With the characteristics of decentralization, persistency, anonymity and auditability, blockchain technology is a new tool to solve the product traceability, information security and privacy, payment efficiency and cost reduction in cross- border e-business. This paper summarizes the problems of traditional cross-border e-business payment forms, analyses the probability of blockchain technology application in cross-border e-business payment field. The research focuses on blockchain- based letter of credit payment under cross-border B2B e-business condition, introducing a blockchain-based payment application framework. Following the framework, this study discusses the hierarchy and functional modules of a blockchain-based cross- border e-business payment platform. This paper proposes three levels chain structure and data classification management to construct an alliance chain with traders, customers, banks and regulators in the cross-border e-business

EXISTING SYSTEM :

The characteristics of decentralization, persistency, anonymity and auditability of blockchain technology, the properties of immutability, transparency and natural settlement, in fact, completely match the demand of the cross-border e- business payment field. Blockchain technology provide a new probability solution to innovate the cross-border e-business payment model, such as using crypto-currency as intermediary for money-exchanging, constructing decentralization global remittance system with blockchain technology and underlying protocol by integrating global banks. Now in cross-border B2B e-business transaction process, blockchain-based letter of credit is actually becoming an innovation payment instrument and it is particularly useful where the buyer and seller may not know each other personally and are separated by distance, differing laws in each country, and different trading customs.

EXISTING SYSTEM DISADVANTAGES:

1.LESS ACCURACY

2. LOW EFFICIENCY

PROPOSED SYSTEM :

In the application of the L/C finance and trade, block chain can advance the process electrolization and improve the accuracy. Once the bank transactions through their own system, and then paper or other methods to the hands of trading partners, block chain system after the construction of the entire process electronic, to ensure the authenticity of the content. The whole process is transparent, and everyone can see the progress of the process and the future arrangement. In addition, each action will also have a system to record it. Basic workflows for the L/C finance and trade involve four different partners: buyers, sellers, corresponding banks and regulators. Yes, there are a lot of commercial and freight documents, bank documents in transactions, which are largely paper-dependent. In fact, all documents can be placed on the block chain and in the form of cryptography, electronic signatures are added to ensure their authenticity. By building standardized shared platforms, different banks can also join

PROPOSED SYSTEM ADVANTAGES:

1.HIGH ACCURACY

2.HIGH EFFICIENCY
