An example paper printable bitcoin wallet consisting of one bitcoin address for receiving and the corresponding private key for spending. A cryptocurrency wallet stores the public and private keys which can be used to receive or spend the cryptocurrency. A wallet can contain multiple public and private key pairs. Every piece of cryptocurrency has a private key. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. Just like with a bank, the user needs to trust the provider to keep the cryptocurrency safe. Trust was misplaced in the case of the Mt.

Gox exchange, which ‘lost’ most of their clients’ bitcoins. A mnemonic sentence from which the root key can be generated, from which all the private keys can be recreated. Preferably these words could be remembered or written down and stored on other physical locations. When the private keys and the backup are lost then that cryptocurrency is lost forever.

When using a webwallet, the private keys are managed by the provider. When owning cryptocurrency, those trusted with managing the private keys should be carefully selected. When using a web wallet the private keys are managed by a trusted third party. In that case a keylogger is not enough for a hacker to steal the credentials and get access to the wallet. In order to initiate or verify a transaction, the cryptocurrency wallet connects to a client or node on the network to process the request. There are several types of clients like: full clients, headers-only clients, thin clients and mining clients.

What is Cryptography? – Definition from Techopedia

Some of them can process transactions and some of them also have their own wallet functionality. An actual bitcoin transaction from a web based cryptocurrency exchange to a hardware wallet. When the user of a hardware wallet requests a payment, the wallet’s API creates the transaction. Then the wallet’s hardware signs the transaction and provides a public key, which is sent to the network by the API. That way, the signing keys never leave the hardware wallet. If a hardware wallet uses a mnemonic sentence for backup, then the users should not electronically store the mnemonic sentence, but write it down and store in a separate physical location.

Storing the backup electronically lowers the security level to a software wallet level. With a watch only wallet someone can keep track of all transactions. Thus the private key can be kept safe in another location. Terms also used in the context of cryptocurrency wallets are hot and cold wallets. Hot wallets are connected to the internet while cold wallets are not. With a hot wallet cryptocurrency can be spent at any time.

A cold wallet has to be ‘connected’ to the internet first. As long as something is connected to the internet, it is vulnerable to an attack. Deep cold storage is the process of storing cryptocurrencies in cold wallets that were never connected to the Internet or any kind of network. Additionally the private keys associated with this system are generated offline. This section needs additional citations for verification. With a deterministic wallet a single key can be used to generate an entire tree of key pairs. This single key serves as the “root” of the tree.

The generated mnemonic sentence or word seed is simply a more human-readable way of expressing the key used as the root, as it can be algorithmically converted into the root private key. Those words, in that order, will always generate the exact same root key. A mnemonic sentence is considered secure. It creates a 512-bit seed from any given mnemonic. The set of possible wallets is 2512. Every passphrase leads to a valid wallet.

If the wallet was not previously used it will be empty. In a non-deterministic wallet, each key is randomly generated on its own accord, and they are not seeded from a common key. Therefore, any backups of the wallet must store each and every single private key used as an address, as well as a buffer of 100 or so future keys that may have already been given out as addresses but not received payments yet.

I think most of the info is in the question but here’s a little more detail on what I’m trying to achieve. I control VLC via my Android phone and the VLC Remote app. It works just fine, but I’d prefer to run a different service on port 8080.

I’m running VLC on Windows 7 64-bit. To be clear, I have VLC running on my PC, displaying the content on the PC, but the control is handled by the smartphone. You can start it using certain parameters to modify the port number, as dictated by the VLC documentation. Thanks for the suggestion but this doesn’t seem to do wat I need. I can see in TCPView that port 8001 is open but I can’t raise it through the remote control app. This also doesn’t show anything on the PC monitor I’d really appreciate if you’ve any other ideas? Image is shown on PC and control is handled by the phone.
