Unit.
In order to make it easy to understand, first to the present embodiments relate to carry out a simple introduction to some concepts arrived.
Block chain technology is that algorithm of knowing together with storing data, using distributed node is verified using block linked data structure
Guarantee the safety of data transmission and access with more new data, in the way of cryptography, using by automatized script generation to generate
The intelligent contract of code composition programs the completely new distributed basis framework and calculation paradigm of one kind with operation data.It is simple next
It says, in block catenary system, per after a period of time, each transaction data for participating in main body generation can be packaged into a data field
Block, data block are arranged successively sequentially in time, form the chain of data block, and each main body that participates in possesses same data-link
Item, and can not unilaterally distort, main body agreement of the modification of any information only by about certainty ratio can carry out, and can only
New information is added, old information can not be deleted or modified, thus information sharing and consistent decision between realizing multiagent, it is ensured that
Transaction Information can not distort, is open and clear between each subject identity and main body.
Each information is owned by oneself distinctive block chain " identity card ", and every information all has the number of each main body
Signature and write time stamp, for consumer query and verification.The data signature and encryption technology of block chain make full link information real
Anti-tamper, standard unification and high efficiency exchange are showed.
A kind of inventory records method based on block chain is proposed in embodiments of the present invention, is applied to block chain commodity and is remembered
On recording system, the block chain inventory records system that the embodiment of the present invention is applicable in includes first node, first node, block chain private
