First, complete the basic Rust setup instructions. If you are a Windows user the this link is for you. But native development of substrate is not very well supported.
Use Rust's native
cargo command to build and launch the asylum node:
cargo run --release -- --dev --tmp
cargo run command will perform an initial build. Use the following command to build the node
without launching it:
cargo build --release
Once the project has been built, the following command can be used to explore all parameters and subcommands:
cargo run command will launch a temporary node and its state will be discarded after
you terminate the process. After the project has been built, there are other ways to launch the
Single-Node Development Chain
This command will start the single-node development chain with non-persistent state:
Purge the development chain's state:
./target/release/node-asylum purge-chain --dev
Start the development chain with detailed logging:
RUST_BACKTRACE=1 ./target/release/node-asylum -ldebug --dev
Development chain means that the state of our chain will be in a tmp folder while the nodes are running. Also, alice account will be authority and sudo account as declared in the genesis state. At the same time the following accounts will be prefunded:
In case of being interested in maintaining the chain' state between runs a base path must be added so the db can be stored in the provided folder instead of a temporal one. We could use this folder to store different chain databases, as a different folder will be created per different chain that is ran. The following commands shows how to use a newly created folder as our db base path.
// Create a folder to use as the db base path
$ mkdir my-chain-state
// Use of that folder to store the chain state
$ ./target/release/node-template --dev --base-path ./my-chain-state/
// Check the folder structure created inside the base path after running the chain
$ ls ./my-chain-state
$ ls ./my-chain-state/chains/
$ ls ./my-chain-state/chains/dev

Connect with Polkadot-JS Apps Front-end
Once the node template is running locally, you can connect it with Polkadot-JS Apps front-end to interact with your chain. Click here connecting the Apps to your local node template.

Asylum consists of core and spaces pallets:
- Asylum Blueprints pallet: this module provides functionality for blueprints and items management.
- Asylum Spaces pallet: this module provides functionality for spaces and space pass' management.
