Embodiment 1

[0071] In order to facilitate the description of the solution of this application, some relevant knowledge of the cold wallet is described here. Cold wallets usually include four parts: security media, common storage media, target applications (host computer software) and background servers. Among them, the security medium and the ordinary storage medium are set up in a secure electronic device, and the security medium is mainly used to store and calculate information with high confidentiality; while the ordinary storage medium is mainly used to transparently transmit the information transmitted by the upper computer, and hand it over to the security medium for processing. Processing (It should be noted that the communication between the host computer and the secure medium uses a secure encrypted channel, so no information is stored inside the ordinary medium). The target application program is set on the host computer (such as a user terminal and other devices) to interact wi...

Embodiment 2

[0106] Based on the first embodiment, this embodiment proposes a method for processing transaction information executed by a secure electronic device during a transaction. After the cold wallet is generated based on the cold wallet generation method provided in Embodiment 1, when performing a hidden transaction, the process can be referred to as follows Figure 4 shown, including:

[0107] S401: Obtain transaction information and the account address of the local end to be traded.

[0108] It should be noted that when using a cold wallet for transactions, after logging in to the APP corresponding to the cold wallet (i.e., the target application), the user needs to enter the transaction information in the target application and select the account address for the transaction on the local side (i.e. The account address of the local end to be traded), the target application is about to transmit the transaction information and the account address of the local end to be traded to th...

Embodiment 3

[0136] Based on the same inventive concept, the embodiment of the present application also provides a Zcash-based cold wallet generation device 100 and a transaction information processing device 200 . see Figure 7 and Figure 8 as shown, Figure 7 shown with figure 1 The methods shown correspond to the Zcash-based cold wallet generation device, Figure 8 shown with Figure 4 The shown method steps correspond one-to-one to the transaction information processing device. It should be understood that the specific functions of the device 100 and the device 200 may refer to the above description, and to avoid repetition, the detailed description is appropriately omitted here. The device 100 and the device 200 include at least one software function module that can be stored in a memory in the form of software or firmware or solidified in the operating system of the device 100 and the device 200 . specifically:

[0137] see Figure 7As shown, the device 100 includes: a first...

Abstract

The invention provides a cold wallet generation method and device, a transaction information processing method and device, electronic equipment and a readable storage medium. The cold wallet generation method comprises the steps of obtaining an assistant word with an actual expression meaning corresponding to a user, generating a parent seed file according to the assistant word, obtaining hidden transaction function keys of all levels according to the parent seed file, and generating an account address corresponding to a hidden transaction according to the hidden transaction function keys of all levels. Thus, the generated cold wallet has the account address specially used for hiding the transaction and the parent seed file capable of being used for generating the related function key of the hidden transaction, so that the cold wallet can complete the Zcash hidden transaction, and the problem that the existing cold wallet equipment does not support the complex hidden transaction is solved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular, relates to a method for generating a cold wallet, a method for processing transaction information, a device, a device, and a readable storage medium. Background technique [0002] At present, digital currencies such as Bitcoin generally use cold wallets to store digital currency, and because the key of the cold wallet is managed offline, only the signature result is provided during the transaction, and the risk of digital currency leakage is minimized. In addition, the cold wallet is easy to carry, and if it is lost, it can also be restored by restoring all information on other hardware, making the cold wallet a mainstream way of digital currency storage. [0003] Zcash is a digital currency that hides transaction information. According to Zcash related documents, there are currently two types of Zcash transactions, hidden transactions and transparent transactions....
