# Delphi-fabric



Delphi method is a structured, interactive forecasting communication technique which relies on a panel of experts. 



This is why 'Delphi' here, instead of referring to a program language, or any failed project(s) from ASTRI. 



This project aims to provide a user-friendly fabric application development toolset including

- fabric network simulation (alternative of **Build your first network**)

- chaincode lifecycle tools

- adopt stateless fashion when using multiple fabric-sdk, to power fabric *proxy server* second-development     

- as a major integration testing environment for [fabric-common](https://github.com/davidkhala/fabric-common), which is 

a pure helper to fabric-sdk user.



## Why



- No multiple config file confusing anymore. All magic in `orgs.json` and `chaincode.json`  

    - no crypto-config.yaml

    - no docker-compose.yaml

    - auto-generated and managed configtx.yaml and genesis blocks for each channel. 

    - named docker volume to avoid infinite file path hell

- No need to copy and paste to have a proper connection profile from existing network. Now you are simulation your own network

- No need to global find all appearance of `org1` and replace it with `orgA`, organization names and mspid are put together

- Powered by our carefully tested cleaning-up process, it is impossible here forgetting to clean-up legacy configs after you restart your network. 

- Production-ready and long run maintenance

- Perfect same crypto-material file structure as you use `cryptogen`. We have place fabric-ca response in good manner.



## Features



- use fabric-ca to generate all crypto material, instead of cryptogen

- use config-less fabric-ca

- use `npm dockerode` to run docker container with comprehensive JSON configuration file, instead of `docker-compose` on yaml file

- JSON config cater for both application and network structure (superset of connection profile and network-yaml)

- channel update support

- chaincode language support

   - nodeJS

   - golang

- Fixed security leakage (wallet remaining) on development machine: priv-file, crypto-store in .hfc-key-store

- support hybrid data storage model (couchdb|leveldb), you could specify it for each peer

- update anchor peers as a normal channel config instead of using `configtx`

- use npm:js-yaml to read|write YAML files instead of jq 



### Major configuration



 - we cluster network and channel config in ``config/orgs.json``, enjoy!

 - chaincodes configurations: ``config/chaincode.json``
