For Ethereum Institutional’s founders, becoming an independent nonprofit rather than remaining within the foundation was a deliberate choice.

“The EF has always been quite vocal about its principle of subtraction,” Dawson said, referring to the organization diving up responsibilities for the network to other organizations . “This is an example of that increasing decentralization, and the number of nodes participating in representing Ethereum.”

Operating outside the foundation also gives the organization greater freedom, Walsh said.

“We feel like we have a lot more autonomy and freedom to work as an independent entity,” he said. “We can get a bit more opinionated, and a bit more aggressive, in terms of being able to support these teams.”

For years, the Ethereum Foundation has walked a careful line in how much influence it exerts over the ecosystem. Its mandate has largely been to coordinate protocol development and steward Ethereum’s technical roadmap, rather than act as a central authority driving business development or adoption. But as the network grew, some in the community pushed for the foundation to take on a more active role in areas like institutional outreach and ecosystem coordination, responsibilities it has increasingly chosen to decentralize instead.

Ethereum Institutional joins a growing network of organizations taking on specialized roles within Ethereum. Last month, EthLabs launched to support ecosystem development, while firms such as Etherealize, launched in 2025, have focused on bringing institutions onchain through commercial products and services.

Key Takeaways

• Evercore ISI maintained its Outperform stance with a $1,100 price objective following Costco’s June sales figures
• Comparable store sales climbed 7.6% domestically and 7.0% worldwide, with gas prices and currency fluctuations stripped out
• Goldman Sachs continued its Buy recommendation at $1,159; J.P. Morgan sustained its Buy designation at $1,100

• More challenging year-over-year metrics anticipated for July and August, with traffic comparisons becoming tougher by 100–150 basis points

Costco (COST) stock continues to receive support from Wall Street analysts following the warehouse club’s June sales disclosure, with several prominent firms reaffirming their positive outlooks and target prices.

Costco Wholesale Corporation, COST

Evercore ISI confirmed its Outperform designation while maintaining a $1,100 price objective. Analysts at the firm highlighted Costco’s core comparable store sales advancement of 7.6% domestically and 7.0% on a worldwide basis, with both metrics adjusted to exclude gasoline and currency translation impacts.

COST was hovering near the $1,050–$1,060 zone when these ratings were issued, suggesting Evercore’s target represents moderate appreciation potential from present levels. Data from InvestingPro indicates the shares may be trading above their Fair Value calculation.

Domestic customer traffic expanded 3.2% during June. This performance maintained the two-year combined traffic comparison above the 6% threshold for a seventh straight month, a pattern that Wall Street observers have been monitoring attentively.

Fuel station revenues contributed positively to the overall picture. These sales surged in the low-30% territory on a year-over-year basis, powered by a 22% increase in average retail prices and high-single-digit volume expansion in gallons dispensed.

Domestic transaction size growth, excluding gasoline, registered at 4.3%. Evercore’s analysis suggested approximately 1–2% stemmed from price inflation, with the remainder attributable to increased items per shopping trip and product category mix shifts.

Global Markets Show Moderation

Beyond U.S. borders, performance showed some moderation. Canadian core comparables reached 4.9%, representing a 120-basis-point decline from the preceding three-month average. Additional international territories recorded 5.6%, likewise down 110 basis points from recent performance levels.

June’s aggregate comparable sales expansion totaled 8.8%, although core comparables of 7.0% marked a pullback from May’s 8.7% figure.

Goldman Sachs analyst Kate McShane preserved a Buy recommendation with a $1,159 price objective. McShane observed that while June figures landed marginally below consensus forecasts, the shortfall was partially attributable to sales cannibalization from recently opened warehouses rather than any weakness in fundamental demand patterns.

McShane further emphasized that company leadership identifies no significant shifts in shopper behavior or the competitive landscape. Membership renewal patterns and customer traffic metrics remain healthy.

J.P. Morgan aligned with this perspective, likewise sustaining a Buy rating at a $1,100 price target.

Baird preserved its Outperform stance at $1,100. Gordon Haskett confirmed its Buy designation and elevated its target to $1,200, characterizing June’s 7.0% same-location sales expansion as marginally below expectations but nevertheless robust.

More Difficult Year-Over-Year Metrics Approaching

Not all analysts shared the same enthusiasm. DA Davidson and Citi both retained Neutral classifications, establishing targets at $1,000 and $1,020 respectively. Both institutions referenced the sequential slowdown in sales momentum from May through June.

Telsey confirmed its Outperform rating at $1,135 but conceded June’s performance fell short of its 10.6% forecast.

Evercore cautioned that year-over-year comparisons will intensify throughout the summer months. Traffic benchmarks become 100 basis points more demanding in July and 150 basis points more challenging domestically.

Costco’s aggregate revenue expansion over the trailing twelve-month period registers at 9.23%, underpinning a market capitalization of $422.69 billion.

Goldman’s McShane also referenced Costco’s pilot programs with standalone fuel facilities as a development worth monitoring, characterizing it as evidence of the company’s strategic focus on long-term member value enhancement.

The second dimension, Financial Performance, was assessed using data from Statista’s revenue database, which contains company financial data for the last five years. The companies had to meet certain criteria to be considered for the evaluation, including generating a revenue of at least $100 million in 2025. We evaluated financial performance on a variety of metrics, including short-term (2023-2025) and long-term (2021-2025) revenue growth, both in relative and absolute terms, changes in net income, asset growth, and the evolution of the company’s return on assets (ROA) (all 2023-2025).

The third dimension, Sustainability Transparency, was evaluated based on ESG data among standardized KPIs from Statista’s ESG Database and targeted data research. To formulate a comprehensive ESG index, multiple Key Performance Indicators were collected. For the environmental evaluation, this included the 2024 carbon emissions intensity and reduction rate compared to 2022, as well as the Carbon Disclosure Project (CDP) score. The social dimension assessed the share of women on the board of directors and the existence of a human rights policy. The governance dimension evaluated whether a company had a Corporate Social Responsibility (CSR) report adhering to the Global Reporting Initiative (GRI) guidelines and a compliance or anti-corruption guideline.

Nearly every transaction on Ethereum’s layer-2 networks passes through a single machine, run by a single company, called a sequencer. It orders trades, sets the pace of the chain, earns the fees, and can go dark or say no. This guide explains what sequencers actually do, why the most decentralized ecosystem in crypto runs its fast lanes through central operators, what can and cannot go wrong, and the roadmaps racing to fix it.

Here is an uncomfortable fact about the scaled, modern Ethereum: when you swap on an Arbitrum exchange, mint on Base, or pay on Optimism, your transaction is received, ordered, and confirmed by one machine, operated by one company. That machine is the sequencer, and it occupies a position of quiet, enormous power: it decides which transactions enter the chain and in what order, it collects the network’s fee revenue, and when it stops, as major sequencers have during outages, the entire network simply pauses, every app frozen at once.

The layer-2 rollups are how Ethereum scaled, moving execution off the congested base chain while inheriting its security, and they now carry a majority of the ecosystem’s activity. That success makes the sequencer the most consequential piece of centralized infrastructure in an ecosystem whose founding promise is decentralization, and the tension is not a secret; it is an engineering roadmap, with every major rollup publicly committed to fixing it and none finished. Meanwhile the base layer itself is being redesigned around adjacent ideas, with the coming Glamsterdam upgrade enshrining proposer-builder separation into the protocol, which will reshape the environment sequencers operate in.

This guide covers the sequencer honestly: what a rollup is and what job the sequencer does inside it, the specific powers a centralized sequencer holds and their real-world failure record, the crucial distinction between what a sequencer can and cannot do to your funds, the economics of sequencing and why operators are slow to give it up, the decentralization designs, shared sequencing, based sequencing, sequencer sets, competing to replace the single machine, and how to evaluate any L2’s actual trust profile today.

Rollups in one section, and the sequencer’s job

A rollup is a blockchain that executes transactions on its own fast, cheap environment, then posts compressed records of everything it did to Ethereum, inheriting the base chain’s security for its history. Optimistic rollups post results and allow a challenge window for fraud proofs; validity rollups post cryptographic proofs that the results are correct. In both designs, Ethereum is the court of final record, and the rollup is a high-throughput execution venue whose state can always, in principle, be reconstructed and verified from the data it posts down below.

Someone, though, has to run the fast venue in real time: receive the flood of incoming transactions, decide their order, execute them, hand users instant confirmations, and batch the results down to Ethereum. That someone is the sequencer. It is best understood as three roles fused: the mempool and matching engine that orders the flow, the block producer that executes it, and the shipping department that posts batches to the base chain. The ordering role is the powerful one, because in any financial system, transaction order is money: who gets the arbitrage, whose liquidation lands first, who buys before the price moves. On Ethereum’s base layer that power is fragmented across thousands of validators and an entire adversarial supply chain built to capture it; on almost every major rollup today, it belongs to one operator, appointed by the team, running the official sequencer.

Why did the most decentralization-obsessed ecosystem in software ship its scaling layer this way? Because centralized sequencing is fast, simple, and safe to bootstrap: one machine gives instant confirmations, no consensus overhead, clean upgrade paths, and a single throat to choke during the inevitable early bugs. The architects’ wager was that sequencing could be centralized temporarily because the rollup design strictly limits what the sequencer can do, a wager the next two sections examine from both sides.

What the sequencer can do to you, and what it cannot

The sequencer’s powers are real, and enumerating them precisely matters more than the usual hand-waving in either direction.

What it can do. It can censor: refuse to include your transaction, whether by policy, error, or legal compulsion, and regulated operators have compliance obligations that make selective exclusion more than hypothetical. It can order: place its own or favored transactions ahead of yours, extracting the value that ordering confers, invisibly and profitably; most major operators publicly forswear this, and the forswearing is a policy, not a protocol guarantee. It can stop: sequencer outages have repeatedly frozen major rollups for hours, halting every application simultaneously, a failure mode with no analogue on the base chain, where thousands of validators mean the chain simply does not stop. And it can set the pace and price of inclusion, since it is the sole gateway to the network’s blockspace in real time.

What it cannot do, and this is the rollup design’s genuine achievement: it cannot steal. The sequencer cannot forge a transaction spending your funds, because every transaction requires your signature and the fraud or validity proofs posted to Ethereum would expose any invented state. It cannot rewrite settled history, because the history lives on the base chain. And, critically, it cannot permanently trap you, because well-built rollups include an escape hatch: a mechanism to force-include transactions directly through Ethereum, bypassing the sequencer entirely, so that even a fully censoring or dead sequencer can only delay users, not imprison their funds. The delay is real, force inclusion is slow and clumsy, but the distinction between a chokepoint that can inconvenience you and a custodian that can rob you is the entire difference between the rollup model and a centralized exchange, and it is why the ecosystem tolerated centralized sequencing at all. The trust profile resembles a bridge with a strong trust-minimized design rather than a multisig one: concentrated operationally, constrained cryptographically.

The honest risk summary, then: your assets on a major rollup are secured by Ethereum; your access, timing, and fair ordering are secured by one company’s machine, policies, and legal situation. For a casual user the distinction rarely bites. For a trader whose profits live in ordering, for a protocol whose execution quality depends on fair ordering and whose liquidations must land on time, and for anyone in a jurisdiction a compliant operator might be told to exclude, the sequencer is the trust assumption that matters most and is audited least.

The outage record: what centralization has actually cost

The sequencer risk is not theoretical, and the incident record is the best syllabus for what single-operator infrastructure means in practice. Every major rollup has suffered sequencer downtime: hours-long halts from surging inscription traffic, stalls from software bugs in batch posting, freezes during upgrades that went sideways. The pattern across incidents is consistent and instructive. Funds were never lost, the base-chain security model held every time, and the networks resumed with their histories intact, which is the design working as promised. What stopped, each time, was everything else: trading froze mid-move, liquidation engines could not reach positions as prices moved, arbitrage broke against live markets elsewhere, and users learned that force-inclusion, the theoretical escape hatch, was in practice too slow and too technical to matter inside an incident measured in hours.

The subtler lessons sit in the second-order effects. During one prominent outage, the network’s applications discovered their own emergency procedures assumed a working sequencer: pausing markets, updating oracles, and even communicating with users all routed through the machine that was down. During another, the resumption itself became a trading event, as hours of queued transactions landed in a burst against stale prices, a miniature of the reconciliation dynamics every gap-prone market knows. And across all of them, the operator’s incident response, status pages, engineer availability, post-mortems, was the de facto governance of a multi-billion-dollar economy for the duration, performed by a company under no protocol obligation to perform it well.

The record’s summary is fair to both sides of the argument: the constrained-power design has truly protected funds through every failure, and the single-machine design has just as surely imposed correlated, economy-wide halts that a decentralized system would not, which is precisely the trade the roadmaps exist to unwind.

It is also worth placing the sequencer inside the rollup’s full trust stack, because it is the most visible dependency but not the only one. A rollup’s security rests on three legs: the data it posts to Ethereum, which is what makes reconstruction possible and which the blob-fee era made radically cheaper; the proof system, fraud or validity, that polices state correctness, several of which still run with training wheels, security councils and permissioned challengers standing in for mature proofs; and the sequencer, which governs liveness and ordering. Independent frameworks grade rollups across all three, and the grades routinely surprise users who assumed the marketing: networks celebrated as trust-minimized frequently carry upgrade keys and council powers that outrank the sequencer question entirely. The sequencer is the right place to start reading an L2’s trust profile. It is the wrong place to stop.

The economics: why giving it up is hard

Sequencing is not just power; it is revenue, and the revenue explains the pace of decentralization better than any technical obstacle. A sequencer collects the difference between what users pay for L2 transactions and what it costs to post their data to Ethereum, a margin that widened dramatically when Ethereum’s blob-based data pricing collapsed posting costs, plus whatever ordering value it chooses to capture or auction. For a major rollup this is a nine-figure annual business, and it currently flows to the operating company or foundation, funding development and, in several cases, constituting the primary revenue behind the network’s token.

Decentralizing the sequencer means distributing exactly this revenue, and the designs on the table are, among other things, proposals about who gets paid. That is not cynicism; it is the correct lens for evaluating the roadmaps, because a decentralization plan that never specifies where sequencing revenue goes is a plan that has not confronted its hardest question. It also frames the user’s side of the bargain today: centralized sequencing quietly subsidizes the networks users enjoy, the same revenue-and-token linkage question running through every fee-generating protocol, and every step toward neutrality redistributes a pie someone currently owns.

The numbers behind the revenue argument are worth one concrete paragraph. An L2’s gross margin is the spread between user fees collected and data costs paid to Ethereum, and the blob-fee era transformed that spread: posting costs for major rollups collapsed by orders of magnitude while user fees, though lower, fell less, leaving the large networks operating at gross margins that most software businesses would envy. Public dashboards track the arithmetic in real time, revenue in, data costs out, and the residual accrues today to whoever runs the sequencer. That residual funds engineering, subsidizes user fees during growth pushes, and, for token-bearing networks, constitutes the cash flow every valuation argument ultimately references.

Decentralization designs must answer where it goes: to a staked sequencer set as yield, to a shared network as service fees, to Ethereum validators under based sequencing, or to users as rebates, and each answer creates and destroys different constituencies. The engineering of neutral sequencing was largely solved on whiteboards years ago; the political economy of its revenue is the part still being negotiated, which is the single most clarifying fact about why the timelines are what they are.

The fixes: three roads to a neutral sequencer

Three families of designs compete to replace the single machine, each trading different things.

The first is the sequencer set: replace one operator with a permissioned or staked committee running consensus among themselves, rotating leadership, so that censorship requires collusion and outage requires correlated failure. It is the incremental path, and its critics note that a small committee of known entities is a smaller improvement than it appears, particularly against legal compulsion, which scales to committees easily.

The second is shared sequencing: independent networks whose business is providing decentralized ordering as a service to many rollups at once, with the added promise of atomic cross-rollup composability, transactions that execute across multiple L2s together or not at all, recreating some of the seamlessness the multi-rollup world fractured. The trade is a new external dependency and, again, the revenue question: a shared sequencer wants paying customers, and rollups guard their margins.

The third and most Ethereum-native is based sequencing: hand ordering back to Ethereum itself, letting the base chain’s validators sequence L2 transactions as part of block production. It maximally inherits Ethereum’s neutrality and censorship resistance, at the cost of Ethereum’s pace, confirmations at base-layer speed rather than the instant feel users have learned, though pre-confirmation designs aim to restore the speed. Based sequencing’s fortunes are entangled with the base layer’s own evolution: the Glamsterdam upgrade’s enshrined proposer-builder separation restructures exactly the block-production pipeline that based rollups would plug into, which is why sequencer roadmaps and Ethereum’s core roadmap now read as one document with two authors.

No major rollup has completed any of the three. The public commitments are real, staged plans, published designs, testnets, and the timelines have slipped for years, because the current arrangement works, earns, and only embarrasses its operators when something breaks. The realistic forecast is a long middle period of committees and hybrid designs, with full neutrality arriving network by network, unevenly, this decade.

A note on terminology prevents one common confusion: the sequencer is not the prover, and decentralizing one does nothing for the other. The prover, in validity rollups, generates the cryptographic proofs of correct execution; the sequencer orders and executes. A network can decentralize sequencing while proving remains one machine, or the reverse, and the two roles fail differently: a dead prover delays finality on Ethereum while the chain keeps running, a dead sequencer halts the chain while finality of past batches stands. Roadmap language blurs the roles constantly, and reading which one a decentralization milestone actually addresses is a small skill that pays for itself.

How to read an L2’s actual trust profile

For a user or builder choosing among rollups today, the sequencer question compresses into a practical checklist. Who runs the sequencer, and under what legal jurisdiction? Does the network have working force-inclusion, and what is its delay, the number that bounds worst-case censorship? What is the outage history, and did funds ever depend on the operator’s goodwill during one? Is there a published ordering policy, first-come-first-served, private mempool, auction, and any mechanism enforcing it beyond reputation? What stage is the decentralization roadmap actually at, running code versus blog post? And where does sequencing revenue go, because that answer predicts the roadmap’s pace better than the roadmap does.

The sequencer is the honest asterisk on Ethereum’s scaling triumph: the rollup ecosystem genuinely extended the base chain’s security to vastly more activity at vastly lower cost, and it did so by concentrating, temporarily and by design, the one power the base chain had most successfully dispersed. The asterisk is shrinking, slowly, under public pressure and published plans, and until it is gone, the single most useful thing a user can know about any L2 is exactly what its one important machine can and cannot do to them.

The wider stakes deserve a closing frame, because the sequencer question is Ethereum’s decentralization thesis meeting its scaling success, and the resolution will define what the ecosystem actually is. If the rollup era ends with a handful of corporate sequencers ordering most on-chain activity, then Ethereum will have rebuilt, at the execution layer, the intermediated structure it was designed to replace, with the base chain reduced to a settlement court for private venues. If the decentralization roadmaps deliver, based sequencing, credible committees, shared networks, then the scaling will have been genuine: more activity, same neutrality, the original promise kept at a hundred times the throughput. Both futures are still open, the incentives lean toward the first and the culture toward the second, and the outcome will be decided not by white papers but by the unglamorous engineering and revenue negotiations described above, network by network, over the next several years. Users are not spectators to that contest: the trust profiles are public, the alternatives are one bridge away, and where activity settles is the only vote the operators have ever reliably counted.

A practical postscript for builders, finally: sequencer risk is inherited. An application deployed on a rollup imports its sequencer’s outage record, censorship surface, and ordering policy as silent dependencies, and the mature practice, visible in how serious protocols now deploy, is to treat chain selection as a security decision, document the force-inclusion path in the runbook, and design liquidation and oracle machinery to fail safely through a halt. The sequencer is infrastructure, and the first rule of infrastructure applies: it is invisible until the day it is the only thing that matters.

The reader’s shortlist for following the story: the independent rollup-risk frameworks that grade each network’s sequencer, proofs, and upgrade keys; the networks’ own decentralization roadmap pages, read with dates, not adjectives; the outage post-mortems, which teach more per paragraph than any documentation; and the base-layer upgrade calendar, since Glamsterdam-era changes to Ethereum’s block pipeline reshape what based sequencing can offer. The chokepoint is well documented by everyone except the marketing, and the documentation is where the truth lives.

If one image should survive this guide, make it the geometry: Ethereum scaled by turning one broad, slow, neutral road into a system of fast toll lanes, each with a single operator at the booth. The lanes carry the traffic, the operators are competent, and the toll revenue is building better booths. But the map of who can stop which cars, and where, is now the most important map in the ecosystem, and every reader of this piece can pull it up for any network in about five minutes. Do that, once, for wherever your funds live. It is the highest-yield five minutes in crypto self-custody.

On July 9, 2026, Virax Biolabs (VRAX) revealed that its United Kingdom-based subsidiary has entered into an exclusive commercial distribution agreement spanning multiple countries with Fosun Diagnostics. The announcement triggered a dramatic 241% surge in VRAX shares during trading.

Virax Biolabs Group Limited, VRAX

The partnership establishes Fosun Diagnostics as the exclusive distributor of Virax’s ImmuneSelect portfolio — a collection of research-grade immune profiling tools — throughout six key Southeast Asian territories: Thailand, Vietnam, Indonesia, the Philippines, Singapore, and Malaysia.

Fosun Diagnostics operates as part of Fosun Medtech, itself a segment of Fosun Pharma. With Fosun Pharma recording RMB 41.662 billion in 2025 revenues (approximately $5.8 billion), Virax has secured a partnership with a financially robust distribution network throughout the region.

According to the agreement’s terms, Virax will deliver products such as ELISpot assay plates — specialized tools designed to evaluate cellular immune reactions — to Fosun through a purchase order system. The pricing model incorporates volume-based discount structures.

The collaboration launches immediately with product availability and initially concentrates on tuberculosis research initiatives in Thailand, with subsequent rollout planned for the remaining five markets.

The exclusive nature of the partnership depends on achieving specified minimum purchase volumes and performance benchmarks. Failure to reach these targets could result in modifications to the exclusivity provisions.

The agreement structure also provides flexibility for future expansion into supplementary product categories, increased supply volumes, and possible OEM or white-label manufacturing arrangements.

Understanding ImmuneSelect

ImmuneSelect represents Virax’s commercially available portfolio of research-only products. This line operates independently from ViraxImmune, the company’s diagnostic platform currently undergoing clinical trials and regulatory review processes.

This differentiation is significant. ImmuneSelect has already achieved market availability and is attracting commercial partnerships. ViraxImmune remains in the development pipeline.

James Foster, Chairman and CEO of Virax Biolabs, characterized the partnership as “a major step forward in the commercial rollout” of the ImmuneSelect platform throughout Southeast Asia.

Leon Zhang, International Commercial Head for China Domestic Business at Fosun MedTech, indicated that Fosun is exploring ELISpot-based research opportunities across the regional markets.

VRAX Company Overview

Virax Biolabs operates with a market capitalization of merely $2.53 million, positioning it firmly in micro-cap territory. The stock’s average daily trading volume hovers around 1.05 million shares.

The latest analyst coverage on VRAX assigns a Buy rating, accompanied by a $1.00 price target.

Current technical sentiment indicators classify the stock as Sell, creating a notable contrast with today’s substantial upward price movement.

The 241%+ gain places significant attention on the stock, though price volatility of this magnitude is relatively common for companies operating at this market capitalization level.

As of July 9, 2026, the distribution framework is operational and Fosun can immediately begin submitting purchase orders under the terms of the agreement.

This is the fork worth fighting over, and it is being missed because the debate is stuck on the wrong axis. Legislators frame the choice as safety versus freedom; critics frame it as protection versus privacy. Both accept a false premise, that keeping children out of adult spaces requires identifying the adults. It does not. The real choice is between two ways of verifying age: one that minimizes data and forgets you the instant you pass, and one that maximizes data and remembers everyone forever. Only the second is surveillance, and only the second is currently the path of least resistance.

The window to insist on the first is now, while these bills are still moving. The KIDS Act heads to a skeptical Senate. Chat Control 2.0 is targeting political agreement in July. In both cases the principle, that platforms should be able to tell adults from children, has effectively been settled. What has not been settled is whether that capability is built on privacy-preserving proofs or on a mountain of uploaded passports. That is a technical decision with civil liberties consequences, and it is being made, right now, largely by default.

There is a larger reason to settle this well, and settle it now. The old sorting of internet traffic into “bot or human” is already breaking down: a verified third category is arriving, AI agents acting, with authorization, on behalf of people, companies and governments, and they will soon need to prove what they are permitted to do without unmasking whoever stands behind them. “Know Your Agent” will demand the very same privacy-preserving architecture we are arguing over now for people. Decide it well for human age checks, and we set the pattern for everything that follows. Decide it badly, and we hard-wire surveillance into the identity layer of the internet, for humans and machines alike.
