Before the specific technical solution according to present disclosure is discussed in detail, present disclosure institute base will be introduced first
In the technical issues of, such as the big file of a 10kb, if necessary to carry out storing on chain to it, then pushing away with the time
It moves, more and more big files will be all stored on block chain, then data will be drastically swollen on the chain of entire block chain
Swollen, it is excessive to eventually lead to overabundance of data on the chain of block chain, to be unfavorable for the operation of block chain network；On the other hand, if
The data are only carried out to store under chain, then the data there is a possibility that be tampered, and data safety cannot be guaranteed.
In addition, block chain uses distributed storage pattern, to the storage of data, there are probelem in two aspects at present.
The problem of first aspect, is that reading and writing size of data is limited.Specifically, block chain have to uplink data it is stringent
Size limits, and not can be well solved big file storage.
The problem of second aspect, is that memory capacity is difficult to estimate.Specifically, each node can get on block chain
The data that full chain is submitted, safeguard full dose data backup.Over time, the data volume that node is preserved will be with uncontrollable
Mode increases.
Big file is stored, data preservation is a kind of normal method under chain at present.However, there is no one kind to be directed at present
Storage solution under the systematization of file, standardized chain cochain greatly.That is under the chain being previously mentioned in the prior art
There is no the flows of systematization for data storage.To the processing of big file at present still based on storage location under chain, do not carry out
Information processing on chain, the prior art are not prescribed by under chain with how data on chain are associated, and how to judge that data are answered on chain also
It is to be stored under chain, and how the data stored under this chain cochain are read out.
In order to solve the above-mentioned technical problem, the design of present disclosure is as follows, i.e., the disclosure proposes a kind of for block chain
Chain cochain under data processing method, to solve the problems, such as that the size of data on the chain for reading or being written is restricted.Together
When this is used for data processing method under the chain cochain of block chain and can control uplink data amount, held with alleviating the storage of block chain node
Amount increases too fast pressure.
Specifically, storage rule intelligence contract can be defined under the chain cochain in data processing method, to limit cochain number
According to rule and uplink data format；In addition, when executing block chain write operation, whether data are judged according to pre-defined rule
Directly store to block chain.In the case where data are not stored directly on block chain, according to storage rule intelligence contract come really
Surely the format of the metadata to the uplink data on block chain is stored.At the same time, data also may include data on chain under chain
Relevant information, such as block chain nodal information, cochain time etc..Data can guarantee tamper-resistant and data integrity, while chain on chain
The presence of lower data also can effectively control the scale of uplink data.
Correspond ground, when executing block chain read operation, can support to read simultaneously on chain with chain under data.It is optional
Ground, write operation interface can further support data compression or batch data to submit, to be further reduced uplink data amount.
