What is Blockchain?

Blockchain is a distributed ledger technology that allows data to be stored across a network of computers in a way that is secure, transparent, and tamper-proof. Each block in a blockchain contains a list of transactions, and once a block is added to the chain, it cannot be altered without altering all subsequent blocks, which requires consensus from the network.

Importance of Understanding Blockchain

Understanding blockchain is crucial for leveraging its potential in various sectors such as finance, supply chain management, healthcare, and more. It enables individuals and businesses to create decentralized applications (DApps), execute smart contracts, and develop new business models.

Understanding this technology can be daunting due to its complex nature.
