BNB Chain Launches Good Will Alliance

BNB Chain has launched the Good Will Alliance, intending to combat malicious maximal extractable value (MEV) practices, starting with targeted measures against sandwich attacks.

The initiative aims to unite infrastructure builders, validators, and the broader community to establish ethical standards, best practices, and enhanced security within the BNB ecosystem.

Sandwich attacks, a prevalent form of malicious MEV, have significantly impacted retail traders on Binance Smart Chain (BSC), leading to losses totaling hundreds of millions of dollars, according to BNBChain DAO.

In response, the alliance’s initial actions focus specifically on mitigating sandwich attacks through advanced filtering mechanisms.

Infrastructure providers BlockRazor and 48 Club have implemented specialized sandwich attack filters within their block-building processes, setting an early benchmark for alliance participants. The alliance has created a GitHub repository listing builders compliant with these ethical standards, encouraging BSC validators to accept block bids only from this vetted group.

According to BNB Chain, the alliance’s strategy involves:
– Defining clearer criteria for identifying sandwich attacks
– Developing sophisticated tools to detect malicious MEV behavior
– Fostering deeper community collaboration to enhance on-chain security

These efforts will evolve through governance processes, BNB Evolution Proposals (BEPs), and regular codebase updates, aiming for long-term improvements in network fairness.

The initiative has garnered strong community support, as evidenced by a DAO proposal that passed with 79% approval on February 14.

The proposal highlights the need for community-driven measures, including penalties for malicious builders, exclusion of irresponsible validators, and the 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.
