Description
Technical field
The present invention relates to block chain technical field, specifically a kind of block chain common recognition mechanism.
Background technique
Existing block chain common recognition mostly uses POW scheme (proof of work), and POW scheme is one satisfactory
Block Hash is made of N number of leading zero, and zero number depends on the difficulty value of network, and to obtain reasonable Block Hash needs
To attempt to calculate by a large amount of, calculate the Hash operation speed that the time depends on machine, when some node provide one rationally
Block hash value, illustrate the node really and have passed through it is a large amount of attempt to calculate, certainly, can not obtain the exhausted of calculation times
To value, because finding reasonable hash is a probability event.When node possesses the calculation power for accounting for the whole network n%, which has n/
100 probability finds Block Hash, and therefore, the calculation power of node is higher, and the probability for obtaining Block Hash is higher, in use
Block is concentrated to the high node of power is calculated out, leads to the presence of serious centralization in block chain network.
Due to the maximum block size limit of POW scheme 1MB in use process, the confirmation that each block has about 10 minutes is prolonged
(depend on average transaction size) late, maximum trading volume is only 7 times/second (TPS), and 7TPS is obviously unable to satisfy upper-layer service and needs
It asks；And huge energy consumption, such as: bit coin network consumes the electric power of about 25.5 gigawatts (GW) every year at present, entire Hibernian
Electricity consumption is only 3.1 gigawatts, and Austrian electricity consumption is 8.2 gigawatts, and the electric energy of bit coin network consumption is considerably beyond small-sized state
The whole electricity consumption of family, and in the past year, too kilowatt hour (TWH) number of bit coin network consumption increases 413.37%.Therefore
Improve transaction rate, the saving energy becomes block chain network and has to solve the problems, such as.
Summary of the invention
The object of the present invention is to provide a kind of block chain common recognition mechanism, can solve miner's centralization problem in block chain.
In order to achieve the above object, the mechanism the present invention adopts the following technical scheme: a kind of block chain is known together, including block chain
Public chain, block chain public affairs chain are equipped with miner and verifying node, and miner is the node for participating in out block registered in block chain public affairs chain, is tested
Miner after demonstrate,proving nodes records registration, verifying node are verified node by calculating and are generated miner's volume with queue format management miner
Number.
Preferably, verifying node is selected next miner by stochastic selection algorithm and is numbered.
Preferably, the stochastic selection algorithm realizes that process is as follows:
Miner's sum in block chain public affairs chain is obtained, the value of miner's sum is m, and m is the positive integer that minimum is 16；
Newest block number is obtained, newest block number is n, and n is the integer that minimum is 0；
The random character in the cryptographic Hash character string of newest block is obtained as modulus, when the random character is 0, to be taken word
As modulus after symbol plus 1, the modulus is mod；；
Miner's range is c, is obtained by block number n and modulus calculation mod；
Miner's range boundary is s, is obtained by miner's sum m and modulus calculation mod；
The last one range mathematics of miner is r；It is calculated and is obtained by new district block number n and miner's range boundary s；

Preferably, the block chain common recognition mechanism is applied in block chain network.
Compared with prior art, the present invention has the following advantages and beneficial effects: selecting one by chance mechanism proof
A node solves the problems, such as miner's centralization in block chain；Calculation method is simple, improves out block efficiency；And when calculating
Between it is short, resource consumption is few；It is random to generate miner's number, DDOS attack difficulty height is improved, internet security is enhanced.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of block chain common recognition system provided by the invention.
Specific embodiment
The technical scheme of the present invention will be explained in further detail below.
A kind of block chain common recognition mechanism, including block chain public affairs chain, block chain public affairs chain are equipped with miner and verifying node, miner
For the node for participating in out block registered in block chain public affairs chain, the miner after nodes records are registered is verified, verifies node with queue shape
Formula manages miner, and verifying node generates miner's number by calculating.
A kind of block chain common recognition mechanism provided by the invention, as shown in Figure 1, specific as follows:
Step 1, the validity for verifying new block.
Interdependent node information, verifying node audit section are inputted by verifying node in the node that block chain public affairs chain participates in out block
Point information passes through verifying after passing through, and the Node registry for participating in out block is new miner.
Step 2, management miner.
Nodes records miner is verified, and is queued up miner by registration sequencing.
Step 3 selects miner's number by stochastic selection algorithm.
Miner's sum in block chain public affairs chain is obtained, the value of miner's sum is m, and m is the positive integer that minimum is 16；
Newest block number is obtained, newest block number is n, and n is the integer that minimum is 0；
