MsgValsetConfirm this is the message sent by the validators when they wish to submit their signatures over the validator set at a given block height. A validator must first call MsgSetEthAddress to set their Ethereum address to be used for signing. Then someone (anyone) must make a ValsetRequest the request is essentially a messaging mechanism to determine which block all validators should submit signatures over. Finally validators sign the validator set, powers, and Ethereum addresses of the entire validator set at the height of a ValsetRequest and submit that signature with this message.
