As the first "hybrid Layer2" protocol @build_on_bob, it combines the security of Bitcoin with the flexibility of Ethereum, aiming to seamlessly bring Bitcoin's value into DeFi and smart contract applications. It was officially announced by BGD Labs on June 10 that the BOB chain fully meets the technical standards for AAVE v3.3 deployment. This means it has passed AAVE's technical examination. However, the only downside is that the Chainlink oracle has not yet been integrated. Looking at the timeline, it was announced in January this year that Chainlink CCIP would be adopted as its cross-chain infrastructure, allowing for the secure cross-chain transfer of ERC-20 assets. In February, it integrated on-chain subscribable real-time data stream services, enabling developers to access external data feeds. Earlier this month, the CCIP was upgraded to further support cross-chain bridging of USDC. In the short term, while it can technically implement Pull-oracle + TWAP, in the long run, a standard oracle is still needed. Without the integration of an oracle, DeFi applications that require precise pricing and real-time liquidation functions will face significant limitations, and the platform's security will also decrease, making it susceptible to operational misjudgments. Most importantly, the overall ecosystem will be affected, and users and funds will be hesitant to participate. The AAVE team has also mentioned that they will not deploy without an oracle. We look forward to successful integration negotiations between BOB and Chainlink. Personally, I am quite optimistic about BOB. Although it currently operates as an ETH Rollup, supporting BTC liquidity and DeFi applications, the next phase of upgrades will be the main event, enabling BTC transfer between the Bitcoin and BOB networks in the form of POW + staking + ZK. At the same time, AAVE can also solve the trustless bridging of BTC through BOB, gradually increasing the penetration rate of BTC's DeFi ecosystem and entering the blue ocean market of BTC staking and lending.
