According to Foresight News, the Solana Foundation has announced the removal of a group of validator operators from its delegation program. This action was taken in response to their involvement in 'sandwich' attacks on Solana users. Mert Mumtaz, the co-founder of Solana RPC provider Helius, explained that this move will ensure that the foundation does not delegate to validators who carry out malicious sandwich attacks on retail users.
A 'sandwich' attack is a type of malicious activity where an attacker manipulates the price of a cryptocurrency by executing trades in quick succession. This type of attack can cause significant financial loss for the targeted users. The Solana Foundation's decision to remove the implicated validators from its delegation program is a step towards safeguarding the interests of its users and maintaining the integrity of its network.
