Layer 2 scaling answer Arbitrum launched Timeboost on its Arbitrum One community, describing it as a brand new transaction ordering mechanism supposed to handle frequent points equivalent to community congestion, transaction spam, and latency-based competitors.

At present, Arbitrum follows a “First-Come, First-Serve” (FCFS) transaction ordering mannequin, which supplies a typically constructive consumer expertise and protects in opposition to sure sorts of dangerous miner extractable worth (MEV). Nonetheless, in response to the group, a lot of the MEV exercise on the chain includes searchers investing closely in quicker {hardware} or spamming transactions to realize a aggressive edge in latency-sensitive eventualities—conduct that contributes to pointless community pressure.

Timeboost is designed in its place ordering strategy that maintains some great benefits of FCFS whereas additionally introducing a mechanism for lowering latency-related competitors. It does this by implementing a sealed-bid, second-price public sale system tied to an “specific lane” inside the Arbitrum sequencer. Transactions submitted via this specific lane are sequenced immediately, whereas others face a small, predefined delay—presently set at 200 milliseconds. Public sale winners acquire unique, non permanent entry to the specific lane, permitting them to keep away from the delay and have their transactions prioritized.

The introduction of Timeboost is predicted to permit ecosystem members—particularly chain operators and superior customers equivalent to searchers—to have interaction in MEV seize in a extra structured, much less disruptive means. As a substitute of investing in {hardware} or partaking in spam to compete, members can allocate assets towards bidding for transaction precedence. For chain homeowners, this will likely additionally introduce a possible income stream derived from the MEV already being generated on their platforms.

Importantly, Timeboost is an non-compulsory function that may be adopted by Arbitrum chains with both centralized or decentralized sequencer fashions. Whereas the complete decentralized design remains to be in improvement, the present centralized implementation is publicly accessible and has been proposed to the Arbitrum DAO to permit earlier deployment. The platform emphasizes that even with Timeboost enabled, the general block time on Arbitrum chains will stay quick—persevering with at 250 milliseconds.

Timeboost Defined: Goal And Implementation

Timeboost is described as a transaction ordering mechanism utilized by Arbitrum chains. It establishes the algorithm that sequencers should comply with when organizing user-submitted transactions. Whereas the present system operates underneath a FCFS mannequin, Timeboost introduces modifications supposed to protect a lot of FCFS’s benefits whereas addressing a few of its operational inefficiencies. Within the close to time period, the system will function via a single sequencer, although assist for decentralized sequencers implementing Timeboost guidelines is deliberate.

The sequencer’s core perform on an Arbitrum chain is to obtain legitimate transactions, organize them based mostly on the transaction ordering coverage, after which distribute the finalized order via a reside feed and in compressed kind to the chain’s information availability layer. Timeboost builds on this course of by integrating three key components. First, it introduces an “specific lane” that allows qualifying transactions to be processed instantly upon arrival. Second, it makes use of an off-chain public sale—carried out by an autonomous system—to find out which participant controls the specific lane throughout an outlined time interval. Lastly, a wise contract deployed on-chain information the public sale outcomes and manages the distribution of proceeds, appearing because the authoritative supply of reality.

The public sale cycle is structured round a default 60-second spherical. Transactions not submitted via the specific lane face an intentional delay of 200 milliseconds to their timestamp, which can outcome of their inclusion within the subsequent block. This synthetic delay, mixed with the continued 250-millisecond block time, ensures the system stays responsive whereas enabling extra environment friendly transaction ordering.

Considered one of Timeboost’s targets is to keep up a user-friendly expertise, which Arbitrum chains are identified for, whereas resolving limitations of pure FCFS ordering. The system doesn’t grant public sale winners management over transaction visibility or block ordering—public sale winners solely acquire a short lived benefit in transaction processing, not privileged perception into the mempool. As a result of the mempool stays non-public, the dangers related to front-running and sandwich assaults are nonetheless mitigated.

Timeboost can be framed as a means to enhance community effectivity and introduce a novel worth seize mechanism. As a substitute of counting on {hardware} benefits or spamming to realize transaction precedence—a conduct that always results in community congestion—members can now bid for time-based benefits. This shift is predicted to cut back MEV-driven community spam and redirect competitors towards the public sale course of.

For chain operators, Timeboost gives potential financial advantages. Proceeds from the auctions may be collected in native gasoline tokens and redirected to assist functions, reward customers, or fund improvement. This introduces a brand new technique to align chain exercise with ecosystem development.

Timeboost is fully non-compulsory and may be enabled on the discretion of particular person Arbitrum chains. Chains can proceed working usually with out it, however those who decide in can customise its configuration to go well with particular use circumstances.

The influence of Timeboost varies by consumer group. For on a regular basis customers, the adjustments are minimal—non-express lane transactions might expertise a slight enhance in processing time, as much as roughly 450 milliseconds, however protections in opposition to malicious MEV behaviors stay intact because of the usage of a non-public mempool. For chain homeowners, the system supplies a possible income stream and a brand new mechanism to boost token utility. And for classy on-chain members, equivalent to arbitrageurs and searchers, Timeboost opens the door to various methods—equivalent to shopping for specific lane entry or monetizing unused slots—that would show more cost effective than earlier MEV techniques reliant on infrastructure or pace alone.
