22:30 - Can I spin up MEV Geth and start receiving bundles of Flashbots on my own? Is there a process in place to receive the bundle?
25:15 - xDAI MEV
26:17 - Eth2 MEV
27:22 - Why is MEV in Eth2 important for validators to look at?
27:50 - How to make sure that this MEV is available equally to the small validator the same way it is available to the big validator?
28:11 - Before the Merge
29:22 - Proposer, block builders
30:30 - MEV flow diagram in Eth2 (family -1 solution)
31:48 - 2nd solution proposed flow diagram
32:50 - Solution 1/n proposed flow diagram
34:45 - Solution 2/n proposed flow diagram
35:50 - Carrier transaction
36:35 - Block builder recipe example
37:42 - Multiblock MEV
39:16 - MEV-SGX after Eth2
40:57 - Q&A
41:10 - Transaction sequencing is up to the miner. In a perfect blockchain, would there be an arbitrary transaction that a miner can defect? Is it better the way it is?
45:07 - Game theory
45:58 - Does the distribution of the validator affect in any way?
48:05 - How often speed is a factor in a bundle? How often do we see a bundle that needs to be executed really ASAP? Is that a significant percentage?
49:43 - White hat sweeps
50:56 - In Eth2, you know in advance that the validator will create block x. In case when tx needs to be processed ASAP, setups like that will cause bundles to be published later?

56:00 - Fee-based forking attack,
56:55 - What’s the purpose and what’s the main drive for MEV? A summary.
