Research On Credit Risk Model Of Internet Finance Based On Blockchain Technology

Blockchain is an information storage data structure based on P2 P network.This book has one basic attribute: Once a data is recorded in any one node of the chain of the blockchain,it is impossible to change again.A blockchain is a chain of blocks.Instead of using a central entity or a third-party database to manage the chain,blockchain uses a peer-to-peer network(P2P network).Anyone can join.When someone joins,he gets a complete copy of the information transaction.The new block is distributed to everyone on the network and each block is verified to ensure that it has not been tampered with.If all the content is verified,the block is considered valid,and it can be allowed to join the end of the blockchain,creating a new blockchain to ensure that the chain is the longest effective chain.The accepted block is considered as a random hash prior to the new block.This decentralized information preservation mechanism can effectively guarantee the security of information.Internet finance is essentially the exchange of values across time and space.Unlike traditional finance,however,the main body of public trust in traditional finance is the central bank,while the central bank has the obligation to pay it rigidly,but there are also powers that can be abused.The credit record established on the Internet is a record that can be queried.Internet finance in the narrow sense tends to establish direct connections between peers.In China,there are mainly individual-to-person loans,such as loans from everyone;there are also individual loans to small and medium-sized enterprises,such as Zhaocaibao;personal money funds,such as Yu Bao;Personal to gold futures funds,such as Chuang Jinbao.Internet finance in its broad sense includes not only those above,but also crowdfunding and third-party payments,such as Anthusker and Alipay.Internet finance can greatly reduce the threshold and increase efficiency.Using blockchain technology can greatly reduce the credit risk of internet finance.Based on the blockchain technology trading mechanism,this paper quantifies credit risk based loon blockchain and P2 P models and designs a new credit transaction model..
