Editing Crossroads (section)

= The big idea – reusability =

There are already hundreds of exchanges and they all do mostly the same thing. Every time these exchanges launch a new UI is created offering users a slight variation on every other trading system. The user is then required to get verified from scratch even though they may have done this on many other exchanges before.

I thought: what if I could design this exchange so that the client would also work for other exchanges that launched? Then the interface would be more useful and it would avoid duplicating work.

I eventually realised that with only minor additions the UI could work not just for asset exchange – but many other types of two-party contracts too.
