In the general case I don't think that majority miner attacks can be defended against without changing the hash algorithm.
Specific cases like "empty blocks" could be addressed via a hard fork.
But there's nothing stopping miners from faking transactions in blocks, sending amounts to themselves, filling the block with OP_RETURNs, or just doing the minimum possible to get around your "fix".
PoW absolutely relies on >50% of miners being honest, always has done.
The purpose of this project is to challenge people to be specific about the details of that hard fork. Currently there are no theoretical proposals, or concrete BIPs to address.
It depends how rationally the market responds, I guess.
A reorg attack and a DoS are equivalent in my mind - anyone who's capable of pulling off a lengthy DoS is also capable of performing a reorg attack, whether they actually do or not is kind of irrelevant.
there is a type of reorg attack I proposed that's now been dubbed a "purge attack", that has the effect of destabalising the network by creating a window for all affected users to double spend their previously "finalised" transactions: https://medium.com/deribitofficial/destabilizing-bitcoin-con...
Potentially - but I think that part of the author's point is that this shouldn't be necessary. Binning an entire keyboard for the sake of a few keys breaking?
We're almost at 100 days since it was last legal for me to interact with another person in my own home - https://esotericnonsense.com for references.
The UK will have vaccinated at least 20 million of the most vulnerable on March 1, providing a high level of protection three weeks later.
From then, the virus becomes simply less relevant than our collective mental health.
Mourning together is better than just being in solitary confinement forever; it's a 100% chance of a mental illness vs. a ~1-5% chance of a physical illness.
March 23, one year since the beginning of restrictions in the UK, I'm done.
Social distancing indefinitely (until Autumn? 2022? 2023? ...) is something other people can do.
I can deal just fine with the current mainland Europe restrictions. I can see my girlfriend, I can meet friends in video chats (and I do, multiple times per week). I definitely would prefer to end this distancing as soon as possible but I currently feel I could technically continue this indefinitely with very few ill effects.
You are not everyone. I know people that are thriving under lockdown. I myself am at least doing better than before. I don't understand how you can think your experience is UNIVERSAL. common, sure. but universal?
If we had paid 1000 GBP per vaccine in the UK, I struggle to see how it would have not been the greatest value for money purchase that will have been made within my entire lifetime.
We're in the middle of a three month period of it being illegal for anyone to visit my home...
If I didn't screw up the math that would be ~7% of UK's 2020 GDP and around 60% of the GDP loss in 2020 compared to 2019. It would be really expensive but the scale of what's happening is also huge.
So maybe not the greatest value for money in a lifetime as there are plenty of much cheaper things with better returns, but at this scale of cost you're probably right.
