Ethereum, the second-largest cryptocurrency by market capitalization, is undergoing a major transition as “dark pools,” which enable secret transactions, become more common. Recent studies conducted by Blocknative, a business that specializes in reducing the effects of Maximal Extractable Value (MEV), reveal that about half of the gas used on the Ethereum network is now coming from private transactions. This change reflects the increasing inclination of knowledgeable users to conduct transactions in private in order to stay away from trading bots and front-running strategies, which might put the network’s pillars of decentralization and transparency in jeopardy.
The Increase in Individual Deals
In contrast to the early days of Ethereum, when transaction processing was mostly done via public mempools, there has been a significant increase in private transactions. When Ethereum switched to a proof-of-stake network in September 2022, only around 7% of the network’s gas was used for private transactions. But by 2024, that number had exploded, with private transactions accounting for about half of Ethereum’s gas use. This trend highlights how private transactions are becoming more computationally intensive than their public counterparts, which adds to their complexity and gas intensity.
Private transactions avoid the public mempools by going straight to validators or block proposers. By using this technique, it is possible to circumvent the MEV problems, in which bots might profit from transaction timing. But as the Ethereum network becomes more and more dependent on private transactions, worries about possible power concentration are mounting. “You have a small number of actors who can see the private flow,” says Matt Cutler, CEO of Blocknative, bringing attention to this problem. There are advantages and opportunities because some individuals can perceive things and others cannot.”
Consequences for the Decentralization of Ethereum
There are advantages to moving to private transactions, such less exposure to MEV and maybe cheaper fees, but there are also big concerns for the Ethereum ecosystem. The increasing dominance of permission-only private transaction order flow may result in a concentration of power among a small number of highly skilled users. This concentration runs counter to the openness and equitable access that are the cornerstones of blockchain technology.
Cutler goes on to say that because private transactions are often more complicated and gas-intensive, this tendency may result in more volatility in charge rates for public transactions. Because of this intricacy, opportunities are not completely realized for everyone; only those with exclusive access to certain network information may do so.
Final Thoughts
The growing prominence of private transactions on Ethereum denotes a significant shift in the way people use the blockchain. With more users choosing dark pools as a way to steer clear of MEV and other hazards, the network is having trouble being open and decentralized. The increase in private transactions highlights the necessity of constant innovation and conversation within the Ethereum community to guarantee that the network stays accessible and fair to all users.
