TechFlow News — On November 27, in response to the "Compound mass liquidation incident," Sergey Nazarov, co-founder of decentralized oracle Chainlink, stated: "We predicted such attacks would happen a year ago, raised awareness about this attack vector at multiple public conferences, and publicly warned the developer community. In this incident, the Chainlink network remained unaffected due to its high degree of decentralization at both the node and data source levels, continuously providing accurate global market prices for assets. Even amid persistently high gas prices, DeFi smart contracts sourcing price feeds from the Chainlink oracle network were unaffected and continued receiving accurate price data, ensuring normal protocol operations. Over the past month, there have been multiple oracle-related attacks, highlighting that smart contract developers must prioritize oracle security. DeFi protocols relying on centralized oracles typically depend on only one or a few off-chain or decentralized exchanges for price data, exposing user funds to significant risks. Such attack incidents will likely drive more users toward DeFi protocols integrated with decentralized oracles to ensure oracle security and verifiability—similar to how users today are increasingly sensitive about private key security when using off-chain exchanges."
