The block chain network is added using the account and key in the first air monitering data record node, described in reception
The air monitering data packet in block chain network, the air monitering data packet include air monitering information, the air
The public key of the digital signature of monitor, the air monitor；
The first air monitering data record node calculates the air monitering information using SHA-256 function, raw
The digital signature of the air monitor is decrypted, is obtained using the public key of the air monitor at the first cryptographic Hash
Second cryptographic Hash；
The first air monitering data record node judges whether first cryptographic Hash and second cryptographic Hash are identical, such as
Fruit is identical, it is confirmed that the air monitering data packet is added to and is making by veritifying by the air monitering data packet
New block block body in, when the block body capacity reach 55MB when, using SHA-256 function to the block body institute
The air monitering data packet for including is calculated, and the cryptographic Hash of the new block is generated；
The first air monitering data record node is by the Kazakhstan of current time, the cryptographic Hash of previous block, the new block
Uncommon value storage is into the block head of the new block, using common recognition mechanism, the broadcast common recognition request in the block chain network, if
The common recognition request passes through, and obtains current time, current time is added in the block head of the new block, by the new district
Block is published in the block chain network.
