EXPERTISE IN ACTION
Architectural Capabilities We Deliver
We architect and implement secure, scalable decentralized messaging protocols that put user sovereignty first. Our solutions are built for production, not just proof-of-concept.
02
End-to-End Encrypted Messaging
Design and deploy protocols using modern cryptographic primitives (X25519, ChaCha20-Poly1305) for peer-to-peer encryption, ensuring only intended recipients can read messages.
03
Decentralized Message Routing & Storage
Architect resilient routing layers using libp2p or similar P2P stacks, with optional decentralized storage solutions (IPFS, Arweave) for persistent, censorship-resistant message history.
04
Protocol Design & Specification
Create formal protocol specifications and reference implementations for interoperable, open-standard messaging that avoids vendor lock-in and fosters ecosystem growth.
05
Security Audits & Formal Verification
Deliver protocol and smart contract security through third-party audits (e.g., Trail of Bits, Quantstamp) and formal verification tools to eliminate critical vulnerabilities.
06
Scalability & Interoperability Architecture
Design for high-throughput messaging with layer-2 solutions and cross-chain interoperability, enabling seamless communication across different blockchain ecosystems.

Strategic Infrastructure Decision
Build vs. Buy: Custom DID Protocol vs. Traditional & Web2 Messaging
A technical and economic comparison of developing a custom Decentralized Identity (DID) messaging protocol in-house versus partnering with Chainscore Labs for a production-ready solution.
| Key Factor | Build In-House | Traditional Web2 APIs | Chainscore Custom DID Protocol |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $250K - $750K+ | $10K - $50K (API fees) | $80K - $200K |
Data Ownership & Portability | Full (Your protocol) | None (Vendor lock-in) | Full (Your audited protocol) |
End-to-End Encryption | Custom implementation risk | Vendor-dependent | Built-in with Zero-Knowledge proofs |
Interoperability (W3C DID, VC) | Complex custom integration | Limited or none | Pre-built for Ethereum, Polygon, Solana |
Compliance (GDPR Right to Erasure) | High engineering burden | Manual, opaque processes | Architected for selective data deletion |
Recurring Infrastructure Cost | $50K - $150K/year (devops, nodes) | Per-message fees + platform costs | Optional SLA from $30K/year |
Protocol Security & Audit | High risk; requires external audit ($50K+) | Vendor's responsibility | Delivered with comprehensive audit report |
Team Requirement | 3-5 senior blockchain engineers | 1-2 integration developers | Your product team + our specialists |

For CTOs and Product Leaders
Decentralized Identity Messaging: Key Questions
Get clear, technical answers to the most common questions about building a secure, scalable decentralized identity messaging protocol.
We follow a structured 4-phase delivery model: Discovery & Design (1 week), Core Protocol Development (2-3 weeks), Security Audit & Testing (1-2 weeks), and Deployment & Integration (1 week). A standard DID-based messaging system with basic features (peer-to-peer, end-to-end encryption, selective disclosure) typically deploys in 4-6 weeks. Complex integrations (e.g., with existing SSO, multi-chain identity resolvers) may extend to 8-10 weeks.
