Lots of projects claim to be decentralized. It is important to disclose exactly where this project is and what the remaining limitations are.

Towards that end, we will note some points about this project and answer what can be done about them and what the limiting factors are.

The objective is to have this project completely decentralized, where no one entity could take down the network.

Limitations

Seed Nodes

Currently all the seed nodes used for the DHT are run by Fireduck. We should add some diversity. If all the seed nodes were unreachable or down new nodes would be unable to join the DHT and wouldn't be able to find peers for channels.


Fixes:

IP Address Discovery

Currently, nodes reach out to an app in Google App Engine in order to discover their own IPv4 and IPv6 public addresses. See: https://github.com/snowblossomcoin/channels/blob/master/src/NetworkExaminer.java

If this broke, nodes would be unable to announce themselves as peers on the network.

Fixes:

snowchannel.io hosting

The proxy implementatation points x.snowblossom.io to a channel where x is the channel identifier. To help with that. *.snowblossom.io is a publicly reachable site that tells people to fix their proxy settings. It is hosted on CloudFront/S3.

If this went away, people would get timeouts or other errors when their proxy settings were not set correct. Not a huge deal.

Source Control

Source control is all on github. Anyone could have a clone, but it is still a single point that would have a big impact on the system if disrupted.
