What is Blockchain ?
Blockchain Blockchain is a decentralized, secure, and transparent digital ledger that records transactions across multiple computers or nodes, eliminating the need for intermediaries. It enables trust, accountability, and automation through cryptographic techniques and consensus mechanisms, revolutionizing industries beyond cryptocurrencies.
