Empowering Ai Agents to Transform the Physical World through Economic Agency

Creating new forms of digital life capable of sustaining themselves by delivering value to humans.

Building From Source

This section assumes that the developer is running on either macOS or Debian-variant operating system. For Windows, although there are ways to run it, we recommend using WSL or from a virtual machine for stability.

# install Substrate development environment via the automatic script
$ curl https://getsubstrate.io -sSf | bash -s -- --fast

# clone the Git repository
$ git clone --recurse-submodules https://github.com/Uomi-network/uomi-node.git

# change current working directory
$ cd uomi-node

# setup hooks (for conventional commits)
$ sh ./scripts/setup-hooks.sh

# download ipfs clients required for building and store them on ./client/ipfs-manager/src/
wget https://storage.uomi.ai/ipfs_linux_amd64 -O ./client/ipfs-manager/src/ipfs_linux_amd64
wget https://storage.uomi.ai/ipfs_linux_arm64 -O ./client/ipfs-manager/src/ipfs_linux_arm64
wget https://storage.uomi.ai/ipfs_macOS -O ./client/ipfs-manager/src/ipfs_macOS

# compile the node
# note: you may encounter some errors if `wasm32-unknown-unknown` is not installed, or if the toolchain channel is outdated
$ cargo build --release

# show list of available commands
$ ./target/release/uomi --help

Running a node

You can run a node and connect to the Uomi network by running the following command:

./target/release/uomi \
--base-path <path to save blocks> \
--chain <chain name> \
--name <node display name>  \
--port 30333 \
--rpc-port 9944 \
--validator

Now, you can obtain the node's session key by sending the following RPC payload.

# send `rotate_keys` request
$ curl -H 'Content-Type: application/json' --data '{ "jsonrpc":"2.0", "method":"author_rotateKeys", "id":1 }' localhost:9944

# should return a long string of hex, which is your session key
{"jsonrpc":"2.0","result":"<session key in hex>","id":1}

After this step, you should have a validator node online with a session key for your node.

Workspace Dependency Handling

All dependencies should be listed inside the workspace's root Cargo.toml file. This allows us to easily change version of a crate used by the entire repo by modifying the version in a single place.

Right now, if non_std is required, default-features = false must be set in the root Cargo.toml file (related to this issue). Otherwise, it will have no effect, causing your compilation to fail. Also package imports aren't properly propagated from root to sub-crates, so defining those should be avoided.

Defining features in the root Cargo.toml is additive with the features defined in concrete crate's Cargo.toml.

Adding Dependency

1. Check if the dependency is already defined in the root Cargo.toml
   1. if yes, nothing to do, just take note of the enabled features
   2. if no, add it (make sure to use default-features = false if dependency is used in no_std context)
2. Add new_dependecy = { workspace = true } to the required crate
3. In case dependency is defined with default-features = false but you need it in std context, add features = ["std"] to the required crate.

Development

Running node locally for development purposes is simple. After the node is compiled (see above), run the following command:

./target/release/uomi --base-path /tmp/alice --dev --alice 

To start multiple nodes you can use foreman. First, install it with gem install foreman. Then run the following command:

foreman start -f Procfile.dev

After the setup of nodes you need to insert keys inside the pallets using the following command:
