LastPass customer info leaked again after third-party data breach
LastPass, the password manager that inadvertently facilitated the theft of $150 million in crypto from Ripple co-founder Chris Larsen, is now warning users that their personal information was stolen via an attack on third-party market firm Klue.
The company emailed its customers this week to inform them that Klue was breached on June 11 and that data including customer names, phone numbers, email addresses, and physical addresses, as well as support case data and sales-related data, had been stolen.
Despite this, LastPass stressed that the incident affects only Klue-integrated systems and that “LastPass products, services, and infrastructure were not impacted in any way and customer vaults remain secure.”
Multiple cybersecurity firms reliant on Klue have also seen customer data leaked.
The cybercrime group Icarus claimed responsibility for the breach and is reaching out to users and threatening to leak their data.
LastPass users have been warned to stay vigilant about social engineering and phishing attacks that may attempt to swindle them out of more information and funds.
LastPass’s 2022 breach lost Ripple co-founder $150M
LastPass suffered multiple major breaches in 2022 that saw sensitive data stolen from customers’ password vaults.
Crypto sleuth ZachXBT noted in 2024 that a threat actor was able to use data from this breach to steal $5.4 million worth of crypto from over 40 addresses.
Prior to this, in 2023, ZachXBT also reported that roughly $4.4 million was drained from over 25 victims because of the 2022 breach.
Possibly the biggest theft from LastPass involved Ripple co-founder Chris Larsen, who lost $150 million worth of crypto after his private keys were leaked in the 2022 breach.

Two people behind a $389 million cryptocurrency laundering service dubbed “AudiA6” have also, according to ZachXBT, helped launder stolen funds from LastPass users.
LastPass was fined £1.2 million by the UK’s Information Commissioner’s Office last year over the 2022 data breach.
The body claimed it impacted 1.6 million UK users, and that LastPass “failed to implement sufficiently robust technical and security measures, which ultimately enabled a hacker to gain unauthorised access to its backup database.”

Sam Altman ChatGPT AI Predicts Shocking Bitcoin Price By The End of 2026
ChatGPT AI just put a fresh shocking predicts on Bitcoin price prediction that paints a very different picture from where price sits right now. The model sees a climb toward $140,000 to $180,000 by the end of 2026, nearly triple current levels.
The bull case leans on timing as much as fundamentals. Bitcoin is trading near $62,640 today, and if the market follows a typical post halving rhythm, the next major leg higher could kick off around November as liquidity improves and risk appetite returns.
A handful of catalysts are stacked up behind that thesis. The CLARITY Act could finally deliver long awaited regulatory certainty for digital assets. Continued support from the Trump administration adds another layer, given its stated goal of making the United States a global leader in crypto.

The Strategic Bitcoin Reserve initiative is another piece worth watching, alongside accelerating institutional adoption through ETFs and deeper stablecoin integration across traditional finance.
If those forces line up the way the model expects, bitcoin could reclaim $100,000 first before pushing into that $140,000 to $180,000 zone.
The bear case keeps the door open for a much slower outcome. Macroeconomic weakness, delayed regulation, or weaker ETF inflows could keep demand muted for longer than bulls want.
Under that scenario, bitcoin stays trapped somewhere between $50,000 and $80,000 for an extended stretch instead of breaking out. Even so, the model still leans toward higher prices overall, with November standing out as the most likely window for a broader resurgence.
Bitcoin Price Prediction: BTC Grinds Toward Its November Reckoning
The daily chart shows bitcoin at $62,769 after sliding from a high near $124,000 set last fall. That entire move down has been one long, grinding downtrend with a brief relief rally into May that topped out near $82,000 before rolling over again.
Price recently bottomed near $60,000 in early June and has spent the last few weeks stabilizing in the low $60,000s. That kind of basing action after a sharp drop often signals sellers losing steam rather than a trend reversal just yet.
Immediate resistance sits near $68,000, then a tougher wall around $76,000 where the May rally stalled out. Support holds at $60,000, with that recent low acting as the line bulls need to defend.
RSI is reading 37.84 against a signal line of 38.27, so momentum is sitting just under its own average, essentially flat after months of weakness. That tiny gap shows neither buyers nor sellers have firm control right now.
Overall momentum looks like it is leveling off rather than trending hard in either direction. If bitcoin can clear $76,000 and turn it into support, the runway toward six figures and that bigger 2026 target starts to look a lot more believable.

LiquidChain Is Catching the Attention of Bitcoin holders: ChatGPT AI Predicts It’s the Next 100x
Most rotations are only obvious after they’re done. This one is still happening.
Bitcoin, Ethereum, and XRP have stalled against the same resistance for weeks, waiting on macro catalysts that keep sliding to next quarter. Holding and hoping isn’t a strategy. It’s a queue.
Smart capital doesn’t wait in that queue. It moves before the trade is obvious to everyone else.
Here’s why early-stage infrastructure plays differently: a small market cap means a modest rotation can move price by multiples. The gap between what a project is worth and what the market currently prices it at is where the return lives, and that gap only exists before the crowd finds it.
DeFi loses real money to fragmentation every day. Bitcoin, Ethereum, and Solana run on separate liquidity systems with no native bridge between them, so every cross-chain move costs fees, slippage, and failed transactions.
LiquidChain merges all three into a single execution layer. One deployment, full access, no cross-chain tax.
The market hasn’t found it yet.
Presale: $0.01454, with $860,000 raised.
Worth saying plainly: execution is unproven and adoption is unknown. This isn’t a safe bet, it’s an early one. Established coins offer a calmer ride to a ceiling you can already see. This is a bet on a ceiling that doesn’t exist yet.

Dogecoin Case: Is DOGE Still the King of Memes?
Dogecoin is trading near $0.078 in a depressing week that saw it lost 9% of its value. Eleven years after launching as a Shiba Inu joke, DOGE still carries a $12 billion market cap and a place in the top 11. But is it still the king of memecoins?
No major DOGE-specific catalyst, like a protocol upgrade or institutional announcement, has emerged in the past few years for DOGE, yet it still has a huge following. If you are in crypto or ever trade crypto, there’s 99% chance you heard DOGE.
Beyond DOGE, meme coins remain approximately 1% of the total crypto market value. It’s a niche that rotates fast when sentiment shifts. With the launch of SpaceX and Elon Musk’s backing, can Dogecoin run once again? Or has it become an old dog now?

Can Dogecoin Price Hold $0.078 Support or Is a Deeper Flush Coming?
DOGE is consolidating between $0.078 support and $0.082–$0.084 resistance. Neither level has broken cleanly, which is exactly what indecision looks like on a chart.
The setup carries a downside bias. A weekly loss in the 8–9% range without a bounce catalyst means sellers are absorbing any intraday recovery attempts rather than stepping back. Volume is not confirming accumulation. Elon Musk’s connection to DOGE narrative has historically acted as an ignition switch, absent a fresh Musk-driven social catalyst, that fuel isn’t in play.

Dogecoin’s 15,000%+ return since 2013 is a real number. The uncomfortable counterpoint is that most of those gains were compacted into two parabolic windows, both tied to social momentum rather than protocol development. Until DOGE demonstrates utility beyond community speculation, the price remains a sentiment thermometer. Right now, Dogecoin is useful for reading the room, harder to trade on fundamentals.

Maxi Doge Targets Early-Stage Upside as DOGE Consolidates at Key Levels
Traders watching DOGE grind sideways with an 8% weekly loss already know the calculus: late-cycle meme exposure at a $12 billion market cap means you need enormous capital inflows just to move the needle. The asymmetry simply isn’t there at this size. That’s where early-stage presales draw attention, not as a replacement thesis, but as a different risk profile entirely.
Maxi Doge ($MAXI) is positioning directly inside the meme coin category but built around a trading-community identity. The “240-lb canine juggernaut” framing is deliberately absurd, but the mechanics underneath it are concrete.
The presale has raised $4.8 million at a current price of $0.0002825 per token on Ethereum (ERC-20). Features include holder-only trading competitions with leaderboard rewards, a Maxi Fund treasury allocated to liquidity and partnerships, and dynamic staking APY for holders.
The “never skip leg day, never skip a pump” ethos is corny, yes, but viral-ready, as it targets exactly the retail energy that drove DOGE’s early cycles.
Research Maxi Doge and size accordingly. But if the meme cycle rotates and DOGE’s ceiling is capped by its own mass, early-stage exposure with genuine community mechanics is worth understanding.

Peter Schiff warns Strategy could sell Bitcoin as MSTR stock sinks
Strategy’s common stock has fallen below $100, prompting renewed criticism from Bitcoin skeptic Peter Schiff, who argues that further declines could leave the company facing difficult decisions over its Bitcoin treasury strategy.
Summary
- Peter Schiff warned that a deeper MSTR stock decline could eventually force Strategy to sell Bitcoin.
- Strategy raised $335.5 million through stock sales, allocating $35 million to buy 520 BTC.
- CryptoQuant urged Strategy to pause Bitcoin purchases and rebuild cash reserves as dividend obligations rise.
According to comments posted by Schiff on X, sustained pressure from short sellers could push Strategy into a situation where repurchasing its own shares becomes more attractive than continuing to accumulate Bitcoin.
He suggested that selling some Bitcoin to fund stock buybacks could help narrow the discount between the company’s market value and its underlying assets, though he questioned whether such a move would restore investor confidence.
Schiff also claimed that any forced sale of Bitcoin by Strategy could have consequences for the broader market, arguing that liquidating part of its holdings would likely weigh on Bitcoin prices.
The warning comes as Strategy shares continue to slide. MSTR traded at $96.27 on June 24, down 7.2% during the session and near its lowest level in two years. Regulatory filings show the stock has lost nearly 20% over the past five trading days and more than 38% over the last six months.

Cash reserves face growing scrutiny
Recent capital allocation decisions have added to the debate surrounding Strategy’s balance sheet. Company disclosures show that Strategy sold approximately 2.71 million MSTR shares last week, generating about $335.5 million in proceeds.
Executive Chairman Michael Saylor later disclosed that the company used roughly $35 million of that capital to purchase 520 Bitcoin. At the same time, Strategy increased its U.S. dollar reserves by about $300 million, bringing its cash balance to approximately $1.4 billion.
Saylor stated that the larger cash position is intended to support the credit quality of Strategy’s Digital Credit securities, a group of products that has become increasingly important to the company’s financing structure.
Separate concerns have emerged from on-chain analytics firm CryptoQuant, which recently urged Strategy to slow its Bitcoin purchases and focus on rebuilding liquidity. According to CryptoQuant, annualized dividend obligations tied to the company’s preferred stock products have climbed to roughly $1.2 billion.
Preferred stock obligations draw attention
CryptoQuant’s concerns center on STRC, Strategy’s perpetual preferred stock product. The firm reported that the company’s cash reserves have fallen 38% in 2026, while dividend coverage has dropped from more than seven years to about 14 months.
According to CryptoQuant, restoring coverage to 24 months would require roughly $2.8 billion in cash, nearly double Strategy’s current reserves.
CryptoQuant CEO Ki Young Ju also argued that Strategy’s Bitcoin purchases are no longer a major price catalyst. He said buying during periods of strong selling pressure may help defend Bitcoin’s range but is unlikely to spark a new rally.
Given those conditions, Ju recommended pausing additional Bitcoin purchases, rebuilding cash reserves, and adopting a more structured buying strategy.
In a follow-up X post on June 24, Schiff expanded his criticism to Strategy’s STRC preferred stock. He argued that the security had been marketed to risk-averse retirees as a lower-volatility way to gain exposure to the company’s Bitcoin strategy, despite falling more than 5% on the day and over 17% below levels where many investors reportedly purchased shares the previous month.
Schiff further claimed that the decline had erased nearly two years of dividend income and accused Saylor of making “material misrepresentations” when describing the preferred stock.

Trump refuses to sign law with U.S. CBDC ban, demands approval of elections bill
If congressional Republicans pivot toward further work on the elections-focused legislation, that may squeeze their bandwidth for other legislation. GOP lawmakers were already pushing again for Senate action on Trump’s favored bill on Wednesday.
“There is no path for the SAVE Act becoming law,” said Jaret Seiberg, a policy analyst at TD Cowen, in a Wednesday research note. “Senate GOP would need to eliminate the filibuster, a step they already have rejected. Even absent the filibuster, it is not clear the bill has the support of 50 senators, given worries about have to prove citizenship.”
Before his cancellation of the housing bill signing, Trump had posted on his social-media platform that the housing bill is of “minor importance compared to lower interest rates” and other congressional priorities, and he criticized the involvement of Democratic Senator Elizabeth Warren.
The president has a constitutionally designated 10-day window to weigh approved bills for signature once they land on his desk. If he were to veto it, the bill did pass with enough of a margin to reject that veto, though Republican allies of the president would have to agree to override his sentiment.
UPDATE (June 24, 2026, 16:01 UTC): Adds comment from TD Cowen.

Prevailing Currency in Digital Assets: Infrastructure
This trend is becoming even more relevant as real-world assets enter the digital landscape. Stablecoins have already demonstrated the power of blockchain-based representations of traditional value, becoming the most successful digital asset use case to date. Tokenized deposits, bonds, funds, and other real-world assets are poised to follow, expanding the range of opportunities available to businesses and individuals worldwide.
For the end user, however, the underlying asset may become increasingly irrelevant. Most people are unlikely to care about the blockchain protocol, token standard, or settlement mechanism powering a transaction. What matters is accessibility, speed, security, and trust. Users want to access global opportunities using their local resources, through partners they know and platforms they can rely on.
In this environment, the long-term competitive advantage belongs to those who build and operate the infrastructure connecting participants, assets, and markets. Coins may evolve, protocols may change, and new forms of digital value will continue to emerge. But the institutions that enable trust, connectivity, and seamless access will remain at the center of the ecosystem.
The prevailing currency in digital assets may change over time. Infrastructure, however, is what endures.

SBI Group Launches JPYSC, Japan’s First Trust Bank-Backed Yen Stablecoin
JPYSC has officially launched today, Japan’s first trust bank-backed yen stablecoin, issued by SBI Shinsei Trust Bank and distributed exclusively through SBI VC Trade. The token is pegged 1:1 to the yen, classified as an electronic payment instrument under Japan’s Payment Services Act, and carries no transaction cap, a structural detail that separates it from every prior yen stablecoin attempt in the domestic market.
Earlier fund-transfer-type stablecoins in Japan were subject to a 1 million yen ceiling on both transactions and balances, a constraint that rendered them useful for retail payments and little else. JPYSC removes this ceiling, opening the door to institutional-scale on-chain settlement, tokenized RWA transactions, and cross-border FX use cases that the prior generation of Japanese stablecoins structurally could not support.
Discover: The Best Crypto to Diversify Your Portfolio
Trust-Bank Structure: Digital Yen Stablecoin Regulatory Differentiator
The structural distinction that makes JPYSC huge within Japanese crypto regulation is the issuance architecture. SBI Shinsei Trust Bank holds reserve assets, cash, and highly liquid yen-denominated instruments in a segregated trust account. Holders carry a direct legal claim under trust law to the underlying yen.
The Payment Services Act classification as an electronic payment instrument reflects this structure. Japan’s revised framework created a legal pathway specifically for trust bank stablecoins, and JPYSC is the first product to reach the market through that route.
Singapore-based Startale Group, co-developer of JPYSC alongside SBI, provided the blockchain infrastructure and developer tooling; Startale CEO Sota Watanabe described the token as infrastructure for “Japanese retail users, enterprises, and global financial institutions” to transact onchain.
In October 2025, JPYC received approval as Japan’s first legally recognized yen stablecoin, but under the fund-transfer framework with its 1 million yen cap intact. Japan’s three megabanks, MUFG, SMBC, and Mizuho, are jointly developing a stablecoin and announced plans in June 2026 to begin live commercial transactions during fiscal year 2026. JPYSC beat them to market with a structure the megabank project has not yet matched publicly.
The multi-chain architecture Startale has outlined for JPYSC, targeting deployment across multiple public chains via Sony-backed infrastructure, would further differentiate the token if it materializes. A single-chain yen stablecoin is a payment rail. A multi-chain yen stablecoin with no transaction cap and trust-law reserve backing starts to look like foundational settlement infrastructure for Japan’s on-chain financial market.

JPYSC Is Infrastructure, Not a Liquidity Event
Initial access to JPYSC is restricted to SBI VC Trade account holders, a deliberate constraint SBI has indicated will remain in place until regulatory and tax treatment is fully clarified. This is a reasonable sequencing decision for a novel instrument, but it also means the token’s near-term addressable market is limited to SBI’s existing exchange client base.
Don’t Miss Out on Our $1,000 USDT Airdrop on ByBit
SBI VC Trade has flagged a JPYSC lending service as a near-term addition, which would add yield mechanics to a pure settlement instrument and potentially accelerate institutional adoption. The tokenized RWA angle is the more consequential long-term use case. It’s no secret that a yen-denominated stablecoin with no cap and trust-law backing is a natural settlement layer for Japan’s growing pipeline of tokenized securities, real estate, and structured products.
The regulatory trajectory across major jurisdictions reinforces why this structure matters. Ripple’s RLUSD received MiCA approval in the EU on the strength of its regulated, reserve-backed structure. Regulatory legitimacy is increasingly the price of admission for stablecoins targeting institutional flows, and JPYSC clears that bar within the Japanese framework.

SpaceX (SPCX) Stock Plunges 10.6% Despite Securing $6.3B AI Computing Contract
Key Takeaways
- Reflection AI, an emerging AI firm, has entered into an agreement with SpaceX for Nvidia GB300 chip access at the Colossus 2 facility, costing $150 million monthly.
- The contract extends through 2029, potentially generating approximately $6.3 billion in total revenue over its duration.
- Despite lacking any released products or revenue streams, Reflection AI secured $2 billion in funding last October, achieving an $8 billion valuation with Nvidia’s backing.
- Following the announcement, SpaceX stock (SPCX) experienced a decline of approximately 10.6%, even though the contract represents substantial recurring income.
- The Colossus data center portfolio now includes major clients such as Anthropic, Google, Cursor, and Reflection AI.
SpaceX (SPCX) stock experienced a significant decline of roughly 10.6% following news of a massive $6.3 billion computing agreement with Reflection AI — an AI startup that has yet to launch a commercial product or generate any revenue.
Space Exploration Technologies Corp, SPCX
CNBC broke the story on June 22. According to the agreement’s structure, Reflection AI will gain prompt access to Nvidia GB300 processors located within SpaceX’s Colossus 2 Memphis data center. Monthly installments of $150 million commence on July 1, 2026, with the contract extending until 2029.
If executed in full, the arrangement would generate roughly $6.3 billion in total payments. Both parties retain the option to terminate with 90 days’ notice following an initial three-month period.
Neither SpaceX nor Reflection AI provided responses to Reuters’ inquiries.
Reflection shared on LinkedIn that “additional compute capacity enables us to further advance the boundaries of open models,” offering no additional specifics.
Expanding Client Portfolio
SpaceX has been methodically assembling an impressive collection of high-profile computing clients at its Colossus facilities. Anthropic secured exclusive access to all of Colossus 1 for approximately $1.25 billion monthly. Google subsequently committed to $920 million per month for transitional capacity while constructing its proprietary data centers, with service beginning October this year and continuing through June 2029. Reflection represents the fourth major tenant in a portfolio that emerged from nothing within the past year.
Reflection was established in early 2024 by co-founders Misha Laskin and Ioannis Antonoglou, both alumni of Google DeepMind. Laskin previously directed reward modeling efforts for Gemini. Antonoglou co-developed AlphaGo. The startup completed a $2 billion funding round last October at an $8 billion valuation, with Nvidia serving as the lead investor. By spring 2026, industry reports suggested its valuation had climbed toward $20 billion. The company has not yet released any public model.
The organization has established itself as an open frontier laboratory concentrating on government and national security applications, including initiatives connected to the Department of Energy’s Genesis Mission and various Pentagon AI contracts.
Understanding the Stock Movement
Despite securing billions in guaranteed recurring revenue from an additional tenant, SPCX shares fell approximately 10.6% on announcement day — marking the sharpest single-day decline since the company’s June 11 public debut at a $1.77 trillion valuation.
The market reaction surprised several analysts. SpaceX is securing guaranteed, recurring payments against existing infrastructure assets. The Colossus 2 agreement alone contributes $1.8 billion in annual contracted revenue. This financial dynamic doesn’t immediately explain the negative market response.
Looking Ahead
The agreement features a 90-day termination provision following the initial three-month period, meaning the critical evaluation point arrives around late October. Should Reflection choose not to exercise this exit option, the lease essentially transitions from potentially temporary to confirmed long-term demand.
Reflection’s LinkedIn communication mentioned advancing the frontier on “open models.” The company has not disclosed a timeline for any public product release.
SpaceX, Reflection AI, and Nvidia had not provided additional comments by publication time.

Why Perfectly Fair Crypto Transaction Ordering Isn’t Achievable
Today’s blockchains already treat consensus as a matter of two properties: nodes must agree on the same history (consistency) and the system must keep processing transactions (liveness). But that framing leaves a crucial gap—what users ultimately care about is not only whether transactions get confirmed, but whether their relative ordering is meaningfully fair when multiple parties submit transactions that can interact economically.
A new line of research is trying to formalize “transaction order fairness” and map out what is possible under real-world networking constraints. The core takeaway: perfect “first-come, first-served” ordering is mathematically out of reach in asynchronous distributed systems, even before considering adversaries. The practical question becomes how to approximate fairness while keeping liveness and minimizing opportunities for extractive behavior.
Key takeaways
- Perfect receive-order fairness (“first-seen, first-executed”) cannot be guaranteed on public networks because messages arrive at different times and there is no shared clock.
- Even when each node has a clear local arrival order, group preferences can conflict—captured by the Condorcet paradox—making a single linear order impossible to satisfy.
- Hashgraph’s fairness model uses a DAG of events with median timestamps to respect causal relationships while bounding how far adversarial influence can shift ordering.
- BOF-style protocols (from the Aequitas/Themis line of work) relax fairness by ordering transaction “batches” derived from Condorcet cycles, enabling stronger liveness guarantees.
Why “fair ordering” is harder than it sounds
In public blockchains, ordering isn’t just an implementation detail—it can decide who captures value and who pays. When privileged roles like block builders or sequencers determine execution order, they can potentially exploit that power through strategies that front-run, back-run, or sandwich transactions. Research on maximal extractable value (MEV) describes this as a direct consequence of who can influence ordering.
To counteract this, some proposals treat transaction ordering fairness as a third consensus objective alongside consistency and liveness. The general idea is to constrain the block producer’s ability to bias ordering beyond what the network conditions and protocol rules imply—making execution more predictable and less vulnerable to systematic exploitation.
But the most intuitive fairness notion runs into a structural limitation. In an asynchronous distributed system, there is no globally defined reception order because different nodes observe transaction messages at different times. Without a shared clock and with arbitrary message delays, no protocol can ensure that every node’s “arrival order” maps perfectly onto a single network-wide execution order.
The Condorcet paradox: why majority “first” can loop
The strongest form of fairness is often described as Receive-Order-Fairness (ROF): if most nodes receive transaction A before transaction B, then A should be processed before B. ROF sounds straightforward, but the network reality undermines it. Nodes see messages at different speeds, so different nodes can legitimately observe different pairwise “firsts.” Even if those local observations are consistent for each node, the collective can still become inconsistent.
This is where the Condorcet paradox comes in from voting theory, and it translates cleanly to distributed ordering. Even when each participant has an internal preference for which of two items comes first, the majority preference across multiple pairs can form a cycle:
- Most nodes see A before B
- Most nodes see B before C
- Most nodes see C before A
When that happens, there is no single linear ordering that satisfies all majority pairwise preferences. The implication for blockchain consensus is direct: if fairness is defined too strictly in terms of majority “first-seen” comparisons, the protocol may be unable to produce any ordering that matches the majority view across all pairs.
Because of this impossibility, systems aiming for “fairness” must adopt weaker—but more achievable—guarantees.
Hashgraph’s approach: DAG causality plus median timestamps
Hedera’s hashgraph algorithm tackles transaction ordering fairness through a leaderless, event-driven model. According to the described model, transactions are transformed into cryptographically linked events inside a directed acyclic graph (DAG). Consensus ordering then emerges from how nodes collectively observe and sign those events, rather than from a single proposer unilaterally choosing a sequence.
Operationally, when a node receives a transaction, it creates an event and gossips it to peers. Subsequent events record hashes of earlier events they have seen, and nodes digitally sign the result. This creates a provable causal structure: if one event is an ancestor (direct or indirect) of another, the protocol provides a cryptographic guarantee about which event was created first by some node.
The ordering logic then distinguishes between events with causal relationships and those that are concurrent. Events connected by DAG ancestry are ordered according to their causal dependencies. For concurrent events (those without ancestor relationships), the protocol resolves relative ordering using a “round-received” concept and then refines that using median timestamps.
Median timestamps, as described, are derived from a set of node-reported local receive times, but constrained by the hashgraph’s ancestry. That constraint matters: nodes cannot claim to have observed an event before its causal predecessors without creating detectable inconsistency in the DAG. Under the standard assumption used in Byzantine fault tolerance—fewer than one-third of nodes are Byzantine—the median timestamp should remain within a bounded range of honest timing reports, limiting adversarial ability to arbitrarily skew ordering.
However, hashgraph’s fairness is not infinite. The described research emphasizes that fairness is bounded by an adversarial “surface” where a node can still influence its gossip behavior: which events it relays first and whether it delays relaying. While the DAG cannot fabricate a false causal history, strategic propagation patterns can reshape the inputs that ultimately feed into median timestamp computation.
There is also the Condorcet paradox risk for concurrent events. The DAG eliminates ambiguity for causally linked events because the ancestry is fixed at creation. But concurrent events can still be observed in different orders by different nodes, leaving some ordering tension that is then handled by the protocol’s round and median mechanisms.
BOF protocols: fairness by collapsing Condorcet cycles
Another line of work frames fairness differently—by explicitly embracing cycles. BOF (Batch-based Order Fairness) protocols define “blocks” as sets of transactions that form a Condorcet cycle, then enforce fairness at the level of how those blocks relate, while allowing arbitrary internal ordering inside each block.
In the BOF formulation described, fairness is controlled by a parameter γ: if a sufficient fraction γ of nodes observe block b before block b′, then honest nodes cannot output b after b′. When fairness constraints induce a cyclic relation, the protocol collapses the strongly connected component (SCC) into a single batch/block, because no linear order can satisfy all the directed constraints simultaneously.
A key practical point is that this approach relaxes strict ROF requirements. When a cycle occurs, internal ordering becomes irrelevant to the fairness guarantee, since the protocol treats the entire cycle participation as atomic at the batch level. The research description notes that deterministic rules (such as a hash-based rule) may then sort transactions within the batch, but the fairness criterion does not attempt to make those internal orders correspond to any global first-seen preference.
The Aequitas protocol line is described as having weaker liveness: its strict fairness constraints require waiting for complete Condorcet cycles, and if cycles can chain indefinitely, finalization delays could grow without bound—creating a “freeze” risk.
Themis is introduced as a refinement intended to preserve γ-BOF while improving liveness. As described, Themis also builds a dependency graph and collapses SCCs during a “FairFinalize” stage, but it avoids waiting for the full cycle to close. Instead, it uses deferred ordering and “batch unspooling” so SCCs can be output incrementally while new transactions keep flowing. The result, as presented, upgrades Aequitas’ weak liveness into standard liveness with a delay bound.
Themis also addresses communication scaling concerns. In its basic form, participants exchange messages with most other nodes, leading to communication growth roughly proportional to the square of the network size. An optimized variant, SNARK-Themis, replaces much of that direct exchange with succinct cryptographic proofs, so verification can scale more efficiently as the node count increases.
Finally, the protocol design includes a mechanism to prevent denial-style manipulation. If a malicious proposer tries to exploit the system by proposing an empty block, Themis’s deferred ordering accepts a partially ordered batch and leaves exact finalization to a subsequent honest proposer, based on verifiable transaction relationships rather than discretionary choices by the current proposer. This is framed as a way to tie finalization to bounded network delay rather than arbitrary proposer behavior.
What to watch next
The central unresolved question across these approaches is how to balance fairness guarantees against the operational costs—especially complexity, communication overhead, and the practical handling of concurrency. As more consensus designs incorporate formal ordering fairness ideas, investors and builders should watch for implementations that demonstrate bounded delays in real network conditions while maintaining robustness against adversarial reordering.
