At the bar
The Muntje is the plastic coin from every Dutch festival, now struck by a name on Ethereum. Fast, because we can trust it quickly.
1
The bar has a name too
Coins are handed in to a receiver, and the receiver is an ENS name, just like the organiser who cut them. A bar, a food stand, the cloakroom: whoever takes coins has a name.
2
Scan it, and it's gone
Showing the ID is spending it. The till scans the coin and will not accept it a second time. Nothing goes to the chain per coin; the guest waits for nobody.
3
The night goes on-chain in one batch
Another process picks the moment. Every coin taken that night is handed in at once, cheap. One bad coin refuses the whole batch, so the bar keeps its scans clean.

The count
How many of which coin the bar took is on the chain, under a one-time address only the bar's name can link to itself. The bar can prove the count to the organiser. Nobody else can read it. There is no other reading than this one.
For organisers and pop-up cities
Any event with many vendors, or just a lot of people to organise. De Vrije Munt is the toolkit; what your coin means is yours.
1
Cut a Stempel with your name
The Stempel is the design: everything visible on the coin, its gezichten, decided once when it is cut. Only your ENS name can cut one, and only your name strikes from it. It has an end-date and ink; when either runs out, cut a new one.
2
Strike at the door
The coin exists the moment it is printed. A secret ID is drawn on your own machine and goes on the paper; only its hash goes to the chain. Plastic or plain paper, your choice. The guest pays cash and walks off with a coin.
3
Every editie is its own
Each Stempel has a different face. The coin from your 2010 edition can be made worth more later, or be the thing that opens a certain room next year.
Cutting Stempels and striking coins happens in the Munt's console on the organiser's laptop, not on this site. This site reads.
