A block is the fundamental building unit of a blockchain. Think of it as a digital container that stores a batch of verified transactions.
🎯 Core Concept
Just like a shipping container holds multiple packages, a blockchain block bundles multiple transactions together. Once sealed (mined), the block becomes permanent and unchangeable.

- ✓Order: Blocks establish a chronological timeline of all transactions
