According to TechFlow, on July 16, Cosmos Hub published a post on the X platform stating that the community had previously voted to introduce the fee market module (Proposal No. 842) to Cosmos Hub, which has now been integrated. As part of the Gaia v18 version, it will provide an adaptive fee market and support ATOM destruction. The new fee market mechanism will only start adjusting fees when the block capacity usage exceeds 50%, that is, when the block usage exceeds 15 million Gas units, the fee will increase.
