Private Network Tutorial

Overview

This repo provides a description for setting up a ready-to-use private network that is designed to be easily integrated with any business application and Substrate-based blockchain to handle the in-app assets transfers between the application and its users, even facilitating peer-to-peer transfers users.

This turn-key network intends to abstract the implementation complexity for businesses, as well as providing a ready-made package to optimize for a higher level of security, privacy, and performance, and to serve as a template or base-implementation of a highly customizable and performant enterprise-specific blockchain network. It presents a significant step towards easier adoption of blockchain technology for all who are part of the greater Web3 FoundationSubstrate ecosystem.

Cere's Substrate-based private networks will feature:

• A set of turn-key substrate-based packaging and tools that simplify the customization, configuration, testing, and deployment of such a blockchain network.
• Pre-built solutions to create/assign/transfer derivative assets in business to consumer use cases.
• Pre-configured and optimized for feeless transactions and performance.
• Creation of custom derivative assets and automate the transfer to/from user wallets to app wallets by any/app brand.
• Optimization of batch user onboarding and transaction processing for higher throughput situations needed for consumer apps/sites.

Next to that, Cere’s custodial wallets and Decentralized Data Clouds (DDCs) are designed to work in conjunction with this Network.

Who is this repo meant for?

This repo aims to be beneficial to applications & developers who are looking to easily adopt value adding blockchain technology in a turnkey manner.

How does this technology benefit application developers?

• By facilitating Identity abstraction. Check this link out.
• By storing the data for each user in their individual ledger
• By assigning / distributing in-app assets via blockchain technology. Check this link out.

How to start using Private Network

1. Set up the Cere Private Network using instructions below:

Option 1. Set up the Cere Private Network Node using docker run command:

docker run -d --name NAME_OF_YOUR_NODE -p 9944:9944 --entrypoint /usr/local/bin/node-template cerebellumnetwork/turnkey-private-blockchain-network --dev --ws-external

Option 2. Set up the Cere Private Network Node from docker-compose script:

• Clone this repo: git clone https://github.com/Cerebellum-Network/test-scripts
• Up and run node using script: docker-compose up -d node

2. Launch and deploy Assets that can be used in the app

• Create Smart Contract artifacts
• Upload artifacts to the Network
• Deploy Smart Contract to the Network

3. Quickly test key functionalities.

Create a new wallet for the application. In order to do this, you can use this tutorial. Save the wallet JSON ABI and passphrase for further steps.

Option 1: Test key functionalities by using the built-in standard tool.

Run Polkadot UI with the command:

docker run --rm -it --name polkadot-ui -e WS_URL=ws://localhost:9944 -p 81:80 jacogr/polkadot-js-apps:latest

Use Testing Key Functionalities guide to test manually.

Option 2: Test key functionalities by using a programmatic approach.

Once you created an application wallet, use these test scripts to create the user's wallet programmatically and transfer tokens to it.
