The backend market

A game backend is any divi-gamechain node (or compatible one) that someone runs for a game. Operators list themselves on chain:

{ "type": "backend", "op": { "kind": "register", "name": "My node", "url": "https://...",
                             "games": ["tictactoe"], "fee_bps": 0, "contact": "..." } }

backend/register {name, url, games[], fee_bps, contact} and backend/update, keyed by the operator's address. GET /v1/games/backend?view=list lists them.

The site probes each URL's /v1/info and shows uptime, head height and lag, so operators compete on reliability. Fees are shown, not enforced: this is the listing and discovery layer.

A bot or game client can read this list to pick a node, and verify any node's chain by replaying it.
