Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In addition, the technical features mentioned in the embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

Digital currency, including bitcoin, etherhouse, rembo coin, bitcoin cash, etc., is the underlying layer of clearing digital assets whose economic activities depend on digital currency.

The digital currency trading platform, also called as digital asset trading platform, mainly provides trading digital currency or digital asset matching trading service for people, and provides the process of buying and buying trading digital assets through the digital currency trading platform, namely the process of exchanging one digital currency to another digital currency, and the trading between digital currencies also urges the trading of legal currencies against digital currencies, which is the source of centralized trading platform, and the current popular trading of legal currencies and digital currencies includes U.S. dollars, euros, yen, australia dollars, and the like.

The traditional exchange relies on security traders, which belong to a pyramid structure, users gather at the security traders, funds are deposited in banks, securities are registered and settled at third-party institutions, essentially, trading places only provide functions of matching, supervision assistance, information assistance and the like, due to the decentralized characteristic of the digital currency, the digital currency transaction platform belongs to a flat structure, the asset management is built in the exchange, therefore, any transaction platform does not need a third party institution to register settlement digital currency, thereby bringing about the characteristic of easy deployment on business architecture, and finally, user traffic and fund traffic are all converged at a digital currency exchange, and in combination with the technical architecture, the centralized digital currency transaction platform is closer to the technical architecture of internet application, which is essentially the combination of a financial transaction system and internet network services, and has the following advantages: the system can support massive high-concurrency real-time matching transactions and full-platform support of the user terminal, is not consistent from a desktop to a mobile terminal, has ultrahigh liquidity of digital assets, and can obtain ultrahigh profit and value discovery functions by the platform.

Referring to fig. 1, fig. 1 is a schematic diagram of an application environment according to an embodiment of the present disclosure;

as shown in fig. 1, the electronic device equipped with the digital wallet and the POS device access a lightning network access layer, the lightning network access layer connects a lightning network of digital money, the lightning network of digital money includes a plurality of lightning networks of digital money 1, digital money 2, …, and digital money N, wherein each lightning network of digital money corresponds to a digital money or a digital money identifier, wherein each lightning network of digital money accesses a transaction network of digital money, the transaction network of digital money is used as a transaction platform of digital money for providing transaction service of digital money, it is understood that, in order to eliminate the influence of a third party trusted authority, the transaction network of digital money is a block chain system based on block chain technology, and the block chain system has an decentralized feature, unlike traditional centralized servers, the blockchain system does not have centralized nodes, and requires a consensus mechanism to maintain normal operation, for example, the consensus mechanism includes POW algorithm, and based on the POW algorithm, the blockchain system can achieve consensus verification of the blocks.

The POW algorithm is a strategy for dealing with denial of service attacks and other services abuses, and a workload certification refers to a data calculation that satisfies a specific condition, which is difficult to generate a correct result, but is simple to verify the correct result. The generation of correct results can only be verified and tried by continuously enumerating random numbers, so that correct answers are finally found. Wherein, the verification trial and error is realized by adopting a hash (hash) algorithm. The hash algorithm is a one-way hash algorithm, the process of calculating the hash value is simple, but the original data can be obtained reversely according to the fixed hash value only by enumeration trial and error.

When random hash operation is performed, the POW algorithm introduces a scanning operation on a certain value, for example, in SHA-256, a random hash value starts with one or more 0 s, and as the number of 0 s increases gradually, the workload required for traversing the solution corresponding to the random hash value under the condition increases exponentially, and only one random hash operation is required for checking the result.

Some blocks of a virtual cryptocurrency system are supplemented with a random number (Nonce) that needs to satisfy the condition of a prescribed number of 0's required to cause the hash value of a given block to appear. Due to the irreversible nature of the hash operation, it is only possible to traverse the random numbers that satisfy the condition by trial and error.

As long as the block chain node traverses the random number meeting the condition, the block chain node completes the proof of the workload, thereby obtaining the packing accounting right of the block.

In the world of blockchain, nodes around the world participate in accounting for blockchain networks in common. For example, bitcoin solves the hash puzzle for the block generated by packaging through a workload proving mechanism, and the miners submit the result to the network to wait for other nodes to verify and confirm the block. The nodes express their identities by means of public keys and exercise the right to transfer themselves by means of private keys.

All transaction data, whether in bitcoin or ether house, and the wide variety of public chains that appear later, is exposed in the clear on the blockchain. Although the identity of a person cannot be judged only by the public key, the disclosure of the transaction data makes account tracking feasible, and thus the privacy of the transaction behavior of the account cannot be protected.

In the design of the ChainStack block chain, an original consensus mechanism of deterministic POW is adopted, and in the consensus mechanism, two roles of miners and verifiers exist. Miners need to carry out Hash calculation to solve the mathematical problem, and verifiers verify the blocks of the miners through a practical Byzantine fault-tolerant consensus algorithm and finally submit the blocks to a network. Other nodes accept a block by only verifying the verifier's signature, and such acceptance is deterministic rather than probabilistic validation like bitcoin.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating an architecture of a block chain system according to an embodiment of the present application; as shown in fig. 2, the blockchain system 20 includes: the system comprises three block chain nodes, namely a common node 21, a miner node 22 and a verification node 23. All the blockchain nodes in the blockchain system have the functions of common nodes, that is, all the blockchain nodes can be a sender of a transaction and can also be a receiver of the transaction.

Any two of the ordinary node 21, the miner node 22 and the verification node 23 support Point-to-Point communication (P2P), and the ordinary node 21, the miner node 22 and the verification node 23 can all be used as block link points in the block link system, and each of them undertakes different responsibilities in the block link system, and commonly maintain the work, stability and safety of the block link system.

The normal node 21 holds the circulated electronic money and has the right to vote in the blockchain system. The regular node 21 may perform the relevant transaction operations but does not have the block's packaged accounting rights. The regular node 21 can only synchronously record block data from the relevant nodes having the packed accounting right. The generic node 21 may be the sender of the transaction or the recipient of the transaction.

The miner node 22 is responsible for computing the hash problem and finding out the blocks. The block is generated based on a random number satisfying a predetermined condition. In some embodiments, the block is generated by the mineworker node 22 using a Proof of Work (POW) algorithm, i.e., the hash value to be verified calculated based on the block's random number is less than the target hash value. Wherein, the miner node 22 is converted from the common node 21 by starting the ore excavation mode.

The verification node 23 is used to identify the verification blocks and record the blocks passing the verification onto the block chain. Wherein, the verification node 23 is generated after the ordinary node 21 submits a registration application and votes for election.

It is understood that the above general node 21, the miner node 22 and the verification node 23 may be a physical server or a logical server virtualized by a plurality of physical servers. The server may also be a server cluster formed by a plurality of servers capable of communicating with each other, and each functional module may be respectively distributed on each server in the server cluster.

In the embodiment of the present application, the digital currency includes bitcoin, ether house, rembo coin, bitcoin cash, etc., and the following describes the transaction process of the digital currency by taking the digital currency as the bitcoin as an example:

the underlying network protocol used by bitcoin is TCP/IP protocol, the P2P network of bitcoin is constructed based on TCP, the default communication port of the main network is 8333, wherein, the topology of the P2P network has a plurality of topologies, such as: the method comprises a centralized topology, a semi-centralized topology and a fully distributed topology, wherein a network formed by all nodes of bitcoin is a fully distributed topology, the transmission process between the nodes is closer to a 'flooding algorithm', namely, a transaction is generated from a certain node and then broadcasted to adjacent nodes, and the adjacent nodes transmit one by one and ten by one to hundred until the transaction is spread to the whole network.

Node discovery, which is the first step in any blockchain node access blockchain P2P network, can be divided into initial node discovery, which means that a node is running for the first time without node data, and post-startup node discovery, which means that a running wallet can already dynamically maintain available nodes following the network.

Specifically, the transaction process of Bitcoin (Bitcoin, BTC) and etherhouse (ETH ) digital currency is as follows:

procedure for user a to take 0.01BTC for 10ETH of user B:

step (1), the user A hangs 10ETH purchase orders, bids 0.01BTC, enters a matching system order book ETH-BTC purchase order queue through a Web service system, waits for matching transaction, and meanwhile, the fund management system freezes 0.01 BTC.

And (2) hanging 10ETH (Ethernet for sale) orders by a user B, bidding for 0.01BTC, entering an order book ETH-BTC order queue of a matching system through a Web service system, successfully matching with the order match of the user A in the step (1), generating Trade, simultaneously settling corresponding assets by a fund management system, wherein the asset change of the user B is to increase 0.01BTC and reduce 10ETH, and the asset change of the user A is to increase 10ETH and reduce 0.01 BTC.

And (3) writing an RDB (remote data base) by the transaction Trade and the asset change through a fund management system to form a transaction record, updating the market quotation, and inquiring the database record by a user and an operation background management system, wherein the step (3) is not registered on the block chain.

And (4) initiating a money withdrawal request by the user B through the Web service system, requesting to withdraw 10ETH to enter a digital money wallet of the user B, entering the fund management system, observing the request by an operator of the exchange through an operation background, and auditing the information of the user B by the operator, such as whether real-name authentication is normal or not.

And (5) after the money withdrawal request enters the operation system, if the money withdrawal request passes the audit, the fund management system freezes 10ETH of the user B, meanwhile, the money withdrawal request is sent to a digital money wallet service system, namely Waleltgroup, and the subsystem sends a transaction x (transaction) on a block chain to wait for the transaction to be packed and provide the user with the view according to the updated money withdrawal audit state.

And (6) the digital currency wallet service inquires whether the transaction x is packaged according to the block information, if the transaction x is packaged, the fund management system completely and directly wipes 10ETH frozen by the user B into 0, the currency extracting state is updated to be finished, and the block transaction ID is provided for the user and the operation background system to inquire. The digital currency wallet service can provide an API with a unified interface for other modules of a transaction platform, different data are structured into database service, and finally transaction inquiry and verification can be completed through a traditional high-availability means.
