When To Use Blockchain Technologies?

• To create autonomous, independent, non-centralized, open system
• When financial incentives are needed
• For micro-transactions
• Where credit cards and bank transfer are hard or impossible to be used
• To store data that cannot be manipulated in any way
• ...

Distributed Parking

• Every citizen can register with his vehicle license plate
• Parking tokens are pre minted and distributed to each registrant equally
• The tokens are used to compensate someone to free his street parking spot
• When someone is going to free a parking spot he declares that in the app and sets a timeout and location via GPS and makes a deposit in tokens
• If someone is looking for a parking spot in that area he can declare interest and deposit tokens
• The owner of the spot sees all cars interested with all their data - color, mode, license plate etc. He can monitor their movement on the map via GPS
• When the owner sees the other car they can make visual signals and exchange their places
• Everyone confirms if the exchange has happened and the corresponding token transfers are made
• The tokens cannot be sold. They are used solely for peer 2 peer compensation
• This model encourages drivers to register their cars in the city they live (no aliens)

P2P Improper Parking Reporting

• When someone sees improperly parked vehicle he can report this with a special app
• He takes pictures, writes down the license plate and type comments
• The report can be confirmed by many parties
• All parties deposit tokens for a bigger engagement
• The violator has some time (days) to pay penalty in a form of tokens
• If the penalty is not paid the report is sent to the authorities
• They may require witness testimony
• In that case reporters may give their testimony
• If they prove their testimony by uploading documents they receive tokens
• The tokens are given for free to registered reporters
• The tokens are sold to those who need to pay a fine
