PRIVATE DATA INFRASTRUCTURE
Core Architectural Capabilities
We architect secure, scalable, and compliant private data layers tailored to your application chain's specific consensus, state, and regulatory requirements.
01
Custom State Encryption & Access Control
Design and implement application-specific encryption schemes (ZKPs, FHE, MPC) for on-chain state. We build granular, programmable access policies that integrate natively with your chain's validator set and governance model.

METHODOLOGY
Our Design & Delivery Process
A structured, security-first approach to designing and implementing private data layers for your application-specific blockchain. We deliver production-ready protocols with clear SLAs.
01
Architecture & Threat Modeling
We begin with a deep technical assessment of your AppChain's data flow, identifying sensitive data points and modeling potential attack vectors. This ensures the storage protocol is designed with security as the foundation, not an afterthought.

Protocol Specification & Design
We produce a formal technical specification for your private storage protocol, detailing encryption schemes (e.g., ZK-SNARKs, FHE), data sharding logic, access control models, and integration points with your chain's consensus.

Private Storage Protocol FAQs
Get clear answers on our process, security, and outcomes for designing and deploying custom private storage protocols for your AppChain.
Our process follows a structured 4-phase approach: 1. Discovery & Design (1-2 weeks): We analyze your AppChain's data model, privacy requirements, and threat model. 2. Protocol Architecture (2-3 weeks): We design the cryptographic scheme (e.g., ZK-SNARKs, FHE, TEEs) and on/off-chain data flow. 3. Implementation & Audit (3-5 weeks): Our team builds and integrates the protocol, followed by an internal security audit. 4. Deployment & Handoff (1 week): We deploy to your testnet/mainnet and provide full documentation. We provide weekly syncs and a dedicated technical lead.
