Will HTR be formulating its own oracle solution? Or would Hathor utilize existing solutions with multiple projects/partners?

When Hathor started and even developed the initial version of Smart Contracts, they had their own solution. Hathor still intends to support that, but also add other options.

Decentralized oracles are obviously a trend at the moment, but there are also interesting solutions such as Coinbase price feeds and Open Price Feed modelIdeally, Hathor wants to be able to support multiple types of oracles and the users can choose what’s best for them
