The invention aims to provide a multi-chain data interaction method and a multi-chain data interaction system, wherein each sub-chain front-end only needs to interact once with a block chain middle station, so that the problems of high butt joint cost and low interaction efficiency caused by frequent interaction among different chain front-ends in the existing multi-chain interaction process are solved.

The invention considers that authorization is needed when some data are interacted in the same system, so that the block chain middle station is divided into a public data block chain middle station and a private data block chain middle station.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The first embodiment is as follows:
as shown in fig. 2, this embodiment provides a multi-link interactive data uploading method, where the method includes:
a1, acquiring the requirement of data to be interacted of each sub-chain by using a requirement pool;
each sub-chain only needs to divide the data which needs to be interacted with into two types: public data and private data. Each sub-chain puts the requirements of the sub-chain for data interaction into a requirement pool. Each demand belongs to a certain class of data of a certain class of service. For example, a demand needs to search for payment information of the household appliance service from 21 years to 3 months to 6 months. After being put into the demand pool, the demand is translated into some data for obtaining some kind of service. Which have been explicitly defined on the blockchain as being public data or private data.
A2, utilizing the demand pool to call the prepositions of the corresponding sub-chains of the demand according to the demand, and sending the data needing to be interacted to a block chain middle station; the blockchain middlebox includes a public data blockchain middlebox and a private data blockchain middlebox.
And the demand pool calls the prepositions of the corresponding sub-chains to send the data needing interaction to the corresponding block chain intermediate station according to a specified format. The specific process is as follows:
judging whether the data needing to be interacted in the demand is public data or private data by using the demand pool;
if the data needing to be interacted is public data, uploading the public data needing to be interacted to a public data block chain middle station in a public data mode:
searching the front of a corresponding sub-chain of the demand by using the demand pool, and pushing the demand to the front of the corresponding sub-chain;
acquiring public data needing interaction through the query contract interface of the corresponding sub-chain by utilizing the front of the corresponding sub-chain; the method comprises the steps that a front portion of a corresponding sub-chain receives a demand pushed by a demand pool, public data needing interaction of the corresponding sub-chain is screened, then the front portion obtains the public data needing interaction through a query contract interface of the sub-chain, each demand records needed service data, and each sub-chain has a corresponding relation with a certain type of service.
Marking the sub-chain from which the public data needing interaction is originated by using the prepositive mark of the corresponding sub-chain; when the public data to be interacted by the corresponding sub-chain is uploaded to a station in a public data block chain through the preposition of the corresponding sub-chain, the preposition of the corresponding sub-chain marks which sub-chain the data comes from;
uploading the public data needing interaction to a public block chain platform according to a standard format by using the prepositions of the corresponding sub chains; the preposition will assemble the public data needed to interact according to the standard data content format (1, service type 2, service time 3, service data content json string), and upload to the evidence storage contract of the public data block chain platform.
If the data needing to be interacted is the privacy data, uploading the privacy data needing to be interacted to a privacy data block chain central station in a privacy data mode:
searching the front of a corresponding sub-chain of the demand by using the demand pool, and pushing the demand to the front of the corresponding sub-chain;
acquiring privacy data needing interaction by using the prepositive position of the corresponding sub-chain through a query contract interface of the corresponding sub-chain; the private data is protected by a secret key; the front of the corresponding sub-chain receives the requirement pushed by the requirement pool, the privacy data which are required to be interacted with the corresponding sub-chain are screened, and the front of the corresponding sub-chain obtains the privacy data which are required to be interacted and protected through the inquiry contract interface of the corresponding sub-chain.
Marking the private data needing to be interacted from which sub-chain by using the prepositive mark of the corresponding sub-chain; when the corresponding sub-chain uploads the private data needing interaction to a station in the private block chain through the front part of the corresponding sub-chain, the front part of the corresponding sub-chain marks which sub-chain the data comes from;
and decrypting the privacy data needing to be interacted by utilizing the prepositive position of the corresponding sub-chain according to the key used by the current sub-chain and uploading the privacy data to a privacy block chain platform according to a standard format. The corresponding sub-chain is prepositioned to decrypt the private data according to a key system used by the corresponding sub-chain where the private data needing interaction is located, and the private data on the corresponding sub-chain is assembled according to a standard data format (1, service type 2, service time 3 and service data content json string). Plaintext uplink is carried out on two fields of service type and service time in the reassembled private data; and encrypting the data of the json string of the service data content according to an encryption algorithm and a key used by a corresponding sub-chain where the private data needing to be interacted is located. The corresponding sublink uploads the reassembled private data to a service contract of a station in the privacy blockchain.
The reason why the two fields of the service type and the service time are uplink in clear text is that when other child chains request data to the middle station according to the two dimensions of the service type and the service time, the middle station can filter the two fields and distribute the data to the corresponding child chains. The purpose of encrypting the data content json string by using the encryption algorithm and the key of the corresponding chain of the uploaded data is to improve the security, and the data content json relates to data security and needs to use a key system of the corresponding chain. After the sub-chains upload data to the middle station of the block chain, other sub-chains can conveniently acquire corresponding data.
Example two:
as shown in fig. 3, an embodiment of the present invention provides a multi-link interactive data uplink method, including:
b1, acquiring data content required by the child chain by using a station in the block chain; the required data content includes: three fields of required service type, service time and data source
And B2, transmitting the data required by the sub-chain to the corresponding sub-chain by using the station in the block chain according to the data content required by the sub-chain.
In particular, the method comprises the following steps of,
judging whether the data required by the sub chain is public data or private data according to the data content required by the sub chain by using the station in the block chain;
if the data desired by the child chain is public data, transmitting the public data desired by the child chain to the corresponding child chain in a public data mode:
and transmitting the public data wanted by the sub-chains to the corresponding sub-chains by utilizing the query contract interface of the station in the public data block chain. And a sub-chain sends parameters such as a data source, a service type and service time through the front-end of the sub-chain to call a platform query contract interface in a public data block chain, and the platform query contract interface in the public data block chain returns data required by the sub-chain.
If the data required by the sub-chain is private data, transmitting the private data required by the sub-chain to the corresponding sub-chain in a private data mode; when the private data is obtained, the corresponding data is obtained through the filtering of a bastion white list and a corresponding gateway, the verification of a key service and three fields of a service type, a service time and a data source, and the specific steps are as follows:
verifying the identity of the child chain by using a bastion machine; a sub-chain accesses a query contract interface of a station in a private data block chain through a front-end; these accesses are filtered through the bastion machine, passing only the corresponding whitelist ip. After being filtered by the fort machine, the identity contract is required to be verified; the identity information of the sub-chain is brought when the front of the sub-chain requests the inquiry contract interface of the station in the privacy data block chain, and the identity information is intercepted by the identity authentication contract before the inquiry contract interface of the station in the privacy data block chain is called. And judging whether the user group of the calling service type of the data-providing subchain contains the subchain or not, and if so, passing the verification.
After the verification is passed, transmitting the privacy data wanted by the sub-chain to the front of the corresponding sub-chain by using a privacy query contract of a station in a privacy data block chain; and returning the privacy data to the front of the corresponding sub-chain according to the fields of the data source, the service type and the service time of the sub-chain by the privacy query contract.
Decrypting the private data required by the sub-chain by using the prepositive position of the corresponding sub-chain through a private key to obtain decrypted private data; the front of the corresponding sub-chain calls a decryption algorithm of the key service data provider sub-chain through a private key (agreed by both parties and given off-line) of the data provider sub-chain, and the private data is decrypted to obtain decrypted private data.
And storing the decryption privacy data to the service contract of the corresponding sub-chain by utilizing the preposition of the corresponding sub-chain. The front of the corresponding sub-chain performs a series of logic processing on the decryption private data, so that the decryption private data becomes service data which can be directly stored in a contract, and then the front of the corresponding sub-chain can store the data required by the sub-chain in the corresponding sub-chain service contract.
Example three:
as shown in fig. 4, an embodiment of the present invention provides a multi-link data interaction method, where the method includes:
s1, uploading data needing interaction to a block chain middle station by using a plurality of sub-chains;

s2, utilizing a block chain intermediate station to uplink the data needing to be interacted according to the data content needed by the rest sub-chains;
the utilizing the station in the block chain to uplink the data needing to be interacted according to the data content needed by the rest of the sub-chains specifically comprises:
s21, acquiring data contents needed by the other sub-chains by using the block chain middle station;
and S22, transmitting the data required by the other sub-chains to the corresponding other sub-chains by using the station in the block chain according to the data content required by the other sub-chains.
Referring to fig. 5, the present embodiment further provides a multi-link data interaction system, including:
the interactive data uploading unit M1 is used for uploading data to be interacted to the block chain middle station by utilizing a plurality of sub chains;
the interaction data uploading unit M1 includes:
the requirement obtaining module M11 is configured to obtain a requirement of data to be interacted with by each child chain by using a requirement pool;

the data content obtaining module M21 is configured to obtain data content required by the remaining child chains by using the block chain middlebox;
a data obtaining module M22, configured to send, by using the station in the blockchain according to the data content required by the other sub-chains, the data that the other sub-chains want to the corresponding other sub-chains
When a system is used, there are many blockchains to serve, and there is traffic interaction between different blockchains. Different sub-chains can respectively place data needing interaction on a private data block chain intermediate station and a public data block chain intermediate station. As shown in fig. 1, the sub-chain 2 and the sub-chain n are mutually connected. Without the present invention, the blockchain preamble of each sub-chain needs to dock n-1 blockchain preambles, which is very complicated to dock. Under the condition of using the invention, each sub-chain is preposed and only needs to interact once with the middle station of the block chain. The invention considers that authorization is needed when some data are interacted in the same system, so that the block chain middle station is divided into a public data block chain middle station and a private data block chain middle station.
Because the services operated by each sub-chain are different, different types of data are distributed on different sub-chains, and the data of all different chains are synchronized relative to each sub-chain, the redundancy of the data is reduced, the storage space is saved, and the service coupling is also reduced. Meanwhile, when the chain needs to interact with the chain due to cross service, the invention avoids frequent interaction between the prepositions of different chains. The data stored in the middleboxes of the block chains in the same time zone indirectly provides evidence for interaction among different chains, and data can be conveniently supervised and audited.
The invention realizes that the data required by the chain can be obtained without synchronizing other chain data among different chains, the data stored in the block chain middle station indirectly provides a proof for the interaction among different chains, and the data is convenient to supervise and audit.
