BTC ecology is more important than transaction time.You can refer to XCP.
Tough I have been using Bitcoin for years I don't know what BTC ecology is ... but I believe if you want to perform an Internet of Things function then the transaction time is pretty vital. I thought, if you want to turn on a sensor or turn on/off a light you can't wait 60 seconds until the transaction is processed (i.e.. included) in the blockchain.
This is a wonderful project like BitBay or GadgetCoin and I am sure you have a working solution, I would just like to understand how your solution works terms of one of the most important aspects of it, the real time hardware control.
XTC is directly based on BTC blockchain. The transaction time is BTC block interval.
