The inclusion of fee burning and potential integration of mev-boost are exciting advancements for Aztec’s block production. However, two key considerations merit further discussion:

  1. Mitigating Manipulation of Randomization: While Fernet’s randomized sequencer selection appears robust, I’m interested in understanding the specific mechanisms in place to prevent malicious actors from influencing the process. Are there cryptographic safeguards or economic disincentives to deter manipulation attempts?
  2. Security of Out-of-Protocol Proving: Utilizing an out-of-protocol proving system like Sidecar offers flexibility, but raises security concerns. Could you elaborate on the measures taken to ensure the integrity and confidentiality of proofs generated outside the core protocol? Additionally, how are potential vulnerabilities like front-running or denial-of-service attacks addressed within this setup?

I have some questions:
Who can serve as provers in the Aztec Network?
What is the purpose of comparing and ranking the hashed values of other sequencers’ public keys and RANDAO values?
How is the highest ranking proposal determined and what becomes of it?
Is there any debate or research on whether this phase is necessary or not?

Hello Cooper!
How do Aztec full nodes verify and apply blocks to their local view of the state?
How do Aztec Sequencers choose provers and coordinate state transitions in the network?
Can anyone participate in Aztec Sequencers, and what protocol is planned to be implemented for participation?
Can participants other than full nodes become Aztec Provers, and what are some examples of these participants?

Hey, awesome read!
Can you explain the mechanisms Aztec proposes to implement in order to mitigate the risks associated with MEV (Maximal Extractable Value) within its network, and how these mechanisms differ from those employed in Ethereum?

Hey, have some questions there:
How does the Fernet protocol ensure fair and randomized leader selection among sequencers, and what measures are in place to prevent manipulation or centralization of power within the Aztec Network?
Can you elaborate on the role of validating light nodes within the Aztec Network and how they contribute to maintaining network integrity while processing block headers and validating proofs?

Hi Cooper,
Thanks for the article. I’d really like to know minimum and recommended requirements for the validating light nodes. Hope requested storage will be much lower as there’s no need to store the full state.

What is the expectation about who will post the prover commitment? It would seem that the sequencer would be the natural provider of the commitment, as it is a single commitment for the full proof tree and the actual proving may and presumably should be split over multiple provers, while still allowing the sequencer to distribute the proof tree creation in a flexible way. Is this the main concept?

Isn’t keeping the tnxs private a direct contradiction to the “decentralised” goal of cryptocurrency and web3 it self? And read it and i think making it public would not have any adverse consequences. Gas fee burn decision should be made carefully, I understand the need to scale up transactions speed and chain itself. But we also need to put the end user into consideration. Great read regardless!
