Ethereum: Transaction Priority in Producing Block

Understanding of the transaction priority of Ethereum in Mempool

When it comes to performing ether transactions on the Ethereum blockchain, understanding the priority of transactions is of crucial importance. However, as you noticed, there were cases in which transactions are not confirmed in the order of the gas fee, even if they have lower fees.

In this article we will deal with the mechanics behind the transaction priority in Ethereum and explain why this can happen.

The Mempool -Kartzeiten

Ethereum’s Mempool is a decentralized queue in which users can submit transactions for checking. The mempool is populated by users who want to send ether (Eth) to other nodes or to their wallets. When new transactions are submitted, join the Mempool -Wegertschlang and wait for check.

Transaction priority

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

• Gas ​​price : Transactions with higher gas prices have a lower priority.

• Gas ​​fee amount : The amount of the ether paid to the sender’s wallet affects the priority of the transaction.

• Priority order

  : The order in which transactions were submitted affects their priority.

Why transactions with lower fairy are not confirmed first

When a new transaction is submitted, it combines with other outstanding transactions in the Mempool. To ensure that only legitimate transactions are carried out, Ethereum uses a primary system. However, there have been cases in which transactions with lower fairy have not received their duly confirmation.

This can happen in different ways:

• Gas ​​price limit : If the gas price of a transaction exceeds the estimated gas consumption of the company (e.g. 100 ether on a contract), it can be pushed to the end of the queue.

• Transaction prioritization order : The order in which transactions have been submitted can lead to transactions with lower fairies to be executed in front of higher -paid versions, even if they have lower fees.

• Mempool overload : If the Mempool is overloaded, transactions with high priority may not be confirmed due to overload.

Mastive the problem

In order to minimize the effects of this problem, developers and users can take several steps:

• Use the “ETHGASPRICE”

  command line tool to estimate the use of gas prices for certain operations.

• Optimize transaction structures , such as

• Overload of Mempool by using tools such as Infura’s “Mempool” API or third -party services.

In summary, it is important to understand how the transaction priority of Ethereum for optimizing ether transactions and avoiding potential problems works. By capturing these mechanics and implementing best practice to reduce the problem, developers can ensure that transactions with high priority first receive their due confirmation.
