# dev-node-substrate

It's assumed that these software are installed and running:



  
Rust

  
nightly

  
cargo contract



This project was developed using the [Intellij Community](https://www.jetbrains.com/idea/download/#section=linux) with the [Rust plugin](https://www.jetbrains.com/rust/).



This repository is tracking Substrate's

[`polkadot-v0.9.37`](https://github.com/paritytech/substrate/tree/polkadot-v0.9.37) branch.

The dev-node-substrate is a simple Substrate blockchain which is configured to include the Substrate module for [smart contract](https://use.ink/how-it-works) development using [ink! v4.0](https://github.com/paritytech/ink/releases/tag/v4.0.0).

Note: the consensus from [aura](https://docs.substrate.io/reference/glossary/#authority-round-aura)  & grandpa[(GHOST-based Recursive ANcestor Deriving Prefix Agreement)](https://wiki.polkadot.network/docs/learn-consensus#finality-gadget-grandpa) was changed to manual-seal([sp_consensus](https://docs.rs/sp-consensus/latest/sp_consensus/)/[sc_consensus](https://docs.rs/sc-consensus/latest/sc_consensus/)) where blocks are authored at every transaction.



[ink! CLI version](https://use.ink/getting-started/setup#ink-cli).

```bash

cargo contract --version

```

The directory will be assigned with a Rust toolchain with [rustup override](https://rust-lang.github.io/rustup/overrides.html#directory-overrides).

```bash

rustup show

```

Note:The nightly-2023-02-09 is set by the [rust-toolchain.toml](https://github.com/gcp-development/dev-node-substrate/blob/main/rust-toolchain.toml) file.
