FAQ's

What is the transformative potential of blockchain technology?

The most important role of blockchain in supply chains is to ensure information transparency and traceability (Jasrotia et al., 2024). It has significant advantages in green supply chains, including information authenticity assurance, carbon footprint reduction, and product sustainability verification.

What is the power of blockchain technology?

Blockchains can be used to make data in any industry immutable—meaning it cannot be altered. Since a block can't be changed, the only trust needed is at the point where a user or program enters data.

How blockchain technology will change the world?

Blockchain technology is poised to dramatically transform commerce across every industry, including financial and legal services, agriculture, healthcare, and more. Currently, the most prevalent example of blockchain technology is the Bitcoin blockchain.

Why is blockchain so powerful?

Decentralized network: Blockchain spreads its data across many computers, so hackers can't gain anything from attacking one single place. The network also eliminates the need for a middleman. This decentralization makes transactions more transparent and trustworthy.

What is the main advantage of blockchain technology?

By creating a record that can't be altered and is encrypted end-to-end, the blockchain helps prevent fraud and unauthorized activity. You can address privacy issues on the blockchain by anonymizing personal data and by using permissions to prevent access.
