What’s happening:

• Major automakers are using blockchain to trace vehicle parts to ensure transparency and environmental sustainability. 
• Blockchain technology is also being explored to create more secure, decentralized payment systems.

How it works:

• Blockchain offers a decentralized, tamper-proof system that records transactions and data across multiple computers. This ensures that once data is entered, it can't be changed or deleted without consensus, making it ideal for industries that rely on secure, verifiable data exchanges.
• Logging every step in the supply chain—from manufacturers to suppliers—helps ensure the authenticity of vehicle parts, tracks EV batteries, and provides insights into recycling and any environmental effects.
• Blockchain streamlines EV charging payments by enabling secure, unified systems across different charging networks.
• Smart contracts can automate key processes, such as warranties and maintenance. 

Going deeper:

• Blockchain is being used to create digital battery passports, which track an EV battery’s life cycle. This is relevant in Europe, where regulations require these passports for environmental sustainability.
• This technology makes carbon credit trading more transparent, motivating manufacturers and consumers to minimize carbon emissions. 
• Possibility of peer-to-peer energy trading where EV owners can trade surplus energy directly with others to enhance decentralized markets and encourage energy conservation.

Challenges of adopting blockchain in automotive:

• Many automotive companies have invested heavily in their existing IT infrastructure, making blockchain integration complex and costly.
• As the volume of data in the automotive industry grows, blockchain networks face challenges in scaling to handle the increased data flow.
• Regulatory uncertainty is an issue since legal and regulatory frameworks governing blockchain in the automotive sector are still being developed, particularly concerning data privacy, security, and cross-border transactions.
• Adoption barriers include a need for more awareness, high implementation costs, and the need for technical expertise. These barriers slow down consumer and industry-wide acceptance of blockchain technology.

Big companies are making moves:

• BMW (OTC: BMWYY) and Bosch are part of the MOBI (mobility open blockchain initiative) consortium, working on projects like decentralized vehicle identity systems and smart contracts for vehicle transactions.
• Circularise, a Dutch company, has developed a blockchain platform to track the lifecycle of automotive parts to ensure that materials used in manufacturing are sourced sustainably and parts are properly recycled.
