Background technique
Block chain technology (Blockchain technology, abbreviation BT), is also referred to as distributed account book technology, is
A kind of internet database technology, its main feature is that it is decentralization, open and clear, allow everyone to each may participate in data-base recording.Most
It is early the basic technology of bit coin, is studying all over the world at present, can be widely applied to each field such as finance.The base of block chain
This concept includes: (1) transaction (Transaction): once-through operation leads to the primary change of account book state, such as one note of addition
Record；(2) data block (Block): the transaction and state outcome occurred in record a period of time, is to the primary of current account book state
Common recognition；(3) it chain (Chain): is connected in series by block one by one according to order of occurrence, is the log recording of entire state change.
Original block chain technology, each data block can not just change again after generation, because of subsequent data
Block can record the cryptographic Hash (hash) of current data block.If any one byte (bit) of change, can all lead to it
Hash value changes, and such change can be refused by whole network.The not alterability of original block chain technology is to block
Chain brings public credibility.But under many scenes, the not alterability of block chain brings many troubles to application, causes
The application range of block chain is extremely restricted.For this purpose, existing propose some block chain modification technologies.
Currently, block chain modifies technology, mainly include the following types: 1) carrying out bifurcated, such as ether mill network to block chain
Become two chains after bifurcated.2) data field that part is stayed in data block, is not involved in checked operation.
However, in the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:
The method of bifurcated just will appear only in extreme situations (such as when recovering stolen digital asset).In number
According to the data field for staying part on block, it is not involved in checked operation, but the data of these data fields for being not involved in checked operation, Ke Nengjing
Often changed to change, is unable to control.
