How to connect into Private Ethereum Blockchain (eBloc)

Geth

Preinstallations

Installation Instructions for Mac

git clone https://github.com/ethereum/go-ethereum
brew install go
cd go-ethereum
make geth

Installation Instructions for Linux

Go-installation (go-ethereum requires go version 1.7+.):

tar -zxvf  go1.7.1.linux-amd64.tar.gz -C /usr/local/
sudo tar -zxvf  go1.7.1.linux-amd64.tar.gz -C /usr/local/
export PATH=$PATH:/usr/local/go/bin
cp  /usr/local/go/src/go /usr/bin/go

Geth Installation

sudo apt-get install git
git clone https://github.com/ethereum/go-ethereum
sudo apt-get install -y build-essential libgmp3-dev golang
cd go-ethereum/
git pull
make geth

---

eBloc Setup on Linux and macOS

After go-ethereum is installed copy geth into/usr/local/bin:

[~] ls go-ethereum/build/bin
geth
[~] sudo cp build/bin/geth /usr/local/bin/
[~] which geth
/usr/local/bin/geth

Now when you just type geth, it should work.

eBloc Setup on Linux and macOS

git clone https://github.com/ebloc/MyEthereumEbloc_geth.git
cd MyEthereumEbloc_geth
ebloc_path="$PWD";
sudo geth --datadir="$ebloc_path" account new

Your new account is locked with a password. Please give a password. Do not forget this password. Please enter a difficult passphrase for your account.

[~] sudo geth --datadir="$ebloc_path" init CustomGenesis.json

Welcome to the Geth JavaScript console!

instance: Geth/v1.7.0-stable-6c6c7b2a/darwin-amd64/go1.9
 modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0

> 

[geth]> net
{
listening: true,
peerCount: 0,
version: "23422",
getListening: function(callback),
getPeerCount: function(callback),
getVersion: function(callback)
}

peerCount should be 1, after running following command inside geth.

admin.addPeer("enode://4d331051d8fb471c87a9351b36ffb72bf445a9337727d229e03c668f99897264bf11e1b897b1561f5889825e2211b06858139fa469fdf73c64d43a567ea72479@193.140.197.95:3000");

[geth]> admin.addPeer("enode://4d331051d8fb471c87a9351b36ffb72bf445a9337727d229e03c668f99897264bf11e1b897b1561f5889825e2211b06858139fa469fdf73c64d43a567ea72479@193.140.197.95:3000");
[geth]> net
{
listening: true,
peerCount: 1,
version: "23422",
getListening: function(callback),
getPeerCount: function(callback),
getVersion: function(callback)
}

Now open a new terminal and open a client:

[~] sudo geth --datadir "$ebloc_path" attach ipc:$ebloc_path/geth.ipc console
Welcome to the Geth JavaScript console!

instance: Geth/v1.5.7-stable-da2a22c3/darwin/go1.7.4
modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0

[geth]> net
{
listening: true,
peerCount: 1,
version: "23422",
getListening: function(callback),
getPeerCount: function(callback),
getVersion: function(callback)
}

To check your account using geth:

[geth]> primary = eth.accounts[0]
"0x42760ddded01a938666a34444e478b710d43cb5a"]
[geth] web3.fromWei(web3.eth.getBalance(primary));
0                             //Your balance will increase when you mine.
[geth]> web3.fromWei(web3.eth.getBalance("0xda1e61e853bb8d63b1426295f59cb45a34425b63"));
46221.847517764296887374      //This is the some account active on the Blockchain. If you are connected into eBloc, you should see it.

If you would like to start your miner, just type following inside geth: miner.start() .To stop mining: miner.stop()

You could also decide how many CPU you would like to invest to mine. For example, following line will add additional 1 CPU. miner.start(1)

Helpful Script

Please update ebloc_path variable on server.sh and client.sh files with path of MyEthereumEbloc folder.

To run: Let's make scripts executable: sudo chmod +x server.sh client.sh

You can now run the bash: sudo ./server.sh

Now open a new terminal and run: ./client.sh. net should return minimum 1.
