Some opinions and things that i've been mulling over...
It is my intention to provoke thought and possibly start a conversation as well as to help me (and possibly others) understand a few things. That is all
* Add thin-clients for the coins so full blockchains don't need to be downloaded (maybe using a consensus algorithm on top of the blockchains)
This isn't that important at an early stage of the software.
* Make the UI easier to use
I watched your video. I'm sure it could be more intuitive but it's a good start.
* Improve the trading algorithm to use a network-wide, ripple style consensus algorithm (to avoid front running and do proper p2p matching, current algorithm is crappy and may have problems)
This is probably the most important part and should get most of the attention.
* Timechains could also be removed but I honestly wouldn't recommend this if you give a damn about security. No timechains = trust and trust is a disaster waiting to happen when it comes to p2p finance and digital asset security.
I agree with you that security is important. But there are also other important features that an exchange must have and it seems to me that a timechain may inhibit one important feature and that is speed. Now maybe I am reading/understanding timechains incorrectly...and I apologize if I am. But when I see a "5 minute interval" I'm understanding that transactions (trades) can take up to 10 minutes ... Am I correct in this thinking? If that is the case then I don't recommend taking this route as the software will be lacking an all too important feature.
In short: IMHO, If this is to work, Coinbend needs to have all the features of a centralized exchange + p2p + security
