Or am i wrong?! It works for every number, because it is "modulo n-value".Code: +---+------------------------------------------------------------------+ Title: Re: Multiplication number to get half public key "Magic Number" Post by: ElDalmatino on January 14, 2024, 04:31:10 PM Multiply by this to have your public key divided by 2, 4, 8: Code: Target/2 = 7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a1 Here is a script made by @mc, Code: import bitcoin The script above will divide the target by 2, 3, 4, 5, ..., 32. You can set any range you want. Ok great but lets say i take the public key of 11 = 03774ae7f858a9411e5ef4246b70c65aac5649980be5c17891bbec17895da008cb i get on 11 the pubkey of 1 and on 22 the "i call it ground" but what are the pubkeys between ? Itīs like i take it and do my public key and subtract 1 ! till i get a target pubkey lets say 0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798, whould be way faster with secp256k1 as ice, or do i miss something.

I read and read but donīt understand it, if i have a a pubkey and wanna reduce the range, it will come to a point where the dez value is odd and the whole thing go in a "never ending" story. But i know there is a way, because you all talk about it in different posts. Maybe somebody explain it, in one easy to understand way. |
