Ah, the blockchain - the Holy Grail of crypto, the Alpha and Omega of decentralization, the...wait, what was I talking about again? Oh right, the blockchain.
At its core, a blockchain is just a big, fancy spreadsheet that everybody can see but nobody can change (unless they're a miner with a really powerful computer and a lot of free time).
It's like a giant game of "trust but verify" - you don't have to trust any one person or entity, because you can always check the blockchain to make sure everything's on the up and up.
Example
"I put my trust in the blockchain, because unlike my ex, it would never lie to me or steal my money."
"I tried to explain the blockchain to my grandpa, but he just kept asking me if it was some kind of newfangled Lego set. Bless his heart."
