What do we call the queue where transactions submitted to the network wait before entering a block?

The queue where transactions submitted to the network wait before entering a block is called the mempool.

Here’s a breakdown of how it works:

1. Transaction Submission: When a user initiates a transaction, it’s broadcast to the network’s nodes.
2. Mempool Entry: Each node maintains its own mempool, where incoming transactions are temporarily stored.
3. Validation: Nodes verify the validity of transactions in their mempools, ensuring they adhere to the network’s rules.
4. Prioritization: Transactions are prioritized based on factors like:
   • Transaction fees: Higher-fee transactions generally get chosen first.
   • Age of transaction: Older transactions may be prioritized to prevent congestion.
   • Transaction size: Smaller transactions may be selected for efficiency.
5. Block Inclusion: Miners, responsible for creating new blocks, select transactions from their mempools to include in the next block.
6. Block Creation and Broadcast: Miners construct a block, add the chosen transactions, and broadcast it to the network.
7. Block Confirmation: Other nodes validate the block and add it to the blockchain if it’s valid.
8. Transaction Completion: Once a transaction is included in a confirmed block, it’s considered successfully completed.

Key Points:

• The mempool is essential for managing transaction flow and ensuring network integrity.
• Mempool size and transaction fees can fluctuate based on network activity.
• Understanding the mempool is crucial for estimating transaction confirmation times and assessing network health.
