ja habe erst 150 iotas verschickt dann 3g iotas

und wenn ich eine neue Transaktion machen will sagt er mir das die vorherigen erst bestätigt werden müssen.

Das ist nicht gut, wenn die IOTA auf einer Adresse lagen Tongue

And here are the whys:

It all has to do with multi-spending. Which is spending more than once from the same address. The problem here is that IOTA uses one-time signatures. After spending addresses are not supposed to be used any more because in the process of spending a random 50% of the private key to the address gets exposed. This in itself is not a problem, any funds arriving after a single spend are still pretty safe. Breaking the other 50% of the key is still a daunting task.

But when a second spend happens on the same address a new random 50% of the private key for that address gets exposed. Theoretically, statistics will tell you that now 75% of the private key is exposed. But here is the difference between theory and practice. Since it is a *random* 50% of the key that gets exposed, you could be unlucky enough that both 50% exposures only have a 10% overlap. In which case a whopping 90% of your key is exposed already! In which case your private key is toast and broken relatively easy.

So in short: 2 or more spends from the same address is VERY BAD!

f*** was heisst das jetzt ?? ich fang an zu schwitzen.. dieser coin raubt mir den letzten nerv....
