ZK-POWERED VERIFICATION
Core Circuit Capabilities We Deliver
Our custom-built zk-SNARK circuits provide the cryptographic backbone for secure, scalable, and cost-efficient decentralized storage proofs. We translate complex verification logic into optimized circuits that deliver tangible business results.
01
Proof-of-Storage Circuit Design
We architect custom zk-SNARK circuits that cryptographically verify data availability and integrity on decentralized storage networks like Filecoin and Arweave. This enables you to prove data is stored without revealing the data itself, ensuring privacy and reducing on-chain verification costs by over 90%.

02
Multi-Protocol Proof Aggregation
Our circuits aggregate storage proofs from multiple protocols (e.g., Filecoin's PoRep, Arweave's PoA) into a single, verifiable claim. This simplifies your application logic, reduces gas fees for on-chain settlement, and provides a unified trust layer for cross-chain data verification.

PROVEN METHODOLOGY
Our ZK Circuit Development Process
We deliver production-ready, verifiable storage proofs through a rigorous, four-phase development lifecycle designed for security, auditability, and seamless integration.
01
1. Architecture & Specification
We translate your storage logic (e.g., IPFS, Filecoin, Arweave) into a formal ZK circuit specification. This includes defining constraints, selecting the optimal proving system (Groth16, Plonk, Halo2), and planning for gas-efficient on-chain verification.

2. Circuit Implementation & Optimization
Our engineers write and optimize the circuit logic in Circom, Noir, or Halo2. We focus on minimizing constraint count and prover time, implementing custom gates where necessary, and ensuring compatibility with your chosen proving backend.

Frequently Asked Questions
Get clear answers on our development process, security, and delivery for custom zero-knowledge circuits that prove data integrity on decentralized storage networks.
A standard circuit for a specific storage proof (e.g., proving a file is stored on Filecoin or Arweave) typically takes 4-6 weeks from specification to production-ready audit. Complex multi-protocol proofs or novel cryptographic constructions can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones during the scoping phase.
