Looks like an interesting coin. Wondering if I should join the campaign. But I'm a little iffy over the fact that it needs Bitcoins to work. I know it will be a while, but what happens once thouse Bitcoins run out?
At 25 cents per KMD the mined amount will cover the costs of the notary nodes, so the subsidy is not expected to last forever.
The BTC txfee costs will be less than the costs for the notary nodes.
I want to have at least a 10 year buffer, so for all that are complaining that we are raising funds or it is some sort of greed, they need to realize that it costs BTC to pay continuous BTC fees and to have many high end servers.
Once it is in place, it becomes a barrier to entry. Granted anybody else could fork the code, but still the entire notary nodes have to be reproduced and the BTC for txfees would be needed. Also, once KMD is live, people can just use KMD and obtain the benefits of being secured by BTC (indirectly) at a fraction of the cost.
Each user of KMD will create demand for KMD, usually on a continuous basis, and that will provide a base of demand. We will be migrating the various NXT assets to assetchains, which will use dPoW so there will be some reference cases available. By using KMD to secure the assetchains, for a minimal cost, each asset will obtain BTC level security for its transactions and not be a derivative crypto at the mercy of some master chain. the txfees for users would be denominated in that asset and the asset issuer would just need to purchase enough KMD to pay for the service.
Beyond assetchains, there will be smart chains which are special purpose blockchains that implement a dapp. think of it like an ASIC that does one thing and only one thing, vs a CPU that is running and OS and doing many things at once. We expect this to be a very popular way to utilize blockchain tech and the isolation it provides combined with efficiency that is further secured by dPoW will hopefully make a good demand for KMD.
