The objective is to create a web application where we will have several users, these users can be anonymous in case they are not registered, citizen in case the user proceeds to register, if the user is created by the administrator, then the user is accredited which guarantees other privileges and finally the administrator for managing members. If the user has an account on the Platform, he can view the relationships and cast votes, otherwise he will only be able to view, if the user has privileges (is accredited), he can insert relationships.

- Consult users;
- Edit users;
- Delete users;

Creating a Hyperledger Fabric network from scratch — Part IV SDK and Rest API, Iván Alberquilla : https://medium.com/coinmonks/creating-a-hyperledger-fabric-network-from-scratch-part-iv-sdk-and-rest-api-29594e89fefa Hyperledger Fabric SDK for Node.js, Hyperledger: https://github.com/hyperledger/fabric-sdk-node Configuração multi-organizacional microfab, IBM-Blockchain: https://github.com/IBM-Blockchain/microfab
To configure our network, we enter the project directory through WSL and execute the following code.
export MICROFAB_CONFIG='{"port": 8080,"endorsing_organizations":[{"name": "Admin"},{"name": "Credenciado"},{"name": "Cidadao"},{"name": "Anonimo"}],"channels":[{"name":"mychannel","endorsing_organizations":["Admin","Credenciado","Cidadao","Anonimo"]}]}'
And then we create the image in Docker
docker run -e MICROFAB_CONFIG -p 8080:8080 ibmcom/ibp-microfab:0.0.11
The smart contracts can be fund on contract folder
Check the references above.
To run the next project:
Install project:
install nvm sudo apt install curl curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
install node v12.13.1 install node v12.22.0 at least(need to run project) nvm install v12.13.1 nvm install v12.22.0
git clone https://github.com/SergioRCarvalho/PoliticaTransparente.git
open project
nvm use v12.13.0 npm install
now you can run project: npm use v12.22.0 next dev
