Following up - Here is my pitch.

Proof of Wash:

You moved your coins off exchanges because "trust me" isn't a security model. You run a node so you can verify the chain yourself instead of taking someone's word for it.

Then you go buy detergent with forty ingredients on the label, half of them hidden behind a "fragrance" loophole that legally lets companies not disclose what's in it.

That's the same trust-based system you already decided not to use for your money, except this one's going on your kid's clothes.

Proof of Wash has five ingredients. You can look up every one of them yourself in five minutes.

It's made in small batches by hand, and every batch gets a sequential number on the label. If you've got a question about how or when yours was made, there's an actual answer, not a supply chain you can't see into.

You already hold your own keys. This is the same instinct applied to what's touching your skin.
