The buyer / seller / product relationships for all commerce sites can be specified in a commerce category tree and documentation for financial exchanges can be linked as a source media node. Rather than relying on easily manipulated site reviews and trust algorithms, we can rely on our own personal trust networks for filtering. Both sides of a transaction are far more likely to behave responsibly if there is a personal trust network linking them. Local or specialized merchants can create constellations to link each other together in a trust network as well, adding another local layer of accountability, local control over industry and the ability to allow regional diversity for local laws or customs.
While anyone can create a global galaxy of all the constellations for a particular industry, similar to Uber, Airbnb, Ebay or Alibaba, the fact that anyone can do it removes exclusive control from the galaxy creators. Without control over the data, galaxies are simply a tool for end users, allowing them to filter and sort data across multiple constellations. The software applications become simply that, applications which input selected data from galaxies or constellations and provide some front end functionality such as paying a taxi driver or buying a product.
