Blockchain

What is Blockchain?

Blockchain is a distributed ledger technology that enables secure, transparent, and tamper-proof record-keeping. It consists of blocks of data that are cryptographically linked together, forming a chain. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

Why Learn Blockchain?

Learning Blockchain is crucial for several reasons:

• High demand for blockchain developers in various industries
• Enables you to work on decentralized applications (DApps)
• Opportunities to innovate in finance, supply chain, healthcare, and more
• Builds a strong foundation in cryptography and distributed systems
