[Proposal Summary] Problem Statement

What is the problem you want to solve?

Open public spaces lack safe, reliable power. Students/visitors can’t study or charge devices. PV exists but lacks per-site visibility and tamper-evident reporting to justify expansion.

[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

We turn public-space PV into a verifiable public good: each pod’s telemetry is signed at the edge and anchored on Cardano (Merkle-root + CID), enabling anyone to cryptographically verify energy produced and delivered. The entire stack (gateway firmware, attestation contract, verifier CLI, DApp, BOM/wiring/SOPs) is open-sourced so other faculties/institutions (globally) can copy it with confidence. We aim for the project to have practical infrastructure (for Indonesia's climate), not a demo, with neutrality and tamper-evidence built-in.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

Five working islandable PV+battery pods powering real users in open parks, each producing daily on-chain attestations. Reviewers can scan a QR, open the DApp, and verify any CSV/Parquet row against the on-chain root. We’ll show availability, kWh generated/served, and the effect of O&M actions (e.g., panel cleaning). The package includes a replication kit that lets other sites deploy identical pods with the same verifiable MRV pattern.

Describe realistic measures of success, ideally with on-chain metrics.

1. Availability ≥95% across 3 pods (attested daily).
2. ≥1,000 sessions during pilot (counted via outlet events/usage logs; attested)
3. 100% dataset rows verify vs on-chain roots (verifier CLI pass-rate).
4. ≥2 O&M actions with ≥3% yield change (before/after periods attested).
5. ≥1 external adopters request/clone the kit within 60 days of the kit being completed.

On-chain metrics:

1. Daily attestations (1 root/day/pod)
2. Total attestation TXs
3. Verification proofs executed (recorded by verifier endpoint).

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

We will deploy five islandable PV+battery “Power Pods” that act as independent power sources in open public spaces, eliminating unsafe ad-hoc cabling and enabling outdoor study/events. Each pod integrates PV, charge controller, LiFePO₄ storage, inverter, lockable AC outlets, USB-C PD, and task lighting inside a weatherproof, tamper-resistant enclosure.

MRV & Cardano Attestation/Proof

A small edge gateway reads inverter/BMS/sub-meter data via RS-485/Modbus, applies time-sync, signs payloads with a device key, batches readings (e.g., 1–5-minute intervals) into a Merkle tree, stores raw files off-chain (e.g., IPFS/S3), and submits the daily Merkle root + content CID to a minimal Cardano smart contract. A public DApp + verifier CLI lets anyone fetch data and verify inclusion proofs against the on-chain root—removing spreadsheet ambiguity and making sustainability reporting tamper-evident.

Pilot Focus (Faculty of Engineering UGM)

We target three FT UGM mini-parks to maximize visibility and operational control:

1. Collaboration Park (in front of Department of Electrical and Information Engineering)
2. Architecture Park (Civil Engineering cluster center)
3. **Central Park **(beside Smart Green Learning Center)

and two more at high-density public spaces:

1. UGM IT Directorate Open Co-Working Space
2. UGM Central Library Park

This concentrates stakeholder access, EHS oversight, and student engagement, while building a flagship showcase.

Open-Source Replication

We will publish a replication kit (vendor-agnostic BOM, wiring diagrams, enclosure drawings, commissioning checklists, safety SOPs, threat model, firmware, contracts, verifier) so other faculties and external institutions can deploy identical pods with the same verifiable MRV workflow.

Why This Solves the Problem

1. Provides safe, reliable, independent power in open parks.
2. Produces credible, auditable evidence of kWh generated and served, supporting expansion decisions and ESG/GreenMetric reporting.
3. Creates a maintained, open blueprint for rapid replication across campus and beyond.

Safety & Compliance

Islanded by default; any subpanel tie-in uses export-limit = 0, RCDs, SPDs, proper earthing/bonding, lockout/tagout, and EHS sign-off. Outdoor enclosures are IP65+ with anti-tamper mounts; camera coverage recommended.

Positioning (Pilot Rationale)

FT UGM is positioned as a national engineering leader; piloting here enables rigorous testing, documentation quality, and sustained student involvement. Data products align with GreenMetric-style categories (Energy/Climate), now made cryptographically verifiable.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

1. Reusable oracle/attestation pattern: A reference meter→gateway→Merkle-root→Cardano flow usable for energy, water, EV, lab telemetry.
2. Public-goods software/hardware: Apache-licensed code, CERN-OHL-S hardware docs, CC-BY docs; easy to fork and improve.
3. Adoption & visibility: Physical installations with scan-to-verify UX (QR at each pod) connect everyday users to Cardano’s utility.
4. Education pipeline: Coursework/capstones contribute issues/PRs; long-term maintainers emerge.
5. Replication: Other campuses/municipalities gain a turnkey blueprint; more attestations → more on-chain activity and tooling maturity.

[Your Project and Solution] Capabilities & Feasibility

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Team coverage

1. Blockchain Engineer & PM: contracts, indexer/API, DApp, verifier, delivery.
2. Electrical Engineer (focus on Robotics/Electronics): RS-485/Modbus, secure signing, gateway firmware, field wiring, commissioning.
3. Electrical Engineer (focus on Power Storage/Safety): PV/storage sizing, protection, SoC/dispatch, testing.

We included the chance for active electrical engineering students as assistants as a way for increasing manpower and giving back to the community.

Accountability Mechanisms

1. Milestone-gated disbursements; public repos, tags, and release notes.
2. Evidence pack per milestone (photos/SLDs, attestation TXs, dataset CIDs, verification logs).
3. Timesheets mapped to tasks; change-control and risk register.

Feasibility Validation

1. M1 deploys one live pod + first on-chain attestation; validates end-to-end pipeline.
2. M2 adds two to four pods + public DApp/CLI; proves scale to 3 sites and outdoor reliability.
3. M3 finishes remaining pods and publishes open dataset v1 + replication kit; verifies O&M effect (e.g., cleaning).

How does the cost of the project represent value for the Cardano ecosystem?

1. Public goods first: Funds produce working public infrastructure + a reusable oracle/attestation stack (code, hardware docs, verifier) under permissive licenses.
2. High leverage: Three pods validate the end-to-end pattern; replication scales impact without re-funding core R&D.
3. On-chain utility: Daily attestations and public verification flows make Cardano visible and useful to non-crypto users.
4. Transparency: Milestone-gated payouts; evidence packs (TXs, CIDs, logs); clear unit economics.
5. Longevity: Off-the-shelf parts; student pipeline for maintenance; low OPEX.
