Starting a new thread to pursue Greg's suggestion to agree upon definitions for "authentication" and "anonymity" to help the WG address the charter question now under deliberation.<br><br>
Below are a few definitions copied verbatim from RFC 4949 (<a href="https://tools.ietf.org/html/rfc4949"> https://tools.ietf.org/html/rfc4949</a>) as a starting point for WG discussion of these and other possible sources/definitions.<br><br>

To hide an<o:p></o:p></pre><pre> entity's real name, an alias may be used;<o:p></o:p></pre><pre>for example, a financial<o:p></o:p></pre><pre> institution may assign account numbers.<o:p></o:p></pre><pre>Parties to transactions<o:p></o:p></pre><pre> can thus remain relatively anonymous, but<o:p></o:p></pre><pre>can also accept the<o:p></o:p></pre><pre> transactions as legitimate.
