Summary of Blockchain for Social Impact

Core Content

This report explores the potential of blockchain technology to drive social impact, analyzing 193 blockchain-based initiatives across various sectors. It provides an overview of the current state of blockchain applications in social impact, identifies key trends, and highlights case studies that demonstrate real-world implementation and outcomes.

Main Points

• Blockchain for Social Impact is Still in Early Stages: Most initiatives are relatively new, with 34% started in 2017 or later. Only 55% are estimated to have demonstrated impact by early 2019.
• Democracy and Governance Leads in Impact Potential: 62% of projects in this sector are expected to show impact within the next six months, making it the most advanced area for social impact.
• Energy Initiatives Lag in Impact: 63% of Energy projects are not expected to demonstrate impact within two years, indicating that this sector is still in early development.
• Health Sector Has the Most Blockchain Initiatives: 25% of all blockchain initiatives are focused on health, nearly double the next leading sector, Financial Inclusion (13%).
• Blockchain Offers Unique Benefits: It enables immutable records, transparent tracking, and secure verification of transactions. These features are critical for sectors like health, agriculture, and land rights.
• For-Profit Activity is More Common in Certain Sectors: 61% of initiatives are for-profit. Energy (94%), Health (87%), and Financial Inclusion (78%) have the highest proportion of for-profit organizations.
• Blockchain Facilitates Payments and Identity Verification: The most common use cases are payments (25%) and record verification (26%). Smart contracts reduce counterparty risk and increase efficiency.
• Blockchain is a Tool for Trust and Transparency: It addresses three core elements of trust — identity, ownership, and verification — through cryptographic methods and decentralized systems.

Key Sectors and Case Studies

Agriculture

• Overview: Blockchain in agriculture is in early stages, with most initiatives based in Europe, Australia, and the U.S. However, 30% of implementations are in sub-Saharan Africa.
• Impact Potential: 13% of initiatives could reach over one million beneficiaries. 75% of those beyond the concept stage are for-profit.
• Challenges: Most projects are in concept or pilot stages, with limited scalability. Adoption requires internet access and digital literacy.
• Case Study: AgriDigital
  • Year Founded: 2015
  • Stage: Pilot
  • Model: For-Profit
  • Application: Supply Chain Management
  • Description: AgriDigital uses blockchain to create a programmable asset (token) representing physical commodities. This enables real-time payments and transparent tracking of goods. The company is currently used by 1,000 farmers and buyers in Australia and plans to expand to the developing world by 2018.
• Case Study: Grassroots Cooperative (with Heifer USA)
  • Year Founded: 2017
  • Stage: Pilot
  • Model: Nonprofit
  • Application: Supply Chain Management
  • Description: Grassroots uses blockchain to trace chicken products on the Ethereum blockchain, allowing consumers to scan barcodes and see the full journey of the product. The project is small but growing, with around 15 farmers and 1,000 consumers accessing the system monthly.
• Case Study: Bext360
  • Year Founded: 2015
  • Stage: Pilot
  • Model: For-Profit
  • Application: Supply Chain Management
  • Description: Bext360 combines machine learning and blockchain to create a transparent coffee supply chain. It enables immediate and fair payment to farmers and tracks the product through various stages using blockchain. It operates in Ethiopia, Nicaragua, Colombia, Uganda, and California, with plans to expand to other products like cocoa and nuts.

Democracy and Governance

• Overview: This sector has the most blockchain initiatives, with 21 projects identified. The Estonian government is a notable early adopter, offering 99% of its services as e-services.
• Key Highlights: 38% of initiatives are for-profit, compared to 61% in other sectors. This indicates a growing interest in both public and private applications of blockchain in governance.

Blockchain Primer

• Origin: Blockchain was introduced with Bitcoin in 2008 and became operational in 2009.
• Function: It is a decentralized, secure, and transparent ledger system that records transactions in blocks linked together in a chain.
• Cryptography: Blockchain uses cryptographic hashing and digital signatures to ensure data integrity and secure identity verification.
• Smart Contracts: These are self-executing contracts with the terms of the agreement directly written into code, enabling automatic and secure transactions.
• Tokenization: Blockchain allows for the creation of tokens that can represent digital assets or commodities, facilitating new forms of value exchange.

Conclusion

Blockchain has the potential to revolutionize various sectors by increasing transparency, reducing fraud, and improving efficiency. While the technology is still in its early stages for most social impact applications, there are already successful pilots in areas like agriculture and governance. The report emphasizes the need for continued innovation, collaboration, and data sharing to realize blockchain's full potential for social good.
