Blocks

Blocks are the fundamental components of the Quranium blockchain. They store transaction data, link to previous blocks, and ensure the network operates securely and efficiently. QRN Scan provides users with detailed insights into blocks, their contents, and their role in the blockchain ecosystem.

Understanding Blocks

A block contains the following key elements:

• Block Height: The unique identifier for each block in the blockchain.

• Timestamp: The time when the block was mined.

• Transaction Count: The number of transactions included in the block.

• Miner: The wallet address of the miner who validated and added the block to the blockchain.

• Block Size: The total size of the block in bytes.

• Block Hash: A unique cryptographic signature of the block.

• Previous Block Hash (Parent Hash): The hash of the previous block, ensuring continuity and immutability in the blockchain.

• Coinbase Reward Subsidy: The reward given to the miner for successfully mining the block (including the block reward and transaction fees).

• Total Transaction Fees: The total fees collected from the transactions included in the block.

Key Metrics to Analyze in a Block

• Transactions in the Block: Click on the "Transactions" link to view all transactions included in the block. Example:

  • Transaction 1: 351aa0688d7a2274b00ad5f2d27c073575...

  • Transaction 2: 2b3d9e1fae5b12256a883fe08404a9e1f...

• Miner Rewards: The miner who successfully validates the block receives a reward in QRN Coins. Example Reward: 2025.25 QRN (including the block reward and transaction fees)

• Block Fee Summary: View the total transaction fees collected from the block's transactions. Example:

  • Total Fees: 0.25 QRN

• Block Size: The total size of the block in bytes. Example:

  • Block Size: 676 bytes

Pending vs. Confirmed Blocks

1. Pending Blocks:

   • Blocks that are being validated and not yet added to the blockchain.

   • These blocks are visible in the pending block pool.

2. Confirmed Blocks:

   • Successfully validated and added to the blockchain.

   • Confirmed blocks are immutable and contribute to the blockchain's security and continuity.

Example Use Case: Tracking a Block

Suppose you want to track block number 12549 to review its activity:

1. Enter 12549 in the QRN Scan search bar.

2. Review the block’s transaction details, miner information, and total transaction fees.

3. Use the previous block hash (parent hash) (000000001ecf2a9abf8e80be23ed1f4b2c4de7a238d88a8b9fe8b...) to trace the previous block, ensuring the continuity and integrity of the blockchain.

Troubleshooting Block Issues

1. Why can't I find a block?

   • The block may not have been mined yet. Double-check the block number.

2. What happens if a block is orphaned?

   • Orphaned blocks occur when two miners solve a block simultaneously, and only one is accepted by the network. The rejected block is the orphaned one.

3. How do I report incorrect block data?

   • Contact our support team at [email protected] with the block number and details.
