Imagine a notebook that thousands of computers share at the same time.
• Every new transfer is written on a new page — this is a block • Each page is locked to the page before it — this is the chain • Everyone can see the notebook, so no one can secretly change an old page
That is why blockchain is trusted for $BTC and $ETH — the record is open, ordered, and very hard to change.
