![bread_'s tweet photo. Great Mega TLDR. I very much encourage a read.
I also think people are still sleeping on the elegance of the rotational sequencer design, so I'll explain why I think it's cool.
🔹The feedback loop between user submitting a tx, that tx changing the state of the chain and apps reflecting those changes can be miniscule.
Imperceptible, even.
--------------------
Why is that, and why can't ~most chains achieve that today?
Due to consensus overhead when it's not decoupled from execution. Lets show some pictures.
Here is what a normal block creation flow looks like for any chain that either:
🔹Has consensus (e.g. L1s)
🔹Plans to have consensus (e.g. L2s decentralizing the sequencer)
They will:
• Collect transactions in some fashion (Solana streams to a leader, EVM chains collect in a mempool, etc)
• Build out/propose blocks
• Agree on blocks over their block time (consensus)
• Apps will ingest blocks and show users
Visualized
Things to note:
• We have a variable time (message from user to block builder) and a time with a lower bound of 200ms (consensus), which means cumulative time is at minimum 200ms.
• The consensus step has a static floor because it requires message passing throughout a set of machines of unknown distance. This means you should assume the time it takes for a message to go halfway across the world (avg distance) and back (NY to Tokyo is 200ms, so "halfway" is 100ms)
• The above is a physical limitation, not something to be patched out.
--------------------
Okay, cool, how is MegaETH dealing with it?
We remove consensus entirely, opting for a design where a single machine builds blocks for a period and then is rotated out.
With that move, both times are variable and based on how close both the user and applications are to said block builder (i.e. how co-located they are).
Visualized:
Things to note:
• The design is for an active sequencer, not our active sequencer. That means other parties will be able to run one eventually (and be punished if they misbehave).
• For co-located power users (like market makers), they can achieve <10ms time between tx submission and block being produced and returned to them.
• This is actually similar to what Solana is aiming to do with their async roadmap item (decouple execution from consensus [they already stream to a leader with a slot monopoly]) but that'll be a few years of R&D.
• We can preserve some additional user properties because we're an L2, like bypassing the sequencer altogether to withdraw your ETH to mainnet.
--------------------
WRAPPING UP
I had no intentions of writing this today, but reading that thread got me excited about what we're doing so I wanted to dig in.
We're going to hit a new tier of onchain performance with what should have been (in my eyes) a very obvious construction. A tier that cannot be achieved if your chain has not separated consensus from execution.
We're going to make fun denominated in $ETH again. More to come.](https://pbs.twimg.com/media/GeIjm02XUAA7KvE.jpg)

Here is how the first 1,000 @megaeth quizzes scored after de-duping. Awesome reception.
Next steps:
🔹Clean up our inboxes
🔹Assign roles in Discord (50% done)
🔹Re-launch with more automation
🔹Add more ?s
We want this to be an ongoing mechanism for people to challenge themselves on industry questions (both cultural and technical), find weaknesses and work with each other to round out their knowledge base.
The goal is to entice community growth through quality, not quantity.
MegaETH is wartime Ethereum
We say what we mean, and we do what we say.
This is just the beginning.

📢 1:1 ALERT 📢
La Mouche is the enigmatic and feared underground boss of Monadia, a planet renowned for its vibrant, sprawling cities and treacherous underworld. His appearance is striking and otherworldly: he resembles a humanoid fly, with large multifaceted eyes that shimmer with an unsettling intelligence. His body is covered in a fine layer of iridescent exoskeleton, with two sets of translucent wings folded neatly against his back, capable of swift, silent flight when needed.
La Mouche's reputation on Monadia is one of both respect and fear. He rose to power through a combination of ruthless cunning and strategic alliances, manipulating the intricate web of criminal enterprises that thrive in the planet's shadows. His operations encompass a wide range of activities, from smuggling rare goods and orchestrating heists to running clandestine gambling rings and information brokering. He has eyes and ears everywhere, his network of informants and spies as vast as it is loyal.
Despite his fearsome reputation, La Mouche is known for his sharp intellect and strategic mind. He is a master manipulator, always several steps ahead of his rivals and the authorities. His conversations are laced with wit and subtle threats, and he enjoys playing mind games with those who dare to challenge him. His loyalty is fierce but hard-won, reserved only for those who prove themselves invaluable to his cause.
