Abstract

The invention provides private key generation and data interaction methods for a block chain and systems thereof. The generation method comprises steps of acquiring registration account information input into the block chain, wherein the registration account information comprises a login password of the registration account; determining a generation factor of a to-be-generated private key according to the registration account information with the login password of the registration account removed; and generating the private key according to the generation factor. The private key generated through the method can be retrieved, thereby preventing huge loss due to permanent freeze of assets and data in the block chain node resulting from loss of the private key; further, the private key can beretrieved without monitoring or reviewing by a third party, so that the private key is protected and can be retrieved conveniently, and the user data and assets can be protected effectively.

Description

technical field

[0001] The present invention relates to the technical field of block chain key generation, and more specifically, to a block chain private key generation, data interaction method and system thereof. Background technique

[0002] Blockchain can realize asset digitization and cross-platform circulation. In the blockchain transaction, the user needs to use the private key signature to prove the consumption right of the asset to other nodes in the blockchain network. The private key is equivalent to the user's ID card or the user's bank card password, etc. Its storage and Management is very important.

[0003] The private key is generally generated by a system random number encrypted by the elliptic curve encryption algorithm. The system random number can guarantee the uniqueness of the private key and cannot be reversed, which can ensure the uniqueness of the private key; the user's private key is stored in the user's private In the block chain node, if the re...

Embodiment Construction

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 making creative efforts belong to the protection scope of the present invention.

[0072] In the blockchain, if redoing the system, deleting nodes, and deleting private keys will cause the loss of the private key and cannot be retrieved, then the assets and data in the blockchain node will be permanently frozen, causing great losses.

[0073] Based on this, the embodiment of the present invention provides a method for generating a blockchain private key. The method determines the generation factor of the private key to be generated according ...
