1. What Are We Building on Sapphire?
Confidential Peer Review & Agreement Protocol
We propose a privacy-first peer evaluation system built on Oasis Sapphire's confidential EVM. This module enables teams to exchange peer feedback, review contributions, and generate confidential agreements — all powered by trusted on-chain computation.
Key characteristics:
- Confidential smart contracts manage peer reviews and contribution agreements without public exposure of sensitive data.
- Controlled computation ensures review aggregation and algorithmic outputs (e.g., reputation scores, aggregated summaries) remain private and accessible only to authorized members.
- Modular architecture designed for future integration with ROFL-powered AI agents for deeper insight and coaching — though AI integration is out of scope for this application and planned later.
2. Core Features & Deliverables
Here are the foundational modules we will build on Sapphire in this grant:
- Confidential Peer Review Contract
- Enables encrypted submission of peer feedback.
- Ensures only authorized recipients (e.g., reviewees and designated managers) can decrypt content.
- Confidential Agreement Logic
- Facilitates private multi-party agreements, signatures, and acknowledgments (e.g., task agreements, team charters).
- Implements permissioned access and mutable consent states.
- Private Aggregation & Computation
- Computes group-level analytics (e.g., average feedback scores, consensus metrics) inside the Sapphire runtime.
- Outputs only aggregated, de-identified results to maintain confidentiality.
- Optional UX Primitives (Permissioned Identity)
- A minimal abstraction layer for user addresses, enabling privacy-preserving identity mapping (via ephemeral pseudonyms or commitment schemes), if supported by Sapphire—optional based on feasibility.
These modules directly address the gaps in current Arbitrum/EVM tooling (no built‑in confidentiality or private compute) by leveraging Sapphire’s secure compute for sensitive, human-centric processes.
