Malicious MEV (Maximal Extractable Value) Reduction

Malicious MEV undermines the fairness and efficiency of BNB Chain and decentralized digital ledger world. Many users, especially retail altcoin traders, suffered a lot from Sandwich attacks and lost hundreds of millions of dollars. The BNB Chain community is also eager to find a solution to reduce malicious MEV. (https://x.com/cz_binance/status/1887782360814637259 )

Here we suggest we make BNB Chain unique to turn down malicious MEV as a community. We should take steps to help, discourage, and even penalize those who facilitate and introduce malicious MEV into the BNB Chain. All infrastructures, including but not limited to block builders, RPC nodes, validators, and Dapps, should have their ways of detecting and preventing malicious MEV. Particularly validators, as the block proposers and the ones enjoying the commissions, should take full responsibility to help users from such exploits.

Here we suggest that the BNB community should take all technology and non-technology weapons to reduce malicious MEV, such as:

Bring in potential penalties to the bad players

• Disconnect malicious block builders
• Vote out irresponsible validators

In 2025, a new BEP (BNB Evolution Proposals) will be introduced to technically reduce transaction exposures and improve mempool efficiency

At the same time, we are encouraging all of you to:

• Share the bad players who facilitate malicious MEV
• Use MEV protected wallets
• Stop using unsafe RPCs
