Extreme Scenarios

Code-derived thresholds · Dynamic critical zones · FVM-aware · Gas cost = GasUsed × EGP where EGP = BaseFee + min(GasPremium, GasFeeCap − BaseFee). Today: BaseFee ≈ 100 attoFIL, GasPremium ≈ 250k — SP tip dominates (99.9%).

⚠ FWSS v1.2.0 upgrade (23 Mar 2026): createDataSet +38% (796M → 1,123M), nextProvingPeriod +23% (124M → 153M). All values reflect the post-upgrade era. addPieces model: 228.72M + 78.20M × K (R²=0.9996, auto-refit daily). Stuck threshold: K > 310.

provePossession 158.67M + 8.485M×log₂(N)
avg 191M (auto-refit daily)		 5×log₂N SLOAD Well-bounded. N=1M → ~317M. Not a disaster risk. 5 challenges × findOnePieceId (log₂N binary search in Sum Tree). MerkleVerify is pure compute. Pyth oracle + BURN_ACTOR. FWSS callback: 2 SSTORE only.
nextProvingPeriod ~153M (was 124M pre-v1.2.0) constant Not a risk alone. CDN adds ~120M (3 rail settlements). Epoch mgmt + FWSS: updatePaymentRates() → modifyRailPayment() ×1–3. Increased post v1.2.0 as more datasets/CDN rails raise settlement cost.
nextProvingPeriod + K removals 153M + K×O(log₂N) per removal K × log₂N Dynamic — see slider. Max queue: 2,000 (contract constant). sumTreeRemove per piece: log₂N iterations of SLOAD+SSTORE. Delete pieceCid (2 SSTORE) + leafCount (1 SSTORE).

terminateService 137M no CDN · 257M CDN constant SP failure: all datasets terminated in one day. terminateRail() ×1 or ×3 (CDN). Rails NOT auto-terminated on dataset delete — explicit call required.
