Using Source Code

To install and run a subtensor node by compiling the source code, follow the below steps.

Not tested on cloud

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.

On Linux
sudo apt-get update 
sudo apt install build-essential
sudo apt-get install clang
sudo apt-get install curl
sudo apt-get install git
sudo apt-get install make
sudo apt install --assume-yes git clang curl libssl-dev protobuf-compiler
sudo apt install --assume-yes git clang curl libssl-dev llvm libudev-dev make protobuf-compiler

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 repo:

git clone https://github.com/opentensor/subtensor.git

cd into the subtensor directory:

cd subtensor

Make sure you are on the main branch. If not, switch to it:

git checkout main

Remove previous chain state:

rm -rf /tmp/blockchain 

Install subtensor by compiling with cargo:

cargo build --release --features=runtime-benchmarks

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):

With --sync=warp setting, for lite node
./target/release/node-subtensor --chain raw_spec.json --base-path /tmp/blockchain --sync=warp --execution wasm --wasm-execution compiled --port 30333 --max-runtime-instances 64 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9933 --ws-port 9944 --bootnodes /ip4/13.58.175.193/tcp/30333/p2p/12D3KooWDe7g2JbNETiKypcKT1KsCEZJbTzEHCn8hpd4PHZ6pdz5 --ws-max-connections 16000 --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external --ws-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):

With --sync=full and --pruning archive setting, for archive node
./target/release/node-subtensor --chain raw_spec.json --base-path /tmp/blockchain --sync=full --pruning archive --execution wasm --wasm-execution compiled --port 30333 --max-runtime-instances 64 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9933 --ws-port 9944 --bootnodes /ip4/13.58.175.193/tcp/30333/p2p/12D3KooWDe7g2JbNETiKypcKT1KsCEZJbTzEHCn8hpd4PHZ6pdz5 --ws-max-connections 16000 --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external --ws-external

Lite node on testchain

To run a lite node connected to the testchain, execute the below command:

With bootnodes set to testnet and --sync=warp setting, for lite node.
./target/release/node-subtensor --chain raw_testspec.json --base-path /tmp/blockchain --sync=warp --execution wasm --wasm-execution compiled --port 30333 --max-runtime-instances 64 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9933 --ws-port 9944 --bootnodes /dns/bootnode.test.finney.opentensor.ai/tcp/30333/p2p/12D3KooWPM4mLcKJGtyVtkggqdG84zWrd7Rij6PGQDoijh1X86Vr --ws-max-connections 16000 --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external --ws-external

Archive node on testchain

To run an archive node connected to the testchain, execute the below command:

With bootnodes set to testnet and --sync=full and --pruning archive setting, for archive node
./target/release/node-subtensor --chain raw_testspec.json --base-path /tmp/blockchain --sync=full --pruning archive --execution wasm --wasm-execution compiled --port 30333 --max-runtime-instances 64 --rpc-max-response-size 2048 --rpc-cors all --rpc-port 9933 --ws-port 9944 --bootnodes /dns/bootnode.test.finney.opentensor.ai/tcp/30333/p2p/12D3KooWPM4mLcKJGtyVtkggqdG84zWrd7Rij6PGQDoijh1X86Vr --ws-max-connections 16000 --no-mdns --in-peers 8000 --out-peers 8000 --prometheus-external --rpc-external --ws-external
