Calculating “Total Received” and Balance by Address: A Step-by-Step Guide
As a cryptocurrency enthusiast, understanding the intricacies of the Ethereum blockchain can sometimes be difficult. One aspect that is often overlooked is calculating the total value of Ether (ETH) received and the balance for an individual address. In this article, we’ll walk you through how to do this step-by-step.
Understanding Ethereum Addresses
Before we dive into calculating “Total Received” and balance, let’s quickly review Ethereum addresses. An Ethereum address consists of a 40-character string, usually written in hexadecimal (0x…). These strings are unique, public, and can be used to identify an individual user or organization on the Ethereum network.
Total Received
The total value of Ether received is calculated by aggregating all transactions associated with an address. This requires knowing the blockchain’s transaction history, including:
- Transaction Hashes
: Each transaction is represented by a unique hash. By linking these hashes to their respective addresses and dates, we can reconstruct the entire transaction stream.
- Transaction Data: Transaction data contains information such as the sender and recipient addresses, the amount received or sent, gas fees, etc.
To calculate the total received, you need to:
- Retrieve the blockchain state
using a tool like
This will display the current state of your address, including all transactions.
- Extract Transaction Hashes: Take note of the transaction hashes for each relevant transaction associated with your address.
- Create a database of these transaction hashes and their corresponding addresses. You can use a simple text file or a lightweight database like SQLite.
- Join the transaction data to this hash database, using the "hash" fields as keys.
Example Use Case
For demonstration purposes, let's say we have an address with 10 transactions:
| Transaction Hash | Recipient Address | Amount Received |
| --- | --- | --- |
| a2...b3c4d5e6f7g8h9i | account1@domain.com | 10ETH |
To calculate the total received, we can link these hashes to their respective addresses and dates:
| Transaction Hash | SenderAddress | Recipient Address | Date |
| --- | --- | --- | --- |
| a2...b3c4d5e6f7g8h9i | account1@domain.com | account2@domain.com | 2022-01-01T00:00:00Z |
| a2...b3c4d5e6f7g8h9i | account1@domain.com | account3@domain.com | 2022-01-02T00:00:00Z |
Address Balancing
To calculate an individual's balance, you need to:
- Retrieve Blockchain State: Use a tool like to retrieve the current state of your address.
- Extract Sender Addresses and Amounts: Note the sender addresses and corresponding amounts for each transaction.
Example Use Case
Suppose we want to calculate our balance on January 5, 2022:
| Transaction Hash | SenderAddress | Amount Received |
| — | — | — |
| a2…b3c4d5e6f7g8h9i | account1@domain.com | 100ETH |
To calculate our balance, we can join the transaction data to this hash database, using the hash fields as keys:
- For January 5, 2022: a2…b3c4d5e6f7g8h9i
- Sender addresses and amounts for each transaction
Sample Code
Here is an example Python script that shows how to calculate the total received and balance using the information provided:
“`python
import sqlite3
Connect to the database
conn = sqlite3.connect(‘transaction_database.db’)
cursor = conn.cursor()
Retrieve the blockchain state
cursor.execute(“SELECT * FROM transactions WHERE address = ?”, (‘your_address’,))
transactions = cursor.
