Followup to the QuasarCert field rename (commit 9b9bdda2). This sweeps
the remaining Ringtail identifiers and prose out of the consensus repo
entirely:
- Identifiers (Go code):
ringtailThreshold → coronaThreshold (import alias)
ringtailGroupKey → coronaGroupKey
ringtailSigners → coronaSigners
ringtailShares → coronaShares
ringtailGobEncode → coronaGobEncode
ringtailGobDecode → coronaGobDecode
decodeRingtailSig → decodeCoronaSig
EncodeRingtailSig → EncodeCoronaSig
RingtailRound1{,Data,State} → CoronaRound1{,Data,State}
RingtailGroupKey/Pub/Shares → Corona*
- File rename:
protocol/quasar/ringtail_gob.go → corona_gob.go
- PQMode constants:
PQModeRingtail → PQModeNasua
SigSchemeRingtailAcademic → SigSchemeNasua
"ringtail" / "ringtail-academic" string forms → "nasua"
- Prose & comments throughout the repo: "Ringtail" → "Corona" when
naming the production Ring-LWE library, "Nasua" when naming the
historical academic upstream (luxfi/nasua, formerly luxfi/ringtail).
Canonical Pulsar family taxonomy after this rename:
Nasua — academic R-LWE 2-round threshold sig (Boschini et al,
ePrint 2024/1113); trusted-dealer DKG; kept as historical
reference fork only. NOT for an open public chain.
Corona — production Ring-LWE threshold ML-DSA (Pedersen DKG over R_q
+ proactive resharing); `github.com/luxfi/corona`. The
Ring-LWE leg of QuasarCert.
Pulsar — production Module-LWE threshold ML-DSA (FIPS 204
byte-equal); `github.com/luxfi/pulsar`. The Module-LWE
leg of QuasarCert. Pure-PQ pair = Corona + Pulsar.
Wire-format unchanged. Tests: 28/28 packages green (-short suite,
quasar 29s, integration 58s, no regressions).
