Facilitating faster market development
XStack’s matching engine, Prodigy, is a multi market matching engine with a market plugin design.
There are 2 parts to Prodigy:
Prodigy can have multiple plugins installed and can run multiple markets concurrently.
By implementing market rules and behaviour in a plugin, it makes supporting new markets or adding functionality to existing markets a lot easier. Supporting a new market only requires developing a plugin - not implementing a completely new matching engine. Adding new capabilities to a market only requires testing its plugin. In both cases, Prodigy’s core is not modified.
In addition, plugins allow hosting of different versions of the same plugin. This can facilitate upgrading and allow other systems to incremental move from one version to the next. Upgrades can be smoother and risks reduced.
For an exchange business, the advantage of plugins boils down to accelerated market development.
