Vault seems interesting. Any ideas on the fees etc? or is this totally opensourced/free?
All the normal features are going to be completely free.
Vaults business model is based around our "bankroll as a service", which we charge a commission on. We let apps (or casinos) place a bet against our crowd-funded bankroll, and offer a 50-50 profit share with the app on every bet. That is to say, when a player's bet wins, the bankroll investors completely pay for it; and when a player bet loses, the bankroll investors are given a half-kelly worth of money, and the rest is shared 50-50 between the app/casino and vault. On a low edge game (a half-kelly), the profit share for both vault and the app will be 0 (meaning it's effectively a free service), on a high-edge game the application and vault will have something to share.
Of course, that's an optional service and no one has to use it.
The other for-fee service that vault has, is (an optional, non-default) "Cold Addresses", which are deposit address that are not connected to the hot-wallet, but rather deep cold storage. They're designed to be impervious to any blockchain analysis, as the funds just sit in an cold address for as long as possible, and only ever taken out as a very last resort. It's an ideal service for someone who wants to deposit money from somewhere like coinbase that might ban gambling, or otherwise wants financial privacy. For this, we deduct a 1% fee from any amount deposited (this is only to make the service viable, otherwise everyone would use cold addresses and it would become a de-facto hot wallet).
@RHavar what does it mean pure bitcoins? how about some player wants to play and has no bitcoins? will and can Vault handle this ?
It means vault is purely scoped to dealing purely with bitcoins (e.g. we don't anything to do with fiat, altcoins, precious metals etc.). If someone wants to play, and doesn't have money it will be completely up to the application the uses vault. Perhaps they'll have a trial mode, allow the person to bet with 0, or have a faucet/chat bot.
