Is bitcoinUnlimited the solution for the current problems bitcoin faces?

[AdolfinWolf]

I have a hard time picking sides/understanding the differences between BitcoinUnlimited ( which is currently pushed by a lot of big miners ) and Segwit.
And also understanding the differences between these two "parties".

I try to follow the discussion on r/Bitcoin, but it is usually downvoting the least popular opinion into oblivion, which makes it almost impossible to see both the negative and positive sides of both parties.


If anyone could give some links in which it is summarized/explained, Thanks.

OK, I will try to present some links about SegWit I found helpful and unbiased:

- Clearing the FUD around Segwit, by achow101 - interesting article where author is debunking some misconceptions and myths about SegWit.
https://achow101.com/2016/04/Segwit-FUD-Clearup

- Philip Daian's blog posts about differences between scaling solutions, i.e. what is better soft or hard fork, also contains interesting view on UASF (recent scaling solution)

Thanks this is indeed very detailed, and gives alot of indepth information about it. Although most of the information is about the authors "Defending" segregrated witness, it still was very educational.

I still have some questions,

If 51% of the miners want smaller blocks they can have them today without BU. They can simply limit the size of their generated blocks -- the max mined block size is a command line option. Also, the max block size to accept is a constant defined in a header file. So 1 simple line of code needs to be changed for miners to ignore blocks bigger than N in all the "Satoshi-derived" clients.

Does this mean that 51% of the miners can call a hardfork for BU, ( I know that is not what they say in the quote, theoritical question)

whereas 95% is needed to activate SegWit?

I know it isn't a X vs X, but these ratios doesn't look right to me.

It is hard to decide what is BS and what actually true. Both sides accuse each other of doing something, having some secret agenda or just bringing Bitcoins end through their actions. But since there are a lot of if and whens involved it is next to impossible to tell what will be the consequences of certain actions.

r/Bitcoin is core focused, so if you want to read another (most of the time) different opinion on reddit then check r/btc out.

That is unfortunately right, AFAIK Bitcoin Unlimited can be activated by 'hostile takeover'.
While Segregated Witness requires super consensus to be accepted, this is impossible to achieve, we can't get 95% consensus on anything.

We can encounter situation where someone manages to force or 'corrupt' 51% of miners and compels them to act against the network (Core).
