Interfold Use Cases: Markets, Voting, and AI Coordination
A practical map of how Interfold applies when markets, voting systems, and AI workflows need shared, verifiable outcomes from private inputs.
The Interfold is a distributed network for confidential coordination. It enables independent parties to produce shared, verifiable outcomes from private inputs without pooling data or delegating execution authority to a single operator.
That structure applies wherever private inputs need to become a result others can rely on:
A bid becomes a clearing price.
A vote becomes a tally.
A private dataset contributes to a model evaluation or shared signal.
The domains differ, but the pattern is the same:
This primer looks at three clear surfaces where that pattern appears in practice: markets, voting, and AI coordination. They are not the only use cases, but they make the structure easy to see.
Markets: private inputs, fairer outcomes
Markets often depend on information that should not be visible before the outcome is finalized.
That includes:
- sealed-bid auctions
- confidential pricing
- allocation mechanisms
- market-clearing processes
When bids, positions, or allocation signals are visible too early, visibility becomes part of the game: Participants can adapt, copy, front-run, or extract strategic advantage. If one operator sees everything, that operator becomes structurally privileged.
Interfold enables private bids or signals to contribute to a winning bid, clearing price, or allocation decision.
The result can be shared, while the positions behind it remain private.
Voting: private choices, verifiable results
Voting is one of the clearest examples of confidential coordination.
A secret ballot is not useful because votes stay hidden forever. It is useful because private choices become a legitimate public result.
The challenge is preserving both sides:
- individual choices should remain private
- the final result should be public and verifiable
If votes are public, participants can be pressured, punished, or bought. If tallying is centralized, legitimacy depends on the counter.
Interfold enables private choices to produce a verifiable result without exposing individual votes or relying on one tallying authority.
CRISP, Interfold’s reference implementation for coercion-resistant impartial selection, demonstrates this pattern for secret ballots and selection mechanisms. It sits in a broader lineage of private voting and anti-collusion research, including MACI, while applying the Interfold model: private choices, verifiable outcomes, and no single tallying authority.
AI coordination: private data, shared evaluation
AI coordination often depends on data that cannot simply be exposed, transferred, or pooled.
A foundation model may need to be evaluated against private institutional datasets. A group of firms may need to produce an aggregate risk signal without revealing portfolios. Multiple labs may need to contribute benchmark results without exposing the underlying test sets.
In each case, the goal is not to centralize the raw data, but to produce a shared result:
- a score
- a metric
- a comparison
- a signal
- an evaluation
Interfold enables private inputs from multiple parties to participate in a defined computation without pooling datasets or giving one operator control over the process.
A model can be evaluated against private data. A benchmark can be produced across separate institutions. A risk signal can be shared without exposing the records behind it.
The underlying data remains private, while the result becomes verifiable.
The common structure
Markets, voting, and AI coordination are different kinds of systems.
One clears prices.
One counts choices.
One produces evaluations, benchmarks, metrics, or shared signals.
But each coordination type depends on the same underlying structure: private inputs must be brought into a defined process, computed correctly, and released as a result others can verify.
That is the coordination problem Interfold is built for.
The important question is not only whether the inputs stay private. It is whether the process that turns those inputs into a shared outcome depends on a single point of control.
Many parties.
One result.
No single point of execution control.
