Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the financial transaction field, block link points which are qualified for packaging transaction assembly blocks are determined mainly by adopting a random sampling algorithm; while the random sampling algorithm includes a workload certification algorithm and a leader election algorithm.
The proof of workload algorithm requires a random hash operation when determining blockchain nodes that qualify for a packed transaction assembly block, and introduces a scan operation for a particular value, such as hash function SHA-256, when doing a random hash operation, the random hash value starts with one or more preambles 0. As the number of preambles 0 increases, the amount of effort required to find this solution will increase exponentially, while checking the result requires only one random hash operation. A random number is appended to the block data, the random number being such that a desired number of 0 s appear for a random hash value given the block data. This random number is found by iterative attempts until found, thus constructing a proof of workload algorithm. The information of the block data cannot be changed unless there is a block link point to accomplish a considerable amount of work again. Since the block data following the block data in the blockchain is linked to the block data, the entire workload of all the block data following the block data in the blockchain needs to be completed again in order to change the information in the block data.
Meanwhile, the workload certification algorithm also solves the problem of who is most when voting in a collective manner. If it is determined that most of the ways are based on IP addresses, one IP address for one ticket, the algorithm is destroyed if someone has the right to assign a large number of IP addresses. The nature of the workload certification algorithm is a CPU ticket. The "majority" decision is expressed as the longest chain, as the longest chain represents the greatest amount of work. If most CPUs are in honest blockchain node control, honest chains will lengthen at the fastest speed and go beyond other competing chains. If it is desired to modify block data within a block chain that has already occurred, an attacker must re-complete the workload of the block data plus the workload of all the block data after the block data and eventually catch up with and surpass the workload of the honest block chain nodes.
Another problem is that the speed of operation of hardware is growing at high speeds, and the extent to which blockchain nodes participate in the network varies. To solve this problem, the difficulty of the workload certification will be determined by a moving average target method, i.e. the difficulty is directed to a certain predetermined average of the rate at which the block data is generated per hour. If the block data is generated too fast, the difficulty increases.
In order to effectively achieve a distributed consensus, a good random sampling function has several features:
fairness: the function should distribute leader elections among the most extensive participants possible;
investment: the cost of controlling the leader election process should be proportional to the value obtained from it;
and (3) verification: it should be relatively simple for all participants to verify whether the leader is legally selected.
The leader election algorithm uses new secure CPU instructions widely available in consumer and enterprise processors. These characteristics are used by the leader election algorithm to ensure the security and randomness of the leader election process without the need for high energy costs and specialized hardware investments in most attestation algorithms.
The basic work of the leader election algorithm is as follows:
1. each blockchain verification node requests a wait time from the trusted function enclave;
2. for the specific transaction block data, selecting the block chain verification node with the shortest waiting time as a leader;
3. the function CreateTimer creates a timer for the transaction block, which timer guarantees creation by the trusted function;
4. the function CheckTimer verification timer is created by a trusted function that, if the timer has expired, will create a proof that can be used to verify that the blockchain verification node did not assert the leader role until the allotted time.
The leader election algorithm meets the criteria of a good random sampling algorithm. It randomly distributes leader elections among all blockchain verification nodes, the distribution of which is similar to other sampling algorithms. The probability of selection is proportional to the resource provided, where the resource is a general purpose processor with a trusted execution environment. Performing the certification provides a certification for certifying that the certificate was created in the trusted function, and a time certification that the blockchain verifying node has waited for the allocation. In addition, the lower participation cost increases the total number of the block chain verification nodes, and the robustness of the consistency algorithm is improved.
Both of the above consensus algorithms require a significant amount of processor resources to reach consensus, which results in the problem of low practicality of existing blockchain systems.
In order to improve the practicability of a blockchain system, the embodiment of the invention provides the blockchain system, and a data uplink method, a device, equipment and a medium.
Example 1:
FIG. 1 is a block chain system according to an embodiment of the present invention, the block chain system comprising: a first blockchain node 11 and at least one second blockchain node 12;
the first blockchain node 11 is configured to broadcast first transaction data in a common period, and receive second transaction data broadcast by each second blockchain node; according to each acquired transaction data, if the transaction data is confirmed to be the block chain node for performing transaction for the first time in the consensus period, the acquired transaction data in the consensus period is packaged into block data for transmission, and the block data is connected after the last block data of the local record;
Each second blockchain node 12 is configured to broadcast second transaction data in the common identification period, receive the first transaction data broadcast by the first blockchain node and second transaction data broadcast by other second blockchain nodes except for the second blockchain node, and if it is determined that each obtained transaction data is not the blockchain node that performs the first transaction in the common identification period, receive the block data sent by other blockchain nodes except for the second blockchain node and connect the second blockchain node to the last block data recorded locally.
The blockchain system may be a point-To-point (P2P) network consisting of a plurality of blockchain links. P2P is an application layer protocol running on top of the transmission control protocol (Transmission Control Protocol, TCP), the blockchain nodes in a blockchain system may peer to each other, there being no central blockchain node in the system, so each blockchain node may randomly connect to other blockchain nodes. In the blockchain system, each blockchain node can be internally provided with a preset database, each blockchain node jointly maintains a public account book in the blockchain system through the preset database, and the preset database in the blockchain node can store the blockdata in the blockchain system; the block data comprises a block header and a block body, the block header comprises information such as a hash value of the previous block, a hash value of the current block, a block height of the current block, a time stamp and the like, and the block body comprises transaction data such as transaction data generated by processing transactions by a block chain node in a block chain system.
In the embodiment of the present invention, a plurality of blockchain nodes may be included in the blockchain system, where the first blockchain node 11 is any blockchain node in the blockchain system that may receive transaction data in the network, and the blockchain node in the blockchain system may be a blockchain node independently used as a server, or may be a blockchain node connected to a server by a tax disc, and in particular, the embodiment of the present invention is not limited thereto.
Wherein the first transaction data may be transaction data submitted by a terminal device to the first blockchain node 11; the first transaction data may also be transaction data submitted to the first blockchain node 11 based on clients in the terminal device.
The first blockchain node 11 is configured to broadcast first transaction data during a consensus period, where the consensus period is a time required for all blockchain links in the blockchain system to complete a data interaction and agree, and the consensus of all blockchain links in the blockchain system is a blockchain node that determines a qualification of packaging transaction assembled blocks in the blockchain system; specifically, in the embodiment of the present invention, the consensus among all the blockchain nodes in the blockchain system refers to determining the blockchain node that is the first to transact.
Thus, the first blockchain node 11 broadcasts first transaction data in a common period, and other blockchain nodes in the blockchain system than the first blockchain node 11 can receive the broadcasted first transaction data, and the first blockchain node 11 also receives transaction data broadcast by other blockchain nodes in the blockchain system than itself, namely second transaction data broadcast by each second blockchain node 12 in the blockchain system.
After receiving the second transaction data broadcast by each second blockchain node 12, the first blockchain node 11 can determine whether the first blockchain node is the blockchain node for performing transactions for the first time in the common period according to the transaction time contained in each obtained transaction data, that is, determine whether the first transaction data of the first blockchain node 11 has the transaction data with the earliest transaction time in all the transaction data, and if the first transaction data has the transaction data with the earliest transaction time in all the transaction data, determine that the first blockchain node 11 is the blockchain node for performing transactions for the first time in the common period.
When the first blockchain node 11 determines itself to be the first blockchain node to conduct transactions in the consensus period, the first blockchain node 11 determines itself to be the blockchain node with qualification of packaging transaction assembly blocks in the consensus period, and the first blockchain node 11 obtains the accounting right of the blockchain in the current consensus period, that is, the first blockchain node 11 connects new block data after the locally recorded block data.
The first blockchain node 11 packages all transaction data acquired in the current consensus period into one block data to be sent, and connects the block data after the last block data recorded locally.
Each second blockchain node 12, when the first blockchain node 11 broadcasts first transaction data in a common period, each second blockchain node 12 also broadcasts second transaction data in the same common period, and receives transaction data broadcast by other blockchain points in the blockchain system except itself, namely, the first transaction data broadcast by the first blockchain point and the second transaction data broadcast by other second blockchain nodes except itself.
The second blockchain node 12 obtains the accounting right from the blockchain node with the qualification of packaging transaction assembly blocks when determining that the second blockchain node is not the first blockchain node for transaction in the consensus period according to each transaction data acquired by the second blockchain node, and the second blockchain node 12 receives the blockdata sent by the other blockchain nodes except the second blockchain node and is connected with the blockdata after the last locally recorded blockdata, namely, the blockchain recorded by the second blockchain node 12 is also updated.
Because in the embodiment of the invention, each block chain node in the block chain system broadcasts first transaction data in a consensus period and receives second transaction data broadcast by other block chain nodes; and if the self is confirmed to be the block chain node for carrying out transaction for the first time in the common identification period according to each transaction data acquired locally, packaging the acquired transaction data in the common identification period into first block data for transmission, and connecting the first block data after the last block data recorded locally. Because each blockchain node judges whether the blockchain node is the blockchain node for carrying out transaction for the first time in the consensus period, the blockchain node for carrying out transaction for the first time in the consensus period is determined to be the blockchain node with qualification of packaging transaction assembly blocks in the consensus period, the processor resource consumed by carrying out a large amount of calculation is saved, and the practicability of the blockchain system is improved.
Example 2:
in order to ensure the integrity of the packed transaction data, in the embodiment of the present invention, the first blockchain node 11 is further configured to package the acquired transaction data in the common identification period and the transaction data not packed in the previous common identification period.
The first blockchain node 11 is a blockchain node in the blockchain system that qualifies for packaging transaction assembly blocks when the first blockchain node 11 determines itself to be the first blockchain node to conduct transactions in the blockchain system, the first blockchain node 11 obtains accounting rights for blockchains in the consensus period, and the first blockchain node 11 concatenates the blockdata after packaging transaction data into the blockdata and after the last blockdata is locally recorded.
Specifically, in order to ensure the integrity of the packaged transaction data, the packaged transaction data includes transaction data in the current consensus period and transaction data not packaged in the last consensus period, the first blockchain node 11 packages the obtained transaction data in the consensus period and the transaction data not packaged in the last consensus period into block data, and connects the block data after the last block data locally recorded by the first blockchain node 11.
Example 3:
in order to ensure the security of the packaged transaction data, in the embodiment of the present invention, the first blockchain node 11 is further configured to verify the obtained transaction data in the consensus period if it is determined that the first blockchain node performs the transaction in the consensus period is the blockchain node, and package the transaction data passing the verification.
The first blockchain node 11 confirms itself as the blockchain node that first performs the transaction in the consensus period, and before the first blockchain node 11 packages the transaction data in the consensus period, the first blockchain node also needs to verify the transaction data in the consensus period, where the verification specifically refers to determining whether the transaction data in the consensus period is changed.
The first blockchain node 11 verifies the transaction data in the common period using prior art methods.
Specifically, the transaction data includes original data information of the transaction data, and signature information generated by encrypting the transaction data by using a private key by the second blockchain node 12 broadcasting the transaction data; based on the public key of the second blockchain node 12 broadcasting the transaction data, the first blockchain node 11 may decrypt the signature information of the transaction data and determine a first hash value of the transaction data. The first blockchain node 11 performs hash operation on the transaction data again to obtain a second hash value of the transaction data, judges whether the second hash value is consistent with the first hash value, and if so, the transaction data passes verification; if the second hash value is inconsistent with the first hash value, the transaction data verification is not passed.
Example 4:
in order to ensure the accuracy of the transaction data in the block data, in the embodiment of the present invention, the second blockchain node 12 is further configured to verify the transaction data included in the block data after receiving the block data sent by other blockchain nodes except the second blockchain node, and connect the block data that passes the verification after the last block data recorded locally.
After receiving the block data sent by other block chain nodes except the second block chain node 12, the second block chain node verifies the transaction data contained in the block data, namely, judges whether the transaction data contained in the block data is changed or not.
The second blockchain node 12 verifies the transaction data contained in the blockdata using prior art methods.
Specifically, the second blockchain node 12 decrypts the signature information of the transaction data included in the block data by using the public key of the blockchain node broadcasting the block data, where the blockchain node broadcasting the block data is any blockchain node except itself in the blockchain system, and specifically may be the first blockchain node 11 or any second blockchain node 12 except itself.
A first hash value of the transaction data may be determined based on the decryption result. The second blockchain node 12 performs hash operation on the transaction data again to obtain a second hash value of the transaction data, judges whether the second hash value is consistent with the first hash value, and if so, the transaction data passes verification; if the second hash value is inconsistent with the first hash value, the transaction data verification is not passed.
Since the block data includes at least one transaction data, when all transaction data in the block data passes the verification, the block data passes the verification; when any transaction data in the block data fails to pass the verification, the block data fails to pass the verification.
The second blockchain node 12 concatenates the verified block data after the last block data recorded locally.
Example 5:
fig. 2 is a schematic process diagram of a data uplink method according to an embodiment of the present invention, where the process includes the following steps:
s201: first transaction data broadcast during a common period and second transaction data broadcast by each second blockchain node are received.
The method is applied to a first block chain node in the block chain system, wherein the first block chain node can be any block chain node in the block chain system, the first block chain node broadcasts first transaction data in a common identification period, and simultaneously receives second transaction data broadcast by every second block chain node except the first block chain node in the block chain system, namely, each block chain node in the block chain system broadcasts transaction data in a common identification period.
S202: and according to each acquired transaction data, if the acquired transaction data is confirmed to be the block chain node for performing the transaction for the first time in the common recognition period, packaging the acquired transaction data in the common recognition period into block data for transmission, and connecting the block data after the last block data of the local record.
To determine the blockchain node that qualifies for a packed transaction assembly block, the first blockchain node also needs to determine if itself is the first blockchain node to transact within the consensus period.
Therefore, the first blockchain node can determine whether the first blockchain node is the blockchain node for performing the transaction for the first time in the consensus period according to the transaction time contained in each transaction data, specifically, whether the first transaction data of the first blockchain node comprises the transaction data with the earliest transaction time in all the transaction data or not is judged, if so, the first blockchain node confirms that the first blockchain node is the blockchain node for performing the transaction for the first time in the consensus period.
When the first blockchain node confirms that the first blockchain node is the blockchain node for the first transaction in the common identification period, the first blockchain node 11 determines that the first blockchain node is the blockchain node with the qualification of packaging transaction assembly blocks in the common identification period, and the first blockchain node packages all transaction data obtained in the common identification period into blockdata. To achieve all blockchain nodes updating the saved blockchain, the first blockchain node sends the packed blockdata and the first blockchain node concatenates the blockdata after the last blockdata locally recorded.
To ensure the integrity of the packaged transaction data, after the identifying itself as the blockchain node that first conducts the transaction in the consensus period, the method further includes:
and packing the acquired transaction data in the consensus period and the transaction data which are not packed in the last consensus period into block data to be sent.
The first blockchain node is a blockchain node qualified for packaging transaction assembly blocks in the blockchain system when the first blockchain node is determined to be the first blockchain node for transaction in the blockchain system, the first blockchain node obtains the accounting rights of the blockchain in the common identification period, and the first blockchain node packages transaction data into block data and connects the block data after the last block data is locally recorded.
Specifically, in order to ensure the integrity of the packaged transaction data, the packaged transaction data comprises transaction data in the current consensus period and non-packaged transaction data in the last consensus period, and the first block link point packages the obtained transaction data in the consensus period and the non-packaged transaction data in the last consensus period into block data; and concatenating the packetized block data after the last block data recorded locally at the first blockchain node.
In order to ensure the security of the packed transaction data, after the block chain node which is the first to conduct the transaction in the consensus period is confirmed, the method further comprises:
and verifying the obtained transaction data in the consensus period, and packaging the transaction data passing verification.
The first blockchain node confirms that the first blockchain node is the blockchain node for carrying out transaction in the consensus period, and before the first blockchain node packages transaction data in the consensus period, the first blockchain node also needs to verify the transaction data in the consensus period, and the verification specifically refers to judging whether the transaction data in the consensus period is changed or not.
The method for verifying the transaction data in the consensus period by the first blockchain node adopts the method in the prior art.
Specifically, the transaction data includes original data information of the transaction data and signature information generated by encrypting the transaction data by using a private key by a second blockchain node broadcasting the transaction data; the first blockchain node may decrypt the signature information of the transaction data and determine a first hash value of the transaction data based on a public key of a second blockchain node broadcasting the transaction data. The first block chain node carries out hash operation on the transaction data again to obtain a second hash value of the transaction data, judges whether the second hash value is consistent with the first hash value, and if so, the transaction data passes verification; if the second hash value is inconsistent with the first hash value, the transaction data verification is not passed.
In the embodiment of the invention, the first blockchain node can determine whether the first blockchain node is the blockchain node for carrying out transaction for the first time in the consensus period according to the transaction time contained in each acquired transaction data, and when the first blockchain node is determined to be the blockchain node for carrying out transaction for the first time in the consensus period, the first blockchain node packages all the transaction data acquired in the current consensus period into one blockdata to be transmitted, and the last blockdata recorded locally is connected with the blockdata. Thereby enabling the addition of transaction data within a consensus period to the blockchain and saving a significant amount of processor resources consumed by the computation.
Example 6:
fig. 3 is a schematic process diagram of a data uplink method according to an embodiment of the present invention, where the process includes the following steps:
s301: broadcasting second transaction data in the consensus period, and receiving the first transaction data broadcast by the first blockchain node and second transaction data broadcast by other second blockchain nodes except the first transaction data and the second transaction data broadcast by the second blockchain node.
The method is applied to any second blockchain node in the blockchain system except the first blockchain node, the second blockchain node 12 broadcasts second transaction data in a consensus period, and the consensus period is the same as the consensus period of the first blockchain node broadcasting the first transaction data.
And the second blockchain node receives the transaction data broadcast by other blockchain nodes except the second blockchain node in the blockchain system, namely the second blockchain node receives the first transaction data broadcast by the first blockchain node and the second transaction data broadcast by other second blockchain nodes except the second blockchain node.
S302: and according to each acquired transaction data, if the block chain node is not the block chain node for performing the first transaction in the consensus period, receiving the block data sent by other block chain nodes except the block chain node and connecting the block data with the last block data recorded locally.
And the second blockchain node obtains the accounting right by the blockchain node with the qualification of packaging transaction assembly blocks when determining that the second blockchain node is not the first blockchain node for transaction in the consensus period according to each transaction data acquired by the second blockchain node, receives the blockdata sent by other blockchain nodes except the second blockchain node, and is connected with the blockdata after the last locally recorded blockdata, namely the blockchain recorded by the second blockchain node is also updated.
In order to ensure the accuracy of the transaction data in the block data, the receiving the block data sent by other block chain nodes except the block data and connected to the last block data recorded locally includes:
and after receiving the block data sent by other block chain nodes except the block data, verifying the transaction data contained in the block data, and connecting the block data passing verification after the last block data of the local record.
After receiving the block data sent by other block chain nodes except the second block chain node, the second block chain node verifies the transaction data contained in the block data, namely judges whether the transaction data contained in the block data is changed or not.
The second blockchain node verifies the transaction data contained in the blockdata using prior art methods.
Specifically, the second blockchain node decrypts the signature information of the transaction data contained in the blockdata by adopting a public key of a blockchain node broadcasting the blockdata, wherein the blockchain node broadcasting the blockdata is any blockchain node except for the second blockchain node in the blockchain system, and the second blockchain node can be a first blockchain node or any second blockchain node except for the second blockchain node.
A first hash value of the transaction data may be determined based on the decryption result. The second block chain node carries out hash operation on the transaction data again to obtain a second hash value of the transaction data, judges whether the second hash value is consistent with the first hash value, and if so, the transaction data passes verification; if the second hash value is inconsistent with the first hash value, the transaction data verification is not passed.
Since the block data includes at least one transaction data, when all transaction data in the block data passes the verification, the block data passes the verification; when any transaction data in the block data fails to pass the verification, the block data fails to pass the verification.
The last block data locally recorded by the second blockchain node is then connected with the block data passing verification.
Because in the embodiment of the invention, the second blockchain node can determine whether the second blockchain node is the blockchain node for performing the first transaction in the common period according to the transaction time contained in each acquired transaction data, and when the second blockchain node is determined not to be the blockchain node for performing the first transaction in the common period, the second blockchain node receives the blockdata sent by other blockchain nodes except the second blockchain node and is connected with the blockdata after the last locally recorded blockdata. Thereby enabling the addition of transaction data within a consensus period to the blockchain and saving a significant amount of processor resources consumed by the computation.
