@Arachnid unless I’m misunderstanding something this change would result in what is today being a full block becoming a block that is only partially full (due to the reduction in gas cost for storage) and as a result means that for a given block gas limit a block after this proposal was implemented will have more transactions, hence take longer to transfer and longer to validate.
this change reduces the overcharging of gas for no-op storage writes down to something resembling the actual costs
which is my point. If 8 million gas worth of transactions today becomes (for example) 4 million gas worth of transactions after this proposal is implemented it has the same network impact as doubling the block gas limit without implementing this proposal. I doubt that anyone would consider the latter to be a sensible idea.
Again, I’m all for this proposal and have railed against incorrect gas costs for storage in the past. I just worry that it might have an impact on the network and was wondering if that had been examined/quantified.
