sudo apt-get install git cargo clang cmake build-essential pkg-config openssl libssl-dev protobuf-compiler

2. Installation

git clone https://github.com/0glabs/0g-da-node.git
cd $HOME/0g-da-node

./dev_support/download_params.sh

3. On the first run of DA node, it will register the signer information in DA contract. To generate a BLS private key if don't have:

cargo run --bin key-gen

4. Create Config File

cp $HOME/0g-da-node/config_example.toml $HOME/0g-da-node/config.toml

Configuration

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"
