So what your saying is a single private key could have plenty of public hashes but those public hashes cant be reduced back to their originals based on themselves therefore as long as you maintain full control of that original private key keep it secure use your 12 word phrase to restore the key anywhere and it would be literally impossible for anybody other than yourself to gain access to that private key. As long as you created it originally. Thats why bitcoin is beautiful. Im not a mathematician by any standard, but i trust in math more than i could any religion. Thanks for breaking this down for me again its been a long time since i first looked into what makes your kes secure and insecure. Much love.
