# Updates and additional settings

# Upgrade the testnet

These instructions are for full nodes running previous testnets that would like to upgrade to the latest testnet.

# 1. Reset data

Remove the outdated files and reset data:

rm ~/.paloma/config/genesis.json
rm ~/.paloma/config/addrbook.json
palomad unsafe-reset-all

Your node is now in a pristine state, keeping the original priv_validator.json and config.toml. If you had any sentry nodes or full nodes set up before, your node will still try to connect to them but may fail if they haven't also been upgraded.

DANGER

Make sure that every node has a unique priv_validator.json. Do not copy the priv_validator.json from an old node to multiple new nodes. Running two nodes with the same priv_validator.json will cause you to double sign.

# 2. Software upgrade

Now it is time to upgrade the software. Go to the project directory and run:

git checkout master && git pull
go build ./cmd/palomad

TIP

If you have issues at this step, please check that you have a compatible version of GO installed (v1.18+).

The previous command uses master as it contains the latest stable release. See Paloma release page (opens new window) for details on each release.

Your full node is now cleanly upgraded!

# Exporting state

Paloma can export the entire application state to a JSON file. You can use this file for manual analysis or as the genesis file of a new network.

Export state:

palomad export > [filename].json

You can also export a state from a particular height. The following command will export the state after the block height you specify:

palomad export --height [height] > [filename].json

If you plan to start a new network from the exported state, export with the --for-zero-height flag:

palomad export --height [height] --for-zero-height > [filename].json

TIP

For more information on seeds and peers, visit the Tendermint documentation (opens new window).

# Additional Settings

# seed_mode

In seed mode, your node constantly crawls the network and looks for peers. If another node asks it for addresses, it responds and disconnects. Seed mode will not work if the peer-exchange reactor is disabled.

seed_mode = true

# seeds

To manually identify seed nodes, edit the following setting in config.toml.

# Comma separated list of seed nodes to connect to
seeds = "id100000000000000000000000000000000@1.2.3.4:26656,id200000000000000000000000000000000@2.3.4.5:4444"

# persistent_peers

The nodes you specify are the trusted persistent peers that can help anchor your node in the p2p network. If the connection fails, they are dialed and automatically redialed for 24 hours. The automatic redial function uses exponential backoff and stops after 24 hours of trying to connect.

If the value of persistent_peers_max_dial_period is more than zero, the pause between each call to each persistent peer will not exceed persistent_peers_max_dial_period during exponential backoff, and the automatic redial process continues.

# Comma separated list of nodes to keep persistent connections to
persistent_peers = "id100000000000000000000000000000000@1.2.3.4:26656,id200000000000000000000000000000000@2.3.4.5:26656"
