Description

A kind of block chain common recognition mechanism

Technical field

The present invention relates to block chain technical field, especially a kind of block chain common recognition mechanism.

Background technique

Common recognition mechanism is the soul of block chain, be block chain network reach under the distributed environment for going to center it is consistent must Standby means, block chain was developed so far from 2009 there are a variety of common recognition mechanism, they respectively have advantage and disadvantage.

(1) the advantages of current various common recognition mechanism

A, proof of work mechanism POW

By the strongest node block hitting of calculation power, cost of doing evil can effectively improve；Difficulty Promotion Strategy is by any on block chain Multiple blocks are dropped to very little by the probability that technological means is written over simultaneously.

B, equity proves mechanism POS

Compete block hitting in node by maximum equity, can to avoid the waste of computing resource, allow the cost done evil directly with Its equity is related, reduces the probability done evil to a certain degree with the means of business.

C, Byzantine failure tolerance mechanism PBFT

It participating in voting by nodes all in network, ballot is reached an agreement when opposing less than (N-1)/3 node and block hitting, this Kind mechanism is practical, high-efficient, the wasting of resources is few, and scalability is strong.

Over time, business is polynary deep, these have the common recognition mechanism of obvious advantage to start to occur power not From the symptom of the heart, and apparent disadvantage is shown under special scenes.

(2) the problem of current various common recognition mechanism

A, computing capability wastes

In proof of work mechanism POW, the only strongest node ability block hitting of computing capability is calculated which results in a large amount of The waste of ability, and ordinary populace can not really be participated in the common recognition of node.

B, equity is concentrated to top layer

Proved in mechanism POS in equity, the probability that the bigger people of equity obtains block hitting qualification is higher, and block hitting this means that Reward, this causes both " obtain reward and promote block hitting probability " and " improve block hitting probability and obtain bigger equity " to be mutually promoted, Cause small equity node by marginalisation and loses the participation right of common recognition.

C, do evil it is at low cost under

Node pair in the accounting mode by calculating power and equity, after calculating power and equity top layer is concentrated, in top layer collective Doing evil for top layer collective exterior node will be almost without cost；In Byzantine failure tolerance mechanism, since all nodes each may participate in altogether Know ballot, this will lead to the representative service attribute of its ballot and weakens, and one does not have interested node during this common recognition Almost without cost of doing evil.

Therefore, how the consideration more remote for block chain ecology avoids no equity node, Gao Quanyi collective from doing evil cost All kinds of problems that low and above-mentioned three kinds of common recognition mechanism occurs are more important.

Summary of the invention

The mechanism the present invention is directed to propose a kind of block chain is known together, in addition to effectively inheriting the service attribute of POS, the height of DPOS Outside the total involvement attribute for imitating attribute, PBFT, moreover it is possible to effectively no equity node and high equity collective be avoided to do evil at low cost ask Topic.

A kind of block chain common recognition mechanism, which is characterized in that the common recognition mechanism comprises the following processes step:

When a new block is formed, the voter is after comprehensive consideration equity proves S1 and participation proves from all High-quality node is selected in node as the proxy participates in block hitting；

S2 proxy carries out block hitting；

S3 filters out the effective ballot for participating in block hitting, determines corresponding ballot node；

S4 distributes to proxy and voter for reward caused by block is formed according to allocation rule, in which:

The voter, which refers to, participates in the movable node of block chain network；The proxy is by voter according to equity Proof, participation proof, which are elected, carrys out the representative node that vote by proxy people participates in block hitting, and the proof of the participation is on condition that logical The acquisition for crossing participation possesses participation.

It preferentially selects, the equity proves to include that direct equity proves to prove with comprehensive equity indirectly.

It preferentially selects, the direct equity proves to include the IBT number for participating in each node of network activity and being held Amount, node participate in the movable trading volume of epicycle.

It preferentially selects, the trading volume refers to that proxy can take and hand over according to transaction procedure when generating new block Easy byte selects the number of transaction that be bundled to new block from high to low, and only this ballot, which is traded, is packaged into the throwing of new block Ticket is only effective ballot.

It preferentially selects, the indirect comprehensive equity proves the data including voter's formation when carrying out network trading Transaction number of rings amount.

It preferentially selects, the allocation rule is to be distributed directly to production block for the 50% of the reward that new block generates Proxy, rest part distributes according to the equity percentage for participating in voter.

It preferentially selects, the participation acquisition modes include providing highly reliable network performance to obtain participation, lead to Offer terminal service is crossed to obtain participation, participation is obtained by network liveness, complete whether sufficiently obtain ginseng according to transaction With degree, with the continuous superposition of transaction, participation can increase node therewith.

Preferentially select, the increase of the participation include with get by the service labels of service node it is entitled according to According to, " from participate in " using effective transaction certificate of submission as foundation.

Scheme compared to existing technology, the invention has the following advantages:

(1) enthusiasm of participating user's ballot is significantly improved, being conducive to high-quality node can be selected in as proxy；

(2) prove that the different nodes in network can be rewarded reasonably by introducing participation；

(3) each participate in node on network activity can a degree of its participation of increase, can protect in this way The participant of card different dimensions each may participate in the common recognition and improvement of network, to effectively avoid single dimension common recognition mechanism bring Defect.
