Embodiment Construction

[0091] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0092] The technical solution involved in the present invention is completed through the Ethereum smart contract. The Ethereum smart contract is a code that can run on the Ethereum virtual machine. It is called a "contract" because the user can run it through this code. Code on Ethereum to control valuable things, such as digital currencies such as Ethereum or other digital asset entities.

[0093] The protocol mainly used in this application is the ERC (Ethereum Req...

Abstract

The invention discloses a private key storage method and device based on a blockchain contract technology. The method comprises the following steps: sending a transaction request to N approval ends atthe same time, wherein N is an odd number not smaller than 5; obtaining an approval result of an approval end according to the transaction request; and executing corresponding operation according tothe approval result. According to the application, no server needs to be deployed except for scripts used for enhancing security, so that complete decentralized operation is realized, whether to perform transfer operation or not is determined through the preset voting rule and according to the judgment result of the rule, and an approver is changed from keeping a private key to keeping a Token, sothat the risk and the pressure of the approver are greatly reduced; and moreover, once an accident occurs, other approvers can be immediately informed to transfer funds, and any approver can immediately stop the transaction process, so that the safety is relatively high.

Description

technical field [0001] The present invention relates to the technical field of digital asset storage management, in particular to a private key storage method and device based on blockchain contract technology. Background technique [0002] Ethereum's private key (Private Key) is a string of 64-bit hexadecimal characters (32 bytes), which is equivalent to a bank card password and is used to prove the ownership of digital assets under the corresponding address. The owner must sign the transaction message with the private key to prove that the publisher of the message is the owner of the corresponding address. Without the private key, the transaction cannot be signed. As a bearer currency, the evidence of ownership cannot be recognized on the network, so the Ethereum cannot be used. The Ethereum network will confirm the private key with the public key during the transaction. Mastering the private key is equivalent to mastering other Corresponding to the digital assets stored ...
