Yes...and, more; e.g:
Sybil attack to change ledger entries - No risk, completely destructive
Description: A Sybil attack is a person creating a lot of nodes on the network, possibly thousands on a single machine, in order to get a disproportionate vote on networks where each node gets an equal vote.
https://bitcointalk.org/index.php?topic=1219264.msg12775946#msg12775946The Sybil attack is not conflated with the definition of a "full" node in all designs. In my design there is no global voting, thus Sybil attacking by making many fake "full" nodes wouldn't be effective (but it would be in terms of the network partitioning feature). But also in my design a fake "full" node would be useless as well for other reasons. Any way, we should not continue this sort of discussion, because designs can't be analyzed piecemeal like this. Please wait for me to reach the point where I want to release a white paper or more complete description of my design, then we can discuss the details.
