Waste, therefore also by dirty disease.Everybody is more allowed to worry, once most of power of calculating is monopolized, decentralization is just on the hazard.
The second generation knows together mechanism POS, is exactly that equity proves common recognition mechanism, it is to be determined according to quantity with cash in hand with the time
Who possesses more billing rights.The advantages of this common recognition mechanism is can be to avoid energy consumption, but the disadvantage is that right of speech is all held
Coin rich and influential family is controlled, and centralized feature is formed, and also the original intention with block chain decentralization runs in the opposite direction.
Third generation common recognition mechanism is exactly DPOS, maximum feature, is exactly to be added on the basis that POS equity proves
Electoral system.The super node for the final acquisition billing right being born by all votes by ballot of user with cash in hand is kept accounts, can
To significantly reduce the waste of the energy, still, on the super node all concentrated due to operation, to the calculation force request of super node
It is higher, and the efficiency of super node directly affects the efficiency of book keeping operation, this is resulted in, this kind of mode copes with the ability of large-scale data
Not strong, development is restricted.

Random rule can be predefined in verifying common recognition mechanism.Preset first random rule can combine aforementioned shown in Fig. 2
Discussion in embodiment, details are not described herein again.
After the serial number for determining target verification node, can determine whether the serial number of the target verification node includes itself.
If including needing to execute step S360, if not including, terminating to verify process.
S360, if the serial number of current authentication node described in the serial number of the target verification node, to described first to
Verifying block is verified, and verification result is broadcasted in the block chain meshed network.
After above-mentioned two verification process all passes through, current authentication node needs to verify the first block to be verified,
And verification result is subjected to the whole network and is synchronized.Wherein, the verifying of block to be verified for first mainly verifies the book keeping operation of block node
Correctly whether, specific verification mode may include a variety of, and details are not described herein again.
