In some business scenarios, user is needed in the first operation system using the target resource in the second operation system
When, it is necessary to resource transfers are carried out, target resource is transferred to the first operation system from the second operation system.
It is insincere due to being considered as mutually between the second operation system and the first operation system；Therefore in order to solve insincere industry
Resource transfers between business system, can construct corresponding business block chain using block chain technology, and will occur in business
Business datum chain carries out depositing card.
However for business as resource transfers, it is understood that there may be certain limitations, such as resource to be transferred are related to user
Privacy, then in order to avoid privacy of user leakage, such resource is not suitable for direct cochain and deposits card.Therefore, how block is based on
Chain realizes that the resource transfers between insincere operation system are known as urgent problem to be solved.
For example, user is after preferential platform is got for the discount coupon of some commodity in online shopping mall, in online quotient
Consume discount coupon in city.Since preferential platform and online shopping mall are different platform, between user, online shopping mall, preferential platform
Form three insincere domains.The discount coupon is stored in preferential platform, and user can have operating rights to the discount coupon of oneself
Limit, such as check and write off, withdraw deposit, recycle.
If this discount coupon consumption service using block chain technology realize if, due to discount coupon cannot directly cochain deposit
Card, therefore discount coupon cannot be carried out on chain and check and write off to reduce.So how to be assured for the discount coupon that user shows, it is ensured that
Online shopping mall can accurately deduct when carrying out discount coupon consumption；And how to avoid the discount coupon malice weight of not cochain
Multiple deduction is problem to be solved.
In this specification embodiment, provide a kind of resource transfers scheme based on block chain, for user resource without
The case where direct cochain of method deposits card, the second operation system (operation system i.e. where resource) can provide in advance for the target of user
It is assured in source；Pass through pair between the digital digest and corresponding target data token for storing target data in block chain
The mode that should be related to deposits card indirectly；The target data token is the voucher that the second operation system assures user resources validity.
Specifically, when being needed in the first operation system as user using the target resource being located in the second operation system, by using
The target resource token whether there is the corresponding number of target resource token by block chain query by the first operation system
Abstract；If it does, illustrating that target resource is necessary being, and then target resource is obtained to the second operation system, by second
The target resource of user is transferred to the first operation system by operation system.In this way, the not direct cochain of immediate targets resource deposits card,
It can use the corresponding relationship between the digital digest and corresponding target data token that store target data in block chain
Mode deposits card indirectly, to realize the resource transfers in different business systems (between i.e. insincere domain).
In order to facilitate difference, the operation system for storing the target resource that user is worth is known as the second business in this specification
System；The operation system being directed to when by user using target resource is known as the first operation system.
With above-mentioned discount coupon, this resource is illustrated, and preferential platform can be understood as the second operation system；Online shopping mall
It can be understood as the first operation system.
The block chain described in this specification can specifically include privately owned chain, shared chain and alliance's chain etc., in this theory
Without being particularly limited in bright book.
For example, in one scenario, above-mentioned block chain specifically can be by total portion mechanism, branch, agency etc.
Alliance's chain as allied member's composition；The operator of alliance's chain can rely on alliance's chain, corresponding to dispose
Business；And described above as total portion mechanism of allied member, branch, agency it all can serve as above-mentioned business
A service node.Each service node can will be produced by itself or the information relevant to business that receives is to trade
Form issued in alliance's chain, and joining after the common recognition processing of the common recognition node in alliance's chain in the transaction
Distributed data base in alliance's chain is stored, and " cochain " for completing above-mentioned Transaction Information deposits card.
Wherein, it should be noted that transaction (Transaction) described in this specification refers to and passes through block
The client of chain creates, and a data for needing finally to be distributed in the distributed data base of block chain.
Usually there is point of the transaction of narrow sense and the transaction of broad sense in the transaction in block chain.The transaction of narrow sense refers to use
The value Transfer that family is issued to block chain；For example, transaction can be user and exist in traditional bit coin block chain network
One initiated in block chain transfers accounts.And the transaction of broad sense refers to the industry being intended to business that user issues to block chain
Business data；For example, operator can build alliance's chain based on actual business demand, rely on the deployment of alliance's chain it is some with
Unrelated other types of line service (for example, depositing card business, fake certification business etc.) of value Transfer, and in this kind of alliance's chain
In, transaction can be the service message or service request with business intention that user issues in alliance's chain.
Above-mentioned client may include any type of underlying services data stored using in block chain as data branch
Support, to realize the upper layer application of specific business function.
In block chain technology, block chain interior joint carries out operation to block and usually requires to rely on corresponding intelligent contract
(Smart contract).Such as the operations such as storage, modification, deletion are required to rely on intelligent contract in block chain.The intelligence
Can contract can be it is a kind of be intended to apply contract is propagated, verified or executed in a manner of information-based can be deployed on block chain
Computer protocol.By stating that service logic may be implemented to execute corresponding operating in intelligent contract.Intelligent contract allows
Do not have to carry out credible transaction in third-party situation.These transaction are traceable and irreversible.Intelligent contract, which is capable of providing, to be better than
The safety of traditional contracts method, and reduce other transaction costs relevant to contract.In general, intelligent contract can be and be deployed in area
Block chain node is local, can call corresponding intelligent contract when node needs to be implemented some movement, run intelligent contract with
The service logic stated in intelligent contract is executed, to obtain implementing result.
