What's the significance of seeing an IP listed as banned for a large negative number of seconds (as a response to the "bans" command in bitmonerod)?

QC is coming, gradually at first, then quite suddenly.  It really is time to panic, before the suddenly phase.

The situation gets more dire every day:  http://phys.org/news/2016-03-physicists-quantum-fredkin-gate.html

Do you have suggestions for how the developers should respond to this threat now (aside from panicking)?

Formulate and articulate a plan to manage transition to qc-aware signature algorithms. Add necessary supporting interfaces to development plans. 

Eventually someone will submit a pull request.  If they know what sort of thing will be well-received, i.e. what and where are the prefered interfaces, it becomes about 100x more likely that pull request will be useful.

Shen Noether commented this on reddit:

Once the current round of improvements is finished (apps/ guis/multisig/etc) the attention will likely move to quantum secure, and hopefully by then there will be more signature implementations available to choose from, I.e. Hopefully a Bernstein type will have coded the new ref for quantum. Note that a lot of the necessary math ( I.e. Ring sigs / one time keys) has been studied already in the literature..

Three people you probably already know, talking about why privacy matters:

It would be interesting to know what their opinion of privacy focussed crypto's might be.

I predict a QC threat will come right after the ubiquitous flying car.

Getting ahead of the issue can only be good for XMR.  Failing to do so can only be bad.

Wait then fork as per schedule?

In August, 2015, NSA announced that it is planning to transition "in the not too distant future" to a new cipher suite that is resistant to quantum attacks. "Unfortunately, the growth of elliptic curve use has bumped up against the fact of continued progress in the research on quantum computing, necessitating a re-evaluation of our cryptographic strategy." NSA advised: "For those partners and vendors that have not yet made the transition to Suite B algorithms, we recommend not making a significant expenditure to do so at this point but instead to prepare for the upcoming quantum resistant algorithm transition.

[birr]

Someone will have to vet the NSA algorithms.
I believe one of the existing  public-key algos has a critical weakness that was deliberately introduced.  Is that correct?

So since the fork have there been any orphan blocks from the different pools now that the network is pulling 2 minute blocks vs the old 1 minute per.  I haven't looked except on the pool I mine on.  There have been none so far where I am.  Anybody followed this?

[dovaboy]

are the miners and mining pools current on the front page? i dont wanna buy anymore, would rather pay for electricity and watch XMR show up..

I am sure there have been some. Bitcoin with 10mn still has several a day...

EDIT: several a day probably overstated, though fairly frequent even with 10mn.

Hi,

I am a little late with this, but I need a little bit of help with 2 problems.
I switched to 0.9.1.0 Hydrogen Helix.

1.
One sweet surprise was that finally I can use view-only wallets too. (Thank you and well done!)

However, something is not as good as I'd wish:
In the case the wallet was used to also send out coins, the displayed balance is incorrect: it shows the amount of received coins without subtracting the sent out coins.
Am I doing something wrong, is there something I can do to see correct value, or it's a known bug?

2.
I have some dust, mostly from early mining. I've seen that it can be "consolidated". How can I know how much that consolidation costs (to see if it worth it)?


Thanks

[1] The viewkey only shows incoming transactions, therefore the "balance" is incorrect when there are also outgoing transactions. There is a way to show outgoing transactions too, but it is a bit more convoluted than we initially thought. Convuluted as in it isn't done by a simple "key". See discussion here:

https://www.reddit.com/r/Monero/comments/4ce5ui/what_is_the_use_of_view_only_wallet_when_its/

[2] You can use the sweep_dust command to do that.

[NeuroticFish]

Thank you for the answers.
For 1. I understood now and I will also do the reading on reddit
About 2. I am still uncertain ... is sweep_dust for free? Or how can its cost be calculated?

I read your post incorrectly. I think you can't really calculate its costs precisely in advance. However, if you use the command simplewallet will give you the cost before sending if I recall correctly.

Nothing wrong with getting ahead of the (not fully formed) issue, unless it takes limited resources away from (more clearly defined) projects with better infrastructural return in the short run.
