Analysis: Secondary attack on bZx points to need for thorough audit of DeFi smart contracts
2020-02-18 23:45
昨日去中心化金融(DeFi)贷款协议bZx再次被攻击。第一次攻击后,该平台被关闭并离线,开发人员试图修复合同约,保证恶意行为体无法执行另一次攻击。第二次攻击虽然不完全相同,但非常相似,似乎以太坊开发者还没有完全理解“Oracle问题”。第一次攻击让加密社区措手不及,因为闪电贷Flash Loan是DeFi平台提供的新产品。第二次攻击表明,需要对DeFi智能合约进行非常彻底的审计。bZx在两次攻击中都冻结了平台,这一事实表明,即使将其作为DeFi进行销售,但最终它是一个集中化平台,开发者可以使用“管理密钥”来关闭平台上的交易。(Bitcoinis)

Former Huaxing Capital investor: Investing in Circle seven years ago was a matter of luck, but its current market value of $20 billion is unexpected
Odaily News Lei Ming, who was once an investor in Huaxing New Economy Fund, invested in Circle in 2018. In his latest interview, he said that there was a certain amount of luck in investing in Circle seven years ago. At that time, Circle's main business was not stablecoins, and its valuation was only US$3 billion. Now the market value of US$20 billion is somewhat unexpected. The core judgment of investing in Circle is that blockchain technology can create very large commercial and social value in the future. The essence of finance is license ability, and Circle happened to be the one with the most complete licenses at that time. Circle was listed on the New York Stock Exchange last week, becoming the "first stock of global stablecoins". After two trading days, the stock price has risen by 247.42% from the issue price, with a market value of approximately US$24 billion. This IPO issuance of Circle ultimately raised US$1.1 billion and received more than 25 times oversubscription. (IPO Early Knowledge) Earlier news, Hong Kong-listed company Huaxing Capital disclosed that its Huaxing New Economy Fund had invested in Circle as early as 2018. The company will continue to be optimistic about the development of blockchain technology and actively explore the layout in the fields of Web3.0 and cryptocurrency assets.
