Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

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

Digital currencies, including Bitcoin, Ethereum, Ripple, Bitcoin Cash, etc., are the bottom layer of the settlement of digital assets, and the economic activities of digital assets rely on digital currencies.

The digital currency trading platform, also known as the digital asset trading platform, mainly provides people with trading digital currency or digital asset matching transaction services. The digital currency trading platform provides the process of buying and trading digital assets, that is, from a digital currency exchange to Another kind of digital currency process, and the transaction between digital currency also gave birth to the transaction of legal currency to digital currency. This is also the origin of the centralized trading platform. The current popular legal currency and digital currency transactions include US dollars, euros, Japanese yen, Australian dollar, etc.

Traditional exchanges rely on securities firms and belong to a pyramid structure. Users gather at securities firms, funds are custodial in banks, and securities registration and settlement are in third-party institutions. In essence, trading venues only provide functions such as matching, supervision assistance, and information assistance. The decentralized nature of currency, the digital currency trading platform is a flat structure, and the asset management itself is built into the exchange, so any trading platform does not require a third-party institution to register and settle the digital currency, which brings easy business architecture. Deployment characteristics, user flow and capital flow will eventually all converge on digital currency exchanges. Combined with the technical architecture, the centralized digital currency trading platform is closer to the technical architecture of Internet applications. It is essentially a financial transaction system that is similar to Internet network services. In combination, it has the following advantages: it can support massive high-concurrency real-time matching transactions, user terminal full-platform support, from desktop to mobile, ultra-high liquidity of digital assets, platform can obtain ultra-high profits, value discovery Features.

Please refer to FIG. 1, which is a schematic diagram of an application environment provided by an embodiment of the present application;

As shown in FIG. 1, electronic devices and POS devices equipped with digital wallets are connected to the lightning network access layer. The lightning network access layer is connected to the lightning network of digital currency. The lightning network of digital currency includes multiple, respectively The lightning network of digital currency 1, the lightning network of digital currency 2,..., the lightning network of digital currency N, where each lightning network of digital currency corresponds to a digital currency or digital currency logo, where each type of digital The lightning network of currency is connected to the transaction network of digital currency. The transaction network of digital currency is used as a transaction platform of digital currency to provide transaction services of digital currency. Understandably, in order to eliminate the influence of third-party trusted institutions , The transaction network of the digital currency is a blockchain system based on blockchain technology, and the blockchain system has the characteristics of decentralization, which is different from the traditional centralized server, because the blockchain system does not have a centralized node. The consensus mechanism is required to maintain normal operation. For example, the consensus mechanism includes the POW algorithm. Based on the POW algorithm, the blockchain system can realize the consensus verification of the block.

The POW algorithm is a strategy to deal with denial of service attacks and other service abuses. A proof of work refers to a data calculation that meets specific conditions. It is difficult to produce correct results, but it is relatively simple to verify correct results. The correct result can only be verified by continuous enumeration of random numbers, so as to finally find the correct answer. Among them, the verification trial and error is implemented by using a hash algorithm. The hash algorithm is a one-way hash algorithm. The process of calculating the hash value is relatively simple, but to obtain the original data reversely based on the fixed hash value, it can only be done through trial and error enumeration.

When performing random hash operations, the POW algorithm introduces scanning for a specific value. For example, under SHA-256, the random hash value starts with one or more zeros, and gradually increases as the number of zeros. The amount of work required to traverse the solution corresponding to the random hash value in this case will increase exponentially, while checking the result requires only one random hash operation.

A random number (Nonce) is added to the blocks of some virtual cryptocurrency systems, and the random number needs to satisfy the condition that the hash value of a given block appears with a prescribed number of zeros. Due to the irreversible nature of the hash operation, it is only possible to traverse the random number that meets the conditions through repeated attempts.

As long as the block chain node traverses the random number that meets the conditions, the block chain node has completed the proof of the workload, thereby obtaining the block's packaging and accounting rights.

In the blockchain world, nodes all over the world participate in the bookkeeping of the blockchain network. For example, Bitcoin uses a proof-of-work mechanism in which miners solve hash puzzles on packaged blocks and submit the results to the network, waiting for other nodes to verify and confirm the block. Nodes use public keys to express their identities, and use private keys to exercise their right to transfer money.

Regardless of Bitcoin, Ethereum, and various public chains that appeared later, all transaction data is publicly disclosed on the blockchain in plaintext. Although the identity of a person cannot be judged only by the public key, the disclosure of transaction data makes account tracking feasible, and thus cannot protect the privacy of account transaction behavior.

In the design of the ChainStack blockchain, an original deterministic POW consensus mechanism is adopted. In this consensus mechanism, there are two roles: miner and verifier. Miners need to perform hash calculations to solve mathematical problems, and verifiers use the practical Byzantine fault-tolerant consensus algorithm to verify the miners' blocks and finally submit them to the network. Other nodes accepting the block only need to verify the signature of the verifier to accept a block, and such acceptance is deterministic, rather than probabilistic confirmation like Bitcoin.

Please refer to Figure 2. Figure 2 is a schematic diagram of the architecture of a blockchain system provided by an embodiment of the present application; as shown in Figure 2, the blockchain system 20 includes: a normal node 21, a miner node 22, and a verification node 23 Kind of blockchain node. Wherein, all the blockchain nodes in the blockchain system have the function of ordinary nodes, that is, all the blockchain nodes can become the sender of the transaction, and can also become the receiver of the transaction.

Ordinary node 21, miner node 22, and verification node 23 support point-to-point communication (P2P) between any two nodes, and ordinary node 21, miner node 22, and verification node 23 can all be used as blockchain systems Each of the blockchain nodes in the blockchain system assumes different responsibilities and jointly maintains the work, stability and security of the blockchain system.

Ordinary nodes 21 hold circulating electronic money and have the right to vote in the blockchain system. The ordinary node 21 can perform related transaction operations, but does not have the right to package and book the block. Ordinary nodes 21 can only synchronously record block data from related nodes that have the right to package and keep accounts. The ordinary node 21 may be the sender of the transaction or the receiver of the transaction.

The miner node 22 is responsible for calculating the hash puzzle and finding the block. Among them, the block is a block generated based on a random number meeting preset conditions. In some embodiments, the block is generated by the miner node 22 using the Proof of Work (POW) algorithm, that is, the hash value to be verified calculated based on the random number of the block is less than the target hash value of. Wherein, the miner node 22 is converted from the normal node 21 starting the mining mode.

The verification node 23 is used for consensus verification blocks and records the verified blocks on the blockchain. Wherein, the verification node 23 is generated after a registration application submitted by a common node 21 and elected after voting.

It is understandable that the aforementioned ordinary node 21, miner node 22, and verification node 23 may be a physical server or a logical server virtualized by multiple physical servers. The server may also be a server group composed of multiple servers that can communicate with each other, and each functional module may be distributed on each server in the server group.

In the embodiments of this application, the digital currency includes Bitcoin, Ethereum, Ripple, Bitcoin Cash, etc. The following takes the digital currency as Bitcoin as an example to illustrate the transaction process of digital currency:

The underlying network protocol used by Bitcoin is TCP/IP. Bitcoin's P2P network is constructed based on TCP. The default communication port of the main network is 8333. Among them, there are many P2P network topologies, such as centralized topology and semi-centralized topology. , Fully distributed topology, in which the network composed of all Bitcoin nodes is a fully distributed topology. The transmission process between nodes is closer to the "flooding algorithm", that is, transactions are generated from a certain node. Then broadcast to the neighboring nodes, and the neighboring nodes will be transmitted ten to ten, until the whole network is spread.

Node discovery is the first step for any blockchain node to access the blockchain P2P network. Node discovery can be divided into initial node discovery and post-startup node discovery. Initial node discovery refers to the first operation of the node without node data. After startup, the node discovery indicates that the running wallet has been able to follow the network to dynamically maintain available nodes.

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

The process in which user A exchanges 0.01 BTC for 10 ETH of user B:

Step (1), User A places a 10ETH buy order, bids 0.01BTC, enters the matching system order book ETH-BTC buy order queue through the Web business system, and waits for matching to be completed, and the fund management system freezes 0.01BTC.

Step (2), User B places a 10ETH sell order, bids 0.01BTC, enters the order book ETH-BTC sell order queue of the matching system through the Web business system, and successfully matches the order of A in step (1), generates Trade, and the fund management system Settlement of the corresponding assets, B’s asset change is increased by 0.01 BTC and decreased by 10 ETH, and A increased by 10 ETH and decreased by 0.01 BTC.

Step (3). Transaction Trade and asset changes are written to the RDB database through the fund management system to form transaction records and update market conditions at the same time. The database records can be inquired by users and the operation back-end management system. Step (3) is not registered to the blockchain on.

Step (4). User B initiates a coin withdrawal request via the Web business system, requesting to withdraw 10 ETH into his digital currency wallet. This request enters the fund management system. The exchange operator can observe the request through the operation background, and the operator will review it. User B's information, such as whether the real-name authentication is normal.

Step (5). After the withdrawal request enters the operating system, if it passes the review, the fund management system will freeze the 10ETH of user B, and at the same time initiate the withdrawal request to the digital currency wallet service system, namely WalletGroup, and the subsystem initiates the block Transaction x (Transaction) on the chain, waiting for the transaction to be packaged, and according to the updated currency review status, for users to view.

Step (6), the digital currency wallet service queries whether transaction x is packaged according to the block information. If it has been packaged, the fund management system will completely wipe the frozen 10ETH of user B to 0, and update the withdrawal status to complete. Provide block transaction ID for users and operating back-end systems to query. Among them, the digital currency wallet service can provide a unified API for other modules of the trading platform, and at the same time structure different data into the database service, and finally complete transaction query and verification through traditional high-availability means.
