Water is critical for all human activity and in light of climate change, a careful handling of water is more vital than ever. A Block chain allows us to do this.
Advantages
- Infrastructure already in place for highly developed areas, IE water meters.
- Points to areas of use with a high degree of accuracy.
- Refines data on our ecological needs.
- Able to forecast future water requirements.
Challenges
- Areas with non-metered water or areas lacking required infrastructure for water metering
Incentives could be given on basis of conservation or locating inefficiencies within the system. As this is operating on a peer to peer network, voting could be done far more effectively for both funding improvements and potential crisis's could be closely monitored.
