Description

Blockchain consensus method and blockchain network for realizing marketing label sharing

technical field

The invention belongs to the technical field of block chains, and more specifically relates to a block chain consensus method and a block chain network for realizing marketing label sharing.

Background technique

In the e-commerce (Electronic Business) industry, marketing tags are a summary of customer characteristics or preferences. E-commerce platforms or merchants can use marketing tags to more accurately locate their users and carry out precise marketing based on marketing tags. However, the data held by e-commerce platforms or merchants is relatively independent, and it is difficult to share marketing labels among merchants. Blockchain (Blockchain) has the advantages of decentralization, transparent transaction process, traceability, and easy auditing, which makes e-commerce gradually transfer from a centralized platform to a decentralized blockchain platform.

The consensus mechanism in the blockchain is the key technology to achieve decentralization. Currently, mainstream blockchain consensus mechanisms include Proof of Work (POW for short), Proof of Stake (POS for short) and Delegated Proof of Stake (DPOS for short). The principle of POW is to require each node to calculate a random number with a certain degree of difficulty, so a lot of computing resources will be wasted; The more nodes are more likely to become a block node, which will lead to the problem of centralization; the principle of DPOS is to vote for a certain number of representative nodes through the nodes holding rights and interests, and these representative nodes form a committee, and the committee The representative nodes in DPOS take turns to generate blocks. Compared with the other two mechanisms, DPOS can better avoid the problem of wasting computing resources while improving performance.

However, DPOS has the following three problems: (1) In the blockchain network, the nodes holding the rights and interests determine the representative nodes with the right to produce blocks, and the rights and interests in it have no connection with the shared marketing tags, so it is impossible to motivate e-commerce platforms or Merchants share marketing labels, so it is difficult to directly combine traditional DPOS with e-commerce; (2) DPOS is not flexible enough. , the block producing node still needs to continuously determine the block producing node in the next committee while producing the block, which will increase the burden on the blockchain network; (3) After DPOS determines the block producing node in the next committee, it will The list of block producers of the next committee is sent through network-wide broadcast, and in the case of the above-mentioned block chain network emergency, due to the delay in the block chain network, the newly selected block block nodes may not be able to obtain relevant information in time. Information, and timely participation in block generation, which will lead to a delay in block generation time, further increasing the burden on the blockchain network.

The present invention provides a block chain consensus method and a block chain network for realizing marketing label sharing. The shared points in the chain network determine the block-generating nodes with block-generating rights, thereby incentivizing e-commerce platforms or merchants to share marketing labels; secondly, by increasing the current block-generating node set (current committee) Validity period, and after confirming the next block producing node set (the next committee), the current committee is only responsible for producing blocks, thus reducing the system overhead of the blockchain network to deal with emergencies; finally, through the sudden increase in the number of transactions When there is an emergency, the effective time of the next committee will be postponed backwards, which solves the block delay problem caused by the delay of the blockchain network in the event of an emergency, and further reduces the block chain network in the event of an emergency. burden.

Among them, the shared points of nodes change through the transaction of marketing tags, and the larger the transaction volume of marketing tags, the larger the increment of shared points; the time length of each stage is equal, and the validity period of the block producing node set includes one or more stages; MAX is The preset threshold for the number of block producers.

In an optional implementation, in the above blockchain consensus method for sharing marketing tags, sharing points can be obtained by selling marketing tags, and can also be purchased with currency, while in order to obtain marketing tags, only through Share point purchases.

In an optional implementation manner, the above-mentioned block chain consensus method for realizing marketing label sharing also includes:

In the stage p _i , all the block producing nodes in the block producing node set S _i and some other nodes in the blockchain network send registration transactions to the blockchain network as registration nodes, and apply to become the next block producing node set S _i Block producers in ₊₁ ;

In actual situations, nodes other than the current block producing node S _i can decide whether to send registration transactions as registration nodes according to their shared integral variables in the corresponding period.

In an optional implementation, the last block producing node N _i of the block producing node set S _i determines the effective stage of the block producing node set S _i+1 according to the current system pressure, including:

It should be understood that the delay factor can also be other quantities that can represent the current system pressure, and will not be listed here;

The effective period of the current block generation node set is appropriately extended; the effective interval E can be determined according to the transaction characteristics of the blockchain network and the block generation capabilities of the nodes, so as to ensure that in the case of an emergency in the blockchain network, through appropriate Extending the valid period of the current block producing node set and postponing the effective time of the next block producing node set can effectively relieve the pressure on the system.

In an optional embodiment, after the validity period of the current block node set and the effective stage of the next block node set are determined by the above method, the block chain consensus method for realizing marketing label sharing provided by the present invention ,Also includes:

If f _i > M, it means that the current system pressure is high, then in the first to E stages after the stage p _i , that is, after the next block producer node set S _i+1 is determined, until the block producer node set S _i+1 Before it takes effect, the block producing nodes in the block producing node set S _i take turns to produce blocks to process system transactions, and no longer process registration transactions while producing blocks; when the effective stage of block producing node set S _i+1 arrives, the producing The block node set S _i+1 takes effect to produce blocks from the block producing nodes, and the validity period of the block producing node set S _i ends;

Otherwise, it means that the current system pressure is relatively normal. When the effective stage of the block producing node set S _i+1 is reached, the block producing node set S _i+1 takes effect to produce blocks from the block producing nodes, and the block producing node set S the validity period of _i ends;

It should be understood that as the transactions in the blockchain network continue to proceed, at different stages, the current set of block-producing nodes is different. After the next block-producing node set S _i+1 takes effect, the block-producing node set S _i+1 will become the new current set of block producers.

In an optional implementation, the last block producing node N _{i of the block producing node set S i determines} up to MAX registered nodes as the block producing nodes of the next block producing node set S _i+1 , including:

The block producing node N _i sorts the registration nodes according to the order of decreasing increment of shared points;

If the number of registered nodes C _i satisfies C _i ≤ MAX, then according to the sorting results, each registered node is sequentially determined to be the next block producing node set S _i+1 ; otherwise, according to the sorting results, the shared point increment is determined sequentially The largest first MAX nodes are the block producing nodes of the next block producing node set S _i+1 ;

The threshold MAX of the number of block-producing nodes can be determined according to the scale of the blockchain network and transaction characteristics.

In an optional implementation, the block producing nodes in the block producing node set produce blocks in turn, including:

(S1) The current block producing node produces blocks to process system transactions and obtain rewards until the number of consecutive blocks produced by the block producing node reaches the preset block number threshold B, or the block producing time of the block producing node reaches the preset The threshold T of the block generation time; the rewards obtained by block generation nodes include shared points, and can also include electronic currency, etc.;

(S2) If the block producing node is not the last block producing node in the set of block producing nodes, go to step (S1) to produce a block by the next block producing node; otherwise, the block producing ends.

The block production module is used to produce blocks to process system transactions when the node belongs to the current block production node set S _i and it is the turn of the node to produce blocks at the initial stage p _i of the block production node set S _i validity period;

The registration transaction processing module is used to receive the registration transaction sent by the registration node in the blockchain network at the same time as the block generation module generates the block, and when receiving the registration transaction, calculate the last one in the previous block generation node set S _i-1 The share point increment of the corresponding registration node between the time when the block generation node ends and the time when the registration transaction is sent is recorded in the registration transaction, and the registration transaction is written into the block;

In the blockchain network for sharing marketing tags provided by the present invention, the specific implementation of each module of the node can refer to the description in the above method embodiment, and will not be repeated here.

Applications:

Initialize each preset parameter and write it into the configuration file, specifically including: the effective interval of the next block producing node set (next membership meeting) in case of an emergency is E=3, the threshold for the number of block producing nodes is MAX=2, The threshold of the number of blocks produced by a single node for continuous block production is B=10, the threshold for the block production time of a single node for continuous block production is T=10s, and the delay factor is influx at the beginning of the validity period of the current block production node set (current committee) The transaction volume of the blockchain network, the corresponding system pressure threshold is M=500;

As shown in Figure 2, the specific process of the blockchain consensus method for realizing marketing label sharing is as follows:

In the X-1 stage, the members of the committee take turns to produce blocks according to the decreasing order of the shared integral increment. The goal of each block producing node is to produce 10 blocks in a row; 10 blocks, then the next node will produce the block after the number of blocks reaches 10, otherwise, when the block production time of the node reaches 10s, the next node will directly produce the block; repeat this process until all nodes in the committee produce blocks complete. At the same time, during the block generation process, ordinary nodes with addresses 0x0001, 0x0002, and 0x0003 in the blockchain network are used as registration nodes to send registration transactions. The current committee node calculates that the shared points increments of these three registration nodes are 50, 40, and 30 respectively. , after recording the increment of shared points in the corresponding registration transaction, write the registration transaction into the block; the last block producing node determines the next committee member according to the increment of shared points (committee members will get rewards of shared points for producing blocks); There are two block producing nodes in the current committee, and their share points increments are 10 and 5 respectively, so there are five registered nodes (common nodes with addresses 0x0001, 0x0002, 0x0003 and two nodes of the current committee), exceeding the The threshold of the number of block nodes is MAX=2, and the top 2 nodes with the increment of shared points are taken as the block producing nodes of the next committee Y, that is, the registration nodes with addresses 0x0001 and 0x0002 are the block producing nodes of committee Y; After Y’s block generation node, since the number of blockchain transactions in the X-1 stage has not reached 500, the delay factor calculated by the last block generation node is less than the system pressure threshold M, therefore, the validity period of the current membership is determined to be 1 stage, and the effective stage of committee Y is stage X; therefore, after the end of stage X-1, in stage X, committee Y will take effect and start to generate blocks, accept registration transactions, and produce the next committee Z.

In the X stage, the block producing nodes in the committee Y take turns to produce blocks in the order of decreasing share credit increment, and the goal of each block producing node is to produce 10 blocks in a row. If the node can generate 10 blocks within the block generation time threshold of T=10s, then the next node will generate the block after the number of blocks reaches 10, otherwise it will be directly handed over to the next node when the node’s block generation time reaches 10s Produce a block; repeat this process until all nodes in the committee produce blocks. At the same time, in the process of block generation, if no registration transaction sent by ordinary nodes is received, the last block generation node of committee Y will still determine the block generation node of the next committee Z according to the increment of shared points (committee members will get shared Integral rewards); there are two block producing nodes in committee Y, that is, nodes with addresses 0x0001 and 0x0002, and the increments of shared points are 10 and 5 respectively, so there are only 2 registration nodes (two nodes in committee Y), no more than The threshold of the number of block nodes is MAX=2, and all registered nodes are taken as the block nodes of the next committee Z, that is, the nodes with addresses 0x0001 and 0x0002 are the block nodes of committee Z. After the block generation node of committee Z is determined, since the number of blockchain network transactions exceeds 500 in the X stage, the delay factor calculated by the last block generation node of member association Z is greater than the system pressure threshold M, therefore, the committee is determined The validity period of Y is E+1=4 stages, and the effective stage of committee Z is the 4th stage after the Xth stage, that is, the X+4th stage; in the 3 stages after the Xth stage, the committee The block producing nodes in Y continue to produce blocks, but they are not processing registration transactions until the X+4th stage is reached, committee Z takes effect, and the block producing nodes in committee Z produce blocks.

In the X+4th stage, committee Z takes effect and starts producing blocks, accepts registration transactions, and produces the next committee W.

Those skilled in the art can easily understand that the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention, All should be included within the protection scope of the present invention.
