Blockchain technology has emerged as a revolutionary decentralized infrastructure and distributed computing paradigm, gaining significant attention from governments, financial institutions, and tech enterprises. This course offers a structured introduction to blockchain fundamentals, applications, and development methodologies.
What Is Blockchain Technology?
Blockchain is a distributed ledger technology that enables secure, transparent, and tamper-proof record-keeping. Its core features include decentralization, immutability, distributed consensus, traceability, and eventual consistency. These characteristics allow trust to be established in inherently untrusted internet environments, eliminating information asymmetry and reducing reliance on centralized third parties.
By leveraging peer-to-peer (P2P) network architecture combined with cryptographic verification and consensus mechanisms, blockchain presents a novel approach to creating trust in digital interactions. This technology forms the foundation for various applications beyond cryptocurrencies, including supply chain management, healthcare records, and digital identity verification.
