The global demand for cobalt, a scarce metal essential for heat conduction in lithium-ion batteries, continues to surge. These batteries power everything from smartphones to electric vehicles, with a typical EV battery requiring 18 to 20 pounds of cobalt.
However, the journey of minerals like cobalt through the supply chain is notoriously complex and inefficient. Many operational and commercial practices within the mining and metals sector remain outdated and costly. Paper-based processes result in millions of dollars in annual losses, while a lack of data transparency opens the door to fraud, unsafe working conditions, and regulatory challenges.
To tackle these issues, innovative blockchain-powered initiatives are being developed to bring greater efficiency, security, and traceability to mineral supply chains.
The Role of Blockchain in Mineral Traceability
Blockchain technology offers a decentralized and immutable ledger system, making it ideal for tracking materials throughout their journey—from extraction to end-use. This is especially relevant for high-demand minerals like cobalt, where provenance and ethical sourcing are growing concerns.
Most of the world’s cobalt originates from the Democratic Republic of the Congo. However, the metal typically passes through numerous companies and countries before reaching manufacturers, making traceability nearly impossible with traditional methods.
Through blockchain, each transaction and movement can be recorded in a secure, transparent, and tamper-proof manner. This allows companies and consumers to verify the origin and handling of minerals, supporting more responsible and sustainable sourcing practices.
Real-World Blockchain Initiatives in Mining
Several industry collaborations are already demonstrating the potential of blockchain in mining:
- A consortium involving major players like Ford Motor Company and LG Chem is using a blockchain network to enhance transparency in mineral traceability and provenance.
- Another project, in partnership with MineHub Technologies, focuses on reducing reliance on paper documentation and manual processes. The platform uses blockchain to digitize transactions, track shipments, and automate contracts, leading to faster processing, reduced costs, and fewer intermediaries.
One of the first implementations of the MineHub platform is tracking ore from GoldCorp’s Peñasquito Mine in Mexico throughout its route to market. This end-to-end visibility helps minimize fraud, improve compliance, and accelerate trade.
Advantages of Blockchain in Mining Operations
Increased Transparency and Trust
By providing an unalterable record of transactions, blockchain enables all parties—including miners, smelters, manufacturers, and regulators—to access the same verified information. This reduces disputes and increases accountability.
Reduction in Manual Processes
Many mining supply chains still rely on phone calls, paper contracts, and manual verification. Blockchain introduces smart contracts that automate agreements, accelerate sales, and reduce the need for intermediaries.
Enhanced Regulatory Compliance
International regulations, such as the OECD Due Diligence Guidance, require companies to prove that their minerals are sourced responsibly. Blockchain makes it easier to demonstrate compliance by providing auditable and real-time data.
Ethical Sourcing and Sustainability
Blockchain helps ensure that minerals are mined under safe and fair working conditions. This is particularly important in regions where artisanal and small-scale mining is common and often informal.
Overcoming Industry Challenges
The mining industry faces unique hurdles in digitization, including the involvement of numerous small-scale miners who may lack access to advanced technology. Successful blockchain solutions must be inclusive and accessible, supporting data entry via mobile devices and simple interfaces.
Moreover, integrating large industrial miners with smaller operations requires a platform that is both scalable and user-friendly. Lessons learned from other blockchain applications—such as those in food safety and global shipping—are helping inform these efforts.

Frequently Asked Questions
What is blockchain’s primary benefit in the mining industry?
Blockchain enhances transparency, reduces fraud, and automates manual processes. It helps track minerals from the source to the end consumer, ensuring ethical and efficient supply chain management.
How does blockchain improve traceability?
Each step in the supply chain is recorded on a decentralized ledger that cannot be altered. This creates a permanent and verifiable record of the mineral’s journey, including origin, handling, and transactions.
Can small-scale miners participate in blockchain systems?
Yes. Modern blockchain platforms are designed to be accessible via mobile devices and simple applications, allowing artisanal miners to input data without needing advanced technical skills.
What are smart contracts in mining?
Smart contracts are self-executing agreements with terms directly written into code. In mining, they can automate payments, verify compliance, and trigger actions once conditions are met—reducing delays and manual oversight.
Is blockchain only used for cobalt?
While early pilots often focus on high-demand minerals like cobalt, the technology is applicable to a wide range of metals and minerals, particularly those requiring proof of ethical sourcing.
How does blockchain support sustainability?
By providing proof of responsible sourcing and working conditions, blockchain helps consumers and companies make informed decisions that align with environmental and social governance goals.
Conclusion
Blockchain technology holds significant promise for modernizing the mining industry. Through improved traceability, automation, and data integrity, it addresses long-standing inefficiencies and ethical concerns. As adoption grows, blockchain could become a standard tool for creating more transparent, sustainable, and secure mineral supply chains worldwide.
