Differences between SV, SSV and OV on StaFi Protocol.

The rETH is now live on Mainnet, stalkers can now enjoy the staking derivative of ETH2 pending the time the incentive campaign will be launched.

StaFi's rETH (reward-Ethereum) is Ethereum 2.0 staking liquidity solution, it is created to solve the problem of delegation and liquidity problem of staked ether. The main reason for the creation of rETH is to enable stakers have the freedom to stake without having to worry about the liquidity of their staked assets as rETH which can be traded will be provided by the protocol.

32 ETH is required by the ETH2.0 ecosystem as minimum staking amount, but with rETH the minimum staking amount will be lowered to 0.01 ETH. The rETH tokens which will be provided to stakers after staking can be traded on decentralized exchanges like Uniswap almost immediately.

For proper information about rETH solution, check here:

StaFi protocol needs a large number of ETH 2.0 validators to run the ETH 2.0 nodes with the allocated stakers’ funds in the rETH solution as an Original Validator (OV).

There are three types of validators on StaFi protocol, it is possible for those interacting with the
StaFi chain for the first time to misunderstand the description of the validators. They are:
1) StaFi Validator (SV)
2) StaFi Special Validator (SSV)
3) Original Validator (OV)

I will be explaining what their differences using Name, Base blockchain, Responsibility, Numbers, Rewards, Staking Requirement, Estimated Annualized Yield, Hardware Requirement, How to join and Participation availability.

Name: StaFi validator

Base blockchain: StaFi chain

Responsibility: provide security to StaFi chain

Numbers: 1000

Rewards: staking rewards of StaFi chain

Staking Requirement: FIS self Bond > 1

Estimated Annualized Yield: 19%

Hardware Requirement:
Ubuntu 18.04
CPU: 2 cores, Intel Core
Memory: 8G
Hard disk: 200G

How to join: Establish and operate validate nodes on StaFi chain

Participation availability: Yes

Name: StaFi Special Validator

Base blockchain: StaFi Chain

Responsibility: Provide security to StaFi staking contracts

Numbers: unlimited

Rewards: staking contract liquidity fee sharing

Staking Requirement:
FIS Self Bond = n% of staked asset

Estimated Annualized Yield:
% of liquidity fee

Hardware Requirement:
system: Ubuntu 18.04
CPU: 2 cores, Intel Core
Memory: 8G
Hard disk: 200G

How to join: Provide validation service for staking contract

Participation availability: No

Name: Original validator

Base blockchain: PoS chains like, Ethereum, polkadot, etc

Responsibility: Provide security to designated PoS chains

Numbers: depends

Rewards: staking rewards of designated PoS chains

Staking Requirement: depends

Estimated Annualized Yield:

Hardware Requirement: depends

How to join: Establish and operate validator nodes on designated PoS chains

Participation availability: yes (rETH and rFIS)

In rETH, Original Validators specifically refer to the Ethereum 2.0 validators who have joined the StaFi rETH OV program and run nodes for the funds in rETH Staking Pool.

The StaFi rETH Original Validator Recruitment Campaign is still on going, check here for a detailed description of how to join:
