Description
Technical Field
The invention relates to the technical field of block chains, in particular to a block chain consensus method.
Background
The consensus mechanism is a soul of a block chain, is a necessary means for a block chain network to achieve consistency in a decentralized environment, and the block chain develops from 2009 to the present, and various consensus mechanisms appear, each of which has advantages and disadvantages.
(1) Advantages of the current consensus mechanisms
A. Workload attestation mechanism POW
The nodes with the strongest computing power are blocked, so that the cost for doing malicious work can be effectively improved; the difficulty promotion strategy ensures that the probability that any plurality of blocks on the block chain are rewritten simultaneously through technical means is reduced to a minimum.
B. Equity certification mechanism POS
The competition blocking in the node with the maximum interest can avoid the waste of computing resources, the cost of doing the malicious work is directly related to the interest of the node with the maximum interest, and the probability of doing the malicious work is reduced to a certain extent by means of business.
C. Byzantine fault tolerance mechanism PBFT
All nodes in the network participate in voting, and the voting is less than (N-1)/3 nodes achieve agreement and block in reverse time synchronization.
Over time, the business is diversified and deep, and these consensus mechanisms with obvious advantages begin to have symptoms of inattention and show obvious defects in specific scenes.
(2) Problems with current consensus mechanisms
A. Wasted computing power
In the workload proving mechanism POW, only the nodes with the strongest computing power can be blocked, which results in a great deal of wasted computing power and prevents the general public from really participating in the consensus of the nodes.
B. Rights and interests are centralized to the top layer
In the equity proving mechanism POS, the probability of getting block qualification is higher for people with larger equity, and block means reward, which results in mutual promotion of 'getting reward and raising block probability' and 'getting greater equity by raising block probability', resulting in small equity nodes being marginalized and losing consensus participation right.
C. Low cost of doing malignant
In the accounting mode depending on the power and the rights, after the power and the rights are concentrated at the top level, the nodes in the top level set do harm to the nodes outside the top level set, and therefore, almost no cost exists; in the Byzantine fault tolerance mechanism, since all nodes can participate in consensus voting, the service attribute represented by the voting is weakened, and an unprivileged node has little penalty cost in the consensus process.
Therefore, for the sake of longer ecological block chain, it is more important to avoid the unburdened nodes, the high-rights group with low cost, and the above three common recognition mechanisms.
Disclosure of Invention

s1, when a new block is formed, the voter selects a high-quality node from all nodes as the voting representative to participate in block making after comprehensively considering the equity certification and the participation degree certification;
s2 voting represents block-making;
s3, screening out effective votes participating in block making, and determining corresponding voting nodes;
s4 distributing the reward generated by forming the block to the voting representative and the voter according to a distribution rule, wherein:
the voter refers to a node participating in the network activity of the block chain; the voting representatives are representative nodes which are selected by voters according to the rights and interests certification and the participation certification and represent the voters to participate in the block making, and the premise of participation certification is that the voters have participation through the participation acquisition.
Preferably, the equity certificate includes a direct equity certificate and an indirect composite equity certificate.
Preferably, the direct equity certificate includes the number of IBTs held by each node participating in the network activity, and the transaction amount of the node participating in the current round of activity.
Preferably, the transaction amount is the number of transactions that the voting representative will select from high to low to be packed into the new block according to the transaction commission and the transaction byte when generating the new block, and only the voting that the voting transaction is packed into the new block in the current round is effective voting.
Preferably, the indirect synthetic equity certificate includes a number of data transaction rings formed by the voter in conducting the network transaction.
Preferably, the allocation rule is such that 50% of the prize accrued by a new block is allocated directly to the voting representative of the production block, the remainder being allocated in terms of percentage of the interest of the participating voters.
Preferably, the participation degree obtaining mode includes providing high-reliability network performance to obtain the participation degree, obtaining the participation degree through providing terminal service, obtaining the participation degree through network activity, and obtaining the participation degree according to whether the transaction is completed fully, and the participation degree is increased along with the continuous superposition of the transaction by the node.
Preferably, the increase of the participation degree includes obtaining the service label name of the served node as the basis, and the 'self-participation' is based on the submitted effective transaction certificate.
Compared with the prior art, the invention has the following beneficial effects:
(1) the enthusiasm of participating users in voting is remarkably improved, and high-quality nodes can be selected to become voting representatives;
(2) by introducing the participation degree, different nodes in the network can be reasonably rewarded;
(3) the participation degree of each participating node in the activity on the network can be increased to a certain degree, so that participants with different dimensionalities can participate in the consensus and management of the network, and the defect caused by a single-dimensionality consensus mechanism is effectively avoided.
