Actually they do allow you. You're just unable of spending the genesis block's coinbase UTXO. The address has 18.52264025 spendable bitcoins sitting in the dust. Quite huge amount if we're talking about crackable puzzles.

This is what I was asking too. It turns out that some people intentionally left some BTC to be found from individuals. It's probably a way to test the system's security. The money is the incentive for their work.

Here's another puzzle: Bitcoin puzzle transaction ~32 BTC prize to who solves it

Hello, I have only recently understood all this (VS, BitCrack and now this kangaroo)

I understand that this is the compressed pubKey, but it gives me another address (different from the one that starts with 17) and that confuses me a bit.

Can you help me understand what the correct inputs should be in the kangaroo?
Something like
"
124bff742a76f92fa3a76f8f6552f
1FFFFFFFFFFFFFFFFFFFFF
0213ee32399b1441d0c8cf7caf6d10641b30d280fe1b59fcaa09eb0326cad5cb6f "

If I put it to work, would I get a key that I can directly use, or would I get a key that I have to "Share" with someone to finish "finishing" the job?

I sent you a message a couple of days ago.

Thanks

no wonder why that user wants to share the half amount to anyone who can cracked the address successfully.  What a very lazy hacker! Lol
I thought this is a contest like what sometimes happens here but after reading then text above seems not.  But i was wondering where did he get those codes.? Or that's what he only knows how to hack, i mean the basics? Because you know obviously he's not the owner.. Lmao

It is a key that has been artificially reduced to between 1 and 2^120-1.

P.S. Stop sending me messages every time you make a post.
