Bitcoin addresses are derived from the public key, which in turn derives from a private key. So you can already do what you propose, as long as your private keys satisfies the strength that Bitcoin requires.
- zeven7 9y agoThe math is not trivial enough to do with pen and paper.
- raulk 9y agoIf it was, how secure would Bitcoin be? How much more vulnerable would it make it to brute-force attacks? There's nothing stopping you from applying the key derivation algo step by step using a calculator, or an offline computer. It would make for an insightful, albeit time-consuming, experiment. https://bitcoin.stackexchange.com/a/29880 https://bitcoin.stackexchange.com/a/29880
- runeks 9y ago> If it was, how secure would Bitcoin be? It doesn’t matter how easy/simple it is to derive a public key from a private key. What matters is how easy it is to go in the opposite direction. As your link shows, it’s not that hard to do elliptic curve multiplication by hand, and there’s no need for it to be hard/complex.
