Blockchain technology in simple words is a digital database where information or data is stored in blocks that are linked together to form a chain. This Blockchain Tutorial covers all basic to advanced topics of blockchain like cryptography, Blockchain Algorithms, Blockchain Architecture, Blockchain Security, Smart Contracts, etc.
Blockchain
It is a secure, decentralized digital ledger that records transactions in blocks linked together as a chain. Each block stores verified transaction data, and once added, it cannot be changed or deleted, making the system trustworthy and tamper-proof. It works without third parties like banks or governments, as transactions are verified by a network of computers over the internet. Blockchain is mainly used for secure, transparent transactions, and tools called blockchain explorers help view blocks, transactions, and network details.
