Meter Reading Certification at a utility company
Stage 1 | Loading
The operator uploads a photo of the meter through the b-cert app of his/her smartphone, certifying the reading.
Stage 2 | Certification
b-cert periodically certifies all files in a massive way and fully independently guaranteeing date and unchageability of readings.
Stage 3 | Storage
The files are uploaded to a long-term digital storage system, in case of any disputes.
Stage 4 | Riception
The client receives the b-cert warranty certificate on the invoice and can contact an operator to view the corresponding photo.
Implementation of an electronic ballot box for managing the entire voting flow for administrative elections of an agency
Stage 1 | Set-Up
OTP submittal: each registered voter receives a unique (anonymous) key created via QR-code and proceeds with the subsequent registration.
User Generation: an account is created on the Blockchain, called "wallet" to allow subsequent voting and verification operations.
Wallet initialization: the agency’s wallet is created and filled with the necessary cryptocurrency (voting fund) which is transferred to all wallets registered in the previous stage to allow future voting.
Stage 2 | Voting
Vote opening: the agency starts the voting process by calling up the smart contract for voting. The user, after having received the notification on the wallet, votes.
Vote: voting calls for the encryption of the chosen list with the public key of the agency and subsequent writing on the blockchian of the encrypted vote.
Voting collection: voting collection shows a method (API) of the smart contract solely to the agency to learn in real time the number of voters who voted.
Vote closing: The agency calls up a private smart contract method to end the vote collection process. At this stage it will be possible to know how many voters voted.
Stage 3 | Ballot
Vote decryption: the encrypted information (individual votes) is decrypted with the private key of the vote (secret) and finally the vote is written in plain text on the ballot's smart contract. Ballot: the ballot process (smart contract) requires the real-time calculation of the voting results.
Verification: each voter, through the ballot smart contract, will be able to call up the methods to know the ballots in real time.
Publication of Results: the voting ends with the publication of the results
