Here is the post for archival purposes Author RHavar Content AbstractstrongBlock weight limit voting would move the responsibility of deciding the block weight limit to miners . This represents quite a radical and risky change for bitcoin , but could potentially end years of bike shedding . This proposal tries to protect minority miners and preserve decentralization by requiring a super majority of miners to agree on any changes . DescriptionstrongBlock weight voting would be conditional upon segwit activation , and a require ahard fork to be sanely implemented . There appears to be numerous reasonably safeways to do such a hard fork e . g . first soft fork to miners who support the hard forkbut that is out of scope for this . Block weight limit voting would add a new field to the block header idealweightlimit au 32 that represents the ideal block weight limit in KiB that the miner of that block would like to see . If more than 95 % of all blocks during a retargeting period are voting for a new weight limitthat represents an increase or decrease from the current weight limit , the newblock weight limit would be moved to where 95 % support exists . As a safety feature , the block weight limit change would be capped at a hard 5 % change per retarget period . QAstrongWhy is it block weight , and not block size ? blockquoteBlock weight is what segwit uses , and a better limit in general . It also wouldn ' t bemuch of a compromise proposal if tried to exclude segwit . Why don ' t miners vote for block weight by making blocks of that size ? blockquoteBecause this would severely disadvantage a miner who wants to have both smaller blocks but also maximize their income . Why is there a 95 % threshold , and not 51 % or somewhere in between ? blockquoteBecause there exists inherent conflicts of interests between miners and bitcoin users , 95 % is a very conservative number that errs on the side of caution and helps protectminority powers against more centralized mining . This number is also well established in soft forks , as miner preference is also only considered a rough proxy for the bitcoin economy at large , it makes sense to be veryconservative . Thoughts ? Support ? Does it have what it takes to end the great block size debates for once and for all ? strong
