VF Cash is a mineable cryptocurrency built from the ground up featuring cutting edge cryptography and the world's first Proof-of-Key algorithm. Lightweight, secure, and fast, you can use VF Cash to safely and effortlessly send any amount of value, whether it is a micropayment for an IoT device or vast sums transferred between institutions. Transactions are instant and there are no transaction fees.
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.
How Can I Receive Rewards?
You can contribute to the VF Cash network and receive VFC as rewards by becoming a miner, node operator, or both. VF Cash supports both online and offline mining. Miners hunt for private keys and are rewarded with the random VFC balances stored within. Node operators play a crucial role in verifying transactions on the network and directly influence the network’s difficulty level throughout the day by selecting a difficulty level which is averaged together with the levels submitted by other nodes.
To mine VFC, please compile our Portable Standalone Miner here. Learn how to set up a full node on Linux here.
git clone https://github.com/vfcash/VFC-Core && cd VFC-Core
chmod 0777 compile.sh
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. Otherwise use a VPN with IPv4 Port Forwarding such as airvpn.org, a good option for users in China who get disconnected a lot due to the UDP protocol. AirVPN can force all traffic to arrive via a TCP tunnel.
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 anyway, as nodes receive additional reward payments. Node operators can also directly influence the overall network difficulty throughout the day by selecting a difficulty level which is averaged together with the difficulty levels submitted by other nodes.
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.
Yes, you can! Please use the Portable Standalone Miner here.
