<h2 class="heading-node">Solana Hacker Hotel DevCon - Raiku: Deterministic Execution Challenge</h2>Total Prize Pool: $2,000 USDC (distributed among top 10 participants - $200 per winner)Eligibility: This bounty is exclusive to attendees of the Solana Hacker Hotel during DevCon 2025 in Buenos Aires, hosted by Superteam Brasil.<hr><h2 class="heading-node">📋 Context</h2>What would you build if execution was guaranteed?Raiku is redefining how Solana executes transactions, shifting the focus from speed to certainty.Through deterministic execution, slot reservations, and transaction-level guarantees, Raiku enables developers to build applications with predictable, reliable, and institutional-grade performance.By making execution deterministic, Raiku is setting a new standard for Solana; One where builders can finally design around when and how their transactions will land.<hr><h2 class="heading-node">🎯 Challenge Statement</h2>What would you build if you had complete control over execution?Raiku's introduction of execution guarantees in the form of Ahead Of Time (AOT) and Just In Time (JIT) slot reservations enable complete control over your user's transaction flow. This means:<ul class="list-node"><li>Batched and cranked transactions can be guaranteed to execute ahead of time</li><li>Retry logic gets offloaded to Raiku's Ackermann Node</li><li>Transactions can be ordered by your application instead of via opaque auction mechanisms</li></ul>We aren't looking for launch-ready applications — instead we want you to imagine what you will be able to build using the developer SDK Raiku will be releasing in the near future. Your submission can be a prototype, simulation, research paper, or design concept.<hr><h2 class="heading-node">🛤️ Suggested Tracks</h2>Choose one of the following directions — or define your own.<h3 class="heading-node">1. Finance Applications</h3>Goal: Prototype DeFi systems or financial mechanisms that are only possible — or significantly improved — with deterministic execution, slot auctions, and pre-confirmations.Examples:<ul class="list-node"><li>Perpetual DEX with zero MEV and deterministic order matching</li><li>Real-time blockspace auction systems</li><li>Cross-chain settlement engines requiring atomic, predictable timing</li><li>Hybrid apps coordinating edge compute workloads (HFT, AI inference, gaming agents)</li><li>AOT-guaranteed fair NFT minting system (batch/Dutch auctions with predictable ordering)</li></ul>Why it matters: These applications push the limits of Solana performance and showcase how Raiku eliminates uncertainty for institutional and high-frequency use cases.<h3 class="heading-node">2. Open-Source Tooling</h3>Goal: Develop open and composable tools that make deterministic execution visible, measurable, and actionable.Examples:<ul class="list-node"><li>Validator dashboards for slot auction analytics and MEV revenue tracking</li><li>Simulation tools for transaction scheduling and slot utilization</li><li>Visualizers for inclusion guarantees and congestion scenarios</li><li>Open documentation, reference implementations, or educational content</li></ul>Why it matters: Tooling bridges the gap between Raiku's infrastructure and developer adoption, creating trust and transparency across the ecosystem.<h3 class="heading-node">3. Economic Research</h3>Goal: Advance the theory and practice of blockspace pricing, slot auctions, and local fee markets.Examples:<ul class="list-node"><li>Simulations of Solana's local fee market under congestion scenarios</li><li>Economic modeling for ahead-of-time (AOT) and just-in-time (JIT) slot auctions</li><li>Studies on validator incentive alignment and MEV mitigation</li><li>Prototypes for blockspace reservation trading or dynamic pricing models</li><li>Local fee market behavior study comparing Solana today vs deterministic execution</li></ul>Why it matters: These research efforts inform the design of Raiku's slot marketplace and contribute to a more sustainable, fair, and efficient Solana.<h3 class="heading-node">4. Visual Simulations &amp; Blueprints</h3>Goal: Make Raiku's primitives tangible through visual demos and integration concepts.Examples:<ul class="list-node"><li>Interactive dashboards showing deterministic slot scheduling</li><li>Visual blueprints for integrating Raiku into DEXs, NFT markets, or games</li><li>Educational explainers for MEV mitigation and blockspace auctions</li><li>Slot Scheduling Visualizer showing real-time and future slot usage</li></ul>Why it matters: Visualization helps both technical and non-technical stakeholders understand and adopt Raiku's deterministic model.<hr><h2 class="heading-node">📤 Deliverables</h2>Submit all of the following:1. Project Submission:<ul class="list-node"><li>Concept document (1–2 pages, Notion, GitHub README, or PDF)</li><li>Optional Demo or prototype (Figma, Framer, Replit, Bubble, etc.)</li><li>Optional: Short Loom Video (max 2 minutes) explaining your concept</li></ul>2.
