The venture firm a16z and entrepreneur Balaji Srinivasan have named privacy the crypto industry’s leading theme for 2026. Analysts at Galaxy Research forecast the sector’s market capitalisation could reach $100bn.
Together with the team behind the bitcoin mixer Mixer.Money, we examine what is driving this trend, the risks of blockchain transparency and the tools that can help protect privacy on the Bitcoin network.
Privacy as 2026’s defining trend
In January 2026, a16z crypto published its annual Big Ideas 2026 outlook. General partner Ali Yahya called privacy “the most important competitive advantage in the crypto industry”.
In his view, it is the one capability critically needed for global finance to migrate to blockchains—yet most existing networks lack it. For years it was treated as a secondary concern; now it can set a network apart from rivals.
Yahya highlights privacy’s network effects:
“Moving tokens is easy; moving secrets is hard. When moving between private and public zones, there is always a risk that observers of the network, the mempool, or the traffic will be able to identify you.”
This creates a “winner-takes-almost-all” dynamic. Once users join a private blockchain, they are less likely to leave it for fear of de-anonymisation.
“In public blockchains, it is easy for users to interact with one another even if they are on different networks. The choice of a specific blockchain is not essential here. In private networks it is different: after connecting to one blockchain, users switch to another much less often because it entails a risk of losing confidentiality. […] Given that privacy is critically important for most real-world use cases, the bulk of the crypto market may, over time, concentrate around a few private blockchains,” Yahya explains.
The former CTO of Coinbase and author of the Network State concept, Balaji Srinivasan, proposed dividing crypto into three eras:
- 2009–2017 — proving Bitcoin’s viability.
- 2017–2025 — programmability via Ethereum and DeFi.
- 2025–2030s — privacy based on technologies with zero-knowledge.
Others in the market echo privacy’s importance. Pantera Capital predicts the rise of Privacy-as-a-Service solutions for enterprise clients. Binance Research has included privacy among 12 key market themes this year.
Why privacy matters now
In Mixer.Money’s view, several forces are driving interest in privacy:
1. The physical safety of crypto investors is under threat. According to TRM Labs data, 2025 was a record year for so‑called wrench attacks—physical assaults on holders of digital assets.
On 19 January, Casa co-founder Jameson Lopp published a chart of wrench attacks. It shows a rising tally of incidents targeting crypto users. Lopp points to a particularly sharp jump in France since 2025.

2. The technology is ready for scale. By a16z’s forecast, by end‑2026 zkVM prover overheads could fall to roughly 10,000× from 1,000,000×. Vitalik Buterin introduced Kohaku, a toolkit to enhance privacy and security across the Ethereum ecosystem, and the Ethereum Foundation created a dedicated Privacy Cluster of 47 experts.
3. Institutions require confidentiality. Banks and large financial firms are entering crypto, but they are unwilling to use fully transparent public blockchains that risk exposing commercially sensitive data.
The real risks of public transactions
Without privacy tools, any sender or recipient of a transaction can see a wallet’s balance and trace flows—where funds came from and where they are going.
Centralised exchanges freeze funds when they detect links to suspicious addresses. Often the user does not even know they received “tainted” coins.
On the Bitcoin network, to enhance anonymity and reduce the risk of exchange blacklisting, users employ bitcoin mixers—longstanding tools for breaking the on‑chain link between the inputs and outputs of funds.
Services such as Mixer.Money use algorithms that conceal the very fact of mixing. In “Full anonymity” mode, a user receives an equivalent amount from investors on large exchanges—coins with an entirely different history.
For anonymisation, it is enough to go to the website, choose a mode, specify return addresses and send bitcoin. No registration is required. The service issues a guarantee letter with a PGP signature and offers a free test: when sending 0.001 BTC, the user receives it back without a fee.
Privacy as a standard
The market is moving toward a model where confidentiality is a baseline requirement rather than a feature. Matter Labs CEO Alex Gluchowski said the rise of privacy tools reflects not only retail demand but also institutional interest.
The expert distinguishes two kinds of privacy: cypherpunk, at the account level, and institutional, at the system level.
“Corporations need full control over their data flows, hiding them from everyone else,” he explained.
Institutional adoption supports a16z’s thesis: privacy creates a durable competitive edge. Blockchains with robust privacy tooling accrue network effects that rivals will struggle to replicate.
For individual bitcoin holders, privacy is not just about comfort but physical safety. Combining tools such as Silent Payments for receiving funds and bitcoin mixers to break history enables multilayer protection without sacrificing convenience.
“Privacy is the norm. A user does not have to know the history of every coin, just as he does not have to know the history of the cash in his wallet. Our task is to provide a tool that works here and now, until the privacy infrastructure becomes the industry standard,” they summarise at Mixer.Money.
