OXYGEN — Methodology

What the number means

The figure printed on a tree is projected capacity: what a mature tree of the species we plant should produce in a year. It is not a claim that this oxygen has been produced.

Projected, not produced

A sapling planted today approaches its figure over years, not days. That is why the wording sits next to the number on the mint screen itself rather than three clicks away — a truthful number on page four does not fix a misleading one on page one.

Where the number comes from

Each tier carries a fixed capacity from the table below, set in the contract. Once the species is chosen, that table gets tied to a documented per-tree figure from a peer-reviewed source or a USDA Forest Service / EPA methodology, cited here.

The maturity gap

We will publish the maturity curve for the chosen species — what share of full capacity is reached by year N — so the distance between what has been minted and what is actually growing is stated in years rather than left unsaid.

Not finalized. The species, the site and the contractor have not been chosen, so neither the source figure nor the maturity curve can be published yet. Everything below is the structure those numbers will land in — the tier weights themselves are already what the contract uses.

The six tiers

A rarer tier does not cost more — it carries a larger claimed capacity. The tier is drawn by the contract from the hash of a block that did not exist when the mint was submitted, so neither you nor we can steer it, and it is frozen once drawn.

This is a collectible, not an investment. What we plant, we publish. What we haven’t planted yet, we say so.
