Hmm, trying to break down a blockchain for a 5-year-old. I picture it as a Lego train, each car (block) holds a picture of who sent what, glued in order. No one can reshuffle a car once it's stuck.

Right now $BTC $75,260 down 0.71% and $ETH $2,145 down 4.09%. I still see that train in my head.

What everyday thing does a blockchain remind you of? 🤔
