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

So why bimonerod thinks the highest block of the blockchain is that 1009962?

That means you are connected to a peer that thinks the height is 1009962, hence the minus 2 days ahead.

It will soon be followed by a message stating that that peer was blocked in relaxing light blue letters.

Well ok. But how an from where the bitmonerod anyway gets the real highest one block, the block 1013521? While bitmonerod at the same moment thinks the highest one block is 1009962.

Your node evaluated its current chain as the longest valid chain (the one with 1013521 as the top block).
Then it got info from that other block a different top block (1009962).

Your node will now have to check that chain in order to determine if it is valid according to the rules (protocol) it has.
And it also checks which chain has more work on it.

It is this evaluation of every block by every node in the network that sets an agreement (consensus) about which top block (meaning which chain) is the valid one.

Probably just a naughty peer. That is, a peer that is still on an old version and thus got booted off the network after the hardfork. Use "diff" and/or "status" on bitmonerod to check which block height you are on, it should be equal to the blockheight on moneroblocks.info. It gets the right/current blockheight from peers that are on the right version.

bitmonerod doesn't, but in order to find the chain with the highest cumulative proof-of-work, that is also verified, it needs to actually download the alternative chain and verify it.

I did not get to point completely.

Has bitmonerod, or does it think it has a wrong blockchain? And is bitmonerod going to download a whole blockchain again, such a blockchain it thinks is a real one? Or has it to be done manually?

As far as I know 0.9.3 should auto refresh. As far as asking a bunch of specific questions about your wallet the best bet is to jump onto freenode IRC #monero and ask on there.

This board is available to search and documents the answers, so why ask to go to #monero? 

0.9.3 doesn't refresh, so why is that?  This could be a problem where your coins are stolen and since it doesn't refresh, you may think they are still there, right? Is there a bug or is there a problem with my wallet?

Regarding refresh, autorefresh should work in 9.3. However, in case it doesn't work what is wrong with just typing refresh?

In trying to find out about what happened in my sweep_dust, I did a rescan and everything in my wallet appears good.  I have made a note to run the refresh every time I open my wallet now, an auto refresh would be nice, not a big deal.  I don't open the 'ol wallet too much I'm going to hold and pray it hits out of the solar system, I have a feeling secure money is smart money.

For old wallets, I think auto-refresh isn't set. Type "set auto-refresh 1" into the simplewallet console.

MiniNero phone wallet for Android

This is currently in alpha state, and is about 60-70 % functional on the test server. Not suitable for actual use yet.

Screenshots: http://imgur.com/a/xODgl

This should eventually be feature equivalent to the existing windows version:

If there are any android/java developers we could use some more resources.

Is there a web wallet for this alt coin?

Yes, MyMonero, it is run by one of the core-team members, namely Fluffypony. However, always use webwallets with the usual caution. That is, it's not advised to store larg(er) amounts on it.

Protect them from being stolen. If the pubkey is revealed quantum computing is able to steal his coins. If you move them to a new address it won't reveal the pubkey of that address, unless you reuse it.
OK, I went and read about it. So, they can't break new 'unused' address, but still they will know that money were moved and now lay at that address. Am I right?

Yes that's right. Also the protection only exists while the address are sitting unspent on the blockchain. When you try to spend you have to reveal the public key so QC could still be used to break it during the interval until it is confirmed. That greatly narrows the time window (from years to minutes) and would require a faster QC to be effective.

The comments about moving to Monero (maybe in jest?) are off-base. Monero would also be broken by QC and we don't have the protection of publishing hashes of public keys either.


Of course we were jocking.  I read an article by Vitalik Buterin concerning QC and there were mentioned Lamport Signatures as a solution.


Alternatively winterwitz signatures, both are really inefficient at the moment though.

And thank you for explanation! I wonder how do you guys have so much time and patience answering all this and that here and on reddit and elsewhere. That's amazing.
