Sei Labs has completed the first full test of its Sei Giga architecture, recording about 63,200 requests per second and 1.33 billion gas per second during testing as the blockchain prepares for the next stages of its performance upgrade.
Sei Labs co-founder Jayendra Jog announced the test, saying engineers had completed the first full test of the new architecture. The reported results also showed consensus finalization times of 17.1 milliseconds at the 50th percentile and 38.6 milliseconds at the 99th percentile.
The results are part of Sei’s longer-term Giga development program, which is designed to rebuild the network’s execution, storage, and consensus layers. Sei has set a target of 5 gigagas per second and 200,000 transactions per second for the completed architecture.
Sei Giga Test Records 63,200 Requests Per Second
The first full test measured the Giga architecture’s performance under test conditions. According to the reported test dashboard, the system reached approximately:
| Metric | Reported Test Result |
| Requests per second | 63,200 |
| Gas per second | 1.33 billion |
| Consensus finality, p50 | 17.1 ms |
| Consensus finality, p99 | 38.6 ms |
| Long-term Giga target | 5 gigagas per second |

Sei described the test as demonstrating “unprecedented throughput and finality for an EVM chain.” The figures should be treated as test measurements rather than current mainnet performance.
That distinction matters because Sei Giga is still being rolled out in stages. The network’s existing mainnet is already receiving components of the new architecture, but the complete Giga design has not yet been deployed.
Giga Is Rebuilding Three Parts of Sei
Sei Giga is not a single software upgrade. It consists of three major development tracks covering execution, storage, and consensus, and it reflects an industry-wide focus among Layer-1 platforms to compete on raw throughput.
The execution component, called Ares, is designed to replace Sei’s previous execution path with a rebuilt engine optimized for higher throughput.
The storage component, Eidos, is designed to separate EVM history from the rest of Sei’s database infrastructure. Sei said the first phase of Eidos reached mainnet with the v6.6 release in August, beginning the migration of EVM state into its own database.
The third component focuses on consensus. Sei’s Giga roadmap includes changes intended to improve transaction ordering, execution, and data propagation so that consensus does not become a bottleneck as transaction throughput increases.
This means the latest test represents progress across the broader Giga architecture rather than a completed mainnet upgrade.
Ares and Eidos Have Already Reached Mainnet
Sei began putting parts of Giga into production with the v6.6 upgrade last August. According to Sei, Ares became the default execution path on mainnet, while the Eidos upgrade began separating EVM state from the existing database.
Sei also kept its previous execution engine as a fallback and reference implementation to compare results between the old and new execution paths.
The first phase of Eidos was designed to improve how the network handles historical data as transaction activity increases. Sei said the upgrade reduced a node cleanup process from roughly eight to 18 minutes to about five minutes in its measurements, while keeping nodes closer to the chain tip.
The consensus portion of Giga is still being developed. Sei’s roadmap describes it as a later stage of the broader architecture upgrade.
Sei Giga Moves Toward Production Testing
The completed test gives Sei Labs another data point as it continues testing the architecture before broader deployment.
The project’s roadmap calls for the three Giga workstreams to progress through multiple releases rather than arrive in a single network upgrade. Ares and Eidos are already running in some form on mainnet, while additional work remains on the consensus layer and later storage improvements.
For developers, the main question is whether the architecture can maintain the reported performance while handling the wider range of transactions and applications found on a live blockchain.
For Sei, the test also provides an early indication of whether its approach to rebuilding the EVM stack can deliver the performance improvements outlined in its Giga roadmap.
What Comes Next
Sei Labs is expected to continue testing the Giga architecture before moving additional components toward production deployment. The network still has to complete development of the consensus workstream and later stages of the storage and execution upgrades.
The latest results show that the Giga architecture has reached a full testing stage, but they do not mean Sei mainnet is currently processing the reported test throughput.
What This Means for You: Sei users do not need to take any action because of the latest test. Giga is being introduced in stages, with Ares and Eidos already beginning their mainnet rollout. The latest results give users and developers an early look at how the new architecture performs as Sei continues its upgrade.
