How could government "take over" bitshares?
Do all DPOS delegates currently operate anonymously over TOR, only identifying themselves with a random pseudonym? Is TOR actually useful and not prone to timing attacks? Can DPOS be scaled while using TOR? Are all DPOS delegates supposedly distributed worldwide, but all located on the same Amazon server? What percent of DPOS delegates are actually unique individuals?
That's how?
Admittedly, PoW is in the same boat, if not far worse off, but until questions like this can be addressed, DPOS isn't exactly bulletproof.
I have personally run a delegate through tor, and sent transactions. Support is not currently built into the client so I had to build the client in whonix to get multiple connections open at the same time. I am not a tor expert, but to the best of my knowledge DPOS could scale through tor just fine. Some delegates are running their nodes on their personal networks, and some have rented server space. Its impossible to be sure how many actual individuals there are in the top 101 delegates, but I just looked through, and it appears theres around 40-50 different individuals. I personally would like to see 101 different individuals spread out all over the world keeping only the fees needed to pay for their hardware/electricity/bandwidth and returning the rest to all shareholders. Others have different ideas. Some would like to see delegates keeping more of the fees and reinvesting those fees in the ecosystem. Some picture delegates being professional teams, with different stated goals and perhaps running multiple delegates per team. The beautiful part is that it is up to the actual users of the token to decide.
As far as DPOS being co-opted by the government, I don't think thats a likely possibility. The gov thugs would never give up their ability to inflate at will to fund the welfare/warfare state. If their spending and inflation was on a blockchain and had an immediate impact on the purchasing power of other tokens, they would not be able to spend a tenth of what they currently do.
