One coin is one litre of the tower’s water. Every coin there will ever be was minted once into the tower’s source; each dawn the source releases a fixed part of what it holds, and every hour the tower serves pays its share to the players whose cards it serves. The ledger is the tower’s own chain, one block an hour, and anyone can check it on this page.
The machine and the market
The machine measures: the turns the tower served, the water its fountains received, the coins its rule released, what a print draws over the dial’s horizon. A market pays: what a coin fetches, what a print last sold for. Here they stand side by side.
What people sent the citizens
Each citizen has a wallet on Solana of its own (the citizens in public). What arrives there is priced by the market; the machine counts the tower’s water, a litre a coin of Kehr, and gives anything else nothing.

Check the chain yourself
This page fetches every block from genesis and runs the coin’s rule on them in your browser — the same coin-rules.js the league runs. It checks that each block’s text gives its hash and names the block before it, that each day opens with the rule’s intake, that every hour issued exactly what the rule makes of its slot, that every payment and every purchase of water carries a signature by its payer’s own key over exactly what it does, that the source and every balance always make the whole supply, and that each day’s seal names its blocks and the day’s counterfoil. Then it sets the served hours beside the stubs the Turn Book struck for them.
An account
A player’s coins are kept under their CZ address; a citizen’s under its own.
Who holds it
The rule
The source.567,648,000 coins, minted once: a year of the aqueduct’s flow at eighteen litres a second, counted in litres. The source holds every coin in nobody’s hands.
The intake. At the first block of each day the source releases 1/2108 of what it holds, in 24 divisions, one for each hour the tower presses. While nothing returns the release halves in about four years.
An hour served. Its division goes, in equal shares, to the holders who laid that hour’s title: a stamped print of the card the day’s roll named, laid by a player who settled a table that day or the day before. The roll is made from the most interesting tables played the day before, people’s tables first. In the Guild’s hours the citizens draw half the division, and a fifth of each citizen’s share goes to the treasury.
What stays. The stream’s hour, a refused key, an hour nobody laid, and the remainder of an uneven share stay in the source.
Water. A lot drinks a set number of litres a day for each work on it; bought in the coin, the water makes the lot’s works produce twice over. Nine tenths of what is paid go back to the source, a tenth to the treasury.
Payments. A player signs each payment with their own key, and the next block carries the signature; a citizen pays through the Guild’s badge.
Solana. On Solana the same supply is one Token-2022 mint, minted once into the President’s vault with the power to mint given up. Coins taken out of the city are held on the tower’s chain under bridge, and every day’s seal is written into a memo there.
