The industrial circle and academic circle have begun to realize the importance and value of Blockchain payment security, and have carried out active exploration now. However, the current Blockchain payment is still in the early stage of industrial development with systematic study lacked. PayYoda analyzes the Blockchain payment security demand characteristics and defines the Blockchain payment security boundary, laying the foundation of Blockchain payment security reference frame.

Blockchain payment problem: Serious security privacy problem and lack of trust between both parties of the transaction

The traditional payment way is always of high risk, poor efficiency and many restrictions. Especially for the international trade, the buyer shall transfer money to the supplier’s account which needs to be confirmed by many international banks midway with complicated formalities and a long time taken (varying from several days to ten days and a half months) after a deal is closed. More importantly, the account is often frozen for no reason and the high service charge needs to be paid in the whole process because all countries have strict regulations on the amount and types of transactions when international payment. Furthermore, the centralized settlement system is with non-transparent data and unsafe hidden dangers, so the personal information may be disclosed.

Based on the problem, PayYoda puts forward the solution:

I. Credit-driven ecosystem

PayYoda constructs the credit-driven ecosystem by the credit scoring system to solve the security payment problem. Various payment security accidents (including merchant fraud, malicious user attack, phishing site and privacy disclosure) happen to the online payment and offline payment. How to create a safe payment environment becomes the high-priority tasks of all the payment networks.

The PayYoda ecosphere is credit-driven. To achieve the goal, related measures (including credit-driven ecology, merchant caution money, safety fund, privacy protection, credit score, and decentralized risk control anti-fraud) shall be taken to ensure the user asset security in many fields thoroughly.

II. Publicity, transparency and traceability

In addition to this, PayYoda’s strategy is solving the data source and data trust problems by its hardware equipment with machine language, and ensuring the data authenticity of the whole chain based on Blockchain characteristics-decentralization and immutability. The PayYoda’s design ensures the payment transaction data security in the process of acquisition, transmission, storage and computation with stable and reliable technology platform provided for data transmission and value circulation on the digital asset trading.

III. Decentralizing the payment on the Blockchain

After PayYoda implements the actual scenario of digital currency and realizes the integration with payment transactions via Blockchain, it won’t rely on the system in the central position for fund clearing and trading information storage any longer, but can transfer the value directly based on consensus mechanism which doesn’t need any trust coordination. The mechanism transformation result is as follows: On one hand, the huge service cost and maintenance costs of the third party of the third party institution are saved, the business process is simplified and the business costs for banks and customers are lowered; On the other hand, the flattening of the process increases the transfer speed and realizes the real-time transfer, and the security of the whole system can be ensured even though multiple nodes are attacked because a complete set of data copies is stored at each node of the system.

IV. Secure trading system based on artificial intelligence

The PayYoda secure trading protection system is based on multi-core concurrent technology, integrated safety engine technology, zero-copy technique, and other high performance architectures. It integrates ten layers of fine filtering function based on data header and data content (including DOS defense, user authentication, application control, intrusion prevention, site classification and filtering, virus filtration, web application defense and data leak prevention), forms the integrated security defense system from the network layer to the application layer, and realizes the clean flow delivery.

On the basis of artificial intelligence, PayYoda provides such abilities as data analysis, knowledge extraction, independent study, intelligent decision and automatic control which can create the innovative applications in the fields of network information security (such as network protection, data management, message audit, intelligent security and financial risk control).

V. Construction of sustainable payment ecosystem

The sustainable evolution of the platform (as the basic payment network) is of great importance. And the continuous evolution of the platform happens due to sustainable innovation ability in the premise of abiding by common rules. The common rules of the platform are ensured by the governance mechanism and consensus mechanism. As for the innovation, the development history of e-payment in these decades clearly shows: As long as the power is given to the innovators closest to the market, there will always be an endless supply of ideas. In terms of governance mechanism, PayYoda adopts the fully open ecological model so that the ecosphere participants can focus on the tasks they are best at and maximize their respective profits by the corresponding incentive mechanism with innovation driven via the market end.

PayYoda will continue to be rooted in the Blockchain-fertile soil and cooperate with various financial institutions and entity industries to build the decentralized payment ecology together based on Blockchain in the future!
