Step 106, such as to generate the condition of i-th of chain of third block transaction be determining first data be trust data, when the first data are trust datas, handles certain things, example using first data It such as transfers the first data and does big data analysis, do various data analyses and extract, herein with no restrictions.

Such as first data be PM2.5 measured value, extract first data of (such as 1 week) in a period of time, multiple first data calculated according to the first data to calculate the PM2.5 concentration in this period, to obtain the air quality in this week.

Such as first data be industrial equipment instrument measurement data value,, first data in (such as 1 week) are extracted in a period of time, the measured data values more than thresholding 1 are obtained according to the first data, number and corresponding time by data, to judge instrument fault rate.

Such as first data be hospital sufferer case history, the first data are called in the case where the first data are trust datas by government organs or the third-party institution (reimbursement unit) or hospital, foreign side.

Such as i-th of Transaction Information are as follows: call the first data, Transaction Information specifically includes at least one of following: calling the user identifier of the first data, call the time of the first data, call the permission of the first data, the index value of first data, source (sender address) of the first data etc..

Generate the condition of i-th of transaction are as follows: when the trust data of the first data, call the first data.It calls the first data to can be used for carrying out big data analysis, can check first data etc..

Similarly, for j-th of Transaction Information of step 107 and similar.Such as jth transaction can be with are as follows: calls the first data.Jth Transaction Information can be central node and send error in data message to equipment 1.Therefore the condition of j-th of Transaction Information is generated are as follows: when the first data are trust data, call the first data；Or generate j-th of Transaction Information condition are as follows: when the first data be can not letter data when, central node send error in data message to equipment 1；

Certainly formed block chain Transaction Information, can be it is various, the application do not limit third block chain transaction content and form, the Transaction Information of third block chain, be not limited to be call the first data.By taking bit coin as an example, transaction is exactly that sender A gives recipient B a sum of money (such as 10 yuan).But inside Internet of Things, the movement that equipment executes is exactly a kind of Transaction Information, such as equipment A has sent an information to equipment B.Or calling the data of equipment A is exactly a kind of Transaction Information.
