The Canyon upgrade contains the Shapella upgrade from L1 and some minor protocol fixes. The Canyon upgrade uses a L2 block-timestamp activation-rule, and is specified in both the rollup-node (canyon_time) and execution engine (config.canyonTime). Shanghai time in the execution engine should be set to the same time as the Canyon time.
