On Nov. 1st 2024 at 0:00 AM UTC I will post here a BTC P2PKH address (compressed) associated with an 80-bits secure private key.
The address owns 0.005 BTC (~340 $)
Starting from that time, at some point during the next 24 hours an outgoing transaction, containing unspent outputs from that address, will be broadcasted on the BTC network (public mempool, not Mara).
Let's see who breaks it. I only ask one thing if that happens: what method was used to break the key.
Together with the target address I will also provide the range of the search interval.
This will be in the form (just an example):
minKey = 0xf2e542b46066c4e6f91abc80000000000000000000185e689447431d74c5b133
maxKey = 0xf2e542b46066c4e6f91abcbfffffffffffffffffffd85e689447431d74c5b133
The Hamming length of the range will therefore be 80 contiguous bits, but they may start anywhere.
If your first instinct is to yell "this is not a 80-bits secure private key", please note this competition is NOT for you, do not expect a response from me.
Get your tools ready boys.
let someone be lucky) if a transaction takes place from that address and the public key is known...The case is 5 minutes. Even with my capabilities, it will be very fast to find him. I won't participate, just watch.(OK, not 5 minutes, but 10, sorry...)))
