Wall Street's interest in moving trillions of dollars onto blockchain technology is being stymied by security concerns, particularly from AI-enhanced hackers, according to Ronghui Gu, CEO of CertiK, a blockchain security firm. In April 2023, the decentralized finance (DeFi) sector experienced its worst month in four years, with hacks reported on nearly every day. High-profile incidents, such as the $1.46 billion breach of Bybit and significant losses from Drift Protocol and Kelp Dao, underline the systemic vulnerabilities in DeFi. Gu emphasized that traditional financial institutions are eager to embrace the efficiency of blockchain but are deterred by the risks associated with AI attacks, smart contract flaws, and cross-chain bridge vulnerabilities. The disparity in resources between attackers, who can afford to invest heavily in their exploits, and defenders, who operate under tight budgets, exacerbates the problem. As hackers continue to refine their techniques, the trend of frequent attacks is likely to persist, complicating the transition of traditional finance (TradFi) to on-chain assets.
