Background technology
Block chain contract in quantum catenary system focuses on practicality of the contract in business community, in quantum catenary system
Contract may may require that with the data in society to do interaction.The execution of contract needs to inquire about outside chain in quantum catenary system
Data, data are obtained outside chain can supply data the system, program, technology mechanism of block chain contract.In addition, all bases
It is required for all nodes to perform identical intelligence contract code in the intelligent contract of block chain, also result in intelligent contract can spend
Huge computing resource, also become abnormal expensive.It is urgent to create one kind in quantum catenary system in view of purposes in practical commercial
The execution mechanism of contract under chain, to solve the acquisition methods in authentic data source.
The content of the invention
In view of this, the present invention provides a kind of authentic data source for the distributed network for solving or partly solving the above problems
Implementation method.
To reach the effect of above-mentioned technical proposal, the technical scheme is that：A kind of authentic data of distributed network
The implementation method in source, includes following steps：
It is intelligent contract and the entrance of external data to obtain data to take Oracles, Oracles from intelligent contract, is connected
The block chain account book of Quantum Chain and outside mechanism；
Specifically, Oracles uses json file data storages, and the current exchange rate is included in data；
Create Oracles and be divided into two steps：
The first step, create Oracles transaction；
Second step, block chain is write by data file and stored；
The establishment of Oracles transaction needs：
Type of transaction (transactionType), it is respectively used to create transaction；
Oracles supplier (oracleProviderId), store the public keys of the Oracles owners；
OracleId, for exclusive status differentiation；
Create-payment, the payment for Oracles；
Fee-collection-ricipient, for the specifically used of Oracles；
DataHash, for depositing the hashed form of specific data；
Oracles data file includes two parts：Data and proof scheme；The process for reading and writing Oracles is as follows：
Intelligent contract does not allow directly to contact with outside by block chain account book, before intelligent contract reads data,
Oracles must write data into block chain account book；After Oracles is created, it is possible to be written to new data, Ke Yizhou
Phase Oracles is write；For same part data, there may be multiple copies, periodically carrying by Oracles
Donor is given；
During reading, data only are included in Oracles reading file, in the absence of proof scheme；Created in Oracles
During data be verified scheme and checked, if data, not by checking, transaction is not received, and write operation is not also permitted
Perhaps；
Oracles reliability depends on two conditions：The mandate of definite data service time and data；
Oracles has delay to provide a data, will not provide data, an Oracles and hold always for the processing mode of data
Data and intelligent contract can be impacted.
The present invention useful achievement be：The invention provides a kind of side that data are obtained outside Quantum Chain block chain account book
Formula, quantum catenary system manage the identity information of participant by intelligent contract, to be supplied based on the financial service of quantum catenary system

Embodiment
In order that technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Drawings and Examples are closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention, can realizes that the product of said function belongs to equivalent substitution and improvement, include
Within protection scope of the present invention.Specific method is as follows：
Embodiment 1：Oracles
With json file data storages, the current exchange rate is included in data.Oracles supplier, which possesses, writes function, can
Think any object.Create Oracles and be divided into two steps：1. create Oracles transaction 2. writes block chain by data file
Storage.The establishment of Oracles transaction needs type of transaction (transactionType), Oracles supplier
(oracleProviderId)、oracleId、create-payment、fee-collection-ricipient、dataHash,
Be respectively used to create transaction, the storage public keys of the Oracles owners, exclusive status differentiation, oracle payment,
Oracles specifically used, the specific data of storage hashed forms.
The read-write of data in Oracles
Intelligent contract do not allow by intelligent contract account book and with external contact.Before intelligent contract reads data,
Oracles must be by this write-in account book.After Oracles is created, it is possible to be written to new data.Oracles write-in
The process of block chain such as Fig. 1.Oracles can be write periodically.For same part data, there may be multiple pairs
This, is periodically given, process such as Fig. 2 by Oracles supplier.
Oracles data file：Include two parts：Data and proof scheme.During reading, Oracles
Data only are included in file, in the absence of proof scheme.Data are verified scheme and checked during Oracles is created,
Do not received if data are unsatisfactory for transaction, write operation is also not allowed to.Oracles supplier can only be adapted to it is artificial,
Readable.
Oracles reliability
Intelligent contract relies on Oracles and makes financial decision, it is therefore desirable to meets that definite data give time, data
Authorize two conditions.
Oracles has three kinds of methods for data：Delay provides a data, will not provide a data, Oracles mono-
Directly hold data and intelligent contract can be impacted.If data are given in Oracles delays, then the exchange rate may occur
Change, particularly intelligent contract for the exchange rate it is very sensitive in the case of.Oracles be a kind of connection quantum block chain account book with it is outer
The bridge on boundary, it allows leader's event of intelligent contract from intelligent contract block chain to obtain the information about the external world.
Oracles is to obtain the approach of data from the external world for intelligent contract.Intelligent contract can not pass through block chain account
This interacts with the external world, if can interact, may bring safety problem.Before intelligent contract reads data,
Oracles has to data writing into account book.
Intelligent contract is made to depend on data when finance determines, intelligent contract must confirm to the correctness of data.
The data provided during Oracles are built to be used to be written on account book.Each checking by the data of Oracles write-ins by plan, only
It is verified, can be just passed.This process is used for the correctness for verifying data.
Oracles supplies mechanism
The time of data supply can impact to intelligent contract, and derivative may be by the change of underlying assets
Repeatedly as important foundation.The 10% of daily bit coin total amount there may be change repeatedly, for this change repeatedly, it is necessary to
Unpredictable border is violated to call.When the arrival of consumer data predicted data, Oracles can change plan parameters in detail.
The specification of Oracles data supply mechanism is described as follows：
Embodiment 2：In quantum catenary system, Oracles data can be that Json file form is being created and deposited
Storage.
An Oracles data file example is as follows：
{
rate:{
"USD/EURO":"1.10351",
"USD/GBP":"1.31930",
"USD/JPY":"0.00954"
}
This is the example for the interest rate that an intelligent contract is quoted.It can be cited in intelligent contract：
function unlock(oracles,inputs){
if(oracles.currency.rate["USD/EURO"]>1.10){
//make decision#1
}else{
//make decision#2
}
In view of safety factor, intelligent contract will not directly invoke the data of outside, before intelligent contract reads data,
Oracles needs corresponding data to be written in open account book.
We to create Oracles, can be divided into following by Oracles " create and merchandise " in quantum catenary system
Two steps
1. by OracleCreat Transaction, a transaction is initiated；
2. write data into open account book.
Oracles creates transaction
{
"id":"hash of transaction,excluding signatures",
"transactionType":"oracleCreateTransaction",
"oracleName":"nameOfOracle",
"oracleProviderKey":"MyuemkT4raRPPjhDwd9MyzbBNt9QAwKHc",
"oracleId":"oracle_MyuemkT4raRPPjhDwd9MyzbBNt9QAwKHc"
"creation‐payment":"transactionId",
"name‐payment":"transactionId",
"fee‐collection‐recipient":"@oracleProviderAccount",
"dataHash":"MyuemkT4raRPPjhDwd9MyzbBNt9QAwKHc",
}
s:
In order to issue new assets, asset owner must pay following kind of payment：
|#|Payment|Value|Obligatory/Mandatory|Description||-------|--------
|--------|--------||1|Issue Payment|10,000-Fiat.USD|Mandatory|Payment for
issue new asset|2|Name Payment|specification|Mandatory|Payment for name of
the asset|3|Collateral|-|Optional|Mandatory for asset rate decline risk
Because assets payment can attract the player that those do not have resource to support assets properly, it can not be just
Preferably.Assets Problems are never only a very cruel game, but serious business.Asset owner must manage from the beginning
Assets Problems are solved, and prepare to spend to support this assets.Therefore, we will create inlet obstacle, and system attractive will be allowed to only have
The investor of powerful assets is issued in powerful preparation.
Pay title and assets name authority is described in detail.Mortgage payment makes user more trust assets.
The preferred embodiments of the invention is the foregoing is only, is not limited to the claims of the present invention.
It is simultaneously described above, for those skilled in the technology concerned it would be appreciated that and implement, therefore other are based on institute of the present invention
The equivalent change that disclosure is completed, should be included in the covering scope of the claims.
The present invention useful achievement be：The invention provides a kind of side that data are obtained outside Quantum Chain block chain account book
Formula, quantum catenary system manage the identity information of participant by intelligent contract, to be supplied based on the financial service of quantum catenary system
Preferably support, on this basis, devise Oracles, the intelligent contract of block chain can be allowed actual, more meet business and advise
Then, built from real world to the bridge block chain.
