Node Installation

1. Update System and Install Build Tools

sudo apt update
sudo apt-get install git curl build-essential make jq gcc snapd chrony lz4 tmux unzip bc -y

2. Install Go

rm -rf $HOME/go
sudo rm -rf /usr/local/go
cd $HOME
curl https://dl.google.com/go/go1.22.4.linux-amd64.tar.gz | sudo tar -C /usr/local -zxvf -
cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.profile
go version

3. Install Node

cd $HOME
rm -rf elys
git clone https://github.com/elys-network/elys.git
cd elys
git fetch --all
git checkout v2.3.0
make install
elysd version

4. Initialize Node

Replace NodeName with your own moniker.

elysd init ApeironNodes --chain-id=elys-1

5. Download Genesis

wget -O genesis.json https://snapshots.polkachu.com/genesis/elys/genesis.json --inet4-only

6. Copy Genesis File

cp genesis.json ~/.elys/config/

7. Paste Peers to Config

sudo nano ~/.elys/config/config.toml

Add the peers:

[email protected]:27656,[email protected]:26656,[email protected]:46656,[email protected]:26656,[email protected]:32656

8. Change External Address

PUB_IP=`curl -s -4 icanhazip.com`
sed -e "s|external_address = \".*\"|external_address = \"$PUB_IP:26656\"|g" ~/.elys/config/config.toml > ~/.elys/config/config.toml.tmp
mv ~/.elys/config/config.toml.tmp ~/.elys/config/config.toml

9. Create Service

sudo tee /etc/systemd/system/elysd.service > /dev/null <<EOF
[Unit]
Description=elysd Daemon
After=network-online.target
[Service]
User=$USER
ExecStart=$(which elysd) start
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

10. Reload Daemon and Enable Service

bashCopyEditsudo systemctl daemon-reload
sudo systemctl enable elysd

11. Sync with Statesync

sudo systemctl stop elysd
elysd tendermint unsafe-reset-all --home ~/elys/ --keep-addr-book

Now set up statesync:

SNAP_RPC="https://elys-rpc.polkachu.com:443"
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

Edit the config.toml to use the statesync parameters:

-i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"| ; \
s|^(seeds[[:space:]]+=[[:space:]]+).*$|\1\"\"|" ~/.elys/config/config.toml

12. Verify Config Changes

~/.elys/config/config.toml | grep 'rpc_servers'
more ~/.elys/config/config.toml | grep 'trust_height'
more ~/.elys/config/config.toml | grep 'trust_hash'

13. Launch Node

systemctl restart elysd
journalctl -u elysd -f
