We have been reminded, by the pretention nodes, that there is always a risk of a largeblock being orphaned, especially the first one, then the next one that is larger, and so on. Not only due to timing, verification of the block, the technical stuff, but also the willingness of others to build on it. In business, the risk transforms directly to cost.

After a block of 2MB for example, the risk is reduced for blocks up to and including that exact size. We will therefore in the future see step increases in the blocksize, with retraction in between due to the varying demand. The typical leg up, stability, another leg up pattern, all market based.
