Node installation

Setup validator name

git clone https://github.com/dymensionxyz/dymension && cd dymension
git checkout v4.0.0
make install

dymd version --long | grep -e version -e commit
# version: 5bbee2a0c74474bc159bd28bd2f70782e2352dcd
# commit: v4.0.0

We initialize the node to create the necessary configuration files

dymd init UTSA_guide --chain-id dymension_1100-1

Download Genesis

wget -O $HOME/.dymension/config/genesis.json "https://github.com/dymensionxyz/networks/raw/main/mainnet/dymension/genesis.json"

# Проверим генезис
sha256sum ~/.dymension/config/genesis.json
# 44a4440d7515cd3b7245bc8ed0ccb1e9ecadd8f24da5508f325f9df0509f916b

At this stage, we can download the address book

wget -O $HOME/.dymension/config/addrbook.json "https://share.utsa.tech/dymension/addrbook.json"

Set up node configuration

dymd config chain-id dymension_1100-1
dymd config keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"20000000000adym\"/;" ~/.dymension/config/app.toml
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.dymension/config/config.toml
peers="a53c0884c5225f13a99e0af9ef04cd50facee668@84.203.117.234:26691,879aca1f688346ca7a3901aa1e9fc62f48112f01@65.109.124.111:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.dymension/config/config.toml
seeds="[e-mail]:25155,[e-mail]:14659"
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.dymension/config/config.toml

timeout_propose="1.8s"
timeout_commit="500ms"

sed -i "s/^timeout_propose *=.*/timeout_propose = \"$timeout_propose\"/" $HOME/.dymension/config/config.toml
sed -i "s/^timeout_commit *=.*/timeout_commit = \"$timeout_commit\"/" $HOME/.dymension/config/config.toml

(OPTIONAL) Set up pruning

pruning="custom"
pruning_keep_recent="1000"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.dymension/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.dymension/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.dymension/config/app.toml

(OPTIONAL) Set up indexer

indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.dymension/config/config.toml

(OPTIONAL) Enable/Disable Snapshots

snapshot_interval=1000
sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.dymension/config/app.toml

Create a service file

tee /etc/systemd/system/dymd.service > /dev/null <<EOF
[Unit]
Description=dymd
After=network-online.target

[Service]
User=$USER
WorkingDirectory=/root/.dymension
ExecStart=$(which dymd) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable dymd
systemctl restart dymd && journalctl -u dymd -f -o cat

If peers do not cling for a long time or you see errors error: wrong Block.Header.AppHash, you need to use State sync or boot from a Snapshot
