Using Source Code
To install and run a subtensor node by compiling the source code, follow the below steps.
We have not tested subtensor node installation scripts on any cloud service. In addition, if you are using Runpod cloud service, then note that this service is already containerized. Hence, the only option available to you for Runpod is to install a subtensor node by compiling from source, as described below. Note that we have not tested any subtensor installation steps on Runpod.
Install basic packages
Install the basic requirements by running the below commands on a Linux terminal.
sudo apt-get update
sudo apt install -y build-essential clang curl git make libssl-dev llvm libudev-dev protobuf-compiler
Install the basic requirements by running the below command on macOS.
brew install protobuf
Install Rust
Next, install Rust and update the environment by running the following commands:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env
Next, install Rust toolchain:
rustup default stable
rustup update
rustup target add wasm32-unknown-unknown
rustup toolchain install nightly
rustup target add --toolchain nightly wasm32-unknown-unknown
Compile subtensor code
Next, to compile the subtensor source code, follow the below steps:
- Clone the Subtensor repository:
git clone https://github.com/opentensor/subtensor.git
- Change to the Subtensor directory:
cd subtensor
- Switch to
mainbranch:
git checkout main
- Remove any previous chain state:
rm -rf /tmp/blockchain
- Install Subtensor by compiling with Cargo:
cargo build -p node-subtensor --profile=production --features=metadata-hash
Run the subtensor node
You can now run the public subtensor node either as a lite node or as an archive node. See below:
Lite node on mainchain
To run a lite node connected to the mainchain, execute the below command (note the --sync=warp flag which runs the subtensor node in lite mode):
./target/production/node-subtensor --chain raw_spec_finney.json --base-path /tmp/blockchain --sync=warp --port 30333 --max-runtime-instances 32 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9944 --bootnodes /dns/bootnode.finney.chain.opentensor.ai/tcp/30333/ws/p2p/12D3KooWRwbMb85RWnT8DSXSYMWQtuDwh4LJzndoRrTDotTR5gDC --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external
Archive node on mainchain
To run an archive node connected to the mainchain, execute the below command (note the --sync=full which syncs the node to the full chain and --pruning archive flags, which disables the node's automatic pruning of older historical data):
./target/production/node-subtensor --chain raw_spec_finney.json --base-path /tmp/blockchain --sync=full --pruning archive --port 30333 --max-runtime-instances 32 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9944 --bootnodes /dns/bootnode.finney.chain.opentensor.ai/tcp/30333/ws/p2p/12D3KooWRwbMb85RWnT8DSXSYMWQtuDwh4LJzndoRrTDotTR5gDC --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external
Lite node on testchain
To run a lite node connected to the testchain, execute the below command:
./target/production/node-subtensor --chain raw_spec_testfinney.json --base-path /tmp/blockchain --sync=warp --port 30333 --max-runtime-instances 32 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9944 --bootnodes /dns/bootnode.test.finney.opentensor.ai/tcp/30333/p2p/12D3KooWPM4mLcKJGtyVtkggqdG84zWrd7Rij6PGQDoijh1X86Vr --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external
Archive node on testchain
To run an archive node connected to the testchain, execute the below command:
./target/production/node-subtensor --chain raw_spec_testfinney.json --base-path /tmp/blockchain --sync=full --pruning archive --port 30333 --max-runtime-instances 32 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9944 --bootnodes /dns/bootnode.test.finney.opentensor.ai/tcp/30333/p2p/12D3KooWPM4mLcKJGtyVtkggqdG84zWrd7Rij6PGQDoijh1X86Vr --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external
