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"

go version

Node installation

git clone https://github.com/Entangle-Protocol/entangle-blockchain && cd entangle-blockchain
make install

entangled version --long | grep -e version -e commit
#version: 1.0.1
#commit: "134d9e558aee52abe81fa825272d118f293036f6"

We initialize the node to create the necessary configuration files

entangled init UTSA_guide --chain-id entangle_33133-1

Download Genesis and Config

wget -O $HOME/.entangled/config/genesis.json "https://entangle-public.s3.amazonaws.com/genesis.json"

sha256sum ~/.entangled/config/genesis.json
# ca032fabda646ad98f4709e1e6fd4f06b31435b4a37d62a3539793944bfda692

At this stage, we can download the address book

wget -O $HOME/.entangled/config/addrbook.json "https ://raw.githubusercontent.com/obajay/nodes-Guides/main/Projects/Entangle/addrbook.json"

Set up node configuration

entangled config chain-id entangle_33133-1
entangled config keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0001aNGL\"/;" ~/.entangled/config/app.toml

sed -i -e "s|^persistent_peers *=.*|persistent_peers = \"$peers\"|" $HOME/.entangled/config/config.toml

(OPTIONAL) Set up pruning

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

(OPTIONAL) Set up indexer

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

(OPTIONAL) Enable/Disable Snapshots

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

Create a service file

tee /etc/systemd/system/entangled.service > /dev/null <<EOF

After=network-online.target

[Service]

systemctl daemon-reload
systemctl enable entangled
systemctl restart entangled && journalctl -u entangled -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
