…with this quiz.
Originally presented to the bitcoin-dev mailing list. (Only ZmnSCPxj answered, and he did not do particularly well.)
Here it is:
- We could change DC to make miner-theft impossible, by making it a layer1 consensus rule that miners never steal. Why is this cure worse than the disease?
- If 100% hashrate wanted to steal coins from a DC sidechain *as quickly as possible*, how long would this take (in blocks)?
- Per sidechain per year (ie, per 52560 blocks), how many DC withdrawals can take place (maximum)? How many can be attempted?
- (Ie, how does the 'train track metaphor' work, from ~1h5m in the "Overview and Misconceptions" video)?
- Which two?
- How is everyone else, expected to move their coins from chain to chain?
- (Obviously, this improves UX.) But why does it also improve security?
- What do the parameters b and m stand for (in the DC security model)?
- How can m possibly be above 1? Give an example of a sidechain-attribute which may cause this situation to arise.
- For which range of m, is DC designed to deter sc-theft?
- If DC could be changed to magically deter theft across all ranges of m, why would that be bad for sidechain users in general?
- If imminent victims of a DC-based theft, used a mainchain UASF to prohibit the future theft-withdrawal, then how would this affect non-DC users?
- In what ways might the BTC network one day become uncompetitive? And how is this different from caring about a sidechain's m and b?
- If DC were successful, Altcoin-investors would be harmed. Two Maximalist-groups would also be slightly harmed -- who are these?
Should I provide the answers?? Well, most of the answers are somewhere on drivechain.info – try the Peer Review section or the FAQ or the original spec.comments powered by Disqus
