The following briefly introduces some concepts related to embodiments of the present application.
The blockchain technology is a brand new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secures data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data. In the block chain system, every time, transaction data generated by each participating main body is packed into a data block, the data blocks are sequentially arranged according to a time sequence to form a chain of the data blocks, each participating main body has the same data chain and cannot be tampered unilaterally, any information can be modified only by a main body agreeing party in an appointed proportion, new information can only be added, and old information cannot be deleted or modified, so that information sharing and consistent decision among multiple main bodies are realized, and the identity of each main body and the transaction information among the main bodies are guaranteed to be not tampered and are transparent.
The block chain technology is decentralized, does not depend on an additional third-party management mechanism or hardware facilities, is not subjected to central control, and except for the self-integrated block chain, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of the blockchain.
The open, blockchain technology foundation is open source, except that the private information of each party of the transaction is encrypted, the data of the blockchain is open to all people, and anyone can inquire the blockchain data and develop related applications through a public interface, so that the information of the whole system is highly transparent.
And on the basis of the agreed specifications and protocols (various mathematical algorithms such as a Hash algorithm adopted by bitcoins) the whole blockchain system does not depend on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention.
Safety, as long as 51% of all data nodes cannot be mastered, network data cannot be arbitrarily manipulated and modified, so that a block chain per se becomes relatively safe, and subjective and artificial data change is avoided.
Anonymity, unless required by legal regulations, the identity information of each block node does not need to be disclosed or verified technically, and information transfer can be performed anonymously.
The distributed account book refers to that transaction accounting is completed by a plurality of nodes distributed in different places together, and each node records a complete account, so that the nodes can participate in monitoring transaction validity and simultaneously make a proof for the node together.
Asymmetric encryption, transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed under the authorization of the data owner, so that the security of the data and the privacy of individuals are guaranteed.
The consensus mechanism, the blockchain, is a distributed (decentralized) system with traceable history and no tampering, which solves the multi-party mutual trust problem. Distributed systems necessarily face consistency problems, and the process of solving consistency problems we call consensus.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In the description of this application, "/" means "or" unless otherwise stated, for example, A/B may mean A or B. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" means one or more, "a plurality" means two or more. The terms "first", "second", and the like do not necessarily limit the number and execution order, and the terms "first", "second", and the like do not necessarily limit the difference.
At present, fixed path selection is mostly adopted for reporting block chain data, and no dynamic optimization algorithm combining block chain data reporting, the communication environment where a terminal is located, the state of a consensus node and the distance from the consensus node to the terminal is seen yet. The invention dynamically selects the data uploading path by periodically monitoring the communication environment of the cellular terminal, the state of the consensus node and the distance from the consensus node to the cellular terminal.
Fig. 1 is a schematic diagram of a block link point structure according to an embodiment of the present disclosure. The chain block comprises N block chain links, wherein the N block chain links are positioned on the same block chain platform. When the N block links perform the consensus process, the process flow shown in fig. 2 is performed. Fig. 2 is a schematic flow chart of a block chain consensus method according to an embodiment of the present disclosure, including:
s201, the block chain platform receives N pieces of node information sent by N block chain nodes.
The node information comprises an identification of a blockchain node and a calculation force P corresponding to the blockchain node, wherein N is a positive integer, and P is a constant.
The block chain platform comprises N block chain nodes, and the identifications of the N block chain nodes are as follows: n1, N2 and N3 … … Nn, wherein the calculated force P of each block chain node is as follows: p1, P2, P3 … … Pn. As shown in table 1:
TABLE 1
| Node identification | Computing power of node |
| N1 | P1 |
| N2 | P2 |
| N3 | P3 |
| …… | …… |
| Nn | Pn |
S202, the block chain platform groups the N block chain link points according to the N node information to obtain M consensus node groups.
And the block chain platform randomly divides the N block chain link points into M consensus node groups according to the identifiers of the N block chain nodes to obtain M consensus node groups, wherein M is an odd number smaller than N. Wherein, the number of the block chain nodes contained in at least M-1 consensus node groups is the same.
As shown in fig. 3, the block chain platform randomly divides the N block chain link points into M groups according to the identifiers of the N block chain link points in the N node information, so as to obtain M consensus node groups. The names of the M consensus node groups are respectively as follows: the consensus node group K1, the consensus node group K2 and the consensus node group K3 … … are the consensus node group Km. The computational power of the M consensus node groups is respectively as follows: r1, R2 and R3 … … Rm. In M common node groups, M-1 common node groups include A ═ N/M blockchain nodes, and 1 common node group includes B ═ N-A (M-1) blockchain nodes, where N/M is rounded up to obtain A, and B may be equal to A. As shown in table 2:
TABLE 2
For example: the block chain platform comprises 30 block chain link points, and the block chain platform divides 34 block chain link points into 5 common node groups. Then, there are 4 common node groups including 7 blockchain nodes, and there are 1 common node group including 6 blockchain nodes.
S203, the block chain platform sends grouping information to the N block chain nodes.
The grouping information is information indicating the M common node groups. The grouping information includes how many block chain link points each of the consensus node groups includes, and the identification of the block chain node included in each of the consensus node groups.
S204, the block chain platform receives M pieces of indication information sent by the M representative block chain nodes.
One representative block chain node is a block chain node in one common node group, and one piece of indication information is used for indicating a voting result of the representative block chain node on the target decision.
When the goal decision is voted, each consensus node group sends indication information to the blockchain platform through the representative blockchain nodes in the consensus node group. The indication information represents the opinion of the consensus node group where the block link point is located on the target decision, namely agreement or disagreement.
S205, the blockchain platform determines whether the N blockchain link points agree with each other according to the first information and the M indication information.
The first information includes: m representative block chain link points correspond to M calculated forces and M indicating information. One of the M calculated forces is the sum of the calculated forces P of all the block chain nodes in the consensus node group corresponding to the representative block chain node point.
And S2051, determining a first consensus result according to the first information.
If the first calculated power sum is larger than the second calculated power sum, determining that the first consensus result is: a consensus is achieved among the N block link points. And the first calculation power sum is the sum of K calculation powers corresponding to the K first voting results. The second calculation power sum is the sum of M-K calculation powers corresponding to the M-K second voting results. The K first voting results are results indicated by K pieces of indication information among the M pieces of indication information. The M-K second voting results are results indicated by the M-K indication information in the M indication information.
If the first calculated power sum is less than or equal to the second calculated power sum, determining that the first consensus result is: there is no consensus among the N block link points.
For example: after the block chain platform receives the M pieces of indication information, the block chain platform counts that the M pieces of indication information contain: the K pieces of indication information represent that the opinions of the K pieces of consensus node groups on the target decision are agreed, and the M-K pieces of indication information represent that the opinions of the M-K pieces of consensus node groups on the target decision are not agreed. And the computation power sums corresponding to the K consensus node groups for agreeing to the opinions are respectively as follows: q1, Q2, Q3 … … QK; the calculation power sum corresponding to M-K consensus node groups which cast disagreement respectively is as follows: r1, R2 and R3 … … RM-K. Then, the first calculated force sum is Q1+ Q2+ Q3+ … … + QK; the second force sum, R1+ R2+ R3+ … … + RM-K. When the first calculated force sum is larger than the second calculated force sum, determining that consensus is achieved among the N block link points; and when the first calculated force sum is less than or equal to the second calculated force sum, determining that the N block link points do not reach consensus.
And S2052, determining a second consensus result according to the M pieces of indication information.
If the number of the K first voting results is larger than the number of the M-K second voting results, determining that the second consensus result is: a consensus is achieved among the N block link points. The M-K second voting results are results indicated by the M-K indication information in the M indication information.
And if the number of the K first voting results is less than or equal to the number of the M-K second voting results, determining that the N block link points do not reach consensus.
For example: after the block chain platform receives the M pieces of indication information, the block chain platform counts that the M pieces of indication information contain: the K pieces of indication information represent that the opinions of the K pieces of consensus node groups on the target decision are agreed, and the M-K pieces of indication information represent that the opinions of the M-K pieces of consensus node groups on the target decision are not agreed. When K is greater than M-K, determining that consensus among the N block link points is achieved; and when K is less than or equal to M-K, determining that the N block link points do not reach consensus.
S2053, determining whether the N block link points achieve consensus according to the first consensus result and the second consensus result.
If the first consensus result is that consensus is achieved among the N block link points and the second consensus result is that consensus is achieved among the N block link points, then it is determined that consensus is achieved among the N block link points.
If the first consensus result is that the N block link points do not agree and/or the second consensus result is that the N block link points do not agree, then it is determined that the N block link points do not agree.
