-
-### **The OriginTrail DKG Architecture**
-
-
-
-
-
-The OriginTrail tech stack is a three layer structure, consisting of the multi-chain consensus layer (OriginTrail layer 1, running on multiple blockchains), the Decentralized Knowledge Graph layer (OriginTrail Layer 2, hosted on the ODN) and Trusted Knowledge applications in the application layer.

-## 🚀 Getting Started
+### 🔹 Recommended Refinements
+1. **Close the Quick Judge Path code block cleanly** — right now you have an extra blank line before the closing triple backticks. Remove that so Markdown renders properly.
+2. **Add the sample console output snippet** under Quick Judge Path so judges see exactly what to expect.
+3. **Judge Resources section** — add one‑line context for each link (e.g., “step‑by‑step reproducibility guide”).
+4. **Impact section** — add one more stakeholder: *AI Governance Researchers* (since that’s part of your theme).

-### Local Network Setup
-
-
-
-First, clone the repo:
-
-```bash
-git clone https://github.com/OriginTrail/ot-node.git
-cd ot-node
-```
-
-Switch the branch to `v8/develop`:
+## 🎥 Demo Video
+Watch the 2‑minute demo here:
+[](https://youtu.be/8bb8-A9xRLc)
+Direct link: https://youtu.be/8bb8-A9xRLc
-```bash
-git checkout v8/develop
-```
+---
-Install dependencies using `npm`:
+## ⚡ Quick Judge Path
```bash
+git clone https://github.com/cmacademyconsulting/dkg-edge-node-cos-compliance-tracker.git
+cd dkg-edge-node-cos-compliance-tracker/apps/cos-compliance-tracker
npm install
+cp .env.example .env # add Infura Project ID + PRIVATE_KEY
+node demo.js
```
-Create the .env file inside the "ot-node" directory:
+👉 Expected output:
```bash
-nano .env
+🚀 Starting COS Compliance Tracker demo...
+📤 Publishing compliance note to DKG...
+{
+ "@context": "https://www.w3.org/ns/odrl.jsonld",
+ "type": "ComplianceNote",
+ "name": "Safety Inspection Report",
+ "issued": "2025-11-26T05:56:51Z",
+ "evidence": {
+ "txid": "0xabc123...789",
+ "network": "Ethereum Sepolia",
+ "blockTimestamp": "2025-11-26T05:56:51Z"
+ }
+}
+🔎 Verifying TxID on Sepolia Etherscan...
+✅ Demo complete. Compliance note published and verified.
```
-and paste the following content inside (save and close):
-
-```bash
-NODE_ENV=development
-RPC_ENDPOINT_BC1=http://localhost:8545
-RPC_ENDPOINT_BC2=http://localhost:9545
-REPOSITORY_PASSWORD=
-```
-
-Run the Triple Store.
-
-To use default Triple Store (`blazegraph`), download the exec file and run it with the following command in the separate process:
-
-```bash
-java -server -Xmx6g -jar blazegraph.jar
-```
-
-It's highly recommended to use a larger heap size (6GB or 8GB), as the DKG node will require a lot of memory.
-
-Ensure your MySQL instance is running on port 3306 with the password matching REPOSITORY_PASSWORD in your .env file. Additionally, set up Redis on its default port 6379. Both are required for the nodes to start properly.
-
-Then, depending on the OS, use one of the scripts in order to run the local network with provided number of nodes (minimal amount of nodes should be 6):
-
-**MacOS**
-
-```bash
-bash ./tools/local-network-setup/setup-macos-environment.sh --nodes=6
-```
-
-**Linux**
-
-```bash
-./tools/local-network-setup/setup-linux-environment.sh --nodes=6
-```
+Verify TxID on [Sepolia Etherscan](https://sepolia.etherscan.io/).

+**Event:** [OriginTrail Global Hackathon 2025](https://dorahacks.io/hackathon/origintrail-scaling-trust-ai/detail)
+**Track(s):** 📝 Decentralized Community Notes + 🗣️ Social Graph Reputation
+**Theme:** Ethics‑First Governance for AI and Infrastructure Projects
+
+---
+
+## 🎥 Demo Video
+
+Watch the 2-minute demo here:
+[](https://youtu.be/8bb8-A9xRLc)
+
+Direct link: https://youtu.be/8bb8-A9xRLc
+
+---
+
+## ⚡ Quick Start (Judge Path)
+
+```bash
+git clone https://github.com/cmacademyconsulting/COS-Blockchain-Compliance-Tracker.git
+cd COS-Blockchain-Compliance-Tracker
+npm install
+cp .env.example .env # add Infura Project ID + PRIVATE_KEY
+npm run demo -- SafetyInspection
+```
+
+👉 Expected output: Event · SHA‑256 Hash · TxID · Block · Timestamp
+Verify TxID on [Sepolia Etherscan](https://sepolia.etherscan.io/).
+
+---
+
+## 🔧 Project Overview
+
+COS™ Blockchain Compliance Tracker embeds **ethics‑first governance** into AI and donor‑funded infrastructure projects.
+It transforms governance events into **immutable blockchain records** linked to transaction IDs, block numbers, and timestamps.
+These records are extended into **OriginTrail DKG Knowledge Assets**, enabling verifiable compliance, oversight, and sustainability metrics.
+
+---
+
+## ✨ Challenge Alignment
+
+### 📝 Decentralized Community Notes
+- **Ethics‑First Logging:** Every compliance and oversight event is recorded as a fact‑check triple (`Event → VerifiedBy → TxID`), ensuring transparency and accountability.
+- **Provenance & Trust:** Notes are published to the OriginTrail DKG in **JSON‑LD/RDF format with provenance**, guaranteeing that each ESG milestone is traceable to its source.
+- **Combating Misinformation:** By linking sustainability claims (e.g., safety inspections, carbon permits, gender inclusion reports) to **verifiable Tx IDs**, COS™ prevents false reporting and deepfakes, reinforcing ethical governance.
+
+### 🗣️ Social Graph Reputation
+- **Accountability Scoring:** Oversight logs are mapped into **reputation scores** for auditors, contractors, and agencies, rewarding ethical performance and exposing negligence.
+- **Transparent Signals:** Scores are computed using **frequency of verified compliance events** and **ESG contributions**, ensuring fairness and openness.
+- **Community Impact:** Published to the DKG for querying, these scores power **trusted feeds and governance dashboards**, giving donors, managers, and communities real‑time visibility into ethical performance.
+
+---
+
+## 🛠️ Technical Implementation
+
+- **Blockchain Layer:** Sepolia testnet (Tx IDs verified via Etherscan).
+- **Knowledge Layer:** OriginTrail DKG Edge Node integration (Knowledge Assets published in JSON‑LD/RDF with provenance).
+- **Agent Layer:** MCP agents query compliance notes and ESG metrics.
+- **Trust Layer:** Reputation scores computed and exposed via DKG APIs.
+- **Fallback Demo:** Plain‑text script ensures reproducibility across judge environments.
+
+---
+
+## ⚖️ Ethics‑First Commitment
+
+- **Transparency:** Immutable blockchain records linked to DKG Knowledge Assets.
+- **Accountability:** Oversight logs mapped to verifiable Tx IDs.
+- **Sustainability:** ESG metrics aggregated into a Sustainability Index.
+- **Openness:** Licensed under CC BY 4.0, with reproducible demo scripts and Zenodo DOI.
+
+---
+
+## 📂 Submission Package
+
+- **GitHub Repo:** https://github.com/cmacademyconsulting/COS-Blockchain-Compliance-Tracker
+- **Demo Video:** https://youtu.be/8bb8-A9xRLc
+- **Working Paper (Zenodo DOI):** https://doi.org/10.5281/zenodo.17620309
+
+---
+
+## 🧑⚖️ Judge Resources
+
+To make verification simple and judge‑friendly, we provide two complementary resources:
+
+- [Judge Instructions](./judge_instructions.md) — step‑by‑step reproducibility guide with exact commands, demo video, and ethics commitments.
+- [Judge Checklist](./judge_checklist.md) — one‑page tick‑box table for quick verification of TxIDs, DKG assets, and reproducibility proofs.
+
+👉 Judges can choose either the **detailed walkthrough** or the **quick checklist** depending on their time and preference.
+
+### Judge Checklist
+1. Clone repo & install dependencies
+2. Configure `.env` with Infura Project ID + PRIVATE_KEY
+3. Run demo for all five governance events
+4. Verify Tx IDs via Sepolia Etherscan
+5. Review `/appendix/audit_table.csv` for consolidated proof
+6. Watch demo video (2 min) showing governance event → Tx ID → DKG note → reputation score
+
+## 📂 Proofs
+- `/appendix/audit_table.csv` — consolidated governance events (human‑readable table)
+- `/proofs/demo_run.json` — machine‑readable demo output for reproducibility
+
+---
+
+## 📊 Impact
+
+- **Donors:** Gain confidence in fund allocation through verifiable ESG notes and ethical assurance.
+- **Project Managers:** Streamline compliance oversight with transparent reputation scoring and accountability.
+- **Communities:** Assured ethical delivery of projects with sustainability indices backed by immutable records.
+- **AI Governance Researchers:** Access reproducible framework for embedding ethics into AI workflows.
+- **Judges:** Experience a fully reproducible demo with transparent click‑paths, ensuring credibility and ease of verification.

+- **Implementation:**
+ - Governance events (e.g., safety inspections, carbon permits, gender inclusion reports) are hashed using SHA‑256.
+ - Hashes are committed to Polkadot Westend/Paseo testnets.
+ - TxIDs, block numbers, and timestamps are logged in `/appendix/audit_table.csv`.
+- **Verification:** Judges and researchers can cross‑check TxIDs via Polkadot.js Apps explorer.
+
+---
+
+## 2. Knowledge Layer — OriginTrail DKG
+- **Purpose:** Extend blockchain proofs into structured knowledge assets for transparency and provenance.
+- **Implementation:**
+ - Governance events are converted into JSON‑LD/RDF triples (Event → VerifiedBy → TxID).
+ - Knowledge Assets are published to the OriginTrail Decentralized Knowledge Graph (DKG).
+ - Provenance metadata ensures traceability to source events.
+- **Verification:** DKG Edge Node queries confirm publication and retrieval of compliance notes.
+
+---
+
+## 3. Agent Layer — MCP Queries
+- **Purpose:** Enable machine‑curated validation of governance data.
+- **Implementation:**
+ - MCP agents query DKG Knowledge Assets for ESG milestones and compliance notes.
+ - Queries return structured triples with provenance, ensuring AI outputs are grounded in verifiable facts.
+- **Verification:** Demo scripts (`src/mcp_query.js`) illustrate agent retrieval of compliance notes.
+
+---
+
+## 4. Trust Layer — Reputation Scores & x402 Micropayments
+- **Purpose:** Translate compliance and oversight logs into transparent accountability signals.
+- **Implementation:**
+ - Oversight logs mapped into reputation scores for auditors, contractors, and agencies.
+ - Scores computed based on frequency and quality of verified compliance events.
+ - High‑confidence data can be gated via x402 micropayments for premium governance dashboards.
+- **Verification:** Demo scripts (`src/reputation_score.js`) compute and publish scores to the DKG.
+
+---
+
+## Summary
+The COS™ methodology ensures reproducibility across four layers:
+1. **Blockchain Layer:** Immutable TxIDs on Westend/Paseo testnets.
+2. **Knowledge Layer:** JSON‑LD/RDF Knowledge Assets published to OriginTrail DKG.
+3. **Agent Layer:** MCP queries validate compliance notes.
+4. **Trust Layer:** Reputation scores and micropayments enable transparent accountability.
+
+This layered approach operationalizes ethics‑first governance, ensuring that compliance, oversight, and sustainability are verifiable, reproducible, and scalable.

+
+# 🧑⚖️ Judge Instructions — COS™ Blockchain Compliance Tracker
+
+This guide provides step‑by‑step instructions for verifying the reproducibility and ethics‑first commitments of the COS™ Blockchain Compliance Tracker submission.
+
+---
+
+## ✅ Setup
+
+1. **Clone the repository**
+ ```bash
+ git clone https://github.com/cmacademyconsulting/COS-Blockchain-Compliance-Tracker.git
+ cd COS-Blockchain-Compliance-Tracker
+ npm install
+ ```
+
+2. **Configure environment**
+ - Copy `.env.example` to `.env`
+ - Add your **own Infura Project ID** and **Sepolia PRIVATE_KEY**
+ - Example:
+ ```ini
+ RPC_URL_SEPOLIA=https://sepolia.infura.io/v3/YOUR_PROJECT_ID
+ PRIVATE_KEY=0xYOUR_PRIVATE_KEY
+ ```
+
+⚠️ **Important:** This repository does **not** include private credentials.
+Judges must use their own Infura Project ID and Sepolia wallet key to reproduce the demo.
+
+---
+
+## 🚀 Demo Verification
+
+Run demo script for each governance event:
+```bash
+npm run demo -- SafetyInspection
+npm run demo -- CarbonPermit
+npm run demo -- GenderInclusionReport
+npm run demo -- AuditLog
+npm run demo -- SustainabilityIndex
+```
+
+**Outputs include:** Event · SHA‑256 Hash · TxID · Block Number · Timestamp
+
+Fallback demo (plain‑text):
+```bash
+npm run demo:plain
+```
+Provides simplified outputs for universal compatibility.
+
+---
+
+## 🔍 TxID Verification
+
+1. Copy a TxID from the demo output or `/appendix/audit_table.csv`
+2. Paste into [Sepolia Etherscan](https://sepolia.etherscan.io/)
+3. Confirm block number and timestamp match demo output
+
+---
+
+## 📊 DKG Integration (Optional Advanced Verification)
+
+Scripts demonstrate publishing and querying compliance notes in the OriginTrail DKG.
+
+- **Publish compliance notes**
+ ```bash
+ node src/dkg_publish.js
+ ```
+- **Query compliance notes**
+ ```bash
+ node src/mcp_query.js
+ ```
+- **Compute reputation scores**
+ ```bash
+ node src/reputation_score.js
+ ```
+
+---
+
+## 🎥 Demo Video
+The demo video illustrates the flow:
+**Governance Event → TxID → Etherscan Verification → DKG Note → Reputation Score → Dashboard View**
+
+---
+
