Interesting idea, looks like a usage token platform with masternode, mining farm as basis right ?
I wonder how proof of time works since eth is block based
It is similar to a masternode, your TimeMint though will exist in your ETH address and so it can stay in your cold wallet. There is no need to keep you machine on.
The other difference with masternodes, is that you will be able to sell a TimeMint through a smart contract,
only 3,333 TimeMints can exist.
That sounds like good way for making money passively. I wonder how market for TimeMint will work ?
