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.

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"
