Calculating Total Received and Balance by Address: Step by Step

As a cryptocurrency enthusiast, understanding the intricacies of the Ethereum blockchain can be overwhelming at times. One often overlooked aspect is calculating the total value and balance of Ether (ETH) received for an individual address. In this article, we’ll break down 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 individual users or entities on the Ethereum network.

Total Received

The total value of Ether received is calculated by summing all transactions associated with that address. This requires knowledge of the blockchain’s transaction history, including:

• Transaction hashes

  

  : Each transaction is represented by a unique hash. These hashes can be linked to their corresponding addresses and dates to reconstruct the entire transaction flow.

• Transaction data: Transaction data includes information such as the sender and receiver addresses, the amount received or sent, gas fees, etc.

To calculate the total amount received, you will need to:

• Get the blockchain status using a tool such as This will display the current status of your address, including all transactions.

• Extract transaction hashes: Record transaction hashes for each transaction associated with your address.

• Create a database of these transaction hashes and their corresponding addresses. You can use a plain 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 assume we have an address with 10 transactions:

| Transaction hash | Buyer address | Amount received |

| --- | --- | --- |

| a2...b3c4d5e6f7g8h9i | account1@domain.com | 10 ETH |

To calculate the amount received, we can join these hashes with the corresponding addresses and dates:

| Transaction hash | Sender address | Buyer 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 |

Balancing the address

To calculate a person's balance, you will need the following:

• Get the blockchain status: Use a tool like to get the current status of the address.

• Extract sender addresses and amounts

  : For each transaction, note the sender address and the amounts associated with them.

Example Use Case

Let’s say we want to calculate our balance as of January 5, 2022:

| Transaction Hash | Sender Address | Amount Received |

| — | — | — |

| a2…b3c4d5e6f7g8h9i | account1@domain.com | 100 ETH |

To calculate our balance, we can connect the transaction data to this hash database, using the hash' fields as keys:

• On January 5, 2022: a2...b3c4d5e6f7g8h9i

• Sender addresses and amounts for each transaction

Example code

Here is an example Python script that shows how to calculate the total amount received and the balance based on the information provided:

“ python

import sqlite3

Connect to the database

conn = sqlite3.connect(‘transaction_database.db’)

cursor = conn.cursor()

Get blockchain state

cursor.execute(“SELECT * FROM transactions WHERE address = ?”, (‘your_address’,))

transactions = cursor.
