In a decisive move, the Solana Foundation has expelled several validator operators from its delegation program for their involvement in sandwich attacks. This strict enforcement action, highlighted by Solana Validator Relations Leader Tim Garcia, reiterates the foundation’s commitment to combating malicious activities within its network.
Why Did Solana Act Against Mempools?
The crackdown targets operators participating in mempools that facilitate sandwich attacks. Garcia stated on the Solana Foundation’s Discord server that these enforcement actions are final and will continue to identify and remove those involved in such harmful practices. The foundation’s actions reflect its dedication to upholding network integrity and user protection.
What Are Sandwich Attacks?
Sandwich attacks involve placing two transactions around a victim’s transaction to manipulate prices and profit from the difference, violating the foundation’s rules. Helius co-founder Mert Mumtaz emphasized that removing validators engaged in these acts upholds the foundation’s commitment to ethical behavior and user safety.
The delegation program aims to support validators by delegating SOL coins, eliminating the need for significant coin holdings. However, it requires adherence to good practices and ethics. Those found violating these principles are permanently removed, forfeiting all delegated stakes from the foundation.
Despite removal, affected validators can still contribute to the Solana blockchain due to its permissionless nature, but they will no longer receive foundation subsidies.
Impact of MEV Issues on Solana
Maximal Extractable Value (MEV) issues in Solana include transaction manipulation for profit, such as front-running and sandwich attacks, leading to higher costs and slippage for users. The foundation’s actions aim to mitigate these issues, ensuring a fair and secure network environment.
Concrete Inferences for Users
– Removing validators involved in sandwich attacks enhances network security.
– Validators must adhere to ethical standards to benefit from foundation support.
– Solana Foundation’s actions aim to reduce transaction exploitation and protect user interests.
By enforcing strict rules and removing violators, the Solana Foundation strives to protect its network’s integrity and shield users from exploitative practices, promoting a reliable and efficient blockchain ecosystem. This approach ensures that only ethical and high-performing validators benefit from the foundation’s support.
