A system created for the generation of certificates from worshops and lectures held at CTIC - Coordenadoria de Internet e Data Center

Check the Wiki page for the draft of the aims, enhancements and operation of this system.

There's two functions created for the database: create_user and generate_cert

To create a user, one need to pass as argument to function his Full Name, CPF and the name of the course he is attending to. After the execution, the Private Key of the user is returned, which should be saved somewhere to generate his cert futurelly.

As for generate_cert, one has to pass user Full Name, CPF, course's name and his private key to validate the transaction at the database and afterwards generate his certificate. The certificate is identified by user's CPF and stored on a directory called certificates/ on the current script directory;the function returns a OK message at the end.

• Docker:

$ docker pull bigchaindb/bigchaindb:all-in-one

$ docker run \
  --detach \
  --name bigchaindb \
  --publish 9984:9984 \
  --publish 9985:9985 \
  --publish 27017:27017 \
  --publish 26657:26657 \
  --volume $HOME/bigchaindb_docker/mongodb/data/db:/data/db \
  --volume $HOME/bigchaindb_docker/mongodb/data/configdb:/data/configdb \
  --volume $HOME/bigchaindb_docker/tendermint:/tendermint \
  bigchaindb/bigchaindb:all-in-one

There's also a docker-compose.yaml in BigchainDB repo that easily deploys a one-node BigchainDB network.

For a 4 nodes network, check stack.sh script on BigchainDB repo.
