01 / THE NARRATIVE

Before the
memes had names.

Before the dogs. Before the frogs. There was Sirius.

In 2009, Satoshi's right-hand dev "sirius" logged into Bitcoin's earliest forum with a ginger cat as his avatar.

That cat has been sitting on the blockchain's origin story for 15 years.

It's his turn now.

02 / THE SATOSHI CONNECTION

The assignment
from 2009.

bitcointalk — private message
2009 email from Satoshi Nakamoto to sirius, asking for help building a website and FAQ

Satoshi asked Sirius for a website.

It's right there in the released 2009 emails. Satoshi admitted writing wasn't his strong suit and handed the job to the cat's owner: build the site, and write a FAQ. Sirius said yes and started that same day.

15 years later, we finished the assignment.

THE WEBSITE YOU'RE ON IT.
THE FAQ SCROLL DOWN.

Run by the cat, exactly as ordered.

FUN FACT / 2009

01

The word
was in the room.

"Cryptocurrency" was first floated in this very email thread. The cat was in the room when the word was born.

03 / THE FAQ

FREQUENTLY
ASKED.

The assignment is complete.
Here are the answers.

Sirius is a ginger cat whose owner was a Bitcoin developer active on the earliest Bitcoin forums in 2009, posting under the handle "sirius." The cat became the face — and the namesake — of that account, present at the very start of crypto's history.

Because the timeline says so. Long before dog and frog mascots turned into internet culture, Sirius was already sitting on Bitcoin's origin story in 2009 — years ahead of any meme animal that came after.

In a released 2009 email, Satoshi Nakamoto asked "sirius" — the cat's owner — to build a website and write a FAQ, admitting that writing wasn't his strong suit. Sirius agreed and got to work. This website, and the FAQ you're reading right now, complete that assignment.
