Ethereum: Any single transaction has vin and vout values. How can I tell the address of the originator and receiver?

Deciphering Ethereum Transactions: Understanding Vin and Vout Values

As you delve deeper into the world of cryptocurrency transactions, one crucial aspect to grasp is the concept of VIN (Unique Identifier) ​​and VOUT (Value Output) values. These two components play a vital role in verifying the authenticity and integrity of transactions on the Ethereum blockchain.

In this article, we’ll explore how to identify the originator address and receiver address from the contents of a specific transaction.

Understanding VIN and VOUT Values

A VIN is a unique identifier assigned to each block or transaction on the Ethereum network. It’s essentially a digital fingerprint that helps ensure the transaction has not been tampered with during its journey to the final destination. Each block contains multiple transactions, and each one has a corresponding VIN value.

VOUT values ​​are the output values ​​of these transactions. They represent the amount of Ether (ETH) being sent from one address to another. For example, if you have two addresses: 0x1234567890ABCDEF (originator) and 0x234567890ABCDEF (receiver), the VOUT value would be calculated based on the specific transaction.

Identifying the Originator Address

To find the originator address, we need to analyze the transaction data. Here’s a step-by-step guide:

  • Check the Transaction Data: Examine the first few lines of the transaction data (around 8-12 bytes). These typically contain information about the type of transaction (e.g., “transaction”, “fee”, etc.).

  • Look for VIN

    : The first 20 characters in the transaction data will be the VIN value. If you can identify this, it can help narrow down the possibilities.

  • Identify the Transaction Type: Most transactions have a specific type code (e.g., 1 – payment, 2 – transfer). This helps determine which type of transaction is being described.

Example: Decoding an Ethereum Transaction

Suppose we’re examining a random transaction with the following VIN value and VOUT value:

VIN : 0x1234567890abcdef

VOUT: 1000 ETH

We can break down the transaction data to identify the originator address. Here’s how:

  • The first 20 characters (0x1234567890abcdef) match the VIN pattern.

  • We know that VOUT is 1000 ETH, which indicates a payment of 1,000 Ether.

By analyzing this information, we can infer that the transaction originated from an address such as 0x234567890abef (receiver).

Identifying the Receiver Address

To find the receiver address, follow these steps:

  • Look for Transaction Data: Analyze the first few lines of the transaction data.

  • Check for VIN and VOUT Values: Verify that the VIN value matches the expected pattern and that the VOUT value aligns with the transaction type.

In our example above, we can identify the receiver address as 0x234567890abef based on the VIN value (0x1234567890abcdef) and the VOUT value (1000 ETH).

Conclusion

Understanding VIN and VOUT values ​​is crucial to analyzing Ethereum transactions. By applying these concepts, you’ll be able to decode transaction data and identify the originator and receiver addresses more accurately.

In your next steps, focus on examining specific transactions in the blockchain to practice identifying VIN and VOUT values.
