# Start Solve and Verify
Once [Truebit on Ethereum has started](https://docs.truebit.io/v1docs/getting-started/start-truebit-on-ethereum):
**1. Start Solver using account 0.**
```bash
start solve -a 0
```
**OUTPUT**
{% code overflow="wrap" %}
```bash
info: SOLVER initialized at block 6794618.
```
{% endcode %}
**2. Start Verify using account 1.**
```bash
start verify -a 1
```
**OUTPUT**
{% code overflow="wrap" %}
```bash
info: VERIFIER initialized at block 6795600
```
{% endcode %}
**3. Check if the Solver or Verifier is active.**
```bash
truebit-os:> ps
```
**OUTPUT**
{% code overflow="wrap" %}
```bash
SOLVERS Account 0: 0x2F25f5DF360305977Fef8F6730883a787785B802
VERIFIERS Account 1: 0x353510EF7b01b4BAAd9616ae23d344c5945c6771
```
{% endcode %}
**4. Balances before start.**
