### Hardware Requirement

*   Memory: 16 GB
    
*   CPU: 8 cores
    
*   Disk: 1 TB NVME SSD
    
*   Bandwidth: 100 MBps for Download / Upload
    

### Installation

    git clone https://github.com/0glabs/0g-da-node.git
    git checkout tags/v1.0.1 -b v1.0.1
    cargo build --release
    ./dev_support/download_params.sh
    

### Configuration

Create a \`config.toml\` file:

    log_level = "info"
    
    data_path = "./db/"
    
    # path to downloaded params folder
    encoder_params_dir = "params/" 
    
    # grpc server listen address
    grpc_listen_address = "0.0.0.0:34000"
    # chain eth rpc endpoint
    eth_rpc_endpoint = "https://rpc-testnet.0g.ai"
    # public grpc service socket address to register in DA contract
    # ip:34000 (keep same port as the grpc listen address)
    # or if you have dns, fill your dns
    socket_address = "<public_ip/dns>:34000"
    
    # data availability contract to interact with
    da_entrance_address = ""
    # deployed block number of da entrance contract
    start_block_number = 0
    
    # signer BLS private key
    signer_bls_private_key = ""
    # signer eth account private key
    signer_eth_private_key = ""
    
    # whether to enable data availability sampling
    enable_das = "false"
    

  
Generate a BLS private key:

    cargo run --bin key-gen
