Cross border payment risk under blockchain
blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. At present, they keep their own accounts.
In fact, the application mode of blockchain cross-border payment is to use blockchain network to join traditional financial institutions, foreign exchange market makers and liquidity providers into the payment network and build a payment gateway. Through the payment gateway, the flow of digital assets on the blockchain can be connected with the legal currency in reality, so that the legal currency can be converted into digital assets on the blockchain, which is convenient for subsequent payment and transfer. Through the network connector in the blockchain payment network, we can connect traditional market makers, remittance agencies, remittance agencies and other institutions, abandon the intermediate transaction link, and realize point-to-point fast and low-cost payment
Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain
Yu Kequn, director of the national information technology security research center, pointed out that the emergence of blockchain has brought people a lot of expectations for privacy exposure, data leakage, information tampering, network fraud and other issues. However, there are still many challenges in the security of blockchain
Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, use, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples
it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face
Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of the software and hardware related to the blockchain and a large number of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of the relevant security employees is scattered and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges

Why is the Internet era coming to an end and the blockchain era coming
Once the
blockchain develops, it will burst out more innovation. As the first proct of blockchain, bitcoin has proced many innovations since its birth. For example, small cross-border payment, recording transfer transactions between currencies, recording various stocks, registering housing property rights, recording program codes, etc.
the steam age liberates social proctivity, the electrical age enlivens social cooperation ability, the Internet age connects the world, and the blockchain era will let us truly realize freedom
Blockchain technology exchange
when blockchain technology is generally regarded as a technology in the market, the blockchain team of ant financial services technology laboratory gave a calm explanation: blockchain technology itself is not a special technology, but is integrated by many previous technologies, such as P2P network, many nodes, cryptography, It also includes something similar to consensus. So from this point of view, if we only use the previous technology, we will graally form the blockchain technology in the end
