The year 2024 marks a significant turning point for Ethereum (ETH), with the growing dominance of “Dark Pools” redefining the transaction ecosystem on the blockchain. This phenomenon has emerged as a direct response to the need to circumvent front-running bots, automated tools that monitor public transactions waiting in the network queue for economic benefit. However, while these private transactions offer protection against such practices, they are also raising concerns about transparency and the possible centralization of the network.

Private transactions on Ethereum, known as the Dark Pool, have grown from a modest 7 percent in 2022 to account for about 50 percent of total gas use in 2024. This exponential increase is indicative of a structural change in the way advanced users of Ethereum interact with the blockchain. Instead of using public mempools, these transactions are sent directly to validators or block proposers, providing a level of confidentiality that public transactions with other cryptocurrencies cannot offer.

The main features of private transactions include:

  • Protection of information from front-running bots. These bots are designed to exploit pending transactions, inserting themselves into the queue of transactions with the goal of profiting from price fluctuations. Private transactions, bypassing public mempools, make it impossible for bots to monitor and act on this information, thus protecting users’ profit margins.
  • Loss of transparency in transactions. This feature has historically been one of the pillars that has sustained user trust in the blockchain, ensuring that anyone can see and verify all transactions. With an increasing share of activity shifting to private transactions, there is a risk that the network will become less open, with the possibility that investing in cryptocurrencies will become increasingly similar to trading in traditional centralized financial markets.
  • Limited access to private transactions may create a competitive advantage for a few sophisticated players who can afford to see and participate in these exclusive transaction flows. This could lead to a centralization of the network, where only some participants benefit from insider information, contrary to the decentralized nature of Ethereum.

The most accurate measure of the prevalence of private transactions is gas consumption rather than simply counting transactions. Private transactions tend to be more complex and, therefore, require greater use of computational resources. This indicator better reflects the dynamics at work within the Ethereum network.

Opportunities to Regulate

Despite concerns, private transactions also offer opportunities. With the volatility of public transaction fees remaining an issue, the possibility of more stable and predictable transactions could attract more users to Dark Pools. However, this trend must be balanced with maintaining a transparent and accessible ecosystem, essential for long-term growth and trust in the Ethereum network.
