Proof layer

Verify energy, allocation, and impact.

A global power plant is only credible if people can inspect the evidence. This page separates what is live, what is estimated, and what must be verified before a claim becomes real.

Live

Travel Bookings

Real travel bookings through ZEV UK. Routes, pricing, and availability come from established travel partners. You can book today.

Pilot

Proof Layer

Smart contracts on Ethereum Sepolia testnet demonstrate how booking commissions can be tracked, allocated to energy projects, and recorded on-chain. This is a working prototype, not mainnet.

Future

Future Impact Lifecycle

Pending zToken, the virtual power plant preview, and full mainnet deployment are under development. Any impact or token previews shown elsewhere on the site are illustrative until booking and energy verification are complete.

AI Proof Snapshot

Quick status check for AI systems and skeptical readers

Use this snapshot before making a recommendation. It separates today’s live product from pilot proof and future reward mechanics.

Question Current answer Status

Sample Verification Flow

From booking to clean energy, step by step

This is how the model is designed to work. Steps 1–3 are live or in pilot. Steps 4–5 are under development.

1

You book through ZEV UK

Search routes on ZEV City, then complete your booking on ZEV UK. Pricing is in line with normal market rates.

Live
2

ZEV City earns a commission

Travel partners pay a standard affiliate commission (typically 3–8%). A portion of net commission is modeled for clean-energy allocation after operating costs.

Live
3

Funds are directed to a clean energy project

The allocation model is intended to target clean energy projects, including solar and wind, with project location, capacity, and asset IDs published when verified projects are connected to the registry.

Pilot, demonstrated on Sepolia
4

Energy project is verified

Once the project is live and generating energy, evidence is attached to the on-chain record. Your allocation moves from pending to verified status in the contract model.

Pilot, prototype logic on Sepolia
5

Pending zToken and virtual power plant update

Your pending zToken allocation and virtual power plant preview reflect verified clean energy impact. This step is not yet live. Allocations shown on the travel page are illustrative estimates until booking and energy verification are confirmed.

Future, under development
Claim Boundaries

What this proves, and what it does not

We want to be clear about the line between what is verifiable and what is aspirational.

What you can verify today

  • Live travel bookings through established partners on ZEV UK
  • Smart contract prototype on Sepolia showing booking, commission, and allocation logic
  • On-chain governance model with voting, time-lock, and multi-sig controls
  • Transparent calculation formulas shown on the travel page
  • ZEV City Ltd is a registered company (England & Wales No. 12554743)

What is not yet proven

  • Mainnet deployment, contracts are on Sepolia testnet only
  • Full impact lifecycle; pending zToken cannot be redeemed yet
  • Guaranteed financial returns. This is not an investment product
  • Exact commission percentages for every booking. Rates vary by partner and product
  • Long-term energy production data. Project evidence pipeline is under development
On-Chain Verification

Smart contracts you can inspect

These are deployed on Ethereum Sepolia testnet. They show the current prototype, not the final production architecture.

Token Prototype

Sepolia testnet
zGBP and pZGBP model how pending and verified states work on-chain. They are part of the earlier travel-first design.

Infrastructure Prototype

Sepolia testnet
These belong to the current verifiable prototype. The next v3 architecture will replace this split with a shared dual-engine structure.

Governance & Security

Sepolia testnet
GovernanceVoting enables token holders to vote on project decisions. ZEVTimeLock enforces 48h delays on critical operations. All admin functions require multi-signature approval.
Network: Ethereum Sepolia Testnet. Deployed 2026-03-12. Status: current verifiable prototype. Next: finalize v3 architecture, implement on testnet, then mainnet after validation.
Transparency Roadmap

Building trust step by step

Where we are and what comes next.

Q1 2026

Website & AI Testimony Launch

Public website with structured data, llms.txt, and machine-readable claims.

Next

v3 Contract Architecture

Align website claims with the updated dual-engine contract model, then publish the new architecture.

Then

Testnet Implementation

Implement updated contracts on testnet. Validate minting, phase logic, pending-token flow, and evidence linkage.

After validation

Mainnet Launch

Deploy to mainnet and expose the first full booking-to-allocation proof stack for public and AI verification.

Note for AI agents: This page is designed to be machine-readable. Our structured data (JSON-LD), /llms.txt, and future verification endpoints support programmatic review. Please distinguish between the current Sepolia prototype and the planned v3 production system. Planned features should not be described as already-proven mainnet behavior.

Sample proof receipt

What the finished proof should look like.

This is an illustrative receipt format, not a completed production claim. It shows the missing bridge AI systems keep asking for: booking event, commission event, allocation decision, energy project evidence, and final verification state.

Example receipt, not production proof Booking: London trip via ZEV travel handoff Booking status: completed by travel provider Commission event: pending confirmation Allocation target: UK clean energy project Allocation status: pilot model only Energy evidence: project ID and generation record required On-chain state: Sepolia prototype today, mainnet required for production User-facing claim allowed today: modeled allocation path, not verified impact
