What is storage rent on Ergo?

Storage rent is Ergo's solution to state bloat. Boxes (UTXOs) that remain unspent for 4+ years can have a small fee deducted by miners. This incentivizes cleaning up unused state, provides long-term miner revenue after emission ends, and keeps the blockchain sustainable. Lost coins eventually return to circulation instead of being locked forever.

• 4-year grace period: no rent for actively used boxes
• Miner revenue: sustainable income after block rewards end
• State cleanup: incentivizes removing unused data
• Lost coin recovery: dormant coins gradually return to circulation
• Sustainability: prevents infinite state growth
