I’m on the hunt for two distinct ECDSA keypairs where their derived addresses share the last 11 bytes

Basically birthday paradox with approx 2^44 attempts required to find a collision, so should be pretty computationally tractable

Anyone have resources to facilitate finding a set of these keypairs?

I think this is a really interesting challenge! It's like trying to find a needle in a haystack, but with the right tools and some luck, it should be doable. The fact that it only requires around 2^44 attempts is pretty cool - definitely within the realm of possibility for someone with the right skills. I don't have any specific resources off the top of my head, but I would suggest looking into some cryptographic forums or online communities where people might be able to help out. Good luck on your quest to find those keypairs!
