Summary of "Blockchain for Social Impact: Moving Beyond the Hype"

Core Content

This report explores the potential of blockchain technology to drive social impact across various sectors, analyzing 193 organizations, initiatives, and projects. It provides an overview of the current state of blockchain adoption for social good, key use cases, and the challenges and opportunities that lie ahead.

Main Points

Blockchain's Potential for Social Impact

• Blockchain technology is seen as a transformative tool with the potential to improve efficiency, reduce costs, and promote transparency.
• While the hype around blockchain is significant, the report emphasizes that many initiatives are still in the pilot or idea stage, indicating the technology is in its early phases of application for social good.
• 55% of social-good blockchain initiatives are estimated to have already impacted their beneficiaries by early 2019.

Key Sectors and Use Cases

• Health Sector: Has attracted the most blockchain initiatives, with 25% of all projects focused on this area.
• Payments and Verification: The most common use cases for blockchain initiatives are payments (25%) and records verification (26%).
• Democracy and Governance: Leads in terms of impact readiness, with 62% of projects expected to demonstrate impact within six months.
• Energy, Climate, and Environment: Lags behind in impact readiness, with only 37% expected to show impact within two years.

For-Profit vs. Nonprofit Activity

• 61% of the blockchain initiatives are for-profit, with the highest proportion in Energy (94%), Health (87%), and Financial Inclusion (78%).
• Nonprofit-driven sectors like Philanthropy and Democracy and Governance have fewer for-profit initiatives, with 76% and 33% respectively.

Key Findings

• Early Adoption: Most blockchain initiatives for social impact were launched in 2017 or later, showing a rapid growth trend.
• Proven Impact: 55% of initiatives have already demonstrated impact, and 81% of Democracy and Governance projects are expected to do so by early 2019.
• Innovation and Scalability: The report highlights that while many projects are still in the pilot phase, the technology is enabling new solutions that were previously unattainable.
• Challenges: Adoption is limited due to the need for internet access and digital literacy, especially in emerging markets and rural areas. Most projects are small-scale, with few reaching more than 1,000 beneficiaries.

Blockchain in Action

How Blockchain Works

1. Transaction Request: A user initiates a transaction.
2. Broadcast: The transaction is shared across a peer-to-peer network.
3. Validation: Network computers use algorithms to verify the transaction.
4. Block Creation: Verified transactions are grouped into a block.
5. Blockchain Formation: Blocks are linked in a chain, creating an immutable record.

Benefits of Blockchain

• Transparency: Enables real-time tracking of transactions, useful in areas like aid distribution.
• Immutability: Prevents data tampering, enhancing trust in systems like voter authentication and land registration.
• Reduced Counterparty Risk: Smart contracts automate and secure transactions, reducing reliance on intermediaries.
• Efficient Identity Management: Provides secure, low-cost digital identities for underserved populations.

Case Studies

AgriDigital

• Year Founded: 2015
• Stage: Pilot
• Model: For-Profit
• Application: Supply Chain Management
• Impact: AgriDigital uses blockchain to create a programmable asset (token) representing physical commodities. It enables real-time payments and transparent tracking of goods. Currently, it serves 1,000 farmers and buyers in Australia and plans to expand to the developing world by 2018.

Grassroots Cooperative (with Heifer USA)

• Year Founded: 2017
• Stage: Pilot
• Model: Nonprofit
• Application: Supply Chain Management
• Impact: Launched a blockchain-powered app in 2017 to trace chicken products on the Ethereum blockchain. Consumers can scan barcodes to see the full journey of the product, increasing transparency and trust.

Bext360

• Year Founded: 2015
• Stage: Pilot
• Model: For-Profit
• Application: Supply Chain Management
• Impact: Uses machine learning and AI to analyze and price coffee at the source, ensuring fair and immediate payment to farmers. Tracks coffee through the supply chain using blockchain, aiming to expand to other products and regions by 2018.

Agriculture Context

• Global Challenges: Smallholder farmers, who produce 80% of the world's coffee, often receive less than $2 per day and face payment delays.
• Blockchain Solutions: Aim to improve traceability, transparency, and efficiency in agricultural supply chains. They offer real-time payments and data tracking.
• Regional Focus: Most agricultural blockchain initiatives are based in Europe, Australia, and the US, but 30% are implemented in sub-Saharan Africa.

Challenges in Blockchain Adoption

• Early Stage: Most agricultural blockchain initiatives are less than two years old and have not yet reached large-scale impact.
• Scalability: Limited engagement across the full supply chain, internet access, and digital literacy hinder widespread adoption.
• Connectivity: Initiatives like the Alliance for Affordable Internet are working to improve connectivity in emerging economies.

Conclusion

Blockchain technology holds significant promise for social impact, particularly in sectors like health, agriculture, and democracy. While many projects are still in the pilot phase, the potential for transformation is evident. The report underscores the importance of continued investment, collaboration, and education to overcome current limitations and realize blockchain's full potential in driving positive change.
