real and proper full nodes?
well current rules are based on 0.11.2 and anything older then that is not a full node, but a relay node. seeing as they cannot verify information they have not got the rules for as some features have changed.
so imagine it this way
core has 2499 up to date full nodes
then if we look at the other nodes that have the 0.11.2 latest rules PLUS the desire for 2mb...
2mb imps have over 1000 (classic+bu+xt)(30%+)
now.. when the core fanboys upgrade to segwit. not all of those 2500 regular updaters will stick to being full archival mode versions.. we could see as many as 500+ prefer to be the pruned no witness nodes. thus diluting down the amounts of real uptodate nodes with the latest rules that fully validate the blockchain.
basically only 2000 nodes fully validating segwit transactions/blocks
