Raiku - Inevitable Ideathon track

What would you build if execution was guaranteed?

About Raiku

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.

Challenge Statement

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:

• Batched and cranked transactions can be guaranteed to execute ahead of time

• Retry logic gets offloaded to Raiku’s Ackermann Node

• Transactions can be ordered by your application instead of via opaque auction mechanisms

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.

Suggested Tracks

Choose one of the following directions — or define your own.

1. Finance Applications

Goal: Prototype DeFi systems or financial mechanisms that are only possible — or significantly improved — with deterministic execution, slot auctions, and pre-confirmations.

Examples:

• Perpetual DEX with zero MEV and deterministic order matching

• Real-time blockspace auction systems

• Cross-chain settlement engines requiring atomic, predictable timing

• Hybrid apps coordinating edge compute workloads (HFT, AI inference, gaming agents)

Why it matters: These applications push the limits of Solana performance and showcase how Raiku eliminates uncertainty for institutional and high-frequency use cases.

2. Open-Source Tooling

Goal: Develop open and composable tools that make deterministic execution visible, measurable, and actionable.

Examples:

• Validator dashboards for slot auction analytics and MEV revenue tracking

• Simulation tools for transaction scheduling and slot utilization

• Visualizers for inclusion guarantees and congestion scenarios

• Open documentation, reference implementations, or educational content

Why it matters: Tooling bridges the gap between Raiku’s infrastructure and developer adoption, creating trust and transparency across the ecosystem.

3. Economic Research

Goal: Advance the theory and practice of blockspace pricing, slot auctions, and local fee markets.

Examples:

• Simulations of Solana’s local fee market under congestion scenarios

• Economic modeling for ahead-of-time (AOT) and just-in-time (JIT) slot auctions

• Studies on validator incentive alignment and MEV mitigation

• Prototypes for blockspace reservation trading or dynamic pricing models

Why it matters: These research efforts inform the design of Raiku’s slot marketplace and contribute to a more sustainable, fair, and efficient Solana.

4. Visual Simulations & Blueprints

Goal: Make Raiku’s primitives tangible through visual demos and integration concepts.

Examples:

• Interactive dashboards showing deterministic slot scheduling

• Visual blueprints for integrating Raiku into DEXs, NFT markets, or games

• Educational explainers for MEV mitigation and blockspace auctions

Why it matters: Visualization helps both technical and non-technical stakeholders understand and adopt Raiku’s deterministic model.

Deliverables

Submit one or more of the following:

• Concept document (1–2 pages, Notion, GitHub README, or PDF)

• Demo or prototype (Figma, Framer, Replit, Bubble, etc.)

• Optional: short Loom video (max 2 minutes) explaining your concept

No SDK integration required — focus on clarity, originality, and impact.

Judging Criteria

• Creativity & Originality: Tracks 1 and 3 invite novel applications and research not possible on today’s Solana.

• Relevance to Raiku’s Mission: All tracks directly showcase or extend Raiku’s core primitives and vision.

• Feasibility/Clarity: Tooling and blueprint tracks (2, 4) are accessible for a wide range of participants, while application and research tracks (1, 3) encourage ambitious, high-impact entries.

• Presentation Quality: Visual simulations and integration blueprints provide tangible, compelling submissions.
