NaFT — Public Demo and Reproducible Engineering Evidence Released
NaFT has reached a major milestone for IEEE ClimateChain 2026.
I’ve published an English-narrated demonstration, an interactive browser demo, and an open-source repository with reproducible engineering evidence.
The project addresses a fundamental challenge in climate MRV:
When verification methodologies change, which historical claims need to be reviewed again, and why?
Recent milestones:
• Demonstrated selective re-verification across 100 synthetic climate claims. • Evaluated the impact analyzer against 614 deterministic adversarial changes, with zero false negatives within the tested synthetic state space. • Verified predecessor-to-successor evidence lineage on Ethereum Sepolia. • Passed GitHub CI and independent read-only Sepolia verification on the same source commit. • Published supporting scientific references and explicit research limitations.
NaFT uses blockchain to witness evidence provenance, not to certify environmental truth.
The goal is to make climate MRV more reproducible, explainable, and independently verifiable.

I’m particularly interested in feedback from researchers, climate MRV practitioners, and developers working on verification systems and environmental data integrity.
What do you see as the biggest challenge in maintaining trustworthy climate evidence when methodologies evolve?
