What is Blockchain & How Does It Work?

Blockchain is a decentralized, immutable ledger that records transactions transparently and securely. Each block contains transaction data, cryptographically linked to the previous block, preventing tampering. This technology underpins cryptocurrencies, smart contracts, and decentralized applications, offering unparalleled security and efficiency.

The Difference Between Public & Private Blockchains

Public blockchains like Bitcoin and Ethereum are open, decentralized networks, while private blockchains are permissioned and controlled by select participants. Businesses often favor private blockchains for efficiency and regulatory compliance, while public chains provide transparency and security.

Smart Contracts: Automating Transactions Securely

Smart contracts execute predefined conditions without intermediaries, reducing costs and delays. They are widely used in DeFi, NFT marketplaces, and supply chain management. By automating processes, smart contracts enhance security, efficiency, and trust.
