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

Cryptocurrency Ethereum: Understanding Vin and Vout

When diving into the world of cryptocurrency transactions, one of the key aspects to understand is the concepts of VIN (Unique Identifier) ​​and VOUT (Value Output). These two components play a crucial role in ensuring the authenticity and integrity of transactions on the Ethereum blockchain.

In this article, we will explore how to identify the sender address and the recipient address from the content of a particular transaction.

Understanding VIN and VOUT

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

The VOUT values ​​are the output values ​​of these events. They indicate the amount of Ether (ETH) being sent from one address to another. For example, if you have two addresses: “0x1234567890ABCDEF” (initiator) and “0x234567890ABCDEF” (receiver), the VOUT value is calculated based on the specific event.

Determine sender address

To find the original address, we need to analyze the transaction data. Here is a step-by-step guide:

• Check transaction data: Check the first few lines of the transaction data (approximately 8-12 bytes). These usually contain information about the type of transaction (e.g. “transaction”, “payment”, etc.).

• Find VIN: The first 20 characters of the transaction information are the VIN value. If you can recognize this, it can help narrow down the possibilities.

• Specify transaction type: Most transactions have a specific type code (e.g. 1 for payment, 2 for transfer). This helps determine what type of event is being described.

Example: Ethereum Transaction Cancellation

Let’s say we are investigating a random event with a VIN value and a VOUT value:

VIN: 0x1234567890abcdef
VOUT: 1000 ETH

We can analyze the transaction data to determine the originating address. So:

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

• We know that the VOUT is 1000 ETH, which means a payment of 1,000 ether.

After analyzing this information, we can conclude that the event originated from an address, such as “0x234567890abef” (the recipient).

Identifying the recipient address

To find the recipient address:

• Search the event data: Analyze the first few lines of the event data.

• Check VIN and VOUT values: Make sure that the VIN value matches the expected pattern and the VOUT value matches the event type.

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

Conclusion

Understanding the VIN and VOUT values ​​is crucial when analyzing Ethereum transactions. By applying these concepts, you can decipher transaction data and more accurately identify the sender and receiver addresses.

In the next steps, focus on examining specific blockchain transactions to determine the VIN and VOUT values.
