Compliance-friendly tools are on the rise.

In the year 2025 will see crypto privacy come into focus as new technology clashes with regulators, a trend in 2026 where developers are pushing the envelope and legal battles are drawing to a close.

In the early days, Bitcoin (BTC) was often seen as an anonymous payment instrument despite its transparency. Since then, the introduction of onchain analytics and monitoring has made it even clearer that transparent blockchains are far from private.

This has led to an arms race between pro-privacy developers, onchain spying organizations and regulators, leading to high-profile legal cases. The developers of decentralized Ether (ETH) hybrid Tornado Cash are fighting over whether software development is a financial service, and the people behind Bitcoin non-custodian Samurai Violet were recently sentenced to prison in a US court.

Despite this, a privacy-focused development has emerged this year. Industry experts suggest that while the privacy tool stack will remain largely unchanged in 2025, those tools are expected to evolve in 2026 for a new generation of “pragmatic privacy,” ensuring privacy and compliance with sanctions.

How we sleep into available money.

Payment processors are able to clearly define the parties, products and services involved in transactions, allowing censorship. This is far from a theoretical risk, with major PC game distributor Steam and competitor Itch.io clearing adult content by 2025 after pressure from payment processors. Before that, the US Treasury In 2011, WikiLeaks was shut down by pay providers, despite declaring that it would not be sanctioned.

WikiLeaks turned to Bitcoin as an unfiltered currency. Bitcoin was born out of the same cypherpunk circles that saw the circulation of Timothy May – an influential engineer in the development of Bitcoin and founder of the cypherpunk mailing list – “Crypto Anarchist Manifesto.”

Since 1988, the document has defined encrypted exchanges that guarantee universal anonymity, freedom of speech and freedom of commerce.

Three secret privacy in 2026

One can think of crypto-privacy in three steps. At the protocol layer, Layer 2s (L2s) and privacy coins like Monero (XMR) use encryption, hedged pools, and custom transaction formats to hide who pays and how much.

At the user layer, privacy depends on the user's capabilities: wallet selection, address reuse, device footprints, network practices (VPN/Tor), privacy tools, and overall operational security (OpSec).

At the perimeter layer, fiat on- and off-ramps, such as crypto exchanges, banks, stragacoin issuers, and analytics firms that link blockchain activity to real identities, can usurp protocol privacy achieved at other layers.

Nathaniel Fried, co-founder and CEO of 0xBow – the company behind Ethereum-based onchain privacy tool Privacy Pools – told Cointelegraph that the perimeter layer and mostly fiat on and off ramps are major privacy bottlenecks. Such platforms verify deposits to comply with blockchain analytics services that often exclude funds from most privacy protection services, he said.

Zachary Williamson, founder and CEO of privacy-focused decentralized blockchain Aztec, told Cointelegraph that most privacy protections should be handled by users. “It is unreasonable to expect users to have a greater understanding of what information they are or are not transmitting,” he added. “This should be handled securely and automatically at the application layer.”

The new privacy tech stack

As discussed above, achieving privacy as a crypto user requires an approach that spans the protocol, user, and perimeter layers. Williamson acknowledges privacy pools as the only significant change in privacy tool offerings in 2025.

“The group is doing a great job of designing secure ways of trading,” he said. Williamson chose Anoncoin Zcash (ZEC) as the protocol layer recommendation for Aztech's mainnet launch.

Privacy pools, as suggested by Freed, are collective pools where users deposit and later withdraw their funds with zero-knowledge proof that their funds come from a “pure” subset of deposits. This allows for anonymity while ensuring sanctions compliance.

Still, proper usage is important and keeping assets in a pool for a certain amount of time helps ensure strong anonymity. Fred pointed out that returning to a deposit address does not improve one's privacy, and provided another example of misuse.

“Sometimes we see a certain amount of deposit for example 0.2439 ETH and immediately withdraw 0.02439, which definitely raises strong suspicions, but it is not 100% necessarily the same user.

Williamson and Fried both suggested defining NIM for network identity. NIM is a decentralized mixnet that cuts traffic into fixed-size, layered encrypted packets and masks traffic across multiple nodes with arbitrary delay and masking to overcome global traffic analysis rather than hiding IP addresses.

“While a centralized VPN can protect your IP address and connection from outside parties, you're simply putting your trust in the VPN provider, who can see both,” a Nim representative told Cointelegraph.

Instead, their system aims to prevent any network component from linking a user's IP address to a foreign address assigned to them. “You don't have to believe Nim, because Nim doesn't know,” they said.

Stronger metadata privacy and less dependency on a single company compared to regular VPNs. Still, it's slower and less mature than traditional VPNs, with critical issues recently announced in 2024. A NIM spokesperson indicated that the issues were discovered and resolved during a security audit, with another audit coming in 2026.

Williamson's recommended communications tool, Signal — a journalist favorite that stores no user data — was revealed in March to have been used by top US national security officials to launch attacks on the Houthis.

For documents, Fried recommends Fileverse: a decentralized, privacy-first end-to-end encrypted Google Workspace and Notion, an alternative that lets you collaborate on documents, spreadsheets, and files on-chain using decentralized storage and wallet-based access control. It was also recently praised by Ethereum co-founder Vitalik Buterin.

Barriers to development

Developing truly decentralized, trustless, and uncontrollable private systems is generally much more difficult than building centralized counterparts. Still, regulatory pressure, rather than technical difficulty, may be the biggest current obstacle to the growth of crypto privacy.

In the year On November 19, Keone Rodriguez and William Lonergan Hill, founders of Bitcoin's non-redeemable wallet and mixer Samurai wallet, were sentenced to four and five years in prison, respectively. They were convicted of conspiracy to conduct an unauthorized money transfer business and facilitating transactions involving the proceeds of crime.

The punishment came even though Zamora had no control over the assets. The prosecution argued that coordinating the transaction was a money transfer service, even though the money could not be controlled.

Other cases highlight that prosecutors will use any regulatory mechanism to determine responsibility. In the year In 2023, prosecutors argued that the developers of the previously approved Ethereum-based decentralized crypto mixer Tornado Cash “did not choose to implement know-your-customer or anti-fraud programs as required by law.”

In October, Tornado Cash co-founder Roman Storm asked decentralized finance developers, “How can you be sure you don't pay in fees?” [Department of Justice] As a money services business to build a non-custodial protocol?” Prosecutors said that any service should have been developed as a security service because it was charged with not implementing centralized control measures.

Eric Hill, head of legal at decentralized finance protocol Lido and current advisor to Ethereum's privacy protocol Railgun, told Cointelegraph that projects that rely on open-source technologies to protect against lawsuits in an unsecured and decentralized fashion “do not meet the definition of financial services.”

Hill suggested avoiding implementing central control, holding administrators accountable for protocol updates, profiting from transactions, and promoting sanctioned entities and users. They said that the service should be provided for public benefit.

“Total decentralization and loss of carpenter control are important design choices.”

Niko Demchuk, head of legal at crypto forensics firm AMLBot, told Cointelegraph that an unregulated wallet “generally does not qualify as a money transmitter simply because the device allows users to make transactions.” Still, he said, it's not as clear.

“Recent cases indicate that noncustodial services may be subject to questioning if they facilitate anonymous money transfers in connection with interstate or foreign commerce.”

“A decentralized entity or group has to properly structure itself no matter what governance protocol or how it's built,” crypto lawyer Cal Evans told Cointelegraph.

Demchuk added, “The level of decentralization required to protect builders from criminal liability is based on the practical control of an individual.”

Providing practical privacy

A crypto privacy trend that emerged in response to regulatory pressure and is expected to increase by 2026 is asset anonymity while ensuring compliance with fines. 0xBow's Fried “The realistic future of privacy is practical.”

“Privacy developers must take governments' privacy concerns seriously and publicly demonstrate that they comply with relevant laws and regulations,” he said. Still, Fred emphasized that “collecting users' personal information” is a “line we are not willing to cross.”

Noting that Aztec is moving in the same direction, Williamson says he believes in the vision that privacy pools are building. “I think it's important to enable apps that users can use with confidence that their participation won't help bad actors,” he said.

Aztec is one of Ethereum's most decentralized L2s and a network approaching the most private mainnet deployment possible. Like privacy pools, the network follows a functional privacy design principle.

Aztech plans to provide privacy by default while offering private sanctions checks with anonymous authentication and optional disclosure features for users who want to audit.
