How are WAL storage rewards calculated on Sui

storage rewards are calculated and settled on Sui’s Move smart contracts epoch by epoch roughly 2 weeks proportionally distributing user prepaid fees plus subsidies based on stake share node commissions and data served Core Pricing and Flow Users prepay upfront for storage contracts linear in data size and epochs User_Price = Storage_Price × (1 - Subsidy_Rate) where Storage_Price reflects fiat pegged costs roughly 5x replication overhead and Subsidy_Rate bootstraps early adoption from a 10 percent token pool Funds lock in Sui objects rewards stream linearly over the contract’s life not dumped at once matching ongoing node costs Reward Formulas Per Epoch Per Blob Served At epoch end Sui settles via 4 rules Node_Revenue operator commission = Storage_Price × (1 + Subsidy_Rate) × Commission Staker_Revenue net after commission = Storage_Price × (1 + Subsidy_Rate) × (1 - Commission) Subsidy_Payment protocol top up = Storage_Price × 2 × Subsidy_Rate bridging user payments to full operator staker compensation Individual stakers get their share proportional to delegated WAL / node’s total stake only if node is in Current Committee Computation Steps on Sui Committee Election Delegated WAL stake elects nodes higher stake more slivers blobs assigned Attestations and PoA Nodes prove availability Sui verifies certs onchain Proportional Allocation Rewards = Node’s blobs served / total × epoch revenue pool split by formulas above Settlement Move contracts auto distribute WAL to nodes stakers slashing 10 to 50 percent burn for failures Yields scale with TVS higher usage more fees per stake early APY low 4 to 8 percent rising to 15 percent plus at scale as subsidies fade Commissions 5 to 20 percent incentivize operators governance tunes parameters Rewards accrue continuously claimable epochally $WAL #Walrus @WalrusProtocol
