+Application number: 128002'
+
+The derivation path format is: <code>m/83696968'/128002'/{identity}'/{account_index}'</code>
+
+Each <code>identity</code> is an independent, unlinkable Nostr key namespace, and each <code>account_index</code> is a distinct key within that identity.
+
+Identity index <code>0'</code> and account index <code>0'</code> are reserved for future key-management use, such as proof-of-linkage between an identity's keys, key rotation, and revocation. Their semantics are out of scope for this BIP and may be specified by a future NIP. Usable signing keys therefore start at <code>identity >= 1'</code> and <code>account_index >= 1'</code>.
+
+The standard application of BIP-85 produces 64 bytes of entropy. Take the first 32 bytes (the 256 most significant bits) as the Nostr private key and discard the trailing 32 bytes, as in the HEX application. This 32-byte private key is then Bech32 encoded as an <code>nsec</code> per NIP19.
