Embodiment 1

[0029] According to this embodiment, a method embodiment of a data processing method applied to a block chain node is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in such as a set of computer-executable instructions computer system, and although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0030] The method embodiments provided in this embodiment can be executed in computer terminals, servers or similar computing devices. figure 1 A block diagram of a hardware structure of a computing device for implementing a data processing method applied to a blockchain node is shown. Such as figure 1 As shown, the computing device may include one or more processors (processors may include but not limited to processing devices such as microprocessors MCUs or programmable logic devices FPGAs), memo...

Embodiment 2

[0074] Figure 6 It shows that the data processing device 600 applied to a blockchain node according to the first aspect of this embodiment is applied to a first node of a first blockchain. The device 600 corresponds to the method according to the first aspect of the first embodiment. refer to Figure 6 As shown, the device 600 includes: a data receiving module 610 for receiving data from the second block chain; a first encryption module 620 for encrypting data to generate encrypted encrypted data; a second encryption module 630 , for encrypting the key used to decrypt the encrypted data with the public key of the node user of the second blockchain, thereby generating encrypted key information; and a block generation module 640, for using the encrypted data as the block block body and use the encrypted key information as a block header to generate a block corresponding to the received data. .

[0075] Optionally, the first encryption module includes: a user list query subm...

Embodiment 3

[0080] Figure 8 Shows the data processing device 800 applied to blockchain nodes according to the first aspect of this embodiment, used for the first node of the first blockchain, the device 800 is the same as the first node according to Embodiment 1 Corresponding to the method described in this aspect. refer to Figure 8 As shown, the apparatus 800 includes: a first processor; and a first memory, connected to the first processor, for providing the first processor with instructions for processing the following processing steps: linking from the second block receiving data; encrypting the data to generate encrypted encrypted data; using the public key of the node user of the second blockchain to encrypt the key used to decrypt the encrypted data, thereby generating encrypted key information; and Using encrypted data as a block body and encrypted key information as a block header, a block corresponding to the received data is generated.

[0081] Optionally, using the public ...

Abstract

The invention discloses a data processing method and device applied to a blockchain node and a storage medium. The method comprises the steps that a first node of a first blockchain receives data from a second blockchain; the first node encrypts the data so as to generate encrypted data; the first node encrypts a secret key used for decrypting the encrypted data by using a public key of a node user of a second block chain so as to generate encrypted secret key information; and the first node generates a block corresponding to the received data by using the encrypted data as a block body and the encrypted key information as a block head.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular to a data processing method, device and storage medium applied to block chain nodes. Background technique [0002] Due to the distributed storage and non-tamperable data characteristics of blockchain technology, more and more business fields have begun to use blockchain technology for data storage and processing. For each user participating in the blockchain, since they often involve different business fields, the same user may store data in different blockchains. Therefore, when the user conducts transactions with another user on one blockchain or handles other practices, it may be necessary to read the data information recorded by the user on another blockchain. [0003] For example, if a user is a user of a consortium chain, when the user needs to conduct transactions or transaction processing with another user on the public chain, it is often necessary to call the...
