Logchain-S

Runtime Environment

WE RECOMMEND USERS TO INSTALL RUNTIME ENVIRONMENT IN Windows and LINUX OPERATION SYSTEM(ubuntu). THE GUIDE FOR SETTING RUNTIME ENVIRONMENT ARE APPLIED FOR LINUX OPERATION SYSTEM FOR THE MOMENT!!

Get Started

Windows Environment: 

• git clone https://github.com/jaesunkim/logchain-s.git
  • After installing python 3.6, go to the path where pip is installed and open the cmd wind
  • pip install PyQt5
  • pip install netifaces
• • pip install flask

Linux Environment:

• • sudo apt-get update
  • sudo reboot
  • sudo apt-get install git-core
• • sudo apt-get install python-pip
  • sudo pip install –upgrade pip
  • sudo pip install flask
  • sudo pip install PyQt5
  • git clone https://github.com/jaesunkim/logchain-s.git
  • Logchain-s
  • git checkout logchain-s
  • git pull
  • sudo pip install netifaces

Blockchain network Environment: 

• Requires three or more nodes
• One is a seed peer and the other nodes are generic peers.
  • Seed peer setting -> modify peermgr.json file
    •  Change the PEER_LIST list in the peermgr.json file (for authentication peers)
  • Generic peer setting -> modify peerconnector.json
    • Change the PEER_MGR_LIST  in the peermgr.json file (for authentication peers)
  • Execute  python./launcher/logchain_launcher_for_trustpeer.py
  • Execute  python ./launcher/logchain_launcher_for_genericpeer_restapi_node.py

Http REST API:

• Save transaction
  • URL:/tx/save/, Method : POST, URL parameters : N/A, json
• Deploy  smart contract
  • URL: /contract/deploy/, Method : POST, URL parameters : N/A, json
• Execute smart contract
  • URL: /contract/execute/, Method : POST, URL parameters : N/A
• Show all saved transactions
  • URL: /info/tx/, Method : GET, URL parameters : N/A
• Show all deployed smart contracts
  • URL: /info/contract/deployed/, Method : GET, URL parameters : N/A
• Show all results of deployed smart contracts
  • URL: /info/contract/deployed/result/, Method : GET, URL parameters : N/A

Demo App:

• Demo Rest API
• Demo_save tx
