substrate-stencil's Introduction

`substrate-stencil`

A template for kick starting a Rust and Blockchain project using Substrate.

Features

This template includes the minimum required components to start a PoS testnet, inspired by substrate-node-template.

Consensus related pallets: Babe & GRANDPA
Staking related pallets: staking, session, authorship, im-online, offences, utility
Governance related pallets: collective, membership, elections-phragmen, democracy, treasure

Notes: The code is un-audited and not production ready, use it at your own risk.

Getting Started

Follow the steps below to get started.

Rust Setup

First, complete the Dev Docs Installation.

Build and Run

Use the following command to build the node and run it after build successfully:

cargo build --release
./target/release/substrate-stencil --dev

Run public testnet

Modify the genesis config in chain_spec.rs
Build spec, ./target/release/substrate-stencil build-spec --chain staging > stencil-staging.json
Change original spec to encoded raw spec, ./target/release/substrate-stencil build-spec --chain=stencil-staging.json --raw > stencil-staging-raw.json

Start your bootnodes, node key can be generate with command ./target/release/substrate-stencil key generate-node-key.

./target/release/substrate-stencil \
     --node-key <your-node-key> \
     --base-path /tmp/bootnode1 \
     --chain stencil-staging-raw.json \
     --name bootnode1

Start your initial validators,

./target/release/substrate-stencil \
    --base-path  /tmp/validator1 \
    --chain   stencil-staging-raw.json \
    --bootnodes  /ip4/<your-bootnode-ip>/tcp/30333/p2p/<your-bootnode-peerid> \
      --port 30336 \
      --ws-port 9947 \
      --rpc-port 9936 \
    --name  validator1 \
    --validator

Insert session keys
Attract enough validators from community in waiting
Call force_new_era in staking pallet with sudo, rotate to PoS validators
Enable governance, and remove sudo
Enable transfer and other functions

substrate-stencil's Issues

Stash does not have enough balance to bond.

Hi, I just cloned your project and build it.
When I run your node by this command, ./target/release/substrate-stencil --dev, it is getting this error.

Thread 'main' panicked at 'Stash does not have enough balance to bond.', /home/mersaid/.cargo/git/checkouts/substrate-7e08433d4c370a21/fc3fd07/frame/staking/src/pallet/mod.rs:561

This is a bug. Please report it at:

How to add validators on POS node?

Hello, I have forked your current project and I am going to add validators now.
For that, I have researched this tutorial, https://docs.substrate.io/tutorials/get-started/trusted-network/.
As that guide, I have created new Keys and added it on customSpec.json.
But it is getting this error now.

How can I solve this problem?
Please help me.

Is it possible to start a substrate BABE blockchain with no Grandpa authorities and BABE validators?

I'm trying to implement a PoS network on substrate using substrate provided pallets - pallet_session, pallet_staking, pallet_babe, etc. The current Runtime and chain spec implementation is similar to what is found in the substrate repository. I've realized that I need to set Session keys for GenesisConfig before starting the blockchain. I also noticed that the Session keys set for SessionConfig are used to configure the grandpa authorities.

My questions are:

Is there a way to start the blockchain such that no session keys are set?

Do all grandpa authorities need to be hardcoded in the chain spec? If not, how are the authorities added after nodes have gone live?

Getting error in second commit, i.e change aura to babe

I'm following your commits to change POA to POS. In this process after adding second commit, I'm getting this error:

You can find my code repo here: https://github.com/Aideepakchaudhary/POA-to-POS.git

Thanks in advance!
