  1. While the EVM is Sandboxed, it isn't as powerful as the Bitcoin Network, because it's not Turing Complete.
  2. The EVM can't access hardware layers or anything outside a blockchain node because it's sandboxed.
  3. The EVM is extremely powerful, turing complete and perfect for doing computational intensive things, because of the direct access to the graphics card.

DApps are:

  1. great, because they cut the middle man, run on a trusted platform, apply logic to the blockchain where already economic assets are running and thus allow peer to peer trade.
  2. an amazing way to create new applications. Those applications run entirely separated from other applications on the platform and allow for logical interactions. They can't access any funds to add an additional layer of trust.
  3. a new way of applying logical operations for banks and big financial institutions. This way they can reduce the staff while operating at increased security.

Answer(s): B

q252: dns poisoning is the correct answer, not locator redirection. beaconing is detected from a host. this indicates that the system has been infected with malware, which could be the source of local dns poisoning. location redirection works by either embedding the redirection in the original websites code or having a user click on a url that has an embedded redirect. since users at a different office are not getting redirected, it isnt an embedded redirection on the original website and since the user is manually typing in the url and not clicking a link, it isnt a modified link.
