REP x World ID x Jolt ZK Proof Dashboard

What This Demo Shows

Zero-Knowledge Reputation

A 10,000-node synthetic reputation graph with 85K+ claims from 8 real-world data sources (banking, crypto wallets, social media, commerce). Every eligibility check, delegation, and routing decision is proven inside a RISC-V zkVM (Jolt) — the verifier learns the result but never sees the underlying data.

World ID Integration

2,162 humans (39%) have Worldcoin World ID verification. A Semaphore-style membership proof inside Jolt proves humanity without revealing identity. This Uniqueness claim adds ~100 trust points and can be the deciding factor between eligible and not eligible.

Proof Composition

Three independent proofs (eligibility, delegation, routing) are composed via shared Merkle roots — the same snapshot binds all three. An agent can only act if the principal is eligible, the delegation is valid, and the routing selects a real merchant. Tampering with any proof breaks the chain.

Adversarial Resilience

335 adversarial nodes across 8 attack types: Sybil clusters, stale identities, compromised agents, inflated scores, collusion rings. The system catches them through cross-context claim verification, freshness gates, and risk tiers — while preserving false positives (legitimate users who look suspicious).

Use Cases

🏦

Undercollateralized DeFi Lending

Prove creditworthiness from banking + wallet history without revealing balances

🤖

AI Agent Access Control

Agents prove their human principal is trustworthy via scoped delegation proofs

🌐

Sybil-Resistant Airdrops

World ID + cross-platform claims ensure one-human-one-allocation

🛡

Privacy-Preserving KYC

Prove you meet regulatory requirements without sharing personal data

🎯

Merchant Discovery

ZK routing proofs match users to merchants without revealing preferences

📊

Cross-Chain Reputation

Aggregate reputation from ETH, Solana, socials, and commerce in one proof

Why This Matters

Today, reputation is siloed, opaque, and non-portable. REP x Jolt proves that general-purpose zkVM (Jolt RISC-V) can compose multiple reputation proofs into a single verifiable pipeline — from World ID humanity check through eligibility scoring to merchant routing — all without revealing the underlying data. This is the infrastructure layer for privacy-preserving trust in the agent economy.

About This Demo & Where REP Is Heading

This demo

The data in this demo is synthetic — a 10K-node graph generated deterministically from a seed. Claims like "SpendBand", "WalletActivity", "SocialPresence" are simulated with realistic distributions, adversarial cohorts, and cross-context correlations.

But the ZK proofs are real. Every proof you see here is a genuine RISC-V execution inside Jolt zkVM — real Merkle trees, real SHA-256 hashing, real proof generation and verification. The circuit logic is production-grade.

REP at scale

In production, REP replaces synthetic data with real-world signals from multiple sources, all verified cryptographically:

zkTLS Twitter followers, GitHub commits, LinkedIn connections, Spotify listening — verified via TLS session proofs without API keys On-chain ETH/Solana wallet activity, DeFi positions, NFT holdings, transaction history — directly from blockchain state OpenBanking Income verification, spending patterns, credit indicators — via PSD2/Open Banking APIs with user consent World ID Proof of humanity via iris scan — Sybil resistance without identity disclosure Credentials Verifiable credentials, attestations, community vouches — portable trust from existing ecosystems AI / LLM Agent spending patterns, capability scores, tool usage history — reputation for the agent economy

The vision: portable, private, composable reputation

Collect

User connects data sources — zkTLS, wallets, banking, socials. Each produces a cryptographic claim.

Prove

Claims are composed into ZK proofs inside Jolt. The prover sees data; the verifier sees only the result.

Verify

Any protocol verifies the proof in milliseconds. On-chain, off-chain, cross-chain — same proof, same trust.

Access

Undercollateralized loans, agent permissions, Sybil-resistant airdrops, KYC-free compliance — all gated by proof, not identity.
