II. Dynamic Staking Reward Algorithm

The staking reward distribution employs a Dynamic APY Adjustment Model based on protocol revenue and token supply-demand balance:

1. Mathematical Model:

   • Reward Formula:

     RewardPerBlock=ProtocolRevenue×0.5TotalStaked×InflationRateBlocksPerYearRewardPerBlock=TotalStakedProtocolRevenue×0.5​×BlocksPerYearInflationRate​

   • Inflation Adjustment: If LSP price falls below a target threshold (e.g., $1.0), the DAO can vote to reduce the inflation cap.

2. Code Implementation:

   solidity复制

   // Dynamic Reward Distribution Contract
   contract DynamicRewards {
       uint256 public inflationRate;  // Current annual inflation rate (initial 2%)
       uint256 public targetPrice;    // LSP target price (e.g., $1.0)
       uint256 public blocksPerYear = 2102400; // Arbitrum blocks/year (~1.3s/block)
   
       // Calculate per-block rewards
       function calculateReward(uint256 totalStaked, uint256 protocolRevenue) public view returns (uint256) {
           uint256 revenueShare = protocolRevenue * 50 / 100; // 50% revenue for rewards
           uint256 annualReward = revenueShare + (totalStaked * inflationRate) / 100;
           return annualReward / blocksPerYear;
       }
   
       // DAO adjusts inflation rate (requires governance vote)
       function adjustInflation(uint256 newRate) external onlyDAO {
           require(newRate <= 2, "Max inflation 2%");
           inflationRate = newRate;
       }
   }
