instrument

An instrument is not a stack of parts. An instrument is the discipline that forces several crude measurements to agree closely enough to be trusted. A sextant is a mirror, an arc, and a horizon, and none of those three is accurate on its own. The accuracy lives in the method that crosses them. meridian is the same kind of object. Its parts are ordinary. Its only real content is the reduction that turns four ordinary sightings into one position.

The chain underneath this site does not know meridian exists, and does not care. It agrees with itself about what is true every four hundred milliseconds and moves on. What this instrument does, and what any analytics layer does, is take that indifferent record and reduce it to something a person can sit with. The reduction is lossy. A fix is not the token. It is a representation of the token, accurate within a tolerance, useful for the judgments a person might want to make, and wrong in the small ways that all representations of moving things are wrong.

meridian reads from the chain through a single data provider, asked for server-side so that no part of the reading is performed in the open and no value is ever invented to fill a gap. it requests the price, the standing liquidity, the holder list, and the recent flow, and it crosses what comes back. when a value does not come back, it is shown as a dash, because a missing sighting is information and a fabricated one is a fault that would quietly poison every reading downstream of it. the live fix is refreshed every ten seconds. the figures look back across fourteen days.

the instrument is deliberately unremarkable underneath. there is no privileged feed and no secret access. anyone holding the same record with the same patience could take the same sights and cross them the same way. that is the point. the position was never hidden. it had simply never been crossed into a single coordinate before, and a thing is hard to see until someone draws the lines.
