What is VF Cash?

VF Cash is a Cryptocurrency project that started on the 23rd of April 2019. It has no Proof-of-Work (POW) but instead features the world’s first Proof-of-Key (POK) algorithm, consisting of a finders-keepers distribution system similar to mining, and a transaction rate limit per address / public key of three seconds for the confirmation period. This prevents the sender of the transaction from making any further transactions during this period. VF Cash is a minimal implementation unordered chain, commonly referred to as a directed acyclic graph (DAG), and the networking uses UDP. The Digital Signature algorithm uses secp256r1.

Divisible to three decimal places, VF Cash is written in C, compiled with GCC, 256-bit key length, Transactions are 76.16% smaller than an average Bitcoin-Core transaction.

Transactions are free as there are no charges for making a transaction on the network. However, transactions do create inflation of the currency which is partly paid back to the node operators as rewards.

In the spirit of Bitcoin, VF Cash is a decentralised peer-to-peer digital cash protocol and not a company. An initial Core Working Group has been established to provide guidance and direction to VC Cash in the early stage of its existence. Once the network matures, all operational matters will be turned over to the community, via the formation of a decentralised autonomous organisation (DAO) or other legal means.

Frequently Asked Questions (FAQ)

  • git clone https://github.com/vfcash/VFC-Core && cd VFC-Core
  • chmod 0777 compile.sh
  • sudo ./compile.sh
  • vfc cdn_resync
  • Install(s) to /usr/bin/vfc
  • Ensure you have the UDP Port 8787 forwarded.
  • Run "vfc mine" and earn some VFC to register your node on the network.
  • Make sure you run compile.sh as root, for example: sudo ./compile.sh
  • If you are behind a router, make sure you have UDP port 8787 forwarded to the correct local IP address on your network.
  • If you are in China, you will find that you may have your internet connection dropped periodically due to the use of UDP.
  • Please ensure you have an IPv4 address.
  • You do not need to run a local node to mine and claim VFC rewards to your rewards address. However, it is highly suggested you run a node so that you are not limited by the restrictions on the REST API.
  • If you are mining offline with Linux, you can claim your mined VFC rewards by entering "vfc claim" into the console, or to see your unclaimed addresses use "vfc unclaimed".
  • To launch the miner enter "vfc mine" into the console.
  • You can claim your mined VFC rewards by entering "vfc claim" into the console, or to see your unclaimed addresses use "vfc unclaimed".
  • Your data directory is located at ~/.vfc/. You can change this by setting the Environment Variable VFCDIR to a custom directory path.
  • Your reward address private key is located in ~/.vfc/private.key. This is all you need to perform a backup.
  • Your minted private keys are located in ~/.vfc/minted.priv
  • Once you are up and running, you just need to enter the command "vfc help" into the console.
