Description

block chain transfer method and consensus realization method, device, equipment and medium

Technical Field

the application relates to the technical field of computers, in particular to a block chain technology, and particularly relates to a block chain transfer method, a block chain consensus realization method, a block chain transfer device, a block chain consensus realization device and a block chain consensus realization medium.

Background

The blockchain system is used as a decentralized network node system, and the consistency of operation needs to be realized through a consensus mechanism.

the PoS (Proof of authority) is a consensus mechanism, which is a block chain consensus mechanism that does not depend on energy consumption and achieves on-chain consensus through Proof of authority. PoS agrees on the age of the similar currency, and determines the amount of interest a user has by the amount of virtual currency in the blockchain. The delegation rights and interests certification (DPoS) is a consensus mechanism that a user jointly selects some super nodes for block-out by exchanging virtual currency into votes, and the root of the mechanism is also dependent on the number of the virtual currency.

however, users with a small coin-holding capacity in the PoS mode have little right to participate in the consensus process of determining the block nodes. While all the users of the banknotes can participate in the consensus process of determining the block nodes, the DPoS method may have the problem of bribing.

Detailed Description

the following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

First embodiment

Fig. 1 is a flowchart of a method for transferring a blockchain according to a first embodiment of the present disclosure, where the present embodiment is suitable for processing a transfer transaction request in a blockchain network, and is particularly suitable for processing a transfer transaction request when money to be transferred in the transfer transaction request is rental money. The method may be performed by a block link point, which may be a block exit node in the block link network, or may be another node in the block link network, such as any node that does not currently have block generation permission. The method may be performed by a blockchain transfer device, which may be implemented in software and/or hardware. As shown in fig. 1, the method for transferring block chains according to this embodiment may include:

S101, a currency lease transaction request is received.

the money lease transaction request may be a transaction request requesting that a preset amount of lease money for a leased account be leased to a leased account. The money lease transaction request can be initiated after any one of two leasing parties completes money lease transaction negotiation with the other party; or initiated by a third party delegated by the two leasing parties after the two leasing parties complete the money lease transaction negotiation. Alternatively, the initiating node of the money lease transaction request may be a full node or a lightweight node of the blockchain network.

Optionally, the money lease transaction request of this embodiment may be an intelligent contract or an unspent transaction output UTXO, and when the money lease transaction request is an intelligent contract, the initiating node may obtain the money lease intelligent contract after completing the money lease transaction negotiation, use the money lease transaction as input data, and invoke the virtual machine to run a relevant program code in the money lease intelligent contract regarding generation of the money lease transaction request, so as to obtain the money lease transaction request corresponding to the money lease transaction.

Optionally, when the money lease transaction request is an unspent transaction output UTXO, the transfer-in account field of the UTXO of the present application records a lease account, a transaction data identifier of the UTXO, and the lease account. It should be noted that the UTXO is a field-based data record, and in general, the UTXO includes at least three fields, and one field records a money transfer account; another field records the transfer of money to the account; there is also a field to record currency data such as time, amount, etc. of money transferred. In this embodiment, a field record manner of a general UTXO may be modified for the money lease transaction request, and a transfer account field of the UTXO is recorded with not only a lease account representing a transfer account but also a transaction data identifier (txid) of the UTXO. The transaction data identifier is a unique data identifier for distinguishing each UTXO. The initiating node of the money lease transaction request may generate a money lease transaction request in a field form according to a recording manner of each field of the UTXO based on the money lease transaction after the money lease transaction negotiation is completed. For example, if the money lease transaction is that a leases B10 lease money, the generated money lease transaction request may be represented as, based on the record mode of each field of the UTXO, where the field of the roll-out account is the lease account a; the fields transferred to the account are: rent account B, txid1, rent out account a; the currency data fields are: 10 rental currencies. When the initiating node generates a currency lease transaction request, the generated currency lease transaction request is sent to the block chain network, and the block chain node receives the currency lease transaction request.

s102, executing the money lease transaction request to form money lease transaction data and recording the money lease transaction data into the block.

Optionally, after receiving the money lease transaction request, the block link node processes the lease transaction request to obtain money lease transaction data, where the money lease transaction data at least includes a lease account, lease money, and a lease account. The rental money may include the rental money amount, the rental time, and the like. For example, if the money lease transaction request is that A leases B10 lease money, then after processing the money lease transaction request, the resulting money lease transaction request includes at least: rent account B, 10 lease currencies, rent out account a. Optionally, the money lease transaction request may also be included in the money lease transaction data.

Specifically, when executing the money lease transaction request, if the money lease transaction request is an intelligent contract, the block link points may obtain the money lease intelligent contract, and use the money lease transaction request as input data, and invoke the virtual machine to run the relevant program code related to processing the money lease transaction request in the money lease intelligent contract, so as to obtain the transaction data of the money lease transaction request. If the money lease transaction request is UTXO, then the data recorded in each field in the money lease transaction request may be obtained as the money lease transaction data. Optionally, in this embodiment, while the money lease transaction data is recorded in the current block, the money lease transaction data is also recorded in the local disk, so that the advantage of avoiding traversing the block every time when subsequently searching for the money lease transaction data is achieved is that the efficiency of subsequently searching for the money lease transaction data is improved.

Optionally, the money lease transaction manner in this embodiment is performed based on the online lease transaction request, and is recorded in the blockchain, so that the reliability and traceability of the money lease transaction are improved, and the bribing problem caused by the online operation is avoided.

S103, receiving the transfer transaction request, and if the money to be transferred in the transfer transaction request is the leasing money recorded in the block chain and the transferred account is not a leased account, invalidating the transfer transaction request.

The transfer transaction request may be an existing normal transfer transaction request, i.e., a transaction request requesting a preset amount of money transferred from an account to be transferred to an account. May be initiated by either of the parties or by a third party delegated by the parties. The initiator may be a full node or a lightweight node of the blockchain network. The transfer transaction request of the embodiment may also be a smart contract or non-spending transaction output UTXO, and when the transfer transaction request is the UTXO, only the transfer account is recorded in the transfer account field of the UTXO. It should be noted that, similar to the money lease transaction request in this embodiment, the transfer transaction request requests money transfer from one party to another party, but the difference is that the money transferred to the transfer account based on the transfer transaction request can be paid by the transfer user at will, i.e. a transfer or other transaction can be performed, while the money transferred to the transfer user based on the money lease transaction request is limited in the usage right, e.g. limited to calculating the right value of the account when competing for a block node, and cannot be used for the money transfer, i.e. a transfer or other transaction. The purpose of setting the use permission of the rental money in the embodiment is to prevent the situation that the rental money is immediately transferred out after a malicious node attacks the consensus mechanism by frequently increasing the interest value of the rental money.

optionally, after a transfer transaction request is generated by a generation node of the transfer transaction request, the transfer transaction request is sent to the blockchain network, and a node in the blockchain network receives the transfer transaction request. However, because a money lease transaction exists in this embodiment, and lease money acquired by a lease account in the money lease transaction process does not have transfer use authority, after receiving the transfer transaction request, a block chain node in this embodiment does not directly process the received transfer transaction request, but first determines whether money to be transferred (i.e., money to be transferred) of an export account in the transfer transaction request is money acquired by the lease transaction (i.e., whether the money to be transferred) or not, if so, further determines whether a lease account corresponding to the lease money is an export account of the transfer transaction request, and if not, because the lease account has no export authority for the lease money, the transfer transaction request received this time is invalid, and the transfer transaction request is not executed; otherwise, the received transfer transaction request is valid, the transfer transaction request is executed, and the obtained transfer transaction data is recorded in the blockchain, optionally, the transfer transaction data is also stored in the local disk while being recorded in the blockchain.

Optionally, in this embodiment, when determining whether the money to be transferred in the transfer transaction request is the rental money recorded in the blockchain and determining whether the transfer account is the rental account, the determination may be performed based on an intelligent contract, for example, which money is the rental money and which account is the rental account may be predefined in the intelligent contract, and at this time, the determination may be performed whether the money to be transferred is the rental money recorded in the blockchain and whether the transfer account is the rental account through the predefined intelligent contract. Optionally, because the money lease transaction request and the transfer transaction request of the embodiment may also be UTXO, when determining whether the money to be transferred is lease money, the embodiment may check whether the UTXO corresponding to the money to be transferred further includes a lease account in a corresponding transfer account field, and if yes, indicate that the money to be transferred is lease money; when judging whether the transfer-out account is a rent-out account, the transfer-out account of the transfer transaction request can be obtained from the transfer-out account field of the transfer transaction request, the rent-out account of the rent money can be obtained from the transfer-out account field in the UTXO corresponding to the money to be transferred, and then whether the transfer-out account is consistent with the rent-out account is judged.

According to the technical scheme, the money lease transaction request is received and executed, the lease account, the lease money and the lease account are taken as money lease transaction data to be recorded in the block, and after the transfer transaction request is received, if the money to be transferred is the lease money recorded in the block chain and the transfer account is not the lease account, the transfer transaction request is regarded as invalid. A new money lease transaction mode is provided, under the money lease transaction mode, the use authority of a lease account to the lease money under the name is limited, and the lease money cannot be used for transfer transaction.

Second embodiment

Fig. 2A is a flowchart illustrating a block chain consensus method according to a second embodiment of the present application, and fig. 2B is a graph illustrating a relationship between a currency duration and an equity weight value according to the second embodiment of the present application. The embodiment is suitable for the implementation process of the consensus mechanism of the blockchain network, and is particularly suitable for the implementation process of the POS consensus mechanism of the blockchain network. The method may be performed by a block link point, which may be a block exit node in the block link network, or may be another node in the block link network, such as any node that does not currently have block generation permission. The method may be performed by a block chain consensus implementation apparatus, which may be implemented in software and/or hardware. As shown in fig. 2A-2B, the method for implementing block chain consensus provided in this embodiment may include:

S201, a currency lease transaction request is received.

Optionally, the execution process of S201 may be similar to the execution process of S101 in the first embodiment, and is not described herein again.

s202, executing the currency lease transaction request to record that the lease currency is leased to the lease account by the lease account.

Alternatively, the execution process of S202 may be similar to the execution process of S102 in the first embodiment described above, that is, the process of recording the lease money from the lease account to the lease account in this embodiment is equivalent to the process of forming and recording the money lease transaction data including the lease account, the lease money, and the lease account in the block in S102 in the first embodiment. This is described in detail herein.

And S203, calculating the interest value of the rented account according to the holding currency and the rented currency of the rented account.

the money under the rental account includes two types, one is holding money, and the other is rental money. Holding currency refers to currency acquired by a non-rental transaction under a rental account, the rental account has spending and dominating right on holding currency (such as being used for transferring money), and the holding currency can be used for calculating the right value of an account to which the holding currency belongs; the lease money is money acquired by a lease transaction under a lease account, the lease account has no spending dominance such as transfer account and the like, and for the lease user, the lease money can only be used for calculating the equity value of the account to which the lease money belongs.

Optionally, in this embodiment, the manner of distinguishing whether the money under the rental account is the held money or the rented money may be to distinguish the money by using an intelligent contract, or may distinguish the money by using a UTXO, which has been described in the foregoing first embodiment, and this embodiment is not described in detail herein.

Alternatively, in this embodiment, each block in the block chain may be traversed from back to front in sequence, and the holding currency and the lease currency under the lease account recorded in each block may be searched. If the local disk of the block link point stores the transfer transaction data and the money leasing transaction data, the holding money and the leasing money under the leasing account can be searched from the local disk, and compared with the method for searching the data from the block, the method for searching the data from the local disk has higher efficiency and takes less time. After the holding currency and the rental currency of the rental account are found, there are many ways to calculate the equity value of the rental account according to the holding currency and the rental currency of the rental account, and this embodiment is not limited. The total amount of the held money and the rented money under the rented account can be directly calculated in an accumulation mode, and the accumulated total amount of the money is used as the equity value of the rented account.

in order to prevent a malicious node from frequently transferring or leasing money in a short period of time to improve the equity value of the malicious node, another possible implementation manner of the embodiment in calculating the equity value of a leased account can be realized by the following sub-steps:

s2031, determining a equity weight value according to the holding currency of the rented account and/or the duration of the rented currency in the rented account.

specifically, for the held currency and/or the rented currency under the rented account, the equity weight value of each currency in the various currencies can be determined according to the duration of each currency in the various currencies under the rented account. Wherein, the duration of the money in the account renting can be a time interval from the time when the money is transferred to the account renting to the current time. The equity weight value is increased in proportion to the duration, and the equity weight value does not exceed a set upper limit value. As shown in fig. 2B, the abscissa h represents the duration of the money under the rental account, and the ordinate price represents the equity weight value of the money; when the duration h of the currency under the account renting is less than or equal to the set upper limit N, the corresponding right and interest weight value price is correspondingly increased along with the increase of the duration h; when the duration h of the currency under the account renting condition is longer than the set upper limit N, the corresponding right and interest weight value price is not increased along with the increase of the duration h, and the fixed right and interest weight value 1 is kept unchanged. Optionally, the embodiment may be a unified curve relationship diagram set for the held currency and the rental currency; it is also possible to set different two curve relations for the holding currency and the leasing currency, respectively.

Optionally, when determining the equity weight value of each currency in the leased account according to the duration of the currency in the leased account, the equity weight value may be determined by looking up a table or calculating according to a preset formula, in addition to the above description, and this embodiment is not limited.

S2032, calculating the equity value of the held money and/or the rented money according to the amount of the held money and/or the rented money and the equity weight value.

Specifically, in S2031, the equity weight value of each held currency and/or each rented currency is calculated, and at this time, when the equity value of the held currency and/or the rented currency is calculated, the equity value corresponding to each currency may be obtained by multiplying the number of each held currency and/or each rented currency by the corresponding equity weight value. According to the method, a equity value corresponding to each currency (including holding currency and rental currency) under a rental account is calculated.

S2033, the equity value of the held money and the rented money is accumulated as the equity value of the rented account.

specifically, the calculated equity value of each piece of held money and the equity value of each piece of rented money under the rented account in S2032 are summed, and the summed result is used as the current equity value of the rented account.

It should be noted that, when the equity value of the leased account is calculated, the equity weight value is determined according to the duration of the held currency and the leased currency under the leased account, the equity value of the leased user is calculated in a weighting mode, and the values of the held currency and the leased currency are increased along with time, so that the equity value of a malicious node is prevented from being improved by transferring or leasing a large amount of virtual currency in a short period, and the malicious node holds a large amount of transferred or leased currency for a long period, so that the cost of malicious attack is increased, and the frequent attack of the malicious node on the consensus mechanism is reduced.

and S204, initiating a block-out node competition transaction request based on the interest value according to the interest value of the leased account.

the block-out node competition transaction request may be a transaction request for competing the block node, which is initiated by a node where the node is located when the current equity value of a node user who is not the block-out node reaches the standard for competing for the block node and the node user wants to compete for the block node.

Optionally, a certain number of slots may be preset in the blockchain network for recording the block node, for example, a table may be recorded in the blockchain, where the table includes a set number (e.g., 15) of slots, each slot in the table records an identifier of a block node, and the block nodes perform block outputting according to a preset rule, for example, according to a rule such as rotation, preset time, and the like. When a user of a node wants to compete out a block node, the user selects a node that the user wants to compete out from the block node identifiers recorded in the slots in the table as a target block node (optionally, in order to succeed in competition as much as possible, the user usually selects the block node with the lowest interest value as the target block node). And then obtaining a block competition intelligent contract, using competition data as input data, calling a virtual machine to run a related program code related to generation of a block node competition transaction request in the block competition intelligent contract, and initiating the block node competition transaction request based on the interest value. The competition data may include, but is not limited to, a target block-out node that wants to compete, a rights value of the leased account, and a competition cost (where the competition cost refers to a fixed cost of money, also referred to as a competition cost, regardless of whether the competition is successful). It should be noted that, in addition to initiating the outbound node competition transaction request based on the interest value in a manner based on the intelligent contract, the present embodiment may also initiate in other manners, which is not limited in this embodiment.

optionally, after initiating a block out node competition transaction request based on the equity value, the embodiment may execute a process of the block out node competition transaction request, for example, after all nodes having the equity value receive the block out node competition transaction request, determine whether a lease-in account equity value of a block out node to be contended in the request satisfies a minimum block out election condition (e.g., whether the equity value reaches a preset minimum equity threshold value); and judging whether the interest value of the leased account is larger than the interest value of the target block-out node, judging whether the leased account is a non-block-out node or not, and the like, if so, indicating that the leased account is successful in election, replacing the target block-out node with the leased account, and recording the transaction data of the execution of the competition transaction request in a block chain.

According to the technical scheme of the embodiment of the application, after the currency lease transaction request is received and executed, the equity value of the lease account is calculated according to the money held by the lease account and the lease money, and the block outlet node competition transaction request is initiated based on the equity value. When the rent-out account leases money to the rent-in account, the rent-out account votes for the rent-in account, but because the use authority of the rent-in account to the lease money under the name of the rent-in account is limited in the money lease transaction mode, the lease money cannot be used for transfer transaction, even if a malicious node leases a large amount of lease money from other nodes, the lease money cannot be transferred after the equity value is increased, the cost of malicious attack is high, and further the frequent attack of the malicious node to the consensus mechanism is reduced.

Third embodiment

Fig. 3 is a flowchart of a block chain consensus implementation method according to a third embodiment of the present application, and this embodiment specifically gives a detailed process description how to calculate the equity value of the leased account according to the holding currency and the lease currency of the leased account based on the above embodiments. As shown in fig. 3, the method for implementing block chain consensus provided in this embodiment may include:

s301, a currency lease transaction request is received.

and outputting the UTXO for the non-cost transaction by the currency lease transaction request, wherein a transfer-in account field of the UTXO is recorded with a lease account, a transaction data identifier of the UTXO and the lease account.

S302, executing the money lease transaction request to record that the lease money is leased to the lease account by the lease account.

S303, the blocks of the block chain are divided into a plurality of block sets by using the set number of blocks as a unit.

optionally, in the embodiment of the present application, when the equity value of the rented account is calculated, the equity weight value of each currency of the rented account needs to be calculated, but because the number of times of the currency transaction of the rented account is large, if an equity weight is determined for each currency, the workload is large. Therefore, the present embodiment may divide the blocks in the block chain into at least one block set by taking the set number of blocks as a unit. For example, a block chain network may generate approximately 8 ten thousand blocks a day, 2 ten thousand blocks may be used as a unit of a preset number of blocks, a block set may be divided by every 2 ten thousand blocks of the blocks in the block chain according to the block link order, and a block generated a day may be divided into 4 block sets.

S304, determining a rights weight value of each block set according to the distance between each block set and the current block, wherein the distance corresponds to the duration.

Optionally, the mapping relationship between the distance between the block set and the current block and the equity weight value may be preset in this embodiment, and optionally, the mapping relationship may be represented by a table, a formula, or a graph (as shown in fig. 2B). Then, according to each block set divided in S303, the distance between the block set and the current block is calculated for each block set, and further, a right weight value corresponding to the currently calculated distance is determined as a right weight value corresponding to the block set by presetting a mapping relationship between the distance between the block set and the current block and the right weight value. Since each block in the block chain is linked according to the time sequence, the duration of each currency recorded in the block under the account rented is represented by calculating the distance between each block set and the current block, the transaction time of each currency does not need to be checked, the effect that the value of each currency under the account rented is increased along with the time can be achieved, and the calculation amount for judging the duration of each currency is greatly reduced.

Optionally, in the present embodiment, when calculating the distance between each block set and the current block, the number of blocks separated between the reference block and the current block of each block set may be used as the distance between the block set and the current block. The reference block may be the first block, the last block, or an intermediate block in the block set. For example, if the reference block of the block set is the 10001 th block of the block chain and the current block is the 20001 blocks of the block chain, the distance between the block set and the current block is 10000.

s305, determining the amount of transferred money recorded by each block in each block set, wherein the amount of transferred money comprises the amount of held money and/or the amount of rented money.

where the transfer currency may be currency associated with the transfer transaction, such as may include holding currency obtained through transfer transactions, and rental currency obtained through rental transactions.

Optionally, since the equity value of the rented account needs to be determined based on all transferred-in currencies of the rented account, and each transferred-in currency of the rented account and the transfer transaction request and the currency rental transaction request corresponding to the transferred-in currency are recorded in the blocks of the block chain, the amount value of each transferred-in currency needs to be searched and determined from each block of each block set. Specifically, in this embodiment, the data recorded in each block set may be sequentially traversed, the data of the transfer transaction and/or the data of the lease transaction recorded in the data may be searched, and then the data of the transfer transaction and/or the data of the lease transaction may be analyzed and calculated, so as to determine the amount of held money corresponding to the transfer transaction, and/or determine the amount of lease money corresponding to the lease transaction.

Optionally, the currency lease transaction request of this embodiment outputs UTXO for an unspent transaction, and the transfer-in account field of the UTXO records a lease account, a transaction data identifier of the UTXO, and the lease account. Therefore, when determining the amount of the rental money recorded by each tile in each tile set, the present embodiment can be implemented by the following sub-steps:

s3051, extracting UTXO recorded in each tile of each tile set.

Specifically, the blocks in each block set may be sequentially traversed to check whether data in the form of the UTXO is recorded therein, and if so, the data in the form of the UTXO is acquired. Optionally, the data in the form of the UTXO may have a uniform field identifier, and at this time, it may be determined whether each data in the block record includes the field identifier, and if so, the data is the data in the form of the UTXO. It should be noted that in the present embodiment, the data in the form of UTXO may include money lease transaction data and transfer transaction data in the form of UTXO.

s3052, if the transfer-in account field of the UTXO records the rent account, the transaction data identification of the UTXO and the rent-out account, determining that the transfer-in currency of the UTXO is rent-in currency.

Specifically, the account to be rented, the transaction data identifier of the UTXO, and the account to be rented are recorded in the account to be transferred field in the transaction data of the UTXO of the present embodiment. And the transferred account field in the transfer transaction data in the common UTXO form only records the transferred account. Therefore, the present embodiment may check the transferred account field of the data in the form of UTXO extracted in S3501, and if only the transferred account field has a transferred account, it indicates that the data in the form of TUXO is transfer transaction data, and may determine that the transferred money in the data is held money; if the transfer account field records the transaction data identifier of the renting account, the UTXO and the renting account, the data in the TUXO form is the money renting transaction data, and the transfer money in the data can be determined to be the renting money.

and S3053, calculating the amount of the rented money according to the UTXO.

specifically, the amount value of the rental currency may be acquired from the currency data field of the currency rental transaction data in the form of UTXO.

Alternatively, if the money recorded in the UTXO extracted at S3501 is held money, the amount value of held money may be acquired from the money data field of the transfer transaction data in the form of UTXO.

S306, calculating the interest value of the money and/or the rented money in each block set according to the amount of the transferred money recorded in each block set and the interest weight value of the block set.

Optionally, since the equity weight value of each block set is already calculated in S304, S305 also determines the amount of the held currency and/or the amount of the leased currency, i.e. the amount of the transferred currency, of each block in each block set, at this time, for each block set, the amount of each held currency and/or leased currency recorded in each block is multiplied by the equity weight value of the block set to obtain the equity value corresponding to the held currency and/or the leased currency, and then the equity values corresponding to the held currency and/or the leased currency in the block set are summed up to obtain the equity value of the held currency and/or the leased currency of the block set as the equity value of the block set.

S307, the equity value of each block set is accumulated to determine the equity value of the held currency and/or the rented currency.

Optionally, the interest values of the block sets determined in S306 are accumulated, that is, the interest values of the held money of the block sets are accumulated to determine the interest value of the held money; and/or accumulating the interest values of the rented money of the block sets to determine the interest value of the rented money.

S308, the interest value of the held currency and the interest value of the rented currency are accumulated to be used as the interest value of the rented account.

Optionally, if the interest values of the holding currency and the renting currency are determined in S307, the interest values of the holding currency and the renting currency determined in S307 are accumulated at this time to serve as the interest values of the renting account; if the determined value of the interest in the held money is only the value of the interest in the held money in S307, the value of the interest in the held money determined in S307 may be directly used as the value of the interest in the leased account; if the determined S307 is only the interest value of the rental money, the interest value of the rental money determined in S307 may be directly used as the interest value of the rental account.

s309, according to the interest value of the leased account, initiating a block-out node competition transaction request based on the interest value.

According to the technical scheme of the embodiment of the application, when the equity weight value is determined, the block chain is divided into a plurality of block sets by taking the set number of blocks as a unit, and the equity weight value is determined for the transferred money in each block set, so that the calculation amount for calculating the equity weight value is greatly reduced. And representing the duration of the money transferred into the block set by the distance between each block set and the current block, wherein the larger the distance is, the larger the corresponding equity weight value is. The condition that the rights and interests of the malicious nodes are improved by frequently transferring or leasing the money in a short period is well prevented, and the frequent attack of the malicious nodes on the consensus mechanism is reduced. And when the equity value is calculated, the rented money and the held money in the transferred money are quickly and accurately distinguished by checking the transferred account field in the UTXO, so that the equity value calculating efficiency is further improved.
