Example two
The purpose of this embodiment is to provide a schematic structural diagram of a participant-based alliance chain incentive system provided in fig. 1 according to an embodiment of the present invention. As shown in fig. 1, the federation chain-based participant incentive system provided by the present embodiment includes: participant node cluster 1, verifier node cluster 2, sequencing node cluster 3, and TCE 4. The Transaction sequencer engine device TCE (Transaction queue engine, TCE for short). The participant node, the verifier node and the sequencing node 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 smartphone, a tablet, or a personal computer that initiates a transaction. Each client node in the participant node cluster is connected with a verifier node cluster 2.
Participants in the participant cluster do not generally store complete block chain copies, and are responsible for initiating transaction requests and receiving request response results to connect with the verifier node cluster. Transaction requests include three types: issue transactions, quote transactions, and ask transactions. A publication transaction is a participant initiating a transaction for uploading assets (pictures, videos, files). A quote transaction is an operation of authorization, access, download, etc. to an asset whose action may alter an account liveness score. The inquiry transaction is a participant asking the verifier node for an additional transaction issuance cost to be paid according to the required uplink requirement, which may be digital currency or a virtual thing approved by other members in the alliance chain network.
The verifier node cluster 2 includes a plurality of verifier nodes, each node stores a copy of a block chain, stores state information of all accounts, and is used for reviewing compliance of requests initiated by participant nodes. Each verifier node in the verifier node cluster 2 is respectively connected with the participant node cluster 1 and the sequencing node cluster 3.
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 a new block is synchronized. When it receives a transaction request from a participant, it reviews its request. If the compliance check and trial execution process is passed, the verifier node sends a request success response result back to the participants, and submits the signed transaction request to the sequencing node cluster, and the transaction request is included in a newly issued block. Otherwise, rejecting and sending the response result back to the participant.
The sequencing node cluster 3 comprises a plurality of sequencing nodes, each of which can be deployed on a server, and is used for providing a global sequencing service for transactions and is responsible for selecting transactions to add to a newly issued block. Each sequencing node is connected with the verifier node cluster 2.
After receiving the transaction sent by the verifier node, the nodes in the sequencing node cluster firstly review the signature of the verifier, judge the transaction type after the review is passed, put the transaction into a maintained transaction pool according to time sequence when the transaction type is not a price inquiry type, run TCE to provide global sequencing service for the transaction in the transaction pool according to a preset rule when a new block is to be issued, and arrange the sequenced transaction into a network after M transactions before being selected are arranged and selected according to the block. And when the transaction type is the price inquiry type, the TCE is operated to obtain the predicted 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, a node may play multiple roles.
In particular, the TCE4 provided in this embodiment may be configured in a sequencing node of a federation chain network, and the main functions are to provide global sequencing services for transactions and to compute the issuance cost of transactions. TCE4 may also be deployed in a separate server in other ways.
The form of the preset rules deployed in the TCE: the activity score of the account, the existence time of the transaction in the transaction pool and the issuing cost of the transaction are obtained through the account address of the initiator of the transaction, the ranking value of the transaction is comprehensively calculated, the global ranking of the transaction in the transaction pool is determined according to the calculated ranking value, and after the first M transactions are determined, the transactions are packaged into blocks and issued to the chain by the ranking node.
The TCE has two main functions, the first is to determine the transaction ordering order according to preset rules, and the second is to return the issuance cost required for the transaction to the participants according to preset rules, which can be digital currency or virtual things approved by other members in the alliance chain network.
Fig. 2 is a flowchart of operations of a participant-based federation chain incentive system according to a second embodiment of the present invention, where the process specifically includes:
step S20, the participant initiates a request;
and step S21, the verifier node receives the request initiated by the participant, performs compliance check and trial execution, and enters step S22 to judge whether the review passes, and if the review passes, the verifier node performs step S23 to send the transaction request to the sequencing node. Otherwise, step S24 is performed to return error information to the participant node, and the error request is discarded;
step S25 checks whether the signature of the verifier is correct, if the check is passed, step S26 determines whether the transaction type is a price inquiry type, and if not, step S28 is performed, and the node is placed in the transaction pool according to the time sequence of the transaction arrival. When a new block is to be issued, the TCE is operated, the first M transactions are selected according to the operation result of the device and then packaged into a block for issuing, otherwise, when the transaction type is an inquiry transaction, the step S29 is executed, the sequencing node obtains the issuing cost of the transaction request according to the preset rule of the device and returns the issuing cost to the verifier node which sends the transaction, and the verifier node sends the issuing cost to the participant;
finally, step S210 orders the nodes to broadcast the new blocks into the network, and the nodes in the network update the blocks synchronously.
Fig. 3 is a flowchart of a participant-based federation chain incentive process in a third embodiment of the present invention, where the solution in the third embodiment of the present invention is applicable to a participant node in a federation chain network, and the node may be a lightweight node. The method may be performed by a participant-based federation chain incentive device TCE, which may be integrated in a computer apparatus of the sequencing node. The excitation flow chart specifically includes:
step S30, using the times of the participants in the participant behavior data referring to the assets on other account chains as the index for adjusting the activity scores of the participants;
step S31, when the sequencing node runs TCE to sequence the transaction, determining the packaging sequencing sequence of the transaction in the transaction pool according to the preset rule based on the activity score of the participants, the existence time of the transaction in the transaction pool and the cost of transaction release;
step S32, if the participant is an account with high activity score, the more possible the transaction sequence of the participant is, the faster the participant is linked;
step S33, if the participant is the account with high activity score, the lower the issuing cost of the transaction request is obtained according to the preset rule, or even the participant is free, if the participant is the account with low activity score, the purpose of fast chaining can be achieved with high issuing cost;
and step S34, the goal of motivating the participants to join and release the high-quality asset uplink so as to attract other participants to download references is achieved. The more reliable the resources on the chain, the more active the participants and the more secure the blockchain ecology.
