I was thinking about situation where for example NSA would want to gain control over significant portion of Ethereum network.
- How much would it cost to for example create mining pool that would be able to perform 51% attack?
- Could they use some existing infrastructure? For example https://en.wikipedia.org/wiki/Titan_(supercomputer) - I picked this one as it was top result for
supercomputer gpuon google..
If you look at Utah data center NSA was OK with spending 1.5 billion dollars on some kind of data center that we don't know that much about.
