💡Pro Tip
Remembering the Structure
Think of blockchain as a chain of blocks where each block is a page in a ledger. Each page (block) contains transactions and a reference to the previous page (hash), making it tamper-evident.
⚡Gold Rule
Centralization vs. Decentralization
Blockchain eliminates the need for a central authority by distributing the ledger across a network of computers (nodes).
📖Word Origin
From 'block' (a group of transactions) + 'chain' (linked sequence), coined in 2008 by Satoshi Nakamoto in the Bitcoin whitepaper.
📝Usage Notes
Blockchain is often confused with Bitcoin, but Bitcoin is just one application of blockchain technology. Blockchain can be public (permissionless) or private (permissioned).
