ARCHITECTURE & SECURITY
Core Technical Capabilities We Deliver
We build enterprise-grade, privacy-preserving ranking systems that deliver verifiable fairness without exposing sensitive player data. Our solutions are production-ready, secure by design, and integrate seamlessly into your existing stack.
01
Zero-Knowledge Proof (ZKP) Integration
Implement zk-SNARKs or zk-STARKs to compute and verify player rankings off-chain, publishing only the final, immutable result on-chain. This ensures complete data privacy while maintaining cryptographic proof of correct computation.
100%
Data Privacy

Proof Systems
02
Secure Multi-Party Computation (MPC)
Deploy MPC protocols to allow multiple parties (e.g., game servers, validators) to jointly compute rankings over encrypted player data. No single entity ever sees the raw input, eliminating central points of failure and trust.
Threshold Cryptography
Security Model
No Single Point of Trust
Architecture
03
On-Chain Verifiability & Immutability
Anchor ranking results and their ZK proofs to a public blockchain (Ethereum, Polygon, Solana). This provides a tamper-proof, transparent, and universally verifiable ledger of all historical rankings, building trust with your player base.

Custom Ranking Algorithm Development
Design and implement bespoke Elo, Glicko-2, or TrueSkill algorithms tailored to your game's mechanics. We optimize for fairness, anti-sybil resistance, and dynamic skill assessment, then encrypt the logic for privacy-preserving execution.
