# Launch Blockchain using ignite command
Using environment varialbe you setup chain name ( and later chain ID).
```
export proj=iochain
export chainid=327
```
Following commands need to be execute on Coordinator/Master Node
```
gh repo create mytestlab123/${proj} --public --description 'IO Chain'
time ignite s chain github.com/mytestlab123/$proj
cd $proj
git add -A
git commit -am "init"
git remote add origin https://github.com/mytestlab123/$proj.git
git remote -v
git push -u origin master
time ignite n chain publish github.com/mytestlab123/${proj} --chain-id $proj
```
On Validator node, run following commands ( Here we have 3 different validators )
```
ignite n chain init ${chainid}
ignite n chain join ${chainid} --amount 95000000stake
```
On Coordinator node:
```
ignite n request list ${chainid}
ignite n request approve ${chainid} 3-4
ignite n request approve ${chainid} 5-6
ignite n request approve ${chainid} 6-7
ignite n request list ${chainid}
```
Once all validators are approve then *Launch the chain* on Coordinator node:
```
ignite n chain launch $chainid
# Check info details of the chain
ignite n chain show info $chainid
# Check the chain genesis file
ignite n chain show genesis $chainid
# Check all vesting and genesis accounts of the chain
ignite n chain show accounts $chainid
# Check all validators of the chain
ignite n chain show validators $chainid
# Check peers list of the chain
ignite n chain show peers $chainid
```
Once the chain is launched on Coordinator node then run following commands to join the blockchain network:
```
ignite n chain prepare $chainid
${proj}d start --home ${HOME}/spn/$chainid
```
