Delegated Staking

This method is now deprecated and not supported. Refer Staking App (https://staking.videocoin.network) for more details
VID Token holders can actively participate in securing the VideoCoin network by delegating portion of their tokens to transcode workers. The transcoding work is distributed to workers in proportion to the total stake on each worker. The total stake of a worker includes the self stake and delegated stake by one or more delegators. The delegated stake can be withdrawn. However the VID tokens are transferred to the holder's account after expiry of the unbonding time which is currently set at 21 days.
Delegators will be rewarded by distributing portion of the rewards earned by the worker. Please refer the document  reward distribution for the details.

Delegation and withdraw can be performed through a command line tool called staker that is currently supported on Linux platforms. Follow the below steps:
Download the command line tool staker (Contact VideoCoin support for the download link)
Setup a configuration file in the format of Ethereum key store file that contains private key and public key (password protected)
Run the delegate or withdraw commands as shown in the following sections.
Setup
The staker tool needs to communicate with the Ethereum mainnet to access VID tokens.
You can use a free or paid subscription from Infura to access Ethereum through  web interace. Please visit the Infura website (https://infura.io/product) and obtain a your ID and make it available to the staker tool using an environment variable as follows.
export ETH_RPC_URL=https://mainnet.infura.io/v3/<Your Project ID>
Prepare an Ethereum key file that contains your private key in encrypted form. Following is a sample key file
{
   "address":"958636174482ee1f5e42276c72541dd3f7e5b185",

Delegation Process
Currently the delegation is a two step process. First step is to move the erc-20 VID tokens form Ethereum main net to VideoCoin network. The second step is to stake native VID on the worker that you choose.
 
Use the following command to transfer VID tokens from Ethereum main net to VideoCoin network:
$ videocoin fund amount -k <key file> -s <password>
Use the following command to delegate VID to a worker:
$ staker delegate add worker.PuK amount -k <key file> -s <password>ParameDescription
Parameter
Description
worker.PuK
Address of worker for which delegation is requested
amount
Amount of VID  to be delegated
If the worker is not registered with the VideoCoin, the command fails. VideoCoin explorer can be used to obtain the list of workers registered with the VideoCoin Network
Withdraw Process
Use the following command to withdraw stake from a worker:
$ staker delegate withdraw worker.PuK -k <key file> -s <password>
Parameter
Description
worker.PuK
Address of worker from which delegator is withdrawing stake
The withdrawn stake is deposited to delegators account only after expiry of unbonding period
Use the following command to complete pending unbonding requests that are initialted in the previous step:
$ staker withdraw complete -k <key file> -s <password>
Use the following command to transfer VID from VideoCoin network ERC-20 VID tokens on Ethereum main net:
$ staker withdraw <amount> -k <key file> -s <password>
Parameter
Description
amount
Amount of VID  to be transferred from VideoCoin network to erc-20 on  Ethereum Mainnet
