Validator Guide - RPi (WIP)

An initial set of instructions for running a Jupiter Callisto validator. These instructions are intended to be followed by competent Linux System admins. Lack of knowledge could lead to loss of funds!

Intro
These instructions were written for the Jupiter Testnet (NOT MAINNET) during initial testing of the Cosmos-based Jupiter blockchain. These settings will not work for mainnet and may need to be updated for future testnets. Please report any problems in Jupiter Discord​
Running a Validator
Raspberry Pi v4 have a minimum of 4GB, so swap space is not necessary.
Install Go
wget https://go.dev/dl/go1.18.3.linux-armv64.tar.gz
sudo su
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.3.linux-armv64.tar.gz
export PATH=$PATH:/usr/local/go/bin
source ~/.profile
go version
Install jq
sudo apt install jq
Clone the Jupiter repository
git clone https://github.com/jupiter-project/jupiter-ng.git
cd jupiter-ng
Move jupiterd binary:
sudo mv ./jupiterd /usr/local/bin
Run initializer:
./testnet-init.sh
Let it run until you see output that blocks are being executed & committed. Then kill it with CTRL + C
Move Genesis:
cp ./genesis.json ~/.ethermintd/config/genesis.json
Delete Chain Data from Init:
Warning: This command can be dangerous if not copied correctly!
cd ~/.ethermintd/data/
rm -rf application.db blockstore.db cs.wal evidence.db snapshots state.db tx_index.db
cd ~/jupiter-ng
Add a good seed to seeds= or persistent_peers= in ~/.ethermintd/config/config.toml:
# Comma separated list of seed nodes to connect to
​
seeds = ""
​
# Comma separated list of nodes to keep persistent connections to
​
persistent_peers = "[email protected]:26656"
Fire up the box
jupiterd start --pruning=nothing --evm.tracer=json --trace --log_level info --minimum-gas-prices=0.0001ajup --json-rpc.api eth,txpool,personal,net,debug,web3,miner --api.enable
