Deterministic Entropy From BIP32 Keychains

BIP 85, Deterministic Entropy From BIP32 Keychains. ''"One Seed to rule them all,'' ''One Key to find them,'' ''One Path to bring them all,'' ''And in cryptography bind them."'' It is not possible to maintain one single (mnemonic) seed backup for all keychains used across various wallets because there are a variety of incompatible standards.
