Recently I took a look at bitcoin-dev mailing list, mostly to check reaction for Sergio Lerner's Segwit2MB proposal. The reaction was mostly negative.
Hey Sergio,
You appear to have ignored the last two years of Bitcoin hardfork
research and understanding, recycling instead BIP 102 from 2015. There
are many proposals which have pushed the state of hard fork research
much further since then, and you may wish to read some of the posts on
this mailing list listed at
https://bitcoinhardforkresearch.github.io/and make further edits based on what you learn.
Then I took a look at some of proposals listed
here, and found for example this:
It implements a series of block size steps, one every ~97 days, and ending at just under 31 MB in 2045 April, with each step increasing the maximum block size by 4.4%, allowing an overall growth of 17.7% per year. The initial size limit upon activation depends on when it is activated: for example, if in 2018 January, it would begin at ~356k; or if in 2024 June, it would begin at just over 1 MB.
So my question is: which blocksize related hardfork proposal has most support from core developers?
Also, I would like to remind that some of miners who are currently blocking segwit, explicitly stated, that they won't run segwit without blocksize increase.
