A hash-chained carbon credit registry where double counting is impossible by construction — and anyone can verify every credit, transfer and retirement.
On-chain carbon credit registry with AI pre-issuance verification and SHA-256 metadata anchoring — making double counting impossible.
An open-source registry that lets mangrove-restoring communities in Benin earn verifiable credits: no double counting, two-source evidence, human validation and a contract-enforced community share.
River data connected to a transparent, rule-based flood-aid fund.
Mizan proves factory emissions for EU CBAM: post-quantum signed meters, AI tamper detection and on-chain anchoring create certificates that can't be faked or claimed twice.
When a registry freezes a carbon project, its credits keep selling. Recourse proves the registry's own status on-chain and refuses, impairs and refunds downstream, with signed AI evidence.
Deterministic double-counting detection for carbon registries — every finding carries its evidence, and every report is hash-anchored so anyone can verify it was never altered.
Forest carbon credits get over-issued, get issued twice, and outlive the forests. CanopyChain checks every forest from orbit and records every credit on chain.
GreenGrid turns every solar panel, battery, EV charger and building in a district into an active participant in a fair, local and physically safe energy market.
An AI-powered blockchain wallet for secure crypto transactions, smart insights, risk detection, and effortless digital asset management.
AI-powered carbon accounting, from bills to a certified GHG inventory, reduction plans, SEMA and GRI reports and retired credits, with every step backed by an immutable proof on the blockchain.
Emissions you can verify. Claims you can defend. Tamper-evident CO2e ledger + carbon-credit registry, with the double-counting guard enforced on-chain by a verified smart contract.
Forest carbon credits, checked from space before they're sold. Satellites measure the forest, a smart contract decides how many credits can exist, and the same land can't be sold twice.
Verified carbon passports for the EU border. AI prepares the evidence, an accredited verifier signs, and smart contracts make double counting of low-carbon tonnes impossible.
When your crypto wallet shows you a balance, it asked a server, the server answered, your wallet drew the answer on the screen. Nullius asks for a cryptographic proof and checks it in your browser.
AI maps flood damage and cut-off villages from free satellite data; anyone can re-run it to verify, and a smart contract pays relief only once the report is confirmed on-chain.
AI flags unusual environmental readings, while blockchain fingerprints help detect changed records—supporting more transparent climate monitoring.
Finds carbon credits counted twice: serial-level checks for double issuance, retirement and claiming, plus verifiable Merkle claim receipts and a contract that blocks double retirement.
Satellite-checked carbon claims, recorded on-chain: an AI vegetation score gates credit minting, and a Sepolia registry blocks double counting of the same land.
An end-to-end dMRV engine combining physical solar irradiance and statistical AI anomaly detection with EVM smart contracts to eliminate greenwashing and mathematically prevent carbon credit double.
A verifiable carbon receipt for every AI request. Edit one number and the receipt is rejected.
Review solar records. Enforce meter-hour uniqueness. Verify the evidence.
Pay for forests that are still standing: escrowed climate funding released each year by satellite-verified canopy survival, with verifiers who lose their stake if they lie.
