How ready is Corda for production deployment in a real commercial environment?
Performance - Proven ability to handle tens/hundreds of thousands of transactions per day.
Stability - Bug free operation over extended period of time.
Upgrades - Versions can be upgraded cleanly without need for major re-engineering of client apps.
Are there any examples yet of organizations using Corda productively for large scale applications. If not, is there a target date for a version to be available that will really be production-ready?
