Hey all,

This is a genuine competition.

My friend and I have a bet.

He says that because Bitcoin has been around so long now, it should be possible to crowd source a private key for almost any specific public address as he reckons there will now be databases out there with trillions upon trillions of matched key pairs. I say this is rubbish and it cannot be done.

So, here are 100 addresses. They are all zero balance, sorry.

If anyone can provide a correct private key for any of these addresses, I will give you 0.1 btc.

I don't think it can be done and I'm putting my money where my mouth is.

Prove me wrong haha!

If you do, then you can just post the private key in here for me to check.

Good luck!

I am doing a school project about Bitcoin and more specifically point addition on the Elliptic Curve. I am very new to all this so please forgive my mistakes.

I have been reading that when adding points together the result can go "outside of the bounds before intersecting a third point" as in this image.



This is fascinating but also a little confusing and I would like to know more.

So my questions are:

1. Is it possible to know when the point addition process has gone outside of the field?

And

2. Is there a way (like a Python script or something) that I could use to add 2 points and it would tell me if the result went outside of the field?

I know that the result of the addition is still a valid point on the curve, but I would love to know if it passed out of bounds first.

This would be fantastic for my project to show others how this works.

I hope that made sense and thanks in advance for your help.

Hey guys,

Looking to see if anyone can tell me how to modify the Vanitygen code so that it will start searching at the same point every time and not jump around to another random search position.

Thanks in advance )
