Blockchain is best known for its role in powering the next evolution of finance, but its core properties—secure, tamper-proof recordkeeping, real-time data transparency, and programmable automation—make it equally valuable for modernizing a range of government operations.

Across the U.S. federal government and other national governments, agencies are increasingly exploring how blockchain technology can enhance transparency, strengthen oversight, and improve the delivery of public services. By addressing operational challenges with digital-first infrastructure, blockchain offers practical solutions across a wide range of use cases in the public sector.

The following examples highlight agency-specific use cases where blockchain can deliver significant improvements in security, performance, and accountability.

1. Agriculture, Rural Development, FDA, and Related Agencies

Agency focus: Food and Drug Administration

Secure Recordkeeping for Food Safety and Recalls

Food safety incidents often involve multiple producers, transporters, and retailers—making it difficult to trace contamination quickly. Blockchain technology can be used to log inspection dates, temperature records, and other key data at critical points in the food supply chain. This creates a permanent record that can help identify the source of contamination, limit recall scope, and speed up response times.

2. Commerce, Justice, Science, and Related Agencies 

Agency focus: U.S. Patent and Trademark Office

Verifiable Record of IP Transfers and Licensing Agreements

Patent and trademark ownership transfers, along with licensing agreements, can be recorded on a blockchain to create a time-stamped, verifiable history of changes in rights and control. This helps clarify who holds legal rights at any point in time, especially when ownership passes through multiple entities. It can reduce disputes, streamline enforcement, and complement existing United States Patent and Trademark Office (USPTO) records without replacing current systems.

3. Defense

Agency focus: Office of the Secretary of Defense

Secure Identity and Credential Verification for Deployed Personnel

Military personnel operate across multiple commands, bases, and international theaters where quick verification of identity, role, and clearances is essential. A blockchain-based credentialing system can store time-stamped, tamper-resistant records for certifications, duty assignments, medical clearances, and access levels. Authorized units and partners can instantly verify credentials without relying on disconnected databases or manual paperwork, reducing delays in deployment, access, and mission coordination while maintaining operational security.

Reliable Equipment Maintenance Records Across Units

Military equipment often moves between units, bases, and commands. Blockchain technology can be used to create a shared maintenance record that tracks inspections, repairs, and replacements across the lifecycle of vehicles, aircraft, and weapons systems. Each update is time-stamped and accessible to authorized personnel, ensuring equipment is mission-ready by eliminating delays caused by missing or inconsistent records during transfers or deployments.

Improved Military Logistics and Supply Chain Operations

Blockchain technology can improve how the military tracks and manages assets across global operations. A recent Department of Defense pilot successfully demonstrated the benefits in a live environment, using blockchain to facilitate the movement and tracking of 600 tons of equipment more efficiently than traditional systems—a “quantity exceeding the combined total moved in the previous 31 months”. The results highlight significant potential for cost savings, faster coordination, and more resilient supply chains across the Department of Defense.

4. Energy and Water Development

Agency focus: Department of Energy

Transparent Renewable Energy Certificate Tracking Across Jurisdictions

Renewable energy certificates (RECs) are used to track and trade clean electricity, but the current system is fragmented. Different states and utilities use separate platforms, which makes it harder to coordinate and leads to double-counting. A blockchain-based registry can record when RECs are created, transferred, and retired, all in one place and in real time.

5. Financial Services and General Government 

Agency focus: Financial Crimes Enforcement Network (FinCEN) 

Automated Compliance Logging and Reporting for Financial Institutions

Banks and other regulated institutions can use blockchain to log compliance actions required under AML/CFT regulations, such as when reports are filed, accounts are flagged, or restrictions are applied. Blockchain technology enables these records to be time-stamped and auditable, helping institutions maintain regulatory compliance. Smart contracts can also be programmed to trigger alerts or internal reviews when thresholds are crossed, like repeated high-risk transfers or structuring activity. This enables institutions to respond faster, reduce manual workload, and stay aligned with FinCEN’s expectations for monitoring and enforcement.

6. Interior, Environment, and Related Agencies

Agency focus: Bureau of Land Management 

Auditable Source-To-Sale Supply Chain Tracking and Resource Rights

Blockchain technologies can strengthen federal oversight of natural resource extraction, such as timber, seafood, rare earth elements, and critical minerals, by providing transparent, end-to-end tracking from source to point of sale. This real-time traceability supports enforcement of environmental, labor, and sustainability regulations, helping prevent illegal logging, overfishing, and unlicensed mining. Immutable blockchain records create a tamper-proof history of resource origin, ownership transfers, and compliance certifications, enabling regulators to verify lawful practices and consumers to make informed choices. 

7. Labor, Health and Human Services, Education, and Related Agencies

Agency focus: Department of Health and Human Services (HHS)

Tamper-Proof Universal Health Records

While universal health records that consolidate patient data across providers offer significant benefits, such as improved care coordination, reduced medical errors, and faster diagnosis, centralized systems have proven vulnerable to cyberattacks. Blockchain technology offers a secure alternative, allowing patients to maintain ownership of their medical records and keep them private while enabling authorized providers to access accurate, up-to-date information when needed.

8. Legislative Branch

Agency focus: House of Representatives

Secure and Verifiable Voting Systems

Voting systems built on blockchain technology could significantly strengthen the integrity of election and legislative processes. By creating an immutable, transparent ledger of every vote cast (while maintaining the privacy of who cast which ballot), blockchains can ensure that records cannot be altered or deleted, enabling real-time auditing and end-to-end verifiability. This enhances public trust in electoral outcomes and helps safeguard democratic institutions from interference or fraud. When combined with digital voter IDs, blockchain systems also make it easier and more secure for eligible citizens to participate in elections from anywhere, particularly those facing in-person voting challenges, such as the disabled or military personnel stationed overseas.

9. Military Construction, Veterans Affairs, and Related Agencies

Agency focus: Department of Defense—Civil

Auditable Military Construction Projects

Blockchain technology can enhance accountability and transparency across the entire lifecycle of military construction projects. From the initial bidding process to contract awards, project execution, and final delivery, blockchain ensures that every action is time-stamped, traceable, and verifiable. Smart contracts can automate milestone-based payouts, releasing funds only when independent oversight bodies confirm that specific construction benchmarks have been met. This reduces the risk of cost overruns, corruption, and delays while creating a permanent audit trail that improves oversight, compliance, and contractor performance.

10. State, Foreign Operations, and Related Programs

Agency focus: Department of State

Transparent Compliance Tracking for Treaties and Global Agreements

Critical information around global treaties and agreements, such as financial spending and deforestation rates, can be recorded on a blockchain ledger and made accessible to all signatory nations and independent observers. This would enable real-time monitoring of compliance with agreements, reduce information asymmetries between nations, and eliminate opportunities for selective reporting or data manipulation. Smart contracts could automate enforcement by applying preset financial incentives or penalties based on verified performance against agreed-upon benchmarks. A transparent historical record also makes it easier to hold nations accountable and build long-term trust in multilateral agreements.

11. Transportation, Housing and Urban Development, and Related Agencies

Agency focus: Department of Transportation

Verifiable Tracking of Goods From Their Point of Origin 

Blockchain can be used to verify the tracking of goods as they enter national and international supply chains, creating a time-stamped record of origin. This record can follow each shipment through ports, rail, trucking, and air transport, helping transportation authorities, inspectors, and carriers verify where shipments came from and whether they’ve been altered in transit. This improves traceability, streamlines customs checks, and supports faster, more informed decision-making across the transportation network.

Modernizing the Public Sector With Blockchain

Blockchain is a foundational technology that can help federal agencies operate with greater speed, trust, and accountability. From food safety and renewable energy tracking to secure identity verification, blockchain can streamline and modernize the public sector.
