# Node

## Deploy Chain Services

## Preparation

```
apt-get install gcc
wget https://go.dev/dl/go1.21.6.linux-amd64.tar.gz
tar zvxf go1.21.6.linux-amd64.tar.gz
mkdir -p /data/go
mv go /data/go/go1.21.6
vim /etc/profile
//"Add at the end"
export GOROOT=/data/go/go1.21.6
export GOPATH=/data/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
//"Save and close"
source /etc/profile
go version
```

If the Go version number can be printed out in the end, it indicates that the installation was successful.\
To ensure the node participates in the network, please open port 26656.

## Download Code

## Initialization

#### Initialize the node. Replace `MONIKER` and `HOMEDIR` with the desired nickname and path.

```
mttd init MONIKER --chain-id mtt_6880-1 --home HOMEDIR --overwrite
```

Download chain data.

```
wget https://snapshot.mtt.network/mtt-mainnet-snapshot.tar.gz
tar -xzvf mtt-mainnet-snapshot.tar.gz
```

Copy chain data.

```
cp -r mtt-mainnet-snapshot/config/genesis.json HOMEDIR/config
cp -r mtt-mainnet-snapshot/data HOMEDIR/
```

Modify the p2p configuration.

```
vim HOMEDIR/config/config.toml

persistent_peers = "1d8321f65e3d269bc4af1d94d5b92eca3fd8455a@101.44.201.39:26656,11a1b3b3c36da845930258e367c55e859e93f0aa@159.138.34.3:26656,1315c9aeca9287c166be968fae79ddf7ec1482cc@8.219.219.202:26656,ac40cf5500d5938b4d9fec63cdfc116c5365f2b0@54.251.208.79:26656"

```

Modify the contents of the following fields in the config.

```
timeout_propose = "1.8s"
timeout_propose_delta = "500ms"
timeout_prevote = "600ms"
timeout_prevote_delta = "500ms"
timeout_precommit = "600ms"
timeout_precommit_delta = "500ms"
timeout_commit = "3s"
```
