Blockchain technology, initially popularized through Bitcoin, has evolved far beyond cryptocurrency. Recognized at the Davos Forum as one of seven core technologies driving the Fourth Industrial Revolution, blockchain is projected to manage 10% of global GDP by 2025. Here's how this decentralized technology is transforming diverse sectors.
How Blockchain Works: A Trust-Based System
At its core, blockchain is a distributed ledger technology:
- Eliminates centralized control through peer-to-peer networks
- Ensures data integrity via cryptographic chaining of blocks
- Enables trustless transactions through consensus mechanisms
