MetaWorld Creators make things and the value of those things is determined by complexity and demand. Creations are submitted, and curation process begins.
During the process Creators are matched with builders who help to bring creations to life. Once a creation is functional it is placed on the block chain and given an initial value. There are static creations which depending on quality and demand will be given a totem value based on the block chain.
Here is an example: Let's say I made a Zelda-like figure using google blocks. A static object. I’d submit it to the community who votes on it. Votes are fed into an Etherium smart contract (block chain tech) where a value is created. Once the item has a value the creator can either place it in a market to sell or allow the system to hide it in world where value grows based on how long it remains hidden “totems”.
