Understanding the Vout Integer in Ethereum’s GetRawTransaction
When interacting with Ethereum’s blockchain, you’re likely working with transactions fetched using getrawtransaction. As part of this process, each transaction is represented as a JSON object, which includes a vin (verify info) array. Within this array, one element stands out: the vout integer.
In this article, we’ll delve into what the vout integer represents in Ethereum’s GetRawTransaction and how to access it when working with transactions fetched using this command.
The vin Array
The vin array is a key component of a Bitcoin transaction. It contains metadata about the input wallet that signed the transaction. The array has two elements: txid (transaction ID) and vout.
- txid: This is the unique identifier for the transaction.
- vout: This is an integer representing the number of output addresses in the transaction.
The Integer vout
In Ethereum’s blockchain, each vin.vout value corresponds to a specific output address. The vout integer represents the number of times this particular output was used to send funds from the input wallet to the recipient.
When fetching transactions using getrawtransaction, the resulting JSON object contains a vin array with two elements: txid and vout. Within this array, each vout value is an integer representing how many times that specific output was used in the 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:
Suppose we’re fetching transactions using getrawtransaction and want to examine the usage of an input wallet to send funds to two different recipients (address 0x123…).
{
"do": "...
}
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.
In summary, when working with Ethereum transactions fetched using getrawtransaction, each vout integer in the vin array represents how many times a specific output address was used to send funds from an input wallet to a recipient. Understanding this concept is essential for accurately parsing and analyzing Bitcoin transaction data.
