Installation guide

The following installation guide is for Linux Ubuntu machines.

Install git

1. sudo apt-get update
2. sudo apt-get upgrade
3. sudo apt-get install git

Install Python 3.9

1. sudo apt-get install python3.9

Set Python 3.9 as default Python version

1. Navigate to /usr/bin
2. Run ls -lrth /usr/bin/python* and check if /usr/bin/python3.9 is in the directory
3. Check for a Python symlink pointing to a specific Python version other than Python 3.9
4. Unlink python symlink using sudo unlink python
5. Link python using sudo ln -s /usr/bin/python3.9 python
6. Unlink python3 symlink using sudo unlink python3
7. Link python3 using sudo ln -s /usr/bin/python3.9 python3
8. Check default Python versions via python --versionand python3 --version. Both should show the same Python version Python 3.9.x

Install Curl

sudo apt-get install curl

Install Pip

sudo apt-get install python3-pip

Clone BeezX repository

1. Move to the directory you want to repository to be placed in (f.e. ~)
2. Run git clone https://github.com/onezerobinary/BeezX.git

Install BeezX requirements

1. Move to BeezX
2. Run pip install -r requirements/requirements.txt
3. Run pip install -r requirements/requirements.in

Set environment variables

1. Open ~/.bashrc
2. Add export BEEZ_NODE_KEY_PATH=path/to/privatekey.pem
3. Add export NODE_API_PORT=80
4. Add export FIRST_SERVER_IP=213.171.185.198
5. Add export P_2_P_PORT=5444
6. Relead bash by running source ~/.bashrc

Start BeezX Node in background

1. Navigate to BeezX
2. Run nohup python main.py &
3. Check if Node is running via curl yourip:5445/info you should see an output similar to `This is Beez Blockchain!. 🦾 🐝 🐝 🐝 🦾

Beez Node API Endpoints

Every Beez Blockchain node exposes a dedicated API on port 5445. The endpoints enable information requests as well as transaction requests. The following listing explains how to use the endpoints.

Information endpoints (GET)

/blockchain Returns all blocks of the blockchain in the following form:

{
	"blocks":[
		"blockCount": Int,           // Starting with 0
		"forger": String,            // PublicKey      
		"lastHash": String,          // Hash of last block
		"signature": String,         // Signature of forger
		"timestamp": Timestamp,
		"transactions": List[Transction]
	]
}

/accountstatemodel Returns information about the blockchain’s users public keys and their corresponding balances:

{
	"accounts": List[PublicKey],
	"balances": Dict[PublicKey, Int]
}

/blockindex Returns a combination of blocks and account information:

[
	{
		"header": 
			{
				"beezKeeper": Dict,
				"accountStateModel": {
					"accounts": List[PublicKey],
					"balances": Dict[PublicKey, Int]
				}
			}
		"transactions": List[Transaction],
		"blockCount": Int,           
		"forger": String,            
		"lastHash": String,          
		"signature": String,         
		"timestamp": Timestamp,
	}
]

Transaction endpoint (POST)

/transaction This endpoint is used to pass transactions to the blockchain:

{
	"id": UUID,                                                 // Transaction's id
	"senderPublicKey": PublicKey,
	"receiverPublicKey": PublicKey,
	"amount": Int,
	"type": Literal["EXCHANGE", "TRANSFER", "STAKE"],
	"timestamp": Timestamp,
	"signature": String,
	"py/object": "beez.transaction.transaction.Transaction"    // internal 
}

The endpoint returns:

{
	"message": "Received transaction"
}
