Hi Adam, Commenting on your question: > With segWit vs pre-SegWit didn't wallets just select and standardize > on a different HD derivation path? > > Is there something else needed than a Schnorr derivation path? The general accepted practice (defined in BIP43) is to define a dedicated purpose

Hi, Background == Had a discussion last night in Bitcoin Core IRC with Peter Wuille on different topics regarding key derivations, security, key tweaks in context of Schnorr signatures & Taproot. Would like to share some action points and plans that emerged from there: 1. There is a
