IRCScore

IRCScore

IRCScore is a dimension of the Community Reputation Score (CRS) in Stellar. It measures how active and consistent you are on korin.pink IRC.

Formula

IRCScore = activity × consistency × channelQuality   (cap = 6, weight = 1.0)

activity       = log1p(messageCount)   / log1p(50)
consistency    = presenceSeconds / windowDurationSeconds
channelQuality = log1p(channelCount)   / log1p(5)

All three factors are in [0, 1]. Their product gives a natural score between 0 and 1 before scaling to the cap of 6.

Factor	What it measures	Saturates at
activity	Messages sent in the flush window (log-scaled)	~50 msgs
consistency	Fraction of the window you were online	100% uptime
channelQuality	Number of unique channels you were active in (log)	~5 channels

Log-scaling on messages and channels means the marginal score gain from a 500-message flood is nearly zero — quality of presence matters more than volume.

How it’s computed

The irc-bridge daemon on korin.pink tracks per-nick: presenceMs, messageCount, and channels. It flushes this data to the korin API every 60 seconds (FLUSH_INTERVAL_MS).

Stellar polls GET /irc/metrics every 5 minutes and caches the result. When your CRS is read (on profile load, leaderboard, etc.), getIrcScore(nick) is called against the cached metrics — no extra DB query.

The score reflects the most recent completed flush window at time of read. It’s stale by at most one poll interval (5 minutes by default).

How to earn IRCScore

1. Register a nick on irc.korin.pink (connecting guide)
2. Link it to your Stellar account via PUT /api/users/:id/irc-nick
3. Show up. Consistent presence matters more than high message volume.

Absence of an IRC nick earns a score of 0 — IRC participation is optional and its absence doesn’t penalise other CRS dimensions.

Nick linking

PUT /api/users/:id/irc-nick
Content-Type: application/json
{ "ircNick": "your_nick" }

• The nick must match your registered Ergo username exactly (case-insensitive on Ergo’s side, stored as-entered on Stellar’s side).
• Only one Stellar account can claim a given nick. Conflicts return 409 Conflict.
• To unlink, send { "ircNick": null }.
• Admins can update any user’s nick; regular users can only update their own.
