* /blockchain
* /accounts
* /accounts/id/*:num*
* /accounts/*:account*
* /accounts/*:account*/balance
* /accounts/balance
* /eth
* /eth/blocks
* /eth/blocks/tx
### Creating an Ethereum Account
```bash
geth --datadir ./myNode1 new account
```
**Save Public Key**
#### Generate Genesis Block
```bash
puppeth
```
**Consensus Algorithm**: Cleque
#### Initialize Genesis Block
```bash
geth --datadir ./myNode1 init genesis_block.json
```
### Ethereum Node Setup
* scripts/config.sh
* Environment variables
* scripts/startU18.sh
* Start Ethereum node on Ubuntu
* scripts/startBSD.sh
* Start Ethereum node on FreeBSD
* scripts/GethFunc.js
* Use Ethereum management API's to perform operations on the blockchain.
#### Signing Address
```
export PUBLIC_KEY="0x..."
```
