Dragonfly Capital partner Haseeb stated on the X platform that despite the recent bad debt issues in Aave, he remains optimistic about the long-term development potential of DeFi. Haseeb pointed out that the DeFi industry characteristics evolve through failures, referencing the previous collapses of Terra, the failed Black Friday auctions of 2020, and the stETH de-pegging event, which made the sector more resilient after setbacks, similar to the historical logic of bank and thrift crises in traditional finance. He emphasized that the core of DeFi is risk aversion and system resilience; even if Aave incurs some bad debt, the existing equity of the protocol is sufficient to cover related losses. Haseeb believes that the intense discussions within the community around improvement plans are part of the industry's progress and that DeFi will not disappear due to a single event.

Bitcoin Core has released version v31.0, the core of this update focuses on introducing a "cluster transaction pool" design. This mechanism enables related transactions to be regrouped into clusters not exceeding 64 transactions or 101 KB, allowing nodes to assess the overall value of transaction groups more accurately according to the fee schedule, optimizing block packing efficiency and enhancing the logic of RBF and CPFP. Additionally, the new version significantly enhances privacy features, supporting users to conduct private broadcasts via Tor or I2P networks, effectively hiding the IP address and geographic location of the transaction initiator. Although ordinary transfer users are less affected, users of the Lightning Network or complex wallet services may perceive significant changes in transaction acceptance rules.
