The fact that I can't prove my findings is driving me nuts and making me look like a liar.
Here is the address: 1EJvrRrgEAtAHx2dfVUh1NBresW1CJ9RHP
To prove a collision (finding 2 private keys to 1 public key) you just have to provide both private keys.
This is probably not what you are talking about? Because that would mean you are the first person to break SHA256..
But if you are talking about address collision (2 people randomly generating a private key to the same address)..
thats not a collision in the mathematical/cryptography sense.
Your "Address collision" (if you aren't lying; im not implying you do.. but its just very unlikely) probably comes from a bad bad (
really BAD!) Pseudo Random Number Generator.
May i ask how you computed the private key? Did you use a wallet (I hope you didn't.. because chances are very high that this wallet has a broken PRNG then)?
Or did you use a libary to create it? (In this case.. the RNG of the libary is broken and should be reported).
A few more information about HOW you generated that private key would be nice!
