Thank you, Andrew, yes that helped. You helped. The internet does not help, it offers help sites maybe. Anyways, the Bitcoint FAQ site only explained me it was a public ledger. Hahaha. So? And then there was you and you took the time to explain it to me .. my special thanks to you. Also thanks to Neil's link I have got a rough idea now what you are talking about. What is not quite clear to me yet - and I have the same problem in colour discussions when I don't know whether they speak of additive mixing or subtractive mixing - when 51% agree to a falsified version as you say, is it not that the falsified version is thereby verified and not falsified? Things get so easily twisted, not even on purpose, what does honesty mean in this context?
