The identity refers to an attribute set related to entities such as natural people and legal people, and in the financial distributed account book system, the identity can be digitally identified, and an account is an attribute set of the identity.
In the process of creating the account, each account is associated with an identity, the transaction data carries the account identity of a sender, the identity of the account is globally unique in the distributed account book system and is not easy to be falsely used, and the anonymization processing of the account identity is supported for a system with a privacy protection requirement.
At present, in the block chain technology, the transaction between accounts adopts an account address as a unique identifier representing a source account and a target account, and the following problems exist:
(1) the account address is longer, is generally 20-64 characters in length, contains upper and lower case characters and numbers, and is not beneficial to the memorization and identification of a user;
(2) account addresses are easy to be confused, and generally, in the using process, when accounts are compared manually, only partial character strings at the beginning and the end of the accounts are compared, and the probability of errors of the middle part is still relatively high.
(3) The account address is not visual, the character strings in the account address are basically arranged and combined in disorder and meaningless, and the character strings cannot form visual correspondence with the user identity.
Disclosure of Invention
In order to solve the problems existing in the prior art that the transaction between accounts in the prior block chain technology adopts an account address as a unique identifier for representing a source account and a target account, the invention discloses a block chain account identity identification method, which can locate the block chain address of an associated account according to the identity by using the obtained identity, and indirectly inquire the information of the account in a block chain account book; the source account and the target account may also be designated in the transaction element by an identification.
A method for identifying identity of a block chain account comprises the following steps,
receiving a command for setting an identity identifier for a blockchain account, wherein the setting command is a string of characters with the length of 1-255, the string of characters does not contain a blank space, the string of characters is set by a user, and the user has an address and a private key of the blockchain account;
checking the standardization, the length and the global uniqueness of the character string codes;
associating the character string which is qualified by inspection and the hash value thereof with the account address;
using the character string associated with the account address as an account identity;
and returning to reset the character strings which are not qualified in the check.
Further, the character string is obtained by any one or more of capital letters, lower case letters, numbers and symbols.
Further, an account state tree is set, the structure of the account state tree contains an account address, other attribute branches and Name attribute branches of the account are arranged under the account address, the Name attribute is limited to be set only one time, set once, not allowed to be modified and not allowed to be deleted, and the hash value of the qualified character string is stored in the Name attribute branch.
Further, a block chain account book user state space is set, and is used for checking whether the qualified character strings and the hash values thereof are associated with the account addresses, storing the checked qualified character strings and the hash values thereof in the block chain account book user state space, and establishing one-to-one mapping relation objects between the character strings and the hash values thereof as well as the account addresses.
Further, whether the account has set the identity can be judged by inquiring whether the Name attribute branch has been set in the account status tree.
The invention has the advantages that the invention provides a block chain account identity identification method, which uniquely represents a block chain account on a block chain through a user-defined character string identification, supports the chain data of the account indexed on the chain through the identification, supports the transaction parties using the identification to indicate the block chain in the transaction, introduces the identification method of the block chain account identity, can improve the readability, the memorability, the usability and the distinguishability of the block chain account address, realize more convenient and rapid application of the block chain technology in the Internet environment, lead the user of the block chain to be capable of identifying the block chain address and the self-defined identity, the association of accounts such as name, mobile phone number, mailbox, etc., is equivalent to setting a unique alias for the blockchain account, and meanwhile, a public block chain address and the capability of digital signature are provided for the self-defined identity.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail below, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all embodiments, and other embodiments obtained by those skilled in the art based on the embodiments in the present specification should fall within the protection scope.
The technical solutions provided by the embodiments in the present specification are described in detail below, and it should be noted that the following embodiments can be understood by referring to each other since the technical ideas based on the following embodiments are similar.
Example 1: a method for identifying the identity of a block chain account,
(1) the method comprises the steps that a user firstly obtains ownership of an account on a block chain, namely obtains an address and a private key of the account;
(2) the user defines a meaningful character string as a unique identity of the block chain account, the character string consists of a-Z, A-Z, 0-9, @ # $ & -with the length of 1-255, and a space cannot be reserved in the middle;
(3) setting a Name attribute branch of a blockchain account in an account state tree (as shown in fig. 1), wherein the Name attribute of the blockchain account is only allowed to be set one time, is only allowed to be set once, is not allowed to be modified, and is not allowed to be deleted, an account address is contained in the account state tree structure, and other attribute branches and the Name attribute branch of the account are arranged under the account address;
