Keeper is a zmvm guest program that runs the block transition. It relies on the zkvm maker implementing `getInput`. For now, we only provide a single implementation for the 'ziren' VM. Why keeper? In the _Mass Effect_ lore, the keepers are animals (?) who maintain the citadel. Nothing is known from them, and attempts at tampering with them have failed, as they self-destruct upon inquiry. They have a secret, nefarious purpose that is only revealed later in the game series, don't want any spoilers so I didn't dig deeper. All in all, a good metaphor for zkvms. --------- Co-authored-by: weilzkm <140377101+weilzkm@users.noreply.github.com> Co-authored-by: Felix Lange <fjl@twurst.com>
