Solana Foundation announced the exclusion of a group of node operators from the delegation program due to their participation in "sandwich attacks" against users. This was announced by Tim Garcia, head of the department for relations with blockchain validators, in the Discord channel.
"Decisions on this issue are final. We will continue to take enforcement action against operators involved in mempools that allow sandwich attacks, "Garcia wrote.
Back on May 7, a representative of the organization warned that such activities are contrary to the rules of the ecosystem.:
"The delegation program does not allow operators who engage in malicious activities, such as participating in a private mempool for sandwich attacks or otherwise causing harm to Solana users. Anyone found guilty of such activities will be excluded from the program, and the Solana Foundation's share will be immediately and irrevocably canceled."
This step ensures that the foundation will not delegate authority to validators who perform malicious actions against retail users, said Mert Mumtaz, CEO of RPC provider Helius Labs.
He explained that a "sandwich attack" is a malicious form of MEV bots that extracts all the profits from certain trades, leaving ordinary traders with assets at the worst prices.
According to Mumtaz, initially such operations were impossible to perform in Solana, since the blockchain client did not have a mempool. However, some validators have added "modifications".
"The Solana Foundation delegates SOL to validators to help them get started. Since people abuse the system to rob retail traders and keep all the profits for themselves, the network fund is not interested in this, especially using their own funds, " said the CEO of Helius Labs.
Mumtaz also stressed that excluded validators will be able to continue to participate in the management of the blockchain, but only without funding from the Solana Foundation.
Previously, the operator of the MEV bot jaredfromsubway. eth spent more than 215 ETH (~$830,200) on commissions and became the largest gas consumer in Ethereum.
Recall that the co-founder of the network Vitalik Buterin attributed MEV to the three main threats to the decentralization of the network, along with liquid staking and the cost of launching a full node.
The EU regulator called the technology a prime example of market abuse.
