Now, with the Bitcoin network we only send each other some amount of Bitcoins in that "registered mail" package. Perhaps that package has a piece of paper with 100 BTC written on it, but it is possible to stuff other things in there. For example, you can put in a stock certificate or a lottery ticket, or maybe some airline miles.Can you elaborate on how Mastercoin will also allow people to create their own virtual currencies on Bitcoin's block chain?Well, the secret sauce is the Master Protocol, which is not so secret since it's open source. Recall the package that had a piece of paper with "100 BTC" written on it, except this time I want to create my own currency. Let's call them "Virgin Space Dollars" (VSD) for a new Star Wars game I am building, and I want to create 1 Billion VSDs.To do that I will need to send a registration transaction to 1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P, which is the Bitcoin address that created the finite set of Mastercoins in existence today. Since all Mastercoin clients watch this Bitcoin address, they will now know that I have registered 1 Billion Virgin Space Dollars. I can start to give them out to people for every light year they travel in my game.In fact, I can give the game out for free to encourage people to use it. As more VSDs are given out I can then provide access to virtual goods merchants who will start accepting VSDs in exchange for virtual goods like virtual teddy bears in my Star Wars game. Let's say these teddy bears get really scarce because they increase the power of the Force, so gamers start buying up VSDs to get their hands on these rare teddy bears. The value of VSDs will increase and I can exchange them for Bitcoins to pay my artist and development teams.

We do not get to choose how the Federal Reserve or the World Bank functions, apart from perhaps a very abstract viewpoint. With Bitcoin and Mastercoin and the many child currencies that will flourish, people can choose which type of social contract related to economic systems they want to be a part of. It's about enabling choice.How would Mastercoin be insulated against price/valuation fluctuations?We have a concept called "Contracts For Difference" that will allow people to choose to essentially take out the volatility of cryptos. This is essentially similar to transferring your currencies into Dollars, Yen or Euros. However, Mastercoins themselves will float freely. A user will be able to opt into pegging some of his Mastercoins into other currencies or commodities.Imagine the Chinese government not being able to censor news because it is embedded in millions of computers world wide, or a Silk Road that has no owner or central server.
