Hey HN,

In an effort to learn a bit of Solidity, I built a simple proof of concept crypto token backed by physical assets: Brushwagg Coin.

The idea is that users mail in their cards to a centralized repository and are issued a token. Getting the cards back involves calling a few contract functions and mailing in a self addressed envelope.

I started with a single card because supporting every card would require a much larger effort. As a proof of concept I think it's interesting, and the idea of scaling it has a lot of interesting potential uses.

I think physically backed tokens are a really interesting concept, and applying it to assets like trading cards creates a number of interesting applications. For example: using them as loan collateral, renting them out for tournament events, real time price speculation, more accurate price information, as well as the monetization ability of the service, selling cards off of your own exchange at very low prices.

Check it out and let me know your thoughts:
