This example shows how to use Trust Graph for code execution only on trusted peers. There are some `trusted_computation` which can only be performed on a trusted peer. The label is determined by the presence of the certificate from `INIT_PEER_ID` to this peer. We use peer id from [`example_secret_key.ed25519`](../example_secret_key.ed25519) as `INIT_PEER_ID` since every node bundled with the certificate issued to this key, it should be used only for test purposes.
3. It takes some time depending on your machine for node to start and builtin services deployed. Wait for this log line: `[2022-07-06T11:33:50.782054Z INFO particle_node] Fluence has been successfully started.`
4. Go back to `../example`
5. Run `npm i`
6. Run `npm run start local`
## Expected output
After successful execution you will get this result:
```
In this example we try to execute some trusted computations based on trusts
