01 A promise from Feb 17, 2021

“There will definitely be a MarsCoin!”

He never built it, so we did — and we gave it something to do. $MARS buys compute on a planetary network that runs on the real Mars: NASA's laser-altimeter elevation, the IAU's 2,049 named landmarks, and a live Mars clock.

02 The network

MARS IS TOO VAST
FOR ONE MACHINE.

We turn distributed compute into a planetary instrument.

Every contributed cycle resolves another piece of Mars: its terrain, its hazards, where a habitat could stand, what a rover could cross, how much sun a panel would catch. The output is a public model that gets sharper every day.

How the protocol works
03 The origin

IT STARTED AS A
THROWAWAY REPLY.

February 2021. Musk is publicly worried about Dogecoin whale concentration. A follower suggests starting fresh. CZ names it. Musk promises it. Then nothing — for five years the most famous unlaunched coin in crypto just sat there.

Elon Musk · @elonmusk · Feb 15, 2021
“If major Dogecoin holders sell most of their coins, it will get my full support. Too much concentration is the only real issue imo.”

“I will literally pay actual $ if they just void their accounts”

Suggests a fresh coin instead — offer it to the small holders, skip enriching the whales, and make it “the currency of the Earth.”

04 Why it has to exist

MARS CANNOT SHARE
OUR LEDGER.

The promise was the easy part. The reason came later, when Musk was asked whether Dogecoin could simply be the currency of Mars. His answer was that it could not — not for any reason of policy, but because of the speed of light.

Mars would need its own local currency. Light takes minutes to cross the gap, so anything that depends on staying tightly in step with Earth cannot work there. Some form of cryptocurrency on Mars is likely — but a standalone one, decided by the people living there.

Two books, not one

A wallet holds an Earth balance and a Mars balance. There is no single synced number, because physics does not permit one.

Local settles instantly

Compute, missions and mining all clear on the Mars book the moment they happen. The colony never waits on Earth for anything.

Crossing costs real time

Move value between the books and it travels at light speed — leaving one side at once, arriving on the other minutes later. It cannot be recalled.

AND THE MONEY ITSELF
BECOMES MASS AND ENERGY.

Asked what the currency would eventually be, his answer was that dollars would not be — it would be mass and energy. So that is what this colony's reserves are measured in, and they are computed rather than declared: every kilowatt-hour and every tonne below comes from a verified job on real NASA data. The base can only grow when someone resolves more of the planet.

EXPLORE THE
REAL PLANET.

Not a mock-up. Click anywhere on Mars and read its true elevation from NASA's MOLA laser altimeter, its surface slope, the local solar time at that longitude, and which of the 2,049 IAU-approved landmarks you are standing in.
