This UMIP proposes to update the OptimisticAsserter to include a new parameter in the AssertionMade event. The objective of the update is to enhance the functionality of the OptimisticAsserter by adding this new parameter, allowing it to transmit more information about the assertions being made. The process of redeploying the OptimisticAsserter will involve updating its code and re-publishing it to the networks listed below.
