The picture IS the invoice.
(PgP was the first thing I started devoting time to after I found bitcoin. Steganography was the second)
I'm learning about Steganography: the practice of concealing information within another message. More specifically, I'm learning about Least Significant Bit Steganography, which changes the color of a pixel in a parent image (in this case a meme) by an indistinguishable amount to communicate the information that is hidden.
Like an an invisible watermark.
Within this meme is a secret QR code that holds 10,000 sats worth of e-cash. The money is in the meme.
E-cash, secret messages, signatures, or even private keys (though I wouldn't recommend it) could be hidden in plain sight within an image.
So instead of sending long text strings like "cashuBo2Ftdmh0dHBzOi8..." you can just pay people in memes, which I think is pretty cool.
