Abstract

Blockchain technology is a decentralized and distributed ledger system that ensures secure, transparent, and tamper-resistant data transactions. It uses cryptographic hashing, consensus algorithms, and smart contracts to eliminate the need for intermediaries. Blockchain is widely applied in finance, supply chain management, digital identity, healthcare data security, and decentralized applications (DApps).
