How many bit and what algorithm?

cracking algo is ecdsa multiplication, I obtained the ecdsa public key.. the OP message was signed with address 179sxfh6rw6bHSo5wVUhLP96k46QaEzVP

maybe large bitcoin collider can crack it  Grin

brute force attack cost:

8 top 10000 words ... 107 bits
8 top 50000 words ... 124 bits
8 top 100000 words ... 133 bits

But what I believe when we exclude certain words we can bruteforce the answer faster.

having the public key is not going to do you any good. and the "collider" thing is a joke, it can't help you if the private key is big enough. it is only searching the small area in the beginning of the numbers that are private keys.

as for brute forcing the answer you have to have some base to work with, i can't understand what your previous post even means!  the word is obviously the "jumble" of Satoshi Nakamoto but because there are repetitive characters in the name you can't find any kind of pattern in it. and it all seems like a random jumble not a meaningful key.

Ok, here's a 1BTC puzzle.

The question is the following:

WhyTheCombOfNatashaOtomoskiHas21Teeth?.txt

The solution is a 32 characters long plain-text (the private key).

Hint: 8 camel case english words, no special symbols

Happy puzzling!
