Decentralized Finance security vulnerabilities and prevention measures Recently, a security expert shared a DeFi security course with the community. The expert reviewed the major security incidents that the Web3 industry faced in the past year, discussed the reasons behind these incidents and how to avoid them, summarized common smart contract security vulnerabilities and preventive measures, and provided some security recommendations for project parties and users. Common types of DeFi vulnerabilities include flash loans, price manipulation, function permission issues, arbitrary external calls, fallback function issues, business logic vulnerabilities, private key leaks, and reentrancy attacks. This article focuses on three types: flash loans, price manipulation, and reentrancy attacks. Flash Loan Flash loans are an innovation in Decentralized Finance, but they are also exploited by hackers for attacks. Attackers borrow large amounts of funds through flash loans to manipulate prices or attack business logic. Developers need to consider whether the contract functionality will be compromised due to the influx of massive funds.

The Rise of Stablecoin Public Chains: Can Plasma and Stable Reshape the Global Payment Landscape? Stablecoins are gradually penetrating the traditional financial sector and retail market, with an increasingly rich array of application scenarios. To support this expansion trend, the support of new infrastructure has become particularly important. Recently, stablecoin-related chains such as Plasma and Stable have attracted market attention. These two projects aim to achieve faster, cheaper, and more scalable stablecoin transfer functionalities. Their core strategy is to absorb funds from the old network, which is less efficient but still holds a large amount of stablecoins. Although there are some differences between the two, there are more similarities, especially as both use USDT as a central hub. Plasma, built as a Bitcoin sidechain, inherits the security of Bitcoin while maintaining its own independent consensus mechanism. This system is specifically designed for high-frequency trading and fast confirmations, making it very suitable for quick transfers of USDT. Its most outstanding

The rise of NFTs provides new opportunities for businesses to build communities.

The week with the largest fluctuation since 2019 This week, the US stock market fluctuated like a roller coaster, although it basically closed flat for the week. There was a panic sell-off on Monday, a strong rebound on Tuesday, another drop on Wednesday, a bottom-fishing sentiment triggered by unemployment data on Thursday, and a continuation of the rebound on Friday, but with weakened momentum. In the past week, the stock market and the crypto market have been highly correlated. The media has been hotly discussing the U.S. recession and the unwinding of yen arbitrage trades, but this could be a "false proposition." The real panic was very short-lived, and there was no typical widespread sell-off seen during a crisis. After a sharp decline in the U.S. stock market on Monday, a peak-to-trough fluctuation of about 4.5% occurred, marking the largest magnitude since 2019. This fluctuation signifies both risks and opportunities. The sell-off during Monday's trading session may have been an overreaction, with the main reasons including: - Most U.S. economic data performed well, with only a few indicators supporting the recession argument. - The growth in corporate profits is stable, but the extent of the exceedance of expectations has not expanded. - Japan's continuous interest rate hikes are not possible.
