Interesting paper. While I wonder how easy it is find suiteable routes for DoSing LN in practice I guess we'll see soon enough now that this paper has been released.

It's also always nice to see a paper that ends with proposed solutions that do not include an attempt to push a new pre-mined alt coin. Also mitigation seems to be mostly tweaking some parameters with existing LN implementations and safeguards that seem relatively straight-forward to implement -- eg. loop avoidance, as mentioned in the paper -- so we're not utterly doomed yet. It goes to show that we're still in early stages though.
