 of each of the above functions and values.
 
 The output keys of the `BL` scheme are also the output keys of the ARKG instance as a whole. 
-For example, the output key for EdDSA using Ed25519 or Ed448 is generated by invoking the required routines in RFC 8032 [section 5.1](https://www.rfc-editor.org/rfc/rfc8032#section-5.1) and [section 5.2](https://www.rfc-editor.org/rfc/rfc8032#section-5.2) respectively. Relatedly, for ECDSA over NIST curves the output key is generated by invoking the key generation routine specified in ANSI X9.62; and ECDH over NIST curves uses the key generation routine specified in [NIST SP 800-56A](https://csrc.nist.gov/pubs/sp/800/56/a/r3/final).
-These output keys enable use cases where any procedure that involves the private key and the blinding key generates an output that is independent of one involving only the private key.
-
+For example, if `BL-Blind-Public-Key` and `BL-Blind-Secret-Key` output keys for ECDSA over NIST P-256,
+then the ARKG instance will also output keys for ECDSA over NIST P-256.
 
 Instantiations MUST satisfy the following compatibility criteria:
