CONTRACT: Oracle Proxy Contract

[PoulavBhowmick03]

Title: Decentralized Score Feed Aggregation
Description
Create contract to aggregate multiple oracle sources.

Acceptance Criteria:

• Accepts data from 3+ oracle providers
• Uses median value for scores
• Filters outlier data
• Emits NewRound events

Technical Details:

#[starknet::contract]
mod OracleProxy {
    #[storage]
    struct Storage {
        authorized_oracles: LegacyMap<felt252, bool>,
        latest_scores: LegacyMap<felt252, u64>
    }

    #[external(v0)]
    fn submit_score(
        ref self: ContractState,
        player_id: felt252,
        score: u64,
        timestamp: u64
    ) {
        assert(self.authorized_oracles.read(get_caller_address()), 'Unauthorized');
        
        // Store data and calculate median
        let submissions = self.scores.read(player_id);
        submissions.push_back((score, timestamp));
        
        if submissions.len() >= 3 {
            let median = calculate_median(submissions);
            self.latest_scores.write(player_id, median);
        }
    }
}

Notes:

• Implement data freshness checks
• Add oracle reputation system
• Test chainlink + starknet integration
