According to Techub News, Cosmos Hub tweeted that the community had previously voted to introduce the fee market module (Proposal No. 842) to Cosmos Hub, and the integration has now been completed. As part of the Gaia v18 version, it will provide an adaptive fee market and also support ATOM destruction. The new fee market mechanism will only start adjusting fees when the block capacity usage exceeds 50%. In short, the fee will only increase when the block usage exceeds 15 million Gas units.
