BORA Lagoon Network

This document is a guide for interconnecting the Ethernet network(A) and Side Chain(B) configured for the BORA Lagoon Network. For smooth testing, the BORA Lagoon is configured internally on the Ethernet network, and it will be replaced by Ethereum mainnet in the subsequent full version.

Configuring the BORA Lagoon Network

The installation below is an example of configuring in Linux CentOS 7 and macOS environment.

1Download Install script

Download the script prepared for installation using git.

Cent OS 

sudo su -

#Install git if your machine is not installed git.
yum install git
yum update -y nss curl libcurl

git clone https://github.com/boraecosystem/bora-tools.git
cd ./bora-tools/boraadmin/install

Mac OS

cd ~/
git clone https://github.com/boraecosystem/bora-tools.git

cd ~/bora-tools/boraadmin/install

2Install System libraries

Update system libraries for source compilation.

Cent OS 

sh 10.yuminstall.sh

Mac OS

sh 10.mac_install.sh

3Install golang-go package

Build the Go environment to compile the blockchain core source.

Cent OS 

sh 20.golang.sh

Mac OS

sh 20.mac_golang.sh

4Install go-bora

Download and compile the blockchain core source.

Cent OS 

sh 30.go-bora.sh

Mac OS

sh 30.mac_go-bora.sh

5Connect to testnet-ethernode

Connect to the blockchain node using the provided script. Port is 8545.

Cent OS 

# Port number for connecting ether node: 8545
sh 40.setup8545_BORAToken.sh

Mac OS

# Port number for connecting ether node: 8545
sh 40.mac_setup8545_BORAToken.sh

6Connect to testnet-chainnode (Port:8501~8509)

Also connecting the BORA chain nodes the same as the procedure above.

Cent OS 

# Port number for connecting chain node: 8501-8509
sh 41.setup8501_BORAShell.sh
sh 41.setup8502_BORAShell.sh
sh 41.setup8503_BORAShell.sh
sh 41.setup8504_BORAShell.sh
sh 41.setup8505_BORAShell.sh
sh 41.setup8506_BORAShell.sh
sh 41.setup8507_BORAShell.sh
sh 41.setup8508_BORAShell.sh
sh 41.setup8509_BORAShell.sh

Mac OS

# Port number for connecting chain node: 8501-8509
sh 41.mac_setup8501_BORAShell.sh
sh 41.mac_setup8502_BORAShell.sh
sh 41.mac_setup8503_BORAShell.sh
sh 41.mac_setup8504_BORAShell.sh
sh 41.mac_setup8505_BORAShell.sh
sh 41.mac_setup8506_BORAShell.sh
sh 41.mac_setup8507_BORAShell.sh
sh 41.mac_setup8508_BORAShell.sh
sh 41.mac_setup8509_BORAShell.sh

8Test for connectivity to node using geth

You can connect to and view each node by using geth attach command or 2.conn_geth.sh.

Cent OS 

sh 50.node_monitor.sh

Mac OS

sh 50.mac_node_monitor.sh

Cent OS 

geth attach ~/bora-tools/boraadmin/NODE/8545/geth.ipc

Mac OS

geth attach ~/bora-tools/boraadmin/NODE/8545/geth.ipc
You can view block number and block information by using the following command.
> eth.blockNumber
88066
> eth.getBlock("latest")
