Frequently asked questions

How does blockchain improve supply chains?

Blockchain enhances supply chain transparency and traceability by creating a shared, tamper-resistant record at every handoff point, reducing fraud and building verifiable customer trust.

Are there industries where blockchain isn’t a good fit?

Yes. Blockchain is less efficient for high-speed internal databases or single-party record-keeping, where added complexity outweighs any trust benefit.

What’s the projected growth of blockchain technology?

Adoption is projected to rise from 8% currently implemented to 46%, with analysts estimating a potential $1.76 trillion GDP impact by 2030 if deployment scales as expected.

Does blockchain always lower costs?

Blockchain lowers infrastructure costs by as much as 43% in proven supply chain applications, but overall results depend heavily on implementation quality and how well the technology fits the specific use case.
