Why Real-World Assets (RWA) Can’t Scale Without a Blockchain Privacy Layer

After way too many calls, CoFHE cups and surveys with RWA teams, funds, and infrastructure builders- one thing became inevitably clear: tokenization works, transparency doesn’t. In Episode 1, we yapped about what 230+ hours of customer discovery taught us about who actually needs privacy and why. This time, we address the elephant in the room: Real World Assets (RWAs).

Every third tweet on the timeline unironically calls RWAs crypto’s “next big frontier”.

What we learned says otherwise:

RWAs aren’t blocked by regulation or lack of demand.

They’re blocked by exposure.

RWAs Aren’t It

From the outside, RWAs look like a natural fit for blockchains. You get programmable settlement that removes manual reconciliation, global liquidity that connects previously siloed markets, and composable financial primitives that let you build on top of tokenized assets.

But RWAs don’t exist in a vacuum. They are inherently institutional.

Real estate, treasuries, credit, private equity, invoices- these assets are issued, managed, and distributed by institutions that operate under strict regulatory, reputational, and fiduciary constraints. That means RWAs don’t just inherit blockchain properties; they inherit institutional requirements.

This is why most serious RWA deployments today look the same. They’re either partially onchain or heavily permissioned, restricted to a small circle of known counterparties. Many never move past pilot stages, not because demand disappears, but because scaling exposes information institutions cannot afford to leak.

When we asked teams why pilots stall, the answer wasn’t regulatory uncertainty or missing infrastructure.

It was this:

Real Finance Left the “Transparency” Group Chat

For institutions, transparency isn’t a virtue - it’s a liability.

Public blockchains expose investor identities, position sizes, pricing logic, capital flows, liquidation thresholds, and allocation strategies by default. For institutional actors, this creates immediate risks: competitive, legal, and reputational.

In traditional finance, none of this information is public. Not because it’s illicit, but because markets don’t function when every move is observable.

A fund doesn’t want competitors reverse-engineering its positions. An issuer doesn’t want pricing logic arbitraged in real time. A borrower doesn’t want refinancing negotiations front-run. And regulators don’t require public disclosure of sensitive deal terms- they require controlled disclosure.

This is the missing link in RWA adoption: institutions need privacy to participate, and RWAs can’t scale without institutions.

The Counterintuitive Insight: RWAs Don’t Need Anonymity

One of the biggest misconceptions we encountered is that RWAs require anonymity; they don’t.

What institutions consistently asked for was confidentiality, where identities are known to regulators but hidden from the public, deal terms are enforceable onchain yet unreadable by competitors, and risk logic is verifiable without exposing its inputs. This distinction matters, because privacy in RWAs is about selective disclosure and the ability to reveal the right information to the right parties, and nothing more.

Privacy, in this context, is what allows regulated capital to operate on public blockchains at all.

Why Current RWA Stacks Stall

Most RWA implementations today fall into one of two buckets:

1. Transparent Chains + Offchain Logic

Transparent chains expose every transaction, balance, and business logic decision to anyone running a node. For RWA applications, this creates immediate compliance nightmares with disputes arising, scale increasing, or trust assumptions getting stress-tested. The blockchain becomes an expensive database rather than a trust-minimizing system - you get the overhead without the benefits. When conflicts need resolution or compliance verification, you're back to traditional legal frameworks, manual oversight, and trusted intermediaries. Token holders discover they don't own programmable assets; they own claims dependent on offchain systems they can't verify or control.

2. Permissioned Systems with Limited Composability

Permissioned systems are compliant but siloed, safe but closed. You solve the privacy problem by controlling who gets access, but you sacrifice the composability that makes blockchain valuable. These systems limit liquidity because assets can't flow freely between protocols. They constrain integration because every connection requires explicit partnerships and API agreements. Most importantly, they kill innovation because developers can't build on top of existing protocols without permission from gatekeepers.

In both cases, the root issue is the same: there's no way to compute on sensitive data without revealing it. You can either expose everything and break compliance, or hide everything and break composability. This fundamental limitation is why RWA adoption stalls at the proof-of-concept stage - existing blockchain architectures force you to choose between transparency and privacy.

Encrypted Compute Cooked Here

Fully Homomorphic Encryption (FHE) changes the design space by introducing programmable confidentiality on public blockchains.

The most straightforward and foundational use case is also the most important one: confidential RWAs as a primitive.

Tokenized assets where ownership, balances, terms, and eligibility are enforced onchain without broadcasting sensitive data. Once this building block exists, more complex RWA patterns become possible:

• Confidential RWA issuance, where asset terms, yields, and vesting schedules are encrypted by default
• Onchain KYC / whitelist verification, where eligibility is proven without exposing identity or jurisdiction publicly
• Onchain credit scoring and tiered access, where users participate in different pools or tranches based on encrypted credit attributes
• Sealed-bid auctions for tokenized assets, enabling fair price discovery without bid leakage
• Private RWA-backed lending, where loan terms and liquidation thresholds aren’t visible to arbitrageurs
• Programmable compliance, where regulatory rules execute on encrypted data with selective auditability

The common thread is simple: rules execute onchain, outcomes are verifiable, but sensitive inputs remain confidential. This mirrors how real financial systems operate today- except now enforcement is cryptographic rather than institutional.

Why RWAs Are the Gateway to Institutional DeFi

RWAs are the anchor where compliance matters, reputational risk is real, and capital sizes change the threat model entirely.

Most DeFi ecosytems operate in relatively consequence-free environments. If a yield farming experiment fails, you lose speculative capital. If RWA tokenization dumps, you're facing SEC enforcement, investor lawsuits, and reputational damage that takes decades to repair. The stakes force you to solve the hard problems that crypto has been oversighting.

If blockchains can support RWAs properly - with confidentiality and auditability - the same infrastructure naturally extends to treasury management, OTC settlement, private payments, and institutional liquidity provisioning. The technical requirements are identical: encrypted computation, selective disclosure, regulatory compliance, and verifiable audit trails without exposing sensitive data.

In that sense, RWAs aren't the end goal. They're the proof point. Solve confidential tokenization of real estate, and you've built the foundation for institutional bond trading. Handle regulatory compliance for tokenized commodities, and you can support private stablecoin settlements. Provide audit trails for asset managers without leaking strategies, and you've unlocked the infrastructure that brings trillions in institutional capital onchain.

We Solved Tokenization, Now What?

After dozens of RWA-focused conversations, one conclusion stands out:

Tokenization is solved.

Settlement is solved.

What’s missing is a way to operate without leaking.

This exposure problem constrains RWAs more than regulation does. Blockchain's transparency makes it trustless and verifiable, but also unusable for applications where confidentiality is commercially essential or legally required. Until blockchains can support encrypted execution as a first-class primitive, RWAs will remain limited by what institutions are willing to reveal, not what they're allowed to do.

What This Means for Builders

If you’re building in the RWA space, here’s what we’ve learned: start with confidentiality before you even think about yield, because institutions worry far more about data leakage than APY. Design for selective disclosure, since regulators and counterparties don’t need or want the same level of visibility. Avoid offchain enforcement wherever possible, because every manual step quietly reintroduces trust assumptions. And above all, treat privacy as core infrastructure, not a feature you toggle on later.

Before you Log Off

RWAs don’t need new chains, they need chains that understand how real markets work.

Privacy, specifically encrypted computation, is what bridges that gap.

In the next episode of Privacy PMF Stories, we’ll dive into one of the most concrete impact zones emerging from our research: private payments and stablecoin rails, and why they may become the fastest path to mainstream adoption.

This is Episode 2 of Privacy PMF Stories where we share what we’re learning about building privacy infrastructure people can actually use.
