94f8e8154dfaf6310db1d.png">
That worked when crypto was mostly about moving value around. It works less well now that AI can de-anonymize transparent chains by reading transaction patterns, and now that those who want privacy aren’t just cypherpunks but also pension funds.
The definition has shifted from invisibility to selective disclosure.
As Aleo founder Howard Wu put it, the aim is "proving what regulators need to see without exposing everything to everyone."<img src="https://academy-public.coinmarketcap.com/optimized-uploads/ff353961201b466eb91c63d9ce9106aa.png">
A bank can't run payroll if every salary is public, and a trading desk can't reveal every position without wrecking its own price discovery. Regulated institutions need privacy that is compliance-ready, while individuals typically just want freedom from surveillance.

<h2 id="privacy-goes-institutional">Privacy Goes Institutional</h2>
Aleo's own work is a clean example of the changing trends.
Its zero-knowledge layer-1 (L1) hosts USAD, a private stablecoin issued via Paxos and backed by regulated reserves.
The L1 also powers a private payroll product (with Toku) with several integrations that enable salaries to be settled on-chain. This is confidential by default but still auditable to regulators.
Zama is chasing the same goal with <a href="https://coinmarketcap.com/academy/glossary/fully-homomorphic-encryption" rel="noopener noreferrer nofollow">fully homomorphic encryption</a> for regulated asset tokenization, while Aztec's ZK layer-2 (L2) lets developers write "programmable selective disclosure" that allows users to prove transactions are compliant without revealing all the details.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/e358d99eb4a24bb18825ba51474ad546.png">
The institutional heavyweight is the <a href="https://coinmarketcap.com/currencies/canton-network/" rel="noopener noreferrer nofollow">Canton Network</a>, a privacy-enabled "network of networks" with sub-transaction privacy. This means each party to a deal sees only the slice that concerns them. For example, in a delivery-versus-payment trade, the cash bank sees the payment while the securities registrar sees only the asset leg.
Its roster reads like a Wall Street guest list: 600-plus institutions, Visa as a Super Validator, and the DTCC joining to tokenize US Treasuries on Canton rails.
Institutions "can transact together while only seeing what they need to see," as one analyst put it.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/f992e3b56dc349569967d3f159f3ed49.png">
But before we crown the institutions, the old guard deserves its due, because it's having a very good year.
<h2 id="the-old-guard">The Old Guard</h2>
If you'd written off Monero and Zcash, the 2026 tape would like a word.
<a href="https://coinmarketcap.com/currencies/monero/" rel="noopener noreferrer nofollow">Monero (XMR)</a> remains the undisputed king of pure transaction privacy, fusing ring signatures, stealth addresses, and RingCT to hide the sender, receiver, and amount by default. Despite years of exchange delistings (over a dozen in 2025 alone), it has refused to die.
It currently trades at around $400 with a $7.3 billion market cap, ranking No. 16. Not bad for a community-funded project with a regulatory target on its back.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/c46428bd8e3647d28224cd0debbd45f1.png">
But in terms of pure momentum, <a href="https://coinmarketcap.com/currencies/zcash/" rel="noopener noreferrer nofollow">Zcash (ZEC)</a> is this year’s real standout.
The zk-SNARK pioneer has gone parabolic: ZEC was up more than 1,400% on the year at one point, and now sits near $570 with a market cap just shy of $10 billion.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/73d24993c6e9486ea989820d1c0e4806.png">

What's driving it? A genuine catalyst stack: heavyweight backing from Multicoin Capital and a cleared SEC case after the agency closed its probe into the Zcash Foundation in January 2026. Add a Robinhood listing for retail access and Grayscale's filing for the first-ever US spot privacy-coin ETF, and the institutional door is suddenly wide open.
Turns out being early (and surviving) is a hell of a strategy.
<h2 id="the-old-new-guard">The Old New Guard</h2>
Then there's the cohort that was supposed to be the future but largely failed to live up to the hype.
The 2021–2024 wave of zero-knowledge L2s arrived with stratospheric valuations and almost no float. StarkWare raised $100 million for Starknet at an $8 billion valuation in 2022, and zkSync carried similar hype.
But the growth in each token supply vastly outstripped the actual usage-based demand. Most L2 tokens dropped below their issuance price within 12-18 months (e.g., ZKsync down 75%, Starknet down 90%). They’ve been practically down-only since launch.
The on-chain story isn’t quite so harsh.
Starknet's total value locked (TVL) plummeted from a peak of ~$1.68 billion secured to ~$624 million as of writing.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/de83befaa9994ccc8ec5d42955e0a5c6.png">

Daily active addresses dropped to as low as ~3,800 but have been picking up throughout 2026, thanks to the success of the perp <a href="https://coinmarketcap.com/academy/glossary/decentralized-exchange-dex" rel="noopener noreferrer nofollow">decentralized exchange</a> known as Extended.
Early repeated outages didn't help matters, including a four-hour mainnet halt in January 2026, the second major failure in under four months.
As DeFi researcher @SeniorDeFi flagged during an earlier outage, "uptime is not optional."<img src="https://academy-public.coinmarketcap.com/optimized-uploads/e7070758b7ca42c99d01624125a33bb3.png">
There’s a lesson here: high <a href="https://coinmarketcap.com/academy/glossary/fully-diluted-value-fdv" rel="noopener noreferrer nofollow">FDV</a>, low float, and a clever proof system don't matter if nobody shows up to use the thing.
<h2 id="the-new-new-guard">The New New Guard</h2>
Which brings us to the projects that are building privacy as the foundation, rather than a bolt-on. The market here is, as usual, slow to update. But a wave of new entrants is beginning to make some noise.
Chief among these is <a href="https://coinmarketcap.com/currencies/octra/" rel="noopener noreferrer nofollow">Octra (OCT)</a>, a fully homomorphic encryption (FHE) L1, meaning computation runs directly on <a href="https://coinmarketcap.com/academy/glossary/encryption" rel="noopener noreferrer nofollow">encrypted</a> data without ever decrypting it. Its mainnet alpha launched in December 2025, and the <a href="https://coinmarketcap.com/academy/glossary/testnet" rel="noopener noreferrer nofollow">testnet</a> processed over 100 million transactions at a peak of 17,000 TPS.
Octra distinguishes itself from rivals by building its FHE from scratch rather than licensing it. It’s currently leading the FHE narrative with an up-and-right (so far) chart.
<a href="https://dex.coinmarketcap.com/token/base/0xd13ba0d625c04b8364de5e15e58bf2ebdda8dba3/" rel="noopener noreferrer nofollow">Veilnet (VEILNET)</a> takes a hybrid route, combining FHE and ZK to run encrypted computation <a href="https://coinmarketcap.com/academy/glossary/off-chain" rel="noopener noreferrer nofollow">off-chain</a> while ZK proofs verify it on-chain. It's pitched as "privacy without the regulatory risk."
The market noticed fast: after on-chain analysts flagged it as "insanely underpriced" at a $75,000 market cap, VEILNET rocketed past $1.6 million within days.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/4652913a31214b169133b332bdcc4fc9.png">
<a href="https://coinmarketcap.com/currencies/humanity-protocol/" rel="noopener noreferrer nofollow">Humanity Protocol (H)</a> has also been on an absolute tear, but it tackles privacy from a completely different part of the stack. It enables users to prove they are a unique human without exposing their data.
The project pairs palm-vein biometrics with zero-knowledge proofs, storing biometrics on-chain as encrypted proofs instead of raw images. It’s currently up almost 1,400% since its post-launch dip, making it one of this cycle’s best performers.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/438255c0b33c4665b47c33f97c71ad5d.png">

The throughline is what each generation chooses to hide. XMR obfuscates transactions; ZEC proves them valid without revealing details; meanwhile, the newest class encrypts the entire computation.
Each step moves privacy deeper into the stack. The future is clearly encrypted. The gap between what privacy is worth and what it costs is closing fast.
