Sei Community is rebuilding its blockchain from the bottom as much as hit 200,000 transactions per second with finality below 400 milliseconds. The challenge, known as Giga, just isn’t one improve however three separate ones working collectively: a brand new consensus layer, a brand new execution engine, and a brand new storage system. Sei Labs revealed the general public roadmap in late Might 2026, and components of it are already reside on mainnet.
For readers who know Sei solely as a quick, trading-focused Layer 1, Giga marks a bounce in ambition. The community’s earlier throughput sat within the 5,000 to 12,500 TPS vary. If Giga hits its goal, that might be a 40 to 50-fold enhance in uncooked capability, utilizing a metric Sei calls gigagas to measure computational throughput slightly than transaction depend alone.
What Is the Giga Improve, Precisely?
Giga is a multi-phase engineering program that touches three components of the blockchain: how validators agree on transactions, how these transactions get executed, and the way the ensuing information will get saved. Sei Labs describes it as a full rebuild slightly than a tuning move on the prevailing system. Full compatibility with the Ethereum Digital Machine (EVM) is preserved all through, so builders constructing on Sei don’t must rewrite their good contracts to learn from the modifications.
The three elements every have their very own title:
- Autobahn handles consensus, the method validators use to agree on the order of transactions.
- Ares rebuilds the execution consumer, the software program that truly runs transactions.
- Eidos rebuilds storage, the database layer that information and serves chain historical past.
How Does Autobahn Attain 200,000 TPS?
Most blockchains depend on a single block proposer at a time. One validator proposes a block, the community votes, and solely then does the subsequent validator get a flip. That sequential course of creates a bottleneck regardless of how briskly the {hardware} is.
Autobahn is a multi-proposer consensus protocol, that means a number of validators can suggest blocks on the similar time as an alternative of taking turns. Paired with asynchronous execution, which decouples transaction processing from the consensus layer so transactions haven’t got to attend for one another in strict sequence, that is the mechanism Sei Labs credit for the leap from 1000’s of TPS to a goal of over 200,000.
Sei has mentioned an inside, geographically distributed devnet has already demonstrated 5 gigagas of throughput and TPS above 200,000 below managed situations, although the reside mainnet has not but reached these figures and real-world efficiency might differ from benchmark outcomes.
What Modified With the Ares and Eidos Rollout?
Sei shipped the primary concrete items of Giga via its v6.6 mainnet improve in August 2026, which introduced Ares on-line because the default execution consumer and began the phased rollout of Eidos.
Earlier than this replace, Sei’s EVM state historical past shared a database with the remainder of the chain’s Cosmos SDK information. That created I/O competitors: a question wanting up outdated transaction historical past may decelerate reside transaction processing. Eidos separates EVM state into its personal devoted database, a change designed to cease historic queries from crowding out real-time execution.
In response to Sei’s engineering weblog, the brand new pruning course of constructed into this section minimize a cleanup move that used to take 8 to 18 minutes all the way down to roughly 5 minutes, and it retains nodes inside about 60 blocks of the chain tip as an alternative of drifting a whole lot of blocks behind.
The migration is designed to run with out taking the community offline. Previous and new storage methods function aspect by aspect, information strikes throughout in small batches block by block, and the swap is ruled by an on-chain vote and constructed to be reversible. Sei mentioned shadow nodes replayed actual mainnet visitors towards the brand new storage design earlier than it shipped, and block instances stayed largely unchanged throughout testing.
Extra elements of Eidos, together with a format known as FlatKV, a hashing construction known as LtHash, and new receipt storage, are scheduled for later phases slightly than transport suddenly. Autobahn, the consensus piece, remains to be in progress and has not but reached mainnet as an entire system.
How Does This Examine to Different Chains?
Context issues right here, since uncooked TPS numbers are straightforward to inflate and not using a reference level:
- Ethereum’s base layer processes roughly 15 to 30 TPS.
- Solana has a theoretical ceiling close to 65,000 TPS, although real-world throughput sometimes runs effectively beneath that.
- Sei’s present mainnet, utilizing its present Twin Turbo optimizations, already achieves sub-400ms block instances, near 30 instances quicker than Ethereum’s finality.
If Giga’s targets maintain up in manufacturing, Sei would sit in a throughput tier that few EVM-compatible Layer 1 chains have tried, although the hole between a managed devnet benchmark and sustained mainnet efficiency below actual load is the element price monitoring because the rollout continues via 2026.
The place Does the $SEI Token Stand Proper Now?
As of late August 2026, $SEI is buying and selling close to $0.046, with a market capitalization of roughly $308 million and a circulating provide of about 6.7 billion of the ten billion token most. The token has posted a 13.5% acquire over the trailing seven days however stays roughly 96% beneath its March 16, 2024 all-time excessive of $1.14. As a result of $SEI trades throughout dozens of exchanges, quoted costs range barely by platform and by the minute, so readers ought to verify a reside tracker for the precise present determine slightly than treating any single snapshot as fastened.
Tokenomics context issues alongside the value. Sei’s Complete Worth Locked fell sharply from a peak close to $626 million in mid-2025 to roughly $41.6 million as of an April 2026 studying, a sign of weak capital retention even because the technical roadmap has superior. A few third of the ten billion token provide stays locked below a multi-year vesting schedule, with month-to-month unlocks reported within the vary of 112 to 132 million $SEI as of mid-2026, an ongoing supply of sell-side provide that market watchers deal with as separate from the engineering progress itself.
What Comes Subsequent?
Sei Labs has not set a set completion date for Giga, as an alternative rolling out every element in phases and monitoring progress publicly at its milestone tracker. Two of the three subsystems, Ares and Eidos, have partially reached mainnet as of August 2026. Autobahn, the consensus rebuild accountable for the multi-proposer design on the middle of the 200,000 TPS goal, stays the most important piece nonetheless forward.
