Embodiment 1

[0028] refer to figure 1 As shown, it is a schematic diagram of the steps of a blockchain private transaction method provided by the embodiment of this specification, wherein the members of the private transaction include the transaction initiator user and the transaction associated user on the blockchain node; the method may include the following steps:

[0029] Step 102: the transaction initiating user sends the encrypted transaction content to the transaction associated user through the p2p network;

[0030] Step 104: The transaction-associated user decrypts the received transaction content, obtains the calculation result through its local calculation program, and performs hash processing on it to obtain the first result hash;

[0031] Step 106: The transaction-associated user sends the first result hash and its own signature to the transaction initiating user;

[0032] Step 108: The transaction initiating user obtains a second result hash after locally verifying and signi...

Embodiment 2

[0053] This embodiment specifically provides a blockchain private transaction device, wherein members of the private transaction include transaction initiators and transaction associated users on blockchain nodes; the device includes:

[0054] The first sending module 202: used for the transaction initiation user to send the encrypted transaction content to the transaction associated user through the p2p network;

[0055] The first processing module 204: used for the transaction associated user to decrypt the received transaction content, obtain the operation result through its local calculation program and perform hash processing on it, and obtain the first result hash;

[0056] The second sending module 206: used for the transaction-associated user to send the first result hash and his own signature to the transaction initiation user;

[0057] The second processing module 208: used for obtaining the second result hash after the transaction initiation user performs local veri...

Embodiment 3

[0068] Refer below figure 2 The electronic equipment of the embodiment of this specification is introduced in detail. Please refer to figure 2 , at the hardware level, the electronic device includes one or more processors and memory. Optionally also include internal bus and network interface. Wherein, the memory may include a memory, such as a high-speed random-access memory (Random-Access Memory, RAM), and may also include a non-volatile memory (Non-Volatile Memory), such as at least one disk memory. Of course, the electronic device may also include hardware required by other services.

[0069] The processor, network interface, and memory may be interconnected via an internal bus, which may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an extended industry standard Structure (Extended Industry Standard Architecture, EISA) bus, etc. The bus can be divided into address bus, data bus, control bus and so on. For convenie...

Abstract

The embodiment of the invention relates to a blockchain private transaction method and device and electronic equipment. The method mainly comprises the steps that a transaction initiating user sends encrypted transaction content to a transaction associated user through a p2p network; decrypting the received transaction content by the transaction associated user, obtaining an operation result through a local calculation program of the transaction associated user, and performing hash processing on the operation result to obtain a first result hash; the transaction associated user sends the firstresult hash and a signature of the transaction associated user to the transaction initiating user; and the transaction initiating user locally verifies and signs the first result hash to obtain a second result hash, and broadcasts the second result hash to other blockchain nodes. By means of the technical scheme, it can be guaranteed that the privacy information of the user level only circulatesamong participating user parties, and a large amount of calculation is not needed.

Description

technical field [0001] The embodiment of this specification relates to the field of network technology, and in particular to a blockchain private transaction method, device and electronic equipment. Background technique [0002] In the current blockchain system, blockchain systems under different application scenarios are differentiated according to the degree of network centralization. The consortium chain system allows authorized nodes to join the network, and can view information according to permissions, and is often used in inter-institutional blockchains. But there are still the following problems: each operator of the alliance chain runs nodes, and each node is connected to different users. When a user sends transaction information to the node to which it belongs, the content of the transaction is completely open to the node. That is, the user's privacy cannot be guaranteed on the node to which he belongs, and the node still has the possibility of leaking its transac...
