Once a malicious DAPP is encountered, it is susceptible to monetary losses. In the blockchain world, there are many phishing, or fraud, properties dapp (dapp: blockchain application, applet running on the blockchain). Many people are tricked each day because each account, each dapp in the blockchain, only a single address is shown to the people, e.g., 0x0c995d3e f521 e 8b ab05bf4a 19 b0509189998b,0x ef6d 0e 90738c458469c077416beec40f1a 9c 7a0e585e9497269755da, etc. People do not know what this address means at all, and if they are confirmed by a search engine or other channel, the process is cumbersome and can be easily omitted.
Generally, there are two ways people operate a blockchain: the first is a blockchain browser and the second is a blockchain wallet. The function of the browser is simple, and mainly looks at the blockchain information, such as a certain blockchain information (for example, a blockhash, a transaction contained in a block), transaction information, the number of blockchains in the whole block (i.e., the height of the block), and the like, which are all blockchain basic data. And typically only the viewing function, and not the money.
The functionality for blockchain wallets is complex, including the functionality to operate various DAPPs, including various blockchain social, gaming, investment applications, including transfer, or transfer-type DAPPs. Often involving money. Each DAPP, or payee, is a string of addresses that are easily confused by the user. Based on the above, almost every day people are phishing and fraud on blockchains. In addition, when the current blockchain wallet operates the DAPP, there is no suitable mechanism for reminding the user that the user needs to take responsibility and risk on his own, so it is necessary to design a mechanism for reminding the user of the risk when the blockchain DAPP is operated.

Detailed Description
The invention is described in more detail below with reference to the drawings and examples.
The invention discloses a blockchain wallet operation reminding method based on a blockchain intelligent contract, referring to fig. 1, comprising the following steps:
step S1, constructing a blockchain intelligent contract, wherein the blockchain intelligent contract comprises a blacklist and a whitelist for classifying DAPP addresses;
step S2, setting the blockchain intelligent contract to be in a state which can be read by the public;
step S3, the user accesses the DAPP address through the blockchain wallet;
step S4, judging the state of the DAPP address to be accessed according to the blockchain intelligent contract, if the DAPP address is positioned on a white list, executing step S5, and if the DAPP address is positioned on the black list, executing step S6;
step S5, allowing the user to access the DAPP address;
step S6, feeding back an obvious prompt message to the user so as to enable the user to select whether to continuously access the DAPP address, and if the user selects to continuously access, allowing the user to access the DAPP address; if the user selects to stop accessing, the operation of accessing the DAPP address is ended.
In the method, when the user accesses the DAPP address through the blockchain wallet, the DAPP address to be accessed is judged to be located on a white list or a black list according to the blockchain intelligent contract, and then corresponding reminding, selecting, allowing access or ending access steps are executed. Compared with the prior art, the invention judges the address based on the public transparent blockchain intelligent contract, can give out corresponding reminding and selecting functions when the user accesses the DAPP address, and greatly improves the safety and reliability of the user in the process of using the blockchain wallet.
For the way black and white gray lists are built in blockchain smartcontracts, please refer to the following two examples.
Embodiment one:
in this embodiment, a plurality of addresses are recorded in the blockchain intelligent contract, including corresponding black, white, and gray list states, and for the white list, a corresponding text description is also recorded. When the blockchain Qian Baoyun is in a line, address information judgment is automatically carried out from the intelligent contract, and a specific prompt is given to a user according to the judgment result, namely, the black-white gray list state.
There are two decision algorithms for making decisions based on smart contracts, one of which is optional:
mode one: in the step S1, the blacklist and the whitelist are obtained by manually inputting the DAPP address and voting the DAPP address.
In this manner, the intelligent contract offer voting system provides relevant personnel with address entry, and voting to determine white and black lists. If the address is not in the black-and-white list, the address can be regarded as a gray list, and the blockchain wallet program judges the state of the corresponding address according to the intelligent contract voting result.
Mode two: in the step S1, the blacklist and the whitelist are obtained after the designated administrator inputs the DAPP address.
In this way, an administrator setting system may be provided for the smart contract in advance, and the administrator may enter the black-and-white address list.
Example two
In another classification manner of the black-and-white list, in step S1 of the present embodiment, probability operation is performed according to DAPP information of the DAPP address, and then the black list and the white list are classified.
Further, the DAPP information includes, but is not limited to, DAPP deployment time, DAPP liveness, DAPP fund flow direction, and DAPP bytecode.
In the specific implementation process, firstly, the DAPP information is intelligently scanned, then the DAPP address information to be accessed is acquired by a wallet applet, and then risk judgment is carried out and the user is prompted.
Among the risk judgment factors include, but are not limited to:
the DAPP deployment time is used for judging whether the deployment is performed recently or not;
the activity of the DAPP is used for judging how many people interact by using the DAPP and judging whether operation and interaction exist after deployment;
the fund flow direction of the DAPP is used for judging whether the fund flow direction accords with the common malicious DAPP characteristics;
the byte code of the DAPP is used for judging whether the byte code accords with some common fraudulent DAPP byte code characteristics.
And combining the various data, judging the black-white gray probability, and reporting to a user in a proper mode so as to enable the user to decide whether to continue to access.
The blockchain smart contracts constructed based on the above two embodiments may be disclosed to the public with reference to the following:
in the step S2, the blockchain smart contract is set to a public read-only or public read-write state.
The method is characterized in that an intelligent contract external disclosure mode can be set to be readable, and the readable mode is obviously different from a conventional mode that a prior art center uses a private database mode to make a black-and-white list, and in the case, people can read the intelligent contract content, and the method belongs to a read-only condition.
However, with the expansion of application requirements, it may also be determined by the developer whether to use a public read-write mode, for example, in the embodiment of writing addresses and voting, if the voting link is performed by the developer's internal personnel and public personnel, this means that external personnel may also perform the writing operation. The invention is not particularly limited to the above-mentioned disclosed modes, and can be flexibly selected according to application requirements, and any mode is selected and belongs to the protection scope of the invention.
In practical applications, in the step S4, the DAPP address is classified as a gray list when the DAPP address is not on the white list or the black list.
Further, when the DAPP address is in the gray list, a prompt message is fed back to the user so that the user can select whether to continue to access the DAPP address, and if the user selects to continue to access, the user is allowed to access the DAPP address; if the user selects to stop accessing, the operation of accessing the DAPP address is ended.
In order to play a role in reminding the user, in step S5 of this embodiment, if the DAPP address is on the white list, a prompt message is fed back to the user, and then the user is allowed to access the DAPP address.
According to the specific situation of the DAPP address, in this embodiment, when the DAPP address is located on the white list, the gray list or the black list, the level of the prompt information fed back to the user and the obvious degree are gradually increased, so that the user can accurately distinguish the state of the DAPP address.
According to the blockchain wallet operation reminding method based on the blockchain intelligent contract, black and white gray list detection of the blockchain address is realized by the disclosed intelligent contract, and the black and white gray list detection function and the blockchain wallet are combined with each other, so that the safety and reliability of a user operation process are greatly improved, and the user needs and application requirements are better met.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of the present invention.
