Maximal Extractable Value (MEV) is a concept that has become central to the blockchain industry, particularly in the context of decentralized finance (DeFi). MEV refers to the profit that miners, validators, and other participants can extract from the ordering, censoring, or inserting of transactions within a block. The players in MEV include users, wallets, searchers, builders, and miners, each with distinct roles and incentives. In this article we will go deeper into the MEV landscape around the BNB Chain Ecosystem.
The industry's progress on MEV has been significant, with various solutions being developed to mitigate its negative impacts and enhance efficiency. BNB Smart Chain community has worked a lot regarding MEV since early 2023, and is finally on the path to deliver MEV solutions to all the validators.
The Ethereum ecosystem has been at the forefront of addressing MEV challenges and has implemented several innovative solutions to mitigate its effects. Here's a highlight of some of the current technical solutions within the Ethereum ecosystem:

Flashbots is an open-source, permissionless, and transparent solution for MEV (Miner Extractable Value) extraction on Ethereum. As BSC is EVM based, It can naturally be replicated for BSC with some modifications. The introduction of mev-boost in Ethereum has created a win-win situation for Searchers, Block builders, and Proposers. For this reason, BloxRoute team worked on a proposal that aims to implement the same profit-maximizing and profit-sharing spirit on BNB Smart Chain.
The MEV-Relay will propose potential blocks to connected Validators. Unlike Validators, the MEV-Relay can receive transaction “bundles” constructed by MEV Searchers, allowing for the maximization of profit for all stakeholders.
The architecture integrates the roles of searcher, builder, and relay to produce the most profitable block using an MEV builder. However, there are extra modifications required for the validator program.
MEV-Relay Proposing Blocks: Within a given block, the MEV-Relay can propose multiple blocks if a new block offers a better reward. The validator validates and seals each proposed block that improves the value.
The Flashbots-like solution for BSC by BloxRoute represents a significant advancement in maximizing profits and efficiency within the BNB Smart Chain. While it offers numerous benefits such as profit maximization, transparency, and enhanced functionality, it also comes with challenges related to customization complexity, potential security concerns, and timing constraints. Careful consideration and robust implementation are essential to leverage the pros while mitigating the cons of this innovative solution.
In the context of BSC, implementing MEV solutions can be complex and potentially risky for the network stability as block size increases and number of validators expand. Utilizing Sentry Nodes as part of the MEV solution offers a way to mitigate these risks and enhance network stability.
The architecture focuses on the use of Sentry Nodes, which act as protective barriers for validator nodes, ensuring that the network can sustain denial of service attacks. The key features of this architecture are:
In the P2P network, transactions can be propagated in two ways:
MEV Builder Integration
The MEV builder can be integrated into sentry node architecture to prioritize the extraction of MEV. By ensuring that the Sentry Nodes only send the transaction hash to the validator node, and having the MEV builder send the complete transaction, the MEV builder gains an advantage in transaction arrival time. This priority allows for more efficient and effective MEV extraction.
Some benefits in Implementation via Sentry Node:
The utilization of Sentry Nodes as Web3 in the BSC network for MEV implementation can offer a robust and efficient solution. By focusing the implementation on the Sentry Nodes and integrating the MEV builder, this architecture ensures security, stability, and efficiency. It represents a promising alternative direction for the ongoing development and enhancement of the BSC network, aligning with the broader goals of transparency, profitability, and resilience in the blockchain ecosystem.
The BSC network faces a complex landscape in implementing MEV solutions, with different approaches offering unique benefits and challenges. Two emerged solutions: the Flashbots-like solution introduced by BloxRoute and the Sentry Node architecture. Both approaches have their merits, but they also present distinct challenges that must be carefully navigated.
The Flashbots-like solution offers a transparent and open-source approach that maximizes profits for all stakeholders. However, it requires significant customization and potentially introduces security vulnerabilities and centralization risks. On the other hand, the Sentry Node architecture emphasizes security and stability by isolating the validator nodes and focusing the MEV implementation on the Sentry Nodes. This approach offers enhanced security, scalability, and efficiency but may also present its own complexities and limitations.
MEV represents a complex interplay between various stakeholders, each seeking to maximize their gains while maintaining network stability and integrity. Several architectural solutions have emerged to address the challenges of MEV, including Flashbots-like solutions and Sentry Node utilization. These approaches leverage diverse expertise and innovative solutions within the community, aiming to create a win-win scenario for all involved.
