Solana Takes Action Against Validator Misconduct and Prepares for Mainnet Upgrade
Solana Cracks Down on Validators, Prepares Network Upgrade
On June 10, 2024, Solana Foundation removed several validator operators from its delegation program for participating in sandwich attacks. This type of front-running exploit involves placing transactions before and after a victim's transaction, manipulating prices for profit.
The malicious validators were identified through their participation in mempools, which allowed these attacks. Those caught are permanently barred from the delegation program, and any assigned stake from the Foundation is revoked. This move aligns with Solana's strict rules against such activities to ensure security and fairness for all traders.
Tim Garcia, Solana's Validator Relations Lead, emphasized on Discord that any operators engaging in these activities would not be tolerated. Mert Mumtaz, co-founder of Helius, noted these practices violate Solana’s standards. Despite the removal from the delegation program, the validators can still operate on the network but without financial backing from the Foundation.
Solana has announced the readiness of its v1.18.15 mainnet upgrade, aimed at resolving major congestion issues caused by the launch of Solana-based meme coins. Validators are advised to upgrade when there is less than 5% delinquent stake and report any issues.
The upgrade includes integrating certificate authority certificates into the docker image, bug fixes, metrics for threshold failures, scheduler optimization, and logging shallow threshold checks only during the consensus mechanism.
Following the upgrade announcement and positive market sentiment after the CPI release, the price of SOL increased by 5.3% to $160.38. Solana’s all-time high stands at $260.06, and analysts predict a potential rally to $250 in this bull run. In March 2024, SOL reached $210 but later declined due to delays in Fed rate cuts.
Maximal Extractable Value (MEV) refers to techniques exploiting on-chain transactions, like sandwich attacks, to maximize profits by manipulating transaction ordering. These practices result in higher costs and slippage for users, which Solana aims to mitigate by removing malicious validators. The community and developers are eagerly anticipating the upgrade, with the Foundation's commitment to preventing exploitation evident in its strict enforcement actions and ongoing monitoring.
Conclusion
Solana takes decisive action against malicious validators engaged in sandwich attacks, reinforcing its commitment to security and fairness. The upcoming mainnet upgrade aims to resolve congestion issues, while the community eagerly anticipates the improvements and Solana's continued efforts to mitigate exploitation.
