Understanding the Vout Integer in GetRawTransaction Ethereum
When interacting with the Ethereum blockchain, you are likely working with transactions downloaded using getrawtransaction. As part of this process, each transaction is represented as a JSON object that contains an array of vin (verification information). Within this array, there is one element that stands out: the integer vout.
In this article, we will dive into what the integer vout represents in GetRawTransaction Ethereum and how to access it when working with transactions downloaded using this command.
vin array
The vin array is a key element of a Bitcoin transaction. It contains metadata about the input wallet that signed the transaction. The array has two elements: txid (transaction identifier) and vout.
- txid: This is the unique identifier of the transaction.
- vout: This is an integer representing the number of output addresses in the transaction.
Vout Integer
In the Ethereum blockchain, each vin.vout value corresponds to a specific output address. The integer vout represents the number of times a given output was used to send funds from the input wallet to the recipient.
When fetching a transaction using getrawtransaction, the resulting JSON object contains an array vin with two elements: txid and vout. In this array, each vout value is an integer representing the number of times a given output was used in a transaction. The highest vout value indicates the largest amount of funds sent to that recipient.
Example use case
To illustrate this concept, let’s consider a simple example:
Let’s assume we are fetching transactions using getrawtransaction and we want to examine the use of the input wallet to send funds to two different recipients (address 0x123…).
{
"txid": "...
}
In this case, the vout array would contain two elements:
- 0x1234567890abcdef: This is the first output address in the transaction. Let’s say it was used three times.
- 0x8765432109876543210: This is the second output address in the transaction. It was used twice.
To summarize, when working with Ethereum transactions retrieved using getrawtransaction, each vout integer in the vin array represents the number of times a specific output address was used to send funds from the input wallet to the recipient. Understanding this concept is essential to accurately analyzing Bitcoin transaction data.
