Example two
The objective of this embodiment is to provide a schematic structural diagram of a participant-based federation chain excitation system according to an embodiment of the present invention in fig. 1. As shown in fig. 1, the participant incentive system based on the coalition chain provided in the embodiment includes: a participant node cluster 1, a verifier node cluster 2, a sorting node cluster 3, and a TCE4. Transaction sequencer engine arrangement TCE (Transaction collator engine, abbreviated as TCE). The participant nodes, the verifier nodes and the sequencing nodes are in one-to-one communication connection.
As shown in fig. 1, the participant node cluster 1 includes a plurality of client nodes, and each client node may be a terminal device such as a smart phone, a tablet computer, a personal computer, and the like that initiates a transaction. Each client node in the enrollee node cluster is connected to the verifier node cluster 2.
The participants in the participant cluster generally do not store a complete blockchain copy, and are responsible for initiating a transaction request and receiving a request response result to connect with the verifier node cluster. The transaction request includes three types: an issue transaction, a reference transaction, and a price-polling transaction. An open transaction is a transaction initiated by a participant for uploading an asset (picture, video, file). A reference transaction is an authorization, access, download, etc. operation on an asset whose behavior may alter an account liveness score. The enqueue transaction is a virtual object in which a participant inquires about the verifier node about the additional transaction issuance cost to be paid according to the required uplink demand, and can be digital currency or other members in the alliance chain network.
The verifier node cluster 2 includes a plurality of verifier nodes, each node maintaining a blockchain copy storing state information for all accounts for auditing compliance of requests initiated by the participant nodes. Each verifier node in the cluster of verifier nodes 2 is connected to a cluster of participant nodes 1, a cluster of sequencing nodes 3, respectively.
And each node in the verifier node cluster stores a block chain copy, stores state information of all accounts, and updates the account book and the account state information when synchronizing the new blocks. When it receives a transaction request from a participant, it reviews the request. If the compliance checking and trial execution process is passed, the verifier node sends a successful response result of the request back to the participant, and submits the signed transaction request to the sequencing node cluster for recording in a newly issued block. If not, rejecting and sending the response result back to the participant.
The sorting node cluster 3 comprises a plurality of sorting nodes, and each sorting node can be deployed on a server for providing global sorting service of transactions and is responsible for selecting the transactions to be added into newly issued blocks. Each ordering node is connected to a respective verifier node cluster 2.
After receiving the transaction sent by the verifier node, the nodes in the sorting node cluster firstly check the signature of the verifier, judge the type of the transaction after checking, when the type of the transaction is not the price-inquiring type, put the transaction into a maintained transaction pool according to time sequence, when a new block is to be issued, operate TCE to provide global sorting service for the transaction in the transaction pool according to a preset rule, and sort the ordered transaction into a new block according to the block configuration, and then issue the new block. When the transaction type is the price inquiring type, the TCE is operated to obtain the estimated transaction release cost, the result is returned to the verifier node, and the verifier node sends the result back to the participant.
It should be noted that, when deployed, one node may play multiple roles.
In particular, the TCE4 provided in this embodiment may be configured in a sorting node of the coalition chain network, and the main functions are to provide global sorting services for transactions and calculate the release cost of transactions. TCE4 may also be deployed in a separate server in other ways.
Form of preset rules deployed in TCE: the method comprises the steps of obtaining an activity score of an account through an account address of an initiator of a transaction, comprehensively calculating a sorting value of the transaction, the existence time of the transaction in a transaction pool and the release cost of the transaction, determining global sorting of the transaction in the transaction pool according to the calculated sorting value, and encapsulating the front M transactions into blocks after determining, and releasing the blocks to a chain by a sorting node.
TCE has two main functions, the first of which is to determine the order of transactions according to a preset rule, and the second of which is to return to the participants the required release costs for the transactions, which may be digital currency or virtual objects approved by other members of the coalition chain network, according to a preset rule.

step S20, a participant initiates a request;
step S21, the verifier node receives the request initiated by the participant, performs compliance checking and trial execution processes, and proceeds to step S22 to judge whether the verification passes or not, and if the verification passes successfully, proceeds to step S23, the verifier node sends the transaction request to the ordering node. Otherwise, go to step S24 to return error information to the participant node and discard the error request;
step S25 is to check whether the signature of the verifier is correct, if the signature passes the check, the step S26 is to judge whether the transaction type is the price inquiry type, if not, the step S28 is to put the sorting nodes into the transaction pool according to the arrival time sequence of the transaction. When a new block is to be issued, running the TCE, selecting the first M transactions according to the running result of the device, packaging the first M transactions into the block, and then issuing the block, otherwise, executing the step S29 when the transaction type is a price inquiring transaction, and returning the issuing cost of the transaction request obtained by the sequencing node according to the preset rule of the device to a verifier node for sending the transaction to a participant by the verifier node;
finally, step S210 orders the nodes to broadcast new blocks into the network, where the nodes synchronize update blocks.

the sorting node cluster comprises a plurality of sorting nodes, each sorting node is deployed on a server and is used for providing global sorting service of transactions and is responsible for selecting the transactions to be added into newly issued blocks, and each sorting node is respectively connected with the verifier node cluster;
the transaction sequencer engine device is configured in a sequencing node of a alliance chain network or a separate server and is used for providing global sequencing service of transactions and calculating release cost of the transactions
Initiating data sharing transaction request information through a participant node;
the verifier node receives the request information and then verifies the request information, and after the verification is passed, the transaction request information is sent to the ordering node;
after receiving the request information, the ordering node judges whether the transaction type is a price inquiring type or not on the premise that the signature of the verifier node is correct;
if the price is not the price-inquiring type, the ordering node is firstly put into a transaction pool according to the transaction arrival time sequence, and when a new block is released, the first M transactions are selected and then packaged into the block for release;
when the transaction type is price inquiring transaction, the ordering node obtains the release cost of the transaction request according to a preset rule and returns the release cost to a verifier node for sending the transaction, and the verifier node sends the release cost to a participant node;
when a new block is released, operating a transaction sequencer engine device, selecting the first M transactions according to the operation result of the device, packaging the first M transactions into a block, and releasing the block;
the transaction sequencer engine device is integrated in the computer equipment of the sequencing node, and operates based on a participant alliance chain excitation mechanism when the transaction sequencer engine device operates, wherein the participant alliance chain excitation mechanism is as follows:
the number of times that the participants refer to the assets on other account chains in the participant behavior data is used as an index for adjusting the activity score of the participants;
when the ordering node operates the transaction sequencer engine device to conduct transaction ordering, the packing ordering sequence of the transactions in the transaction pool is determined according to a preset rule based on the activity score of the participants, the existence time of the transactions in the transaction pool and the release cost of the transactions;
if the participant is an account with high liveness score, the earlier the transaction ordering of the participant is, the faster the transaction ordering is uplink;
if the participant is an account with high activity score, the release cost of the transaction request is lower or even free according to a preset rule, and if the participant is an account with low activity score, the aim of quick uplink is achieved with high release cost;
when the transaction sequencer engine device is operated, the transaction sequencer engine device comprises:
extracting useful parameters related to the ordering from the external information;
respectively calculating to obtain the parameter values required by the next module according to the extracted useful parameters and preset rules;
comprehensively calculating the sorting value of each transaction according to the obtained parameter values and preset rules;
and descending order of all transactions is carried out according to the obtained ordering value.
5. The participant-federation chain incentive-based data sharing system of claim 4, wherein the client node is fused with the verifier node, implemented in the same terminal device.
