The first embodiment is as follows:
a data management method for a double-ended blockchain, see fig. 1, includes the following steps:
s1: when the network transaction data is stored in the block chain, a first block header is generated according to a previous block and the network transaction data, and a second block header is generated according to the previous block, which specifically includes:
and combining the first block head in the previous block, the network transaction data and the current timestamp, performing hash operation on the combined numerical value, and taking the operation result as the first block head.
And combining the first block head in the last block and the current timestamp, performing hash operation on the combined numerical value, and taking the operation result as the second block head.
Specifically, when the blockchain generates a block, a first block header is generated according to the network transaction data, the previous block data and the timestamp which are required to be stored, and a second block header is generated according to the previous block data and the timestamp, so that a completely different first block header and a completely different second block header are obtained. For example: when the block chain generates the third block, H3 is calculated to be (H2+ network transaction data + timestamp) to perform a hahs operation, and H3 is calculated to be (H2+ timestamp) to perform a hahs operation, where H3 is a first block header of the third block, H3 is a second block header of the third block, and H2 is a first block header of the second block.
S2: generating a block connected after the last block on the block chain, wherein in the generated block, a block head comprises the first block head and a second block head, 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 headers, and network transaction data is stored in the block.
S3: when receiving a query instruction of a user, analyzing the query instruction, and reading data of the block body in the block according to an analysis result, specifically comprising:
when a query instruction of a user is received, analyzing the query instruction to obtain an analysis result;
if the analysis result is matched with the first block head of one block in the block chain, reading the data of the block in the block as output data;
if the analysis result matches the second block head of a block in the block chain, the output data is null.
Specifically, when querying the network transaction data in the blockchain, if the user wants to read the network transaction data stored in a certain block, the user sends a query command including a first block header in the block. If the network transaction data stored in a certain block is not to be read, a query command containing a second block header in the block is sent. Thus, when the first block header 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 null.
In the method, each block on the block chain comprises two block heads, wherein the first block head is associated with network transaction data, and the second block head is not associated with the network transaction data, so that a user can select whether to read the network transaction data in the block according to the requirement of the user, and the function of monitoring the network transaction information on the block chain is realized.

a data management system for a double-ended blockchain, see fig. 3, comprising:
a storage unit: when the network transaction data is stored in the block chain, generating a first block head according to a previous block and the network transaction data, and generating a second block head according to the previous block; generating a block connected after the last block on the block chain, wherein in the generated block, a block head comprises the first block head and a second block head, and a block body comprises the network transaction data;
a query unit: and the data processing module is used for analyzing the query instruction when receiving the query instruction of the user and reading the data of the block body in the block according to the analysis result.
Preferably, the storage unit is specifically configured to:
and combining the first block head in the previous block, the network transaction data and the current timestamp, performing hash operation on the combined numerical value, and taking the operation result as the first block head.
Preferably, the storage unit is specifically configured to:

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