VTC almost $4 on Bittrex. Always liked this old coin, same as I do BLK. Have to take a look again for this Project.

forum website looks nothing useful there. I wonder why you include that in Post. It also not forum.. site also saying it is wordpress blog.

Hello, developers!
I see you have paperwallet here: https://github.com/vertcoin/paperwallet
but when i did download it and open it, I see there is generated private key beginning from "7"!..
I cann't import this private key to my qt-wallet using console command importprivkey "private_key"
and I cann't get the compressed compressed private key and compressed address
from uncompressed private key, that's beginning from "7" in the section "Wallet Details".
I see an error there:
"The text you entered is not a valid Private Key!
Would you like to use the entered text as a passphrase
and create a Private Key using a SHA256 hash of the passphrase?
Warning: Choosing a strong passphrase is important to avoid brute force
attempts to guess your passphrase and steal your Vertcoins."

I have some vertcoins in paperwallet address, and I see it in block explorer,
but I cann't get access to this funds now, because incorrect private key format in this paperwallet.
Also i used walletgenerator.net, with option Vertcoin: https://walletgenerator.net/?currency=Vertcoin
There I can translate uncompressed private key to compressed,
but then if I will import compressed private key
will I get access to COMPRESSED address, not uncompressed!

I think you need to delete paperwallets, set up correctly their source codes, test it and publish again.
I have private key but I lost vertcoins and don't know what to do now...  


P.S.:
I did test again import of private keys from https://github.com/vertcoin/paperwallet
and I see that is compressed address I cann't import too, like an uncompressed.
Uncompressed private keys cann't be impoted.

Also, using console command dumpprivkey VTC_address,
I see that is private keys that was been generated in vertcoin-qt are beginning from K, and L.
That means you need to fix this:
ECKey.privateKeyPrefix = 0xC7; // vertcoin privkey prefix is 199 decimal (71+128)
to this
ECKey.privateKeyPrefix = 0x80; // [K,L] the first prefix symbol of compressed private key
and this
Bitcoin.Address.networkVersion = 0x00; // testnet isn't enabled
Bitcoin.ECKey.privateKeyPrefix = 0x00; // testnet isn't enabled
to
Bitcoin.Address.networkVersion = 0x47; // "V" first symbol prefix in address
Bitcoin.ECKey.privateKeyPrefix = 0x80; // [K,L] first symbol prefix in compressed private key

Also, as I see after this changes of the source of paperwallet,
there is generating umcompressed private key (beginning from 5) and address.
That means need to compress it both.
Remember this:
1. Compressed pub have only 1 coordinate x.
2. Compressed private key have 0x01 in last.

After some tests and changing of source code I got success for generate and import private keys.
Also, I have on my hard disk walletgenerator and brainwalletx from SIGNATUM.
There is also using compressed private keys, so I just did change it for Vertcoin.
You can download it and test it here:
Paperwallet: [LINK] WalletGenerator.net-VTC.zip
Brainwallet, Armory, Electum, signing an verify message: [LINK] brainwalletX.github.io-VTC.zip
All changes in the comments of the source code. Files will be deleted after 90 days automatically.
You can re-write it and insert your pictures.

Best regards... And... You can donate me some VTC: VpZm33PBxS1iW7W4yaPrFBtGuA7wTh8gpu

How would you import the VTC into electrum?  I have the same issue with syncing as previous poster.  Is it as simple as dumping the private keys from the console - then importing into electrum (even though wallet hasn't synced)?

Hi, I haven't used my VTC wallet for a while and it's out of date.  I downloaded the latest wallet to Sync but not syncing, followed a suggestion to download the bootstrap file. Now it is syncing from local bootstrap, but has got stuck at December 13th 2014, and is not moving.  Any ideas? Also there are zero active connections to the vertcoin network.  Running Vertcoin Core version v0.11.1.0-9c5018b (64-bit)

Had the same issue on linux. I suggest using the electrum client, works perfectly on both win and linux. Who wants do d/l 3 years of chain anyway?

Wow, VTC continues to rise, even btc rises. I hope this rise never ends. It encountered some blockade, yet, it still continue to rise.
