Running Vertcoin Core
The first time you run Vertcoin Core, it wil ask where you would like to store its data. You may chose to store data in the default directory or you may chose your own. After selecting a directory and clicking next, Vertcoin Core will attempt to connect to other Vertcoin Core nodes and download a complete copy of the blockchain.
!!!caution “Note” The Vertcoin Core Wallet requires at least 4 GB of space on your computer to store the blockchain. Downloading the entire chain for the for time may take a while.
As the blockchain downloads, you’ll see progress displayed as well as the latest block synced. Every time Vertcoin Core is launced, your local copy of the blockchain will need to be synced to the current block.
Backing Up Your Wallet
It is important to understand that vertcoin wallets contain only keys. The “coins” are recorded in the blockchain on the vertcoin network. Users control the coins on the network by signing transactions with the keys in their wallets. In a sense, a vertcoin wallet is a keychain.[1]
Vertcoin Core creates a nondeterministic wallet,where each key is independently generated from a random number. The keys are not related to each other. This type of wallet is also known as a JBOK wallet from the phrase “Just a Bunch Of Keys.”[1]
It is crucial that you back up your wallet.dat file found in your Vertcoin data directory.
Sending & Recieving Vertcoin
Once your Vertcoin Core client has finished syncing to the blockchain you are ready to send and recieve Vertcoin.
To recieve Vertcoin press the Receive button
* Fill out optional fields
* Click Request payment
To send Vertcoin press the Send button
* Enter recieve address you want you want to pay Vertcoin
* Enter the amount of VTC to send
* Attach an optional label
Addresses
In the payment portion of a vertcoin transaction, the recipient’s public key is represented by its digital fingerprint, called a vertcoin address, which is used in the same way as the beneficiary name on a check (i.e., “Pay to the order of”). In most cases, a vertcoin address is generated from and corresponds to a public key.[1]
In vertcoin, we use public key cryptography to create a key pair that controls access to vertcoin. The key pair consists of a private key and—derived from it—a unique public key. The public key is used to receive funds, and the private key is used to sign transactions to spend the funds.[2]
Coin Controls
When you send vertcoin to someone else, the vertcoin client chooses automatically picks which addresses you own that hold VTC balance will send coins. Coin control allows control over what coins you send, and which of your addresses sends VTC. More specifically, which of your unspent outputs will be the sending inputs.[3]
