Any info on who published this puzzle and what's their goal? Also, how would one go on about calculating those pvk decimal values and covert them to the private keys?
I don't know why but I'm smelling a big scam. Because a newbie that offer more than 12 000 to solve a following of numbers this is strange...
The OP is not offering anything
I have no idea about who created this transactions, I was just playing around with the bot and stumbled upon it.
After reviewing a bunch of pvks found by the bot I noticed that many of the addresses were on the same transaction, after checking closely I found those kind of sequence patterns.
Looks tempting to crack

One thing I noticed:
The first address in the transaction is tagged on blockchain.info with "1st Bitcoin Address Compressed".
So probably this transaction was done by the Bitcoin devs? or even... satoshi?
