How many miners and/or pools are there? Can the distribution of miners be determined? Would mining pools be incentivised to merge? Is miner collusion through 51% attacks a present threat? Could they double-spend their coins? How are they impacted by replace-by-fee (RBF)?
These questions are from the MOOC sessions 7.2, 8.2, and 9.2 covering the Byzantine Generals’ Problem, which took place on February 26th 2017, September 15th 2017, and February 23rd 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.

Why miner that has 51% hashpower mines 1.4 blocks a day?
2% ahead
If every node validates every transaction why do we need miners?
So what type of vulnerabilities does BCH present with zero confirmation transactions?
You are the Bitcoin Jesus!
thanks Andreas for all your work..
With the addition of bitcoin on CBOE selfish miners have a new vector by shorting btc
What i like about Andreas is that is very humble even though that his knowledge on subject is pretty much top notch.
I was wondering if you have seen this white paper that claims that bitcoin mining becomes unstable when block rewards becomes incentively insignificant and transaction fees begin to make up the majority of the coinbase transaction:
https://via.hypothes.is/http://randomwalker.info/publications/mining_CCS.pdf
I've been looking at some game theoretical scenarios, but I was thinking that in the case of bitcoin block reward going to near zero (which won't happen for some time), that if the coinbase tx has a long enough lock time, then if someone was to try to fork blocks that by the time their undercutting attack rewrote the history, that what they collect would be worth next to nothing.
Do you have any thoughts on this? This paper was written by CS PhD candidates at Princeton and has some computer simulator results…
I BTCP is a fork of BTC, why does it have more coins in circulation than BTC does?
This is a criminally under-viewed channel.
I know one of them is Omnia miners.
Are mining pools not a form of centralization? It is my understand that Bitmain and it’s affiliates, friends, partners, connections etc. control over 50% of the mining…
we are the aliens that will take over this century
question??? why is bitcoin cash hardforking again for the second time on May 15th? i do not understand… will i get 1 bitcoin cash for every bitcoin i own?….
I just bought all your books!
I have a question! Will Bitcoin die because people losing their private key?how can we prevent this.
Are you coming to Seattle anytime soon? Keep up the Great work AA!
