Odaily Planet Daily News According to the announcement of Cosmos Hub on the X platform, Proposal 914 has been approved by the community, which means that the v16 software upgrade will be implemented. Cosmos Hub stated that this upgrade will be implemented at block 20440500 (expected to be on May 15). It is reported that v6 includes new key features implemented by upgrading to SDK v 0.47: -IBC rate limit module: prevents a large inflow or outflow of IBC tokens in a short period of time, adding an extra layer of protection for IBC transfers; -ICA controller submodule: enables Hub users to use their Hub accounts to perform operations on other chains; -IBC fee middleware: creates IBC channels through in-protocol relay incentives.
