BNB Chain has introduced the Good Will Alliance, with the goal of addressing harmful maximal extractable value (MEV) practices, beginning with focused actions against sandwich attacks.
This initiative seeks to bring together infrastructure developers, validators, and the wider community to create ethical guidelines, best practices, and strengthened security across the BNB ecosystem.
Sandwich attacks, a common type of harmful MEV, have had a profound effect on retail traders on Binance Smart Chain (BSC), resulting in losses estimated at hundreds of millions of dollars, according to BNBChain DAO.
In response to these issues, the alliance’s initial effort is specifically aimed at reducing sandwich attacks through enhanced filtering techniques.
Infrastructure providers BlockRazor and 48 Club have implemented dedicated filters for sandwich attacks in their block-building procedures, setting a preliminary standard for other alliance members. The alliance has also created a GitHub repository that catalogs builders adhering to these ethical standards, encouraging BSC validators to only consider block bids from this approved group.
According to BNB Chain, the alliance’s plan includes establishing clearer definitions for identifying sandwich attacks, crafting advanced tools to detect malicious MEV activities, and promoting deeper community collaboration to enhance on-chain security.
These initiatives will develop through governance procedures, BNB Evolution Proposals (BEPs), and routine updates to the codebase, all aimed at achieving long-lasting improvements in network fairness.
The initiative gained strong community support, as demonstrated by a DAO proposal that was approved with 79% backing on February 14.
This proposal emphasizes the importance of community-led actions, including penalties for malicious builders, the exclusion of irresponsible validators, and the implementation of safer RPC nodes and MEV-protected wallets.
The Good Will Alliance intends to broaden its scope by actively recruiting more members to launch additional community-centered security initiatives throughout 2025.
