Well I already reported that I am inventor of crypto-currency and why it was invented.
This time it is next stage of crypto-currencies development. Crypto-currency of new type the centralised one.
I reported it are 4 more persons involved into Bit-Coin, except me. Two of those who suggested to separate barter exchange index as currency, and after to make that Independent Electronic Money simple and simple and to shape as simple as Bitcoin, also analysed my suggestions to make crypto-currency to be national currency.
They one of them shaped the next plan.
No block-chain. (At least not strict need in it.)
No peering network. (Even if it is, it is only optional.)
An official regulator (for you the REGULATOR) issues money as monetary data structures (for you Monet) enciphered with unique identifiers of each of them with attached information as value. They are actually analogues of banknotes with different nominal values, and it is no need to divide them as blocks in block-chain. And they may be direct replacement of banknotes with same values.
Regulator shell exchange them on demand for real banknotes.
When it is a payment the Regulator registers each transaction (possibly for some fee as big as necessary to prevent the DDOS attacks.) But the registration of transaction does not reveal Monet identifiers for the Regulator, only registers the fact of transaction, possibly trough the anonymization.
The appropriate information history of all the transactions is stored in the Monet not in Regulator's database. Regulator basically has only confirmations for each, and spreads them confirmation base demands. During the Monet is transferred, each stage of its transactions shell be checked in base, for possible double transaction, if it is, the final code is not is not given, the fact of check is stored. And in this case it is not necessary to reveal the entire code from Moneta history only some produced code resolving appropriate check from the base.
In case of some misunderstanding Regulator could take official formal or legal actions, if codes of a Moneta will be revealed to Regulator.
As soon as Regulator gets Monet, it deletes its history, from the base, as a result base of transactions will get much-much smaller then BitCoin.
Any where in the world any money could be transacted. They also resolve mixers to be used.
The amount of electronic version of national currency may be regulated to be not grater then some amount. But it may be enough to replace that amount which typically refilled with dollars.
