Engineering Talent Moves In-House@Sei_Labs has acquired @bilinearlabs, bringing the firm's Rust-based engineering talent and data analytics capabilities directly into the $SEI ecosystem. The Bilinear team is transitioning into core development roles focused on Sei Network and the upcoming Sei Giga scaling initiative, deepening the in-house technical bench at a critical moment for the protocol.
The move follows Bilinear's track record of delivering real-time financial insights and on-chain intelligence for high-velocity decentralized markets, a profile that fits squarely with Sei's performance-first positioning in DeFi infrastructure.
What Is Sei Giga and Why Does It Matter?Sei Giga is @Sei_Labs' most ambitious technical undertaking to date. The initiative targets over 50x throughput, 70x faster block production, and 40x execution efficiency, with the broader goal of making Sei the first multi-proposer EVM Layer 1. It leverages parallel block proposals to solve bottlenecks, scaling the EVM with innovations across data availability, consensus, execution, and storage.
Key targets include 5 gigagas of throughput at roughly 200,000 transactions per second, alongside sub-400ms finality for low-latency, high-speed applications. Achieving that throughput would deliver execution speeds 50 times faster than any other mainnet chain, comparable to Web2-level transaction performance.
Advanced features including Autobahn consensus, a multi-proposer architecture, and the 5 gigagas throughput target are currently in development. Sei Labs has already achieved 5 gigagas of throughput in an internal devnet using Autobahn, a new consensus protocol designed for high throughput and low latency in globally distributed validator networks.
Bringing Bilinear's engineering resources in-house signals that Sei Labs is consolidating specialist talent rather than relying on external contributors as Giga moves closer to production. For the $SEI ecosystem, the acquisition adds depth on the data and systems side at a point when the protocol's technical roadmap is at its most complex.

Sei Labs uvedla, že nový storage engine FlatKV v interním 24hodinovém testu dosáhl průměru 205 913 TPS, tedy 13,7× více než současný MemIAVL. FlatKV je součástí upgradu Giga.
FlatKV Clears 200,000 TPS in Internal Testing@Sei_Labs has published benchmark results showing its new FlatKV storage engine averaged 205,913 transactions per second across a 24-hour test window. That figure stands 13.7 times above the roughly 15,000 TPS recorded by @SeiNetwork's current MemIAVL store under the same conditions, according to the team.
FlatKV is part of Eidos, the storage component of Sei's broader Giga upgrade program. Eidos is set to replace the existing structure for EVM state with FlatKV, a flat key-value storage system where an individual state change requires a single write. Verification will be handled using LtHash, or lattice hashing, which maintains a running fingerprint of the state. Under the design described by Sei, LtHash can update that fingerprint in constant time when state changes, removing the need to recalculate a path of hashes through a Merkle tree.
Where Giga Stands on Mainnet The first phase of Eidos reached Sei mainnet with the v6.6 release in August 2026, with EVM state beginning to move into its own dedicated database. That initial release also shipped a rebuilt pruning path, reducing a cleanup pass that used to take 8 to 18 minutes down to about five, and keeping nodes within 60 blocks of the chain tip.
The larger components of Eidos, including FlatKV with its lattice hash, the LittDB-backed receipt store, and the off-node archive, will arrive in subsequent releases. @Sei_Labs has the new store slated for a later release, where it replaces the Merkle tree for EVM state.
The upgrade is the storage component of a three-part architecture overhaul that also includes Autobahn for consensus and Ares for transaction execution. Sei Labs released its Giga whitepaper with a design targeting 200,000 transactions per second, 5 gigagas of throughput, and finality below 400 milliseconds. The migration is designed to run while Sei remains online, with existing and new storage systems operating alongside each other.
Sei's internal testing has demonstrated more than 200,000 TPS under controlled conditions, though those results do not represent sustained mainnet performance. The FlatKV benchmark adds further weight to the storage case, but the full Giga stack, including the Autobahn consensus layer, has yet to reach mainnet.

The pruning improvements are already measurable. Node stability has also improved:
All three tracks are being rolled out in stages, with the chain continuing to produce blocks throughout.
What FlatKV and Lattice Hashing Change Most blockchains verify state using a Merkle tree, a structure where a single change forces the recomputation of every hash above it in the tree.
In practical terms, This design keeps verification costs flat even as the chain grows.

Sei Labs: Ares and Eidos, the first components of the Giga Upgrade, will go live in Sei 6.6
Sei spustil postupný upgrade Eidos, který přestavuje ukládání on-chain dat a má podpořit síťový cíl 200 000 TPS. Migrace běží na mainnetu bez odstavení sítě.
Sei has begun rolling out its Eidos storage upgrade, rebuilding how the layer-1 network stores and verifies on-chain data as its Giga roadmap targets throughput of 200,000 transactions per second.
Summary
Sei has begun the phased rollout of Eidos through its v6.6 mainnet upgrade. Eidos is rebuilding the network’s storage architecture as Giga targets 200,000 TPS. EVM state is being separated into a dedicated database, while FlatKV and LtHash are planned for later stages. The migration is designed to run while Sei remains online, with existing and new storage systems operating alongside each other. Sei said in an Aug. 12 technical update that Eidos is designed to remove storage constraints that could prevent the network’s execution layer from operating at the speeds planned under Giga. The upgrade is the storage component of a three-part architecture overhaul that also includes Autobahn for consensus and Ares for transaction execution.
The first Eidos components have already reached mainnet through Sei v6.6, though the full storage system is being introduced in stages. EVM state has started moving into a dedicated database, while FlatKV, LtHash, new receipt storage and off-node archival systems are scheduled for subsequent releases.
Sei Eidos upgrade changes how state is stored At the center of Eidos is a change to the way Sei plans to maintain and verify Ethereum Virtual Machine state.
Sei said traditional Merkle trees require nodes to recalculate multiple hashes when a value changes because each update alters the chain of hashes leading to the tree’s root. As the amount of stored data increases, individual state changes can therefore require additional database work.
Eidos is set to replace that structure for EVM state with FlatKV, a flat key-value storage system where an individual state change requires a single write. Verification will be handled using LtHash, or lattice hashing, which maintains a running fingerprint of the state.
Under the design described by Sei, LtHash can update that fingerprint in constant time when state changes. Instead of recalculating a path of hashes through a Merkle tree, a node removes the contribution of the old value and adds the new one, leaving the amount of work per update unchanged as the state expands.
The technical change is tied directly to the performance targets outlined for Giga. As crypto.news reported in May 2025, Sei Labs released its Giga whitepaper with a design targeting 200,000 transactions per second, 5 gigagas of throughput and finality below 400 milliseconds.
At that throughput, Sei said the network would also have to write hundreds of thousands of database entries every second. Faster transaction execution would therefore provide limited benefit if the storage layer could not process state changes and transaction history at a comparable rate.
EVM data is moving into a separate database Another part of Eidos separates EVM state from other data handled by Sei nodes.
Before the change, Sei said EVM state shared a database with other information on the chain. The new architecture gives EVM state its own dedicated store, preventing historical queries from competing directly with live transaction processing and reducing database work imposed on non-EVM modules.
The split started reaching mainnet in the v6.6 release during August. Sei also introduced a rebuilt pruning path for removing data that nodes no longer need to keep in active storage.
According to the network, the pruning changes reduced one cleanup process from between eight and 18 minutes to roughly five minutes during testing and operation. Nodes that could previously fall hundreds of blocks behind the chain tip remained within about 60 blocks after the change, Sei said.
Blocks and transaction receipts are also being assigned a separate storage engine called LittDB. Sei described blocks and receipts as data that is written once, repeatedly read, and eventually archived, making their storage requirements different from frequently updated account and contract state.
Internal benchmarks cited by Sei put LittDB write throughput above one gigabyte per second while handling about 55,000 point reads per second. A new receipt store sustained more than 150,000 writes per second during multi-hour benchmark tests that included garbage collection. Sei cautioned that the figure measures the storage engine and should not be treated as blockchain transaction throughput.
Older history will move away from active nodes Eidos also changes how much historical information individual nodes are expected to keep locally.
Sei said frequently accessed state and recent chain history will remain on fast local storage, while older historical records will move to archival systems built for capacity. Explorers, indexers and users auditing historical transactions will still be able to retrieve the archived information, according to the network.
Reducing the amount of old data kept on active nodes is intended to prevent historical queries from consuming resources needed for current transactions. Sei said rising storage requirements can otherwise force operators to use faster and more expensive hardware as network throughput increases.
The infrastructure work follows earlier efforts to increase access to Sei’s EVM ecosystem. MetaMask added native Sei support in August 2025, allowing users to access Sei-based applications, swap assets and bridge tokens directly through the wallet. At the time, Sei was processing more than 4.2 million daily transactions and had more than 11 million monthly active users, according to figures cited in the report.
A separate distribution agreement announced in December 2025 called for Xiaomi to pre-install a Sei wallet on new smartphones sold outside mainland China and the United States. The companies also planned support for stablecoin payments using assets such as USDC, with initial payment deployments planned for Hong Kong and the European Union.
Eidos migration runs while Sei remains online For node operators, Sei is carrying out the storage migration without stopping the blockchain.
The network said existing and replacement storage systems will operate alongside one another while data moves in batches from block to block. The rollout is controlled through governance and has been designed with a rollback process if problems emerge.
Ahead of deployment, shadow nodes replayed mainnet traffic against the new storage systems while integrity hashes were continuously checked, according to Sei. Testing showed block times remained largely unchanged while migration processes operated in the background.
Eidos is the third storage rebuild undertaken by Sei. The network previously replaced its original Cosmos storage architecture with SeiDB, followed by the state-store separation now being introduced on mainnet. FlatKV, LittDB and the off-node archival system will form the next stage as they arrive through later releases.
Users and application developers do not need to take action during the migration, according to Sei, with balances, smart contracts, historical records and existing RPC endpoints remaining available. Node operators have been given a migration guide covering configuration flags and the documented rollback process for the new storage system.
Sei spouští Eidos, upgrade storage, který běží přímo v provozu sítě a postupně přesouvá stav EVM do vlastní databáze. Cílem je, aby storage držela krok s Giga a 200 000 transakcemi za sekundu.
TL;DR: Every blockchain node has two jobs: compute what happens next on the chain, and store what has already happened. Storage is a critical bottleneck for all blockchains as they attempt to scale. If storage can't keep pace with the rate at which new transactions are executing, huge problems can occur. Eidos is the upgrade that will take Sei’s storage layer to Giga speed.
What is Sei's Giga Upgrade?Giga is the series of upgrades designed to dramatically improve the Sei blockchain, making it much faster and giving it next-generation features, to make it the optimal onchain environment for trading.
Giga is composed of three tracks of upgrades, one for each layer of the chain. A series of consensus upgrades, beginning with Autobahn, will rebuild how validators agree on what’s true. The Ares Upgrade rebuilds execution, the part that actually runs transactions. Eidos rebuilds storage, the critical part of the chain that stores all the transactions that have happened and allows users and apps to query this data.
Every transaction that a blockchain executes has to be written down, and if the notebook can’t keep up with the pen, the pen’s speed is irrelevant. A chain that executes at 5 gigagas per second while writing to a database designed for an earlier era is a sports car on bicycle wheels.
Eidos exists to fix that. It introduces a new database structure, and implements it onto the chain live, while the blockchain keeps running.
Understanding blockchain storageA blockchain stores multiple things. First, the live state of the network: every account balance, every deployed contract, every value those contracts keep in their storage. Secondly, the historical state: every block ever produced, every transaction inside those blocks, and every receipt recording what each transaction did.
This storage is essential for every aspect of using a blockchain. When you check a balance in your wallet, a node looks it up in state. When a trading app draws a price chart or a block explorer shows last week’s transfers, nodes are reading history.
Each transaction changes some state and appends to history, so a chain processing 200,000 transactions per second is also writing hundreds of thousands of database entries per second, every second, forever.
When a blockchain’s storage can’t keep pace with execution, often the only way to survive is to throw money at the problem. Larger, faster, and more expensive disks can compensate for a slow data layer. But as throughput grows and hardware requirements rise, the cost of running a node swells until most operators can’t afford to run them. Queries about last month slow down the processing of live transactions. Eventually the execution layer, however fast, sits idle waiting for the database to catch up.
Why Sei Giga needs better data validationA blockchain database can’t just store data; it has to be able to verify the data hasn’t been tampered with. The classic tool for this is a Merkle tree: every piece of state gets hashed, hashes get paired and hashed again, and again, until a single root hash fingerprints the entire state of the chain. Anyone can check a value against that root and know it’s genuine.
Because the values are chained together in a tree, updating one account means recomputing every hash on the path from that account up to the root, and each of those recomputations is another disk write. Even worse, the more data stored by the chain, the more expensive each individual update becomes. Because of this, at 200,000 TPS, Merkle trees stop being feasible.
Eidos retires the Merkle tree for Sei’s EVM state. Its replacement, a store called FlatKV, keeps state in a flat key-value layout where one change is one write. A lattice hash (LtHash) maintains a running fingerprint of the entire state that updates in constant time per change, without cascading recomputation. The network keeps its ability to verify everything.
Instead of arranging every value in a tree and hashing a path to the top, the node keeps one fingerprint that individual changes can be added to or subtracted from directly. Update a balance and the node subtracts the old value’s contribution and adds the new one, a fixed amount of work no matter how large the state grows.
What else changes under the hoodRemoving the Merkle tree is the core architectural move, but Eidos is a rebuild of the whole storage stack.
Live state gets its own databaseToday, EVM state shares a single database with everything else on the chain. Under Eidos it moves into its own dedicated store. Reads of history stop competing with live transaction processing, and the chain’s non-EVM modules stop paying write costs for EVM data they never touch. The EVM state split began rolling out in v6.6.
Each workload gets the right engineEvery transaction onchain produces a receipt: a record of what happened, what it cost, and which events it emitted. Each time a wallet shows the confirmation checkmark, an app verifies your swap landed, or a dashboard tallies yesterday’s volume, something is reading receipts. At Giga’s target throughput, Sei would produce 200,000 of them per second.
Blocks and receipts have a peculiar shape as data: written once, never updated, read constantly, and eventually archived. Sei’s new block and receipt stores run on LittDB, an open-source embedded database originally developed by a Sei Labs engineer for exactly this write-once pattern, now integrated into Sei’s node software. LittDB has been clocked at over a gigabyte per second of write throughput while serving roughly 55,000 point reads per second at the same time, and the new receipt store sustained more than 150,000 writes per second, flat, across multi-hour benchmark runs that included garbage collection. That number is a benchmark of the storage engine itself, not a chain TPS figure, so it isn’t comparable to Giga’s 200,000 TPS target.
Old history leaves the nodeWhile the state and recent history a node actually touches stay local, on the fastest storage, older history moves off the node entirely, into archival storage built for capacity rather than speed. Full history stays available to anyone who asks: explorers, indexers, and anyone auditing the chain’s past read from the archive, while the nodes doing real-time work carry only what real-time work needs.
Upgrading storage while the chain stays liveSei already has a live database which holds the entire live state of the network, and the chain on top of it produces a block roughly every 400 milliseconds, around the clock.
The easiest option would be to halt the chain, snapshot everything, migrate, and relaunch. Or ask every node operator to throw away their data and rebuild from scratch. Both approaches are common, and respected networks have used them.
Eidos takes the harder route: the migration runs inside the node while the chain keeps producing blocks. Data moves across in small batches, block by block, with the old and new stores running side by side until the new one has proven itself, and the whole rollout is switched on by governance and reversible by design. It’s also checked at every step: shadow nodes replayed real mainnet traffic against the new stores before rollout, integrity hashes are audited continuously, and in testing, block times stayed essentially unchanged while the migration ran underneath.
The first phase of Eidos reached Sei mainnet with the v6.6 release in August 2026. EVM state began moving into its own database, and a rebuilt pruning path shipped alongside it. That pruning fix is already measurable for operators, reducing a cleanup pass that used to take 8 to 18 minutes down to about five, and keeping nodes within 60 blocks of the chain tip where they used to drift hundreds behind. The larger parts of the Eidos upgrade, such as FlatKV with its lattice hash, the LittDB-backed receipt store, the off-node archive, will arrive in subsequent releases.
What users need to knowUsers and app developers don't have to take any actions. Balances, contracts, and history carry over untouched. Existing RPC endpoints can be used as normal.
If you run a node, the migration guide for RPC operators is already public in the sei-chain repository, with the config flags and the rollback path documented. Longer-term, node operators will be able to run leaner machines. This has long term benefits for the chain, as it will become cheaper to become a Sei node operator.
The third rebuildEidos is the third time Sei has rebuilt its storage layer, and every rebuild has shipped into a network that was already live. SeiDB replaced the original Cosmos storage stack. The state-store split now on mainnet carved EVM data out into its own database. FlatKV, LittDB, and the off-node archive are the third generation, arriving phase by phase.
Giga’s target is 200,000 transactions per second. Eidos will make sure that Sei's storage smoothly keeps pace.

Chainlink Data Streams jsou nyní na síti Sei Network a přinášejí 24/7 cenová data pro americké akcie a ETF. Decentralizované aplikace tak mohou na Sei obchodovat tokenizované akcie bez uzavření trhu.
Round-the-Clock Equity Data Comes to Sei@Chainlink U.S. Equities Streams are now live on @SeiNetwork, delivering institutional-grade price data for the $80 trillion global stock market to a blockchain environment that never closes. Chainlink Data Streams has been integrated into Sei Network as its preferred oracle solution, bringing low-latency, high-frequency market data to power real-time DeFi and trading applications.
The practical effect is significant. Decentralized venues on Sei can now bypass the opening and closing hours of legacy exchanges, settling tokenized equity positions around the clock with sub-second finality. Sei, a layer-1 blockchain featuring EVM compatibility and parallelized execution, will use Chainlink Data Streams for sub-second price latency, high data accuracy, and liquidity-weighted bid-ask spreads.
Chainlink has launched Data Streams for major U.S. equities and ETFs including SPY, CRCL, QQQ, NVDA, AAPL, and MSFT, with additional markets and asset classes on the horizon. The infrastructure has helped enable more than $25 trillion in on-chain transaction volume for leading DeFi applications.
Monaco Trading Builds High-Frequency Equity Markets on $SEI@MonacoTrading is among the first protocols to put these $LINK-powered streams to work, using them to build high-frequency markets for primary stock tickers directly on the $SEI execution layer. Monaco is the high-frequency trading layer designed to establish a decentralized Wall Street on the Sei network. The protocol achieves microsecond execution coupled with Sei's 400-millisecond settlement, a 200,000x improvement over traditional T+1 settlement cycles.
Chainlink U.S. Equities Streams are already being leveraged by other top protocols, including Lighter, BitMEX, ApeX, HelloTrade, Decibel, Opinion Labs, and Orderly Network. The arrival of the streams on Sei broadens that ecosystem further, giving builders on the network access to the same pricing infrastructure used by established derivatives venues.
Chainlink's recent partnership with the U.S. Department of Commerce will also bring Bureau of Economic Analysis data on-chain to Sei Network, including Real GDP, PCE Price Index, and domestic purchasing metrics. That layer of macroeconomic data, combined with live equity feeds, positions Sei as one of the more comprehensively wired blockchains for finance-focused applications.

Sei spustil na mainnetu v6.6, největší upgrade od zavedení podpory EVM. Ares je nyní výchozí cesta pro transakce a podle Sei Labs má zhruba 10× vyšší propustnost.
Sei (@SeiNetwork) v6.6 is live as of block 224,201,091, making it the network's largest upgrade since EVM support launched in May 2024. The release bundles nearly 400 pull requests and, more significantly, marks the first time Sei Giga components have touched mainnet.
Ares and Eidos: The First Giga Components Go Live The two headline changes in v6.6 each target a different layer of the stack. The release introduces the first pieces of two of the three major Giga upgrades: Eidos, a new storage layer that will begin moving the chain's history into its own database, and Ares, a rebuilt execution engine that will become the default path for running transactions.
Ares is now the default execution path on every upgraded node, and according to @Sei_Labs it delivers roughly 10x the throughput of the previous setup. With v6.6, Giga stops being a roadmap and starts being something running on mainnet: Eidos has begun moving history into storage built for scale, and Ares is now the default execution path.
The Eidos change addresses a structural inefficiency that has been present since EVM support arrived. Until now, Sei's EVM history and Cosmos state have shared the same database, meaning history reads compete with live activity and modules unrelated to the EVM still pay write costs for EVM data. Eidos separates them. EVM history will move into its own dedicated database, so reading old history stops competing with transactions happening in real time.
Security Patches and Validator Improvements Beyond the Giga components, v6.6 patches more than 30 security issues spanning denial-of-service exposure and supply-chain hardening. Validator operations also get practical improvements, including faster pruning and retuned consensus timing to smooth out day-to-day operations.
Both Ares and Eidos are only the first step and will continue across future releases. v6.6 is a large release, with many fixes unrelated to Sei Giga. The third pillar of the Giga programme, a new Autobahn consensus mechanism, is not included in this release. Consensus, the third major part of the Giga upgrade, will only go live later.
The longer-term ambitions remain substantial. The full Giga upgrade targets over 200,000 transactions per second and sub-400 millisecond finality through the new Autobahn consensus mechanism and asynchronous parallel execution. Those figures remain forward-looking benchmarks rather than live metrics, but v6.6 represents the first concrete step toward them on a live network.
$SEI holders have been following Giga's progress since it was first outlined in late 2024, and the mainnet rollout is now underway in earnest.

Sei Network se chystá integrovat Dinari a nabídnout první self-custodial portfolio amerických akcií na své vrstvě 1. Přístup má zahrnout 724 tokenizovaných akcií, včetně všech firem z S&P 500, se zúčtováním v USDC.
Sei Network Prepares to Launch Tokenized U.S. Equity Trading@SeiNetwork is gearing up to integrate @DinariGlobal, a move that would bring the first self-custodial U.S. equity portfolio to the high-speed Layer 1 blockchain. The upcoming launch is set to give investors access to 724 tokenized stocks, including every company in the S&P 500, settled directly in @Circle's $USDC.
Dinari's dShares platform enables tokenized U.S. stocks and ETFs that preserve the rights and protections of traditional securities, including guaranteed redemption at the National Best Bid and Offer, cash dividends, and automated corporate actions. As an SEC-registered transfer agent, Dinari has built infrastructure that enables broker-dealers, exchanges, fintechs, and other regulated financial institutions to issue, custody, trade, and service tokenized securities within the existing regulatory framework.
The integration bridges what proponents describe as the $75 trillion U.S. stock market with Sei's high-performance infrastructure. Sei offers sub-400ms finality, a parallelized EVM, and a modular architecture that supports continuous optimization. That speed makes T+0 settlement and 24/7 liquidity operationally viable for both domestic and international participants, something traditional equity markets, which close on weekends and settle on a T+1 cycle, have long been unable to offer.
A Broader Push to Put U.S. Equities OnchainThe Sei integration is part of a broader expansion by Dinari across multiple blockchain environments. Bitcoin.com announced a partnership with Dinari in May 2026 to offer tokenized U.S. equities to its ecosystem, giving users of the Bitcoin.com Wallet access to over 300 tokenized U.S. equities and ETFs. Dinari and tZERO also joined forces to create a turnkey platform for tokenized U.S. equities for broker-dealers, packaging issuance, trading, custody, settlement, and shareholder servicing into one regulated framework.
On August 4, 2026, Dinari announced the expansion of its U.S. operations to financial institutions via its broker-dealer subsidiary Dinari Securities LLC, allowing broker-dealers, banks, fintechs, and wealth platforms to offer tokenized securities products and services to both retail and institutional customers.
The regulatory backdrop is also shifting in Dinari's favor. Dinari recently joined the Blockchain Association, the leading trade association representing the digital asset industry in Washington, D.C., to contribute its expertise as policymakers continue shaping the future of tokenized securities. The Sei Network integration, once live, would represent one of the most direct on-ramps yet for crypto-native investors seeking exposure to mainstream U.S. equities without leaving self-custody.

Sei 6.6 uvede první část Giga upgradu na mainnetu: Eidos začne přesouvat historii do vlastní databáze a Ares se stane výchozí cestou pro zpracování transakcí.
TL;DR: the proposal for Sei 6.6 is live, and it will be the release where Sei Giga starts touching mainnet. 6.6 will introduce the first pieces of two of the three major Giga upgrades: Eidos, a new storage layer that will begin moving the chain’s history into its own database, and Ares, a rebuilt execution engine that will become the default path for running transactions.
What the two upgrades actually areA blockchain has three key components. It agrees on the order of transactions (consensus), it runs them (execution), and it keeps a permanent record of everything it has ever done (storage). Sei 6.6 is where two of those three jobs will start becoming their Giga versions.
Eidos will upgrade Sei’s storage layer, and Ares will upgrade Sei’s execution client to the Giga executor. Both need to keep pace with the 200,000 TPS that Sei Giga is targeting.
These upgrades will begin in 6.6 and continue in future releases. Consensus, the third major part of the Giga Upgrade, will only go live later.
How Eidos changes storageEidos will begin moving the chain’s history out of a shared database and into one built for the job. In 6.6, the historical state migration will start.
Until now, Sei’s EVM history and Cosmos state have lived in the same database. That means history reads compete with live activity, and modules that have nothing to do with the EVM still pay write costs for EVM data.
Eidos will separate them. EVM history will move into its own dedicated database, so reading old history stops competing with the transactions happening right now, and non-EVM parts of the chain stop carrying the write cost of EVM data they never touch.
How Ares changes executionAres is a rebuilt execution client, and in 6.6 it will become the default execution path on mainnet. Every upgraded node will run it unless it opts out.
Ares is a different design from what came before. Where the old v2 engine used a Go-native path, Ares is built on an EVMC backend with evmone as the interpreter, and it runs its own state and cache stack.
The old engine will keep two roles.
First, it will act as a per-transaction fallback. When Ares hits something it can’t handle cleanly, that single transaction will rerun on the v2 engine instead of the new engine guessing at the result. Nothing gets dropped or approximated. The fallback catches the edge case and the block moves on.
Second, a full v2 node will run on every network as a live reference. It will process the same blocks as the new engine and compare results block by block. If the two ever disagree, it will page the on-call team. That means a mismatch between the old and new execution paths becomes an alert a human sees, not a silent divergence that surfaces later as a bug.
What comes next6.6 will be the release where Giga stops being a roadmap and starts being something running on mainnet. Eidos will have begun moving history into storage built for scale, and Ares will be the default execution path. Both are only the first step, and both continue across the releases that follow.
6.6 is a massive release, with many fixes that are unrelated to Sei Giga. The full list is in the 6.6 proposal.
Sei Labs předložila návrh SIP-5, který má umožnit stávajícím účtům na Sei přidat kvantově odolný klíč bez změny adresy ani zůstatku. Cílem je připravit síť na budoucí hrozbu kvantových počítačů.
TL;DR: Sei Labs has shared a new proposal, SIP-5, that lays out how existing accounts can stay safe once quantum computers are powerful enough to break today’s cryptography. The plan lets users keep current addresses and balances, allowing you to add a quantum-resistant key when you are ready, and does it all well before any real threat exists.
What is SIP-5Every EVM blockchain today rests on the same kind of cryptography. It works because the math behind it is impossible for classical computers to reverse. A powerful enough quantum computer would change that. In theory, it could take a public key that has already been seen onchain and work backward to the private key that controls the account.
That machine does not exist yet, but many experts believe the timeline for one is accelerating. The point of SIP-5 is to introduce a solution well before a threat exists.
SIP-5 is Sei Lab’s proposed path for upgrading existing accounts to quantum-resistant security without breaking anything people already rely on. It is a proposal, shared openly, so the ecosystem can look at it and decide together how to move forward.
Why this is the right time to talk about itQuantum computers capable of breaking today’s signatures are not here. Waiting until the threat is imminent, however, means designing the fix under pressure. Rushing such an upgrade could introduce many implementation risks.
SIP-5 takes the opposite stance. It proposes adding the quantum-resistant option far in advance, so the solution is in place well before the threat exists. And, if the timeline moves faster than anyone expects, the network is already prepared.
What it would mean for account holders on SeiYour address will stay the same. Your balance will stay the same, as will your transaction history, approvals, and the contracts you interact with. SIP-5 is built specifically to avoid forcing users to abandon their old accounts.
Under SIP-5, when you are ready, you attach a new quantum-resistant key to your existing account. From that point on, the account would be protected by the new key. Under the proposal, you would also choose your own pace. You can move early if you want the extra security sooner, or you can wait.
The real trade-offsThis approach has two trade-offs, which is why Sei Labs is not proposing it as something to immediately be implemented.
The first is that there is a future cutoff point, set by governance if and when the plan is adopted, after which an account can only continue to send transactions if it has already added its quantum-resistant key.
An account that never adds one would still be able to receive funds, but it would no longer be able to send. That is the practical reason the option is being introduced so far ahead of time. The window to prepare is meant to be long and unhurried, which is only possible if the conversation starts now.
The second trade-off is that upgrading to post-quantum signatures will slow the performance of every EVM blockchain. Today’s post-quantum signature schemes are many times larger than existing signature schemes. That means bigger messages to broadcast across the network, so fewer can be sent at once.
To solve for these tradeoffs Sei Labs is simultaneously proposing the emergency solution that SIP-5 provides, and beginning work on finding an even better solution through new, high-performance post-quantum cryptography.
Where this fitsSIP-5 is a proposal and it is written that way on purpose. It defines the minimum needed to keep accounts working across a quantum transition and leaves the bigger governance decisions for the moment they actually become relevant. Wallets, explorers, and other tooling would need time to add support, and the proposal calls for that groundwork to be in place before any cutoff is ever set.
A network built for modern trading has to plan for long term threats that are not immediate today. SIP-5 is what that looks like in practice.

Sei Labs zveřejnila Giga Whitepaper V2, který pro Sei Giga cílí na finalitu pod 250 ms a vyšší ochranu soukromí i proti MEV. Upgrade má zároveň zachovat více než 200 000 transakcí za sekundu.
The Sei Giga Whitepaper V2 is a major update to the original Giga Whitepaper published in May 2025. It introduces significant performance improvements and new features to Sei Giga, redesigning Sei Network from first principles into a blockchain with the ideal architecture for onchain trading.
Read the full whitepaper at: https://arxiv.org/pdf/2505.14914
What's New in V2The updated whitepaper addresses the questions the original left open. Where v1 described how Giga achieves speed and throughput, V2 adds how it will solve for privacy and fairness.
Faster FinalityThe new whitepaper introduces even faster performance for Giga's Autobahn consensus protocol. It now targets sub-250ms finality, down from the 400ms target in the original whitepaper. This will be delivered while maintaining 200,000+ transactions / 5 gigagas per second throughput across the network’s decentralized validator set.
Pre-Execution Privacy and MEV ResistanceThe new whitepaper introduces Sedna, a private transaction layer.
Transactions on Sei Giga will be encoded into fragments and distributed across multiple proposer lanes. This will ensure that no proposer will see the full contents of a transaction until ordering is finalized, giving the network pre-execution privacy. In short, a trade will never be visible until it is executed.
It also introduces a deterministic mechanism for ordering transactions across proposer lanes. This will make transaction ordering transparent, predictable, and secure against manipulation by any individual proposer.
Ultimately, Sedna will almost completely remove the MEV and censorship risk that affects every other smart contract blockchain.
The original Giga breakthrough: multi-proposer consensusIn traditional blockchains, one validator at a time is chosen to propose a block. That validator collects transactions, builds the block, broadcasts it, and then everyone votes on it across multiple rounds before it's finalized. Everything happens in sequence. You can't start the next block until the current one finishes the full propose-vote-vote-commit cycle. The speed of the entire chain is bottlenecked by one proposer at a time and multiple rounds of back-and-forth messaging.
Autobahn throws out that sequential model. Instead of one leader proposing blocks while everyone else waits, every validator will run its own "lane" and continuously stream batches of transactions in parallel. Each validator will propose independently and get a lightweight proof that its data is available from a small quorum of peers -- without requiring everyone to download everything upfront. A designated leader will then periodically take a snapshot called a "tip cut" that will capture the latest batch from every lane and commit them all at once through a streamlined two-phase vote.
This is what will enable Sei Giga’s immense throughput. Instead of being limited to however many transactions one validator can fit into one block per round, every validator will produce data simultaneously, and the consensus layer will synthesize their outputs together, sorting them deterministically by priority fee. The raw throughput ceiling will go from "one proposer's bandwidth" to the aggregate bandwidth of the entire validator set.
The Optimal Design for Institutional TradingBlockchains offer significant advantages over traditional trading venues. These include near instant settlement, shared liquidity, composability and 24/7 markets. However, in spite of these advantages, traditional traders are yet to adopt blockchain technology at scale.
For a trading environment to be successful, it has to be predictable. Trading on layer one blockchains today, because of the risks posed by MEV and possible censorship from block builders, is not predictable. This makes today’s blockchains fundamentally unsuitable for institutional traders.
When trading has taken off onchain, it has done so on venues which make the tradeoff of adopting centralized designs in order to make market structure more predictable. However in doing so, these exchanges expose themselves to the same centralization risks that affect legacy trading venues.
Sei's Giga upgrade will take the completely novel approach of introducing a multi-proposer architecture, and combining it with a private transaction dissemination layer. The result will be the first layer one blockchain that is actually suited for trading at scale. Sei Giga will offer pre-execution privacy, fair transaction ordering, MEV resistance, and censorship resistance while ensuring high throughput and near instant settlement.
Sei Giga will be the blockchain for trading.
What's NextSei Labs is well underway with the Giga Upgrade. Progress towards Giga can be followed on Sei Labs’ Giga Roadmap.
The whitepaper's future work section outlines several areas of active development:
Full transaction fee mechanism Autobahn consensus upgradesNew tokenomics for the SEI token The Giga upgrade will be the most complex blockchain upgrade since Ethereum's Merge. The network will transition to the full Giga protocol without regenesis and without taking any element of the network offline.

Disclaimer: The roadmap is subject to change based on development progress, market feedback, and other factors. Actual timelines, figures, and outcomes may vary.
SEI šel proti slabému trhu a vzrostl asi o 9 % na zhruba 0,058 USD, přičemž 24hodinový objem vyskočil asi o 190 % na 72 milionů USD. Rally podporuje short squeeze a očekávání upgradu Giga.
While most of the crypto market sold off on June 25, Sei Network's native token $SEI moved in the opposite direction, trading near $0.058 and up roughly 9% on the day as Bitcoin slipped under $60,000 and most major altcoins stayed firmly in the red.
The move was backed by real volume. CoinGecko data shows 24-hour trading volume for $SEI surged around 190% to approximately $72 million, confirming the price action was not a low-liquidity drift. @SeiNetwork was among the day's clear standouts in an otherwise weak market.
Short squeeze and Giga hype fuel the rally Two catalysts appear to be driving the outperformance. The first is a short squeeze that built around the $0.06 level, forcing leveraged bears to cover their positions and amplifying the upside move. The second is growing anticipation around the network's upcoming Giga upgrade.
Sei Labs published the Giga roadmap in late May 2026, targeting over 200,000 transactions per second and sub-400 millisecond finality. At the core of the performance leap is a protocol called Autobahn, a multi-proposer consensus mechanism. Traditional blockchains rely on a single block proposer at a time, creating a bottleneck. Autobahn lets multiple validators propose blocks simultaneously, which is how throughput scales from thousands to hundreds of thousands of TPS.
For context, Sei's prior throughput benchmarks sat in the range of 5,000 to 12,500 TPS. The Giga upgrade represents roughly a 40 to 50-fold increase in raw capacity. Beyond consensus, the upgrade also introduces asynchronous execution, allowing the network to process transactions in parallel and decouple execution from the consensus layer itself.
Phased rollout, not a single launch The upgrade is not a single event. Sei Labs is rolling it out progressively throughout 2026, with no single definitive launch date, and has set up a public milestone tracker at giga.seilabs.io.
Alongside the Giga upgrade, Sei Network committed in 2026 to becoming an EVM-only chain, deprecating its original CosmWasm smart contracts and native Cosmos transaction types through community-approved proposal SIP-3. Binance confirmed support for the full transition to EVM compatibility starting June 1.
The day's price action suggests the market is beginning to price in that technical roadmap, at least in the short term. Whether the rally holds will depend on whether the Giga milestones continue to arrive on schedule and whether broader crypto sentiment improves.
