Overview
This is a contest to evaluate the entirety of the GoGoPool Protocol, a decentralized liquid staking protocol on Avalanche. Our mission is to be the easiest way to stake AVAX. GoGoPool allows users with hardware and 1000 AVAX to create a validator node in conjunction with funds deposited by liquid staking users.
A detailed description of the protocol can be found in Notion, but here's a short summary
The protocol consists of two user groups, Liquid Stakers and Node Operators.
Liquid Stakers
Liquid Stakers deposit AVAX into an ERC4626 (TokenggAVAX) and receive ggAVAX in return that increases in value compared to AVAX as rewards from staking are deposited.
Node Operators
Node Operators join the protocol by creating Minipools where they deposit AVAX, request some amount of Liquid Staker AVAX and put up 10% of the requested amount in GGP. GGP, our protocol token, is how we ensure rewards for Liquid Stakers if the Node Operator does not maintain sufficient uptime for Avalanche rewards.
Staking rewards are split between Node Operators and Liquid Stakers with Node Operators getting 50% + a variable commission fee, and Liquid Stakers receiving the remainder.
Node Operators are additionally incentivized with GGP Rewards. GGP is our protocol token that inflates 5% per year. Inflated tokens are distributed between Node Operators, Protocol DAO members and Multisig Oracle maintainers. Node Operators receive GGP proportionally to how much GGP they have staked.
