Here's a complete and correct markdown document of the previous response:
Let P_i be the performance score of validator i, where 0 ≤ P_i ≤ 100.
Let n be the total number of validators.
The average performance score P̄ on day t is calculated as:
P̄_t = (∑_{i=1}^n P_i) / n
Let S_t be the token supply on day t.
The daily supply adjustment factor α_t is defined as:
α_t = {
1.001 if P̄_t > 80
0.999 if P̄_t < 60
1 otherwise
}
The token supply for day t+1 is calculated as:
S_{t+1} = S_t * α_t
Induction proof for supply bounds:
Therefore, the supply remains bounded for all t.
Let R be the base annual reward rate (5% or 0.05).
Let A_i be the amount staked by validator i.
Let M_i be the performance multiplier for validator i, defined as:
M_i = P_i / 50
The daily reward for validator i on day t is calculated as:
R_i_t = (A_i * R / 365) * M_i * α_t
Let Δ_t be the total rewards distributed on day t:
Δ_t = ∑_{i=1}^n R_i_t
If α_t > 1 (supply increasing):
Mint Δ_t new tokens for distribution
If α_t < 1 (supply decreasing):
Distribute Δ_t tokens from the reserve pool
Let RP_t be the reserve pool balance on day t.
RP_{t+1} = RP_t - Δ_t (when α_t < 1)
Assumption check: Ensure RP_t ≥ Δ_t at all times to prevent insufficient funds for reward distribution.
Initial Reserve Pool: RP₀ = 0.2 * S₀ = 200,000,000 EIT
Daily Reserve Pool update:
RP_{t+1} = RP_t + (S_{t+1} - S_t) - Δ_t
This ensures that supply decreases add to the reserve pool, while rewards are deducted.
Each validator's performance score is updated daily based on their activities and adherence to protocol rules. The exact scoring mechanism would depend on the specific requirements of the indemnification system.
The system should include a governance mechanism to adjust parameters such as the base reward rate R, performance score thresholds, and supply adjustment factors. This ensures the system can adapt to changing conditions.
Let t ∈ ℕ represent days since system inception.
Let V = {1, …, n} be the set of validators.
Assumption: The reserve pool will always have sufficient funds for reward distribution when the supply is decreasing.
Mitigation: Implement a minimum reserve pool balance threshold. If this threshold is approached, gradually reduce rewards or mint a small amount of new tokens to prevent reserve pool depletion.
Assumption: The performance scoring system is resistant to manipulation.
Mitigation: Implement additional checks and balances, such as peer review of performance scores or using external data sources to validate performance claims.
Assumption: The supply adjustment mechanism will maintain price stability.
Mitigation: Monitor price volatility and implement circuit breakers or more granular supply adjustments if needed.
Assumption: Validators will always have an incentive to perform well.
Mitigation: Regularly review and adjust the reward structure to ensure it remains competitive and encourages desired behaviors.
By following this detailed workflow and considering the potential faulty assumptions, we can create a robust and adaptive system for dynamic supply adjustment and performance-based rewards in the indemnification protocol.
