Embodiment one:
a method of data management for a dual-headed blockchain, see fig. 1, comprising the steps of:
s1: when the network transaction data is stored in the blockchain, generating a first block header according to the last block and the network transaction data, and generating a second block header according to the last block, specifically comprising:
and combining the first block head in the previous block, the network transaction data and the current timestamp, carrying out hash operation on the combined value, and taking the operation result as the first block head.
And combining the first block head in the previous block with the current timestamp, carrying out hash operation on the combined value, and taking the operation result as the second block head.
Specifically, when generating a block, the blockchain generates a first block header according to network transaction data, last block data and a time stamp which are stored as required, and generates a second block header according to the last block data and the time stamp, so that completely different first block header and second block header are obtained. For example: when the block chain generates the third block, h3= (h2+network transaction data+timestamp) is calculated to perform hahs operation, h3= (h2+timestamp) is calculated to perform hahs operation, wherein H3 is the first block header of the third block, H3 is the second block header in the third block, and H2 is the first block header of the second block.
S2: generating a block connected after the last block on a block chain, wherein in the generated block, a block header comprises the first block header and the second block header, and a block body comprises the network transaction data;
specifically, the blockchain generated by the method is shown in fig. 2, each block in the generated blockchain has two block heads, and network transaction data is stored in the block.
S3: when a query instruction of a user is received, the query instruction is analyzed, and the data of the block in the block is read according to the analysis result, specifically including:
when a query instruction of a user is received, the query instruction is analyzed, and an analysis result is obtained;
if the analysis result is matched with the first block head of a block in the block chain, reading the data of the block in the block as output data;
if the parsing result matches the second block header of a block in the blockchain, the output data is null.
Specifically, when a user queries the network transaction data on the blockchain, if the user wants to read the network transaction data stored on a block, the user sends a query instruction containing the first block header in the block. If the network transaction data stored on a block is not wanted to be read, a query instruction containing the second block header in the block is sent. Thus, when the first block head of a certain block is analyzed, the data of the block in the block is read. When the second block head of a certain block is analyzed, the data of the block in the block is not read, and the output data is empty.
In the method, each block on the block chain comprises two block heads, wherein the first block head is related to the network transaction data, and the second block head is not related to the network transaction data, so that a user can select whether to read the network transaction data in the block according to own requirements, and the function of supervising the network transaction information on the block chain is realized.

if the analysis result is matched with the first block head of a block in the block chain, reading the data of the block in the block as output data;
if the parsing result matches the second block header of a block in the blockchain, the output data is null.
In the system, each block on the block chain comprises two block heads, wherein the first block head is related to the network transaction data, and the second block head is not related to the network transaction data, so that a user can select whether to read the network transaction data in the block according to own requirements, and the function of supervising the network transaction information on the block chain is realized.
