Dapp Water

This is a Dapp that realizes a system aiming to reduce the water consumption through the active participation of citizens in the proposal of policies to incentive people in reducing the demand, in the participation in a election system to elect the best proposal and in the application of the winning proposal.

More in details, the citizens can create and deploy a smart contract (ProposalContract) summarizing their proposal while the election system is managed by another smart contract (ManagerContract).

ProposalContract has also the role of running its proposal in case of victory of the election. During the creation of this the participants may choose between several options to realize their own proposal.

//Enum for elaborate the proposals
     enum What {
             Home, //Monitor consumption of just a citizen
             Block, //Monitor consumption of a group of citizen
             Neighborhood //Monitor consumption of a larger group of citizen
         }
     enum Criteria{
         LessThan, //The entity monitored must respect a certain threshold
         LessPossible //The entity monitored must consume less water as much as he can
     }
     enum Interval { //Period monitored after which incentives are distributed
         Month,
         Trimester,
         Semester
     }

Another smart contract (WaterOracle) aims to retrieve, through the use of an oracle system (Oraclize/Provable), water consumption data, used in the running phase of the winning solution.

Finally, a nodejs backend is proposed to interact with the blockchain (through web3js). A solution with smart contract compiler can be evaluated.

How to use the website

• Page "Home": Just homepage of the site
• Page "Proposal": Page to realize the proposal. Once submitted the ownership of the deployed smart contract is changed to the address of the ManagerContract.
• Page "Vote": Page to ask the permission to vote, available until the beginning of the elections; here you can see the proposals submitted and their content, clicking on one of the listed address, and once you have identified a proposal you can vote it, inserting its index.
• Page "Run": Page to see the execution of the winning node: it calls the oracle and update consumptions list within the winner ProposalContract to keep track of the consumptions and redistribute the incentives.
