Understanding Flashbots and its Related Services

---

FlashBots

A research and development company called Flashbots is attempting to reduce the unfavorable side effects of the present Maximal Extractable Value (MEV) extraction methods and prevent the existential concerns MEV might pose to state-rich blockchains like Ethereum.

What is MEV?

The Full form of MEV is the Maximal extractable value. Maximal extractable value (MEV) means the maximum amount of additional value that can be obtained by rearranging and choosing which transactions to include in a block, beyond the usual rewards and fees that are earned for validating transactions in a blockchain network.

Flashbot Auction

Flashbots Auction is a decentralized and open system that allows for efficient extraction of MEV (miner extractable value) and protection against frontrunning while maintaining the values of the Ethereum network. It provides a secure and confidential communication channel between Ethereum users and validators, enabling them to communicate their desired transaction order within a block.

Flashbots Auction operates through a private transaction pool and a sealed bid block space auction mechanism, which enables validators to outsource the task of finding the best block construction in a trustless manner. This mechanism is designed to ensure fairness, transparency, and efficiency in the MEV extraction process while preventing frontrunning.

Flashbot Data

The platform offers various services and dashboards that enhance the visibility of MEV (miner extractable value) activity on Ethereum and the Flashbots Auction. These sub-services include tools and features that provide more insight into how MEV is being extracted and utilized on the network.

1.) Mev-inspect 

If provided with a block, the system is capable of identifying several key pieces of information, including the payment made to validators (in the form of gas fees and coin base rewards), as well as any token transfers and resulting profits from those transfers. Additionally, the system can also identify any swaps or arbitrages that occurred within the block.

2.) Mev-blocks 

The platform provides a publicly accessible API that allows users to view flash bots blocks and transactions. As Ethereum is moving towards a PoS consensus mechanism, the API has been updated to include additional fields in the Blocks API response that are aligned with the PoS Ethereum naming conventions.

3.) Mev-explore

MEV-Explore v0 is a dynamic tool that presents a real-time overview of the MEV (miner extractable value) activity taking place on the Ethereum network. It also includes an MEV transaction explorer, allowing users to explore the details of these transactions.

Flashbots Protect 

Flashbots Protect simplifies the process of utilizing Flashbots for protecting against frontrunning for both developers and everyday users. It eliminates the complexity involved in submitting bundles to the Flashbots Auction and can be integrated by simply adding a URL to MetaMask. Users can add the Flashbots Protect RPC as an RPC endpoint to their wallets to submit transactions to Flashbots.

By integrating Flashbots Protect, users can enjoy various benefits, including protection against frontrunning by sandwich bots in the public mempool, transactions being included only if they do not result in reverts, and avoiding paying for failed transactions. Transactions can be tracked using Etherscan, providing greater visibility and transparency.

MEV-Boost

Mev-boost is an open-source middleware that validators use to access a competitive block-building market. Flashbots created MEV-Boost as an implementation of proposer-builder separation (PBS) for PoS Ethereum, where builders produce blocks containing transaction order flow and a fee for the block proposing validator. For Ethereum, separating the functions of block proposers and builders promotes competitiveness, decentralization, and censorship resistance.

MEV (miner extractable value) can have a centralizing effect on Ethereum, and without intervention, the competition for MEV opportunities can lead to instability in consensus and the establishment of permissioned communication channels between searchers, block producers, and validators. As the reduction in block subsidies in PoS Ethereum will increase the importance of MEV as a source of staking revenue, access to MEV is crucial for validators.

By offering their block space on an open market, validators employing MEV-Boost can maximize their stake payouts, potentially increasing them by over 60%

MEV-Share

MEV-Share is a protocol that operates on an open-source basis and aims to enable permissionless collaboration between users, order flow providers, and searchers using privacy and commitments. It is designed to be credibly neutral and does not favor any particular block builder, and searchers can participate without permission. It can lessen the centralized influence of proprietary order flow on Ethereum by aggregating it to MEV-Share while allowing wallets and other sources of order flow to participate in the MEV supply chain.

On the other hand, validators can access a competitive block-building market using the open-source middleware MEV-Boost. To implement proposer-builder separation (PBS) for PoS Ethereum, where builders produce blocks containing transaction order flow and pay a fee to the block-proposing validator, Flashbots created the technology. Ethereum benefits from competition, decentralization, and censorship resistance because of the division of block proposers and constructors.

Since MEV can have a centralizing effect on Ethereum, the competition for MEV opportunities can lead to instability in consensus and the establishment of permissioned communication channels between searchers, block producers, and validators. As the reduction in block subsidies in PoS Ethereum increases the importance of MEV as a source of staking revenue, access to MEV is crucial for validators. By using MEV-Boost, validators can potentially increase their rewards by over 60% by selling their block space on an open market.

For Users

By linking your wallet with Flashbots Protect, your transactions will be directed to MEV-Share, and you can capture the MEV generated by your transactions.

For Searchers

If you want to search for MEV on MEV-Share, you need to connect to a matchmaker. The matchmaker receives transactions and bundles from users and selectively shares information about transactions with searchers. The matchmaker swaps the transaction's hash with the original transaction before sending the bundle to a block builder when a searcher wants to include a transaction in their bundle.
