Embodiment Construction

[0067] Embodiments of this specification will be described below with reference to the accompanying drawings.

[0068] figure 1 A blockchain account maintenance system according to an embodiment of this specification is shown. Such as figure 1 As shown, the system includes a plurality of full nodes (six full nodes are schematically shown in the figure) that constitute the block chain. The block chain is a consortium chain, in which each full node is a node that can participate in the consensus in the consortium chain, which is equivalent to each server of the blockchain platform, and each of the full nodes is a trusted node, which cooperates with at least one trusted organization Corresponding. The system also includes a client 14 and a client 15 of the block chain. The client is, for example, a light wallet node in the block chain, which relies on the above-mentioned full nodes for transactions. Wherein, the client 14 is, for example, a client of a first account of a firs...

Abstract

The embodiment of the invention provides a method and a device for storing biological characteristics of a user into a block chain and a method and a device for resetting an account key. The method for storing the biological characteristics of the user comprises the following steps: acquiring the biological characteristics of a first user; obtaining a trusted user list, the trusted user list comprising respective account identifiers of at least one second user, and the at least one second user being a preset trusted user of the first user; and sending a first transaction used for setting the biological characteristics to any full node in the block chain, wherein each full node in the block chain sets a biological feature and a trusted user list corresponding to the first account in a localaccount database of the full node, and the data field of the first transaction comprises the biological feature and the trusted user list.

Description

technical field [0001] The embodiment of this description relates to the field of blockchain technology, and more specifically, to a method and device for storing user biometrics in a blockchain, and a method and device for resetting a blockchain account key. Background technique [0002] In the new generation of blockchain, such as Ethereum, the concept of account is added, wherein the account created by the user is an external account in Ethereum. Usually, each external account has a pair of public and private keys, where the private key is used for digital signatures, and the public key is used to verify signatures. In addition, in each node, the data table of all accounts in the blockchain is maintained in the form of a state tree in the local database of the node. The state tree is the mapping between the account address and the account content. The account content includes, account Balance, account key information (hash value), etc. Before making a transaction, the u...
