**Please note that:**

a. If it is a validator node, shut down bridge as well;
2. **Use Golang version 1.21 to compile delivery and bttc.**

 $ cd delivery
 $ git checkout v1.0.9

```

Since delivery layer v1.0.9, the startup progress has changed from previous 3 scripts( **delivery-bridge-start.sh** , **delivery-server-start.sh** , **delivery-start.sh** ) to 1 script **delivery-start.sh** :

```auto
#!/usr/bin/env sh
set -x #echo on

DELIVERY_HOME_DIR=~/.deliveryd
deliveryd --chain mainnet --home $DELIVERY_HOME_DIR start --node http://0.0.0.0:26657 --laddr tcp://0.0.0.0:1317 --bridge --all --rest-server

```

If it is not a validator node, please remove the `--bridge --all`.
