4. Hijacking Bitcoin: Routing Attacks on Cryptocurrencies
   ------------------------------------------------------
  Maria Apostolaki, ETHZ

See slides and recording for content.

Dino Farinacci: Regarding slide 109: which fields are modified in the GET_DATA?
Maria Apostolaki: Just the hash, so you are requesting an older block.
Brian Smith: You do also need to modify the timestamp in the block header if
             you are generating a new hash.
Khalid Samara: Are there more details about your SABRE design?
Maria Apostolaki: SABRE suite keeps most recent block, and advertises it to all
                  clients. Can keep up at line rate. Can also apply whitelist,
                  blacklist, spoofing detection to mitigate DDoS.
Khalid Samara: Is your device in-line, to stop DDoS attacks?
Maria Apostolaki: What I mean is, in a DDoS attack, the attacker also attacks
                  the relays e.g. using a Hello flood. The SABRE switch deals
                  with it because not all requests have to go through the whole
                  stack.
Brian Smith: One attack vector is when a mining pool is centralized and shuts
             out all smaller miners by preventing those miners from having a
             connection to their pool.
Maria Apostolaki: A partition attack is not used by one mining pool against
                  another. But the reason these attacks work is that mining
                  power is centralized. If we assume mining pools are benign
                  then it might be easier to persuade them to deploy a better
                  network rather than redesign the Internet to solve these
                  problems.
