As recently proposed by Core developer Sergio Lerner, is to hold onto the 1 megabyte limit, but speed up the block interval. If 1 megabyte blocks are found every five minutes instead of 10, that would allow for double the amount of transactions on the network while also decreasing confirmation times.
That seems so much smarter than a brute increase of block size. At least it would increase the speed and the volume.
Ethereum has 12s block time.
- Yet, I would not support either at this point.
Satoshi chose the 10 minute block interval as another careful, conservative limit. Sergio is an incredibly accomplished computer scientist, he would not suggest this change if he wasn't confident that Satoshi's concerns can be mitigated.
I'm not sure how much this helps though; it's two broad issues rolled into one, so it has the potential to just create a whole new set of arguments. However, if 95% of people agreed to do this tomorrow, and the technical aspects were convincing to me, I'd get on board.
It is "a whole new set of arguments" indeed. A categorical "no" to every hard fork is probably the best answer to invite more creativity. I like to see Bitcoin as the core of the 'onion' protected by a host of other solutions that can also serve for experiments.
