# Geth - Enabling path-based state storage

{% hint style="info" %}
As of [Geth v1.13.0](https://blog.ethereum.org/2023/09/12/geth-v1-13-0), a new database model for storing the Ethereum state, which is both faster than the previous scheme, and also has proper pruning implemented. 

No more junk accumulating on disk and no more guerilla (offline) pruning!
{% endhint %}

### :tada: Enjoy performance improvements

### :robot: How to enable PBSS for existing installations

{% hint style="info" %}
Before continuing please understand the following:

* Synching Geth can take hours during which time block proposals can be missed
* Consider using a backup EL/CL if you have many validators
* Enabling PBSS requires a full Geth resync

{% tab title="V2 Staking Setup (Current)" %}

```bash
# Stop geth
sudo systemctl stop execution

#(add --state.scheme=path to the ExecStart line)
sudo nano /etc/systemd/system/execution.service

# reload changes
sudo systemctl daemon-reload

# Delete the old db
# and when asked, delete the state database, but keep the ancient database
# Yes to state db, no to ancient db.
sudo -u execution /usr/local/bin/geth --datadir /var/lib/geth removedb

# Start geth
sudo systemctl start execution
```

{% endtab %}

{% tab title="V1 Staking Setup" %}

```bash
# Stop geth

sudo systemctl daemon-reload

# Delete the old db
# and when asked, delete the state database, but keep the ancient database
# Yes to state db, no to ancient db.
sudo /usr/bin/geth --datadir ~/.ethereum removedb

# Start geth
sudo systemctl start eth1
```
