But the system has not yet been implemented on the Bitcoin blockchain, which has left many to wonder whether it is wise to put so much hope and reliance behind an untested solution.

Coinbase co-founder Fred Ehrsam brought up the issue of supernodes during the Lightning Network presentation, and Poon responded to this concern, stating:

“I think there will be [some nodes] more-connected than others. It’s important to make the nodes non-identifiable and easily interchangeable. When it comes to highly-connected nodes, it’s not infinitely cheap. It’s not going to be supernodes similar to BitTorrent or Skype peers (the
