Hi guys,
I've just installed Windows 64 0.5.0 wallet over 0lder 0.3.7 and I'm getting error upon start:
"wallet.dat corrupt, salvage failed". Please help.

I hope, you have backup copy of the wallet.dat. Or even current wallet.dat still work with 0.3.7.
we 1st time see this. Really, we had a problem during migration 32->64, but problem was related to blockchain index, not to wallet.dat.

OK. Most easiest way - to create a new wallet, and just move balance from the old wallet to a new one.

Also, I would like to note: 0.5.0 has other index structure, than 0.3.7, so blockchain will be reindexed at 1st start.

What did we do this week:

http://www.blockchainengine.org/33-week/

Release Candidate Wallet ready! Our programmers have worked very, and there is reason to wonder. We went directly from the bitcoin 0.6 kernel to the bitcoin 0.10.2. It was damn hard work, but we did it. We are the first POS cryptocurrency that did it))



https://sourceforge.net/projects/emercoin/files/0.5.0/

Congratulations on the release of the New Release Candidate 0.5.0rc1!

Links for Win32/64 have been added to http://emercoin.com/#download

Thanks for the answer. Yes, I have a copy of old wallet, but this is really frustrating that new version 0.5.0 is incompatible with old wallet. I noticed that size of old and new wallets is way different - 96K vs. 336K. Now I need to uninstall new wallet, to install old one, move the coins, install the new one again... Pain in the ass. I think you should notify users about this issue before they upgrade the wallet.

New wallet is compatible with old one. We tested it on Linux, FreeBSD, Windows. Usually, new emercoin-qt successfully picks up an old wallet.
Different size old/new just because of a new one has higher keypool size.

Regarding your wallet: I assume (just assume), it has been corrupted. New wallet program has more strict verification, and maybe unable work with your wallet.dat. I seen once same on BSD - one old wallet contains corrupted records. I remember, I dumped all private keys from that wallet, and upload all of them to a new one.
Theoretically, there is many ways to try repair wallet, or dump/upload keys. But this is tricky, and difficult to explain.
Thus, above I proposed rough method, which I sure will work - just move balance to a fresh wallet.

This coin is so promising and useful, why poloniex doesn't list it? Only btc38, but it can still be pumped a lot.

Because:

Look at the companies that Emercoin claim to be in partnership with:

Hashcoins - Complete & utter proven scam company who have, and continue to steal BTC100's selling vapourware to gullibles on this forum:

First Bitcoin Capital Corp. - who? after a 5 minute search I found:

https://www.otciq.com/otciq/ajax/showFinancialReportById.pdf?id=138845

..which tells me I have more capitol than they do 

I'm sure if anyone done some real research/detective work into all their "partners", they will find some common links, but I just can't be bothered - I've seen enough & won't touch anything remotely connected with emercoin & it's "team".

So, no reputable exchange will touch it.

@IconFirm

So you're saying BTC38, Bittrex, and Livecoin aren't reputable?

Please stop poking your head in here just to regurgitate the same information again and again.

[craslovell]

Can somebody help me out here.. I forgot how many words were required for the passphrase when making one??? when using the Emercoin wallet.  Or if you know how to recover lost passphrases let me know thanks.

There's no requirement, as far as I know. The password can be really any length. If you have forgotten your wallet password then you need to guess/remember it or find someone to crack it, but that may be impossible...

Unless you made a backup of the wallet.dat before encrypting the wallet...

@shutyourmouth

Emerger is right, do you have a general idea of what your passphrase may have been? If you think you know it but might have one character wrong there is a chance you can brute force your way back in. If you have no idea what it was but think it was a long password then you may be out of luck if you don't have any unencrypted copy.

Thank you how would I brute force my way in? I have the whole passphrase just dont know how many words I used lol

There are some open source programs on github you can try. One is simply called bruteforce-wallet. If you have a good idea of what it is though you may be better off just writing the variants down and guessing unless it is simply too long.

yes, i think btc38 is the most reputable exchange, no.1 altcoin exchange in China. did btc38 add you without any communication with them?

I've managed to install 0.3.7 wallet on another machine, opened old wallet without any problem and sent coins to the new empty 0.5.0 wallet. The old wallet was running 24/7 for several months and was generating POS coins, so I'm in doubts that it was corrupted. Anyway, if somebody encounter the same issue, use described procedure to save the coins.
Cheers.

When starting a new wallet, especially if using the "release candidate", I would definitely suggest making a careful backup of the wallet.dat file (shutting down emercoin before backup), and even using the dumpprivkey feature to record the private keys for a few main addresses in a safe place. I often also set keypool=1000 in the emercoin.conf, so that the wallet backup will have more addresses generated in advance, which will then be in the backup.

Release Candidate 0.5.0 for MAC ready - https://sourceforge.net/projects/emercoin/files/development/

[Fixx]

We have released new emercoin client (v0.5.0) and it is incompatible with this mmcFE pool. We are going to create new pool that is based on php-mpos - pool2.emercoin.com. This old pool will stop mining on 8 of September, 2016. It will still be open for withdrawing your emc until 30 of September, 2016.

[craslovell]

pool2.emercoin.com is running well and finding blocks. Currently only 155TH/s mining on the pool. Everyone, get your miners switched over!
