Note that this is a FAQ meant to accompany the below Timeboost AIP that is proposed to the ArbitrumDAO for adoption on Arbitrum One and Arbitrum Nova. This FAQ is not meant to accompany the newly announced Timeboost specification for Timeboost with Espresso Systems’s Decentralized Sequencer design (which Offchain Labs has worked with Espresso to jointly develop). The intended audience for this FAQ are members of the public interested in learning about Centralized Timeboost, especially those who are ArbitrumDAO members.

Timeboost AIP Forum Post -

Constitutional AIP: Proposal to adopt Timeboost, a new transaction ordering policy

1. What’s an ELI5 on Timeboost?

2. As a typical user, will I notice any difference in my experience?

3. Where does the Timeboost income stream come from?

4. What is the difference between the two options above?

5. How can I participate in Timeboost directly?

6. How much estimated revenue will this drive to the DAO?

7. What is the goal of Timeboost?

8. Does it work with Orbit chains?

9. How does Timeboost affect Orbit chains that settle to Arbitrum One or Arbitrum Nova?

10. Does this vote passing automatically mean that all orbit chains will have timeboost implemented?

11. Does it mean we expect searchers to bid continuously in advance, expecting opportunities to happen 1 minute later, rather than “in real time” opportunities (I see something → I submit an arbitrage tx with priority)?

12. When it comes to the implementation and integration, are there any references to Fastlane?

13. Will the changes [the special rights being asked to be granted to the current sequencer operator] be made without community discussion or through on-chain voting?

14. Although Timeboost improves the fairness of the network, the complicated sorting mechanism may affect the transaction experience of some users. It is recommended that Timeboost be implemented with a clearer user interface that allows users to understand the logic of how their transactions are sorted, as well as an optional setting to adjust the sensitivity to the time factor. Are there efforts to address this?

15. Will there be a testnet for Timeboost?

16. What are the different variations of Timeboost?

17. Will Timeboost work with future decentralized Arbitrum sequencers?
