Coinbase Transaction Mystery: Understanding ROI
When a user interacts with their crypto wallet on a platform like Coinbase, they can initiate transactions to send funds to other users or receive coins from others. However, when it comes to receiving a large number of coins, some users may be surprised to see two output addresses in the transaction details. One of these output addresses is labeled “OP_RETURN,” which has caused confusion among many crypto enthusiasts.
In this article, we will delve into the world of ROI and explain why a miner would choose to include OP_RETURN in a Coinbase transaction.
What is ROI?
The term “ROI” comes from the open-source Ethereum blockchain software. ROI is basically a special type of transaction that allows the creation of multiple output addresses with different balances, known as “outputs.” These outputs can be used to send funds to different recipients without incurring unnecessary gas fees.
Why would a miner include OP_RETURN in a Coinbase transaction?
Ethereum miners use complex algorithms to validate transactions and ensure the integrity of the blockchain. When a user initiates a transaction, miners must create multiple output addresses with different balances. These output addresses are then broadcast to the network for verification.
In the case of a Coinbase transaction, OP_RETURN is used to create multiple outputs that can be used to send funds in different ways. Here’s how it works:
- Coinbase receives initial payment: User initiates a Coinbase transaction using their wallet.
- Miner creates output addresses for OP_RETURN: Ethereum miners create two separate output addresses using the OP return algorithm (more on this below).
- Miner includes OP_RETURN in the transaction: The miner adds these two output addresses to the Coinbase transaction, creating multiple outputs that can be used to send funds.
- Transaction is broadcast and verified by miners
: The transaction is broadcast to the network for verification by other nodes.
Why use OP_RETURN?
There are several reasons why a miner would choose to include OP_RETURN in their transaction:
- Reduce gas fees: By using OP_RETURN, miners can create multiple outputs with different balances, which helps reduce the overall gas fee required for the transaction.
- Increase network efficiency: OP_RETURN allows users to receive coins from multiple sources without having to verify each individual output address.
- Maximize Miner Profit: Miners who use op returns may have an advantage over those who don’t, by undertaking more transactions and increasing their chances of receiving a larger payment.
Coinbase Transaction Example
Let’s take a closer look at the example provided: “I’m looking at this Coinbase transaction. I don’t understand why there are two outputs, and why is one of them labeled OP_RETURN.”
In this case, the Coinbase transaction could have been initiated by a user who wants to receive funds from multiple sources (e.g. a friend’s wallet) without having to verify each individual output address.
The label “OP_RETURN” would indicate that the sender created two separate output addresses using the op return algorithm. These outputs could be used to send coins to different recipients, which could have been done by simply sending a single transaction or multiple transactions instead of creating additional output addresses.
Conclusion
To sum up, op returns play a crucial role in the Ethereum transaction process when it comes to Coinbase transactions. Using op returns, miners can create multiple output addresses with different balances, reducing gas fees and increasing network efficiency.
