Validator / Node Setup

Hardware Requirements​

The minimum recommended specs for running Mycel Node as follows:

Node TypeCPU Cores(s)MemorySSD
Validator432GB1TB+
Full Node216GB1TB
Light Node24GB

Install Mycel Binary​

To install the latest version of the Mycel binary use the following command.

curl https://get.ignite.com/mycel-domain/mycel@latest! | sudo bash

Or specific version like v0.1.2

curl https://get.ignite.com/mycel-domain/mycel@v0.1.2! | sudo bash

Configuration​

Setup enviroment values

SEED_RPC={SEED_RPC_URL_HERE}
SEED_P2P={SEED_P2P_URL_HERE}
GENESIS_JSON={GENESIS_JSON_URL_HERE}
MONIKER={MONIKER_NAME_HERE}
CHAIN_ID={CHAIN_ID_HERE}

Initialize configuration files with

mycel init $MONIKER --chain-id $CHAIN_ID

Download genesis.json.

curl -L $GENESIS_JSON -o $HOME/.mycel/config/genesis.json
SEED_NODE_ID=$(curl $SEED_RPC/status | jq -r '.result.node_info.id')
sed -i "s/seeds = \"\"/seeds = \"${SEED_NODE_ID}@${SEED_P2P}\"/g" $HOME/.mycel/config/config.toml
sed -i "s/persistent_peers = \"\"/persistent_peers = \"${SEED_NODE_ID}@${SEED_P2P}\"/g" $HOME/.mycel/config/config.toml

Setup statesync (Optional)​

Get the latest height from seed.

SNAPSHOT_INTERVAL=500
LATEST_HEIGHT=$(curl -s $SEED_RPC/block | jq -r .result.block.header.height)
BLOCK_HEIGHT=$((LATEST_HEIGHT - SNAPSHOT_INTERVAL))
TRUST_HASH=$(curl -s "$SEED_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

Update statesync configuration.

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

Running Node​

Manually​

mycel start

Use myceld [command] --help for more information about a command.

Using systemd​

sudo vim /etc/systemd/system/mycel.service
[Unit]
Description=Mycel Daemon
After=network-online.target

[Service]
User=root
ExecStart={PATH_TO_MYCEL_BINARY} start --home {PATH_TO_CONFIG_DIR}
Restart=always
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

Enable service.

sudo systemctl daemon-reload
sudo systemctl enable mycel

Become a Validator​

Add your account to keyring

mycel keys add {ACCOUNT_NAME} --keyring-backend {KEYRING_NAME}

Register a Validator

mycel tx staking create-validator \
    --amount="100000umycel" \
    --pubkey=$(mycel tendermint show-validator) \
    --moniker=$MONIKER \
    --commission-rate="0.01" \
    --commission-max-rate="0.1" \
    --commission-max-change-rate="0.01" \
