A wire of iron, driven by one token's market cap.It only goes one way, and it makes a noise when it moves.

Iron does not magnetise smoothly. Domain walls pin on defects and tear loose in bursts, so a smooth field produces a jerky response. Barkhausen heard this in 1919 with a coil and an amplifier. The field is the market cap. Every burst is recorded and nothing that flips ever flips back.

Hysteresis has 0 steps and ends at remanence 0.0000.
Every site has a threshold, which is the external field it would need to flip if nothing around it had moved. Those 4,096 thresholds were fixed at genesis and never change. Count how many of them sit at or below any given field and you get the thin line: the wire as 4,096 separate objects that never speak to each other. It is a real curve, computed from the seed, and it is drawn before anything has happened. The wire does not behave that way. A site that flips lifts each of its six neighbours by two units, which is often enough to push one of them over, which lifts six more. So sites go earlier than their own threshold says they should, dragged over by the ones that went first. The ink line is where the wire actually got to at each field, and it sits above and to the left of the thin one for that reason. The gap between the two lines is every site that only flipped because something next to it did.

├ about

Inside a piece of iron, regions pointing one way are separated from regions pointing the other by walls. Those walls catch on every flaw in the metal. Raise the field slowly and nothing happens for a while. Then a wall tears free, moves, and catches again somewhere else. The magnetisation goes up in a step, not a slope.

Barkhausen found this in 1919 by winding a coil around a wire, putting an amplifier on the coil, and listening. Every time a wall tore loose it induced a voltage, and the voltage made a click. A smoothly rising field produced a rush of clicks. It was the first direct evidence that magnetisation is not continuous, and it was heard before anyone could see it.

This wire is 4,096 sites in a cube. Each one is handed a random weakness at genesis and each one is pushed by its six neighbours. The external field is the market cap of one token. When the market cap rises past anything it has been, the field rises with it, and some of the wire tears loose.

When the market cap falls, the field falls and nothing happens at all. Not a small amount, nothing. A wall that has torn loose does not go back. The wire keeps the highest field it has ever seen and everything below that is recorded and then ignored.

The fraction of the wire that has flipped is called remanence. It is the amount of magnetisation left when the field goes away. On this site it has never decreased and it cannot, because the only operation the model permits is a site going up. Remanence is the only number here that means anything on its own.

There is no model that learns. The rule is four lines long, was published in 1993, and has no free parameters. The disorder is 2.16, which is the critical value for this model in three dimensions, and it is the one number that decides whether the wire crackles in bursts of every size or goes over all at once. It is also where the name comes from.

The wire is rebuildable. The seed is printed on the wire page. Anybody who runs the same seed gets the same 4,096 random fields in the same order, and feeding it the same sequence of market caps produces the same log, line for line. Nothing is stored here that could not be recomputed from those two things.

Nothing on this site is a forecast. The wire does not predict the market, it records it, and it records it in a form that cannot be edited afterwards. A rising market cap is written into the wire permanently. A falling one is written nowhere.

This is a slow object. Most of the time it does nothing, the status line says pinned, and the correct response to that is to close the tab. It is not built to be watched. It is built so that when you come back, what happened while you were gone is still there and still legible. When every site has flipped the wire is saturated, polling stops, and the last line of the log is the last line there will ever be.
