Blockchain Technology

Blockchain technology is a distributed ledger system that enables secure, transparent, and tamper-proof data management. It has evolved to encompass a wide range of applications beyond digital currency, including supply chain management, voting systems, and healthcare record management. With its decentralized architecture and cryptographic hashing, blockchain technology provides a secure and reliable way to conduct transactions and store data. For example, Walmart has implemented a blockchain-based system to track its food supply chain, while Estonia has used blockchain to secure its healthcare records.
