DELIVERABLES
Business Outcomes for Your Protocol
Our Proof-of-Identity consensus development delivers more than just code. We build the secure, scalable, and compliant identity layer that powers your protocol's core value proposition.
01
Secure Identity Layer
We develop custom on-chain identity registries and verification logic, enabling secure, non-transferable identity attestations as the foundation for your consensus. This prevents Sybil attacks and ensures one-person-one-vote integrity.

Regulatory Compliance by Design
Architected with compliance hooks for KYC/AML providers, our identity consensus systems integrate with verifiable credential standards (W3C VC) and privacy-preserving proofs (zk-SNARKs) to meet global regulatory requirements.

High-Throughput Consensus Engine
We implement optimized BFT-style consensus algorithms (e.g., Tendermint Core, HotStuff) tailored for identity-weighted voting, achieving sub-3-second finality and supporting thousands of identity-verified transactions per second.

Technical & Commercial Insights
Proof-of-Identity Consensus FAQ
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a Proof-of-Identity consensus development partner.
A complete Proof-of-Identity consensus layer, from architectural design to mainnet deployment, typically takes 6 to 12 weeks. This includes 2 weeks for requirements & threat modeling, 3-5 weeks for core protocol development and smart contract creation, 2 weeks for internal security audits and testing, and 1-3 weeks for client integration and final deployment. Complex integrations with existing KYC/AML systems or custom identity attestors can extend this timeline.
