10:38 < gmaxwell> I wonder if it would be acceptable to limit the set of mutually authenticated peers of a node to some small number like 128.
10:41 < sipa> wrong channel?
10:41 < gmaxwell> want to discuss soem crypto here first.
10:44 < gmaxwell> Consider the protocol where a host has a collection of authed parties with pubkeys P1,P2,P3,P4... Party P3 connects, host picks a random x, publishes Ps = xG, and xP1, xP2, xP3, xP4... so on.  This data is indistinguishable from any other candidate set of P_n, to someone without a DDH oracle.   Then the responding peer replies with a tracable ring signature with respect to Ps,  he knows xP3,s discrete
10:44 < gmaxwell> log with respect to Ps (thats his private key).  He provides some tracing value with respect to a nums generator that the host selects and changes once per day (or whatever).  The tracing lets the host tell if the same peer connected multiple times in that interval.
10:45 < gmaxwell> assuming no reuse during the tracing interval.. I think neighter party learns anything about the other's identity beyond it being in the allowed list. nor does anyone learn anything else about the other pubkeys in that set.
10:46 < gmaxwell> An actively malicious server could dummy out most of the set to remove your anonymity set; so this is something of a semi-honest assumption.

13:40 < waxwing> does anyone know anything about generating coverage stats for github? i've just taken a look at coveralls.io but it doesn't look like it supports branches(?)
13:41 < waxwing> i say 'coverage stats for github', i guess i really mean via travis, i guess you get the idea
13:43 < waxwing> ouch, sorry, wrong channel :)
