$WAL People talk about privacy like it’s a switch. Flip it on when you want protection, flip it off when regulators show up. That framing misses the point entirely.
The question that actually matters is much more ordinary, and honestly more uncomfortable: why does moving money inside compliant systems still feel like oversharing? Not illegal behavior. Not sketchy activity. Just normal business that ends up visible to far more people and systems than anyone really intended. Users feel it. Builders run into it. Institutions tolerate it because fixing it seems harder than living with it. Even regulators seem aware of it, even if they rarely say it out loud.
This problem exists because regulated finance grew up equating visibility with control. If everything can be seen, then everything feels manageable. That logic worked when systems were slow, centralized, and mostly closed. It feels much shakier in a world where transactions are automated, composable, and global by default.
Most current approaches try to patch the issue by carving out exceptions. You get privacy if you’re small enough, slow enough, or boxed into a very specific sandbox. Everyone else operates in systems where transparency is total, permanent, and indiscriminate. On paper, that sounds orderly. In practice, it creates friction everywhere.
For users, it means everyday financial actions leave detailed trails that go far beyond what’s actually needed for tax, audit, or enforcement. Not because someone is actively watching, but because the system exposes everything by default. For builders, it means compliance logic lives outside the protocol, bolted on through reporting tools, permissions, and legal processes that start to crack the moment software scales. For institutions, it often means choosing between efficiency and reputational risk, because infrastructure-level transparency doesn’t distinguish between legitimate oversight and competitive intelligence.
Regulators aren’t immune to this either. When everything is visible, enforcement gets noisy and reactive. Investigations rely on scraping and reconstruction rather than structured access to what actually matters. Too much data ends up becoming its own kind of opacity.
This is where many privacy solutions fall short. They treat privacy as a feature instead of a property of the system. Certain transactions are hidden. Certain fields are encrypted. Selective disclosure is layered on top of architectures that were never built for discretion in the first place. Technically, it works. Socially and legally, it’s fragile.
The deeper issue is that regulated finance doesn’t actually need maximum transparency. It needs accountable opacity. The ability to prove compliance without exposing everything else. The ability to store data without broadcasting it. The ability to settle value without turning every participant into a permanent public record.
That’s why infrastructure design matters more than narratives. Not as a showcase for cryptography, but as a place where human behavior, legal obligations, and cost structures collide. Systems don’t usually fail because they lack features. They fail because they force people to behave in ways that don’t make sense.
Take data storage. Financial institutions generate massive amounts of sensitive data that must be retained, accessed, and audited. Today, most of it lives in centralized systems trusted largely because they’re familiar. Breaches happen. Access controls sprawl. Compliance turns into paperwork instead of a systemic guarantee. Decentralization promises resilience, but without privacy baked in, it just moves the problem into public view.
This is why infrastructure projects like @Walrus 🦭/acc are interesting in a very unglamorous way. Not because they shout about privacy, but because they start from a quieter assumption: storage itself shouldn’t be implicitly public. Distributing data through techniques like erasure coding and blob storage isn’t about secrecy for its own sake. It’s about reducing unnecessary exposure while keeping data available and verifiable.
Running on Sui adds another practical layer. Throughput and programmability matter, but what matters more is that the base system doesn’t force every application into the same transparency model. If infrastructure assumes privacy is an exception, every app becomes an exercise in exception handling.
From a regulatory perspective, privacy by design is often easier to reason about than privacy by permission. If sensitive data isn’t globally accessible by default, regulators can define access paths that are deliberate and auditable. That’s closer to how oversight already works. Regulators don’t sit in trading rooms watching every transaction in real time. They request records. They audit selectively. They investigate when thresholds are crossed.
Costs matter too. Public transparency is expensive in ways people don’t always notice. Indexing, monitoring, compliance tooling, and legal review all scale with exposure. When everything is visible, everything needs to be watched. That turns into an arms race of analytics and surveillance that benefits almost no one.
There’s also a human dimension that rarely makes it into technical docs. People behave differently when every action is permanently observable. Institutions become overly cautious. Builders avoid regulated spaces because mistakes are public and irreversible. Users self-censor financial behavior in ways that distort markets and reduce inclusion.
Privacy by exception tries to manage this with rules. Privacy by design manages it with defaults. That difference is subtle, but it matters. One relies on constant enforcement. The other relies on structure.
None of this guarantees success. Privacy-first infrastructure can fail in very ordinary ways. If access controls aren’t clear, regulators won’t trust it. If integration costs are high, institutions won’t adopt it. If performance degrades under real load, builders will route around it. If governance is messy, privacy becomes a liability instead of a safeguard.
The skepticism is fair. We’ve seen neutrality turn into complexity. We’ve seen compliance tooling become chokepoints. We’ve seen privacy narratives collapse because they never lined up with legal reality.
The more realistic path is quieter. Infrastructure that treats privacy as normal, not special. Systems where data minimization is the baseline, not a feature request. Where compliance is something you can prove without explaining yourself to everyone, all the time.
Who actually uses that? Probably not speculators chasing novelty. More likely institutions handling sensitive data they’re legally required to protect. Builders who want to operate in regulated environments without turning their apps into surveillance machines. Regulators who would rather have structured access than uncontrolled visibility, even if they’re cautious about saying it.
Why might it work? Because it aligns incentives instead of fighting them. When privacy is built in, it reduces cost, risk, and noise. Compliance becomes functional instead of performative.
What makes it fail is treating privacy as ideology instead of infrastructure. Ignoring regulators instead of designing around real constraints. Assuming cryptography alone can replace governance, law, and human behavior.
The takeaway isn’t that regulated finance needs more secrecy. It needs better boundaries. Privacy by design isn’t about hiding. It’s about knowing exactly who needs to see what, and why. Systems that get that right won’t feel revolutionary. They’ll feel boring, dependable, and slightly invisible. That’s usually how trust actually gets built.
