Blockchain is a decentralized digital ledger technology designed to record data in a secure, transparent, and tamper-proof manner. It stores transactions in blocks, and each block is cryptographically linked to the previous one, making it nearly impossible to alter past records. Instead of relying on a central authority, blockchain networks use distributed nodes that validate transactions through consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS).

The core purpose of blockchain is to create trustless systems where data integrity, immutability, security, and transparency are guaranteed. Beyond cryptocurrencies, blockchain has become a foundational technology for multiple industries including supply chain, finance, identity management, healthcare, voting systems, and smart contracts. It offers a revolutionary framework for building decentralized, efficient, and highly secure digital ecosystems.
