The board

Twelve things a graph can do for the first time. Each one carries a bounty, a share of the vault owed to the wallets inside the structure at the moment a trade completes it. A problem is solved once and stays solved.

Nothing here is judged by anyone. The trade that closes a triangle closes it, and the signature of that trade is the proof. Until a problem is solved its row shows only what it asks for.

First triangle

Three wallets, each joined to the other two.

Crossing the threshold

With at least fifty wallets in the graph, the edge count reaches half the wallet count. Past this point a random graph stops being scattered pieces and grows one giant piece.
