O Coin’s Climate Fix Pitches a Water-Pegged Stablecoin to Pay for Cleanup

Christophe Normand, a developer who says he forked Bitcoin Core to build a currency for climate work, wants the next unit of cleanup money to be pegged to a liter of bottled water. His project, O Coin, sets 1 O = 1 liter of water at the local price for each fiat currency lane it covers, and proposes to mint new O only when verified environmental work is delivered. The pitch is that a water-anchored, programmable currency can pay for carbon removal, ocean plastic, and reforestation without issuing debt or waiting on grants.

The cleanup machines exist. The Ocean Cleanup has pulled more than ten million kilograms of plastic from the Pacific and from rivers since 2019. Climeworks has raised over a billion dollars and operates direct air capture plants in Iceland. The gap is the payment layer: carbon credits are cheap and volatile, philanthropic capital is capped, and venture capital wants ten-times returns that cleanup work doesn’t deliver. O Coin is designed to sit in that gap. As of mid-2025 it remains open-source code and published essays, with a pre-booking announcement in late summer 2025 and no documented mainnet for the water-pegged currency.

What O Coin Actually Is

Normand laid out the design in a long essay republished through MEXC News, describing a family of stablecoins, one per national fiat, calibrated to the average local price of a liter of bottled water. The choice of water, he wrote, is because it is universally needed, locally priced, and not controlled by any single entity. Value, in the model, comes from the measurement, not from a scarce supply cap.

O International is registered as a French Non-Profit Association, and Normand publishes his work through HackerNoon under the handle @chris127, including essays on Universal Basic Income and restoration finance built on the same water-pegged unit. The codebase is described in the pitch as a fork of Bitcoin Core, with new coins created by protocol rules rather than borrowed from future taxpayers. In late summer 2025 an Instagram account associated with the project announced that pre-booking would start on September 6 or 7.

1 O Coin = 1 liter of bottled water average price in your local currency… I chose water because everyone needs it, demand is stable, and no single entity controls global prices.

the founder’s published case for water-pegged money lays out the full pitch in his own words, including the claim that stablecoins have always been sold as stable because their issuers said so, while O Coin would peg to a measurable physical unit instead.

The Cleanup Work That Already Exists

Direct air capture plants, ocean cleanup fleets, and drone-planting crews all operate today with verifiable, sourced output. The money for them, not the engineering, is the bottleneck. That is the precise hole O Coin claims it was built for.

Climeworks was the first company to start up a commercial direct air capture plant. It raised $162 million from private investors in 2025, taking total funding past $1 billion. The Iceland plant Mammoth captured only 105 metric tons of CO2 in its first 12 months of operation against an annual capacity of 36,000 tons. As of June 2025, only 12 of Mammoth’s 72 planned collector containers were fully operational, according to IDTechEx senior technology analyst Eve Pope.

The Ocean Cleanup announced on Earth Day 2024 that it had removed a verified all-time total of ten million kilograms of trash from oceans and rivers, the weight of the Eiffel Tower. The non-profit was founded in 2013 by Boyan Slat, who remains its Founder and CEO, and the organization now employs roughly 140 staff headquartered in Rotterdam. Plastic is tracked through DNV’s chain-of-custody model to certify claims of origin when recycled into new products. Cleaning operations run in the Great Pacific Garbage Patch and in rivers across eight countries.

The hardware works. The cash flow doesn’t. That is the gap the pitch sits in.

• $162 million – Climeworks 2025 funding round
• $1 billion+ – Climeworks total funding to date
• 10,000,000 kg – Ocean Cleanup verified catch as of Earth Day 2024
• 105 t – Mammoth plant CO2 capture in its first 12 months

See the $162 million raise and Mammoth plant delays for the funding context, and verified catch totals from the Great Pacific Garbage Patch for the Ocean Cleanup milestone.

Why the Funding Model Is Stuck

The voluntary carbon market is the incumbent payment layer for climate work, and it is not paying enough. The World Bank’s 2026 State and Trends of Carbon Pricing report finds that carbon pricing now covers nearly 30% of global greenhouse gas emissions across 87 implemented policies, and that carbon pricing mobilized over $107 billion for public budgets in 2025. In carbon crediting markets, overall credit issuances rose 8% from 2024 to 2025, while credit prices declined slightly across 2025, with certain project types, including those eligible for use by international airlines and highly rated forest conservation and reforestation projects, continuing to earn a price premium.

Quality is fragmented and demand is thin. Sylvera reported that the average spot price for high-quality ARR credits rose to $26 per tCO2e in December 2025, up from $14 at the start of the year, evidence of a flight to quality rather than a broad market recovery. CDR.fyi’s 2025 Direct Air Capture Market Snapshot tallies 0.05% delivered of contracted DAC credits as of mid-2025, with just three companies, 1PointFive, Climeworks, and Heirloom, accounting for 80% of total DAC credits sold and Microsoft leading buyers at 833,000 tonnes purchased.

The funding gap is not invented. It is measured. The IEA’s Net Zero Roadmap states that annual clean energy investment worldwide needs to more than triple by 2030 to around $4 trillion. The Climate Policy Initiative’s 2025 Global Landscape of Climate Finance cites an average need of $9.2 trillion per year from 2031 to 2050 to stay on a 1.5°C-aligned pathway.

How the Smart Contract Layer Would Work

Normand’s published design sets out a five-step flow. A goal is defined in physical units. O Coins are minted into a smart contract as escrow for outcomes, not as debt. A performer executes the work. Outcome proof is submitted as a measurement hash, audit report, sensor log, satellite imagery, or verification signatures. A verification module checks the proof against contract rules. Payment releases automatically on pass, and stays locked on fail.

The pitch proposes unit prices in O, calibrated to the water yardstick so the same rate means the same thing globally. Examples given in the published design: 45 O per ton of CO2 removed via direct air capture with audit class A verification, 10 O per kilogram of ocean plastic in a defined region and verification class, 18 O per surviving tree at 24 months with staged payments. The protocol, as Normand describes it, has authority to mint up to a budget cap but only creates coins when verification passes.

These are proposals, not deployed rates. The design explicitly states that no coins are created on business plans or partial milestones that miss the rules, and that funds stay locked for retry within scope or return to the restoration pool if verification fails.

Normand positions the codebase as open source and invites developers to clone, test, and submit pull requests. As of mid-2025, no independent audit of a restoration payout on the protocol has been published.

1. Public restoration offer on-chain with unit price and verification class
2. Performer accepts mission and executes work
3. Performer submits measurement: audit hash, sensor feed, satellite imagery
4. Verification gate; no proof, no mint
5. Automatic mintAndCredit on success to the performer wallet

The published restoration contract mechanics walk through each step in the founder’s own framing.

The Measurement Gap That Stays Open

The entire premise is pay only on proof, which makes proof the entire bottleneck. The CDR.fyi snapshot documents that DAC delivery is bottlenecked by capex and operational delay rather than monetization, and that even basic delivery monitoring at known plants remains incomplete: 1,186 tonnes delivered against over 2 million tonnes contracted, with Climeworks supplying 81% of those delivered tonnes.

Normand’s design flags four engineering problems it does not pretend to have solved. Gaming: any pay-for-X system invites fake X, and the answer offered is multi-layer verification, audits, bonds, and outcomes that are expensive to falsify. Immature metrics: start where measurement is already strong, including DAC tons at the meter, plastic at the weighbridge, and tree survival from drone and satellite imagery, then expand as tools improve. Oracle trust: prefer decentralized, invitation-based observation over a single rented API. Regulation: on-chain payout complements environmental law, and pilots can lead policy rather than bypass it.

None of these problems is unique to O Coin. They are the same problems the voluntary carbon market has wrestled with for a decade, from REDD+ fraud cases to the post-2023 crash in credit prices, which is why the IEA’s Net Zero Roadmap calls for annual concessional funding for clean energy in emerging market and developing economies to reach around $80-100 billion by the early 2030s. That figure is set by policy, not by a verification gate.

• Multi-layer verification to deter fake delivery claims
• Start where measurement is already strong: DAC tons, weighbridge plastic, satellite tree survival
• Prefer decentralized observation over a single rented oracle
• Pair with environmental law, not substitute for it

What Would Have to Be True

Three preconditions carry the bet. Water-pegged measurement has to update reliably across more than 142 currency lanes. The verification gate has to reject bad claims at volume, not just at pilot scale. And buyers of impact receipts have to exist beyond voluntary luxury demand, which CDR.fyi pegs above $500 per tonne for DAC.

What the design does not yet show, on the public record reviewed here, is a mainnet with live O Coin supply and active contracts, an independent audit of any restoration payout on the protocol, or a customer buying verified removal at the protocol-set price. The project sits in open-source code, published essays, and a pre-booking announcement. The cleanup machines O Coin proposes to fund are real and largely operational. The measurement infrastructure the protocol asks the world to trust is the same infrastructure that today’s carbon market still cannot reliably deliver.

Frequently Asked Questions

What backs O Coin?

Per Christophe Normand’s published design, 1 O is calibrated to the observed average price of 1 liter of bottled water in each fiat currency lane, so value comes from the measurement of that local price rather than from a scarce supply cap.

Has O Coin launched?

As of mid-2025 the project is an open-source code fork of Bitcoin Core plus published HackerNoon essays. An Instagram post dated August 31, 2025 announced pre-booking for September 6 or 7. No exchange listing or live mainnet for the water-pegged currency is documented in the sources reviewed.

How much carbon has direct air capture actually removed?

CDR.fyi’s 2025 market snapshot reports 1,186 tonnes delivered by 6 DAC suppliers since 2023, with Climeworks supplying 81% of delivered tonnes, which is 0.05% of the over 2 million DAC credits contracted since 2022.

Is the voluntary carbon market working?

The World Bank’s 2026 State and Trends of Carbon Pricing reports credit issuances rose 8% from 2024 to 2025 while prices declined slightly across the year. Sylvera reported high-quality ARR credits at $26 per tCO2e in December 2025, up from $14 at the start of the year, a quality split rather than a broad market recovery.

How big is the climate finance gap?

The IEA’s Net Zero Roadmap states annual clean energy investment worldwide needs to more than triple by 2030 to around $4 trillion. The Climate Policy Initiative’s 2025 Global Landscape report cites an average need of $9.2 trillion per year from 2031 to 2050.
