What are advantages and disadvantages or using hardware instead of just relying on computers, cellphones or IoT devices like other projects plan to do?
This is indeed a good question. Here's the main advantage:
You can think of our device, Deeper Connect, as a hardware security firewall sitting besides your Wifi router at home (it will eventually replace your Wifi router once we release our next product Deeper Connect - Wifi version). I suppose you never want to turn off your Wifi router at home. Therefore, Deeper Connect should be a 24/7 on device that provides security protects to your home network, allows you open access to any Internet content w/o being censored, and protects your privacy while using the Internet. Besides that, Deeper Connect will run our own blockchain called e^2 chain and earn you Deeper tokens (DPR). If your router will be on 24/7 anyway, why not run a blockchain on it and mine tokens. The power consumption of Deeper Connect can be as low as 5W since e^2 chain uses a different consensus algorithm called PoC (Proof of Credit) that is different from Bitcoin's PoW. You simply don't need to compete hashing power with other nodes.
Computers and cellphones are not reliable 24/7, plus it's not worth it if you compare their power consumption with Deeper Connect. IoT devices normally does not have that computing power to run a blockchain. Deeper Connect has a embedded CPU! In fact, IoT devices at your home (e.g., camera) should join Deeper Network to get security protection and avoid data leakage.
