Satoshi called them contracts so that's what I call them too. http://en.bitcoin.it/wiki/Contracts The point is to allow for lower trust in certain types of transactions. For instance, consider Kickstarter. They allow people to club together to fund the creation of new things, typically indie movies and games. The problem is you need this trusted middleman to collect peoples pledges and aggregate them. That adds fees, etc. With contracts it can be done entirely with software, all the artist/game programmer would need is to run some software on their website. > What then allows the contract out of the memory pool into a chain? =C2=A0= The > locktime? =C2=A0No, no, forget it...
