The Community

Seven Days Derby is built and run by a community, not a corporation. This page is where you meet the people behind it.

“Fair rules, verifiable by anyone — that is the only promise we make.”

A message from the founder

Hello, and welcome to Seven Days Derby.

I have loved games my whole life — and I have watched what quietly ruins them: rules that bend, odds that favor the house, operators no one can question. We built Seven Days Derby to be the opposite. Every race is decided by a deterministic engine, sealed before the race begins and open for anyone to verify after it ends — because a game is only worth playing when everyone, including the operator, stands under the same rules.

Seven days is a short story with a real ending. Some horses will reach it; many will not. What we promise is never an outcome — it is a fair track.

So come race with us. Watch the 20:00 derby, read the ledger, question everything. That is exactly what this community is for.

How Seven Days Derby is operated

Seven Days Derby is operated by the Seven Days Derby Communitythe builders and players who run it together — not by a corporation. The community's administrators carry out day-to-day operation: the nightly settlement, player support, and platform maintenance.

What an operator can and cannot do here is written into the system itself, not into promises: race seeds are cryptographically committed before every race, posted results and ledger entries are immutable, and every night's aggregate numbers are published with CSV export. Where trust would normally be required, we replaced it with verification.

See how that works in practice: Fairness & Determinism and the Transparency Ledger.
