ZK-Powered Sybil-Resistant Protocol Design

We architect and develop custom protocols that use zero-knowledge proofs to verify unique personhood or credentials. Secure your airdrops, governance, and reward systems against Sybil attacks without collecting personal data.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that form the backbone of your dApp. Our development process ensures security-first design, gas optimization, and audit readiness from day one.

  • Token Systems: ERC-20, ERC-721, ERC-1155, and custom tokenomics.
  • DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, staking contracts.
  • Governance & DAOs: Voting mechanisms, treasury management, and upgradeable proxies.
  • Enterprise Logic: Custom business rules, access control, and multi-signature workflows.

We deliver battle-tested code with a 99.9% uptime SLA and comprehensive documentation, enabling your team to launch with confidence.

Our contracts are built on Solidity 0.8+ using OpenZeppelin libraries and follow industry-standard security patterns. Each project includes unit and integration testing, a technical specification document, and is structured for seamless future upgrades.

Our ZK Sybil-Resistance Protocol Capabilities

We architect and deploy production-ready, zero-knowledge-based sybil-resistance systems that protect your token distribution, governance, and incentive programs from manipulation, ensuring fair participation and accurate user attribution.

01

Custom ZK Attestation Systems

Design and implement bespoke zero-knowledge proof circuits for unique identity attestations. We deliver protocols that verify user uniqueness (e.g., one-person-one-vote, one-wallet-per-user) without exposing personal data, built with frameworks like Circom and Halo2.

On-Chain Reputation & Scoring

Develop sybil-resistant reputation graphs and scoring mechanisms. We integrate on-chain activity, social attestations, and off-chain signals to create tamper-proof user scores that drive fair airdrops, governance weight, and loyalty programs.

Gas-Optimized Verification

Deploy highly efficient verifier smart contracts that minimize gas costs for sybil-proof validation. Our Solidity implementations use optimal pairing curves and batch verification to keep per-user costs under $0.01 even at scale.

PROVEN FRAMEWORK

Our Development Methodology

Our systematic approach to ZK-powered protocol design ensures security, scalability, and rapid deployment. We deliver production-ready systems, not just proofs-of-concept.

01

Threat Modeling & Architecture

We begin with a comprehensive threat analysis to identify Sybil vectors and design a robust, modular protocol architecture. This upfront rigor prevents costly redesigns later.

Frequently Asked Questions

Get clear answers on our process, timelines, and technical approach for building sybil-resistant systems with zero-knowledge proofs.

Our engagement follows a structured 4-phase methodology: 1. Discovery & Scoping (1-2 weeks): We analyze your threat model and define protocol requirements. 2. Architecture & Design (2-3 weeks): We create the cryptographic scheme and system architecture. 3. Implementation & Audit (4-8 weeks): Our team builds and internally audits the protocol. 4. Deployment & Support: We assist with mainnet launch and provide 90 days of post-launch support. We start with a fixed-price discovery phase to ensure alignment before full project commitment.
