Difficulty must have soared as i mined 864 within 14 minutes and now haven't mined anything at all for more than half an hour.

Unless you have your own pushpoold and blkmond set up, the churn will clobber you.

For a while I had been thinking that you were running a mining pool too.  But when you say "miner fees", you mean transaction fees that flexcoin pays out when sending to non-flexcoin accounts.

That isn't his wallet.  That is his wallet + block chain + global IP address list + bitcoin logs + database logs.

The wallet on my server is 176128 bytes.

Slightly off topic, but what the fuck is Phinnaeus's problem?  I'm imagining him as an 11 year old kid with impulse control problems that can't resist the urge to spam every thread that might possibly mention wallets.

iv got the new version running 1.1-23

what does each field mean?

key=bitcoin private key?
message=duh
signature=?
public=bitcoin public key?
version=do i need to change that, or is that there for future reasons

key = bitcoin private key, can be found by dumping the wallet.
message = message to sign or verify
signature = signature of message to verify
publickey = public key of message to verify
Version = used to create the address format.  Should be 0 currently, but can be different in the future, or for testnet.

To get key info, you only need to fill in the Key: field.
To sign a message, you need to fill in Key: and Message:.
To verify a signature, you need to fill in Message:, Signature: and Publickey:.
2887  Bitcoin / Development & Technical Discussion / Re: Password-protected private key export format on: August 10, 2011, 07:44:59 PM
The difference between an 8 byte salt and a 4 byte salt isn't 4 bytes, and it isn't a factor of 2.  It is a factor of over 4 billion.  It is the difference between "Got a minute?" and "Sometime after the end of the universe".

In reality, it is probably not that big of a deal.  Precomputing AES tables isn't a trivial task, and even 4 or 5 bits of salt is probably enough to make it impractical for well beyond the potential lifetime of one of these protected keys.

But cryptosystems are designed with defense in depth for very good reasons.  When a weakness in one part is discovered, it is usually not a catastrophe because we have added redundant security measures.

So, the question is:  Is saving a few keystrokes, maybe several times per year for maybe a couple billion users, worth the slight risk that an AES break won't be "phew, gotta upgrade", but instead be "All your addresses are belong to us"?  I would vote for the extra keystrokes, but that might just be me.

By the way, this is a nifty idea.  One thought that came to mind was embedding metadata into the key itself using DER.  Since these keys are not usable on the network, they should maybe not be assigned a key version prefix.

That one works.  The "Thank you guys!" one does not.
2889  Bitcoin / Development & Technical Discussion / Re: Pywallet: manage your wallet on: August 10, 2011, 07:01:12 PM
Still nothing.

I tried it with a different key.  By the way, if you use --web, it ignores --wallet= on the command line.  It'd be nice if that carried over.

I went used Dump Your Wallet and copied out one of the "sec" values, scroll down to the info/sign/verify section, paste in the key, Get Info.  Results:

Code:
Address (Bitcoin): 17LeVE2fjEK7ncqxCToU4McytDHLUhKpyx
Privkey (Bitcoin): [secret]
Hexprivkey: [secret]

Type "maybe different words?" into the message box, Get Info.  Result:

Go back up, clear out the Key: field.  Paste the sig and public key into the correct boxes, Get Info.  Result:

Code:
Signature of 'maybe different words?' by 17LeVE2fjEK7ncqxCToU4McytDHLUhKpyx is NOT 304402206e1704baf1c1238077b420b74c07dcdf6964155614005fe20089ce83445e2895022009ebcd27124a52ecdc90a4398438c5c400cc9dcd259560ec90d752a876946178

I changed the message to "test" just to make sure the question mark wasn messing up the URL encoding, and it still failed verification.

I installed it anyway.  For those you you doing it the hard way, you can find the ecdsa package on this page, or use this direct link.

Not having much luck signing.  I tried to verify my own message, and it fails.  I clicked a few more times, and I get a different signature each time.

3. The exact measurements of the distributed computing network must be given in

The speed of the bitcoin network, measured in FLOPS, is exactly zero.

What new features?

By the way, this doesn't work with Python 2.4.2.  I jumped right up to 2.7, so I don't know what the minimum version was.  Among other things, the "A if Condition else B" syntax appears to be pretty new.

Interesting. Would be fascinating if you could trace the 'lineage' of the first bitcoins from the genesis block to someone holding them today. Well, I shouldn't say 'if' - that is what the blockchain is for. I don't think I'll be tackling that task, however.

The collectible aspect is a cool idea.

The genesis coins haven't been spent yet.

My C++ is really rusty, and I'm reading the diff out of context, but I believe that this patch just lets you add URLs to two lists, one that gets POSTs for every new block that comes in, and one that gets POSTs for every transaction that comes in related to the running wallet.
2899  Bitcoin / Development & Technical Discussion / Re: [PULL] monitortx monitorblocks listmonitored getblock on: August 10, 2011, 01:35:52 AM
From reading your other posts, I get the impression that you want to know about addresses that are not in the wallet.  I don't think this patch gives you that.

Let me try this again.

For people that don't donate at least 2.5%, there is no difference (in the long run).  For people that do donate at least that much, and for the pool itself, there is a difference.  A huge difference.

As to your idea that he doesn't know what it means, that is obviously incorrect, which is very easy to demonstrate:  The biggest part of the incentive structure of this free pool is built around that difference.
That sentence "For ... run)." is ... again ... wrong. As my example showed.

So now I have an actual answer also - it is used as an incentive for people to pay a donation.
Yep that's a clear reason.

I'm not sure that you understand what I mean by "in the long run".  To be clear, it means "averaged over many rounds".

Yes, in any one round following an invalid block, some people will be up and some people will be down.  However, averaged over many rounds they should all be pretty much even.
