The article aims to demonstrate how to use GPT Neo, the Hugging Face Transformers module, Python programming language, Web3.py library, and a blockchain database to create a conversational interface that allows users to interact with the blockchain network more user-friendly and intuitively. By the end of the article, readers should clearly understand how to use these tools to build a chatbot that can retrieve and display data from a blockchain database based on user queries.
This article was published as a part of the Data Science Blogathon.
Before we begin, you will need to install the following packages:
You can install these packages using pip, the Python package manager:
pip install web3 transformers
Before we can build our chatbot, we need to connect to the Ethereum blockchain using Web3.py. To do so, we will be using the Web3.py library. First, we will import the necessary modules and initialize a connection to the blockchain:
from web3 import Web3
# Initializing a connection to the blockchain
w3 = Web3(Web3.HTTPProvider('https://mainnet.infura.io/v3/YOUR-PROJECT-ID'))
# Checking if the connection is successful
if w3.isConnected():
print('Connected to the Ethereum network')
else:
print('Connection to the Ethereum network failed')
With an Infura project ID, we connect to the Ethereum main net in this illustration. You can provide your own Infura project ID or a local node address in place of the placeholder YOUR-PROJECT-ID.
After establishing a link with the blockchain, we can use the Web3.py library to query data from the blockchain. For instance, we can get the most recent block number:
# Retrieving the latest block number
latest_block = w3.eth.blockNumber
print(f'The latest block number is {latest_block}')
This will output the latest block number to the console.
We will use the GPT Neo model from Hugging Face Transformers to provide conversational access to the blockchain data. First, we will import the necessary modules and initialize the model:
from transformers import pipeline
# Initializing the GPT Neo pipeline
chatbot = pipeline('text-generation', model='EleutherAI/gpt-neo-1.3B')
In this example, we use the 1.3B variant of the GPT-Neo model from EleutherAI. You can replace this with a different model if you prefer.
We can now leverage our chatbot and blockchain connection to offer conversational access to blockchain data. This is an illustration of a dialogue:
# Defining a function to handle user input
def handle_input(input_text):
# Generating a response using GPT Neo model
response = chatbot(input_text)[0]['generated_text']
# Extracting the latest block number from the blockchain
latest_block = w3.eth.blockNumber
# If user asks for the latest block number, return it
if 'latest block number' in input_text.lower():
return f'The latest block number is {latest_block}.'
# If user asks for the block hash of a specific block, return it
if 'block hash' in input_text.lower():
block_number = int(input_text.split()[-1])
block_hash = w3.eth.getBlock(block_number)['hash'].hex()
return f'The hash of block {block_number} is {block_hash}.'
# Otherwise, return the GPT Neo response
return response
# Starting a conversation with the user
while True:
# Prompting the user for input
user_input = input('You: ')
# Handling the user input
response = handle_input(user_input)
# Printing the response
print(f'Chatbot: {response}')
This will continuously prompt the user for input, generate a response using GPT Neo, and return the answer to the user. If the user asks for the latest block number or the hash of a specific block, the function handle_input() will query the blockchain using Web3.py and return the corresponding information. Otherwise, GPT Neo will generate a response based on the user input.
Overall, conversational interfaces provide a promising solution for accessing blockchain databases, offering a more accessible, convenient, and secure way to interact with blockchain technology.

Overall, while conversational interfaces can offer some benefits in accessing blockchain databases, they may not be suitable for all use cases. Considering the advantages and restrictions of conversational interfaces before implementing them in a blockchain application is essential.
In summary, the concepts we went through in this article include the following:
We can design more approachable and accessible interfaces for interacting with complex data. We can achieve this by combining the strength of blockchain technology and conversational AI. This method might be used in several use cases, including supply chain management and finance, to assure openness, correctness, and security.
Therefore with the ongoing development of blockchain and conversational AI, we can expect to see even more innovative and user-friendly solutions emerge. Overall, integrating these technologies can unlock new possibilities for creating more accessible and secure interfaces for interacting with complex data.
