Over the last days I spent some time working on a simple Bitcoin network simulator. It is a stochastic event-based continuous-time simulation of Bitcoin miners exchanging messages and building block chains. It simulates latency, bandwidth and also verification speed but it currently does not simulate propagation/inclusion of transactions and instead uses random block sizes.
The simulator includes two examples, one for a 51% attack and the other is an implementation of selfish mining (pretty much 1:1 as described in the paper). With the random parameters I picked it seems like it pays off to mine selfish with >=30% of the hashing power - but take this with a huge grain of salt as this is with a very small network and randomly chosen parameters. And of course it is not a perfect replica of the real world network. Since this is based on my understanding of the Bitcoin network and protocol it would be great if others would take a look and help improve it.
