Generate BLS private key

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

Setup config.toml

nano $HOME/0g-da-node/config.toml

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://evmrpc-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 = "<your_VPS__IP>:34000"

# data availability contract to interact with
da_entrance_address = "0x857C0A28A8634614BB2C96039Cf4a20AFF709Aa9"
# deployed block number of da entrance contract
start_block_number = 940000

# signer BLS private key
signer_bls_private_key = ""
# signer eth account private key
signer_eth_private_key = ""
# miner eth account private key, (could be the same as `signer_eth_private_key`, but not recommended)
miner_eth_private_key = ""
# whether to enable data availability sampling
enable_das = "true"
