# Oracle-Based Pricing for Scoring

All scoring on the Rebellion platform is powered by **decentralized or trusted price feeds**, ensuring transparent, tamper-resistant results across all leagues.

***

#### Price Data Sources

Rebellion relies on high-integrity oracles and APIs, including:

* **Chainlink**
* **Binance spot prices**
* Other exchange-grade oracles with strong uptime and verifiability

***

#### Key Safeguards

* **Accurate Open/Close Prices**\
  Asset prices are time-locked at the **start and end** of each contest window.
* **Manipulation Protection**\
  No pricing is sourced from user-submitted data or unverified feeds, minimizing front-running and latency-based exploits.
* **Immutable Scoring**\
  Once a contest ends, scores are **final and cannot be changed**. This prevents disputes and reinforces platform trust.

***

#### Live Leaderboards

To keep users engaged throughout the contest:

* Leaderboards are updated on an **hourly basis**
* Users can track score changes in near real-time
* Notifications may alert players when they climb or drop in rank

***

#### Tiebreaker Rules

In the event of identical scores, ties are resolved using the following hierarchy:

1. **Highest single asset gain**
2. **Most diversified portfolio** (measured by asset class spread and allocation balance)
3. **Randomized tiebreaker** (as a last resort, using on-chain entropy or a transparent selection method)

***

This system ensures that gameplay remains fair, outcomes are provable, and Rebellion stays free from backend interference or score disputes.
