:brain: Project Overview

Title: MetaPay – Circulating Basic Income Using Digital Currency
Main Submission: [HyperHack Submission] MetaPay – A Circular Basic Income Simulator on Web3

MetaPay proposes a fully electronic, self-replenishing universal basic income (UBI) system using digital currency.
The model distributes ₩500,000 monthly per person for 10 months and recollects 10% of wallet balances at the end of each cycle, creating a sustainable closed-loop financial system.

To enhance fairness, prevent Sybil attacks, and ensure that each person receives only one UBI wallet, MetaPay integrates Alith’s decentralized identity (DID) protocol.

:link: Alith Integration Highlights

MetaPay uses Alith ZK-ID technology to:

  • :white_check_mark: Verify wallet uniqueness: Every UBI wallet is tied to a verified digital identity.
  • :white_check_mark: Prevent abuse: Limits one MetaPay account per real individual by integrating DID logic.
  • :white_check_mark: Ensure fairness: Everyone receives the same UBI payment without duplicate claims.

This approach guarantees that MetaPay remains a people-centered UBI system by excluding fake or mass-generated addresses.

:hammer_and_wrench: Technical Architecture

Layer Technology
DID Verification Alith SDK (ZK-ID)
Wallet React + Web3 + MetaPay UI
Smart Contract Solidity (ERC20 variant)
Backend Node.js + Express
Chain Metis Sepolia Testnet

:pushpin: Integration Method:

  • Alith API is called at wallet sign-up.
  • ZK-proof is required to complete wallet registration.
  • Verified identity → Unique MetaPay wallet → Monthly UBI distribution.

:movie_camera: Demo & Repos

:globe_showing_europe_africa: Impact of Integration

  • No duplicate accounts → trustable UBI system
  • No need for manual ID review → scalable deployment
  • Transparent, privacy-preserving identity layer

Alith makes MetaPay more robust, scalable, and reliable for real-world adoption.

MetaPay is more than just a system for distributing money.
Its fundamental purpose is the restoration of time—and through it, freedom.
We believe that when people are no longer bound solely by the demands of survival, they gain the power to shape their own futures.

While countries like South Korea can implement MetaPay using national ID systems, the model is also adaptable to other contexts through ZK-ID (Zero-Knowledge Identity) authentication, ensuring fairness and privacy even without centralized identity infrastructures.

Through this hackathon, I look forward to working with technical experts to refine and prototype the system.
We are not simply sharing money—we are sharing the right to choose how to live.

:writing_hand: Closing

MetaPay isn’t just a UBI project.
It’s a system designed to give time and freedom back to people through a digitally controlled, fair income cycle.
Thanks to Alith, MetaPay achieves the transparency and trust that true universal income needs.

Alith’s ZK-ID clearly adds crucial trust and fairness to MetaPay.
My question is: How is user privacy preserved during ZK-ID verification? In other words, how does the system ensure uniqueness without knowing the individual’s actual identity?

:locked_with_key: ZK-ID & Global Applicability

ZK-ID enables proof of uniqueness and eligibility without revealing personal data.
However, in countries like South Korea with strong ID infrastructure, MetaPay can run securely without ZK-ID.

Korea can issue MetaPay wallets per person, auto-block duplicates and manage lifecycle securely.
Other nations can use eIDAS, Aadhaar, social numbers, or DID on-chain proofs.

:counterclockwise_arrows_button: Circulation Model Overview

  • Distribute ₩25 trillion monthly from Month 1–10
  • Start recollection of 10% balance at end of Month 10
  • Reissue the recollected ₩25 trillion on Month 11, 00:00

This creates a sustainable closed loop, without new taxes.

:money_with_wings: Transaction Structure

Every purchase =
→ 50% MetaPay
→ 50% regular money (cash, card, etc.)

:white_check_mark: Prevents MetaPay hoarding
:white_check_mark: Keeps usage visible without revealing identities
:white_check_mark: Ensures fairness, fluidity, and traceability

:seedling: Why MetaPay?

MetaPay isn’t just a UBI project.
It gives people time and freedom to live with dignity and purpose.

With basic security provided by MetaPay, people can:

  • Reflect and participate in democracy
  • Care for family or pursue education
  • Focus on creativity, community, and climate solutions

We believe that time is the true currency of freedom.

Reply to han (Marketing Guild Insider):

Thank you for your thoughtful question.

ZK-ID (Zero-Knowledge Identity) ensures both uniqueness and privacy through cryptographic proofs that verify identity attributes without revealing the underlying personal information.

Here’s how MetaPay leverages it:

  • :locked_with_key: Uniqueness is achieved by assigning each participant a cryptographic identifier derived from secure credentials (e.g., passport, government-issued ID, or biometric hash). The proof ensures one-person-one-wallet, but the original ID data is never shared or stored.
  • :shield: Privacy is maintained because the system only verifies the “truth” of the statement (e.g., “this person hasn’t claimed basic income elsewhere”) without knowing who the person is.
  • :globe_with_meridians: Fair access across jurisdictions is supported, since even in countries lacking a central ID system, ZK-ID frameworks like Alith’s enable decentralized identity verification.

This allows MetaPay to maintain fairness, prevent double claims, and build trust—all while preserving anonymity.

Let me know if you’d like a technical breakdown or would be interested in trying the simulation interface when it’s ready!

:puzzle_piece: Additional Perspective – For Bonus Track Review

While my earlier post focused on the technical mechanism behind MetaPay’s distribution and recollection cycle, I’d like to share a few broader aspects that highlight the system’s adaptability, policy relevance, and long-term potential.

:globe_showing_europe_africa: ZK-ID Stack Agnosticism
Although the prototype currently uses Alith ZK-ID, MetaPay’s architecture is fully compatible with other ZK identity systems like Polygon ID, Semaphore, or Worldcoin’s ZK stack. This ensures it can be adopted across diverse regulatory or social environments without requiring architectural changes.

:identification_card: On-Chain DID Compatibility
We are preparing to integrate decentralized identifiers (DIDs) in future iterations, enabling persistent identity verification and reusability. This enhances Sybil resistance and allows each verified user to maintain a secure, on-chain identity anchor—without compromising privacy.

:classical_building: Policy Alignment & Government Use Case
MetaPay has been submitted to national policy platforms in South Korea as a practical, tax-free basic income pilot. Since it operates in parallel with existing welfare systems, it remains politically feasible and socially non-disruptive—making it an attractive option for government-led trials.

:test_tube: Low-Risk Simulation for Public Engagement
The testnet-based simulator allows anyone to experience the full-cycle UBI logic (distribute → reclaim → redistribute) with zero real-world financial risk. This encourages civic participation and enables policymakers to evaluate the system before real-world deployment.

:brick: Open Source & Interoperability
All smart contracts are modular, auditable, and open-source—designed to be forked, customized, or integrated into other UBI implementations. MetaPay is more than a demo; it’s a policy-grade architecture that invites global collaboration and innovation.

:bullseye: MetaPay is not just a Web3 application—it’s a bridge between technical innovation and social equity. Thank you for the opportunity to present it through this Bonus Track.

Hi @Xomi, welcome to the community! :waving_hand:
Thank you for your first post — I’m honored that it’s on the MetaPay thread :folded_hands:

Let me explain what Alith does for this project — it’s actually a core pillar of how MetaPay works.

:locked_with_key: 1. ZK-ID: Privacy-Preserving Identity Verification

Alith provides Zero-Knowledge Identity (ZK-ID) technology to ensure that:

  • Each person receives only one MetaPay wallet
  • Without revealing personal identity (e.g., name, ID number, etc.)

This helps us prevent Sybil attacks and duplicate claims while keeping all users fully anonymous.

In countries with national ID systems (like Korea), wallets can be issued automatically at birth and deactivated at death.
In other countries, Alith ZK-ID provides a decentralized way to prove uniqueness without centralized ID databases.

:white_check_mark: Fair. :white_check_mark: Private. :white_check_mark: Scalable.

:robot: 2. Alith AI: Intelligent Monitoring & Governance

MetaPay also integrates Alith AI, which acts as a real-time financial and governance assistant:

A. Monitors:

  • Total payouts and recollections
  • Wallet activity across the network
  • Demographic trends (e.g., births/deaths)
  • Surplus or deficit in each payment cycle

B. Predicts:

  • The impact of adjusting payout or collection rates
  • Provides data-driven recommendations to the DAO before any proposal is voted on

C. Detects Abuse:

  • Identifies unusual transaction patterns (e.g., wage manipulation or bypassed recollection)
  • Alerts the DAO or National Tax Service for audits

:right_arrow: This helps ensure that MetaPay stays fair, usable, and protected from misuse.

:credit_card: 3. Enforces Hybrid Payment Rule: 50% MetaPay + 50% Fiat

With every purchase, wallets auto-split payments:

  • Half from MetaPay
  • Half from user’s linked fiat (cash, card, etc.)

If this balance becomes inefficient, Alith AI suggests a new ratio (like 60:40), and the DAO can vote on adjustments.

:brain: Summary

Alith = The brain and immune system of MetaPay.
It secures identity, protects fairness, guides economic policy, and adapts in real time.

Thanks again for your thoughtful question, and once again — welcome aboard! :tada:
If you’d like a technical breakdown or want to try the simulation, I’d be happy to share.

:coin: MetaPayP2P — Circulating Basic Income Simulator with AI & Web3
Powered by Smart Contracts, Alith AI, and OpenAI API

metapay_ai_result
metapay_ai_result1920×1080 197 KB

:light_bulb: What Problem Does It Solve?

Most basic income systems suffer from the same issue — they are static, tax-reliant, and unsustainable over time.
MetaPayP2P proposes a fundamentally new economic model: a circulating basic income system governed by smart contracts and monitored by AI.

Rather than relying on theory, spreadsheets, or whitepapers, this project offers a fully interactive and working simulation on-chain. It visualizes how digital basic income can be distributed, spent, recollected, and analyzed within a closed economy — autonomously and sustainably.

:link: Why Web3?

MetaPayP2P leverages the core strength of Web3: programmable money with transparent rules. This is not just a crypto wallet — it’s a live economic system with its own rules, contracts, and citizens.

  • :receipt: Smart contracts distribute income equally to 10 citizen wallets.
  • :repeat_button: After every 10 distribution cycles, 10% of each citizen’s unspent MetaPay is automatically recollected.
  • :handshake: Citizens and companies can freely transfer value between one another, simulating real-life consumption, business activity, and wealth flow.
  • :hammer_and_wrench: No new funding is needed after initial pool — the system is self-circulating and mathematically sustainable.

:white_check_mark: Built With:

  • Solidity for Smart Contract Logic
  • React + Vite for Frontend
  • Node.js Express Server for AI integration
  • OpenAI API for dynamic economic logic
  • Alith AI SDK for blockchain-aware alerts
  • Deployed on Vercel (Frontend) + Render (AI backend)

:brain: Why AI? — Real-Time Economic Oversight

MetaPayP2P is not a passive simulation — it actively monitors the ecosystem using AI.

It integrates both OpenAI API and Alith AI to provide intelligent alerts about user behavior and systemic risks:

  • :warning: Detects potential monopolies, e.g., when a company receives >50% of total user transactions
  • :warning: Flags citizen wallets that hoard income or avoid circulating funds
  • :warning: Identifies transaction anomalies such as one-time spikes or circular loops between a few actors

:magnifying_glass_tilted_left: Example Insights (from live demo):

:pushpin: “Company1 is the most frequent recipient of transactions from 4 different users.”
→ This indicates market dominance and possible centralization.

:pushpin: “User4 is the only wallet transacting with Company2.”
→ Suggests a unique or exclusive business relationship.

These insights are not hidden in logs — they are rendered directly in the user interface, helping testers and policymakers make real-time judgments.

:brain: Future upgrades may allow AI-governed treasury logic, where AI can dynamically adjust distribution ratios or recollection rates based on behavioral analysis. This moves the project closer to DAO-ready policy automation.

:coin: How the Circulation Works

To visualize the core model:

plaintext

복사편집

National Wallet → [Distribute 10x] → Citizens  
Citizens Spend → Companies  
After 10 cycles → [Recollect 10% of unspent funds] from each citizen  
→ Repeat (sustainable loop)

There is no destruction or inflation — funds flow in a loop.
Only 50,000 units are used to simulate infinite cycles of basic income for 10 users.

:rocket: Why This Project Fits the Bonus Track

MetaPayP2P isn’t just another DApp — it’s a working economic prototype with strong Web3 and AI integration.

:white_check_mark: Fully on-chain basic income simulation
:white_check_mark: Working P2P and B2B transfers (User ↔ User, User ↔ Company, Company ↔ Company)
:white_check_mark: Smart contract-based recollection logic enforces sustainability
:white_check_mark: AI (OpenAI + Alith AI) provides live policy monitoring

  • :brain: See how AI flags patterns like monopoly or hoarding

All of this is visible, explorable, and repeatable — making it suitable for demos, education, policy testing, or DAO simulation.

:crystal_ball: Vision

MetaPayP2P is more than a demo. It is:

  • A blueprint for how digital economies could operate with fairness and automation
  • A platform for experimental governance and AI-driven public policy
  • A modular model that any digital nation, DAO, or community could adopt

We hope this prototype inspires a new wave of projects that take basic income from theory to simulation, and eventually, to policy.
