BitShares has an average of 300% decentralized collateral backing BitUSD. That's collateral without centralized counterparty risk.
I'm also well aware of examples like e-gold. No central point of failure is an advantage but is not an excuse for not having decentralized reserves too. Ironically the majority of cases, where centralized funds are lost, like Gox, are not a validation for NuBits but rather a warning as to why you shouldn't buy NuBits.
Any system without decentralized proof of reserves requires you to trust audits/incentives/good intentions. Blockchains with their decentralized ledgers and decentralized systems of control solve this and allow you to verify your funds & collateral are accounted for and secure.
As I said earlier, without decentralized proof of reserves, NuBits has used decentralization & the fantastic invention of the blockchain not to better protect customer funds than say a Bank/Mt. Gox but has instead used it to decentralize the role of the owners of those fractional reserve systems who will be unable to reimburse customers in the event of large redemptions.
Deja vu. Again we go back to the reserves. I'm almost tempted to let you prove the existence, location and custodians of the "300% decentralized collateral backing BitUSD" but I really don't care since this topic is not about BitUSD (whatever that is).
And what the hell has mtgox to do here with anything?
It is clear that much of the confusion arises from the definitions of the terms such as:
- reserves
- decentralized reserves
- decentralized vault of reserves
- decentralized proof of reserves
- decentralized systems of control
So when you prepare your next reply, please take time to provide me with a rigorous definition of those terms. I would also like to remind you that in the context of NuBits the conventional notion of reserves is irrelevant and there's a good reason for that.
The so called reserves are paralyzed wealth --- they just sit somewhere safe (hopefully), doing nothing. The clever concept of NuBits, however, uses those reserves to provide liquidity. If at some point audit is needed, it can easily be arranged. By cryptographically signing a message with the private keys that store the wealth held by liquidity providers their individual solvency can be verified.
Having said that, we see why the term reserves is not appropriate in the context of NuBits. Thus, an attentive reader could easily conclude that the term fractional reserves doesn't really apply to NuBits either.
