As Web3 evolves, its focus is shifting beyond decentralization alone. The next layer being actively built is privacy — especially as financial use cases like stablecoins, DeFi, and real-world assets move on-chain.
In the latest episode of the DePINed Podcast, Tom Trowbridge speaks with Francis Otshudi, CTO of iExec, about why privacy is no longer optional. As more institutions explore blockchain infrastructure, the need to protect sensitive data and transaction details becomes essential.
Without confidentiality, many real-world use cases simply cannot exist on public infrastructure.
From Trust to Privacy in Decentralized Systems
One of the key ideas discussed in the episode is the distinction between trust and privacy.
In traditional systems, users rely on centralized providers to behave correctly. Platforms like cloud services operate on the assumption that users trust them not to misuse data.
In decentralized environments, that assumption breaks down. When computation happens across unknown machines, trust alone is not enough. Systems must guarantee that data remains private regardless of who processes it.
Francis explains that while trust can be achieved through mechanisms like replication and consensus, privacy requires a different approach — one that ensures data is never exposed in the first place.
Ownership as the Core Problem of the Digital Economy
Beyond privacy, iExec frames the problem at a deeper level: ownership.
In today’s digital economy, users constantly generate data — but control over that data is often lost once it is shared with centralized platforms. This creates a fundamental gap between creating digital assets and actually owning them.
iExec’s approach focuses on enabling users and organizations to:
- retain ownership of their data
- control access through programmable rules
- extract value from data without revealing it
This shift changes how data can be used. Instead of transferring ownership, users can allow computation to happen on their data while keeping it private.
How iExec Uses Trusted Execution Environments
At the technical level, iExec builds its solution around Trusted Execution Environments (TEEs).
These environments allow computations to run in secure enclaves where data remains encrypted and inaccessible, even to the machine performing the computation.
Instead of distributing workloads across multiple nodes to establish trust, iExec uses TEEs to ensure both trust and privacy within a single execution environment.
This design enables new types of applications:
- processing encrypted data
- running AI models without exposing training data
- executing financial strategies without revealing algorithms
The result is a system where data can be used without being disclosed.
A Shift in DePIN
A major theme in the conversation is the evolution from infrastructure to usable products.
Like many early DePIN projects, iExec initially focused on building a powerful protocol. However, real adoption required more than just infrastructure — it required simplicity.
Francis highlights how early versions of the platform were too complex for users, involving marketplace mechanics and manual coordination between compute, data, and applications.
The shift came when iExec began abstracting this complexity:
- simplifying developer workflows
- creating accessible tooling
- focusing on user experience instead of protocol mechanics
This move toward productization significantly improved how the platform is perceived and used.
Real Use Cases: DeFi, Stablecoins and RWAs
Today, iExec is focusing on some of the most promising areas in Web3:
Confidential stablecoins
Transactions can remain verifiable while hiding sensitive details like transferred amounts.
Privacy-preserving DeFi
Trading strategies and financial operations can be executed without exposing underlying logic.
Privacy-enabled KYC
Users can prove identity or compliance without revealing personal data.
RWA infrastructure
Institutions can securely connect traditional systems with blockchain environments.
These use cases highlight a broader trend: privacy is becoming a prerequisite for institutional participation in Web3.
Why Web3-Native Users Come First
Interestingly, iExec’s go-to-market strategy has focused on Web3-native users rather than traditional enterprises.
While the company initially explored enterprise adoption, they found that many traditional organizations were not ready to move into production with decentralized infrastructure.
In contrast, Web3 builders immediately understood the value proposition and were more willing to experiment.
Now, as institutions begin moving on-chain, the timing is shifting. The infrastructure built for early adopters may soon become critical for a much broader audience.
Token Economics and the Reality of Scale
The iExec ecosystem is powered by its native RLC token, which is used to:
- pay for compute resources
- reward infrastructure providers
- monetize applications and datasets
However, the discussion also highlights a common challenge across DePIN projects: token demand is directly tied to real usage.
Without meaningful adoption, token economies remain theoretical.
iExec has introduced mechanisms like vouchers to address pricing volatility, allowing users to reserve capacity with predictable costs. Still, the long-term success of the model depends on scaling real-world use cases.
What Comes Next for Privacy Infrastructure
Looking ahead, iExec is positioning itself at the intersection of privacy and on-chain finance.
As stablecoins, DeFi platforms, and tokenized assets grow, the demand for confidentiality will likely increase. Institutions entering the space will require both transparency for compliance and privacy for competitive and regulatory reasons.
The key question is no longer whether Web3 can support decentralized infrastructure — but whether it can support it in a way that preserves ownership and confidentiality.
Projects like iExec are working to make that possible.
