1. \--log\_folder ./tmp\_log is used to set the log file.
2. \--min\_peers 4 is used to set peer numbers.
3. Our bootnode is /ip4/64.71.185.50/tcp/19876/p2p/QmfWjyu4V5SLMYbNCmLu38Lw1eQ4KgsXigyupoWdL36dSv
4. network\_type=localnet is used to set as localnet
5. \--run.shard=0 is used to connect to the shard0, --run.shard=1, --run.shard=2, --run.shard=3 for other shards.
