DELIVERABLES
Business Outcomes: Governance You Can Trust
Our sybil-resistant identity and signer designs deliver measurable security and operational improvements, enabling you to launch and scale governance with confidence.
01
Sybil-Resistant On-Chain Voting
Implement token-gated governance with identity verification to prevent vote manipulation. We design custom mechanisms using soulbound tokens and proof-of-personhood integrations to ensure one-human-one-vote integrity.

Architecture Comparison
Custom Identity Layer vs. Basic Token Voting
A technical breakdown of Sybil-resistant governance models, comparing the limitations of standard token voting with the enhanced security and functionality of a custom identity layer.
| Governance Feature | Basic Token Voting | Custom Identity Layer |
|---|---|---|
Sybil Resistance | ||
Delegated Voting | Protocol-native only | Custom delegation logic |
Multi-Chain Identity | ||
Gasless Voting | Depends on protocol | Built-in meta-transactions |
Compliance & KYC Integration | Not possible | Optional modular add-on |
Time to Implement | 1-2 weeks (integrate) | 4-8 weeks (design & build) |
Attack Surface | High (whale dominance) | Low (verified participants) |
Typical Cost | $0 (protocol tooling) | $50K - $150K+ (custom build) |

Frequently Asked Questions
Get clear answers on our process, security, and outcomes for building robust, Sybil-resistant identity systems.
Our process follows a structured 4-phase methodology: 1. Discovery & Design (1-2 weeks): We analyze your use case, threat model, and design the identity architecture. 2. Core Development (3-6 weeks): We build the smart contracts (e.g., Semaphore, RLN, custom ZK-circuits) and off-chain signer services. 3. Security & Audit (2-3 weeks): Code undergoes internal review and a formal audit by a partner firm like Spearbit or Code4rena. 4. Deployment & Integration (1-2 weeks): We deploy to mainnet/testnet and integrate with your frontend. A typical end-to-end project takes 8-12 weeks.
