Linera-Specific Implementation Examples

Personal Chain Architecture

// Each player gets their own sovereign microchain
#[derive(RootView)]
#[view(context = ViewStorageContext)]
pub struct PlayerChain {
    // Portfolio management with zero-cost reads
    pub portfolio_history: LogView<PortfolioEntry>,

    // Real-time performance tracking
    pub performance_metrics: MapView<Timestamp, PerformanceSnapshot>,

    // AI learning and personalization
    pub ai_preferences: RegisterView<PlayerAIProfile>,

    // Social connections and reputation
    pub social_connections: MapView<AccountOwner, SocialConnection>,

    // Achievement collection with dynamic progression
    pub achievements: MapView<BadgeType, DynamicAchievement>,
}

Native Oracle Integration

// Professional-grade AI with native HTTP access
impl AIAnalysisContract {
    async fn generate_market_analysis(&mut self, crypto: &str) -> Result<MarketAnalysis, AIError> {
        // Direct HTTP queries to external APIs (impossible on traditional chains)
        let price_data = self.runtime.http_query(&format!(
            "https://api.coingecko.com/api/v3/simple/price?ids={}&vs_currencies=usd&include_24hr_change=true",
            crypto
        )).await?;

        let news_sentiment = self.runtime.http_query(&format!(
            "https://newsapi.org/v2/everything?q={}&language=en&sortBy=publishedAt",
            crypto
        )).await?;

        let social_sentiment = self.runtime.http_query(&format!(
            "https://api.twitter.com/2/tweets/search/recent?query={}&tweet.fields=public_metrics",
            crypto
        )).await?;

        // Run sophisticated ML models with real-time data
        self.run_comprehensive_analysis(price_data, news_sentiment, social_sentiment).await
    }
}

Cross-Chain Event Streams

// Global social features through event streams
impl SocialEventSystem {
    async fn broadcast_achievement(&self, event: AchievementEvent) -> Result<(), EventError> {
        // Instant global broadcasting (impossible on single-chain systems)
        self.runtime.publish_event(SocialEvent::AchievementUnlocked {
            player: event.player,
            achievement: event.achievement,
            rarity: event.rarity,
            celebration_tier: self.calculate_celebration_tier(&event),
        }).await?;

        // Automatically trigger cross-application updates
        self.update_cross_chain_reputation(event.player, &event.achievement).await?;

        Ok(())
    }
}

Unlimited Parallel Game Instances

// Unlimited concurrent leagues without performance impact
impl LeagueOrchestrator {
    async fn create_new_league(&mut self, config: LeagueConfig) -> Result<ChainId, OrchestratorError> {
        // Create dedicated microchain for this league
        let league_chain = self.runtime.create_chain(
            ChainType::TemporaryLeague,
            config.clone()
        ).await?;

        // Perfect isolation - no impact on other leagues
        league_chain.initialize_league_state(config).await?;

        // Auto-cleanup after competition ends
        league_chain.schedule_expiry(config.end_time).await?;

        Ok(league_chain.id())
    }
}
