Last time we polled the community to determine the accepted definition of "successful double spend,"
the results were as follows:
35 voters is not the community determining the definition.
i can get 35 people to determine that superman is real and that kryptonite can be bought for $12 at a 7-11
edit:
a double spend:
imagine a bank note, you give it to a cashier. and buy a ice-tea. the cashier in a moment of panic accidently gives you back that whole banknote back as change. you then buy a cake from another shop. at the end of the day the ice-tea cashier is missing a bank note. and is at a loss. because there is only one bank note that has been spent twice
human error counterfeit:
however. what most people perceive as a bitcoin double spend is where the sender sends 2 exact same bank notes (copies) one to a ice-tea shop and one to a cake shop. where only 1 of those recipient confirms its a legit bank note which thy can re-use later, and the other realises they got a dud counterfeit that will never be confirmed as a real bank note that they can never then spend later.
so its not a double spend.. its a human error to not confirm counterfeits
