Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The invention provides a synchronization method of blockchain transaction pool information, in an embodiment of the synchronization method of blockchain transaction pool information, referring to fig. 1, the synchronization method of blockchain transaction pool information is applied to a first blockchain node, and the synchronization method of blockchain transaction pool information comprises the following steps:
step S10, when detecting that the connection with other second block chain link points is detected, acquiring first information of a first transaction pool corresponding to the first block chain link point and a first synchronization window time length of information synchronization between the first information and second information of a second transaction pool corresponding to other second block chain link points;
step S20, after the time length of the first synchronization window is away from the current time, whether the first information and the second information are different or not is determined;
step S30, if the first information and the second information are different, determining to perform first synchronization of information between the first transaction pool and the second transaction pool according to a first preset synchronization strategy;
step S40, if there is no difference between the first information and the second information, determining to perform second synchronization of the information between the first transaction pool and the second transaction pool according to a second preset synchronization policy, wherein the time lengths of synchronization windows corresponding to the first synchronization and the second synchronization are different.
The method comprises the following specific steps:
step S10, when detecting that the connection with other second block chain link points is detected, acquiring first information of a first trading pool corresponding to the first block chain link point and a first synchronization window time length of information synchronization between second information of a second trading pool corresponding to other second block chain link points;
it should be noted that, in this embodiment, the synchronization method for blockchain transaction pool information is applied to a first blockchain node, where the first blockchain link point belongs to a synchronization system for blockchain transaction pool information, and is a node (corresponding to one or more blockchain users) in the synchronization system for blockchain transaction pool information, the synchronization system for blockchain transaction pool information further includes a plurality of other second blockchain nodes besides the first blockchain node, and it should be noted that the first blockchain link point and the plurality of other second blockchain link points are in communication connection, where the communication connection includes a direct communication connection and an indirect communication connection, so as to perform synchronization of blockchain transaction pool information.
Specifically, when detecting a connection request of another second block link node, that is, when detecting that initial connection is performed with another second block link node, the first block link node acquires first information (specifically, pending Txs, which is transaction data that is not packed into a block link block)) of the first block link node locally corresponding to the first transaction pool, and a first synchronization window time length of information synchronization between second information of the second transaction pool corresponding to the other second block link node, where it should be noted that the first synchronization window time length may be a minimum time length of information exchange between the first block link node and another second block link node of the transaction pool, that is, the first synchronization window time length may be a unit time length t, and the first synchronization window time length is t, that is, after t passes, information exchange between the first transaction pool and the second transaction pool is triggered.
Step S20, after the time length of the first synchronization window is away from the current time, whether the first information and the second information are different or not is determined;
in this embodiment, after the first synchronization window time length is obtained from the current time, it is determined whether there is a difference between the first information and the second information, specifically, if the first information in the first transaction pool is Tx1, tx2, and Tx3 (Tx represents a transaction), and the second information is also Tx1, tx2, and Tx3, there is no difference between the first information and the second information, and if the second information is Tx1, tx2, and Tx4, there is a difference between the first information and the second information.
Specifically, the step of determining whether there is a difference between the first information and the second information after the first synchronization window time length from the current time includes:
step S21, after the time length of the first synchronization window is equal to the current time, obtaining first display data bit information obtained after the first information is forwarded to a preset bloom filter, wherein each transaction data unit in the first information is mapped to the display numerical value of the corresponding number of display data bits in the bloom filter in a preset mapping mode;
in this embodiment, after the first synchronization window time length is reached from the current time, the first information is synchronized, specifically, the first information is forwarded to a preset bloom filter, the first information is processed based on the preset bloom filter, so as to obtain first display data bit information, that is, each transaction data unit in the first information is mapped based on a preset mapping manner based on the preset bloom filter, so as to obtain display values of a corresponding number of display data bits, specifically, as shown in fig. 4, the bloom filter may be regarded as a binary vector (including a plurality of data bits) with a length of l, the initial values of the data bits are all zero, each transaction data unit is mapped to a display value of a plurality of (3) data bits in the vector by a preset mapping manner, such as a certain Hash function, which is 1 (position of the data is 1), as shown in fig. 1, tx represents a transaction, the first message includes three transaction data units Tx1, tx2, tx3, which are calculated by three preset Hash functions respectively (Tx 1 is calculated by three preset Hash functions, tx2 is calculated by three preset Hash functions, tx3 is calculated by three preset Hash functions), each transaction data unit can obtain three Hash values respectively, the display value of the data bit of the bloom filter corresponding to the three Hash values is from 0 to 1, i.e. specifically, tx1 is mapped at 2,5,7 positions of the data bit of the bloom filter, tx2 is mapped at 5,8, 10 positions of the data bit of the bloom filter, tx3 is mapped at 7,8, 11 positions of the data bit of the bloom filter, wherein the mapped 2,5,7 positions, 5,8, 10 positions, the display values corresponding to the 7,8, 11 positions constitute first display data bit information.
After each transaction data unit Tx in the first information is placed in the bloom filter, when an inquiry instruction is detected, calculating the Tx needing to be inquired again through the previous three preset Hash functions, observing whether the corresponding three data bits are 1, judging that the Tx exists if the three data bits are all 1, and otherwise, judging that the Tx does not exist in the bloom filter.
Step S22, non-existing information obtained after the other second block link points are compared with second display data bit information corresponding to the second information based on the first display data bit information is obtained;
after the second information is obtained and sent to the bloom filter, the obtained corresponding second display data bit information is the same as the process of obtaining the first display data bit information after the second information is sent to the bloom filter, and is not repeated herein, after the first display data bit information and the second display data bit information are obtained, the other second block chain nodes compare the first display data bit information with the second display data bit information (or can directly compare the first display data bit information with the second display data bit information) one by one to obtain non-existent information, wherein the non-existent information is a transaction data unit in which the second display data bit information is completely different from the first display data bit information, and the non-existent information corresponds to uncertain information, wherein the uncertain information is a transaction data unit in which the second display data bit information is possibly different from or possibly the same as the first display data bit information. Specifically, for example, the trade pools (TxPool) of the a block link point (first block link node) and the B block link point (second block link node) are TxPool1{ Tx1, tx2, tx4}, txPool2{ Tx1, tx3, tx5}, respectively, a generates bloom1 (first display data bit information) by using a bloom filter for all trade data units in the trade pools TxPool1, and sends bloom1 to B, which receives bloom1, compares bloom2 (second display data bit information) generated by all the trade data units in TxPool2 with bloom1 to obtain Tx1, tx3 may exist in TxPool1, tx5 is determined to be absent, wherein Tx5 is determined to be absent information, and Tx1 and Tx3 are uncertainty information corresponding to the absent information.
Step S23, if the non-existence information is not empty, determining that there is a difference between the first information and the second information.
If the absence information is not null, if the absence information Tx5 exists, determining that there is a difference between the first information and the second information.
It should be noted that, if there is a difference, corresponding difference information needs to be acquired, where the difference information includes non-existence information.
Step S30, if the first information and the second information are different, determining to perform first synchronization of information between the first transaction pool and the second transaction pool according to a first preset synchronization strategy;
if there is a difference between the first information and the second information, it is determined that first synchronization of information between the first transaction pool and the second transaction pool is performed according to a first preset synchronization policy, specifically, in the first preset synchronization policy, synchronization time intervals of different times of synchronization are not changed or are the same and are a first synchronization window time length, specifically, for example, if there is a difference between the first information and the second information, next synchronization is performed after a first synchronization window time length is passed, if there is a difference in information between the first transaction pool and the second transaction pool in a next synchronization process, next synchronization after the next synchronization is performed after the first synchronization window time length is passed, until there is no difference in information between the first transaction pool and the second transaction pool, then information exchange between the first transaction pool and the second transaction pool is performed based on other synchronization window time lengths, where the other synchronization window time lengths are greater than the first synchronization window time length.
Step S40, if the first information and the second information are not different, determining to perform second synchronization of the information between the first trading pool and the second trading pool according to a second preset synchronization strategy, wherein the time lengths of synchronization windows corresponding to the first synchronization and the second synchronization are different.
And if the first information and the second information are not different, determining to perform second synchronization of the information between the first transaction pool and the second transaction pool according to a second preset synchronization strategy, wherein the synchronization window time lengths corresponding to the first synchronization and the second synchronization are different, and the synchronization window time length of the first synchronization is greater than that of the first synchronization.
If there is no difference between the first information and the second information, the step of determining to perform second synchronization of information between the first transaction pool and the second transaction pool according to a second preset synchronization policy includes:
step S41, if the first information and the second information are not different, determining the continuous synchronization times of the information between the first transaction pool and the second transaction pool;
if the first information and the second information are not different, determining the continuous synchronization times of the information between the first trading pool and the second trading pool, namely determining the continuous same times of the information between the first trading pool and the second trading pool.
And S42, determining the time length of a second synchronization window according to the continuous synchronization times and the time length of the first synchronization window, and performing second synchronization according to the time length of the second synchronization window.
And determining the time length of a second synchronization window according to the continuous synchronization times and the time length of the first synchronization window, wherein the time length of the second synchronization window is obtained by multiplying the continuous synchronization times and the time length of the first synchronization window.
Specifically, for example, as shown in fig. 5, in a first step, when a first block link point and another second block link point are connected to each other, the time length of a first synchronization window is t, that is, synchronization between first information and second information is triggered after t elapses, in a second step, if there is a difference between the first information and the second information or between information of a first transaction pool and information of a second transaction pool, the corresponding adjustment window length is the time length of the first synchronization window, timing is restarted after information is exchanged, a second synchronization is triggered after t elapses, and in a third step, if there is no difference between the second exchanged information (information between the first transaction pool and the second transaction pool) at this time, the adjustment window length is changed to 2t, and a third synchronization is triggered after 2t elapses. And fourthly, if no difference exists in the information exchange for the third time, setting the length of the adjusting window to be 4t, and so on.
And fifthly, if the difference is found in any one of the third step and the fourth step, resetting the length of the adjusting window to t and restarting timing.
Specifically, if the average time of the current generation of the blockchain block is 15 seconds, 15 transactions can be processed in average per second, and if the performance of processing transactions per second and the number of new transactions generated per second are 15 to 20, that is, the transaction pool has a change of 15 to 20 transactions per second, the length of the adjustment window is set to t =1 second.
According to the method, when connection with other second block chain link points is detected, first information of a first transaction pool corresponding to the first block chain link point is obtained, and the time length of a first synchronization window of information synchronization between the first information and second information of a second transaction pool corresponding to other second block chain link points is obtained; determining whether a difference exists between the first information and the second information after the first synchronization window time length is equal to the current time; if the first information and the second information are different, determining to perform first synchronization of the information between the first transaction pool and the second transaction pool according to a first preset synchronization strategy; and if the first information and the second information are not different, determining to perform second synchronization of the information between the first transaction pool and the second transaction pool according to a second preset synchronization strategy, wherein the time lengths of synchronization windows corresponding to the first synchronization and the second synchronization are different. In the application, when a first block link point is connected with other second block link points, a first synchronization window time length is determined, information synchronization between first information corresponding to a first transaction pool and second information corresponding to second transaction pools is determined based on the first synchronization window time length, whether a difference exists between the first information and the second information is determined, and subsequent synchronization of different strategies is performed according to whether a difference exists between the first information and the second information.
Further, based on the foregoing embodiment, another embodiment of the synchronization method for blockchain transaction pool information provided by the present invention is provided, referring to fig. 2, in this embodiment, if there is a difference between the first information and the second information, the determining to perform a first synchronization step of information between the first transaction pool and the second transaction pool according to a first preset synchronization policy includes:
step S31, if the first information and the second information have difference, obtaining difference information between the first information and the second information;
if there is a difference between the first information and the second information, obtaining difference information between the first information and the second information (i.e., information existing in the second information but not existing in the first information), in this embodiment, the difference information includes non-existence information and different pieces of sub information in the uncertain information, for example, a transaction pool (txpoint) of a block chain node (first block chain node) and a B block chain node (second block chain node) is txpoint 1{ Tx1, tx2, tx4}, txpoint 2{ Tx1, tx3, tx5}, respectively, a compares all transaction data units in a transaction pool txpoint 1 with a bloom filter to generate blob 1 (first display data bit information), and sends blob 1 to B, which receives blob 1, and takes blob 2 (second display data bit information) generated by all transaction data units in txpoint 2 as the non-existence information with blob 1, to obtain that there is no existence of blob 1, 3 may exist in the transaction data units, and obtains the difference information, where Tx3 is the different pieces of sub information, tx information is obtained after the difference information and the different pieces of sub information are obtained, tx information, tx3, and the different pieces of sub information are different pieces of information.
Step S32, based on the time length of the first synchronization window and the difference information, completing the first synchronization of information between the first transaction pool and the second transaction pool.
And adjusting the first information according to the difference information to obtain first adjustment information, specifically, after a time length of a first synchronization window, adding the difference information to the first information to obtain first adjustment information, wherein it needs to be explained that second information also needs to be adjusted, and a manner of adjusting the second information is basically the same as that of adjusting the first information, and is not repeated herein, and the first synchronization of information between the first transaction pool and the second transaction pool is completed based on the time length of the first synchronization window and the difference information.

in this embodiment, because the number of bits of the data bits of the bloom filter is limited, the data bit sharing increases with the increase of the transaction data units passing through the bloom filter, so that there is a possibility of erroneous determination, for example, after the Hash calculation of Tx4, the position of Tx4 mapped on the bloom filter is calculated to be 5,7,8 bits, at this time, since three transactions Tx1, tx2, and Tx3 have one mapping bit in 5,7,8, respectively, the query Tx4 determines that the Tx exists, and the actual bloom filter has only 3 Tx bits, at this time, there is an error in determination. In order to reduce errors, in this embodiment, the first information is forwarded to a preset reversible bloom look-up table (IBLT, IBLT is characterized by that a difference between two IBLTs can be found), and the first information is processed based on a preset algorithm in the reversible bloom look-up table to generate a first look-up data bit, that is, IBLT1.

and forwarding the uncertain information corresponding to the nonexistence information to a preset reversible bloom lookup table, processing the uncertain information based on a preset algorithm, and generating a second lookup data bit IBLT2, wherein the IBLT is characterized in that the difference between two IBLTs can be found out, for example, the IBLT of one transaction data unit is IBLT3, at this time, another transaction data unit to be compared generates an IBLT4, and the IBLT3 is subtracted from the IBLT4 to obtain misjudged data through an exclusive or operation, as shown in fig. 6, the specific difference can be obtained by subtracting the two IBLTs, that is, D and X are known to be the difference between the two IBLTs.
And A3, comparing the first search data bit with the second search data bit, and determining misjudgment information so as to carry out information synchronization according to the misjudgment information.
As shown above, the first search data bit and the second search data bit are compared, and an exclusive or operation is performed to determine misjudgment information, so as to perform information synchronization according to the misjudgment information.
In this embodiment, the first information is forwarded to a preset reversible bloom lookup table, and is processed based on a preset algorithm in the reversible bloom lookup table to generate a first lookup data bit; forwarding the uncertain information corresponding to the nonexistence information to a preset reversible bloom lookup table, and processing the uncertain information based on the preset algorithm to generate a second lookup data bit; and comparing the first search data bit with the second search data bit, and determining misjudgment information so as to carry out information synchronization according to the misjudgment information.
