“Total received” calculation and balance by address: a step-by-step guide

As an enthusiast of cryptocurrency, understanding the complexities of the Ethereum blockchain can sometimes be overlying. An aspect that is neglected is the calculation of the total value of the ether received (ETH) and the balance for an individual address. In this article, we will break down how to do it step by step.

Understanding of the Ethereum*guidelines

Before immersing ourselves in the calculation of the “total received” and balance, we quickly examine the Ethereum addresses. An Ethereum address consists of a string of 40 characters, typically written in hexadecimal (0x …). These strings are unique, public and can be used to identify a single user or organization on the Ethereum network.

Total received

The total value of the ether received is calculated by aggregating all transactions associated with an address. This requires knowledge of the history of blockchain transactions, including:

Transaction hash : Each transaction is represented by a unique hash. By connecting the thesis hash to their respective addresses and dates, we can reconstruct the entire flow of transactions.

Transaction data : transactions data contain information such as sender and receiver addresses, amount received or envoy, gas commissions, etc.

To calculate the total received, you will have to:

Take the blockchain state using a tool like & chainid = 1. This will display the current state of your address, including all transactions.

Hash of extracted transaction : Take note of the transaction hash for each relevant transaction associated with your address.

Create a database or these transaction hash and their corresponding addresses. You can use a simple text file or a light database like SQLite.

Join the data of the transaction to this database hash, using the fields hash as keys.

Example of use of the case

For demonstration purposes, suppose that we have an address with 10 transactions:

| Hash transaction | Address of the receiver | Amount received |

| — | — | — |

| A2 … B3C4D5E6F7G8H9I | account1@domain.com | 10 Eth |

To calculate the total recurrence, we can connect these hateh to their respective addresses and dates:

| — | — | — | — |

Balance of the address

To calculate the balance of an individual, you will have to:

Take the Blockchain State : use an instrument such as & chain = 1 to recover the current state of your address.




 Extract addresses and amounts of the sender 

: Take note of the sender's addresses and the corresponding amounts for each transaction.


 Example of use of the case 

Suppose we want to calculate our balance on January 5, 2022:

| Hash transaction | Sender address | Amount received |

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

| A2 ... B3C4D5E6F7G8H9I | account1@domain.com | 100 Eth |

To calculate our balance, we can combine transactions data to this database hash, using the fieldshashas keys:




For January 5, 2022: A2 ... B3C4D5E6F7G8H9I



Addresses and sender amounts for each transaction


 Example of code 

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

` Python

import sqlite3

Connect to the database

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

Cursor = Conn.Cursor ()

Take Blockchain State

Cursor.execute (“Select * from transactions where address =?”, (‘Your_address’,)))

Transactions = cursor.
