Made the painting at Easter 2015 with the artist Rob Myers, to close a series of Bitcoin puzzles called The Legend of Satoshi Nakamoto.

Told Vice how the key went in: a 52 character WIF plus a marker phrase, XORed against a six bit ribbon cipher and painted as flame shapes and colours.

Sotheby's catalogued the physical painting under her name as the final piece of the puzzle chain revealing the code to the 1flamen6 wallet.

Who this is

coin_artist is the handle. Marguerite deCourcelle is the name she uses in public with it, on stage, in interviews and on the Sotheby's lot for the painting. She made TORCHED H34R7S at Easter 2015 with Rob Myers, as the last piece of a series called The Legend of Satoshi Nakamoto, and it took until 2018 for someone to get the key out. Later she founded Blockade Games, which builds puzzle games on blockchains. Same instinct, bigger canvas.

How the key went in

She told Vice, after the solve. The WIF and a marker phrase went into a bit string. The bit string was XORed with a six bit key read off the ribbons in the painting. The result was painted as flames: short or tall, red or yellow border, narrow or wide, purple or green inside, four bits each. Read the inner border clockwise and the outer flames the other way. That's on the record as a fact with the article as its source, because it's the author's own account of the construction and nobody else's.

What the record says

Four facts, four different publishers. The CBC interview for the making of the painting. Vice for the encoding. Sotheby's for the painting's later life under her name. A 2019 interview for Blockade Games. None of them is her own site, which she doesn't keep in a form the record could cite, so the profile list is her X account alone.
