Background
The consensus mechanism is an important guarantee for normal operation of the blockchain system, and has become a hot research content in the current blockchain technology. High security, high speed and low resource consumption are core goals of consensus mechanism research design.
The common chain is usually realized by executing the intelligent contract, and the intelligent contract not only comprises verification of the correctness of the application layer data, but also comprises data consistency judgment during the bottom layer storage. This tightly coupled design results in a consensus algorithm with very low extensibility, creating a limitation on building flexible blockchain applications.
Another idea of consensus mechanism research is to combine multiple consensus mechanisms. BentovI et al in 2014 proposed proof of Activity (PoA) that a balance was found between security and resource consumption based on PoW and PoS. The NEO platform in 2016 proposed a dBFT consensus mechanism. The dBFT consensus mechanism is a combination of a PoS algorithm and a PBFT algorithm, wherein a part of accounting nodes are selected from a large range of nodes by using the PoS algorithm, and then the accounting nodes are commonly known by using the PBFT algorithm. The dBFT consensus mechanism solves the problem that the PoS algorithm consensus time is long and the problem that the PBFT algorithm expansibility is poor, but whether the dBFT consensus mechanism is an action proof or a dBFT consensus mechanism, the transaction between nodes is verified, a large amount of computation resources are occupied, the transaction processing speed is influenced, and therefore the safety of the consensus mechanism is a big problem of a quick consensus scheme under the condition of low resource consumption.

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings, in which it is apparent that the embodiments described below are some, but not all embodiments of the invention.
Referring to fig. 1, in some embodiments of the present invention, there is provided a blockchain-based identity authentication fast consensus method including:
and step S100, distributing weight values to the block chain link points through the service group, and obtaining node grades of the block chain nodes according to the weight values of the block chain nodes.
And step 200, performing network slicing through node grades of all the blockchain nodes to obtain a plurality of blockchain network slices.
Step S300, carrying out internal consensus and internal election of block chain nodes on each block chain network fragment to obtain common committee members of each block chain network fragment; all common committee members constitute the common committee.
Step 400, selecting a verification algorithm by a common committee to obtain a consensus verification algorithm and generating an identity signature of the consensus verification algorithm.
And S500, carrying out transaction data transmission in the block chain network fragment and transaction data transmission between the block chain network fragments according to the consensus verification algorithm and the identity signature of the consensus verification algorithm.
The verification algorithm can comprise a symmetric encryption algorithm and an asymmetric encryption algorithm, the symmetric encryption algorithm is used for encrypting the verification message, and the sending node and the receiving party can encrypt and decrypt the verification message only by holding the same secret key, so that the verification algorithm has the characteristics of shorter secret key, high encryption speed and simple encryption processing, and is suitable for occasions of encrypting a large amount of data; the asymmetric encryption algorithm requires two keys, a public key and a private key. The public key and the private key are a pair, if the public key is used for encrypting the data, the data can be decrypted only by the corresponding private key, so that the asymmetric encryption algorithm is not suitable for the occasion of encrypting a large amount of data. The embodiment can select a proper verification algorithm according to the scene requirement, but the verification algorithm cannot be considered as a limitation of the invention, for example, an asymmetric encryption algorithm can select an RSA encryption algorithm, a DSA encryption algorithm and an ECDSA encryption algorithm; RSA encryption algorithm RSA is an asymmetric key encryption technology which is widely applied at present and has long history, and RSA is the most widely applied digital encryption and signature technology at present because of difficult cracking. The security level depends on the length of the key, the currently dominant selectable key is 1024 bits, 2048 bits, 4096 bits, etc., and theoretically, the longer the key is, the more difficult to crack, so that the industry recommends using 2048 bits or more, but the 2048 bits of key is enough to be secure, and the longer key is safer, but the higher the performance cost is. DSA encryption algorithm: the digital signature algorithm is different from the RSA encryption algorithm in that the DSA encryption algorithm can only be used for digital signature, and cannot encrypt and decrypt data, and the security is equivalent to that of RSA, but the performance is faster than that of RSA. The ECDSA encryption algorithm is a combination of elliptic curve cryptography and DSA encryption algorithm, compared with an RSA algorithm, the ECDSA encryption algorithm has the advantages that smaller keys can be used by ECC, higher efficiency is achieved, higher safety guarantee is provided, the safety of 256-bit ECC keys is said to be equal to 3072-bit RSA keys, and compared with common DSA, the ECDSA encryption algorithm has the advantages that part of factors use the elliptic curve algorithm in the process of calculating the keys.
Firstly, distributing weight values to block chain link points through a service group, and calculating node grades of block chain nodes to prevent malicious node attacks; then network slicing is carried out according to the node grade of the block chain node, so that the high-quality block chain link points are ensured to be in the same network slice area as much as possible, and a better transaction environment is provided for the high-quality block chain node; then, each block chain network fragment is subjected to internal consensus and internal election of block chain nodes to obtain common committee members of each block chain network fragment, so that the common committee members can make decisions on representing opinion of the block chain network fragment, and the consensus time of the block chain nodes is reduced; secondly, the committee performs selection of the verification algorithm to obtain a consensus verification algorithm and generate an identity signature of the consensus verification algorithm, transaction data can be encrypted and decrypted through the consensus verification algorithm, and the transaction data cannot be decrypted without nodes achieving the consensus verification algorithm, so that transaction verification complexity among blockchain nodes is reduced, and a large amount of computing resources for transaction verification are saved; and finally, carrying out quick consensus of the blockchain nodes through a consensus verification algorithm and an identity signature of the consensus verification algorithm, so that the speed of transaction data transmission in the blockchain network area and transaction data transmission between the blockchain network areas is improved, and the security of the transaction data is ensured through the consensus verification algorithm and the identity signature.
Referring to fig. 2, in some embodiments of the present invention, assigning weight values to block link points through a service group, and obtaining node levels of block chain nodes according to the weight values of the block chain nodes includes:
step S101, calculating the weight value of the block chain node in a preset period according to the block outlet time, the block utilization rate, the node activity and the voting effective rate of the block chain node in the preset period of the service group.
Step S102, calculating to obtain the node grade of the block chain node through the weight value of the block chain node in a preset period and the real-time dynamic weight value of the block chain link point; the real-time dynamic weight value of the block chain link point is calculated by the real-time online time of the block chain node, the real-time proposed block number, the total capacity fraction consumed by creating the legal block in real time and the real-time effective voting fraction.
It should be noted that, in this embodiment, the block-out time, the block utilization rate, the node activity and the voting effective rate of the blockchain node in the preset period of the service group are calculated according to the past behavior of the blockchain node, the preset period can be formulated according to the actual scene requirement, and meanwhile, the real-time dynamic weight value of the blockchain node is calculated according to the service group where the blockchain node is located in real time, and is updated in real time according to the real-time behavior.
According to the embodiment, the weight value of the past behavior is calculated through the block outlet time, the block utilization rate, the node activity and the voting effective rate of the block chain node in the preset period, the real-time dynamic weight value of the block chain node is calculated, and the real-time performance, the real-time performance and the accuracy of the node grade of the block chain node are guaranteed by combining the block outlet time, the block utilization rate, the node activity and the voting effective rate of the block chain node.
Referring to fig. 3, in some embodiments of the present invention, network slicing is performed through node levels of all blockchain nodes to obtain a plurality of blockchain network slices, including:
step S201, a node identity relation mapping table is obtained according to the node grades of all the blockchain nodes.
The node identity relation mapping table can acquire elements by utilizing the index of the array, the time complexity is low, the node identity relation mapping table can trace the source blockchain node, and the behaviors of the blockchain nodes are mutually supervised to a certain degree.
Step S202, network slicing is carried out according to the node identity relation mapping table, and a plurality of blockchain network slices are obtained.
The blockchain network patch divides a blockchain network having a plurality of nodes into a plurality of subnetworks, each subnetwork including a portion of the nodes, i.e., a segment. Meanwhile, the transactions in the network can be divided into different fragments for processing, so that each node only needs to process a small part of incoming transactions, and different nodes can process the transactions in parallel, namely the concurrency of transaction processing and verification can be increased, and the throughput of the whole network is improved. The throughput is multiplied, so that the problem of transaction congestion is effectively solved, and the transfer fee is reduced.
Referring to fig. 4, in some embodiments of the present invention, the transmission of transaction data within and between blockchain network tiles is performed in accordance with a consensus verification algorithm and an identity signature of the consensus verification algorithm, comprising:
and step S510, locally calculating the transaction data according to the consensus verification algorithm to obtain a verification result.
And step S520, the verification and verification result and the identity signature of the consensus verification algorithm are sent to the inside of the blockchain network fragment of the transaction data.
And step S530, carrying out identity signature recognition of a consensus verification algorithm on all nodes in the block chain network fragment to obtain the node achieving identity signature consensus.
And S540, decrypting and verifying the verification result by the node achieving identity signature consensus through a consensus verification algorithm corresponding to the identity signature consensus to obtain transaction data.
Step S550, when the transaction data transmission between the block chain network segments is required, the common committee member of each block chain network segment is used for carrying out the identity signature recognition of the consensus verification algorithm, verifying whether the consensus of the verification algorithm is achieved between the block chain network segments, and if the consensus of the verification algorithm is achieved between the block chain network segments, transmitting the verification result to the block chain network segment achieving the consensus of the verification algorithm.
It should be noted that, the common committee records the identity of the common committee member, the result of the blockchain node managed by the common committee member, and the state balance of each address account; the block chain network fragment area is mainly formed by packing and recording the transaction which is responsible for processing the fragment by the common committee member; the blocks stored by each validation node are the blockchain network slices and the common committee of its corresponding slice.
Illustratively, the blockchain system is configured with a blockchain network slice including 3 common committee member leaders, which are respectively a first blockchain network slice, a second blockchain network slice and a third blockchain network slice, wherein the first blockchain network slice includes 1 common committee member and 3 blockchain nodes, the numbers of the 3 blockchain nodes are blockchain node 1, blockchain node 2 and blockchain node 3, the numbers of the blockchain nodes in the second blockchain network slice are common node 4, common node 5 and common node 6, and the blockchain nodes in the third blockchain network slice are common node 7, common node 8 and common node 9. The common committee member generates transaction data to be decrypted and encapsulates the transaction data to be decrypted in a preparation packet, and then sends the preparation packet to the common node blockchain node 1, the blockchain node 2 and the blockchain node 3. The common committee member and the common identification verification algorithm obtained by voting in advance through the blockchain node 1, the blockchain node 2 and the blockchain node 3 can decrypt the transaction data, and the common identification verification algorithm can be verified through the identity signature, so that the security of the transaction data transmission is improved, and more computing resources are released.
In the embodiment of the invention, the block chain link points are segmented, and the leader nodes between the segments are identified, so that the identification process between all nodes can be converted into the identification process between a small number of identification nodes among each node group, thereby greatly reducing the identification complexity, reducing the communication pressure and increasing the node scale of the alliance chain; when each consensus node performs consensus in the block chain network patch to which the consensus node belongs, the subsequent consensus process can be executed only by waiting for the consensus state sent by other consensus nodes in the block chain network patch, and the subsequent consensus process can be executed without waiting for the consensus state party sent by all the consensus nodes in the block chain system like the prior art, so that the waiting time required by the consensus process of each consensus node can be greatly reduced, and the consensus efficiency of the block chain system is greatly improved; and furthermore, when the transaction is carried out in the prior art, all nodes are required to mutually verify, and verification information is transmitted, verification information is received and replied, and the like for multiple information transmission is verified, so that the consensus time is greatly shortened, a large amount of computing resources are released, and the block chain procedure cost is reduced.
Referring to fig. 5, in some embodiments of the present invention, after the selection of the authentication algorithm by the common committee, the obtaining of the consensus authentication algorithm and the generation of the identity signature of the consensus authentication algorithm, the blockchain-based rapid consensus method for identity authentication further includes:
and step S310, taking the common committee member as a supervision node, and acquiring other nodes of each block chain network fragment except the common committee member.
Step S320, calculating node grades of other nodes, and selecting other nodes exceeding a node grade threshold to perform downward signing of identity signatures of a consensus verification algorithm; the supervising node is used for carrying out trust supervision on other nodes which exceed the threshold value of the node level in the trust list through the node level.
It should be noted that, in order to cope with the needs of task scenarios, the present embodiment provides a method capable of further reducing the complexity of consensus and reducing the consensus time, by using a common committee member as a supervision node, other nodes issue the identity signature of the consensus verification algorithm downwards, and at the same time, the nesting behavior issued downwards may not be limited.
The complexity of consensus is further reduced and the consensus time is reduced by further utilizing other nodes to issue downwards, and meanwhile, the security of issuing downwards by other nodes is enhanced by utilizing common committee members as supervision nodes.
Referring to fig. 6, in some embodiments of the invention, incorporating other nodes exceeding a node level threshold into a trust list performs trust supervision by node level, including:
and step S321, giving random numbers to other nodes in the trust list according to the verifiable random function.
And step S322, grouping the random numbers through a lottery algorithm to obtain the grouping of other nodes corresponding to the random numbers.
Step S323, performing trust supervision on other nodes of each group through one-to-one correspondence between each supervision node, and performing random number reassignment in a preset period.
It should be noted that the verifiable random function is essentially a pseudo-random function with a verification function. For a particular input and the private key of the inputter, the verifiable random function outputs a random number and a certificate, and the verifier verifies whether the random number was generated by the input by the output of the random number, the certificate, and the input. This process does not have to expose the private key of the inputter and is therefore secure. The verifiable random function satisfies verifiability, uniqueness, and pseudo-randomness. Illustratively, the message is signed using an RSA digital signature algorithm, and then a hash function is used to calculate the digital signature hash value. Different digital signatures can be obtained for different messages through an RSA digital signature algorithm, so that different random numbers are obtained, and in addition, the signature can be checked through an RSA verification algorithm, so that the validity of the random numbers is judged.
The occurrence of the brining behavior of the supervision node is reduced through the verifiable random function and the lottery algorithm, so that the behavior of issuing downwards by other nodes is safer, and the guarantee is provided for the transaction data transmission of the block chain area.
Referring to fig. 7, in some embodiments of the present invention, trust supervision by each supervising node for each group of other nodes one-to-one includes:
step S3231, the ordered transactions are read according to the kafka1 cluster.
Step S3232, calculating node grades of other nodes corresponding to the transaction.
And step S3233, setting eliminated node grades corresponding to different strength security requirements, eliminating other nodes and bringing new nodes exceeding a node grade threshold into a trust list.
And monitoring other nodes in real time through the eliminated node level, continuously eliminating other nodes lower than the eliminated node level, and incorporating new nodes exceeding the node level threshold into a trust list for supplementing, thereby ensuring the normal operation of the blockchain system and ensuring the safety of transaction data transmission.
