Odaily News In the roundtable session of "World Chaining: The Importance of Interoperability" at the 2024 Hong Kong SmartCon conference held by Chainlink, Chainlink co-founder Sergey Nazarov mentioned that ETFs are "compliant versions of crypto-wrapped assets" with characteristics such as accessibility and interoperability. Similarly, after the U.S. Treasury bonds were chained, such assets began to interact with DeFi, DEX, Lending protocols, etc., so that the chained assets of traditional assets can obtain the flexibility and corresponding benefits of various types of crypto assets. Therefore, the composability and consistency of different assets are crucial. This often relies on long-term technical accumulation and needs to meet user needs through rapid iteration. Compared with the traditional financial and DeFi fields, the application product teams of the former often lack the motivation to develop and build infrastructure; while for the latter, many applications will develop their own L2 networks to build their own infrastructure. In addition, the key factor of interoperability is liquidity. Traditional financial institutions, crypto exchanges, and crypto Dapp applications all need liquidity, and liquidity is the premise and foundation of interoperability requirements. Behind liquidity are the key challenges involved in the process of traditional financial institutions entering the DeFi field and other crypto worlds - identity verification (the traditional way is email) and data verification. Finally, if we want the liquidity interaction of different assets, then we need an interoperable system that meets the needs of both traditional institutions such as SBI and HSBC and crypto protocols such as Aave, which is even far greater than the needs of on-chain interoperable systems. The value of the oracle is thus deeply reflected.
