20150012370 | Virtual Tree System and Method - A website (“Teratrees”) is described where a person can upload pictures of trees or shrubs which they have recently planted and have them displayed in their personal profile. Validation of the tree is obtained by a voucher code that is entered into the website. Once the tree has been uploaded to the website it appears in the ‘Planted Trees’ section and can be offered to the Market at a price set by the planter. Another user can then purchase (using a virtual currency with real financial value) this tree from the Market and own it—whereupon it appears in their profile under ‘Owned Trees’. This is virtual ownership within the context of the website. The user who owns this tree can offer the tree again on the Market if desired, while further transactions are also possible. Users who plant and own trees are rewarded with points and ranking. | 01-08-2015 |
