When asked, “What exactly is blockchain?”
I usually answer like this: Bitcoin’s first block was mined on January 3, 2009, and embedded in it was a headline from that day’s Times. If you change a block in the past, its hash changes, and the “previous hash” recorded in every subsequent block will no longer match.
$BTC 76918.02 (-2.16%)
If anything wasn’t clear, leave a comment and ask.
