If I understand the scenario you're describing, you are effectively constructing an independent, second transaction that also pays the receiver, but using your own funds rather than the original sender's, for a smaller amount. The two transactions will not conflict, and both will go through. So not only will you have done nothing to prevent the original ...

So far as I know this isn't possible. The mnemonic phrase is hashed to get a seed number. Hashing algorithms are one-way algorithms. See BIP39 To create a binary seed from the mnemonic, we use the PBKDF2 function with a mnemonic sentence (in UTF-8 NFKD) used as the password and the string "mnemonic" + passphrase (again in UTF-8 NFKD) used as the ...

I encountered the same situation where I needed to dig further into the process of generating an Ethereum wallet. I have read through the material I could search for but none is giving me an answer I need to complete my programming task of creating a wallet. Here is a brief summary on what I have learnt so far: generate mnemonic generate a seed from ...

This is a property of elliptic curves. It is expected, and does not meaningfully impact security. Points on an elliptic curve have an X and Y coordinate. In the case of secp256k1, these coordinates must obey the equation y2 = x3 + 7 (mod p), where p = 2256 - 232 - 977. Whenever (x,y) is on the curve, (x,-y) is too (because y is squared, so its sign is ...
