Re: Flashbots
#2In Ethereum, as of May 2022, it is believed that over 90% of miners are connected to the Flashbots server. One can determine this by observing that over 90% of blocks contain Flashbot transaction bundles. Adoption from 0% to around 90% occurred almost entirely within 2021.
Flashbots is a single centralised entity. It is funded by Fred Ehrsam’s crypto VC firm Paradigm, although it appears that this funding could be altruistic. Searchers send there MEV transactions to the server with the address https://relay.flashbots.net/ and the server is currently located in Ohio in the United States of America.

10% decentralized. But hey, something is better than nothing.

#5> Therefore, block producers and searchers require complex systems similar to those of a sophisticated trading house, like Alameda Research or Jump for example. This can therefore result in significant centralisation pressures for block producers, with smaller less sophisticated block producers being unable to compete.
I want to make sure I have this straight. The "therefore" in this paragraph refers to how miners "require" a way to front-run orders, bets, and other transactions made on the network lest they fall behind their peers in the mining arms race. The article calls this "Miner Extractable Value" or MEV.
So the centralization pressure from Flashbot comes from miners front-running "DeFi" (decentralized finance) players.
> The Flashbots system is integrated into the current Proof of Work (PoW) mining system on Ethereum. When the Merge happens and PoW mining is switched off, Flashbots adoption will reset to zero again. In order to mitigate against the MEV problem a new Flashbots infrastructure will need to be built up and staking agents will need to adopt this new system. This was not in the ETH 2.0 roadmap and may be an additional complication related to the upgrade to ETH 2.0.
This part is not as clear. How does the MEV landscape change in post-merge Ethereum?

#10This isn't quite what it says it is. This is also pre-merge.
Mining pools, not miners, connected to the flashbots mempool to pick up their transactions. There can be many mempools and mempools don't need to talk to each other. It was in the benefit for the miners for pools to do this (ie: their customers), so all the big ones did it.
By doing so, miners would earn extra value (aka: MEV) from these transactions because flashbots would bundle them up and order them. If you wanted to be at the top of the list with your transactions, you'd pay a bit more.
The really centralized bit of this is that flashbots actually can be turned on/off [0], which I find rather inexcusable.
