A field worker in rural Tanzania sends a WhatsApp video. A donor in Melbourne funds a surgery. A surgeon gets paid the moment a child is verified home. No forms. No invoices. No bank accounts required. No understanding of technology needed by anyone on the ground.
Nobody in this system needs to understand how it works. Let sends a video. Eli sends a video. The nurse sends a video. A piece of software called a webhook receives every message and automatically handles everything else — the record keeping, the fraud checks, the YouTube upload, the blockchain entry, and the payment.
The technology is invisible. The outcome is real.
Every donor receives a digital receipt that updates in real time. It starts as an incomplete picture — one piece minted at each stage of the journey. When all seven stages are verified and the picture is complete, the smart contract releases payment to every actor simultaneously.
The complete NFT is the donor's permanent proof. Not a PDF. Not a report. A verifiable, on-chain record that their money reached a real person and produced a real outcome.
When the seventh piece drops, the picture completes. The smart contract releases payment to everyone simultaneously. The donor's NFT is now a permanent, verifiable receipt — on-chain, forever.
When Let submits a proof video, he receives POC Coins showing his share of the budget — say $90 worth. He can see his money coming. But he cannot spend it, transfer it, or cash it out.
POC Coins are locked until the final verification is complete. If the chain breaks — if the child cannot be located, if proof fails, if the deadline passes — the coins are forfeited and the donor's USDC returns automatically.
When the outcome is verified, the coins burn and USDC is sent to every actor simultaneously. For Let in Tanzania, that arrives as an M-Pesa notification within minutes.
The contracts run on Base — a public blockchain owned by nobody, auditable by everyone. Once deployed, even POC cannot change the rules. The funder's money is safe because the contract enforces it, not because POC promises to.
A fraudulent submission earns nothing unless every subsequent stage in the chain is also fraudulent — a sustained, coordinated effort that costs more than it returns. The system makes honest behaviour structurally more valuable than dishonest behaviour.
The same system that tracked the first surgery tracks the thousandth. The proof chain is the system. Adding more cases does not require more staff, more offices, or more reporting layers. It requires more actors — who are registered, rated, and paid automatically.
The same system applies to flood relief, girls' education, veterans' mental health, and social housing. Different outcomes. Different actors. Different countries. Same proof chain. Same technology. Same result.
No forms. No invoices. No bank accounts. No understanding of technology. A field worker with a basic Android phone is the starting point of a chain that is auditable by any government, visible to any donor, and permanent on a public blockchain forever.
