Jae Kwon, the founder of Cosmos, has called for a chain split of the Cosmos blockchain. A chain split is a hard fork that results in two separate blockchains. Kwon is calling for the chain split to reduce Cosmos's native token ATOM's inflation to 10%. The call for a chain split comes after the Cosmos community voted to reduce ATOM's inflation to 7% in October. Kwon believes that this is not enough and that a 10% inflation rate is necessary to ensure Cosmos's long-term sustainability. The Cosmos community is now debating whether or not to approve Kwon's proposal for a chain split.
