Blocks are formed by bundling verified transactions into a new unit and establishing a cryptographic proof. The block is then connected to the previous one, creating a chain that governs immutability. Validation, consensus rules, and propagation determine eligibility and finality,…

Blockchain provides a tamper-evident ledger distributed across a network. Transactions are recorded in blocks, secured by cryptographic hashes and synchronized via consensus. Smart contracts embed programmable rules that automate enforcement without central authority. Together, these elements enable verifiable transparency, decentralized…
