There’s an interesting thing going on right now in Bitcoin land. The core developers have released a new version of the core Bitcoin software which includes a number of updates and the “segregated witness” approach to scaling the Bitcoin technology. This release won’t be “confirmed” until 95% of nodes adopt it. That 95% is a choice that the core developers made.
Right now “SegWit” is at roughly 1/3 of nodes (based on this tweet which I have no idea if its valid). The Internet is for fake news after all
