In the following description, reference is made to "one particular embodiment" which describes a subset of all possible embodiments, but it is to be understood that "one particular embodiment" describes the same subset or a different subset of all possible embodiments and can be combined with each other without conflict.
Unless defined otherwise, all technical and scientific techniques used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.
Before describing embodiments of the present invention in further detail, the terms and terminology involved in the embodiments of the present invention will be described, and the terms and terminology involved in the embodiments of the present invention will be used in the following explanation.
(1) Transactions (transactions), which are equivalent to computer terms "transactions," involve operations that need to be submitted to the blockchain network for execution, and do not refer solely to transactions in the business context, which embodiments of the present invention follow in view of the convention in blockchain technology that the term "Transaction" is commonly used.
For example, a deployment (Deploy) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; call (Invoke) transactions are used to append records of transactions in the blockchain by invoking smart contracts and to operate on the blockchain's state database, including update operations (including adding, deleting, and modifying key-value pairs in the state database) and query operations (i.e., querying key-value pairs in the state database).
(2) A blockchain (Blockchain) is a storage structure of encrypted, chained transactions formed by blocks (blocks).
(3) A blockchain network (Blockchain Network) incorporates new blocks into a set of nodes of the blockchain by way of consensus.
(4) Ledger (Ledger) is a generic term for blockchains (also known as ledger data) and state databases that are synchronized with the blockchain. Wherein the blockchain records transactions in the form of files in a file system; the state database records transactions in the blockchain in the form of different types of Key (Key) Value (Value) pairs for supporting quick querying of transactions in the blockchain.
(5) A smart contract (Smart Contracts), also referred to as a chain code (Chaincode) or application code, is deployed in a node of the blockchain network, which executes the smart contract invoked in the received transaction to update or query the state database for key values.
(6) Consensus (Consensus), a process in a blockchain network for agreeing on transactions in blocks among the multiple nodes involved, the agreed blocks will be appended to the tail of the blockchain, and the mechanisms implementing Consensus include Proof of Work (PoW, proof of Work), proof of equity (PoS, proof of status), proof of equity authority (DPoS, delegatd Proof-of-status), proof of elapsed time (PoET, proof of ELAPSED TIME), and the like.

The type of blockchain network 101 is flexible and diverse, and may be any of public, private, or federated chains, for example. Taking public chains as an example, any electronic device of a business entity, such as a user terminal and a server, can access the blockchain network 101 without authorization; taking the alliance chain as an example, after the service body obtains the authorization, the electronic device (such as a terminal/server) under the jurisdiction of the service body can access the blockchain network 101, and at this time, the electronic device becomes a client node in the blockchain network 101.
In some embodiments, client node 104-1 may be implemented as a mere observer of blockchain network 101, i.e., providing functionality to support a business entity to initiate transactions (e.g., for storing data in the uplink or querying data on the link), and may default or be selectively implemented (e.g., depending on the specific business needs of the business entity) for functions of consensus node 102 of blockchain network 101, such as ordering functions, consensus services, ledger functions, and the like. Therefore, the data and the service processing logic of the service main body can be migrated to the blockchain network 101 to the greatest extent, and the credibility and traceability of the data and the service processing process are realized through the blockchain network 101.

The application layer 301 encapsulates various services that the blockchain network can implement, including tracing, certification and verification of transactions, etc.
Consensus layer 302 encapsulates the functionality of the mechanism by which nodes 102 in blockchain network 101 agree on blocks (i.e., consensus mechanism), transaction management, and ledger management. The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the like, and supports the pluggable of the consensus algorithms. The transaction management is used for verifying a digital signature carried in the transaction received by the node 101, verifying the identity information of the service entity 104, and judging and confirming whether the service entity has authority to conduct the transaction according to the identity information (reading related information from the service entity identity management); for the business entity that obtains authorization to access the blockchain network 101, all possess the digital certificates issued by the authentication center, and the business entity signs the submitted transaction with the private key in its own digital certificate, thereby declaring its legal identity. Ledger management is used to maintain blockchains and state databases. For the block with consensus, adding to the tail of the block chain; executing the transaction in the block with consensus, updating the key value pairs in the state database when the transaction comprises an update operation, querying the key value pairs in the state database when the transaction comprises a query operation, and returning a query result to the client node of the business entity. Supporting query operations for multiple dimensions of a state database, comprising: querying a block based on a block sequence number (e.g., a hash value of a transaction); inquiring the block according to the block hash value; inquiring the block according to the transaction serial number; inquiring the transaction according to the transaction serial number; inquiring account data of the service body according to the account (serial number) of the service body; the blockchains in the channel are queried according to the channel name.
The network layer 303 encapsulates the functionality of point-to-point (P2P, pointtoPoint) network protocols, data propagation mechanisms and data verification mechanisms, access authentication mechanisms, and service body identity management.
Wherein the P2P network protocol enables communication between nodes 102 in the blockchain network 101, a data propagation mechanism ensures propagation of transactions in the blockchain network 101, and a data verification mechanism is used to implement reliability of data transmission between nodes 102 based on cryptography methods (e.g., digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service entity joining the blockchain network 101 according to the actual service scene, and giving the authority of the service entity to access the blockchain network 101 when the authentication is passed; the service agent 104 identity management is used to store the identity of the service agent 104 that is allowed to access the blockchain network 101, as well as rights (e.g., the type of transaction that can be initiated).

The online exchange and extrusion process comprises a public security node, a check-out node, a guard node and a court node, wherein the public security node is a process starting node, the court node is a process ending node, other nodes are intermediate nodes, and an authentication center firstly determines that the current process node is the intermediate node.
Step 402: under the condition that the historical approval information of the historical flow node is obtained from the blockchain network, the current approval information obtained when the current flow node executes the corresponding flow is obtained.
The method comprises the steps that a node executing a process before a current process node is a historical process node, the historical process node uploads historical approval information to a blockchain network, after the current process node acquires the historical approval information of the historical process node from the blockchain network, the current process node executes a corresponding process to obtain the current approval information, and an authentication center acquires the current approval information of the current process node.
The current process node is a hospital node, the history process node is a public security node, the public security node uploads the exchange-press record information in the exchange-press process to the blockchain network, the hospital node acquires the exchange-press record information of the public security node from the blockchain network, and then the hospital node continues to execute the approval process to obtain the exchange-press confirmation information.
Step 403: current approval information is uploaded to the blockchain network.
After obtaining the current approval information of the current flow node, the authentication center uplinks the current approval information to the blockchain network, so that other flow nodes positioned behind the current flow node in the process of executing the flow can acquire the current approval information and process the current approval information.
Illustratively, the inspection station node links the exchange-extrusion confirmation information to the blockchain network, so that the exchange-extrusion confirmation information can be acquired by the attendant node and the court node, effective supervision on the exchange-extrusion confirmation information can be realized, and verification signature and other processing can be performed on the exchange-extrusion confirmation information.

If the authentication center confirms that the current flow node is a flow starting node, no history flow node exists before the flow starting node, and no history approval information exists, the authentication center obtains the current approval information when the current flow node executes the corresponding flow, and then the current approval information is uploaded to the blockchain network.
The public security node is a flow starting node in the online exchange-press flow process, and the authentication center acquires exchange-press record information of the public security node and then uploads the exchange-press record information to the blockchain network.
As an optional implementation manner, after determining the current flow node in the process of executing the flow, the method further includes: judging whether the current flow node is a flow ending node or not; if so, ending the flow when the history approval information of the history flow node is obtained.
If the authentication center confirms that the current flow node is a flow end node, no flow node exists after the flow end node, the flow end node plays a role in supervision, and serve of process batches of information are not needed to be sent to the blockchain network, when the authentication center determines that the historical approval information of the historical flow node is acquired, the supervision of the flow end node is completed, and the flow is ended.
The court node is a flow ending node in the online exchange and extrusion process, a previous node of the court node is a gatekeeper node needing to upload exchange and extrusion approval information, and when the authentication center confirms that the court node acquires the exchange and extrusion record information of the gatekeeper node, the court node finishes the supervision function, and the online exchange and extrusion process is ended.
As an optional implementation manner, before obtaining the current approval information obtained when the current flow node executes the corresponding flow, the method further includes: verifying the identity information of the current flow node; and under the condition that the identity information of the current flow node passes verification, executing the step of obtaining the current approval information when the current flow node executes the corresponding flow.
Before the authentication center acquires the current approval information obtained when the current flow node executes the corresponding flow, the authentication center needs to verify the identity information of the current flow node, and under the condition that the identity information of the current flow node passes the authentication, the authentication center acquires the current approval information obtained when the current flow node executes the corresponding flow, so that the security of the current approval information uploading block chain is ensured, and malicious acquisition is prevented.
Specifically, the authentication of the identity information includes; acquiring the attribute of the current flow node; and under the condition that the attribute of the current flow node is determined to be the target attribute, determining that the identity information of the current flow node passes verification.
The authentication center obtains the attribute of the current flow node, wherein the attribute can be the industry field, and when the authentication center determines that the attribute of the current flow node is the target attribute, the authentication center indicates that the current flow node is error-free, and the identity information of the current flow node passes the authentication.
Illustratively, the current flow node is a hospital node, the authentication center acquires the domain of the hospital node, and when the authentication center determines that the domain of the hospital node is the judicial domain, the authentication center indicates that the identity information of the hospital node is verified to pass.
Specifically, the authentication center receives public key information sent by the gatekeeper node, acquires a prestored certificate chain of the gatekeeper node from the blockchain network, matches the public key information of the gatekeeper node in the certificate chain with the public key information sent by the gatekeeper node, and determines that the gatekeeper node really belongs to the judicial agency node if the matching is successful.

The target node pre-stores a certificate chain in the blockchain network, wherein the certificate chain contains real public key information of the target node. The authentication center obtains a certificate chain of the target node from the blockchain network according to the intelligent contract.
The authentication center acquires public key information in the certificate chain, matches the public key information in the certificate chain with target public key information, and determines whether the target node is a judicial organization node according to a matching result. If the authentication center determines that the public key information of the target node in the certificate chain is successfully matched with the target public key information, and the target node is a judicial agency node; if the authentication center determines that the public key information of the target node in the certificate chain fails to match with the target public key information, the target node is not a judicial agency node.
