Understanding the priority of Ethereum’s event in Mempool

Understanding the priority of events in the Ethereum block chain is crucial about the implementation of Ether in Ethereum. However, as you have stated, there have been cases where transactions are not confirmed in the order of the gas fee, even if they have lower fees.

In this article, we are studying the mechanics behind the transaction priority of Ethereum and explains why this can happen.

MEMPOOL -queue

Ethereum Mempool is a decentralized queue that allows users to send events for certification. Mempool users who want to send ether (ETH) to other nodes or wallets. When new events are delivered, they are related to the Mempool queue and are waiting for verification.

Transaction Priority

The priority of the transactions of the Mempool queue is determined by a combination of factors, including:

• Gas ​​Price : Gas prices are lower priority.

• Number of gas fee : The amount of ether paid for the sender’s wallet affects the priority of the trade.

• Transaction priority order

  : The order of delivery of transactions affects their priority.

Why the lower reward is not confirmed first

When the new event is delivered, it is related to the Mempool queue with other pending events. To ensure that only legal events are performed first, Ethereum uses a priority -based system. However, there have been cases where the transactions of lower rewards have not been confirmed.

This can happen in many ways:

• * Gas ​​Price Ceiling : If the price of the trade exceeds the use of the estimated gas (eg by sending 100 ether to contract), it can be run at the end of the queue.

2

• Mempool overload : If Mempool is overloaded, high priority transactions must not be confirmed due to congestion.

Mitage the problem

To minimize the effect of this problem, developers and users can take several action:

• Use the “Etgasprice” command tool

  to evaluate the use of gas price for certain actions.

• optimize transaction structures , as using less gas -intensive functions or by reducing the number of gas -paying calls.

• Follow Mempool congestion using tools such as Infura’s “Mempool` application subscription or third -party services.

In summary, the transaction priority of Ethereum works necessary to optimize etherproofing and avoid any problems. By looking at these mechanics and implementing the best practices to alleviate the problem, developers can ensure that high priority transactions will first be repaired.
