A common language to communicate value

Imagine going to Japan and not knowing a word of Japanese.  Your goal is to buy some salmon sushi.  With some pantomiming and lots of gesturing I think most people would figure out how to convey the value that is desired along with the amount of currency required, however, without a common language it would not be the most efficient transaction in the world.

Promise Language is that common language.  Human readable.  Simple.  Computer readable as well.

Promise Language describes monetary transactions

even in a world of undelivered promises.
