Ethereum: How transaction fee is calculated in case of L2?
Ethereum: How is the transaction fee L2 (layer 2) transactions?
When it comes to Ethereum’s transactions, especially those related to the 2nd layer (L2) solutions, such as optimism and polygonal, calculating the transaction fee can become difficult. In this article, we will go into how these fees are calculated in the case of L2 transactions.
Business Fee of Transaction
It is important to understand how traditional Ethereum’s transactions work before diving into the specifics of L2. When the user sends the ether (ETH) from his wallet to another address on the Ethereum network, the transaction fee is paid to the sender as part of the gas price. The more expensive the transaction, the higher the gas price and then the higher the transaction fee.
Layer Transactions: Gas Efficiency and Pay
L1 transactions use the traditional Ethereum Provision (POW) consensus mechanism for networking. In contrast, L2 solutions, such as optimism and polygonal, are aimed at reducing congestion and processing time by discharging some of these calculations to specialized nodes in the L2 layer.
In order to optimize gas efficiency, many L2 solutions have introduced new transaction paid models that take into account factors such as:
1
Gas ​​use : The amount of computing resources required to process the transaction.
- The complexity of the transaction : More complex transactions require more computing resources.
3
Liquidity : Transactions associated with high value or high complexity assets may result in higher charges.
L2 Calculation of transaction fees **
Now that we have looked at the basics, dive into how these fees are calculated in the case of L2 transactions.
In traditional Ethereum transactions, transaction fees are usually calculated as a gas price and a gas -use product. However, this approach is less applicable to L2 transactions. Instead, most L2 solution uses a more sophisticated model that takes into account a variety of factors to determine the optimal transaction fee.
Here is an example:
Let’s say we have two users, Alice and Bob, who want to send 1 Eth of their wallets in different chains (like Ethereum Mainnet and Optimism).
Alice
: Send 1 Eth of her wallet to Bob’s wallet for optimism using a simple gas -paid model:
Txfee = Gasprice * Gasuage
= 5 * 100,000,000,000 USD (Gas Use) + 0.001 USD (Gas Price)
≈ 500,000,001 USD
Bob : Send 1 Eth from your wallet to Alice’s wallet Ethereum Mainnet using a more sophisticated model that takes into account the complexity of the deal and the liquidity involved:
Txfee = Gasprice * (Gasage + Liquidy)
= 5 USD * (100,000,000,000 000 USD + 50,000,000) / 1,000,000
≈ $ 500,000
In this example, we see that Bob’s transaction fee is significantly higher due to a more complex transaction and lower gas use.
Conclusion
Calculation of L2 transaction fees includes a combination of factors such as the use of gas, complexity, liquidity and network congestion. While traditional Ethereum transactions use a simple gas price gas pattern, L2 solutions have introduced more sophisticated models that take into account these variables to optimize the efficiency of gas and reduce the transaction fee.
As the Ethereum ecosystem continues to develop, it is important to keep track of the latest trends and innovations in the calculations of the L2 transaction fee.
