Shield.System be it is open, in addition to the private information of Trading parties be encrypted other than, the data of block chain disclose owner, any
People can pass through disclosed interface polls block chain data and exploitation related application, therefore whole system information highly transparent.
Block chain, which is used, makes the institute in whole system based on consensus specification and agreement (such as a set of open and clear algorithm)
There is node can be in the exchange data for going the free safety of the environment trusted, so that the trust to " people " has been changed to the letter to machine
Appoint, any artificial intervention does not work.Once information is by verifying and is added to block chain, permanent will store,
Unless can control simultaneously be more than in system 51% node, be otherwise to the modification of database on individual node it is invalid,
Therefore the data stability and reliability of block chain are high.Since the exchange between node follows fixed algorithm, data are handed over
It is mutually to be not necessarily to trust (rules of order in block chain can voluntarily judge whether activity is effective), therefore counterparty need not pass through
The mode of public identity allows other side to oneself generation trust, very helpful to the accumulation of credit.
Block chain as future generation computer system, the practical problem urgently handled in practical application there are also it is many not
It is proposed specific solution.
