+# Auth_Network
+
+This is a school project for Cryptography teached by Dr.Nguyen Tan Khoi at Danang University of Science and Technology.
+
+Implement a hyperledger fabric network named Asset Authentication Network
+
+# Prerequisites:
+- Ubuntu 18
+- Docker, docker compose
+- npm, node
+- Go
+- Hyperledger Fabric Binaries and docker images
+-> they have to be added into linux path
+
+# Run:
+1. Delete all old cryptographic file in api 1.4
+2. Regenerate all crypto material in artifact by rerunning artifacts/channel/create-artifacts.sh
+3. Start the network by running start.sh
+4. Start the api server by running "node api-1.4/app.js" 
+
+# Interact with the api server using these endpoints:
+1. Import this collection of endpoint using Postman: https://www.getpostman.com/collections/401b1a02ed1330385449
+2. Config your collection variable to suitable values.
+3. First to register a user to get an access token.
+4. Use that access token to trigger all other endpoints.
+
+# Features:
+1. Create,
+2. Manage ownership,
+3. and delete an ownership.
