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, 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
