Can someone explain me what will happen with blockchain size after 2MB blocks? Will it start becoming double as big as it is now, or just double as much transactions will happen at a time? Just wondering what will happen with full nodes in year 2020, because setting up full node today require average machine and a week of downloading, and chain doubles its size each year.
1mb blocks allow a max blockchain growth of ~52gb a year
over the last 8 years (mainly the very first 6 years) blocks were not full which is why right now 8 years of data is not ~420gb
EG before 2013 blocks were less than half filled
however because demand is at a constant 1mb full now. expect ATLEAST 52gb growth/year
-whereby it would be ~52gb a year if we just stay stuck at 1mb blocks.
-whereby it grows beyond 52gb/year depending on demand with more than 1mb blocks being allowed
