The CoW DAO released CIP-34 on Snapshot, a proposal that aims to determine whether the CoW DAO should test the new fee model in the next six months. The current proposal has a support rate of 99.99%. According to the proposal, the CoW protocol fee can only cover the gas cost, and the revenue will mainly come from the excess gas fee. To avoid relying on unintentional and unpredictable revenues, the CoW Protocol plans to develop reliable and sustainable revenue streams. The proposal identifies several fee models that may be implemented during the testing period, including offer improvement fees, transaction surplus fees, volume-based fees, fixed fees, etc. The core team plans to test different fee percentages, caps, and volume-based tiers during the beta period, while keeping a close eye on user metrics like market share, retention, and more. All fees will be accumulated into the CoW DAO and will bring benefits to the DAO in the ecosystem through future CIP.

Odaily Planet Daily News Conflux released the v2.3.0 hard fork upgrade announcement, saying that all nodes need to be upgraded before the Epoch number reaches 79,050,000 (estimated on September 7). The functions involved in this hard fork upgrade mainly include: 1. CIP-112 will be activated when the Epoch number reaches 79050000; 2. CIP-107 (introducing storage points, a destruction mechanism for storing collateral), CIP-118, and CIP-119 will be activated when the number of blocks reaches 188,900,000 (expected September 9); 3. CIP-113 will be enabled when the number of PoS blocks reaches 766,200 (expected on September 9). This upgrade will bring the following improvements: - Fixed a performance issue where some requests would never expire; - Added metrics for filter and pubsub API; - Refactored EVM code to improve readability. Conflux reminds that users need to upgrade their nodes before the Epoch number reaches 79050000, otherwise they will be incompatible with the upgraded Conflux protocol and cannot interact with the latest Conflux mainnet as expected (block synchronization, mining and other functions may be disabled) . If upgrading a node after the Epoch number reaches 79050000 requires deleting all data and resynchronizing from scratch, if you want to start a new node, you can download the latest Conflux v2.3.0 and run it directly.
