The Dencun upgrade was designed to enhance Ethereum’s performance by lowering transaction costs and improving efficiency on Layer 2 solutions. These Layer 2 networks are built on top of the main Ethereum blockchain to handle more transactions at a lower cost, easing the load on the primary network. With lower fees and faster processing, the upgrade was expected to make Ethereum more user-friendly and scalable.

Unexpected Challenges: Rising Transaction Failures

Despite its goals, the Dencun upgrade has led to a troubling rise in transaction failures on Ethereum’s Layer 2 solutions. A recent report from Galaxy Digital highlights that Base, a Layer 2 network run by Coinbase, has seen its transaction failure rate soar to 21%. Similarly, Arbitrum and OP Mainnet, two other prominent Layer 2 solutions, are experiencing failure rates of 15.4% and 10.4%, respectively.

These numbers are particularly concerning because they contrast sharply with the overall performance metrics. Transactions involving Maximal Extractable Value (MEV) bots are seeing even higher failure rates. On Base, MEV bots are responsible for an alarming 41.6% of failed transactions. Arbitrum and OP Mainnet also report high failure rates for transactions involving bots, at 20.87% and 12.85%, respectively.

Understanding MEV Bots and Their Impact

MEV bots are automated programs designed to exploit opportunities within blockchain networks. They manipulate the order of transactions to extract maximum value, often at the expense of regular users. With the Dencun upgrade reducing transaction fees, these bots have become more active. Their increased presence is contributing to the higher failure rates seen across Layer 2 networks.

Impact on Ethereum’s Revenue

The surge in transaction failures is also affecting Ethereum’s overall revenue. Since the Dencun upgrade, the network has experienced a dramatic 69% drop in average moving revenue. This decline is largely due to a sharp reduction in Ethereum’s burning volumes on the Layer 1 blockchain. Prior to the upgrade, Ethereum’s burning mechanism helped counteract inflation by removing tokens from circulation. However, the lower transaction fees introduced by Dencun have led to an 84% drop in burning volumes, resulting in a more inflationary environment.

Inflation Concerns and Long-Term Effects

The shift towards a more inflationary Ethereum network could have significant implications for the cryptocurrency’s long-term stability. Ethereum’s reputation as a reliable store of value may be undermined by this increased inflation. Investors and users might be concerned about the network’s ability to maintain its value and security over time.

Proposed Solutions to Address the Issues

In response to these challenges, Ethereum co-founder Vitalik Buterin has proposed several strategies to mitigate the impact of the Dencun upgrade. One key proposal is the use of “inclusion lists.” This method would require builders to include specific transactions in each block proposal, potentially reducing the influence of MEV bots and enhancing network decentralization. Other suggested measures include minimizing bot activity through quarantine techniques and adjusting node requirements to maintain network integrity.

The Road Ahead for Ethereum

As Ethereum continues to navigate the effects of the Dencun upgrade, addressing these new challenges will be crucial. While the upgrade aimed to improve Layer 2 solutions, the rise in transaction failures and MEV bot activity highlights areas that need further refinement. By implementing proposed solutions and tackling inflationary trends, Ethereum can work towards stabilizing its network and ensuring its continued growth and adoption.

Conclusion

The Dencun upgrade has had a mixed impact on Ethereum, with both positive and negative outcomes. While it aimed to make transactions cheaper and more efficient, it has also led to a rise in transaction failures and MEV bot activity. The resulting decline in revenue and shift towards inflation raise important questions about the network’s long-term stability. As Ethereum adapts to these challenges, ongoing improvements will be essential to maintaining its position as a leading cryptocurrency.
