It took Leslie Lamport eight years to publish one algorithm for these systems because reviewers did not like his parable of a “part-time parliament.” For 10 points each:
[10m] Name these systems that Lamport also analogized to Byzantine generals. These systems usually coordinate concurrent computations via message passing over a network, which makes them less regular than parallel ones.
ANSWER: distributed systems [prompt on networked systems]
[10h] Lamport’s Paxos approximately achieves this key goal of distributed systems, which requires termination, agreement, and a non-trivial output. Raft was designed to be a more understandable way to reach this goal.
ANSWER: distributed consensus
[10e] In 2008, Satoshi Nakamoto used proof of work to ensure consensus on the blockchain tracking this financial asset.
ANSWER: bitcoin [accept BTC; accept XBT; prompt on cryptocurrency; prompt on currency or equivalents]
