In almost all cases, we do not know with any certainty that our hardware is executing the expected program and that it is not actually acting against us. Many cases of exactly this kind of betrayal have been uncovered. The latest proved deadly. This precedent suggests the likely existence of undetected malicious hardware in use today.]]></description>

            <description><![CDATA[We introduce a new approach to block building called parallel block building. Instead of treating all transactions as potentially conflicting - as traditional sequential building algorithms do - parallel block building recognizes that most transactions in a block are actually independent. When a user swaps ETH for USDC, it doesn't affect someone minting an NFT - so why process them sequentially?]]></description>

            <description><![CDATA[Recent months have seen an awakening of several large use cases of TEEs, from OpenAI calling for new and improved TEEs and Apple announcing a hardware-based private cloud, to Ethereum transactions being privately processed in TDX and other blockchains leveraging SGX for integrity. Having worked quite closely with several use cases that are at the center of this excitement, we are aware of both the promise which secure hardware holds, and of the current insufficiency of today’s hardware to service these use cases. TEE solutions currently on the market simply do not offer sufficient security guarantees while alternative secure hardware families like TPMs, secure elements and smart cards offer better (although not perfect) security guarantees at the cost of needed performance and functionality. For the first time, there is substantial industry demand for high-power, high-performance hardware that is secure under a comprehensive threat model.]]></description>

Our approach allows searchers to blindly backrun user transactions using FHE. This prototype demonstrates how a searcher can compute the future price of a UniswapV2 pool over a user transaction, keeping it encrypted throughout the process. Although this method is not currently practical for deployment, it serves as a foundation for future improvement and expansion, which we discuss in the conclusion.]]></description>

            <description><![CDATA[Flashbots has been critical to leveling the MEV playing field on Proof-of-Work (PoW) Ethereum (eth1), and aims to bring the same benefits to Proof-of-Stake (PoS) Ethereum (eth2). The adoption of Flashbots involves two distinct parties, block producers, and MEV searchers. In Ethereum, over 90% of miners have adopted Flashbots; however, as we approach eth2 and the transition to PoS, adoption will reset to 0. As such, for the health of the Ethereum ecosystem, it is imperative that validators also adopt an MEV solution for Ethereum post-merge. To assist in this adoption, we are pleased to announce the Flashbots Eth2 Working Group.]]></description>

This trust based solution closely resembles the current Flashbots auction design with modifications to enable solo staker participation without introducing changes to Ethereum consensus. This solution aims to bridge the gap to a permissionless PBS design which should be strongly considered for the cleanup fork in order to improve decentralization.]]></description>

            <description><![CDATA[The beating heart of every blockchain is how space is allocated within a block. In less than 24 hours, Ethereum will undergo a historic change to how blockspace is allocated as transaction inclusion rules drastically change with the activation of EIP-1559. However, EIP-1559 does not affect miners’ ability to reorder, insert, or censor transactions, and as such it largely does not have an impact on MEV (Maximal Extractable Value).]]></description>

            <description><![CDATA[The incorporation of EIP-1559 in the London hardfork brings a major restructuring of the Ethereum fee mechanism, aiming to allow for easier fee estimation by users and consolidate ETH as the base currency of the network by burning part of the transaction fees. This post analyzes some of the consequences of this EIP under the light of the MEV (Maximal Extractable Value) phenomenon, that is, the permissionless extraction of value by the reordering, addition, or censoring of transactions.]]></description>

It is not completely private because bundles can be seen by miners prior to inclusion on-chain. Lastly, Flashbots Alpha offers no finality protection against chain reorgs.

            <description><![CDATA[Maximal (formerly Miner) Extractable Value ($\textrm$) is the value that can be extracted from a blockchain by any agent without special permissions. Considering this permissionless nature, any agent with transaction ordering rights will be in a privileged position to perform the extraction. In Proof of Work blockchains, it is miners who determine transaction ordering within a block, hence the former "miner" term. In practice, bot operators seek to extract $\textrm{MEV}$ by either paying high fees to increase the likelihood that their transactions are mined, or by fine-tuning their gas price choices in order to "time" their transactions right, as is the case when backrunning an oracle update to perform a liquidation.]]></description>
