There are countless real-world problems (outside of finance) that blockchain could theoretically solve. However, despite over 15 years of blockchain development, most attempts have failed to gain adoption due to technological limitations, poor business models, or lack of real demand.

With Solana’s high-speed, low-cost architecture, we want to re-examine these problems and explore whether blockchain is now a viable solution.

Your task is to write a detailed research piece identifying at least 10 real-world problems that Solana could help solve.

For each problem, you must:

1. Explain the problem and why it matters.

2. Describe how Solana could be used to solve it.

3. Analyze past attempts (if any) to solve this problem using blockchain. Were they successful? Why or why not?

4. Evaluate feasibility today—both from a technical and business perspective.

⚠️ Examples of Problems to Explore

Blood Bank Data on Solana 🩸

• Problem: National blood shortages happen due to poor tracking of available blood units (storage slots, blood type, expiration).

• Potential Solution: A public Solana-based registry for real-time tracking of blood availability across hospitals.

• Has it been tried before? Were past solutions successful or not?

Decentralized Location Data Registry 📍

• Problem: Many e-commerce sites in Vietnam rely on outdated, unofficial GitHub repos for location data (provinces → districts → streets).

• Potential Solution: A public, blockchain-based registry that keeps an immutable record of geographical data updates.

On-Chain Financial Records for Global Lending 💵

• Problem: Businesses in emerging markets struggle to get loans from foreign banks due to trust issues with local financial reports.

• Potential Solution: Using Solana to store financial record hashes for verifiable, tamper-proof financial statements.

• Past Attempts: Have there been any blockchain-based credit scoring systems?

Your submission must go beyond these examples—we encourage you to think creatively and explore problems across various industries:

• Healthcare

• Supply Chain

• Finance & Credit

• Public Data & Governance

• Intellectual Property

• Gaming & Digital Identity

Judging Criteria

Submissions will be evaluated based on:

✅ Depth of research – Do you thoroughly analyze the problem and possible solutions?

✅ Realism & feasibility – Are your proposed blockchain solutions actually implementable?

✅ Insightfulness – Do you provide unique insights into why past solutions failed and what makes now different?

✅ Clarity – Is your writing clear, structured, and easy to understand?
