At the moment, the guys just presented the idea. They do not have technical documents describing the project and the team is not represented.
Let's wait to understand what prometheus59 is.
Prometheus59 looks like a Dash/Ethereum hybrid, a masternode-based Proof-of-Work with smart contracts. How many of this type of blockchain network are already running? What differentiates Prometheus59 from the others that are already established?
Prometheus59 is a masternode-based PoS project with independent blockchain. There are some points, such as specific market pricing based on auction, specific way to determine payments for provided computing power, that can afford to differentiate P59 from other similar projects.
