# Playoffs

> Lock in your entire playoff bracket before game one. ESPN-style scoring. Sybil-resistant.

## The game

A single-elimination tournament is announced (4-128 teams). You fill out your entire bracket — every round, every matchup, all the way to the final — and commit it before the first game starts. Then you reveal your picks round by round as games settle.

## How it works

<Steps>
  <Step title="Bracket published">
    The operator sets up the tournament with teams, seeds, and round-by-round point multipliers.
  </Step>

  <Step title="Commit your full bracket">
    Pick every game across every round. Your entire bracket is sealed as a single Merkle root on-chain. You cannot change it after entry.
  </Step>

  <Step title="Games play out">
    Real-world games are resolved on the oracle. The contract records outcomes round by round.
  </Step>

  <Step title="Reveal per round">
    After each round settles, a reveal window opens. You prove your picks for that round against your original Merkle commitment.
  </Step>

  <Step title="Scoring and payout">
    ESPN-style path-dependent scoring: a later-round pick only counts if you also got the feeder game right. Top 3 finishers split the pool.
  </Step>
</Steps>

## Why full commitment matters

The biggest problem with on-chain brackets is Sybil attacks — one person spins up 50 wallets with different brackets and guarantees a top finish. Full upfront commitment kills this:

* **50 wallets = 50 entry fees.** Expensive to Sybil.
* **Full bracket locked before game one.** No adjusting after seeing round 1 results.
* **Path-dependent scoring.** Random brackets score badly because later picks depend on earlier ones being correct.

## Key details
