Blockchain Toilet Paper Dispenser

Par 7

Question 29advancedSheet 1750822302

Deep Breath

A blockchain enthusiast created a decentralized toilet paper dispensing system. Each sheet requires proof-of-work mining and distributed consensus across bathroom stalls. The system occasionally runs out of gas during critical moments and nobody can remember why this needed blockchain. Your task: Mine toilet paper transactions while maintaining bathroom functionality.

Why You're Doing This

You're building a blockchain system applied to resource dispensing with real-world urgency constraints. This tests distributed consensus, transaction processing, gas fee optimization, and maintaining system utility. It's like Ethereum but for bathroom emergencies and equally likely to fail when you need it most.

Take the W

✓ Processes toilet paper transactions through blockchain consensus
✓ Handles gas fees and network congestion appropriately
✓ Maintains emergency protocols for urgent bathroom needs

Hard L

✗ Fails to dispense during bathroom emergencies
✗ Allows infinite toilet paper creation
✗ Gas fees exceed reasonable bathroom budget

Edge Cases

⚠ Network congestion during mass bathroom emergency at large venue
⚠ Gas price manipulation attacks during peak bathroom usage hours
⚠ Smart contract bugs causing negative toilet paper balance states

Input Format:

ToiletPaperBlockchain with emergency_protocols and dignity_preservation_features

Expected Output:

DispenseTransaction with urgency_handling and fee_optimization

Example:

{"sheets": 3, "urgency": "high", "gas_price": "20_gwei", "emergency": true} → {"dispensed": true, "cost": "minimal", "protocol": "emergency_activated", "dignity": "preserved"}

Input Format:

S (sheets_needed), U (urgency_coefficient), G (gas_price), N (network_congestion)

Expected Output:

total_transaction_cost, dispensing_probability, emergency_override

Example:

S=3, U=0.95, G=20_gwei, N=high_congestion → cost=emergency_minimal, probability=100%, override=activated

Hints

💡 Emergency protocols override normal blockchain consensus for basic human dignity
💡 Gas fee optimization should never compromise bathroom functionality
💡 High urgency situations require immediate dispensing regardless of network congestion
