Understanding Transaction Details

A transaction represents an action performed on the Quranium blockchain, such as transferring QRN coins. QRN Scan displays detailed information about each transaction.

Here’s what you’ll find in a typical transaction detail view:

1. Transaction Hash (TX ID): A unique identifier for the transaction. Example: 351aa0688d7a2274b00ad5f2d27c073575...

2. Block Hash: The block in which the transaction was included. Example: 0000000020871a48675378a04...

3. Timestamp: The time when the transaction was added to the blockchain. Example: 2025-01-22 10:15:30 UTC

4. Input UTXOs: The unspent transaction outputs used as inputs for this transaction. Example: qrnUwFZotS7mKSY8cYP8K5rWR9Ar8NxmY... » 120 QRN qrnPQyTjiBy2gDSbT6tKprTGK1v9Lcs7R... » 80 QRN

5. Output UTXOs: The newly created unspent transaction outputs. Example: qrnfd1TwPKMBQ2Jgyqysn12bY8xxx9Ek1... » 150 QRN qrnfMNVkGvALtw1ribAcPexRZvFhzTQGm... » 49.99950 QRN (Change)

6. Transaction Fee: The amount paid to process the transaction. Example:0.0005 QRN

7. Coinbase Transaction: Indicates whether this is a coinbase transaction (block reward for miners).

   • Yes: This transaction has no input UTXOs and only outputs to the miner's address.

   • No: This transaction follows the standard UTXO model with inputs and outputs.

8. Transaction Status: Indicates whether the transaction was successful, failed, or pending.

Example Transaction

• Transaction Hash (TX ID): 351aa0688d7a2274b00ad5f2d27c073575...

• Output UTXOs: qrnfd1TwPKMBQ2Jgyqysn12bY8xxx9Ek1mj6 → 150 QRN qrnfMNVkGvALtw1ribAcPexRZvFhzTQGm5SF → 49.99955 QRN (Change)

• Transaction Fee: 0.00045 QRN

• Coinbase Transaction: No (This transaction follows the standard UTXO model with inputs and outputs)

• Transaction Status: Success

Pending vs. Confirmed Transactions

• Pending Transactions: These transactions have been submitted to the blockchain but are waiting to be included in a block. They are in the mempool (memory pool), where they await miners' validation.

  • Reason: High network traffic, insufficient transaction fees, or low miner priority.

  • Example: A transaction with TX Hash: 351aa0688d7a2274b00ad5f2d27c073575... remains pending because the transaction fee is lower than the current network average, preventing miners from prioritizing it.

  • Note: Pending transactions are prevented by setting a minimum basic transaction fee on the QRN chain.

• Confirmed Transactions: These transactions have been successfully included in a block and validated by miners. The number of confirmations indicates how many blocks have been mined after the block containing the transaction.

  • Example: A transaction with 1 confirmation means it was included in the latest block, while a transaction with 5 confirmations has been further secured with more blocks confirming its validity.

Troubleshooting Transaction Issues

1. Why isn’t my transaction showing up?

   • Cause: The transaction hasn’t been broadcast to the network or included in a block.

   • Solution: Verify your transaction hash on the QRN block explorer. If it’s still missing, check with your wallet provider to ensure it has been properly broadcast.

2. What does “Transaction Execution Failed” mean?

   • Cause: The transaction might have failed due to invalid conditions (e.g., insufficient fees, invalid inputs).

   • Solution: Ensure you’ve set a sufficient transaction fee based on the network conditions. If it was a coinbase transaction, check that it's properly configured.

3. Why is my transaction “Pending” for too long?

   • Cause: The transaction fee is too low to be accepted by miners, or the network is congested. Pending transactions remain in the mempool until miners include them in a block.

   • Solution: The QRN chain requires a minimum transaction fee for the transaction to be processed. If the fee is too low, the transaction will not be included in the block. Ensure the fee meets the minimum threshold.

4. Why is my wallet balance incorrect?

   • Cause: Pending transactions may temporarily lock the QRN coins involved.

   • Solution: Wait for the transaction to confirm. Once confirmed, the balance will be updated to reflect the confirmed transactions.
