05 September Why is Bitcoin Knot so popular?

Bitcoin Knots, a full-node client maintained by Luke Dash JR, has become the focus of controversy within the Bitcoin community due to its integrated spam filter and more stringent policy control compared to Bitcoin Core. Knot users argue that filtering transactions such as ordinals, runes, stamps, coin joins protects the role of Bitcoin as a financial network, but as miners often include them via direct submission channels like marathon slipstreams, filters have not proven that they actually do much to prevent such activities. The conflict sparked a fierce debate among social platforms, drawing comparisons with the block-sized war of 2017, and spurring a surge in the adoption of over 4,200 knots by September 2025 from just 69 nodes in January 2024. Although it splits, this shift could increase client diversity, reduce reliance on Bitcoin core, and enhance Bitcoin’s resilience despite unresolved ideological clashes against neutrality and restrictions.

What is Bitcoin Knot? Why is it important?

Bitcoin Knots is an alternative full-node client for Bitcoin Core and renowned Bitcoin developer Luke Dash Jr. integrates additional features with more stringent policy controls. Unlike Core, Knots offers users the ability to filter transactions that take into account “spam”. For example, embedding arbitrary data into the blockchain via Op_return. These filters allow node operators to reject data-heavy or non-financial transactions at the Mempool level, giving them greater control over which activities the node handles. This approach has made the knot appealing to users who want to prioritize financial use cases for Bitcoin and limit what they consider to be a wasteful or exploitative use of block space.

The current discussion focuses on the decision to remove the long-standing 80-byte Op_return Cap of Bitcoin Core V30, allowing a large amount of arbitrary data to be embedded in a transaction. Core developers argue that this change is consistent with Bitcoin’s neutrality principle. If a transaction is valid and you pay a fee, it must be relayed and mined without judgment about its purpose. They suggest that lifting restrictions drive wider innovation, such as on-chain document validation and NFT-style use cases. In contrast, knot supporters see the removal of restrictions as opening networks and opening spam, inflated blockchains and distracting from Bitcoin’s main role as a financial settlement system.

This conflict is more than technical disagreement, reflecting a deeper ideological division of Bitcoin’s identity. For core advocates, neutrality means dealing with any use case where you pay a fee to maintain the integrity of the system that is permitted, but knot advocates argue that neutrality requires Bitcoin to be stored as a lean, reliable financial system rather than a general-purpose data ledger. This controversy has led many node operators to move from core to knot. The network knot has risen sharply in 2025. For some, this shift is not just about performance and policy preferences, but also about resisting what they perceive as a core unilateral authority in the direction of Bitcoin.

As the October 2025 core V30 release approached, this debate has addressed the historic echo of the 2017 block-sized war. Currently, the increasing percentage of the network is a knot and an exit symbol that signals the attachment of a resistor to changes in the core policy. The risk of hard and soft forks has not yet arisen, but the risk of network fragmentation looms if the new rules in the core lead to incompatibility with the knot approach, but is much more likely to “vote on the feet.” Whether this divergence will strengthen Bitcoin through client diversity or threaten its unity remains uncertain, but the surge in knot adoption highlights the community’s appetite for the unresolved tension between flexibility and conservatism in Bitcoin’s design.

Does knot filter work to reduce so-called “spam” transactions?

Bitcoin Knot supporters often surround the option of running their clients as a way to defend their Bitcoin identity as a currency network. By enabling filters that reject transactions linked to mechanisms that provide specific privacy, such as ordinals, stamps, runes, and even coin joins, Knot users believe they are maintaining rare block space for payments rather than speculative or data-rich activity. This belief is central to the growth of the knot in 2025, and many node operators see it as a form of stewardship for Bitcoin’s long-term health and ease of use.

However, despite these intents, there is little empirical evidence that such filtering significantly reduces the existence of these controversial transaction types on the Bitcoin blockchain. Knots can block certain transactions at the Mempool level, but miners ultimately decide what is included in the block, and most pools do not rely solely on knot policies when building them. As a result, the broader ecosystem of ordinal inscriptions, rune tokens and coinjun style mixes is barely affected and raises questions about the effectiveness of node-level filtering as a meaningful deterrent. Non-knot nodes, and bitcoiners that do not share the ideological perspective of pro-filtered knot node users, typically do not filter transactions from members of the node. If transactions are valid by consensus rules and pay transaction fees, they are treated equally to other valid, valid pay transactions, leading to a route around filters integrated into the knot node.

This problem is exacerbated by the presence of out-of-band transaction channels that members bypass completely. Large miners and pools often accept direct transactions submissions from clients (fees apply). This means that even if the knot node filters out specific activities, these transactions can be communicated directly to the miner. Services like the marathon’s “slipstream” explicitly facilitate this process and provide a route for transactions that are otherwise filtered to find a way to the block. In addition to out-of-band member channels, you need to consider the game theory and profitability incentives themselves that are inherent to Bitcoin mining.

Aside from ocean mining, the Bitcoin mining pool, which implements filters within the node infrastructure, led by Luke Dash Jr. and backed by Jack Dorsey, the co-founder of Twitter (now X), is generally not an ideological one. They are usually willing to include consensus valid transactions that pay the block appropriately whether or not it contains any data. Miners are driven by the need to make profits to stay operational and are willing to leave Satosh on the table. Another issue with the filter story is that even if the knot users don’t include unwanted transactions with their members, the transactions will eventually be included in the memory of non-knot nodes and mined for transaction fees by other miners in the Bitcoin free market, and then ultimately relayed them. This undermines the assumption that Bitcoin transaction mix can be policed ​​with the Mempool filter alone.

This cutting has already fueled controversy, particularly in past conflicts between marine mining and the purses of the Samourai wallet and vortex. Privacy Supporters argued that Knots’ transaction filtering had a negative impact on the Coinjoint Transactions (along with so-called “spam”) that provide privacy, punishing legitimate privacy use cases. Luke Dash Jr. argued that the issue was not one of the censorships, but a fix to what he considered a flaw in the Whirlpool software. He argued that the 46-byte Op_return field was unnecessary, effectively allowed for spam, and drew it in parallel with objections to ordinal inscriptions. He says Bitcoin Knot simply enforced standard limits and the 42-byte cap simply enforced standard limits because it was intentionally designed to reduce spam rather than targeting or disabling privacy-focused tools. While knot users may feel that they are protecting the financial integrity of Bitcoin, the reality is that transaction filtering is limited in its effectiveness in shaping the overall structure of the network given the flexibility of miners’ incentives and decisions to embed data in chains.

Meteor growth of Knot Nordanner and PLEB filter supporters

Over the past few weeks, the debate between Bitcoin Core and Bitcoin Knot has escalated sharply, spilling over platforms like X and Nostr. Both supporters engage in energetic debates dominated by discussions about Op_return, spam filtering, what constitutes “spam,” and the broader role of Bitcoin as a more stringently defined currency network. These exchanges become some of the most prominent topics in the Bitcoin community as participants wrestled with the philosophical and technical direction of the protocol, obscuring price stories and adoption news.

At the heart of the conflict is a knot approach to filter certain types of transactions, such as ordinals, runes, stamps, and more, especially with planned changes in the upcoming V30 release. Knot supporters argue that filtering protects Bitcoin’s rare block space, while core supporters argue that neutrality means allowing valid transactions. The strength of this discrepancy has led to years of ideological divisions into a more sharp focus, reflecting 2017’s “block-sized war” in both tone, competition and scale.

The numbers show how many ground knots have won in this controversy. As of early September 2025, knots accounted for 4,240 of the 23,842 reachable nodes, or roughly 17.78% of the network, a significant increase from just 69 knots in January 2024. What once kept by small groups, fringe clients quickly become meaningful within Bitcoin infrastructure, reconstructing awareness of where ecosystem impacts truly exist.

Bitcoin’s long-term security model relies on replacing gradually decreasing block subsidies with transaction fees as a key incentive for miners to protect their networks. As block rewards cut back half every four years, fee revenues become increasingly important to maintain robust mining activities and protect Bitcoin from potential attacks. It could eliminate valid fee payment transactions and reduce the total fee income of miners, whether they have data in the ordinance, runes, coin joins, or other forms of data, and may weaken the incentives. Some people see filtering that maintains the financial purity of Bitcoin, but broader economic models risk eroding the mechanisms that ensure Bitcoin’s security and longevity.

Paradoxically, the rise of the knot may turn out to be a blessing of Bitcoin’s disguise. For years, almost every reachable node relied on Bitcoin core, creating a monoculture format for client software. Knot’s growing popularity increases diversity within the network, reducing reliance on a single codebase and developer group, even if it is rooted in disagreements. This pluralism can increase resilience and ensures that there is no single implementation that will completely shake up the future of Bitcoin. The spam filter debate remains divisive, but the resulting client distribution could ultimately strengthen one of Bitcoin’s most important values: decentralization.

In just a little under one week, Nvidia (NVDA 1.65%) will report its earnings for Q2 2025.

For the most part, analysts are optimistic about the report, due out after the close of trading on Aug. 27. Consensus forecasts have the semiconductor company growing earnings 48.5% year over year, to $1.01 per share, as insatiable demand for artificial intelligence (AI) chips drives a near-53% rise in revenue to almost $46 billion.

That’s a lot of money Nvidia will be raking in for a single quarter. This is one of the primary reasons why a staggering 58 analysts polled by S&P Global Market Intelligence give Nvidia stock either a “buy” or an “outperform,” or an equivalent rating — versus only one single analyst who says “sell.”

One reason why two analysts are worried about Nvidia

And yet, not everything’s unicorns and rainbows for Nvidia stock. As the final countdown to earnings day begins, two separate Wall Street analysts chimed in Wednesday morning to raise reservations about Nvidia stock and the challenges that lie ahead for it.

First up was Deutsche Bank, where analyst Ross Seymore set a price target of $155 that implies the stock could fall 12% over the next 12 months. Ordinarily, the prospect of a 12% near-term loss in a stock would inspire an analyst to recommend selling that stock. But perhaps fearing to deviate too far from the herd on this popular AI stock, Seymore only reiterated a “hold” rating on Nvidia. (Seymore is still one of only a half-dozen analysts with neutral ratings on Nvidia).

No matter. Whether any one analyst thinks Nvidia is a “buy” or just a “hold” probably shouldn’t concern us as much as why he rates the stock as he does. And in Seymore’s case, the answer couldn’t be clearer:

Writing on StreetInsider.com on Wednesday, Seymore warns that U.S. trade restrictions on semiconductor exports to China will cost Nvidia about $8 billion in “foregone” revenue in Q2. True, a resumption of shipments upon receiving export licenses from the Trump administration should help rectify this situation by Q3. But there’s a cost to that solution — specifically, the Trump Administration’s requirement that, to obtain export licenses, Nvidia must fork over 15% of any revenue it generates in China to the IRS.

With China accounting for roughly $17 billion of Nvidia’s revenue over the last 12 months, that could amount to a $2.6 billion drag on Nvidia’s profits over the next 12 months.

KeyBanc chimes in

Investment bank KeyBanc shares Deutsche Bank’s concerns about Nvidia and China. On the one hand, KeyBanc anticipates Nvidia could book $2 billion to $3 billion in revenue from selling H20 and B40 chips in China next quarter. On the other hand, the banker believes this revenue is unreliable and dependent upon the receipt of export licenses from Washington.

For this reason, KeyBanc warns Nvidia may “exclude direct revenue from China” when giving revenue guidance next week, potentially creating a kind of guidance miss that could send Nvidia shares lower.

KeyBanc also cites the “potential 15% tax on AI exports” from the U.S. side as a risk, and adds that “pressure from the [Chinese] government for its AI providers to use domestic AI chips” could dampen Nvidia’s China revenues even further — adding a third risk that Deutsche didn’t mention!

Finally, some good news

Now, I hope I haven’t painted too bleak a picture for you here. Fact is, despite his reservations, Deutsche analyst Seymore still expects Nvidia to report a “typical” earnings beat next week, exceeding the company’s $45 billion revenue forecast by about $2 billion. Blackwell revenue is ramping, says Seymore, more than doubling sequentially between Q4 2024 and Q1 2025, to $24 billion.

With the prospect of an imminent earnings beat, it makes sense that Seymore would hesitate to recommend selling Nvidia stock — even if he does feel it’s a bit overpriced.

Furthermore, KeyBanc agrees that Blackwell production is ramping, and a new Blackwell Ultra (B300) chip is on the way, potentially boosting revenue even more in Q3. For these and other reasons, KeyBanc not only still rates Nvidia stock “overweight” (i.e., buy). KeyBanc actually raised its price target on the stock to $215 on Wednesday.

So, is Nvidia stock a buy or not?

That’s the real question, isn’t it? Wall Street’s confident Nvidia will “beat” on Q2 next week. It’s just worried that Nvidia will “miss” on guidance for Q3. Longer-term, though, is Nvidia stock a buy or isn’t it?

Here’s how I look at it, and I’ll keep this really simple:

Valued at 4.28 trillion dollars, earning nearly $77 billion in annual profit, and backing that up with roughly $72 billion in annual free cash flow, Nvidia stock costs about 55 times trailing earnings and about 59 times free cash flow. For Nvidia stock to be a clear-cut buy, I’d want to see the stock growing earnings at least 50% annually over the next five years.

The best that Wall Street analysts expect Nvidia to do, however, is 30% annual growth — even with nine out of 10 analysts polled saying Nvidia stock is a buy.

The math here isn’t hard. Nvidia stock is not a buy at this price — but it might be if it sells off after earnings.

Conclusion and Overall Evaluation

What just happened? Industry watchers have been closely monitoring signs of rising prices in consumer technology. Thanks to research by YouTuber Cameron Dougherty, we now have clear evidence of price increases in popular PC accessories. Dougherty has done the legwork by analyzing a broad range of Logitech products, reporting price hikes of up to 25 percent on some of the company’s most sought-after keyboards and mice, among other items.

In his video, Dougherty raises questions about the impact of ongoing tariffs and the future affordability of tech gear in the United States. Flagship products such as the Logitech MX Master 3S mouse and the K400 Plus Wireless Touch Keyboard were among those affected. The latter increased in price from $27.99 to $34.99 – a modest $7 jump that nonetheless represents a significant 25 percent rise.

Dougherty’s findings also note that while some products have become more expensive, others have remained stable or even dropped in price. For instance, the G Pro X Superlight mouse dropped from $159.99 to $149.99.

To verify these claims, Tom’s Hardware conducted its own investigation and corroborated several of Dougherty’s observations. For example, the MX Keys S keyboard is now listed at $130 on Logitech’s official website, reflecting an 18 percent increase. The MX Master 3S mouse has climbed 20 percent, from $100 to $120. The K400 Plus Wireless Touch keyboard’s price hike, though smaller in absolute terms, stands out for its percentage jump.

Notably, these increases have not been accompanied by any public announcement from Logitech. Some items have appeared on sale at major retailers like Amazon, but the discounted prices are still higher than historical norms, suggesting a new baseline has been established.

The reasons behind these changes are complex but appear to be closely tied to the turbulent tariff environment. The Trump administration’s tariffs on imported goods, especially those from China, have sent ripples through the tech industry.

Many manufacturers, including Logitech, rely heavily on Chinese production, leaving them particularly vulnerable to these policy shifts. Earlier this month, Logitech withdrew its financial forecast for the upcoming fiscal year, explicitly citing ongoing uncertainty around tariffs as a driving factor.

While some tariffs have been temporarily paused, those on Chinese imports remain steep, forcing companies to navigate a landscape of unpredictable costs and supply chain disruptions.

Logitech is not alone in adjusting its pricing. Other brands, such as accessory maker Anker which is based in China, have also raised prices on products like chargers, with reported increases of around 18 percent.

Industry experts caution that these adjustments may not be the last, as manufacturers continue to adapt to evolving trade policies and the potential for further escalation in the U.S.-China trade dispute.

Game On? Despite a growing userbase and popularity, macOS still poses significant challenges for true gamers. While alternative solutions exist to ease the burden, Whisky was one of the better compatibility layers that is now about to go dark – because its developer has simply lost interest.

The developer of Whisky recently announced that the project will no longer be actively maintained. Also known as WhiskyWine, Whisky is a user-friendly frontend designed to run Wine’s compatibility layer on macOS.

Like Wine, Whisky is open source, but it also incorporates code from CodeWeavers CrossOver – a commercial product aimed at enhancing Wine’s functionality by offering additional fixes and improved compatibility for running Windows games on Mac systems. CodeWeavers has contributed over 50,000 changes to Wine, making it a major force in the project’s ongoing development.

Whisky will not receive any future releases, except possibly for occasional updates if a macOS upgrade breaks the application. The developer explained that he lost interest in the project, which is time-consuming and provides little financial reward – especially for someone still in school.

Additionally, the developer feels that Whisky hasn’t offered any meaningful contributions to the broader Wine community. Since Whisky is based on CrossOver and doesn’t introduce new improvements of its own, it ultimately falls short.

In fact, the developer described Whisky as having a “parasitic relationship” with CrossOver – potentially harming its profitability. “Without CrossOver, there would be no Wine on Mac,” the programmer stated.

CodeWeavers continues to invest significant time and resources into transforming macOS into a viable gaming platform. CrossOver now includes tools to support the latest DirectX 12 games on Apple’s OS – so much so that Apple even used its open-source code as a foundation for the company’s own Game Porting Toolkit.

Meanwhile, Whisky has simply brought select features from CrossOver and Apple’s toolkit to users under a fully open-source license.

Whisky was a major undertaking for a solo developer, which made the decision to stop active development a difficult one. The programmer is now focused on other projects, including a macOS port of Sonic Unleashed Recompiled, built using Apple’s Metal API. Recompiling old console games is an exciting frontier for retro gaming enthusiasts, though it’s unlikely to replace emulation or virtualization due to the immense effort required to bring each title back to life on modern PCs.

Crypto-focused media outlet Watcher Guru confirmed that its official X account was hacked to promote a fake report claiming Ripple and SWIFT were close to a deal to use XRP in global payment systems.

The unauthorized post went live on March 21 at 2:05 A.M. UTC. It falsely stated that Ripple would soon partner with SWIFT and that billions of XRP had been locked in escrow as liquidity reserves.

The post quickly gained attention and sparked excitement in the XRP community, with many users believing it was true. For context, Bitrue, a prominent pro-XRP crypto exchange, mistakenly shared the fake news, amplifying the confusion.

Shortly after, Watcher Guru clarified the situation, confirming that the post did not come from their team.

According to the media outlet:

“Our X account has been hacked and the previous post (now deleted) was posted by a hacker. We have 2FA enabled and have taken extreme measures to avoid hacks.”

Due to automation, the same false report was also shared on Watcher Guru’s other social media accounts, including Telegram, Facebook, and Discord. The team said the reposting bot pushed the content to all channels before the issue was spotted.

Meanwhile, Watcher Guru stated that the attacker had blocked Ripple’s official X account and that of its CEO Brad Garlinghouse to “presumably slow down a ‘false report’ response from their team.”

This marks the second major breach of a prominent crypto platform on X. Earlier this week, DB News’ X account was hacked and used to spread a fake report about Donald Trump’s TRUMP memecoin and a false BlackRock ETF filing for Hyperliquid.

Understanding the breach

Watcher Guru believes the breach may have started weeks earlier as its team had received a suspicious X link through Telegram on March 5.

According to the team:

“We noticed the link was formatted in a strange way. It was an official X Developer staging site using X’s official domain, however it included a specific path and ‘token’ query string which X links do not normally have.”

Watcher Guru stated that its team flagged the link and contacted X’s Head of Cybersecurity, Christopher Stanley, but received no reply.

Watcher Guru continued that while it cannot confirm the link that caused the hack, the firm noted that its breach resembled that of DB News, another crypto media outlet.

According to Watcher Guru, its account, like DB News, had two-factor authentication enabled, no connected apps, and no API tokens were used to post the false information.

It concluded:

“At this time, we have not yet determined the exact source or method behind the hack. All unauthorized posts have been removed, and our account has been secured. We are contacting X for further clarification.”
