WALL OF SATOSHI

A PLACE TO TRY THE LIGHTNING NETWORK

This site explains Bitcoin for twelve stops and never once lets you touch it. Here you do. One square costs one sat, a fraction of a cent, so the wall is somewhere to make a real Lightning payment on the real network and watch it land, instead of reading about one. Most people who use Bitcoin have still never opened a channel or scanned an invoice.

THE SURFACE

600 squares across, 350 down. One square is 100 bitcoins, so the whole wall is the 21 million. The sealed block in the corner is the coins nobody has mined yet, about 4%. Mining opens it one square at a time, until the last coin in 2140.

THE RULES

• A square costs one sat more than the last person paid for it.
• A square nobody has painted costs 1 sat. There is no minimum.
• The price never goes down and never resets.
• Nothing is approved and nothing is deleted.
• Eight colours, the same eight the machine uses everywhere else.
• The sealed corner cannot be bought until it is mined.
• No account, no email, no login. You pay an invoice, the squares are yours.

Plus one, never double: doubling would freeze the wall in a fortnight. And you cannot fortify a square by buying it from yourself, because taking your own from 1 sat to 100 costs the whole staircase, 5,050 sats, while somebody taking it from you pays only the next step. A drawing gets expensive only when other people fight for it.

NOBODY MODERATES THIS

No approval queue, no delete button, no editorial judgment. If a drawing bothers you, pay to cover it. Same mechanism as the mempool two stops into the visit: nobody chooses, whoever pays goes through. The one exception is legal, not editorial: content that is illegal to host comes down, because otherwise the whole site does.

WHAT THE LIGHTNING NETWORK IS

Bitcoin writes every payment onto every machine on earth, forever. That is what makes it impossible to undo, and it is far too heavy for small amounts: the record would outlive a one sat payment by a century.

Picture a bar tab. You do not write each round into the world ledger; you keep score with the barman and settle up once at the end. That is the Lightning Network. The difference is that neither of you has to trust the other: every round is signed, and either one can cash it in at any moment.

It was not invented by Satoshi: Joseph Poon and Thaddeus Dryja published it in 2015, four years after he stopped writing. What you meet is an invoice, usually a QR code: one amount, payable once, and it expires. Here they last ten minutes. If you have never paid one, install any Lightning wallet, put a few thousand sats in it, and scan.

HOW TO PAINT

1. You need a Lightning Network wallet with a few sats in it. Any of them works, and setting one up takes a couple of minutes.
2. Fly to the wall. Free exploration takes you there.
3. Pick your squares and a colour.
4. Scan the invoice. Your squares are held for ten minutes while you pay.
5. They are yours the moment the payment lands, and the wall repaints for everybody.

WHERE THE SATS GO

The machine is free and stays free. No advertising, nothing behind a login, no paywall on the visit, in any of the fourteen languages. The wall is what pays for the site to keep running.
