Manifesto
Collecting Human Intention: A New Standard for Everyone.
Traditionally, art collecting felt like a closed circuit, reserved for deep pockets or academic expertise. The barrier to entry was high, and the fear of not knowing enough kept many people from owning something truly unique.
Carbono is here to change that. In an age where ~90% of online content is projected to be AI-generated by 2026, we believe the instinct to value human effort is universal. You do not need an art degree to recognize the deliberate stroke of a brush or the weight of a hand-carved object. You need proof.
Principle
Democracy Through Transparency.
We replace guesswork with visible process. Trust becomes understandable for everyone, not only insiders.
PoP
A window into the workshop, with technical milestones from start to finish.
HAC
An immutable digital deed that secures authorship and traceable ownership.
From Consumer to Custodian.
Collecting is no longer about hoarding expensive canvases in private vaults. It is about supporting human lineage. Whether it is a ceramic vessel for your home or a certified digital sketch, collecting on Carbono means investing in the soul of commerce.
Stop consuming objects. Start collecting intentions.
How It Works
Three Steps, Clear Trust.
1. Artisans Upload PoP
Makers publish milestone evidence from raw materials to final details, so you can review the creation journey directly.
2. Carbono Calculates HPS
The Human Proof Score reflects how complete and transparent the evidence is. A piece must reach 90%+ HPS before it can list — no exceptions, no self-reporting.
3. You Receive HAC
After purchase, you receive a Human Authenticity Certificate with ownership metadata and a blockchain fingerprint.
Trust Model
What HPS Actually Tells You.
HPS is simple to read: more C2PA-verified process evidence, higher score. A minimum of 90% is required to list — you only see work that has already passed the threshold.
Raw Material Verified
Evidence confirms the starting materials and first stage are human-led.

FAQ
Common Questions.
What is Proof of Process (PoP)?
PoP is a timeline of real creation evidence, like photos and videos captured at milestones. It helps you see how a work was made, not only how it looks in the end.
What does the Human Proof Score (HPS) mean?
HPS is a 0-100 score based on process evidence quality and completeness. A higher score means more transparent, traceable human labor behind the piece.
What is included in the HAC certificate?
Each purchase receives a Human Authenticity Certificate issued on-chain in your name — numbered, transferable on resale, and permanently linked to the full PoP archive. EARTH pieces carry one certificate. BIT edition slots are individually numbered on-chain.
Is Carbono only for collectors?
No. Carbono supports both collectors and artisans. Collectors buy verified work, while artisans document their process and keep 90% of every sale.
