Description
Technical field
The present invention provides a kind of dual accounts model of restricted circulation that can be supervised, and realizes that stable, limitation is fried on block chain
Make logical card economic solution speculate, with positive incentive.
Background technique
Existing public affairs chain technology, the digital cash of generation is realized by the algorithm of decentralization, not any
The value of the supervision of national government department and associated mechanisms, currency is entirely to set up by common recognition.
Such as: bit coin is according to algorithm, and limiting total quantity of money is 21,000,000 pieces, and the generation of currency is that node is needed to consume
Expense Hash calculates power and digs mine to obtain, and every one block of generation in 10 minutes, each block is from initial 50 btc of reward, then
Halved every 4 years.Since bit coin is the first digital cash, and total amount is limited, complete decentralization, as long as bit coin net
Network exists, and personal asset never disappears, therefore has good reserve value, referred to as digital gold, but bit coin
Itself value fluctuation be it is very big, the currency for wanting to make large-scale application of it is impossible.
Ether mill is also to give birth to eth by digging mineral products, and execute intelligent contract and need to expend Gas, and user is using ether
Mill is also to need to spend when applying.Same eth is also that the prices fluctuate much, therefore also lacks the base of large-scale application landing
Plinth.
To sum up, if it is desired to allowing block chain that can land application on a large scale, the existing logical card economic model of public affairs chain is all not
Reasonably, the digital cash for needing the price steadiness that one can supervise circulates in the application of block chain.
Existing widely applied stable coin, mainly legal asset mortgage type, representative: Tether(USDT).
The USDT of Tether company distribution is anchored as the precedent for stablizing coin, ideal money and dollar 1:1.In other words,
The logical card of one USDT of the every purchase of user, Tether company can all increase by one dollar of fund reserve in its account.Work as user
When needing to exchange dollar, Tether will destroy corresponding logical card, and pay 5% service charge.The method is easily understood,
Process is simple.The assets of mortgage are as effective franc, not on block chain, avoid potential hacker attack.
The composition of internal USDT is divided into three layers:
Initial layer is bit coin public affairs chain: USDT itself is based on the number money for passing through Omni protocol issuance on bit coin public affairs chain
It produces.
The second layer is that Omni Layer protocol:Omni agreement can generate and destroy number on bit coin public affairs chain
Currency (USDT).The transaction of each USDT can be tracked and reported by Omnichest.info and Omnicore API.Together
Shi Xieyi ensure that USDT can be encrypted by Omni Wallet, the browser network wallet of a open source in secure anonymous
Environment in store and transaction.
It is finally Tether Limited: is the corporation de facto of Tether, they receives franc, i.e. dollar, then issue
The USDT of dollar mortgage.When user recalls guarantee, Tether can destroy corresponding USDT.All mortgage of Tether keeping are flowing
The franc of logical USDT.Publishing all auditing results simultaneously includes Proof of Reserves.
Proof of Reserves (PoR) is common recognition algorithm.Each USDT corresponds to one in Tether.Limited
Dollar.This means that the USDT quantity in system should be identical with the USD in Tether account.Because USDT is placed on ratio
Digital cash on special coin public affairs chain.Each transaction can be tracked.Therefore the USDT total amount of circulation can be found at any time.And
Tether then can periodically send Audit Report, inform the amount of money in user reserve.All transactions histories, the USDT of circulation
It can be found from Omnichest.info.
However, sacrifice is the decentralization that encrypts currency and should have while solving floating risk.Tether conduct
The U.S. dollar mandator of centralization, in fact it could happen that the problem identical as conventional banking facilities.Due to opaque, the camera bellows behaviour of information
Whether work, super generating are distributed indiscriminately and are difficult to avoid, therefore there is equivalent U.S. dollar quite to be disputed on on Tether account book.
USDT as coin is stablized, is realized in a manner of centralization, due to not supervising well, it is difficult to ensure that
USDT will not be distributed indiscriminately.USDT itself has good circulation, and price is also to be easy to receive the control of speculator, to generate
Biggish fluctuation, the maximum fluctuation of USDT be also be more than 20%.USDT as a kind of digital cash can decentralization circulation,
It is not supervised, this is unworkable at home.
Summary of the invention
