We will run a totally new network so certainly we wont use any other coins that already exist
In my world view, "If" safecoin ever exists, we can evaluate it and see if it works correctly, then make use of it
It's true I have seen that mining could be a waste of energy because constant competition and ever increasing electrical consumption; however, PoW is a solution that allows for decentralized database lock and verifiable write privilege. If we constrain the PoW to CPU only, we limit the centralization risk, and the power consumption requirement. This is an intention, CPU PoW. It is proven to work. Other systems such as PoS requires a stake to conduct block production, therefore identifiable participants.
Everything will be in one network, Items are similar to (coins) (equities), though they take description and price so that a market place can form. The plan is to promote one network, Safe Exchange Network.
Yes, I think its important in order to promote to developers, and also to have ongoing development funding, and also to reward our investors as originally intended.
I see the major difference is that we are going to have technology that works based on existing technology, however, we will fulfill a niche for a crypto marketplace and promote it how no one has ever made and promoted before.
