How it works
From tree to currency, without cutting it down.
The landowner provides the trees, the company provides the money and the blockchain guarantees that every Buxo matches a real tree that is still standing.
Life cycle
Six steps, one living forest
- 1
Forest registration
The landowner registers their plots. Ownership and the area of every hectare are checked.
- 2
Inventory and verification
Trees are counted and geolocated, with their species and size, to estimate the CO₂ they absorb.
- 3
Buxo issuance
Each verified tree issues one Buxo on the blockchain, linked to its location and data.
- 4
Exchange
Buxos are bought and transferred. The landowner receives the money; the tree stays in the forest.
- 5
Offsetting
The company that wants to offset retires its Buxos and gets a traceable certificate of the CO₂ absorbed.
- 6
Monitoring
The forest is checked regularly. If a tree is felled or burns, its Buxo is no longer backed.
What's behind it
Every Buxo is backed by…
A tree with coordinates
Not a statistical average: a specific tree you can find on the map.
A registered hectare
Every forest is registered with its area and its owner verified.
A commitment not to log
The landowner earns while the tree stands, so looking after it pays off.
The technology
Blockchain: the forest's notary
The blockchain records every Buxo, every exchange and every offset publicly and in a way that cannot be altered. So nobody can sell the same tree twice or offset with a forest that does not exist.
Security
Immutable records: what goes in cannot be changed.
Transparency
Public transactions that anyone can check.
Traceability
Every Buxo leaves a trail back to its tree.
Energy use
Proof of stake: consumption comparable to ordinary servers, nothing like Bitcoin.
FAQ
What people ask us most
What exactly is a Buxo?
+
A digital currency (a blockchain token) backed by a standing tree in a Galician forest. Each Buxo is linked to its tree, its location and an estimate of the CO₂ it absorbs.
Why a tree and not a tonne of CO₂?
+
Because a tree can be seen and verified. Average absorption is around 167 kg of CO₂ per tree per year, but it varies with species, age and terrain: that's why each Buxo carries the data of its own tree.
What happens if the tree burns or is cut down?
+
Its Buxo is no longer backed, and this is recorded on the blockchain. That is why the model rewards landowners for keeping the forest clean and alive, which is also the best wildfire prevention.
Can I own a Buxo if I'm not a company?
+
Yes. Anyone can hold Buxos to offset their own footprint or simply to own their piece of Galician forest. There will also be a physical edition with a QR code.
Can I buy one yet?
+
Not yet. Obuxo is in development and Buxo has not been issued. Join the waitlist and we'll let you know when the first forests open.
