Recently, the interaction between miners and the Ethereum network has reached a record high, but the increase in fuel usage may cause problems for the cryptocurrency network.
According to a recent report from Delphi Digital, the total amount of gas used on the Ethereum blockchain has reached the highest level in history, and it seems that this number will continue to grow. Fuel is a means of charging the Ethereum blockchain. Since the beginning of 2020, the total amount of fuel used on the network has been rising.

The total amount of fuel used is different from the transaction cost indicator in the Bitcoin blockchain. On the Ethereum network, transaction and smart contract fees are determined by the required fuel and fuel prices. This mechanism allows fees to change dynamically and to some extent separate from the price of Ethereum.
The amount of fuel used in a given transaction depends on the computational complexity of the transaction. On the other hand, the price of fuel is selected by the person who executes the transaction and is priced in Ether. The price is ultimately determined by the Ethereum miners, who accept or reject the transaction based on the fuel price.
USDT and decentralized exchanges dominate.Although the fuel usage reached the highest level in history, the number of transactions on the Ethereum blockchain is far lower than the highest historical record of 1,349,890 transactions reached on January 4, 2018.
This means that the increase in total fuel usage comes from the use of more smart contracts. Because smart contracts are more complex, more fuel is needed.
According to data from ETH Gas Station, the usage is mainly from USDT, and the Ethereum fuel cost alone cost $1.61 million. It was followed by DeFi applications and some scams and Ponzi schemes. USDT also leads the average fuel price used, at 35.5 Gwei.
Following the USDT stablecoin, the decentralized exchange (DEX) seems to be in a leading position in terms of popularity. According to DappRadar data, IDEX is the most used dapp in terms of the number of transactions alone, and IDEX and Kyber are both in the top three on the Ethereum network.
A recent survey also showed that DeFi's highest awareness and utilization rate come from decentralized exchanges.
Higher transaction fees and fuel restrictionsThe increase in Ethereum network usage has led to an increase in average transaction fees because miners prefer to handle transactions with higher fuel prices. According to data from glass node, at the time of writing, the average transaction fee has increased five-fold from $ 0.08 in January 2020 to $ 0.41. This also accounts for about 10% of miners' income.
The total fuel usage is limited by the block fuel limit set by the miners, which limits the size of the Ethereum blockchain by determining how many transactions are in a block. The amount of fuel used in each block has been steadily increasing, from 69% in January to the most recent 95%, and is also close to the current upper limit.
Considering the current increase in fuel usage on the network and related block fuel restrictions, due to various factors, Ethereum may face network congestion in the near future. If fuel usage rises to the upper limit, users will have to compete with higher fuel prices to execute transactions and smart contracts.
In addition, a sudden plunge in the price of Ethereum may lead to higher fees and network congestion. As seen during the plunge on March 12, according to a report by The Block, the average fee cost increased from $ 0.16 to $ 1.04.
In this highly volatile situation, traders may find network congestion very troublesome, because the leverage positions of DeFi platforms and centralized exchanges may be liquidated before they take action.
When the usage is close to the limit set by the miners, it may be necessary to increase the block fuel limit. The most recent increase was in September 2019. The block fuel limit was increased by 25%, from about 8 million to about 10 million.
However, this change will further increase the size of Ethereum's blockchain, which has reached nearly 140 GB. Therefore, there seems to be no simple solution, and Ethereum faces considerable challenges in terms of scalability.
