PoSp Scoring
PoSp rewards validators for providing decentralized storage, ensuring data availability for AI applications. The score for a validator i is calculated as: PoSp_Score_i = (Storage_i × Uptime_i) / Total_Network_Storage
Here
Storage_i: The amount of storage the validator contributes, e.g., ≈ 1TB.
Uptime_i: The percentage of time the storage is available, e.g., ≈ 0.99 (99%).
Total_Network_Storage: The total storage across all validators, e.g., ≈ 100TB.
For a validator contributing 1TB with 99% uptime in a network with 100TB total storage, the score is: PoSp_Score_i = (1 × 0.99) / 100 = 0.0099
PoSp challenges, which use Merkle proofs (≈ 1KB in size), occur approximately every BABE epoch (4 hours) and are verified in ≈ 5 milliseconds through the storage verification pallet.
