Description
Technical field
The present invention relates to block chain technical field more particularly to block chain common recognition calculating fields.
Background technique
The common recognition mechanism of block chain, i.e., which miner obtains the encapsulation power of next block in decision block chain network, is
The core work mechanism of block chain is that block chain obtains decentralization feature, so that building has distributed security and data can
The key point of communication network.It is born from bit coin to current mainstream block chain network such as ether mill, with proof of work
(POW) as the core algorithm for obtaining common recognition.
POW knows together mechanism on the one hand due to a large amount of energy waste, keeps it more bigger stronger, right in today's society environmental consciousness
Under conditions of environmental requirement is higher and higher, it appears more and more outdated；On the other hand, random due to superelevation difficulty to be calculated
Number needs to take some time, so that the number of deals that accommodate its unit time can be severely limited, transaction effect
Rate is extremely low, the popularization and use this greatly limits block chain to large capacity, big concurrent application scenarios.
POS machine system is the Main way for solving the problems, such as that POW mechanism is existing at present, due to no longer needing to calculate random number,
Therefore can be realized simultaneously " green dig mine " (block encapsulation) and trading efficiency promoted, because due to by the great attention of industry and
Extensive concern.But the most POS machine systems or mechanism too complex that occur at present or one with existing block chain
A little core mechanisms, if the difference of block reward mechanism is excessive, so that it be made to be difficult to realize putting down from existing POW mechanism to POS machine
It slips over and crosses.
There are several critical issues to need to solve into the smooth transition of POS machine system realizing from existing POW mechanism:
(1) fair, reasonably select block encapsulation competition and obtain as based on how association attributes of existing user (miner)
Victor；
(2) how ensuring entire block chain when trading volume is big, network query function efficiency is able to satisfy the demand of high speed transaction, but
The newly-increased block of whole network will not be brought excessive because of too frequent block encapsulation again simultaneously, so that network be made integrally to motivate
It is excessive to issue additional miner's reward, brings the devaluation of network entirety reward points.
Summary of the invention
In view of this, the present invention devises a kind of high speed, the block chain POS common recognition calculation method of frequency conversion and system, pass through
This method and system can both possess the performance that the green that POS common recognition calculates digs mine, the transaction of high concurrent high efficiency is supported, can be with
It realizes smooth transition of the existing mainstream block chain technology from POW to POS, while guaranteeing network high-speed transaction, uses frequency conversion
The block of change encapsulates, and network entirety block packaging density is controlled in certain level.To achieve the above object, technology of the invention
Scheme is achieved in that
As shown in Figure 1, designing a kind of high speed, the block chain POS common recognition method of frequency conversion, include the following steps:
The first step, miner is based on its block chain account's weight, by block chain about fixed cycle periodically to block chain network
In digging pipe reason energy contract send miner's registering transaction；
Second step when new block generates, counts the random space size that the currently active registration miner is constituted, meter first
It is as follows to calculate formula:
RspaceFor current random space, M (i)balanceFor account's weight of i miner, miner's sum is registered as n；
Third step carries out Hash calculation, and by Hash calculation based on the cryptographic Hash of current block number and previous block
Byte data be converted to the random floating-point decimal r between 0~1float, rfloatDecimal place cannot be less than RspaceInteger-bit
Size；
The random space calculated by (2) is multiplied by the 4th step with the random number that (3) obtain:
RSelMiner=Rspace×rfloat (2)
R obtainedSelMinerThe miner M (j) corresponding to random space reflectionbalanceI.e. selected by the encapsulation of this block
In miner；
5th step, whether the miner that block encapsulation algorithm comparison (4) is chosen is this miner, if so, starting encapsulation region
Block；
6th step, block encapsulates the number of transaction in algorithm statistics trading pit, and calculates number of deals in trading pit and account for transaction
The ratio of pond top limit:
Trate=TPoolCount/Pmax (3)
7th step, block encapsulate time delay, control according to formula formula (4):
BMminmgDelay=TMaxDelay-TMaxDelav×Trate (4)
BminmgDelavTime delay, T are encapsulated for this blockMaxDelayTime delay is encapsulated for block maximum set by system；
8th step has encapsulated block to Web broadcast after block completes encapsulation；
9th step, remaining node receives encapsulated block after, by (2), (3), (4) step to block encapsulation miner carry out
Verifying, if meeting, is added main chain for block, if not meeting, abandons the block.
As shown in Figure 1, miner's registration about fixed cycle can be using the incrementss of the block number of block chain as calculation basis, such as
Arrange 100 blocks of every increase as a registration period or a set time such as one day and is used as a registration period.Using solid
Fixed cycle user's registration is the real-time online in order to ensure user, so that it is guaranteed that power is calculated in the block encapsulation of network.
As shown in Figure 1, block encapsulates the selection of current miner, it is important that the calculating of random number.Random number
Calculating, to guarantee two features simultaneously: (1) randomness, i.e. nobody can by calculate setting clearly set it is next
Whom miner is；(2) certainty, due to the consistency that whole network to be guaranteed calculates, any miner and block verifier can be with
According to current network data, identical current block encapsulation person is calculated according to determining mechanism.To realize the two features,
The present invention is using the cryptographic Hash of current block number and previous block number as data source, the side generated using Hash calculation as random number
Method.Hash calculation has the characteristics that following two: (1) determining that data source, cryptographic Hash calculated are determining；(2) data source is appointed
One minor change, cryptographic Hash becomes entirely different, and its variation is spatial stochastically distribution.
As shown in Fig. 2, common recognition computing system following module by being made of: (1) miner's weight statistical module；(2) random number
Generation module；；(3) miner's selecting module；(4) block encapsulates time-delay calculation module；(5) block package module；(6) encapsulation region
