Description
Technical Field
The invention relates to the fields of block chains, data cochain, block chain application in the government affairs field and service data models, in particular to a method for defining a cochain data service protocol and an application service protocol of a block chain.
Background
The blockchain technology is a brand new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secures data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
Data uplink is to write data into a block chain, different block chains in the current market have different uplink modes, and for non-audit type block chains, basically, no matter who, whatever the content can be uplinked. Any transaction that occurs may be accompanied by text messages. The text content is not limited, only the size of the text affects the required cost. The mode has the advantages that signature verification and encryption and decryption basically do not exist in the uplink, the uplink protocol is not limited at all, and the risks of insufficient security and storage exist in a certain range.
For a specific type of blockchain, only specific types of data can be uplink, and the rest types of data cannot be uplink. Such as block chain invoices, transactions are invoiced, and invoices are reimbursed. The whole process is full-automatic without user's worry, and the whole link is linked up and can be checked. This approach limits the expansion of blockchain applications, and only one type of data can be uplink for a specific application, and multiple types of uplink data cannot be provided for the same application. It follows that the cost of changing the uplink data type is too high to meet the market demand when the service changes.
At present, the data uplink requirements of various industries are different, frequent changes can exist, such services are usually processed in an intelligent contract layer, an intelligent contract is a core thing, service risks and vulnerabilities can be brought by the frequent changes, and uplink requirements in different periods can change, so that historical data are compatible in the services.
Since the sector chain has many industrial applications, in the field of government affairs, the sector chain can model many industrial applications, such as an approval chain, a supervision chain, a certificate chain, a sharing chain and the like. In the chain application implementation process, each flow stage is complex, the situations of frequent business uplink data change, long approval process and more business data occur, the uplink data are difficult to adapt to business change quickly, and the most direct problem is that a project needs to be redeveloped, so that the business smoothness is affected, and the project cost is increased. There is a need for a flexible method of defining the uplink data service protocol to solve this problem.
