PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to building and deploying your privacy-preserving eBook platform. We deliver production-ready systems with clear milestones and guaranteed outcomes.
01
Architecture & Zero-Knowledge Design
We design a custom architecture integrating ZK-SNARKs (e.g., Circom) or ZK-STARKs for anonymous ownership proofs. This ensures user reading history and library contents remain private while enabling verifiable on-chain claims.

ZK Framework
2-3 weeks
Design Phase
02
Smart Contract Development & Audit
Development of core contracts for anonymous minting, ownership transfers, and royalty distribution using Solidity 0.8+ with OpenZeppelin. Includes a mandatory pre-deployment audit by a third-party security firm.

Frontend & SDK Integration
Build a seamless user interface (React/Next.js) with integrated wallet connectivity (WalletConnect, MetaMask) and a dedicated SDK. This SDK handles ZK proof generation client-side for optimal privacy and user experience.

Custom Blockchain Development
End-to-end development of custom blockchains, dApps, and smart contracts tailored to your business logic.
We architect and deploy bespoke blockchain solutions from the ground up. Our full-cycle development includes consensus design, node infrastructure, and core protocol implementation for both public and private networks.
- Layer 1 & 2 Development: Build high-throughput chains using
Substrate,Cosmos SDK, or customEVMrollups. - Smart Contract Suites: Production-grade
Solidity/Rustcontracts with formal verification and gas optimization. - Full-Stack dApps: Integrated frontends (
React/Next.js) with secure wallet connectivity and real-time indexers.
Deliver a market-ready, audited mainnet in 8-12 weeks, not months. We handle the entire stack so you can focus on product strategy.

Frequently Asked Questions
Get clear answers on how we build anonymous, on-chain ownership systems for digital content.
We implement a multi-layered privacy architecture. This includes zero-knowledge proofs (ZKPs) via Circom/SnarkJS to verify ownership without revealing wallet addresses, Semaphore for anonymous signaling, and stealth address systems for minting and transfers. All data is stored on-chain in encrypted form, with decryption keys held only by the verified owner.
