Blockchain is a distributed ledger technology that serves as a system for recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.


Blockchain technology has changed the way we think about digital transactions and data storage. 


As this technology continues to evolve and gain widespread adoption, the need for understanding and analyzing blockchain data has become increasingly important. This is where blockchain analytics comes into play.


What is Blockchain Analytics?

Blockchain analytics refers to the process of examining, interpreting, and deriving insights from blockchain data. It involves scrutinizing blockchain transactions, addresses, smart contracts, and other on-chain activities to uncover patterns, trends, and valuable information. 


In today's digital economy, blockchain analytics has become a crucial tool for businesses, investors, researchers, and regulators alike.


What are Blockchain Transactions?

Before diving deeper into blockchain analytics, it's essential to understand what blockchain transactions are and how they work. 

 An image showing how blockchain transactions work.

A blockchain transaction is a transfer of value between two addresses on a blockchain network. These transactions are the building blocks of blockchain technology and form the basis for all activities on the network.


Here's how blockchain transactions typically work:


1. Initiation: A user initiates a transaction by specifying the recipient's address and the amount to be sent.

2. Broadcast: The transaction is broadcast to the network and placed in a pool of unconfirmed transactions.

3. Verification: Network nodes (miners or validators) verify the transaction's validity.

4. Inclusion in a block: Once verified, the transaction is included in a new block.

5. Confirmation: The block is added to the blockchain, confirming the transaction.

6. Finality: After several more blocks are added, the transaction is considered final and irreversible.


The transparency of blockchain transactions is one of the key features that make blockchain technology so powerful. Every transaction is recorded on a public ledger, allowing anyone to view and verify the transaction history.


What is the Significance of Blockchain Analytics?

Blockchain analytics plays a crucial role in extracting value from the vast amount of data stored on blockchain networks. Its significance can be understood through several key aspects:


Blockchain Analytics for Transparency

  • Enhanced visibility: Blockchain analytics provides a clear view of all transactions, helping to track the flow of assets and identify patterns.

  • Auditability: It enables thorough audits of transactions, ensuring compliance and detecting anomalies.

  • Trust building: By providing transparent insights, blockchain analytics helps build trust among users and stakeholders.


Fraud Detection Using Blockchain Analytics

Methodologies in Blockchain Analytics

Address clustering is a technique used to group multiple blockchain addresses that are likely controlled by the same entity. This method is crucial for understanding the true nature of transactions and entity behaviors on the blockchain.


Here's how it works:

1. Heuristic analysis: Using common-sense rules to identify related addresses. For example, addresses that frequently transact together might belong to the same entity.

2. Co-spend analysis: Identifying addresses that are used as inputs in the same transaction, suggesting they're controlled by the same entity.

3. Behavioral patterns: Analyzing transaction patterns and timings to identify similarities among addresses.


Network Analysis in Blockchain Transactions

Network analysis in blockchain involves studying the relationships and interactions between different addresses or entities on the blockchain. This methodology helps in understanding the structure and dynamics of the blockchain ecosystem.


Key aspects include:

1. Graph theory: Representing blockchain data as a network graph, where addresses are nodes and transactions are edges.

2. Centrality measures: Identifying important or influential addresses in the network.

3. Community detection: Finding clusters of closely connected addresses that might represent organizations or groups.

4. Flow analysis: Tracking the movement of funds through the network to understand transaction patterns and asset distribution.


How to Query the Blockchain

Querying the blockchain is a fundamental skill in blockchain analytics. Here are some methods and tools you can use:

1. Block explorers: Websites like Etherscan (for Ethereum) or Blockchain.info (for Bitcoin) allow basic querying of transactions, addresses, and blocks.

2. API services: Many blockchain networks offer APIs that allow programmatic access to blockchain data.

3. Node running: Running a full node of a blockchain network gives you direct access to all blockchain data, allowing for custom queries.


Using Ethereum ETL for Blockchain Data Extraction

Ethereum ETL (Extract, Transform, Load) is an open-source tool that allows you to extract data from the Ethereum blockchain and export it into more easily queryable formats like CSV or JSON. Here's a basic workflow:

  1. Install Ethereum ETL

  2. Choose the data you want to extract (e.g., transactions, blocks, token transfers)

  3. Run the extraction command

  4. Process and analyze the extracted data


Google BigQuery for Blockchain Data Analysis

Google BigQuery hosts public datasets for several major blockchains, allowing for powerful SQL-based analysis. Here's how you can use it:

  1. Access Google Cloud Platform and navigate to BigQuery

  2. Select the blockchain dataset you want to analyze (e.g., bigquery-public-data.crypto_ethereum)

  3. Write and run SQL queries to analyze the data

  1. WHERE: Filters the results based on a condition

SELECT * FROM transactions WHERE value > 1000000;
  1. GROUP BY: Groups rows that have the same values.

SELECT from_address, COUNT(*) as transaction_count 
FROM transactions 
GROUP BY from_address;
  1. ORDER BY: Sorts the result set in ascending or descending order

SELECT * FROM blocks 
ORDER BY timestamp DESC 
LIMIT 10;
  1. JOIN: Combines rows from two or more tables based on a related column

SELECT t.hash, t.value, b.timestamp 
FROM transactions t
JOIN blocks b ON t.block_number = b.number;

These basic commands will allow you to start querying blockchain data effectively.


How to Build a Simple Dashboard

SELECT
  collection,
  COUNT(*) AS number_of_transactions,
  SUM(amount_usd) AS total_transaction_volume,
  SUM(platform_fee_amount_usd) AS total_platform_fees,
  SUM(royalty_fee_amount_usd) AS total_royalties
FROM nft.trades
WHERE nft_contract_address = 0x062E691c2054dE82F28008a8CCC6d7A1c8ce060D --(PudgyPresent)
GROUP BY collection 

3. Run the query and view the results.

4. Create a visualization: Click on "New Visualization", choose a chart type (e.g., bar chart), and configure it to display the data.

5. Add the visualization to your dashboard.

6. Repeat the process with other queries to build a comprehensive NFT analytics dashboard.

This example demonstrates how you can use SQL queries to extract meaningful insights from blockchain data and present them visually.
