Fig. 2 shows according to the embodiment of the present disclosure in the exemplary mistake interacted between data outside block chain and chain
Journey 200.Example process 200 depict user intelligence and about 201, interactive intelligence and about 202, including trusted context 204
Data flowing between equipment 203 and data source 205.User intelligence and about 201 and interactive intelligence and about 202 can install with
It is deployed at the block chain node of the block chain network 100 such as Fig. 1, and can be called and be executed by node.From framework, in advance
Speech machine 206 includes front-end and back-end, wherein interactive intelligence and about 202 is used as prophesy machine front end, and equipment 203 is as after prophesy machine
End, the interaction outside block chain and chain between data (for example, data source 205) is realized by the interaction of front-end and back-end.Such as Fig. 2
Shown, process 200 includes: 1, executes user and Yue 201, when number outside user's intelligence in implementation procedure and about 201 request chains
According to when, generate request of data and simultaneously call interactive intelligence and about 202, interactive intelligence and about 202 suction parameter include that the data are asked
It asks, wherein request of data may include the address information of the outer data of chain；2, interactive intelligence and about 202 is executed, and by interactive intelligence
The address information of data is stored in the log of such as node outside about 202 recalls information and chain, and equipment 203 is led to
It crosses monitoring (for example, the regularly inquiring) log and recalls information and address information is passed into rear end；3, when equipment 203 by pair
The monitoring of log and when knowing the outer data of the request chain of user's intelligence contract on block chain, equipment 203 passes through trusted context 204
(for example, code is executed in trusted context) sends the data acquisition request of the outer data of chain for such as data source 205 etc
(for example, sending the data acquisition request to the equipment for including data source), for example, data source 205 may include by URL (system
One Resource Locator) and obtained from database data, obtained by search engine data, from other block chain (examples
Such as, from user's intelligence and about 201 where the different block chain of block chain) data or acquisition in any other way
Data；4, equipment 203 obtains data outside the chain of push from data source 205 by trusted context 204；5, equipment 203 passes through credible
Environment 204 passes data outside chain back interactive intelligence and about 202, for example, data outside chain are written in the log at node, so that
Interactive intelligence and about 202 can obtain the outer data of chain by monitoring (for example, regularly inquiring) log；6, interactive intelligence closes
About 202 push data outside acquired chain to user's intelligence and about 201.In addition, in order to guarantee safety, equipment 203 and outside

Row.In some instances, the channel of encryption can be determined according to the type of target data.In addition, can be can for data source 205
Letter data source.In the process 200, due to realizing data acquisition and transmission by trusted context 204, so that credible at one
Movement (for example, executing code etc.) is executed in environment, thus the safety of safety action and its data, integrality.Show some
It can be prophesy machine front end interactive intelligence and about 202 definition valuation interfaces, so that when calling interactive intelligence and about 202 in example
Call the valuation interface, the valuation interface be used for assess obtain different types of data needed for consumption voucher (e.g., including it is unlimited
In integral, expense etc.), need the prophesy machine mode of voucher that can guarantee that prophesy machine is stable, enduringly operation is gone down, for example,
It is realized according to different types of data from user blocks chain account to interactive intelligence and the voucher of about 202 block chain accounts turns
It moves.
The embodiment described according to fig. 2 provides the interaction enhanced outside chain between data and block chain by trusted context
Scheme prophesy machine can be enable safely, completely to obtain believable outside to realize the prophesy machine of the confidence level of enhancing
Data, it can be ensured that trust data source safety outside chain completely enters user's intelligence contract, realizes user's intelligence contract and outer
Authentic data interaction between the world, portion.

Step:
Step 401: the log at the node of block chain network is regularly inquired by trusted context.
Step 402: when the log inquired includes the calling letter of the interactive intelligence contract executed in block chain network
Breath, and the recalls information indicates that user's intelligence contract that the interactive intelligence contract is executed in the block chain network calls
When, address information associated with the recalls information is obtained from the log, wherein the address information corresponds to user intelligence
The target data of contract request being located at outside the block chain network.In this step, interactive intelligence contract and credible ring
Interaction between border (or equipment including the trusted context) is by the monitoring to the log at node (for example, regularly looking into
Ask) Lai Shixian, wherein log includes the recalls information and address corresponding with target data about interactive intelligence contract
Information.
Step 403: being based on the address information, target data is obtained from data source by the trusted context.
Step 404: the target data is fed to node by trusted context.
In some embodiments, which may include the security context provided by processor, such as by aforementioned
The creations such as SGX technology security context.
In some embodiments, step 403 may include: by the trusted context, via the channel of encryption to including institute
The equipment for stating data source sends the acquisition request for being directed to the target data；By the trusted context, via encryption channel from
The equipment receives the target data sent in response to the acquisition request.In this step, via the channel of encryption (for example,
Https channel etc.) realize the acquisition to target data, it is ensured that trusted context (or equipment including trusted context) and outer
The safety of interaction between portion's data source.
According to the embodiment that Fig. 4 is described, the interaction enhanced outside chain between data and block chain by trusted context is provided
Scheme prophesy machine can be enable safely, completely to obtain believable outside to realize the prophesy machine of the confidence level of enhancing
Data, it can be ensured that trust data source safety outside chain completely enters user's intelligence contract, realizes user's intelligence contract and outer
Authentic data interaction between the world, portion.
