Middle -- general purpose index for use when picking middle hops in circuits. Bandwidth-weighted for use as middle relays. May exclude guards and/or exits depending on overall balance of resources on the network.
Formula: type: 'weighted', source: { type:'bw', require_flags: ['Valid'], 'bwfield' : ["RM", "mbw"] }, weight: { [ "!Exit", "!Guard" ] => "Wmm", [ "Exit", "Guard" ] => "Wbm", [ "Exit", "!Guard" ] => "Wem", [ "!Exit", "Guard" ] => "Wgm", }
Guard -- index for choosing guard relays. This index is not used directly when extending, but instead only for picking guard relays that the client will later connect to directly. Bandwidth-weighted for use as guard relays. May exclude guard+exit relays depending on resource balance.
type: 'weighted',
source: {
type:'bw',
require_flags: ['Valid', "Guard"],
bwfield : ["RM", "mbw"]
},
weight: {
[ "Exit", ] => "Weg",
}
HSDirV2 -- index for finding spots on the hsv2 directory ring.
Formula: type: 'rsa-id',
HSDirV3-early -- index for finding spots on the hsv3 directory ring for the earlier of the two "active" days. (The active days are today, and whichever other day is closest to the time at which the ENDIVE becomes active.)
Formula: type: 'ed-id' alg: SHA3-256, prefix: b"node-idx", suffix: (depends on shared-random and time period)
HSDirV3-late -- index for finding spots on the hsv3 directory ring for the later of the two "active" days.
Formula: as HSDirV3-early, but with a different suffix.
Self -- A virtual index that never appears in an ENDIVE. SNIPs with this index are unsigned, and occupy the entire index range. This index is used with bridges to represent each bridge's uniqueness.
Formula: none.
Exit0..ExitNNN -- Exits that can connect to all ports within a given PortClass 0 through NNN.
Formula:
type: 'weighted',
source: {
type:'bw',
; The second flag here depends on which portclass this is.
require_flags: [ 'Valid', "P@3" ],
bwfield : ["RM", "mbw"]
},
weight: {
[ "Guard", ] => "Wge",
}
