Am an environmentalist we can start up a transparent project fund a tree using blockchain technology where by all trees planted and in existence can be put on a public ledger where everyone can see and audit in form of an inventory like a huge public accounting ledger that everyone can see, but can only edit their own data. So the ledger accounts for trees. Where by when a property owner registers his or her own trees on the ledger.The project will issue cryptocurrency based on the number of tree units the property owner claims. These tokens would go into an electronic wallet on a blockchain associated with the property parcel number. Each year, the resident would be issued more tokens by the project as their trees grow and the value of the tokens would be derived from climate data surveys there would be increase in token values, or decrease token value based on estimated growth rates where by When a person wants to cut down a tree, they need to spend tokens to do so. Ideally, A property owner would not cut down more than they can grow. If they don’t have enough tokens, then they need to buy them from adjoining neighbors who are also trying to grow more than they must lose this would reduce the rate of defforestation
