[0003] Currently, in the blockchain, proposers can propose building blocks and build them. Verifiers verify the blocks built by proposers and broadcast them when the verification is passed. Proposers can outsource the right to build blocks, and each node in the blockchain can compete with each other to obtain the right to build blocks.

[0004] However, since the data stored in each block is different, the value of each block is also different, which in turn leads to different incentives for building each block, thus affecting the stability of the building blocks and reducing the overall stability and security of the blockchain.

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] Blockchain is a distributed ledger that combines data blocks into a specific data structure in a chain manner, which is used to store data. Specifically, the blockchain is composed of a data layer, a network layer, and a consensus layer. Among them, the data layer includes at least one block, and the data layer can store information in the blockchain through each block. The network layer can be a point-to-point network composed of at least one node. Each node in the network layer can be used to create blocks, store the created blocks, and broadcast the created blocks to other nodes in the blockchain, so that each node can store the blocks created by itself and the blocks created by other nodes. In addition, the node can also verify the validity and legitimacy of the information stored in the block, so that the block can be added to the blockchain when the block passes the verification. The consensus layer can encapsulate various consensus algorithms, and through the consensus algorithm, the information stored in each block between each node is consistent, so as to ensure the consistency of data of each node in the blockchain and ensure the security and credibility of the information in the blockchain.

[0048] Currently, the role of each node in the blockchain is different, including verification nodes used to verify the legitimacy of newly created blocks, proposal nodes used to propose the creation of blocks according to customer needs or according to predetermined network rules, and construction nodes used to build blocks.

[0049] Specifically, the proposer, i.e. the proposing node, can propose a building block and build a block as a builder, i.e. as a building node. Then the verifier, i.e. the verifying node, can verify the block built by the builder and broadcast the block to add it to the blockchain when the verification passes. In actual situations, the proposing node can not only propose building blocks as a proposing node, but also build new blocks as a building node.

[0050] In practical applications, building blocks requires a lot of time and resources. In order to reduce their own operating costs and risks, the proposer can distribute the right to build blocks to other nodes in the blockchain, so that other nodes can build blocks without the proposer having to build blocks, and after successful creation.

[0051] At present, for the stability and security of blockchain, more nodes need to be incentivized to participate in the construction of blocks. Nodes can be incentivized by increasing additional storage space, computing resources, network bandwidth or rewarding digital currency, that is, nodes obtain corresponding incentives when they successfully create blocks. However, since the data stored in each block is different, the value of each block is also different, which in turn leads to different incentives for building each block, making more nodes tend to build blocks with high value or high incentives, while blocks with low value or low incentives are difficult to be successfully built, thus affecting the stability of building blocks and reducing the overall stability and security of blockchain.

[0052] Based on this, an embodiment of the present application provides a block construction method, by determining at least one construction credential and determining the construction evaluation value of each construction credential, the construction credential is the credential of the construction block, the number of construction credentials is related to the number of blocks to be constructed in the construction cycle, and the construction evaluation value is related to the value evaluation value of each block in the historical construction cycle, and then according to the disposable value of each builder in the blockchain and the construction evaluation value of the construction credential, each construction credential is assigned to the corresponding builder, and the builder constructs the block to be constructed in the construction time slot corresponding to the construction credential, and the value evaluation value of the block in the historical construction cycle can be used as an incentive for constructing the block, and each builder is assigned a construction credential for constructing the block to be constructed, so that the builder has the same incentive to construct each block, thereby improving the stability of the construction block, as well as improving the overall stability and security of the blockchain.

[0053] See also Figure 1 , Figure 1 A flowchart of a block construction method provided by an embodiment of the present application is shown, which may specifically include the following steps:

[0054] Step 101 : determining at least one build credential and determining a build evaluation value of each build credential.

[0055] The construction voucher may be a voucher for a construction block, the number of construction vouchers may be related to the number of blocks to be constructed in a construction cycle, and the blocks to be constructed may be blocks that need to be constructed in a construction cycle. The construction evaluation value may be related to the value evaluation value of each block in a historical construction cycle, and the value evaluation value of a block may be a value for evaluating the value of data stored in the block. The historical construction cycle may be one of the construction cycles in the past period of time, and the construction cycle may be a cycle for building blocks.

[0056] In a specific implementation, the construction cycle of the construction blocks can be defined, and the number of blocks that need to be created in the construction cycle can be defined. Then, before the start of the current construction cycle, the corresponding number of construction vouchers can be determined based on the pre-defined number of blocks that need to be created, and the value assessment values ​​of all blocks in one of the construction cycles in the past period of time can be obtained. Then, the construction assessment value of each construction voucher can be determined based on the value assessment values ​​of all blocks in one of the construction cycles in the past period of time.

[0057] It needs to be understood that since there are multiple proposers and builders in the blockchain, multiple blocks will be constructed, and each new construction needs to be added to the blockchain after verification. Therefore, each newly constructed block needs to be verified and broadcast, which results in a large workload. In addition, a large number of blocks need to be processed at a certain moment, but no blocks need to be processed at another moment. This leads to uneven distribution of computing resources and network resources, and poor stability of block construction.

[0058] Based on this, a fixed time period can be defined as the time period for building blocks, that is, the construction cycle of building blocks and the number of blocks that need to be created in the fixed time period can be defined. Then, the blocks can be built and verified in sequence within the corresponding construction cycle, and the newly created blocks can be added to the blockchain in batches at fixed time intervals, so that the blockchain can perform operations such as block construction, verification and broadcasting in a periodic manner, which improves the stability of building blocks in the blockchain and improves the utilization rate of computing resources and network resources.

[0059] In an embodiment of the present application, determining the construction evaluation value of each construction credential in step 101 may include the following steps:

[0060] An average block value of at least one historical construction cycle is determined, and a construction assessment value of each construction voucher is determined based on the average block value and a dynamic coefficient.

[0061] The average block value may be the average of the value assessment values ​​of all blocks in the historical construction cycle, and the dynamic coefficient may be determined based on the proportional relationship between the average block values ​​between any two historical construction cycles.

[0062] In practical applications, the value assessment values ​​of all blocks in one of the construction cycles in the past period of time can be obtained, that is, the value assessment values ​​of each block in at least one historical construction cycle are obtained, and the average value assessment values ​​of all blocks in each historical construction cycle is calculated, that is, the average block value of each historical construction cycle is calculated, and the average value assessment values ​​of all blocks in all historical construction cycles are calculated, that is, the average block value of each block in all historical construction cycles is calculated, and then based on the average block value of each historical construction cycle, the proportional relationship between the average block values ​​between any two historical construction cycles can be calculated, and the dynamic coefficient can be determined based on the proportional relationship, so as to determine the construction assessment value of each construction credential according to the average block value of each block in all historical construction cycles and the dynamic coefficient.

[0063] Exemplarily, the past period may include historical construction cycle A, which may include block 1 and block 2, the value assessment value of block 1 may be 5, and the value assessment value of block 2 may be 15, then the average block value of historical construction cycle A may be calculated to be 10. Another exemplary example, the past period may include historical construction cycle A and historical construction cycle B, wherein the average block value of historical construction cycle A is 10, and the average block value of historical construction cycle B is 20, and historical construction cycle A may include 2 blocks, and historical construction cycle B may include 3 blocks, then the average value assessment value of all blocks in all historical construction cycles may be calculated to be 16, and the ratio relationship between the average block value of historical construction cycle A and historical construction cycle B may be calculated to be 1:2, and then based on the ratio relationship and the average value assessment value of all blocks in all historical construction cycles, the construction assessment value may be determined to be 8, that is, the construction assessment value of each construction voucher.

[0064] In an embodiment of the present application, determining at least one construction credential in step 101 may include the following steps:

[0065] The number of blocks to be constructed in the current construction cycle is determined, and at least one construction credential is generated based on the number of blocks to be constructed.

[0066] The number of construction vouchers is less than or equal to the number of blocks to be constructed.

[0067] In a specific implementation, since the number of blocks that need to be created in a construction cycle can be pre-defined, the number of blocks that need to be created in the current construction cycle can be determined before the current construction cycle starts, that is, the number of blocks to be built in the current construction cycle is determined, and based on the current construction cycle, at least one construction credential is generated, and each construction credential can correspond to a block to be built, and the number of construction credentials can be less than or equal to the number of blocks to be built.

[0068] Step 102 , allocating each construction voucher to a corresponding builder according to the disposable value of each builder in the blockchain and the construction evaluation value of the construction voucher.

[0069] The disposable value may be the assessed value of the resources used by the builder to build the block.

[0070] After obtaining the construction voucher and its construction evaluation value, the disposable value of each builder can be determined.

[0071] It is important to understand that since the construction of blocks requires a lot of time and resources, in order to increase the success rate of building blocks, it is necessary to determine the resources that can be used by builders to build blocks and calculate the assessed value of the resources used by each builder to build blocks, that is, to calculate the disposable value of each builder.

[0072] After obtaining the disposable value of each builder, each construction voucher can be allocated to the corresponding builder according to the disposable value of each builder in the blockchain and the construction evaluation value of the construction voucher, that is, allocated to the builder who can successfully build the block to be built.

[0073] In actual applications, due to the operating environment, operating algorithm, geographical location and machine configuration of each builder, the resources that can be used to build blocks by each builder are also different. For example, computing power, network bandwidth, storage space, digital currency and other resources are also different. Then, by calculating the disposable value of each builder and matching the disposable value of each builder with the construction evaluation value of the construction voucher, the construction voucher can be assigned to the matching builder, that is, the construction voucher is assigned to the builder whose disposable value is greater than or equal to the construction evaluation value of the construction voucher, thereby increasing the probability of building blocks and improving the stability of building blocks.

[0074] In the specific implementation, since the successful construction of a block will reward the builder with corresponding resources, it will encourage more builders to build blocks and improve the stability of the blockchain. In turn, each builder will be incentivized to build blocks and compete for each construction credential in the hope of being allocated a construction credential and building a block based on the construction credential.

[0075] Specifically, for each build voucher, at least one builder currently competing for the build voucher can be determined, and the disposable value of each builder for building blocks can be determined, so that the builder with the highest disposable value that is greater than or equal to the build assessment value of the build voucher can be determined from each builder, and the build voucher can be allocated to the builder.

[0076] In one embodiment of the present application, the disposable value of each builder can be represented by digital currency, that is, the builder can obtain the corresponding digital currency by renting computing power, storage space or network bandwidth, and then the disposable value of each builder can be represented by digital currency, wherein the digital currency can be a currency in digital form issued based on blockchain technology, such as digital RMB, digital US dollar and other legal currencies, and this application does not impose any restrictions here.

[0077] See also Figure 2 , Figure 2 A schematic diagram of a competitive construction credential provided by an embodiment of the present application is shown. Figure 2 As shown, construction voucher 1 can be competed by 3 builders, and the construction evaluation value of construction voucher 1 is 101. Among them, the disposable value of builder A is 100 digital currencies, the disposable value of builder B is 101 digital currencies, and the disposable value of builder C is 103 digital currencies. It can be determined that builder C is the builder with the highest disposable value among all builders and greater than or equal to the construction evaluation value of the construction voucher, and construction voucher 1 is allocated to builder C.

[0078] Step 103 : The builder builds the block to be built in the building time slot corresponding to the building credential.

[0079] The construction time slot may be a specific time for constructing the block to be constructed. The construction cycle may include at least one construction time slot, and each construction time slot may correspond to one of the blocks to be constructed.

[0080] After each build credential is assigned to the corresponding builder, each builder can determine the build slot corresponding to the build credential, that is, determine the specific time in the current build cycle when the builder is allowed to build the block, and then when the current time is the build slot corresponding to the build credential, the corresponding builder builds the block to be built.

[0081] In one embodiment of the present application, each builder can compete for a construction credential based on disposable value, and when successfully competing for the construction credential, pay the disposable value proposed by the builder during the competition. The blockchain can then obtain and store the disposable value paid by the builder when competing for each construction credential, and after the construction cycle ends, the disposable value obtained in the construction cycle can be evenly distributed to all proposers who proposed blocks in the construction cycle.

[0082] Exemplarily, a construction cycle may include two blocks to be constructed, namely, block A and block B, and then a corresponding number of construction vouchers may be generated based on the number of blocks to be constructed in the construction cycle, that is, two construction vouchers are generated, wherein construction voucher a may be a construction voucher corresponding to block A, and construction voucher b may be a construction voucher corresponding to block B. Builder A in the blockchain may propose to pay 10 digital currencies to compete for construction voucher a, and pay 10 digital currencies when successfully competing for construction voucher a, while builder B in the blockchain may propose to pay 20 digital currencies to compete for construction voucher b, and pay 20 digital currencies when successfully competing for construction voucher b, and then the disposable value of 30 digital currencies obtained in the construction cycle may be evenly distributed to all proposers who proposed blocks in the construction cycle.

[0083] It should be understood that since the data stored in each block is different, the value of each block is also different, and each proposer can distribute the block he proposed to other nodes for construction and obtain corresponding digital currency benefits. The benefits that can be obtained from blocks with lower values ​​are also relatively low, which will lead to the proposer's incentive to propose blocks with lower values ​​being lower than the incentive to propose blocks with higher values, thereby reducing the stability of the proposer's proposed blocks, as well as the overall stability and security of the blockchain. Based on this, by evenly distributing the disposable value obtained in each construction cycle to all proposers who proposed blocks in the construction cycle, it can ensure that the proposer's incentives for proposing each block are basically the same, reducing the situation where the incentives for proposing blocks with lower values ​​are lower than the incentives for proposing blocks with higher values, thereby improving the stability of the proposer's proposed blocks, as well as the overall stability and security of the blockchain.

[0084] See also Figure 3 , Figure 3 A schematic diagram of distributing disposable value provided by an embodiment of the present application is shown as follows: Figure 3 As shown, Figure 3 It shows that 32 blocks to be built need to be built in one construction cycle, and each block to be built can correspond to one construction time slot, that is, the construction cycle includes 32 construction time slots, and each block to be built is proposed by 32 proposers, and then a construction voucher corresponding to the number of blocks to be built can be generated, that is, 32 construction vouchers are generated. For the 32 construction time slots, builder A competes for 12 construction vouchers with an average of 51 digital currencies, builder B competes for 10 construction vouchers with an average of 50 digital currencies, and builder C competes for 10 construction vouchers with an average of 52 digital currencies. Based on this, the digital currency obtained in the construction cycle can be evenly distributed to each proposer, that is, each proposer obtains 51 digital currencies.

[0085] In an embodiment of the present application, the following steps may also be included:

[0086] The builder broadcasts the construction certificate to the proposer corresponding to the block to be built, so that the block to be built can be added to the blockchain.

[0087] Among them, the proposer can be used to broadcast the construction credentials to each verifier in the blockchain, and the verifier can be used to verify whether the builder of the block to be built has the corresponding construction credentials, and to add the block to be built to the blockchain when the builder of the block to be built holds the corresponding construction credentials.

[0088] After the builder constructs the block to be constructed, the builder can broadcast the construction credential to the proposer corresponding to the block to be constructed, and broadcast the constructed block to be constructed to the corresponding proposer, that is, broadcast to the proposer who proposed the block to be constructed, and then the proposer can broadcast the received construction credential and the block to be constructed to each verifier in the blockchain, and each verifier can verify the legitimacy of the currently constructed block to be constructed, and verify whether the builder who constructed the block to be constructed has the corresponding construction credential, so that the block to be constructed can be added to the blockchain if the builder of the block to be constructed holds the corresponding construction credential and the currently constructed block to be constructed passes the legitimacy verification.

[0089] In an embodiment of the present application, by determining at least one construction credential and determining the construction evaluation value of each construction credential, the construction credential is the credential of the construction block, the number of construction credentials is related to the number of blocks to be constructed in the construction cycle, and the construction evaluation value is related to the value evaluation value of each block in the historical construction cycle, and then according to the disposable value of each builder in the blockchain and the construction evaluation value of the construction credential, each construction credential is allocated to the corresponding builder, and the builder constructs the block to be constructed in the construction time slot corresponding to the construction credential. The value evaluation value of the block in the historical construction cycle can be used as an incentive for constructing the block, and each builder is allocated a construction credential for constructing the block to be constructed, so that the builder has the same incentive to construct each block, thereby improving the stability of the construction block, as well as the overall stability and security of the blockchain.

[0090] See also Figure 4 , Figure 4 A flowchart of another block construction method provided by an embodiment of the present application is shown, which may specifically include the following steps:

[0091] Step 401 : determining at least one build credential and determining a build evaluation value of each build credential.

[0092] For the relevant description of step 401, please refer to step 101 and will not be repeated here.

[0093] Step 402, determining the disposable value of each builder for the construction voucher in the blockchain.

[0094] Among them, the builder has different disposable values ​​corresponding to different construction credentials.

[0095] In practical applications, for each build voucher, the resources that each builder can control for the build voucher can be calculated, that is, the disposable value of each builder for the build voucher can be determined.

[0096] It is necessary to understand that different builders will have different disposable values, and the same builder will have different disposable values ​​at different times. For example, after a builder is assigned a construction voucher at a previous moment, his disposable value will decrease, and thus the disposable value of the builder at the current moment is less than the disposable value at the previous moment.

[0097] In a specific implementation, the disposable value of each builder for each build voucher can be determined in sequence. For example, for the first build voucher, the disposable value of each builder for the first build voucher can be determined, and after the first build voucher is allocated to the corresponding builder, the disposable value of each builder for the second build voucher can be determined, and so on, the disposable value of each builder for the build voucher can be determined.

[0098] Specifically, for each construction credential, the resources used by the builder to build blocks at the current moment can be evaluated, that is, the computing power, storage space, network bandwidth, digital currency and other resources used by the builder to build blocks can be evaluated to obtain the disposable value of each builder at the current moment.

[0099] Step 403 , according to the disposable value of each builder and the construction evaluation value of the construction voucher, a target builder is selected from all builders, and the construction voucher is allocated to the target builder.

[0100] The target builder may be the builder with the highest disposable value among all builders.

[0101] After obtaining the disposable value of each builder for the build voucher, the builder with the highest disposable value that is greater than or equal to the build evaluation value of the build voucher can be determined from each builder as the target builder, and the build voucher can be assigned to the target builder, and then each build voucher can be assigned to the corresponding builder.

[0102] Step 404 : The target builder builds the block to be built in the building time slot corresponding to the building credential.

[0103] After each build credential is assigned to the corresponding target builder, the build time slot corresponding to each build credential can be determined, and then the build time slot matching the current moment can be determined, as well as the build credential corresponding to the current moment can be determined, and then the target builder assigned the build credential can build the block to be built at the current moment.

[0104] In an embodiment of the present application, before step 404, the following steps may also be included:

[0105] Assign an arbitrary build time slot to each build credential.

[0106] The construction time slot may be a time period during which each block to be constructed is constructed in a construction cycle, and different blocks to be constructed correspond to different construction time slots.

[0107] After each build voucher is assigned to a corresponding builder, any build time slot can be assigned to each build voucher, and different build vouchers correspond to different build time slots, that is, different build vouchers correspond to different blocks to be built.

[0108] Exemplarily, the number of blocks that need to be created in the construction cycle can be defined as 3, and each block is constructed in different time slots of the same construction cycle, that is, the construction cycle can include construction time slots of 3 blocks, and different blocks can correspond to different construction time slots. After determining the number of blocks that need to be created in the construction cycle, the corresponding number of construction vouchers can be determined based on the number of blocks that need to be created, that is, 3 construction vouchers can be generated, and then each construction voucher can be assigned to the corresponding builder based on the disposable value of each builder in the blockchain and the construction evaluation value of the construction voucher, that is, the generated 3 construction vouchers are respectively assigned to the corresponding builders. For example, the first construction voucher can be assigned to builder A in the blockchain, the second construction voucher can be assigned to the second builder B, and so on, and then each construction voucher can be assigned to the corresponding builder. After each construction voucher is assigned to the corresponding builder, any construction time slot can be assigned to each construction voucher, such as assigning construction time slot 1 in the construction cycle to the first construction voucher, assigning construction time slot 2 in the construction cycle to the second construction voucher, and so on.

[0109] After each build credential is assigned to any build time slot, the build time slot corresponding to the current moment can be determined, and the build credential corresponding to the current build time slot can be determined, that is, the block to be built for block construction in the current build time slot can be determined, and the build credential representing the construction of the block to be built can be determined, as well as the builder holding the build credential, so that the block to be built can be built by the builder.

[0110] In an embodiment of the present application, step 404 may include steps 4041 to 4042:

[0111] Step 4041, determine a target construction time slot that matches the current time slot.

[0112] The target construction time slot may be a construction time slot in the construction cycle that matches the current time.

[0113] After each build voucher is assigned to any build time slot and each build voucher is assigned to a corresponding builder, a target build time slot corresponding to the current time may be determined.

[0114] For example, the current build cycle may be a time period with a start time of 9:00 and an end time of 9:10, and the current build cycle may include 5 build time slots, i.e., each build time slot is 2 minutes long, the first build time slot may be a time period from 9:00:01 to 9:02:00, the second build time slot may be a time period from 9:02:01 to 9:04:00, and so on. When the current time is 9:02:01, the build time slot that matches the current time may be determined to be the second build time slot, i.e., the build time slot at the current time is determined to be the target build time slot.

[0115] Step 4042: When the construction voucher corresponding to the target construction time slot is allocated to the target builder, the target builder constructs the block to be constructed in the target construction time slot.

[0116] After determining the target build time slot, it may be determined whether the build credential corresponding to the target build time slot has been allocated to a corresponding builder.

[0117] It should be understood that since the disposable value of each builder is different at each moment, there will be a situation where the disposable value of each builder is less than the construction evaluation value of the construction voucher at a certain moment, and the construction voucher will not be allocated to any builder in the blockchain. Therefore, it is necessary to determine whether the construction voucher corresponding to the target construction time slot has been allocated to the corresponding builder.

[0118] When the build credentials corresponding to the target build slot are allocated to the corresponding builder, that is, when the build credentials corresponding to the target build slot are allocated to the target builder, the target builder can build the block to be built in the target build slot.

[0119] In an embodiment of the present application, the following steps may also be included:

[0120] When the construction voucher corresponding to the target construction slot is not assigned to any builder, the target proposer builds the block to be built in the target construction slot.

[0121] The target proposer may be a proposer who proposes the target block among all proposers, and the target block may be a block to be constructed in a target construction time slot among all blocks to be constructed.

[0122] When the construction voucher corresponding to the target construction slot is not assigned to any builder, there is no corresponding builder to build the block to be built corresponding to the target construction slot, and the target proposer who proposes the block to be built needs to build it, that is, the target proposer builds the block to be built in the target construction slot.

[0123] In one embodiment of the present application, the blockchain may also store the digital currency income of the target proposer for constructing the block to be constructed, and evenly distribute the disposable value obtained in the construction cycle and the digital currency income of the target proposer for constructing the block to be constructed to all proposers who proposed the block in the construction cycle.

[0124] It is important to understand that since successful block construction can obtain corresponding incentives, that is, digital currency of corresponding value, the proceeds from block construction need to be evenly distributed to other proposers to further ensure that the incentives for proposers to propose each block are basically the same, reducing the situation where the incentives for proposing blocks with lower values ​​are lower than those for proposing blocks with higher values, thereby further improving the stability of proposers proposing blocks and improving the overall stability and security of the blockchain.

[0125] In an embodiment of the present application, by determining at least one construction credential and determining a construction evaluation value of each construction credential, the construction credential is a credential for a construction block, the number of construction credentials is related to the number of blocks to be constructed in a construction cycle, and the construction evaluation value is related to the value evaluation value of each block in a historical construction cycle, thereby determining the disposable value of each builder in the blockchain for the construction credential, and selecting a target builder from all builders based on the disposable value of each builder and the construction evaluation value of the construction credential to assign the construction credential to the target builder, and the builder constructs the block to be constructed in the construction time slot corresponding to the construction credential, so that the value evaluation value of the block in the historical construction cycle can be used as an incentive for constructing the block, and each builder is assigned a construction credential for constructing the block to be constructed, so that the builder has the same incentive to construct each block, thereby improving the stability of the construction block, as well as improving the overall stability and security of the blockchain.
