Detailed Description
So that the manner in which the above recited features of the present invention can be understood and readily understood, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings, wherein:
as shown in fig. 1, the method for controlling access to blockchain data for controlling the amount of assets management according to the present invention includes the following steps:
the first step is the setting of asset management limits. And setting an asset management quota value, and dividing the asset management quota value into N dimensionalities of quota values. In the idea of line management, according to different specific attributes, corresponding dimension division is performed to divide a total line into a plurality of sub-lines. For example, in managing the sales limit of the property or reservation limit, the sales limit is divided into three dimensions, which are sales organization, sales channel, and customer type, respectively.
And secondly, establishing the storage of the linked limit control block. And dividing corresponding N limit control blocks on the asset management block chain platform according to the division of the N-dimensional limit value. In order to match with the division of the credit management attribute, corresponding blocks are correspondingly divided on the block chain, and each block corresponds to credit control of one dimension. And generating blocks for the block chain data layer, and matching with the N-dimensional quota value in the application, realizing quota control based on the block chain technology. The method comprises the following specific steps:
(1) and respectively carrying out Hash encryption processing on the quota values of the N dimensions to generate N unique and irreversible characteristic values.
(2) And recording the hash encryption processing time, and stamping time stamps on the N characteristic values.
(3) And performing uplink processing on the corresponding timestamp and the characteristic value, and generating N limit control blocks on the asset management block chain platform.
Third, the credit control block is filled with credit values. Because the traditional credit control algorithm can increase the calculation amount of the block nodes, and the data layer of the block chain is also based on the design of a Merkle tree (binary tree), the credit value is constructed by the binary tree structure, a credit tree structure is established by using the binary tree mechanism in the credit control block, and the credit value in the credit control block is filled in the tree structure. The method comprises the following specific steps:
(1) and constructing a binary tree structure, wherein the root node of the binary tree is the credit value in the current credit control block.
(2) And setting the middle nodes of the binary tree as a plurality of sub-quota values forming quota values.
(3) Leaf nodes of the binary tree are set to be the quantum values constituting the quantum values.
(4) And filling the sub-quota value and the sub-quota value according to the quota value in the current quota control block.
Step four, transferring the amount under the chain: and respectively calling quota values from the N quota control blocks on the chain, and adjusting the tree structure in the quota control blocks according to the called quota values. The method comprises the following specific steps:
(1) obtaining the request for extracting the quota, analyzing the dimensionality to which the quota to be extracted belongs, and finding the quota control block corresponding to the dimensionality.
(2) Generating a quota calling command, wherein the quota calling command comprises the characteristic value of the corresponding quota control block and the quota value required to be called.
(3) The asset management block chain platform acquires the limit calling command, judges whether the characteristic value of the called limit control block is the same as the characteristic value of the limit calling command, and if not, rejects the limit calling command; if the same, the block security requirement is met, and the quota is retrieved in the quota control block.
(4) According to the credit value to be called, the credit value is configured in the binary tree structure of the credit control block, and the corresponding credit value is called out.
(5) And integrating the binary tree structure of the quota control block, and deleting the intermediate nodes or leaf nodes corresponding to the issued quota values.
In practical application, taking sales quota as an example, the quota value is set to be 100, which is divided into three dimensions of sales organization, sales channel and customer type, wherein the quota value of the sales channel dimension is 50. Firstly, establishing an quota control block with a quota value of 50 on a block chain platform, and then establishing a tree structure in the quota control block, wherein the root node of the tree structure is 50, the number of intermediate nodes can be designed to be 2, respectively 20 and 30, and the number of leaf nodes corresponding to the intermediate node of 20 can be four, respectively 5, 8 and 2. When the limit is called, the corresponding intermediate node and the corresponding leaf node are deleted, the limit control is realized, simultaneously, the block chain technology is utilized to display the limit control state and the change process on the chain, and all the operations are irreversible, so that the transparent disclosure of the limit control is realized.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
