Apparently there's some kind of panic about Chia going on in China. It isn't even clear what claims are being made, but here are some points to reiterate (thread)
The network doesn't just trust how much space your local machine claims it has. It's trivial to fool your local farmer into thinking it has lots of space. That doesn't mean it will fool the network.
The new faster plotter isn't a threat to the network's security, it just makes plotting faster and more convenient, which is a good thing. The network is secured by space, not plotting speed
Hpool is using a fundamentally insecure protocol. I've been giving them the benefit of the doubt and assuming that their protocol is only as insecure as is unavoidable, but it could be far worse than that
The rate of blocks being produced in Chia is completely normal and the proofs of space in them check out. The blockchain itself continues to be secure.
The recent chia price drop seems to be a combination of overall drop in crypto markets and an unjustified panic about 'security' from inside China. Whether this panic was caused by someone being intentionally fraudulent or just silliness I don't know.
We aren't going to be helping Hpool improve their protocol. We're completely focused on building an actually secure protocol and once that's out Hpool will be able to use it just like everybody else

People are asking/speculating about the new Chia plotter. It's better but the details are complicated (thread)
What it does is make better use of available cores for multithreading. This results in a big headline speedup on SSD in terms of the minimum number of seconds to finish a whole plot
But it isn't nearly as big an improvement to overall rate of plotting if you compare to running multiple plots on multiple drives at once. It also probably makes almost no difference writing to HD because that was nearly I/O bound already

There's a subtle point about pool/farmer 'difficulty' which I misunderstood the question on in the video this morning so I'll try to explain now (thread)
On the actual running network there's what's called 'work difficulty' which determines a quality threshold above which a proof of space successfully qualifies for making a block
There's a subtlety here about timelords and the rate they're running at which don't matter for this explanation. But know there are timelords and they do important stuff which you rarely have to worry about

And now I present what passes for intellectual commentary about coin issuance (thread) medium.com/@nic__carter/i…
The message is 'Premines are unethical. I have this great idea that you can give yourself a leg up on mining by keeping the PoW algorithm secret beforehand and making your own ASICs in advance'
Because laundering the money at great expense totally changes everything. This being twitter I should clarify that that was sarcasm. It just wastes a bunch of money and makes a burning need to dump to recoup some of that investment

For some odd reason the 'Chia burns out hard drives!' is getting repeated as the fashionable fud. This is odd, because for the most part it's just plain wrong (thread)
If you plot with a plain old HD or an enterprise-class SSD then your drive will survive no problem. Plotting on hard drives, including the one which you'll probably leave your plot on, works fine. It's a bit slower and requires more head room, but works fine.
We've gone to great pains and put a lot of technical wizardry into getting plotting even on HDs to work completely acceptably. The amount of head room it needs isn't much more than one plot, and the time it takes isn't much more than double.

Launch estimate update for chia pooling protocol: Currently the 17th of this month for both plot to pool and a pool prototype being out
This is a bit of a bump out of the plot to pool and a pulling in of the release of a full prototype because the work was more front loaded than I thought at first
How long it will take for there to be high quality pools once our prototype is out I don't know. Plotting to pool protocol will work then and switching is easy though.

There are a few a vaccines out now, so what's the difference between them? Possibly more how they're used than what they are (thread) statnews.com/2021/02/02/com…
Pfizer and Moderna have similar efficacy. One has a second shot after 21 days and the other after 28 days. Can you take the second shot for either in a broad range of time or mix and match for similar efficacy? Probably yes, but we don't know.
Moderna uses 100 micrograms. Pfizer uses 30 micrograms and has fewer side effects. Could you use 30 of Moderna and have it be cheaper with less side effects? Probably yes, but we don't know.
