🪶 Trust Capsule

A Verifiable Trust Protocol for the New Era of Digital Relationships

Trust Capsule is an experimental protocol developed to record, verify, and protect digital interactions between agents, humans, and automated systems on Web3. Its function is simple and essential: to transform trust into a verifiable asset.

---

🌐 Overview

Trust Capsule acts as a trust capsule, storing immutable evidence of actions, decisions, agreements, and reputations. It combines on-chain data (cryptographic records) and off-chain data (context, intentions, and metadata), ensuring traceability, integrity, and interoperability.

The goal is to create an open standard for digital trust—applicable to DAOs, dApps, and governance systems, as well as organizations that wish to operate with verifiable transparency.

⚙️ Technical Architecture

The system is divided into three interdependent layers:

1. Registration Layer (On-chain)

• Generates hashes of evidence on EVM-compatible networks (Ethereum, Arbitrum, Base, Polygon).
• Uses ERC-721 standards for creating NFT capsules (Trust Capsules).
• Records the time, origin, and integrity of the interaction.

2. Context Layer (Off-chain)

• Stores metadata and contextual information via IPFS or Arweave.
• Describes the purpose, authorship, and nature of the action or agreement.
• Maintains selective privacy (sensitive data is not publicly exposed).

3. Reputation Layer

• Consolidates evidence and interactions into a dynamic Trust Score.
• Can issue Trust Badges (reputation NFTs) based on behavior and verifications.
• Integrates with governance protocols (Snapshot, Tally, Safe).

---

💡 The Problem It Solves

Even in decentralized systems, trust between parties still depends on subjective interpretation. Trust Capsule bridges this gap by introducing an objective and verifiable layer of trust, solving:

• Low traceability of intentions and authorship;
• Lack of consistent reputational metrics;
• Disconnection between context (off-chain) and registration (on-chain).

---

🧩 Use Cases

• Decentralized Governance: verifiable recording of votes, decisions, and quorums.
• Web3 Collaborations: evidence of deliverables, co-authorships, and contributions.
• ESG and Impact Projects: traceability of commitments and sustainable indicators.
• Reputation Systems: creation of trust NFTs and interaction history.
• Digital Literacy: verifiable certifications of participation and learning.

🧭 Ethical and Sustainable Pillars

Trust Capsule fully adheres to ESG, SDG, and NetZero principles, with a commitment to:

• Transparency and interoperability;
• Carbon neutrality in infrastructure (via Arweave/Polygon Green);
• Open and participatory governance;
• Code under a free, auditable, and replicable license.

🧠 Data Structure (simplified)

Each Trust Capsule contains:

{
  "id": "TC-0x...",
  "issuer": "0x123...",
  "recipient": "0xABC...",
  "contextURI": "ipfs://bafy...",
  "timestamp": 1731234567,
  "trustLevel": 0.89,
  "metadata": {
    "type": "agreement",
    "category": "governance",
    "description": "Verifiable record of a DAO deliberation."
  }
}

---

🔗 Integrations

• n8n → workflow automation (automatic capsule issuance)
• Snapshot / Tally → voting and governance registration
• Safe / Gnosis → anchoring of multi-signature transactions
• CalangoFlux Agents → interoperability with AI agents
• ENS / Lens / Ceramic → linking of decentralized identities
