Abstract
The invention discloses a method for pre-locking Token by adopting an intelligent contract, which comprises the following steps: acquiring user signature data generated by signing the Token locking number by a user; performing secondary signature on the user signature data by using a server address, and generating server signature data; and calling an intelligent contract to verify the user signature data and the server side signature data, and if the verification is passed, pre-locking the number of tokens to be locked by the user in the server side address by using the intelligent contract, so that the sum of the number of tokens used by the user in the server side address does not need to interact with the block chain in a locking range. The invention effectively solves the problem of token state competition, and can reduce the time cost and the execution cost of transactions caused by frequent interaction with a block chain.
Description
Technical Field
The invention relates to the technical field of computers, in particular to a method for pre-locking Token by adopting an intelligent contract.
Background
When the user operates the Token in the address, the user needs to directly call the intelligent contractor to operate the Token. However, this causes the following problems:
1. there is a problem of Token state competition. The malicious user can send a payment request to the server and send a transaction with higher commission to the intelligent contract at the same time, so that the payment request received by the server is behind a second transaction with higher commission, and the transaction cannot be successfully executed normally;
2. each time the intelligent contract is called, the transaction (transaction) needs to be confirmed by a block chain, the waiting time depends on the congestion degree of the transaction on the chain and the set handling fee, and the transaction cannot be accurately evaluated;
3. gas is consumed for calling the intelligent contract every time, and frequent calling is high in cost.
To this end, the applicant has sought, through useful research and research, a solution to the above-mentioned problems, in the context of which the technical solutions to be described below have been made.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: aiming at the defects of the prior art, a method for pre-locking Token by adopting an intelligent contract is provided to solve the problem of state competition in the Token using process and reduce the time cost and the execution cost of transaction caused by frequent interaction with a block chain.
The technical problem to be solved by the invention can be realized by adopting the following technical scheme:
a method for pre-locking a Token with an intelligent contract, comprising the steps of:
acquiring user signature data generated by signing the Token locking number by a user;
performing secondary signature on the user signature data by using a server address, and generating server signature data;
and calling an intelligent contract to verify the user signature data and the server side signature data, and if the verification is passed, pre-locking the number of tokens to be locked by the user in the server side address by using the intelligent contract, so that the sum of the number of tokens used by the user in the server side address does not need to interact with the block chain in a locking range.
In a preferred embodiment of the present invention, after the user signature data is acquired, the acquired user signature data is verified to confirm whether the Token number in the account corresponding to the user allows performing the pre-locking operation.
In a preferred embodiment of the present invention, the user signature data is generated by a user signing the Token lock number and a random number, and when the user signature data is verified by invoking an intelligent contract, it is required to confirm whether the random number in the user signature data already exists; if so, the pre-lock operation is not allowed to prevent replay attacks.
Due to the adoption of the technical scheme, the invention has the beneficial effects that: the invention signs through the Token locking quantity and entrusts the server to call the intelligent contract, after the transaction is successfully executed, the sum of the Token quantity used by the user at the server no longer needs to interact with the block chain in the locking range, and no additional commission charge is generated. Therefore, the token state competition problem is effectively solved, and the time cost and the execution cost of transaction caused by frequent interaction with the block chain can be reduced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a flow chart of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Referring to fig. 1, a method for pre-locking a Token with an intelligent contract is shown, comprising the steps of:
step S10, user signature data is acquired, and the user signature data is generated by signing the Token lock number and a random number by the user.
Step S20, carrying out secondary signature on the user signature data by using the server address, and generating server signature data;
step S30, calling an intelligent contract to verify the user signature data and the server signature data, on one hand, confirming whether a verification transaction sender is the server address, on the other hand, confirming whether the user signature and the number of tokens to be operated correspond to each other and whether the random number exists, if the verification transaction sender is the server address, and the user signature and the number of tokens to be operated correspond to each other and the random number does not exist, pre-locking the number of tokens to be locked by the user in the server address by using the intelligent contract, so that the sum of the number of tokens used by the user in the server address does not need to interact with a block chain in a locking range, and no additional handling charge is generated. When the user selects unlocking, settlement is carried out according to the using quantity, and the rest part of the intelligent contract is unlocked by calling, so that the problem of token state competition is effectively solved, and meanwhile, the time cost and the execution cost of transaction caused by frequent interaction with the block chain can be reduced.
In step S10, after acquiring the user signature data, verifying the acquired user signature data to determine whether the number of tokens in the account corresponding to the user allows execution of the pre-locking operation; if execution of the preliminary lock operation is permitted, the process proceeds to step S20.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
