I like the mission of this project. But I don't understand why the founding team has chosen to deploy its own blockchain instead of creating an application layer on top of an existing smart-contracts-capable blockchain (e.g. Ethereum)?

While I can see the advantages of using an existing blockchain solution (improved security through a larger mining pool, interoperability with other apps/contracts, better development focus on the application layer instead of infrastructure layer), I fail to see the benefits of creating yet another blockchain for CREA.
