Monad's mainnet just proved out a real efficiency gain — a block-pinned test reproduced that steep 8,100-to-100 step-down, basically a 98% cost cut for storing data together. The cold charge coming back at slot 128 shows the mechanism resets predictably, not just a one-off fluke. Cheaper batch storage like this is the kind of unglamorous upgrade that actually moves the needle for builders shipping on-chain.
