Double output of Double Connice Transaction: The complexity of Ethereum with Deamplete
As a passionate blockchain, you probably know the concept of Ethereum Ethereum transaction. However, you have ever wondered why there are two separate transactions when sending coins to the same address? In this article, we deepen in the interior functioning of the eThereum transaction processing and examine what is happening behind the scenes.
Basics: transaction outputs
In the blockchain network, such as Ethereum, each transaction consists of a sender, recipient, quantity and other metadata. The unique identifier for each transaction output is called “hash”, which serves as a reference to the initial transaction. In most cases, you will only see the hash associated with a single output from the transaction.
Phenomenon of double transaction output
When you send coins to Ethereum, what happens, the consignor and the recipient will receive two separate transactions: one for the payment itself (“entry” transaction) and the other to the output of the transaction itself (“output” transaction). It may seem contraintuitive at first glance, but it is the result of the Ethereum design.
To understand why this happens, let’s examine how Ethereum manages more transactions in one block. Once the new block is created, it contains a list of the received transactions that are checked by the network and added to the blockchain. Each transaction has two entrances (from different wallets) and output (payment). By default, these outputs are included in one transaction.
Output transaction format
In the Ethereum transaction format, each entrance is associated with a unique hash and the recipient receives the amount of payment and the relevant hash transactions. The transaction output itself contains two values: the amount of payment and the other hash concerning the initial transaction.
Here’s an example of what it might look like:
`
{
"Transaction_id": "1234567890abcDef",
“Records”: [
{
"Z": "jfwe8thcaqryx9C43DXSGYOPL9ZS62D",
“Sum”: “10.00 ETH”
}
] ,,
“Outputs”: [
{
“Sum”: “5.00 ETH”,
"To": "0x1234567890abcDef"
},
{
"Payments_Hash": "Hash1234567890abcDef",
"TX_Hash": "Transaction_id"
}
]
}
`
Why two outputs?
Now that we understand how the transaction output format works, it is clear why there are two exits when sending coins to Ethereum. The second output is used as a reference to the recipient to verify the initial transaction and to ensure its validity. This allows the recipient to check the amount of the payment and confirm that the transaction has been successful.
Conclusion
In conclusion, the phenomenon of the output of the double transaction in the Ethereum blockchain may seem confused at first glance, but it is an essential part of the network functionality. Understanding how the transactions are controlled and included together, we receive a perspective why there are two exits when we send coins to the address. As an Ethereum user, it is necessary to understand this concept to fully appreciate your favorite blockchain.
Update:
As for the specific transaction you mentioned at blockchain.com:
- The first part of the transaction (from JFWE8THCAQQRYX99C43DXSGYOPL9Z62D) is a valid Ethereum transaction.
- However, there was a problem with the second part of the transaction (Pay_hash Hash “Hash1234567890abcDef”). After further research, I found that this payment amount and hash were not actually associated with transactions from the real world.
