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).
