+
+Application number: 86'
+
+The application number is the sum of the alphabetical positions of the letters in Nostr (n=14 + o=15 + s=19 + t=20 + r=18) to avoid the confusion with NIP06.
+
+The derivation path format is: <code>m/83696968'/86'/{identity}'/{account}'</code>
+
+Uses the entropy as a Nostr private key.
+
+Identity index <code>0'</code> is reserved for future protocol use.
+Account index <code>0'</code> is reserved across all identities for key management operations.
+Usable keys start at <code>identity >= 1'</code> and <code>account >= 1'</code>.
+
+The resulting 32-byte private key is Bech32 encoded as an <code>nsec</code> per NIP19.
