Description
Technical Field
The invention relates to the field of block chain application, in particular to a method, a device and a system for storing bond distribution data based on a block chain.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
The bond is a valuable paper which is made by debtors of government, enterprise and bank, etc. to raise funds, issued according to legal procedure and committed to debtors to pay money on a specified date. After the completion of the purchase of the bond, if the purchase quantity exceeds the issue quantity, the bond is distributed according to a certain distribution algorithm (for example, dutch distribution). The amount of distribution of the bond is determined by the bond issuer, and the distribution result is calculated from the amount of the benefit of the bond sponsor (the underwriter or the direct investor) and the benefit rate of the benefit, and distributed to the bond sponsor.
In a traditional bond selling mode, a selling algorithm is realized in a business system of a bond issuer, a bond applying party cannot determine whether a selling result is distributed according to the selling algorithm advertised by the bond issuer, if the bond issuer manually changes the selling result, the selling amount of different bond applying parties is privately adjusted, unfairness of bond applying is caused, the selling willingness of some bond investors is reduced, and therefore the applying competitiveness of bonds is reduced, and the earning rate of the bond issuer is further reduced. In addition, since the distribution data is collectively stored in the business system of the bond issuer, if the business system of the bond issuer encounters a hacking attack, the distribution data is easily deleted or tampered, so that the data security is lowered.
In view of the above problems, no effective solution has been proposed.

and S101, acquiring procurement information of the target bond.
It should be noted that the target bond in the embodiment of the present invention may be any securities to be distributed, and the distribution is usually performed according to the subscription information of the bond subscription party (underwriter or direct investor). Optionally, the procurement information of the target bond acquired in S101 includes, but is not limited to: bond procurement amount, procurement interest rate and the like.
It should be noted that the method for storing bond distribution data based on a blockchain according to the embodiment of the present invention may be applied to a bond distribution system of an existing bond issuer, or may be used as a separate system to interface with the bond distribution system of the bond issuer to implement bond distribution data storage based on a blockchain. The acquired information on the target bond buying in S101 may be from a bond allotment system of the bond issuer (for example, the buying information on each bond buying party is entered by the staff of the bond issuer) or may be from a bond transaction management system of each bond buying party (the buying information on each bond is entered into each bond transaction management system by the staff of each bond buying party).
And S102, storing the procurement information of the target bond in the block chain system.
Because the bond allotment is usually determined according to the procurement information submitted by each bond procurement party, in order to ensure the equitable of allotment, after the target bond procurement is finished, the procurement information submitted by each bond procurement party needs to be ensured not to be changed, so the procurement information of the target bond is uploaded to the block chain system for storage after the procurement information submitted by each bond procurement party for the target bond is obtained. Since the data on the blockchain system is not tamperproof, the risk of tampering the procurement information can be prevented by storing the procurement information of the target bond in the blockchain system.
And S103, calling the intelligent contract of the block chain system, executing a distribution algorithm contained in the intelligent contract, and calculating to obtain a distribution result of the target bond according to the procurement information of the target bond.
The distribution result calculated in S103 includes at least: the calculated bond distribution amount distributed to each bond buying party according to the buying information of each bond buying party on the target bond).
As an alternative implementation manner, the allotment algorithm adopted in the embodiment of the present invention is "dutch allotment", that is, orders with low prosperity are preferentially allocated during the allotment, if the total amount of the currently distributed orders is greater than or equal to the total issued amount of the bond, the interest rate of the currently purchased orders is called marginal interest rate, and the orders on the marginal interest rate are to allot the remaining amount of the bond according to the percentage of the total amount of all the marginal interest rate orders occupied by the prosperity.
For example, a bond with an issue size of 1000 ten thousand is distributed in the manner of Dutch with purchase requisition and allotment amount as shown in Table 1.
