abstract class Instigator<out S : ContractState, out T : ContractState, out M>(val originalState: StateAndRef<S>, val modification: M, val progressTracker: ProgressTracker = Instigator.tracker()) : FlowLogic<StateAndRef<T>>
The Instigator assembles the transaction for state replacement and sends out change proposals to all participants (Acceptor) of that state. If participants agree to the proposed change, they each sign the transaction. Finally, Instigator sends the transaction containing all participants' signatures to the notary for signature, and then back to each participant so they can record it and use the new updated state for future transactions.
