Replacing Trust with Proofs

Skye — Sun, 08 Mar 2026 12:40:48 +0000

ZKCG takes a different approach.

Instead of trusting an oracle, we verify the computation itself using zero-knowledge proofs.

Off-chain computation
        ↓
ZK proof generated
        ↓
Verifier checks proof

Now the verifier only needs to check that:

the proof is valid

the computation followed the defined constraints

No trusted signer required.

The Problem with Oracles

Skye — Sun, 08 Mar 2026 12:27:47 +0000

Many systems rely on trusted entities to attest to off-chain data:

Examples include:

DeFi price feeds

computation verification

reputation or credit scoring systems

data aggregation

The problem is simple:

You must trust the oracle.

If the oracle lies, the system fails.

Replacing Trusted Oracles with Zero-Knowledge Proofs in Rust

Skye — Sun, 08 Mar 2026 12:26:33 +0000

Zero-knowledge proofs are increasingly used to verify computations without revealing the underlying data. Most systems today still rely on trusted oracle signatures to confirm off-chain results.

But signatures introduce a trust assumption.

What if instead we could verify the computation itself?

That’s the idea behind ZKCG (Zero Knowledge Credit Graph), an open-source Rust framework for generating and verifying proofs of off-chain computation.
