The Risk Protocol · MMXXVIMore than two thousand years ago, a hand-cranked bronze machine made the sky predictable. It is the oldest known analogue computer, and it is the inspiration for the new mark of The Risk Protocol.
More than 2,100 years apart
Around Easter 1900, Captain Dimitrios Kondos and his crew of sponge divers from the island of Symi stopped at Antikythera, a small island between Crete and the Peloponnese, to wait for better winds. The diver Elias Stadiatis went down more than forty metres and came back saying he had seen a pile of decaying bodies and horses on the seabed. What he had seen were statues, the cargo of a ship that sank in the first century BC.
With the Greek navy in support, the divers brought up bronze and marble statues through the winter and into 1901, among them the bronze Youth of Antikythera. One diver, Giorgos Kritikos, died of decompression sickness and two more were paralysed, and the work stopped in September 1901. Among the finds, and drawing little attention, were a few lumps of corroded bronze and wood.
In 1902, Spyridon Stais, the politician who as minister of education had overseen the salvage, was visiting the National Archaeological Museum when he noticed the traces of gearwork on two of those lumps. It was the first sign that the sea had given back a machine.
The historian of science Derek de Solla Price took up the puzzle in 1951. Twenty years later, the Greek nuclear physicist Charalampos Karakalos made gamma-ray and X-ray images of the fragments for him, and in 1974 Price published what they showed: a train of interlocking gears unlike anything else known from the ancient world.
The Antikythera Mechanism Research Project, an international team led by Mike Edmunds of Cardiff University, used X-ray tomography and high-resolution surface imaging to study the 82 surviving fragments. Faint inscriptions that once covered the case could now be read, among them what appears to be an instruction manual on its back door.
A team at University College London, with Tony Freeth as lead author, published a new model of the entire machine. The fragments themselves are kept today in the National Archaeological Museum in Athens.

The inscription gives the cycles of the five planets known at the time: how long each takes to return to the same place relative to the Sun.
02, 03 Star calendar. Above and below the dial, a star calendar called a parapegma lists the risings and settings of stars through the year, keyed to the zodiac. The dial between them showed the Sun, the Moon and the planets.
04 Month names. The upper spiral is a calendar of 235 months over nineteen years, with the name of each month in its cell.
05 Eclipse notes. Inscriptions around the two dials describe the character of each eclipse the lower spiral predicts.
06 Eclipse glyphs. The lower spiral counts the 223 months of the Saros cycle, about eighteen years, and glyphs in its cells mark the months with an eclipse.
07 to 09 The user's manual. The back cover explained the machine: a description of the display on the front, the structure of the calendar, and the cycles of the Moon and the Sun.
Pointers for the Sun and the Moon moved around the signs of the Greek zodiac and a ring of day marks. A small ball, half white and half black, turned to show the phase of the Moon, and a pin-and-slot pair of gears made the Moon speed up and slow down across the month, the uneven motion that the astronomer Hipparchus described.
The machine sat in a wooden case about the size of a shoebox and was driven by a small hand crank, now lost. The crank turned the largest gear, a four-spoked wheel about thirteen centimetres across with an estimated 223 teeth, and that one wheel drove every other gear. Its teeth were small triangles, just under two millimetres apart, probably cut by hand.
One spiral dial kept a nineteen-year calendar, with a smaller dial for the four-year cycle of athletic games that included the Olympics. A second spiral counted the 223 months of the Saros cycle, and glyphs in about fifty of its cells marked the eclipses it predicted.
Nothing of comparable complexity is known for more than a thousand years afterwards, until the astronomical clocks of fourteenth-century Europe.
The machine took a sky too tangled to follow by eye and made it readable, measurable and predictable. The Risk Protocol is building the same kind of machine for risk in crypto.
A single crank drove every dial on the machine. The Risk Protocol works the same way, with one Risk Engine powering SMART Tokens, Risk Prediction Markets and Risk Intelligence.
The machine turned cycles too long to track into positions, phases and eclipse warnings that anyone could read. We turn crypto risk into something people can hold, trade and forecast.
The gears sat inside the case, and what people saw were the dials. A layer is exactly that: machinery underneath that makes the surface make sense. It is why we call what we are building the Risk Layer of Crypto.
A single continuous ring carries every tooth and anchors every spoke. It stands for the layer itself: one piece of infrastructure that everything we build runs through.
On the original, a ball half white and half black turned to show the phase of the Moon. Ours shows risk split into two halves that always add back up to the whole, each held by whoever wants that side: stable or amplified, up or down, yes or no.
All three spokes meet at a single hub, the Risk Engine. Nothing on the wheel turns on its own; every product draws its motion from the same centre.
The original's front dial carried a ring of day marks and the signs of the zodiac. Ours carries 365 day marks, one for every day of the year in a market that never closes, engraved on a black face.
The wheel is anodised in the brand gradient, from cyan to violet, with a machined highlight along its edges. Special editions come in platinum, and in bronze, the metal of the original.
The rim carries 223 teeth, the best estimate for the great wheel that drove the original and the number of lunar months in the Saros eclipse cycle. Each tooth is a triangle, the profile of the original's hand-cut teeth.
A hairline seam divides the halves. It is the split itself, the Split Mechanism for Asset Risk-Tokenisation that gives SMART Tokens their name. A collar holds both halves in one frame, because together they always add back up to the whole.
The original wheel has four straight spokes. Ours has three, one for each product on the Risk Engine: SMART Tokens, Risk Prediction Markets and Risk Intelligence. They are swept like turbine blades, so the wheel seems to turn even at rest.
From about 200 pixels up, the mark appears in full metal, with its engraved zodiac ring, the bronze gear behind the wheel and the split moon.
Launch appSMART Tokens, Risk Prediction Markets and Risk Intelligence on one Risk Engine.
Every flat colour in the mark comes from the brand palette. The metal finishes add lighter and darker tints of the same hues to give the metal its sheen.
The wordmark is set in Marcellus, a flared serif drawn from classic Roman inscription letters. The ship that carried the mechanism sank in the Roman era, and the machine itself was engraved with Greek capitals, so the name is cut the same way: in capitals, spaced wide, made to last. Roboto and Roboto Mono carry everything else.
