Terracoin Core Wallet

Whenever you are storing objects with a market value, security is necessary. This applies to barter systems as well as economies using currency as a medium of exchange. While banks store balances on a private ledger, cryptocurrencies store balances under unique addresses on a distributed public ledger. The cryptographic private keys to access the balance stored on each public address are therefore the object of value in this system. This section of the documentation discusses different practical methods of keeping these keys safe in wallets, while still remaining useful for day-to-day needs.

The Terracoin Core Wallet is the full official release supporting all Terracoin features as they are released, including InstantSend and PrivateSend, as well as the governance, masternode and voting features. It is identical to the software used by the Terracoin masternodes, and as such, it requires you to download the entire Terracoin blockchain. It is available for macOS, Linux, and Windows.

Introduction to Terracoin Core

This documentation describes the Terracoin Core Wallet and how to use its basic functions. Since the functionality is similar across all supported platforms (Windows, macOS, Linux), the instructions and screenshots will reference the Windows software, highlighting differences between the platforms where necessary. See here for separate installation guides specific to each platform.

The Terracoin Core Wallet (sometimes known as the QT wallet, due to the QT software framework used in development) is a professional or heavy wallet which downloads the full blockchain (several GB in size), operates as a full node on the network and offers all functions available to Terracoin. When the wallet starts up, some time is required for it to synchronise its copy of the blockchain with the network. Once this is done, the correct balances will be displayed and the functions in the wallet can be used.

Features:

PrivateSend
InstandSend
Wallet encryption
Coin control and fee control
QR code generation and address book
Masternode commands and voting
Automated backup
Debug console

Installation

Terracoin Core can be compiled from source or downloaded for Linux, macOS and Windows here. Full installation guides are available here.

The Main Window

The Terracoin Core Wallet is an application that runs on your computer and allows you to make transactions on the Terracoin network. Most transactions are for sending or receiving Terracoin, but it is also possible to create signed messages or control a masternode, for example.

The Terracoin Core window is broken up into several areas:

The menu bar
The tab bar
The main area
The status bar

Terracoin Core Main Window

The Menu Bar

The menu bar provides access to all functions of Terracoin Core. There are four menus available:

File: The File menu is used to manage your wallet, messages and addresses.
Settings: The Settings menu provides access to wallet encryption options and general software settings.
Tools: The Tools menu provides information on the network, allows you modify masternode configuration files and other advanced functions.
Help: The Help menu links to documentation, guides and legal statements relating to Terracoin Core.

The Tab Bar

The tab bar is used to quickly switch between the main areas of the Terracoin Core. The content in the main area of Terracoin Core changes depending on which tab you have selected. The following tabs are available:

The Overview tab

The overview tab offers quick access to your balance and most recent transactions, as well as the PrivateSend feature and options for coin mixing.

Terracoin Core Overview Tab

The left part of the main area is divided into two areas. The upper area shows your balances:

Available: This shows your current liquid balance. This is the amount of Terracoin you can spend now.
Pending: This shows funds waiting for a transaction to complete.
Immature: This shows funds from masternode or mining payments which have not yet reached the required number of confirmations.
Total: This is simply your available and pending funds added together.

The lower area shows the status of PrivateSend and allows you to mix your funds using the Terracoin Masternode Network.

The right part of the screen shows your recent transactions. These are identified by icons as follows:

Recent incoming transactions appear black, prefixed by a + sign

Recent outgoing transactions appear red, prefixed by a – sign

Incoming mining or masternode payments also appear black

For more details on your transaction history, see the Transactions tab.

The Send Tab

The Send tab allows you to send funds to another address on the Terracoin network. It contains fields to enter the recipient’s address, a label for the address, and the amount of Terracoin you wish to send. Options related to the transaction fee, InstantSend and PrivateSend are also available. A quick view of your total balance is also available in the lower right corner.

Terracoin Core Send Tab

The Receive Tab

The Receive tab allows you to create addresses to receive Terracoin. You can create a request for a specific amount of Terracoin or include a specific message, and send it to another user as a link or QR code.

Terracoin Core Receive Tab

The Transactions Tab

The transactions tab shows the entire transaction history for all addresses associated with your wallet. This appears as a table showing the time, type, label and amount of Terracoin for each transaction. You can also export the transaction history as a CSV file by clicking the Export button in the bottom right corner of the window.

The icons in the leftmost column indicate the status of the transaction. A tick indicates that the recommended number of confirmations has been passed, while a clock indicates that the transaction has yet to reach six confirmations.

Terracoin Core Transactions Tab

The Status Bar

The status bar shows a synchronization progress bar and a row of status icons which indicate the status of your connection to the Terracoin network.

The Synchronization Area

This bar shows the synchronization status of Terracoin Core with the Terracoin network. Each time you open Terracoin Core, it will begin downloading the blocks which have been created on the blockchain in the time since you last opened the app. These blocks are downloaded from other Terracoin users and masternodes. If you have never opened the app before, this could mean several years' worth of blocks need downloading. The following statuses are possible:

No block source available: This occurs if your internet connection is down, or if the ports required by Terracoin Core are blocked by a firewall.
Synchronizing with network: Terracoin Core is downloading blocks from the network.
Synchronizing masternodes/masternode payments/governance objects: Terracoin Core is synchronizing other data with the second layer network.

Once synchronization is complete, the progress bar will disappear and a tick will appear on the right of the status bar.

The Status Icons

The lock icons indicate the status of your wallet: either locked or unlocked. You need to unlock your wallet to send funds or perform certain other actions.

These icons indicate the quality of your connection to the Terracoin network. If you cannot connect because of network problems, you will see the icon on the left. More bars indicate more connections to your peers on the network.

These icons show the synchronization status of Terracoin Core with the network. Once synchronization is complete, the refresh icon will become a blue tick.

Terracoin Core Options

This documentation describes the functionality of the Terracoin Core Options dialog, available under the Settings > Options menu in Terracoin Core.

Main

The Main tab of the Options dialog contains settings related to startup and performance of the Terracoin Core app.

The Main tab of the Terracoin Core Options dialog

Start Terracoin Core on system login

This option causes Terracoin Core to start automatically when the current user logs in. On most computers there is only one main user account which is logged in automatically when the computer turns on, so this option is effectively the same as starting Terracoin Core together with the operating system.

Size of database cache

This option specifies the size of the database cache in memory. A higher value will result in increased performance when adding new blocks at the cost of higher memory usage. The default value is 100MB and it should not be set lower than this level.

Number of script verification threads

This option sets the number of script verification threads, ranging from -4 to 16. Script verification is the process of following instructions recorded in the blockchain to ensure the transactions are valid. 0 means automatic and will allow script verification to scale to the number of cores available on your processor. Setting a positive number specifies that Terracoin Core should use that number of processor cores, while setting a negative number will leave that number of processor cores free.

Wallet

The Wallet tab of the Options dialog contains settings related to how addresses are managed in the Terracoin Core app. The first time you run Terracoin Core, it will generate a new wallet containing 1000 unique Terracoin addresses. This tab allows you to configure how these addresses are used as inputs with the Coin Control, PrivateSend and Masternode features.

The Wallet tab of the Terracoin Core Options dialog

Enable coin control features

Your Terracoin Core wallet balance is actually the sum total of all addresses holding balance that are associated with your wallet. When you spend Terracoin, Terracoin Core will withdraw from as many inputs as necessary to make up the desired amount of Terracoin to be transferred. This behavior may be undesirable if you want to keep a certain balance on one address. The most common use case is the requirement to maintain 5000 Terracoin on a single address as collateral for a masternode.

Enabling this option will add a button labelled Inputs on the Send tab. This provides access to the Coin selection dialog, which can be used to lock, unlock and prioritize different addresses in your wallet. See here for a more detailed explanation of Coin Control.

Show Masternodes tab

Enabling this option causes Terracoin Core to display an additional Masternodes tab to the right of the Transactions tab. This option requires you to restart the Terracoin Core app.

The Masternodes tab can be used to manage interactions (start, stop, check status, etc.) with masternodes controlled by this wallet. This tab is an advanced feature not required by users that do not operate a masternode on the Terracoin network. See here for a description of the Masternodes tab.

Enable advanced PrivateSend interface

Enabling this option changes the PrivateSend mixing interface on the Overview tab of the Terracoin Core wallet to include more options, such as Try Mix and percentage completion. See here for a full explanation of how to use PrivateSend.

Warn if PrivateSend is running out of keys

Enabling this option will cause Terracoin Core to display a warning when your original set of 1000 addresses is running out, which may affect PrivateSend mixing. Every time a mixing event happens, up to 9 of your addresses are used up. This means those 1000 addresses last for about 100 mixing events. When 900 of them are used, your wallet must create more addresses. It can only do this, however, if you have automatic backups enabled. Consequently, users who have backups disabled will also have PrivateSend disabled.

Enable PrivateSend multi-session

Normally PrivateSend mixing is completed in several consecutive rounds, each using a single masternode. Enabling this option allows multi-session, which means you can use multiple masternode servers at the same time, greatly increasing the speed of the mixing process at the cost of creating more addresses and thus requiring more frequent wallet backups. This feature is experimental as of Terracoin Core 12.1.7.

Spend unconfirmed change

When this option is enabled, the Terracoin Core wallet permits you to immediately spend change from previous transactions that has been transferred internally between addresses associated with the same wallet. This is possible even if the transaction has not yet been confirmed because the wallet knows it will eventually be confirmed since it created the internal transaction itself. Leaving this option enabled allows you to create new transactions even if previous transactions have not yet been confirmed.

PrivateSend rounds to use

Use this option to control the number of rounds of PrivateSend mixing to be carried out for your chosen balance. Each round of mixing uses a new masternode. The higher the number of rounds, the more difficult it becomes to trace the Terracoin to its original address. This is at the expense of more time required for mixing and potentially higher fees. See here for a full explanation of how to use PrivateSend.

Amount of Terracoin to keep anonymized

This option allows you to specify how much Terracoin should be kept on balance in a ready-to-use anonymized state, meaning it has already passed through the PrivateSend mixing process. If you do not have sufficient Terracoin available in your balance of unlocked inputs, the amount will be automatically reduced to the available balance and shown in red in the PrivateSend interface on the Overview tab.

Network tab

This tab includes options related to how your connection to the Terracoin network is made.

The Network tab of the Terracoin Core Options dialog

Map port using UPnP

This option causes Terracoin Core to automatically attempt to open and map the client port on your router using UPnP (Universal Plug and Play). This feature is supported by most modern home routers and will allow you to connect to the Terracoin network without making any special settings on your router.

Allow incoming connections

This option causes your client to accept external connections. Since Terracoin is a peer-to-peer network and Terracoin Core is considered a full client because it stores a copy of the blockchain on your device, enabling this option helps other clients synchronize the blockchain and network through your node.

Connect through SOCKS5 proxy (default proxy)

These options allow users on an intranet requiring a proxy to reach the broader internet to specify the address of their proxy server to relay requests to the internet. Contact your system administrator or check out the network settings in your web browser if you are unable to connect and suspect a proxy may be the source of the problem.

Use separate SOCKS5 proxy to reach peers via Tor hidden services

These options allow you to specify an additional proxy server designed to help you connect to peers on the Tor network. This is an advanced option for increased privacy and requires a Tor proxy on your network. For more information about Tor, see here.

Window tab

This option contains options governing behavior of the Terracoin Core app window under Microsoft Windows.

The Window tab of the Terracoin Core Options dialog

Hide tray icon

When this option is enabled, Terracoin Core will not display an icon in the system tray. This option cannot be selected at the same time as Minimize to the tray instead of the taskbar.

Minimize to the tray instead of the taskbar

When this option is enabled and the Terracoin Core window is minimized, it will no longer appear in your taskbar as a running task. Instead, Terracoin Core will keep running in the background and can be re-opened from the Terracoin icon in the system tray (the area next to your system clock). This option cannot be selected at the same time as Hide tray icon.

Minimize on close

When this option is enabled, clicking the X button in the top right corner of the window will cause Terracoin Core to minimize rather than close. To completely close the app, select File > Exit.

Display tab

This tab contains options relating to the appearance of the Terracoin Core app window.

The Display tab of the Terracoin Core Options dialog

User interface language

Select your preferred language from this drop-down menu. Changing the language requires you to restart the Terracoin Core app. Terracoin Core currently offers translations in Bulgarian, German, English, Spanish, Finnish, French, Italian, Japanese, Polish, Portuguese (Brazil), Russian, Slovenian, Swedish, Vietnamese, Simplified Chinese and Traditional Chinese.

User interface theme

You can use this option to select a different theme governing the appearance of the Terracoin Core window. All functionality is identical under the different themes, although the default Terracoin-light theme is most recent and most likely to work without any display artifacts.

Unit to show amounts in

This allows you to change the default unit of currency in Terracoin Core from TRC to mTRC, µTRC or duffs. Each unit shifts the decimal separator three places to the right. Duffs are the smallest unit into which Terracoin may be separated.

Decimal digits

This option allows you to select how many decimal digits will be displayed in the user interface. This does not affect internal accounting of your inputs and balance.

Third party transaction URLs

This option allows you to specify and external website to inspect a particular address or transaction on the blockchain. Several blockchain explorers are available for this. To use this feature, enter the URL of your favorite blockchain explorer, replacing the %s with the transaction ID. You will then be able to access this blockchain explorer directly from Terracoin Core using the context menu of any given transaction.

Terracoin Core Tools

This documentation describes the functionality of theTerracoin Core Tools dialog, available under the Tools menu in Terracoin Core.

Information

The Information tab of the Tools dialog contains information related to the software and network.

The Information tab of the Terracoin Core Tools dialog

General

This section displays information on the name and version of the client and database, and the location of the current application data directory.

Network

This section displays information and statistics on the network to which you are connected.

Block chain

This section shows the current status of the blockchain.

Memory pool

This section shows the status of the memory pool, which contains transactions that could not yet be written to a block. This includes both transactions created since the last block and transactions which could not be entered in the last block because it was full.

Open debug log file

This button opens debug.log from the application data directory. This file contains output from Terracoin Core which may help to diagnose errors.

Console

The Console window provides an interface with the Terracoin Core RPC (remote procedure call) console. This is equivalent to the terracoin-cli command on headless versions of Terracoin, such as terracoind running on a masternode. Click the red – icon to clear the console, and see the detailed documentation on RPC commands to learn about the possible commands you can issue.

The Console tab of the Terracoin Core Tools dialog

Network Traffic

The Network Traffic tab shows a graph of traffic sent and received to peers on the network over time. You can adjust the time period using the slider or Clear the graph.

The Network Traffic tab of the Terracoin Core Tools dialog

Peers

The Peers tab shows a list of other full nodes connected to your Terracoin Core client. The IP address, version and ping time are visible. Selecting a peer shows additional information on the data exchanged with that peer.

The Peers tab of the Terracoin Core Tools dialog

Wallet Repair

The Wallet Repair tab offers a range of startup commands to restore a wallet to a functional state. Selecting any of these commands will restart Terracoin Core with the specified command-line option.

The Wallet Repair tab of the Terracoin Core Tools dialog

Salvage wallet

Salvage wallet assumes wallet.dat is corrupted and cannot be read. It makes a copy of wallet.dat to wallet.<date>.bak and scans it to attempt to recover any private keys. Check your debug.log file after running salvage wallet and look for lines beginning with "Salvage" for more information on operations completed.

Rescan blockchain files

Rescans the already downloaded blockchain for any transactions affecting accounts contained in the wallet. This may be necessary if you replace your wallet.dat file with a different wallet or a backup - the wallet logic will not know about these transactions, so a rescan is necessary to determine balances.

Recover transactions

The recover transactions commands can be used to remove unconfirmed transactions from the memory pool. Your wallet will restart and rescan the blockchain, recovering existing transactions and removing unconfirmed transactions. Transactions may become stuck in an unconfirmed state if there is a conflict in protocol versions on the network during PrivateSend mixing, for example, or if a transaction is sent with insufficient fees when blocks are full.

Upgrade wallet format

This command is available for very old wallets where an upgrade to the wallet version is required in addition to an update to the wallet software. You can view your current wallet version by running the getinfo command in the console.

Rebuild index

Discards the current blockchain and chainstate indexes (the database of unspent transaction outputs) and rebuilds it from existing block files. This can be useful to recover missing or stuck balances.

How to send and receive Terracoin

Transactions

Your Terracoin Core Wallet is associated with a number of unique addresses that can be used to send and receive TRC. Each address holds its own balance, and the sum of all your balances is what appears on the Overview tab. When you send Terracoin, your wallet will automatically transfer funds from as many of your addresses as necessary to the destination address, which is controlled by another Terracoin user and associated with their wallet. You can control which addresses you use using the Coin Control feature.

When you confirm a transaction, Terracoin Core will enter the transaction in a block, which will then be added to the blockchain for other clients to confirm. A transaction is generally considered confirmed once six blocks have been added after the block containing your transaction, although masternode and mining payments are only released after 101 blocks. Note that a different process is used for InstantSend and PrivateSend transactions.

Terracoin addresses are 34 characters long and begin with a 1.

Sending Terracoin

You can use Terracoin Core to send Terracoin from your balance to another user. The receiving user will provide you with a Terracoin address to which you should send the funds. Click the Send tab in the tab bar and enter the destination address in the Pay To field.

The Terracoin Core Send tab

You can also use the three icons to the right of the Pay To field to select a previously used address, paste an address from the clipboard, or clear the current address. If this is a new address, you can enter a name for the address in the Label field to help identify it again later. Finally, enter the amount of Terracoin you want to transfer in the Amount field.

The other options relate to fees and PrivateSend/InstantSend. You can choose if you want to pay the network fee in addition to the amount sent, or subtract it from the amount sent. You can also increase your fee to encourage nodes on the network to prioritize your transaction. Choosing InstantSend has a similar effect, but actually relies on a different mechanism in the second layer network to speed up the transaction time. You can read more about InstantSend here. Choosing PrivateSend will send Terracoin from an address that has previously been mixed. You can find out more about PrivateSend and mixing here.

Let’s try an example. Say you have decided to donation 5 TRC to the Terracoin Foundation.

The Send tab filled out for a transaction

Once you have entered the destination address and the amount, click the Send button. If you have encrypted your wallet, you will now be required to enter your password to unlock the wallet.

Entering the password to unlock the wallet

Finally, you are given one final confirmation and chance to cancel your send transaction before Terracoin Core processes the transaction on the blockchain.

Final confirmation window

If you respond with Yes, your transaction will be processed. Your operating system may display a notification, and the transaction will appear on the Transactions tab, where you can monitor its progress.

The Windows 10 sent transaction confirmation notification

Note that the amount of the transaction increased by .00007460 Terracoin. This is the transaction fee. In the next section, we will see what this procedure looks like from the receiving side.

Receiving Terracoin

To receive Terracoin, you must first create a receiving address to give to the sending party. To do this, click File > Receiving addresses. The Receiving addresses window appears.

The Receiving addresses window

Either copy an existing address by clicking on the address and then the Copy button, or create a new address by clicking the New button. You can also edit an existing address by right clicking and selecting Edit address from the context menu. Give this address to the person who will send you Terracoin. Your wallet does not need to be open to receive funds, but if it is, you can watch the transaction arrive in real time. This is because your wallet constantly watches for new blocks on the blockchain when it is open, and will recognize a new transaction involving your receiving address when it occurs.

The Windows 10 received transaction confirmation notification

Once you have been paid, you can see the balance both on the Overview tab and on the Transactions tab.

How to use PrivateSend

Below describes how to use the Terracoin client to run PrivateSend and anonymize your Terracoin. PrivateSend, rebranded from DarkSend in May 2016, is a trustless method of running a sequence of transactions such that an external observer is unable to determine the source of funding when a PrivateSend transaction is created. This gives your Terracoin the same anonymous properties as cash withdrawn from an ATM, for example. By using this software, you agree not to use it for illegal purposes and that you are solely responsible for any lost Terracoin.

Introduction to PrivateSend

With the introduction of Release Candidate 4 (RC4) of the Darkcoin client, it became possible to store pre-mixed, denominated Terracoin in the user’s wallet, to be used instantly at any time the user desires. The mixing and denomination process is seamless, automatic, and requires no intervention on the part of the user. The current implementation of PrivateSend in the Terracoin Core wallet allows any amount of Terracoin to be mixed for later use in PrivateSend transactions.

Here's how it works:

Every 10 blocks, user clients network-wide will send any unmixed, traceable Terracoin in their possession through an anonymization phase. In this phase, masternodes are used in chained succession to mix the coins they receive from the network and break them down into homogenous denominations.
After being processed by a minimum of 2 masternodes, the coins are either sent to the next masternode in the chain or back to the user’s wallet at randomly generated change addresses.
Depending on the desired depth of security and privacy, users may select between 2 and 8 “hops” to successive masternodes before their coins are sent back to the client. Hops are made every 10 blocks, so anonymization at a depth of 2 hops will take 2*2.5=5.0 minutes, 3 hops 3*2.5=7.5 minutes, and so on. The desired mixing depth can be selected in the client GUI.
At the end of the anonymization phase, the user’s coins are returned to their client at randomly generated change addresses. When the user wishes to make a transaction, the client forwards the intended amount from these anonymous change addresses directly to the intended receiver’s address. There is no direct involvement of of masternodes in the final person-to-person transaction.
Proof of payment will work as it always has: a user can see the send transaction with the receiver’s address in their own wallet, and the blockchain will show that the receiver’s address received an input in the corresponding amount.

Setting default PrivateSend options

1. Open your Terracoin Core wallet, go to Settings and select Options. Go to the Wallet tab.

Terracoin Options Wallet PrivateSend Advanced

2. Next to PrivateSend rounds to use, enter a value between 1-8.

Each round of PrivateSend performs one denominated fund mixing transaction. Higher numbers of rounds increase your overall level of anonymity while decreasing the chance of detection via node collusion. 8 is the highest number of rounds currently available.

NOTE: each round of PrivateSend includes a masternode fee of 0.0125 Terracoin.

3. Enter a target value for Amount of Terracoin to keep anonymized.

This value provides a lower boundary on the final amount of funds to be anonymized. Depending on how the client splits your wallet balance, you may end up with denominated inputs whose sum total is greater than the target amount. In this case the client will use all existing denominated inputs in the PrivateSend process. The final anonymized amount may be higher than your target, but should be close.

4. Click OK to save settings.

5. PrivateSend is disabled by default when you open the wallet. It will only start after you set the number of rounds and number of Terracoin to mix under settings and click Start Mixing on the Overview tab of your wallet.

Initiating the PrivateSend process

The PrivateSend process is initiated by clicking the Start Mixing button on the Overview tab of the Terracoin Core wallet. Mixing is possible once the following conditions have been met:

The wallet contains sufficient non-anonymized funds to create the minimum required denominated values The user has not disabled PrivateSend in the Options dialog The target value for anonymized Funds in the Options dialog is greater than zero If your wallet is encrypted (highly recommended), you will be asked to enter your wallet passphrase. Enable the Only for mixing via PrivateSend checkbox to unlock the wallet for mixing only.

Entering a password for PrivateSend mixing only

This will unlock your wallet, and the PrivateSend mixing process will begin. The wallet will remain unlocked until PrivateSend mixing is complete, at which point it will be locked automatically.

PrivateSend interface after clicking the Start Mixing button. Note the Status is Enabled.

PrivateSend will begin creating transactions and your PrivateSend balance will gradually increase. This process can take some time, so be patient. You can monitor the process in more detail as described here.

Any of the following actions will interrupt the mixing process. Because the transactions are atomic (they either take place completely, or do not take place at all), it should be possible to safely interrupt PrivateSend mixing at any time.

Clicking the Stop Mixing button on the Overview tab Closing the client before PrivateSend mixing is completed Sending PrivateSend funds from the wallet before PrivateSend rounds are completed Disabling PrivateSend before the process is complete

Monitoring PrivateSend progress

If you want to monitor PrivateSend in more detail, you need to enable some advanced features of the wallet. Go to Settings, select Options and go to the Wallet tab. Check the boxes next to the Enable coin control features and Enable advanced PrivateSend interface options.

Enabling advanced options for PrivateSend in the Terracoin Core wallet settings

This will allow you to monitor progress and see which individual operations PrivateSend is carrying out in the background.

Monitoring PrivateSend progress

This will allow you to monitor progress and see which individual operations PrivateSend is carrying out in the background.

Since PrivateSend mixing creates a lot of new address keys to send and receive the anonymized denominations, you may receive a warning when the number of remaining keys runs low. This is nothing to be worried about, since the wallet will simply create more keys as necessary. However, these keys will not exist in any previous backups of your wallet. For this reason, it is important to backup your wallet again after mixing is complete.

You can also monitor PrivateSend progress by viewing the transactions created by the mixing process on the Transactions tab.

Transactions created by PrivateSend on the Transactions tab

You can also use the coin control feature to view which addresses hold mixed denominations ready to be used for PrivateSend transactions. Go to the Send tab of your wallet and click Inputs to view the possible input addresses for your transactions. You can see how each address holds given denominations of mixed Terracoin, and how many rounds of mixing have been completed. This is to ensure that an efficient combination of addresses can be used as inputs in PrivateSend transactions without too much change, since amount in a PrivateSend transaction must be rounded up to completely spend all inputs. The current minimum balance for an input used in a PrivateSend transaction is 0.01000010 Terracoin.

Sending payments with PrivateSend

You can only use PrivateSend for payments once you have mixed enough Terracoin to make up the amount you are trying to send. Because the mixing process takes time, it must be done in advance before you create the send transaction. A PrivateSend transaction is effectively the same as any other transaction on the blockchain, but it draws only from input addresses where the denomination has previously been mixed to ensure anonymity of funds. Because several input addresses are usually required to make up the amount you are trying to send, a PrivateSend transaction will usually take up more space (in kilobytes) on the blockchain, and therefore will be charged a slightly higher fee. To send a payment using PrivateSend, go to the Send tab of the Terracoin Core wallet and enable the PrivateSend option. The balance displayed will change to show your PrivateSend balance instead of the total balance. You can then enter the Pay To address, Label, Amount and click Send as usual. Your payment will be rounded up to completely spend the lowest possible denomination of mixed balance available (currently to the nearest 0.01 TRC). You will be prompted to enter your password and receive a detailed breakdown of the fee structure for PrivateSend before sending.

How to safely back up your wallet

Introduction

This documentation describes how to safely back up your wallet file for safe storage in case your computer or laptop is damaged or lost. Terracoin Core stores all data necessary to control your Terracoin addresses in a single file called wallet.dat. This wallet is in the Berkeley DB format and stores the pairs of private/public cryptographic keys used to manage your balances on the Terracoin blockchain. Terracoin Core makes most of these operations transparent and even generates automatic backups of your wallet file in case it is corrupted, but the user is responsible for ensuring that these backups are stored in a safe place. If you lose access to these key pairs, you will permanently lose access to your Terracoin.

It is important to consider that if you have not encrypted your wallet using the Settings > Encrypt Wallet menu item, anyone with access to the backed up wallet.dat file will immediately have full access to your Terracoin. If you do choose to encrypt your wallet, do not store the password in the same place as the wallet.dat file, particularly if you are saving the backup to the cloud.

Backing up your wallet

Backing up from Terracoin Core

Firstly, never copy your wallet.dat file while Terracoin Core is open. Always use the File > Backup Wallet menu if the wallet is open. When you select this menu item, a dialog box will appear to specify where the file should be saved. Enter a name for the file, select a location and click Save. The example below shows saving the file to a USB stick. Keep this file in a physically separate location to your computer.

Backing up the Terracoin Core wallet from the File menu

Backing up by copying the wallet.dat file

If Terracoin Core is not running, you can also backup your wallet by simply copying the wallet.dat file to another location. This file is located in the TerracoinCore data folder. You were given the option to specify the location of this folder during installation, but by default the folder is in the following locations on different operating systems:

Windows

C:\Users\YourUserName\Appdata\Roaming\TerracoinCore You can access this folder directly by Windows Key + R and typing %APPDATA%\TerracoinCore

Linux

/home/YourUserName/.terracoincore You can access this folder directly by typing cd ~/.terracoincore at the terminal or ~/.terracoincore in the path bar using the Go > Enter Location... menu item in Files

macOS

/Users/YourUserName/Library/Application Support/TerracoinCore You can access this folder by typing cd ~/Library/Application Support/TerracoinCore at the terminal or ~/Library/Application Support/TerracoinCore in dialog at the Go > Go To Folder menu item in Finder Ensure Terracoin Core is not running, then simply copy the wallet.dat file from this folder to another folder in the normal way for your operating system. The example below shows copying the file to a USB stick using simple drag and drop while holding down Ctrl on a Windows system. On most operating systems, you can also right click on the file and select Copy, then select Paste in the target folder. Keep this file in a physically separate location to your computer. Be careful to copy (not move) the file!

Automatic backups

Every time you open Terracoin Core, it will automatically create a backup copy of wallet.dat in the terracoincore/backups folder. Up to 10 backups can be kept here by default, and the oldest backup will be deleted as each additional new backup is created. You can modify the number of backups kept here using the -createwalletbackups=n parameter at the command line or in terracoin.conf. Setting this value to 0 completely disables backups.

You can view the automatic backups folder by browsing to TerracoinCore folder at the location specified above for wallet.dat and opening the backups folder, or by selecting Tools > Show Automatic Backups from the menu in Terracoin Core. Since these files are not active when Terracoin Core is running, you can safely copy them at any time. They are also a handy backup if the original files in the TerracoinCore folder become corrupted due to improper shutdown of the Terracoin Core app.

Restoring backups

To restore a backup, install Terracoin Core on the target system (or stop it, if already installed) and rename the existing wallet.dat file in the TerracoinCore folder.

Then copy the backup wallet file to the TerracoinCore folder and ensure it is named wallet.dat. Now, when you start Terracoin Core again, it will load the new wallet. Do not replace wallet.dat while Terracoin Core is running, since this will result in data corruption!

Backup storage considerations

Any backup depends to some extent on the existence of software capable of reading the data at some future point in time. As such, it is good practice to store a copy of the software used to create the backup together with the backup file itself. In this case, this would be a copy of the version of Terracoin Core you used to create the backup.

The wallet.dat file itself should be encrypted using a password set from the Settings > Encrypt Wallet menu item. However, this only prevents someone with access to the file from creating transactions, not from opening the file. You could additionally store the file in another encrypted container, such as a USB stick using BitLocker in Windows, LUKS in Linux or FileVault on macOS. It is also possible to create disk images or zip files with password encryption - the choice is yours. For further reading on encrypted containers, see here.

Where you store this file is then up to you. It could be in your home, in a safe deposit box at a bank, a waterproof container, or on cloud storage such as Google Drive or iCloud. Consider where you will store any passwords needed to restore access to the wallet (in your head, on paper, in a password manager, etc.) and who may need access to the password in the future.

Finally it is important to understand that wallet.dat itself is a relatively dangerous way to store large amounts of funds - it is simply a database file storing private keys. While the convenience of storing a wallet file directly is fine for smaller holdings, it is more secure to to store large amounts of Terracoin on a single predefined address in a way that you are guaranteed access through any software supporting the protocol, rather than a specific implementation of that protocol. If you are interested in this, read more about paper wallets, where the private key can be printed directly or also encrypted using BIP38 for safe storage.

Verifying backups

There is no fixed procedure to verify your backup, but you should test restoring it at least once to make sure it works. If you have a simple copy of the file, try to restore it to your current TerracoinCore folder and start Terracoin Core to make sure it opens without any errors. If you decided to store the file in an encrypted zip file, make sure you can unzip it and that it opens correctly in Terracoin Core. In short, make sure that you (or the person you are trusting to eventually go through this process for you) can actually reverse your backup process to get access to your Terracoin, instead of relying on the fact that this process should theoretically be reversible.

Guides for advanced functions

Below are the advanced functions.

Enable the Masternodes tab

You need to enable the wallet's Masternodes tab from the Options menu.

From the wallet, select (Mac OSX) Terracoin Core => Preferences or (Windows) Settings => Optons...
Click the Wallet tab.
Check Enable coin control features and Show Masternodes Tab.
Click OK
Restart your wallet.

If your masternode.conf file has masternode entries, the Masternodes tab will now display.

Running Terracoin

Terracoin.conf Configuration File

All command-line options (except for -datadir and -conf) may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.

Commands:

terracoind -help

terracoind_-help.txt

terracoin-cli -help

terracoin-cli_-help.txt

terracoin-tx -help

terracoin-tx_-help.txt

terracoin-qt -help

terracoin-qt_-help.txt

The configuration file is a list of setting=value pairs, one per line, with optional comments starting with the '#' character.

The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, Terracoin-Qt (or terracoind) will look for a file named 'terracoin.conf' in the terracoin data directory, but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments.

 Whenever you are storing objects with a market value, security is necessary. This applies to barter systems as well as economies using currency as a medium of exchange. While banks store balances on a private ledger, cryptocurrencies store balances under unique addresses on a distributed public ledger. The cryptographic private keys to access the balance stored on each public address are therefore the object of value in this system. This section of the documentation discusses different practical methods of keeping these keys safe in wallets, while still remaining useful for day-to-day needs.

This appears as a table showing the time, type, label and amount of Terracoin for each transaction. You can also export the transaction history as a CSV file by clicking the Export button in the bottom right corner of the window.
+This option causes Terracoin Core to start automatically when the current user logs in. On most computers there is only one main user account which is logged in automatically when the computer turns on, so this option is effectively the same as starting Terracoin Core together with the operating system.
-The icons in the leftmost column indicate the status of the transaction. A tick indicates that the recommended number of confirmations has been passed, while a clock indicates that the transaction has yet to reach six confirmations.
+=====Size of database cache=====
-The transactions tab
+This option specifies the size of the database cache in memory. A higher value will result in increased performance when adding new blocks at the cost of higher memory usage. The default value is 100MB and it should not be set lower than this level.
-The status bar
+=====Number of script verification threads=====
-The status bar shows a synchronization progress bar and a row of status icons which indicate the status of your connection to the Terracoin network.
+This option sets the number of script verification threads, ranging from -4 to 16. Script verification is the process of following instructions recorded in the blockchain to ensure the transactions are valid. 0 means automatic and will allow script verification to scale to the number of cores available on your processor. Setting a positive number specifies that Terracoin Core should use that number of processor cores, while setting a negative number will leave that number of processor cores free.
-The synchronization bar
+====Wallet====
-This bar shows the synchronization status of Terracoin Core with the Terracoin network. Each time you open Terracoin Core, it will begin downloading the blocks which have been created on the blockchain in the time since you last opened the app. These blocks are downloaded from other Terracoin users and masternodes. If you have never opened the app before, this could mean several years' worth of blocks need downloading. The following statuses are possible:
+The Wallet tab of the Options dialog contains settings related to how addresses are managed in the Terracoin Core app. The first time you run Terracoin Core, it will generate a new wallet containing 1000 unique Terracoin addresses. This tab allows you to configure how these addresses are used as inputs with the Coin Control, PrivateSend and Masternode features.
-No block source available
+[[File:Options Wallet Tab.png]]
-This occurs if your internet connection is down, or if the ports required by Terracoin Core are blocked by a firewall.
+''The Wallet tab of the Terracoin Core Options dialog''
-Synchronizing with network
+=====Enable coin control features=====
-Terracoin Core is downloading blocks from the network.
+Your Terracoin Core wallet balance is actually the sum total of all addresses holding balance that are associated with your wallet. When you spend Terracoin, Terracoin Core will withdraw from as many inputs as necessary to make up the desired amount of Terracoin to be transferred. This behavior may be undesirable if you want to keep a certain balance on one address. The most common use case is the requirement to maintain 5000 Terracoin on a single address as collateral for a masternode.
-Synchronizing masternodes/masternode payments/governance objects
+Enabling this option will add a button labelled Inputs on the Send tab. This provides access to the Coin selection dialog, which can be used to lock, unlock and prioritize different addresses in your wallet. See here for a more detailed explanation of Coin Control.
-Terracoin Core is synchronizing other data with the second layer network.
+=====Show Masternodes tab=====
-Once synchronization is complete, the progress bar will disappear and a tick will appear on the right of the status bar.
+Enabling this option causes Terracoin Core to display an additional Masternodes tab to the right of the Transactions tab. This option requires you to restart the Terracoin Core app.
-The status icons
+The Masternodes tab can be used to manage interactions (start, stop, check status, etc.) with masternodes controlled by this wallet. This tab is an advanced feature not required by users that do not operate a masternode on the Terracoin network. See here for a description of the Masternodes tab.
-The lock icons indicate the status of your wallet: either locked or unlocked. You need to unlock your wallet to send funds or perform certain other actions.
+=====Enable advanced PrivateSend interface=====
-These icons indicate the quality of your connection to the Terracoin network. If you cannot connect because of network problems, you will see the icon on the left. More bars indicate more connections to your peers on the network.
+Enabling this option changes the PrivateSend mixing interface on the Overview tab of the Terracoin Core wallet to include more options, such as Try Mix and percentage completion. See here for a full explanation of how to use PrivateSend.
-These icons show the synchronization status of Terracoin Core with the network. Once synchronization is complete, the refresh icon will become a blue tick.
+=====Warn if PrivateSend is running out of keys=====
-===Terracoin Core Options===
+Enabling this option will cause Terracoin Core to display a warning when your original set of 1000 addresses is running out, which may affect PrivateSend mixing. Every time a mixing event happens, up to 9 of your addresses are used up. This means those 1000 addresses last for about 100 mixing events. When 900 of them are used, your wallet must create more addresses. It can only do this, however, if you have automatic backups enabled. Consequently, users who have backups disabled will also have PrivateSend disabled.
+=====Enable PrivateSend multi-session=====
+Normally PrivateSend mixing is completed in several consecutive rounds, each using a single masternode. Enabling this option allows multi-session, which means you can use multiple masternode servers at the same time, greatly increasing the speed of the mixing process at the cost of creating more addresses and thus requiring more frequent wallet backups. This feature is experimental as of Terracoin Core 12.1.7.
+=====Spend unconfirmed change=====
+When this option is enabled, the Terracoin Core wallet permits you to immediately spend change from previous transactions that has been transferred internally between addresses associated with the same wallet. This is possible even if the transaction has not yet been confirmed because the wallet knows it will eventually be confirmed since it created the internal transaction itself. Leaving this option enabled allows you to create new transactions even if previous transactions have not yet been confirmed.
+=====PrivateSend rounds to use=====
+Use this option to control the number of rounds of PrivateSend mixing to be carried out for your chosen balance. Each round of mixing uses a new masternode. The higher the number of rounds, the more difficult it becomes to trace the Terracoin to its original address. This is at the expense of more time required for mixing and potentially higher fees. See here for a full explanation of how to use PrivateSend.
+=====Amount of Terracoin to keep anonymized=====
+This option allows you to specify how much Terracoin should be kept on balance in a ready-to-use anonymized state, meaning it has already passed through the PrivateSend mixing process. If you do not have sufficient Terracoin available in your balance of unlocked inputs, the amount will be automatically reduced to the available balance and shown in red in the PrivateSend interface on the Overview tab.
+====Network tab====
+This tab includes options related to how your connection to the Terracoin network is made.
+[[File:Options Network Tab.png]]
+''The Network tab of the Terracoin Core Options dialog''
+=====Map port using UPnP=====
+This option causes Terracoin Core to automatically attempt to open and map the client port on your router using UPnP (Universal Plug and Play). This feature is supported by most modern home routers and will allow you to connect to the Terracoin network without making any special settings on your router.
+=====Allow incoming connections=====
+This option causes your client to accept external connections. Since Terracoin is a peer-to-peer network and Terracoin Core is considered a full client because it stores a copy of the blockchain on your device, enabling this option helps other clients synchronize the blockchain and network through your node.
+=====Connect through SOCKS5 proxy (default proxy)=====
+These options allow users on an intranet requiring a proxy to reach the broader internet to specify the address of their proxy server to relay requests to the internet. Contact your system administrator or check out the network settings in your web browser if you are unable to connect and suspect a proxy may be the source of the problem.
+=====Use separate SOCKS5 proxy to reach peers via Tor hidden services=====
+These options allow you to specify an additional proxy server designed to help you connect to peers on the Tor network. This is an advanced option for increased privacy and requires a Tor proxy on your network. For more information about Tor, see here.
+====Window tab====
+This option contains options governing behavior of the Terracoin Core app window under Microsoft Windows.
+[[File:Options Window Tab.png]]
+''The Window tab of the Terracoin Core Options dialog''
+=====Hide tray icon=====
+When this option is enabled, Terracoin Core will not display an icon in the system tray. This option cannot be selected at the same time as Minimize to the tray instead of the taskbar.
+=====Minimize to the tray instead of the taskbar=====
+When this option is enabled and the Terracoin Core window is minimized, it will no longer appear in your taskbar as a running task. Instead, Terracoin Core will keep running in the background and can be re-opened from the Terracoin icon in the system tray (the area next to your system clock). This option cannot be selected at the same time as Hide tray icon.
+=====Minimize on close=====
+When this option is enabled, clicking the X button in the top right corner of the window will cause Terracoin Core to minimize rather than close. To completely close the app, select File > Exit.
+====Display tab====
+This tab contains options relating to the appearance of the Terracoin Core app window.
+[[File:Options Display Tab.png]]
+''The Display tab of the Terracoin Core Options dialog''
+=====User interface language=====
+Select your preferred language from this drop-down menu. Changing the language requires you to restart the Terracoin Core app. Terracoin Core currently offers translations in Bulgarian, German, English, Spanish, Finnish, French, Italian, Japanese, Polish, Portuguese (Brazil), Russian, Slovenian, Swedish, Vietnamese, Simplified Chinese and Traditional Chinese.
+=====User interface theme=====
+You can use this option to select a different theme governing the appearance of the Terracoin Core window. All functionality is identical under the different themes, although the default Terracoin-light theme is most recent and most likely to work without any display artifacts.
+=====Unit to show amounts in=====
+This allows you to change the default unit of currency in Terracoin Core from TRC to mTRC, µTRC or duffs. Each unit shifts the decimal separator three places to the right. Duffs are the smallest unit into which Terracoin may be separated.
+=====Decimal digits=====
+This option allows you to select how many decimal digits will be displayed in the user interface. This does not affect internal accounting of your inputs and balance.
+=====Third party transaction URLs=====
+This option allows you to specify and external website to inspect a particular address or transaction on the blockchain. Several blockchain explorers are available for this. To use this feature, enter the URL of your favorite blockchain explorer, replacing the %s with the transaction ID. You will then be able to access this blockchain explorer directly from Terracoin Core using the context menu of any given transaction.

+''The Peers tab of the Terracoin Core Tools dialog''
+====Wallet Repair====
+The Wallet Repair tab offers a range of startup commands to restore a wallet to a functional state. Selecting any of these commands will restart Terracoin Core with the specified command-line option.

+===Salvage wallet===
+Salvage wallet assumes wallet.dat is corrupted and cannot be read. It makes a copy of wallet.dat to wallet.<date>.bak and scans it to attempt to recover any private keys. Check your debug.log file after running salvage wallet and look for lines beginning with "Salvage" for more information on operations completed.
+===Rescan blockchain files===
+Rescans the already downloaded blockchain for any transactions affecting accounts contained in the wallet. This may be necessary if you replace your wallet.dat file with a different wallet or a backup - the wallet logic will not know about these transactions, so a rescan is necessary to determine balances.
+===Recover transactions===
+The recover transactions commands can be used to remove unconfirmed transactions from the memory pool. Your wallet will restart and rescan the blockchain, recovering existing transactions and removing unconfirmed transactions. Transactions may become stuck in an unconfirmed state if there is a conflict in protocol versions on the network during PrivateSend mixing, for example, or if a transaction is sent with insufficient fees when blocks are full.
+===Upgrade wallet format===
+This command is available for very old wallets where an upgrade to the wallet version is required in addition to an update to the wallet software. You can view your current wallet version by running the getinfo command in the console.
+===Rebuild index===
+Discards the current blockchain and chainstate indexes (the database of unspent transaction outputs) and rebuilds it from existing block files. This can be useful to recover missing or stuck balances.
+==How to send and receive Terracoin==
+==Transactions==
+Your Terracoin Core Wallet is associated with a number of unique addresses that can be used to send and receive TRC. Each address holds its own balance, and the sum of all your balances is what appears on the Overview tab. When you send Terracoin, your wallet will automatically transfer funds from as many of your addresses as necessary to the destination address, which is controlled by another Terracoin user and associated with their wallet. You can control which addresses you use using the Coin Control feature.
+When you confirm a transaction, Terracoin Core will enter the transaction in a block, which will then be added to the blockchain for other clients to confirm. A transaction is generally considered confirmed once six blocks have been added after the block containing your transaction, although masternode and mining payments are only released after 101 blocks. Note that a different process is used for InstantSend and PrivateSend transactions.
+Terracoin addresses are 34 characters long and begin with a 1.
+===Sending Terracoin===
+You can use Terracoin Core to send Terracoin from your balance to another user. The receiving user will provide you with a Terracoin address to which you should send the funds. Click the Send tab in the tab bar and enter the destination address in the Pay To field.
+[[File:Send Tab No Control.png]]
+''The Terracoin Core Send tab''
+You can also use the three icons to the right of the Pay To field to select a previously used address, paste an address from the clipboard, or clear the current address. If this is a new address, you can enter a name for the address in the Label field to help identify it again later. Finally, enter the amount of Terracoin you want to transfer in the Amount field.
+The other options relate to fees and PrivateSend/InstantSend. You can choose if you want to pay the network fee in addition to the amount sent, or subtract it from the amount sent. You can also increase your fee to encourage nodes on the network to prioritize your transaction. Choosing InstantSend has a similar effect, but actually relies on a different mechanism in the second layer network to speed up the transaction time. You can read more about InstantSend here. Choosing PrivateSend will send Terracoin from an address that has previously been mixed. You can find out more about PrivateSend and mixing here.
+Let’s try an example. Say you have decided to donation 5 TRC to the Terracoin Foundation.
+[[File:Send Tab Filled Out.png]]
+''The Send tab filled out for a transaction''
+Once you have entered the destination address and the amount, click the Send button. If you have encrypted your wallet, you will now be required to enter your password to unlock the wallet.
+[[File:Send Tab Password.png]]
+''Entering the password to unlock the wallet''
+Finally, you are given one final confirmation and chance to cancel your send transaction before Terracoin Core processes the transaction on the blockchain.
+[[File:Send Tab Final Confirmation.png]]
+''Final confirmation window''
+If you respond with Yes, your transaction will be processed. Your operating system may display a notification, and the transaction will appear on the Transactions tab, where you can monitor its progress.
+[[File:Send Tab Sent.png]]
+''The Windows 10 sent transaction confirmation notification''
+Note that the amount of the transaction increased by .00007460 Terracoin. This is the transaction fee. In the next section, we will see what this procedure looks like from the receiving side.
+===Receiving Terracoin===
+To receive Terracoin, you must first create a receiving address to give to the sending party. To do this, click File > Receiving addresses. The Receiving addresses window appears.
+[[File:Receive Addresses.png]]
+''The Receiving addresses window''
+Either copy an existing address by clicking on the address and then the Copy button, or create a new address by clicking the New button. You can also edit an existing address by right clicking and selecting Edit address from the context menu. Give this address to the person who will send you Terracoin. Your wallet does not need to be open to receive funds, but if it is, you can watch the transaction arrive in real time. This is because your wallet constantly watches for new blocks on the blockchain when it is open, and will recognize a new transaction involving your receiving address when it occurs.
+[[File:Incoming Transaction.png]]
+''The Windows 10 received transaction confirmation notification''
+Once you have been paid, you can see the balance both on the Overview tab and on the Transactions tab.

+''The received transaction''
+==How to use PrivateSend==
+Below describes how to use the Terracoin client to run PrivateSend and anonymize your Terracoin. PrivateSend, rebranded from DarkSend in May 2016, is a trustless method of running a sequence of transactions such that an external observer is unable to determine the source of funding when a PrivateSend transaction is created. This gives your Terracoin the same anonymous properties as cash withdrawn from an ATM, for example. By using this software, you agree not to use it for illegal purposes and that you are solely responsible for any lost Terracoin.
 ===Introduction to PrivateSend===
+With the introduction of Release Candidate 4 (RC4) of the Darkcoin client, it became possible to store pre-mixed, denominated Terracoin in the user’s wallet, to be used instantly at any time the user desires. The mixing and denomination process is seamless, automatic, and requires no intervention on the part of the user. The current implementation of PrivateSend in the Terracoin Core wallet allows any amount of Terracoin to be mixed for later use in PrivateSend transactions.
+Here's how it works:
+*Every 10 blocks, user clients network-wide will send any unmixed, traceable Terracoin in their possession through an anonymization phase. In this phase, masternodes are used in chained succession to mix the coins they receive from the network and break them down into homogenous denominations.
+*After being processed by a minimum of 2 masternodes, the coins are either sent to the next masternode in the chain or back to the user’s wallet at randomly generated change addresses.
+*Depending on the desired depth of security and privacy, users may select between 2 and 8 “hops” to successive masternodes before their coins are sent back to the client. Hops are made every 10 blocks, so anonymization at a depth of 2 hops will take 2*2.5=5.0 minutes, 3 hops 3*2.5=7.5 minutes, and so on. The desired mixing depth can be selected in the client GUI.
+*At the end of the anonymization phase, the user’s coins are returned to their client at randomly generated change addresses. When the user wishes to make a transaction, the client forwards the intended amount from these anonymous change addresses directly to the intended receiver’s address. There is no direct involvement of of masternodes in the final person-to-person transaction.
+*Proof of payment will work as it always has: a user can see the send transaction with the receiver’s address in their own wallet, and the blockchain will show that the receiver’s address received an input in the corresponding amount.
 ===Setting default PrivateSend options===
+. Open your Terracoin Core wallet, go to Settings and select Options. Go to the Wallet tab.
+[[File:PrivateSend Options Wallet.png]]
+''Terracoin Options Wallet PrivateSend Advanced''
+. Next to PrivateSend rounds to use, enter a value between 1-8.
+Each round of PrivateSend performs one denominated fund mixing transaction. Higher numbers of rounds increase your overall level of anonymity while decreasing the chance of detection via node collusion. 8 is the highest number of rounds currently available.
+NOTE: each round of PrivateSend includes a masternode fee of 0.0125 Terracoin.
+. Enter a target value for Amount of Terracoin to keep anonymized.
+This value provides a lower boundary on the final amount of funds to be anonymized. Depending on how the client splits your wallet balance, you may end up with denominated inputs whose sum total is greater than the target amount. In this case the client will use all existing denominated inputs in the PrivateSend process. The final anonymized amount may be higher than your target, but should be close.
+. Click OK to save settings.
+. PrivateSend is disabled by default when you open the wallet. It will only start after you set the number of rounds and number of Terracoin to mix under settings and click Start Mixing on the Overview tab of your wallet.
 ===Initiating the PrivateSend process===
+The PrivateSend process is initiated by clicking the Start Mixing button on the Overview tab of the Terracoin Core wallet. Mixing is possible once the following conditions have been met:
+The wallet contains sufficient non-anonymized funds to create the minimum required denominated values
+The user has not disabled PrivateSend in the Options dialog
+The target value for anonymized Funds in the Options dialog is greater than zero
+If your wallet is encrypted (highly recommended), you will be asked to enter your wallet passphrase. Enable the Only for mixing via PrivateSend checkbox to unlock the wallet for mixing only.
+[[File:PrivateSend Password.png]]
+''Entering a password for PrivateSend mixing only''
+This will unlock your wallet, and the PrivateSend mixing process will begin. The wallet will remain unlocked until PrivateSend mixing is complete, at which point it will be locked automatically.
+[[File:PrivateSend Progress.png]]
+''PrivateSend interface after clicking the Start Mixing button. Note the Status is Enabled.''
+PrivateSend will begin creating transactions and your PrivateSend balance will gradually increase. This process can take some time, so be patient. You can monitor the process in more detail as described here.
+Any of the following actions will interrupt the mixing process. Because the transactions are atomic (they either take place completely, or do not take place at all), it should be possible to safely interrupt PrivateSend mixing at any time.
+Clicking the Stop Mixing button on the Overview tab
+Closing the client before PrivateSend mixing is completed
+Sending PrivateSend funds from the wallet before PrivateSend rounds are completed
+Disabling PrivateSend before the process is complete
 ===Monitoring PrivateSend progress===
+If you want to monitor PrivateSend in more detail, you need to enable some advanced features of the wallet. Go to Settings, select Options and go to the Wallet tab. Check the boxes next to the Enable coin control features and Enable advanced PrivateSend interface options.
+[[File:PrivateSend Options Interface.png]]
+''Enabling advanced options for PrivateSend in the Terracoin Core wallet settings''
+This will allow you to monitor progress and see which individual operations PrivateSend is carrying out in the background.
+[[File:PrivateSend Progress.png]]
+''Monitoring PrivateSend progress''
+This will allow you to monitor progress and see which individual operations PrivateSend is carrying out in the background.
+Since PrivateSend mixing creates a lot of new address keys to send and receive the anonymized denominations, you may receive a warning when the number of remaining keys runs low. This is nothing to be worried about, since the wallet will simply create more keys as necessary. However, these keys will not exist in any previous backups of your wallet. For this reason, it is important to backup your wallet again after mixing is complete.
+You can also monitor PrivateSend progress by viewing the transactions created by the mixing process on the Transactions tab.
+[[File:PrivateSend Transactions.png]]
+''Transactions created by PrivateSend on the Transactions tab''
+You can also use the coin control feature to view which addresses hold mixed denominations ready to be used for PrivateSend transactions. Go to the Send tab of your wallet and click Inputs to view the possible input addresses for your transactions. You can see how each address holds given denominations of mixed Terracoin, and how many rounds of mixing have been completed. This is to ensure that an efficient combination of addresses can be used as inputs in PrivateSend transactions without too much change, since amount in a PrivateSend transaction must be rounded up to completely spend all inputs. The current minimum balance for an input used in a PrivateSend transaction is 0.01000010 Terracoin.
+[[File:PrivateSend Denominations.png]]
+''Coin Selection dialog showing addresses holding PrivateSend mixed balances in different denominations''
 ===Sending payments with PrivateSend===
+You can only use PrivateSend for payments once you have mixed enough Terracoin to make up the amount you are trying to send. Because the mixing process takes time, it must be done in advance before you create the send transaction. A PrivateSend transaction is effectively the same as any other transaction on the blockchain, but it draws only from input addresses where the denomination has previously been mixed to ensure anonymity of funds. Because several input addresses are usually required to make up the amount you are trying to send, a PrivateSend transaction will usually take up more space (in kilobytes) on the blockchain, and therefore will be charged a slightly higher fee. To send a payment using PrivateSend, go to the Send tab of the Terracoin Core wallet and enable the PrivateSend option. The balance displayed will change to show your PrivateSend balance instead of the total balance. You can then enter the Pay To address, Label, Amount and click Send as usual. Your payment will be rounded up to completely spend the lowest possible denomination of mixed balance available (currently to the nearest 0.01 TRC). You will be prompted to enter your password and receive a detailed breakdown of the fee structure for PrivateSend before sending.

+==How to safely back up your wallet==
+===Introduction===
+This documentation describes how to safely back up your wallet file for safe storage in case your computer or laptop is damaged or lost. Terracoin Core stores all data necessary to control your Terracoin addresses in a single file called wallet.dat. This wallet is in the Berkeley DB format and stores the pairs of private/public cryptographic keys used to manage your balances on the Terracoin blockchain. Terracoin Core makes most of these operations transparent and even generates automatic backups of your wallet file in case it is corrupted, but the user is responsible for ensuring that these backups are stored in a safe place. If you lose access to these key pairs, you will permanently lose access to your Terracoin.
+It is important to consider that if you have not encrypted your wallet using the Settings > Encrypt Wallet menu item, anyone with access to the backed up wallet.dat file will immediately have full access to your Terracoin. If you do choose to encrypt your wallet, do not store the password in the same place as the wallet.dat file, particularly if you are saving the backup to the cloud.
+===Backing up your wallet===
+====Backing up from Terracoin Core====
+Firstly, never copy your wallet.dat file while Terracoin Core is open. Always use the File > Backup Wallet menu if the wallet is open. When you select this menu item, a dialog box will appear to specify where the file should be saved. Enter a name for the file, select a location and click Save. The example below shows saving the file to a USB stick. Keep this file in a physically separate location to your computer.
+[[File:Backup Wallet.png]]
+''Backing up the Terracoin Core wallet from the File menu''
+====Backing up by copying the wallet.dat file====
+If Terracoin Core is not running, you can also backup your wallet by simply copying the wallet.dat file to another location. This file is located in the TerracoinCore data folder. You were given the option to specify the location of this folder during installation, but by default the folder is in the following locations on different operating systems:
+*Windows
+C:\Users\YourUserName\Appdata\Roaming\TerracoinCore
+You can access this folder directly by Windows Key + R and typing %APPDATA%\TerracoinCore
+*Linux
+/home/YourUserName/.terracoincore
+You can access this folder directly by typing cd ~/.terracoincore at the terminal or ~/.terracoincore in the path bar using the Go > Enter Location... menu item in Files
+*macOS
+/Users/YourUserName/Library/Application Support/TerracoinCore
+You can access this folder by typing cd ~/Library/Application Support/TerracoinCore at the terminal or ~/Library/Application Support/TerracoinCore in dialog at the Go > Go To Folder menu item in Finder
+Ensure Terracoin Core is not running, then simply copy the wallet.dat file from this folder to another folder in the normal way for your operating system. The example below shows copying the file to a USB stick using simple drag and drop while holding down Ctrl on a Windows system. On most operating systems, you can also right click on the file and select Copy, then select Paste in the target folder. Keep this file in a physically separate location to your computer. Be careful to copy (not move) the file!
+===Automatic backups===
+Every time you open Terracoin Core, it will automatically create a backup copy of wallet.dat in the terracoincore/backups folder. Up to 10 backups can be kept here by default, and the oldest backup will be deleted as each additional new backup is created. You can modify the number of backups kept here using the -createwalletbackups=n parameter at the command line or in terracoin.conf. Setting this value to 0 completely disables backups.
+You can view the automatic backups folder by browsing to TerracoinCore folder at the location specified above for wallet.dat and opening the backups folder, or by selecting Tools > Show Automatic Backups from the menu in Terracoin Core. Since these files are not active when Terracoin Core is running, you can safely copy them at any time. They are also a handy backup if the original files in the TerracoinCore folder become corrupted due to improper shutdown of the Terracoin Core app.
+===Restoring backups===
+To restore a backup, install Terracoin Core on the target system (or stop it, if already installed) and rename the existing wallet.dat file in the TerracoinCore folder.
+Then copy the backup wallet file to the TerracoinCore folder and ensure it is named wallet.dat. Now, when you start Terracoin Core again, it will load the new wallet. Do not replace wallet.dat while Terracoin Core is running, since this will result in data corruption!
+===Backup storage considerations===
+Any backup depends to some extent on the existence of software capable of reading the data at some future point in time. As such, it is good practice to store a copy of the software used to create the backup together with the backup file itself. In this case, this would be a copy of the version of Terracoin Core you used to create the backup.
+The wallet.dat file itself should be encrypted using a password set from the Settings > Encrypt Wallet menu item. However, this only prevents someone with access to the file from creating transactions, not from opening the file. You could additionally store the file in another encrypted container, such as a USB stick using BitLocker in Windows, LUKS in Linux or FileVault on macOS. It is also possible to create disk images or zip files with password encryption - the choice is yours. For further reading on encrypted containers, see here.
+Where you store this file is then up to you. It could be in your home, in a safe deposit box at a bank, a waterproof container, or on cloud storage such as Google Drive or iCloud. Consider where you will store any passwords needed to restore access to the wallet (in your head, on paper, in a password manager, etc.) and who may need access to the password in the future.
+Finally it is important to understand that wallet.dat itself is a relatively dangerous way to store large amounts of funds - it is simply a database file storing private keys. While the convenience of storing a wallet file directly is fine for smaller holdings, it is more secure to to store large amounts of Terracoin on a single predefined address in a way that you are guaranteed access through any software supporting the protocol, rather than a specific implementation of that protocol. If you are interested in this, read more about paper wallets, where the private key can be printed directly or also encrypted using BIP38 for safe storage.
+===Verifying backups===
+There is no fixed procedure to verify your backup, but you should test restoring it at least once to make sure it works. If you have a simple copy of the file, try to restore it to your current TerracoinCore folder and start Terracoin Core to make sure it opens without any errors. If you decided to store the file in an encrypted zip file, make sure you can unzip it and that it opens correctly in Terracoin Core. In short, make sure that you (or the person you are trusting to eventually go through this process for you) can actually reverse your backup process to get access to your Terracoin, instead of relying on the fact that this process should theoretically be reversible.
+==Guides for advanced functions==
+Below are the advanced functions.

 ===Running Terracoin===
+====Terracoin.conf Configuration File====
+All command-line options (except for -datadir and -conf) may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.
+Commands:
+terracoind -help
+terracoind_-help.txt
+terracoin-cli -help
+terracoin-cli_-help.txt
+terracoin-tx -help
+terracoin-tx_-help.txt
+terracoin-qt -help
+terracoin-qt_-help.txt
+The configuration file is a list of setting=value pairs, one per line, with optional comments starting with the '#' character.
+The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, Terracoin-Qt (or terracoind) will look for a file named 'terracoin.conf' in the terracoin data directory, but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments.
