Block Structure
Every block in a blockchain is like a page in a ledger. It contains a list of transactions, a reference to the previous block, a timestamp, and cryptographic fingerprints (hashes) that tie everything together.
Why is this important?
- Blocks are chained together, making it impossible to change history without detection.
- Each block contains a Merkle root, linking all transactions securely.
- Block structure is what makes blockchain technology trustworthy and transparent.
Real-world example: When you look up a block on a block explorer, you see its hash, previous hash, Merkle root, and all included transactions.
