MemoryCoin Wallet 0.8.581 Bug
« on: January 19, 2014, 12:44:44 PM »

After installing the latest version, I lost wallet encryption and my voting address.
Surprisingly, wallet.dat is not lost. Well done, guys. Good job!

edit: importprivkey [secretkey] is not working either. Deleted all the blockchain files, having a clean install like I do in every new release!

The new version will only show one receiving address - that's your default wallet address.

The other addresses are still present in your wallet and can be added through importprivkey, importmemorywallet etc, but we're encouraging a 'one address = one wallet' model.

If there's a lot of demand, we'll look at adding a switch to allow more addresses to be displayed in the interface.

Yeah, thanks to seraphim, now I figured it out using "listaddressgroupings"
but wallet encryption is a serious bug. Please test it on a Windows x64.

What are you seeing with wallet encryption?

I immediately encrypted again. It was not encrypted when I installed over the older client.

Older client : 0.8.571
New client : 0.8.581 with built-in miner
OS: Win7 x64

seraphim and itsik78 didn't confirm this issue. maybe it is just me but let's keep an eye on that.

Wallet decryption is impossible without your passphrase by design. Could you explain more detailed what you experienced?

If it's true you might have discoverd a serious security issue in either BDB or Bitcoin.

Well, I don't know how to explain it more detailly but I had 0.8.571 installed, then I downloaded 0.8.581 to try built-in miner.
Setup was smooth, but when I opened the client, I saw "Encrypt Wallet" button colored (clickable). Bottom right icon showed the wallet is not encrypted too.
Previously I had some problems with importprivkey in 0.8.571. (error code -4). I have been using MemoryCoin from the earlier versions. (3 versions back) I had to delete the blockchain files when I upgraded to the 0.8.571. Because my address (which is created in the earlier versions) couldn't accept my vote address back then. I even gave my secret-key to emre  to check whether vanitygen tool is working or not. he confirmed it was working on his system. then I created a new secret key with vanitygen. deleted all the files coming back from versions before 0.8.571, did a clean install and importprivkey worked on 0.8.571. Note that there were 2 addresses (my address used for general purposes + my voting address) in my wallet on 0.8.571.

Maybe you should check in the following variables:
Version : 0.8.571 (with 1 normal address + 1 voting address visible on the client)
OS: Windows 7 x64
Then upgrade to 0.8.581 with built-in miner

Checked right now. My wallet was encrypted before upgrade, and still encrypted after the upgrade.

I have after the upgrade lost all addresses except the main one. If the command is entered listaddressgroupings, you can see that they have, but the interface of the program they are not.

v.0.8.581

yep, I thought that was a bug but actually it isn't.

Dubious decision. It would be better if it is configured.

Yes, I think it is fine if someone wants to submit a config patch, but defaults will err on the side of usabilility - the one address, one wallet model is much more intuitive for users, especially new users.

I've found the new address display a bit lacking, too.

I agree the default address UI needed reinforcing, but you could have just dimmed / grayed the font instead of removing.

In the hierarchy of commandline / qt / web UI, I think you need to consider 3 member classes and their "accounting" needs:

- Miners / Customers - a single default address may be preferred.
- Merchants / Service Providers - multiple vanity "receive" addresses and "private network accounting" to identify from address / balances / vote tallies / etc.
- Officers / Developers - May need multiple service provider wallets for multiple projects.

The basic functions are there, so you could implement any additional services as a web UI or qt update, but I like the idea of people spending time in the qt-client instead of web wallets...easier to mine.  (Could we modify Firefox / Chrome with node.js / some plugin to make an MMC web browser that mines with like 1 thread so it's unnoticeable? :) )

Then, instead of just a "wallet", MMC could basically be an "account".  Imagine then if you say "I'll put X MMC satoshi in A MMC address for each Y BTC in B BTC address I own".  You could do all your accounting - through web, or in qt-client - from one wallet.  Is that mastercoin?  Or masterwallet?

You can't stop the signal, Mal. Everything goes somewhere, and I go everywhere.

FreeTrade, I'm sorry buddy, but I don't think you get how Bitcoin addresses are supposed to work. You should NOT think of them as an account. An address is NOT an account. Any time an address sends money it is supposed to be DISPOSED and the change from the transaction is supposed to go to a fresh newly minted address.

Asenski, I'm sorry buddy, but I don't think you get how MemoryCoin addresses are supposed to work. You should think of them as an account. An address is an account. Any time an address sends money it is supposed to send the change from the transaction back to the same address.

Sure, we're trading a little security for usability - but not much. I'm not aware of any examples of the attack you describe.

Blockchain.info uses this very approach with their wallets - so any vulnerability should show up there.

We're not just another clone coin - we're doing things to differentiate the coin - usability is one of them.

Actually - I was wrong about something - the security is not as much of a concern.

Apology accepted - you might want to take a less combative approach when you're not 100% sure of your facts.

The main problem of using the same address over and over is anonymity.

You lose privacy, which is equally bad.

I think we're losing the illusion of privacy. Bitcoin has the same kind of vibe that the internet had in the early days when people thought it was anonymous, but it never really was. I think it's better that users are aware that it's not designed to be private and they need to take extra steps to ensure privacy.

In any case - I'll keep taking a stab at my concept, I think it will be beneficial, and would make using coins pleasant for the average user, while having the added security + privacy.

Thanks - I like the idea and I think it could provide the benefits of easy-to-use with the same security, privacy as Bitcoin too.
