Hardware prerequisites
To prepare for the upcoming testnet and network upgrades the Dymension validators and full nodes should be prepared with the following minimum recommended hardware requirements:
100mbps network bandwidth
Preparing the server
Copy sudo apt update && sudo apt upgrade -y
sudo apt install curl lz4 tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y
Install Go
Copy cd $HOME
ver="1.21.3"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile go version
Copy cd $HOME
git clone https://github.com/dymensionxyz/dymension.git
cd dymension
git checkout v2.0.0-alpha.8
make install
Verify that the Dymension full node is installed correctly
Example :
name: dymension
server_name: dymd
version: v2.0.0-alpha.8
commit: 080bbb9ede90170f84a3f4f3665c179ea8742716
Copy dymd init mynode --chain-id=froopyland_100-1
dymd config chain-id froopyland_100-1
Create Wallet:
Copy to restore exexuting wallet, use the flag recover
Copy dymd keys add OR dymd keys add --recover
Download Genesis:
Copy wget https://raw.githubusercontent.com/111STAVR111/props/main/Dymension/Testnet/genesis.json -O $HOME/.dymension/config/genesis.json
Download Addrbook:
Copy wget -O $HOME/.dymension/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Dymension/Testnet/addrbook.json"
Copy
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0udym\"/;" ~/.dymension/config/app.toml
external_address=$(wget -qO- eth0.me)

sed -i 's/max_num_outbound_peers =.*/max_num_outbound_peers = 50/g' $HOME/.dymension/config/config.toml
Set pruning
Copy sed -i \
-e 's|^pruning *=.*|pruning = "custom"|' \
-e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
-e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
-e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
