Blockchain is a distributed digital ledger technology that records transactions across a network of computers in a secure, transparent, and immutable way. Instead of relying on a central authority, blockchain uses cryptographic techniques and consensus mechanisms to ensure data integrity and trust among participants.
Blockchain is best known for supporting cryptocurrencies, but its applications extend far beyond digital currency. It is used in areas such as supply chain management, digital identity, smart contracts, and secure data sharing, enabling greater transparency and efficiency.
Beyond technology, blockchain has the potential to transform how organizations and individuals exchange value and information. By reducing reliance on intermediaries, it introduces new models of trust, decentralization, and accountability in digital systems.
