BNB Chain Launches Good Will Alliance to Combat Sandwich Attacks

BNB Chain has introduced the Good Will Alliance, a collaborative initiative aimed at mitigating malicious maximal extractable value (MEV) practices, with a particular focus on combating sandwich attacks. These attacks involve malicious actors exploiting the order of transactions to manipulate prices and extract value, often at the expense of retail traders. The alliance's primary objective is to promote the reduction of these attacks and foster a more secure and transparent environment within the BNB ecosystem.

The Good Will Alliance's first initiative is to aggressively push for the reduction of sandwich attacks on the BNB Smart Chain (BSC). Two key builders of the BNB Chain infrastructure, BlockRazor and 48 Club, have already integrated "sandwich attack" filters into their block-building mechanisms. This marks the initial step in the alliance's efforts to combat these attacks and encourages all BSC builders to join this endeavor and implement similar filters.

Moving forward, the alliance plans to take additional steps to counter sandwich attacks. These steps include defining the concept of sandwich attacks, creating tools to identify and measure these attacks, and fostering community cooperation to develop more infrastructure for detecting and preventing such attacks. By promoting these measures, the alliance aims to enhance the overall security and integrity of the BNB ecosystem.

The launch of the Good Will Alliance underscores BNB Chain's commitment to addressing MEV attacks and ensuring a fair and transparent environment for all participants. By coordinating efforts and promoting best practices, the alliance seeks to create a more robust and secure blockchain ecosystem. This initiative is expected to gain wider acceptance through governance processes, BNB Evolution Proposals (BEPs), and regular codebase updates, further solidifying the alliance's impact on the BNB ecosystem. The alliance's efforts are part of a broader strategy to foster creative ideas, best practices, and ethical standards that benefit all participants within the BNB ecosystem.

The initiative received strong community endorsement, evidenced by a DAO proposal that passed with 79% approval on February 14. The proposal highlights the necessity of community-driven measures, including penalties for malicious builders, exclusion of irresponsible validators, and adoption of safer RPC nodes and MEV-protected wallets. The Good Will Alliance plans to continue expanding its scope, actively seeking additional members to introduce further community-oriented security projects throughout 2025.
