In you have been using the remote node in combination with the official Qwertycoin Desktop you may experience issues when switching back to local or automatic mode. It most cases the application will crash and a simple restart will solve the issue.

Some users report that restarting the wallet application results in yet another crash. If your get stuck in this loop don’t worry there is a simple fix using any text editor of your choice.

  1. Browse to you Qwertycoin data folder. Default on Windows is something like C:\Users\\AppData\Roaming\qwertycoin
  2. Open the GUI configuration file qwertycoinwallet.cfg using Notepad or any other editor
  3. Change the connectionMethod value to
    1. to use the Embedded node (default)
    2. to use the Local Daemon
    3. to use the configured remote node

That’s it. Start your wallet and things should be back to normal.

Qwertycoind can accept settings through a configuration file. This is the output of daemon’s help command on acceptable parameters:

all of the command line options can be defined through the configuration file.

Command line options:
  –help Produce help message
  –version Output version information
  –os-version
  –data-dir arg Specify data directory
  –config-file arg(=qwertycoin.conf) Specify configuration file
Command line options and settings options:
  –log-file arg
  –log-level arg (=0)
  –no-console Disable daemon console commands
  –rpc-bind-ip arg (=127.0.0.1)
  –rpc-bind-port arg (=8197)
  –p2p-bind-ip arg (=0.0.0.0) Interface for p2p network protocol
  –p2p-bind-port arg (=8196) Port for p2p network protocol
  –p2p-external-port arg (=0) External port for p2p network protocol (if port forwarding used with NAT)
  –allow-local-ip Allow local ip add to peer list, mostly in debug purposes
  –add-peer arg Manually add peer to local peerlist
  –add-priority-node arg Specify list of peers to connect to and attempt to keep the connection open
  –add-exclusive-node arg Specify list of peers to connect to and attempt to keep the connection open
  –seed-node arg Connect to a node to retrieve peer addresses, and disconnect
  –hide-my-port Do not announce yourself as peerlist candidate
  –extra-messages-file arg Specify file for extra messages to include into coinbase transactions
  –start-mining arg Specify wallet address to mining for
  –mining-threads arg Specify mining threads count

If a parameter is defined in the config and was also indicated in the command line, two behaviors are possible. If the parameter accepts one value only (e.g., rpc-bind-ip), the command line value will be used, since it has a higher priority. If the parameter accepts several values (e.g., add-priority-node), then command line and configuration file values will be merged.

By default config file’s name is “qwertycoin.conf”, which is located in the binaries folder. However, you may adjust the destination to the file via “–config-file” option in the command line.

If some of the options are not defined in the config, the default values will be applied. Here’s the example of a possible configuration file:

log-level=4
no-console=yes

rpc-bind-ip=0.0.0.0
rpc-bind-port=8197
p2p-bind-ip=0.0.0.0
p2p-bind-port=8196
p2p-external-port=81960

allow-local-ip=yes

add-peer=1.1.1.1:8196
add-peer=1.1.1.2:8196
add-peer=1.1.1.3:8196

seed-node=2.2.2.2:8197
seed-node=2.2.2.2:8197

hide-my-port=no

start-mining=QWC1L4aAh5i7cbB813RQpsKP6pHXT2ymrbQCwQnQ3DC4QiyuhBUZw8dhAaFp8wH1Do6J9Lmim6ePv1SYFYs97yNV2xvSbTGc7s
mining-threads=4

To synchronize your Qwertycoin software with the network faster, you may download blockchain file.

  1. Unpack the downloaded blockchain archive.
  2. Move the extracted files blockindexes.dat and blocks.dat to the standard Qwertycoin folder (replace existing files if necessary):

Windows:

C:\Users\%user_name%\AppData\Roaming\qwertycoin\

OSX/Linux:

~/.qwertycoin/

Relaunch your Qwertycoin software.

Qwertycoin works through 2 separate binary files operated through command line:

  1. qwertycoind– daemon to synchronize the blockchain and mine qwertycoin.
  2. simplewallet – wallet to receive and send funds.

Install Qwertycoin

  1. Unzip the archive to one separate folder
  2. Download blockchain archive and unpack it to:

Windows:

C:\Users\%user_name%\AppData\Roaming\qwertycoin\

OSX/Linux:

~/.qwertycoin/

Launch Qwertycoin

  1. Open qwertycoind. For downloadable Linux archive use ./qwertycoind.
  2. Wait until qwertycoind is synchronized. You will be notified with several green “SYNCHRONIZED OK” messages.
  3. Open simplewallet. For downloadable Linux archive use ./simplewallet.

Daemon: synchronization & mining

After qwertycoind is launched you will have to wait until it is synchronized with the network. You will be notified with several green “SYNCHRONIZED OK” messages. Here are the most important daemon commands:

start_mining [threads=1] Start mining in several threads to a given wallet address
stop_mining Stop mining
show_hr Show current mining hashrate
hide_hr Stop showing current mining hashrate
help Show all daemon commands
exit Exit qwertycoind

Wallet: send and receive payments

Simplewallet can only be used after the daemon is launched and synchronized. Simplewallet automatically synchronizes with qwertycoind. Here are the most important wallet commands:

address Show your wallet address
balance Show current wallet balance
transfer

Send money to

with a mixing amount of
start_mining Start mining in daemon with several threads to the current wallet address
stop_mining Stop mining in daemon
help Show all wallet commands
exit Exit simplewallet

Once you open Qwertycoin Wallet, it will automatically create your first Qwertycoin address and start synchronizing with the network.

It is highly recommended that you encrypt your new wallet with a password. Leaving the wallet unprotected makes it vulnerable in case your system is compromised.

To encrypt your wallet, choose “Settings” menu and then “Encrypt wallet”.

Wallet file format

Unlike Qwertycoin Reference Client, Qwertycoin Wallet uses .wallet files instead of legacy .keys files to store your private keys for each wallet.

Qwertycoin Wallet is able to import .keys files (with the existing password), but it will create a .wallet file for further operations.

Qwertycoin Wallet files

Qwertycoin Wallet introduces several new files stored in the standard Qwertycoin folder:

Windows:

C:\Users\%user_name%\AppData\Roaming\qwertycoin\

OSX/Linux:

 ~/.qwertycoin/

The most commonly used files are the following:

  • qwertycoinwallet.wallet – a default wallet keys file that is created on first startup of Qwertycoin wallet and gives access to your fresh Qwertycoin address.
  • qwertycoinwallet.log – a log file for the node that is running inside Qwertycoin Wallet.

Import your Paperwallet into Desktop Wallet with only a few clicks:

You Need:

Your paperwallet generated “Keys for GUI Wallet” to complete these Tutorial.

1. Open Qwertycoin Wallet and go to “File > Import private key“.

2. Paste here your “Keys for GUI Wallet”-key into these Popup and set your location where you wanna store your converted Walletfile.

If you set all click on OK

Done

Desktop Wallet is now available.

Just go to Download Section and click on the specific Downloadlink for your Operationsystem.

Cryptonote coin’s wallets can operate through remote daemon without downloading blockchain. It allows to start working quickly when needed. It is quite safe as remote daemon can’t steal your coins, running own node is more secure of course. But these remote nodes are not rewarded anyhow in any CN coin.

So, basically, Masternode it is the CLI Qwertycoin daemon running on a machine with open port which allows to connect to it for such light wallets and, most important, mobile wallets in the future. Qwertycoin wallets, connected to Masternode, are paying small fees to that node when are sending transactions through it. These fees are supposed to help to cover the costs of operating Qwertycoin nodes.

These Masternodes are providing service necessary for mobile wallets, and besides are helping to maintain and enlarge Qwertycoin network. We have plans no incentivize such nodes even more in the future.

To start own Qwertycoin masternode all is needed is just a machine with static IP and open port. Machine should have enough CPU power to handle load when parsing blockchain for connected wallets, it can be even spare PC at home. On such machine you can run qwertycoin daemon specifying a wallet address where fees would go like this:

./qwertycoind --restricted-rpc --enable-cors=* --enable-blockchain-indexes --rpc-bind-ip=0.0.0.0 --rpc-bind-port=8197 --fee-address=QWC1L4aAh5i7cbB813RQpsKP6pHXT2ymrbQCwQnQ3DC4QiyuhBUZw8dhAaFp8wH1Do6J9Lmim6ePv1SYFYs97yNV2xvSbTGc7s

You can specify any wallet address, it can be your GUI wallet address, even paper wallet. This is the wallet where you will receive fees.
You need to make sure your port is open and not blocked by firewall. If you are running it at home behind router you need to do port forwarding.

If you have PC at home constantly running with fast connection and static IP and want to operate such Masternode to help Qwertycoin network, run daemon as in example and send ous your IP so We can add it do default nodes list.
You can check if your node is running opening its IP in browser like this

http://78.47.85.215:8197/feeaddress

and you should see something like this

{"fee_address":"QWC1L4aAh5i7cbB813RQpsKP6pHXT2ymrbQCwQnQ3DC4QiyuhBUZw8dhAaFp8wH1Do6J9Lmim6ePv1SYFYs97yNV2xvSbTGc7s","status":"OK"}

with your wallet address where fees should go.

You can also run Masternode on VPS with dedicated domain and publish here with description so people can add your node manually if they prefer it. It is not recommended to run node on VPS now specially for Qwertycoin, do it only when you already have spare VPS and it is idling.
For now, do not expect yet to earn a lot of fees because there is very low usage of such remote nodes.
