+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)<ref name="curve-order" /> as the secp256k1 secret key,
+as in the HD-Seed WIF application, and discard the trailing 32 bytes. Encode the secret
+key in Bech32 with the <code>nsec</code> human-readable part as specified by NIP-19.
