The scheme realizes the batch casting of the NFT method by improving the original NFT protocol, saves a large amount of gas consumption and time consumed by frequently calling contracts for users, greatly reduces the required transaction number, and has a certain improvement effect on the congestion problem of the ether workshop. The administrator can convert the vacation of the employee into a vacation NFT permit, each vacation of the employee corresponds to one vacation NFT permit, each vacation NFT permit has a unique identifier and an owner, through the conversion, the administrator is convenient for the vacation management of the user, and the possible confusion condition in the vacation management process is reduced. The introduction of the intelligent contract also enables the vacation management to be more transparent, and the staff can also quantify the gains brought by overtime, so that the transparency of the vacation management system is improved.
On the basis, the invention can realize the following technical effects:
in this embodiment, as shown in fig. 2, the method includes a user management stage, a vacation certification stage, and a vacation certification use stage. The improvement of the NFT protocol is completed in a vacation certification stage, the original NFT protocol does not stipulate the NFT casting mode, and most NFT implementation modes on the market only can cast one NFT at a time for safety consideration, so that the time efficiency is low, and gas consumption is high. The invention improves the NFT protocol by realizing batch casting of NFT, and can realize casting of a plurality of NFTs by one contract call, and the identifier and the owner of each NFT are unique, and the data structure is the same as the original NFT protocol.
In this embodiment, as shown in fig. 2, the improvement of the NFT protocol of the present invention exists in the vacation certification phase, and the pseudo code of the improved NFT protocol is shown in fig. 7;
referring to FIG. 7, to is the address identifier of the user, and amount is the number of cast NFTs, and three internal variables of the intelligent contract are used: vacationBalanes, vacationOwners, and vacationCounter. Wherein, vacationBalances represents the vacation balance of the user and is a key value pair from address to integer; vacationOwners represents the owner of the vacation NFT certificate, and is a key-value pair from integer to address; the vacationCounter represents the identifier of the vacation NFT pass, i.e., the id of the NFT, and is an integer variable. The address in the variables is a special variable in the Etherhouse intelligent contract and represents an account, namely the unique ID of the user.
Through the pseudo code thought of fig. 7, the invention realizes the batch casting of NFTs, that is, casting of multiple NFTs can be realized through one-time calling of a contract function, and in a vacation management scenario, the NFTs are converted into a certification which can help users to cast vacation NFTs in batches. The data structure of each vacation NFT certificate is the same as that of a common NFT, the balance of an owner and a user of the NFT is recorded through two key value pairs of owner and balance, and the NFT batch casting method is realized by introducing a third variable vacationCounter. The contract built-in variable vacatecounter is a unique identifier of a vacation NFT pass, the identifier is increased by 1 each time the vacation NFT pass is generated, and the variable is a private variable, and a user can only change the value of the vacatecounter by calling a mintBatchVacations function and cannot directly modify the variable, so that the user cannot repeatedly cast the vacation NFT pass with the same identifier, and the safety of the contract is guaranteed.
The gas consumption and the transaction number of the vacation general certification system and method based on the improved block chain NFT protocol provided by the present invention are further described in the following two specific experimental examples.
(1) gas consumption
In the ether house, gas consumption can be understood as the overhead incurred by miners to validate and chain transactions, since chaining requires some overhead as the state of the blockchain needs to be modified. The user's interaction with the intelligent contract may also be viewed as a transaction from the user to the intelligent contract with additional data, i.e., the function to be called and its required parameters. Each intelligent contract has its own storage space and stores variables related to the contract, so that the functions in the contract are divided into two types, one is a function which consumes gas, and the other is a function which does not consume gas. The function consuming gas modifies the built-in variable in the contract, while the function not consuming gas only queries the built-in variable of the contract and does not modify the built-in variable. Therefore, the gas consumption is a key index for measuring the efficiency of the intelligent contract, the lower the gas consumption is, the less the overhead is generated, the number of operations executed in the intelligent contract is reduced, and the efficiency is higher as a whole.
In this embodiment, as shown in fig. 5, a gas consumption comparison between the improved NFT protocol of the present invention and the original NFT protocol is shown. It can be seen from the figure that the consumption of gas is much less than that of the original NFT protocol in the case of a larger number of NFTs to be cast by the batch NFT casting method of the present invention. It can also be seen from this figure that both gas consumption curves are straight lines, i.e., the gas consumption is linearly related to the number of cast NFTs.
The gas consumption of the original NFT protocol is in a linear relationship with the number of the cast NFTs, because only one NFT can be cast at a time in consideration of safety and practical application scenarios, and because the gas consumption of the NFT can be fixed in each time of casting the NFT, that is, calling the casting function in the smart contract, when a plurality of NFTs are to be cast, the casting function in the contract can be called only for a plurality of times, so that the final gas consumption and the number of the cast NFTs are in a linear relationship.
The gas consumption of the improved NFT protocol is linearly related to the number of the cast NFTs because in the improved NFT protocol, the batch casting NFT method is essentially implemented by a loop, and the termination condition of the control loop is the incoming parameter amount, i.e. the number of the cast NFTs, so that the loop will be done more than once every time the number of the cast NFTs is increased by one, and the statement to be executed in each loop is fixed, and the gas consumption thereof is also fixed, so that the final gas consumption and the number of the cast NFTs are linearly related. In consideration of application scenarios, in a vacation management scenario, NFT is cast in batch, that is, a user's vacation is converted into a vacation NFT general certificate in batch, each vacation corresponds to a vacation NFT general certificate, which is of practical significance, and the employee's vacation often has more than one day, and if the number of vacation days is large, gas consumption is greatly reduced compared with the original NFT protocol.
(2) Number of transactions
In the etherhouses, transactions are roughly divided into two types, one is a transaction between a user and a user, and the other is a transaction between a user and an intelligent contract. There are also two functions in a smart contract, one that will consume gas and the other that will not. If the user interacts with a function consuming gas in the intelligent contract, a transaction is generated each time the function is called; if a user interacts with a function that does not consume gas in the smart contract, no transaction is generated regardless of how the function is invoked.
In an etherhouse, a transaction requires a certain time from release to uplink, which depends on the total number of transactions and the speed of out-blocking within the same time. If the number of the transactions submitted to the whole network in the same time is small and the speed of the block output is high, the confirmation time of the transactions is relatively short, and on the contrary, the confirmation time of the transactions is relatively long. The ether house has a congestion problem nowadays, that is, the number of transactions in the whole network is too large, the speed of the outgoing block cannot catch up with the speed of the transaction generation, so that the acknowledgement time for a transaction to wait is very long, and if the user does not set a higher gas, the user may need to wait for several hours before the transaction is linked up.
In this embodiment, as shown in fig. 6, a comparison between the number of transactions of the improved NFT protocol and the original NFT protocol is shown. As can be seen from the figure, the original NFT protocol produces a new transaction for each NFT cast, while the modified NFT protocol can cast multiple NFTs in one transaction. Therefore, in the improved NFT protocol, no matter how many NFTs are cast, only one transaction is generated as long as the upper limit of gas set by the transaction is not exceeded; whereas in the original NFT protocol, one transaction is generated at a time when an NFT is cast, the number of transactions to improve the NFT protocol is much smaller than that of the original NFT protocol in terms of the number of transactions. Each transaction needs a certain time from sending to uplink, so that a plurality of NFTs can be cast by one transaction, thereby saving a great deal of waiting time for users; moreover, the number of interactions with the intelligent contracts is reduced, the number of transactions is also reduced, and the improvement can provide a certain relieving effect on the current congestion problem of the Ethermen.
The above embodiments only express specific embodiments of the present application, and the description is specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which all belong to the protection scope of the present application.
