Description

Universal blockchain wallet platform system

Technical Field

The invention relates to the technical field of network payment, in particular to a universal block chain wallet platform.

Background

In the current cashless era, virtual digital currency makes the way, the market for trading by using the digital currency is larger and larger, and a convenient and safe block chain wallet provided for users becomes an industry foundation. The general block chain wallet docking platform utilizes offline signature packaging transaction, the private key and the user password are stored in an isolated mode, the user password is stored by using an asymmetric encryption technology, and the functions of recharging and extracting the mainstream coins such as BTC, ETH and EOS in the current market are realized on the premise that the application security is guaranteed by using the user password to encrypt and decrypt the private key. And due to the reasonable architecture, new digital currency types can be easily added. For the butt-joint party, the basic recharging and cash-drawing function can be realized only by simply calling an interface based on an http protocol and subscription information according to a butt-joint document provided by the platform, and the butt-joint party can realize the basic recharging and cash-drawing function only by focusing on the service of the butt-joint party without concerning the realization of the bottom layer area block chain.

The existing block chain wallet platform does not make a distributed cluster version because of few butt-joint parties and low transaction flow. Although sufficient at present, the situations of slow response, network congestion and the like can occur in high-throughput and high-concurrency scenes. In the future, as a robust high-availability platform, distributed, business and database clusters, high-availability schemes are all processes that must be experienced.

In the prior block chain transaction project development, the core problem of the project is to improve the response speed, the throughput, the development of the wallet, the safety of the user assets and other core and weak business contents of the transaction. Various attempts are made by various exchanges to realize the function of the wallet, however, the problems of coin loss, wrong address transfer, transfer failure and the like are endless, and the mutual reference difficulty is very high when the exchanges are realized based on different languages.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a universal blockchain wallet platform, which effectively reduces the development cost of each connected project party, reduces the development difficulty of each project, shortens the time of the project appearing, puts more energy and time on the core business realization and provides better interactive experience for users by realizing a low-coupling and independent blockchain digital currency transaction transfer platform.

The technical scheme adopted by the invention for solving the technical problems is as follows: the universal block chain wallet platform comprises a wallet programming interface module, a wallet task module, a message queue module (short for MQ), a plurality of service system modules and a plurality of block chain link points which are connected by data, wherein the address of each block chain node corresponds to one service system module; the wallet programming interface module encapsulates a unified digital currency operation function and a tool bag, the wallet programming interface module converts a business function into a transfer operation on the block chain link points according to a request of a client, the wallet task module reads transaction records on the block chain link points, and when records matched with the business system addresses are found, the message queue module respectively feeds back transaction record data and conversion persistence data to the corresponding business system modules and modifies user asset records.

Furthermore, the wallet programming interface and the wallet task are connected with CoinJS (WEB component library), unified digital currency operations and toolkits are packaged in the CoinJS, and chain transfer can be carried out on the service by referring the library by the wallet programming interface and the wallet task.

Further, the client is a user-oriented blockchain application or an exchange item.

Further, when the client applies for the wallet function, the following steps are executed:

1. applying parameters required for docking to a wallet programming interface module, such as an api, a secret key and the like for authentication, and defining a system identifier of the wallet for a platform to identify;

2. subscribing the notice of the asset change event through the message queue module, and changing the self user account book after receiving information such as money charging to account, money extraction success and the like;

3. the wallet programming interface module generates addresses of corresponding block link nodes, applies for money extraction, and obtains interfaces which realize wallet functions such as currency and the like and are connected to the corresponding business system module in an abutting mode;

4. and the operation department manages users to log in the service system module according to the provided desktop program to make a decision of money withdrawal service (whether money is passed or not, whether money is put or not and the like).

The invention has the beneficial effects that:

1. unified digital currency operation and toolkits are packaged in the CoinJS library, and chain transfer of business can be carried out only by using the library through data connection and reference of a wallet programming interface and a wallet task, so that more detailed professional division of labor is realized, the wallet is more stable in performance on a basic layer, and the wallet development efficiency and the operation efficiency are higher;

2. in a service interface of a wallet programming interface, when an application system requests to generate a block chain address, a user password sha-256 encryption algorithm is stored in a mysql database, and a wallet address private key is subjected to aes symmetric encryption by using an encrypted user password and then stored in a mongodb database, so that isolated storage of the password and the key is effectively realized, transactions including collection and withdrawal of coins and transfer accounts are packaged and broadcast transactions after local offline signature, and the safety of user assets is ensured to the maximum extent;

3. the whole wallet system is independent of the application service, and the wallet programming interface and the MQ are used as a communication channel to realize data interaction with the application system, so that the system coupling degree is reduced;

4. various operations of different currencies are uniformly packaged, a uniform access mode is provided for the outside, development difficulty is reduced, implementation details are shielded, and safety guarantee is provided.
