15.4 Blockchain and Its Impact on Business Processes

Blockchain technology revolutionizes how we handle data and transactions. It's a decentralized system that creates an unalterable record, using cryptography and consensus mechanisms to ensure security and trust without middlemen.

Blockchain's impact spans industries, from finance to healthcare. It streamlines processes, enhances transparency, and cuts costs. However, challenges like scalability, energy use, and regulatory hurdles must be addressed for widespread adoption.
