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.
