A prominent Bitcoin Ordinals advocate, Leonidas, has proposed building an alternative open-source Bitcoin client aimed at easing protocol-level limits that currently affect Ordinals inscriptions and Runes-style token transfers. The proposal, discussed in a Friday post on X, is framed as a way to reduce what Leonidas calls unnecessary “permission” requirements enforced by widely used node software.

Leonidas’ plan—described as “Bitcoin $DOG Mode”—would, if implemented, increase the maximum individual transaction size and reduce the network’s dust threshold. Supporters argue these changes would make it more practical to package larger token and inscription activity into fewer transactions, while critics have long accused Ordinals and Runes of contributing to “spam” on Bitcoin’s base layer.

Key takeaways

• “Bitcoin $DOG Mode” proposes a new open-source client to relax limits that Leonidas says hinder Ordinals inscriptions and Runes transactions.
• It targets a much higher max transaction size—3.9 million weight units versus Bitcoin Core’s 400,000 WU.
• It would lower the dust limit to 1 satoshi from the current range of 294–546 sats, reducing output padding requirements.
• The approach is positioned as competitive: the client would be an alternative to Bitcoin Core and Bitcoin Knots, with the goal of pressuring broader adoption to loosen restrictions.

What Leonidas says would change

In his announcement on X, Leonidas set out two specific operational tweaks. First, the proposal would lift the maximum allowed size for an individual transaction to 3.9 million weight units, compared with 400,000 WU under Bitcoin Core. Second, it would reduce the dust limit—the minimum UTXO amount considered economically spendable—to 1 satoshi, down from a 294–546 satoshi range.

Leonidas’ stated reasoning is that Bitcoin’s rules and culture are broader than what popular client implementations currently permit. He argues that Bitcoin Core and Bitcoin Knots have spent years applying policies that go beyond what he believes the protocol requires, particularly in ways that complicate how Ordinals and Runes activity is formatted and relayed across nodes.

“Bitcoin Core and Bitcoin Knots have spent years enforcing rules that Bitcoin itself does not have,” Leonidas said in a statement, describing the initiative as a response to what he calls excessive restrictions.

Why transaction limits matter for Ordinals and Runes

Both Ordinals and Runes are often discussed as Bitcoin’s answer to categories of assets usually associated with token standards outside Bitcoin—inscriptions for non-fungible representations and Runes for fungible token-like transfers. Even though they’re controversial, they share a practical challenge: getting complex data and structured token transfers into transactions that fit within standard limits.

Leonidas emphasized that increasing the transaction size ceiling would make it easier for Ordinals users to fit much larger files or collections into a single transaction. Under the proposed settings, he said it could be possible to create transactions that consume a large share of block space—transactions approaching nearly an entire block—without being blocked by client-imposed maximums.

The dust-limit change would also target day-to-day friction. Dust rules determine the smallest outputs that are economical to handle. If dust is too high, users may need to create extra output padding to ensure their transactions get relayed and processed smoothly by default Bitcoin Core nodes. Leonidas’ proposal would reduce that requirement by lowering the economically “uneconomical” floor to 1 satoshi.

From an end-user perspective, those adjustments translate into fewer constraints when forming inscription-heavy or token-heavy transactions—potentially enabling more efficient packaging and less waste in output structure.

Alternative client strategy—and what it would take to move the market

Leonidas positioned $DOG Mode not as a patch to Bitcoin Core, but as an alternative open-source client. In his description, the new client is meant to compete with two of the most widely used Bitcoin node implementations: Bitcoin Core and Bitcoin Knots.

The broader bet is that if enough users run the new client, Bitcoin Core may eventually be forced to reconsider its own policy restrictions in practice. Leonidas said the objective is to build enough adoption that Bitcoin Core would “eventually” have to loosen its stance.

That strategy reflects a key tension in Bitcoin’s ecosystem: software defaults strongly influence what is considered “normal” network behavior. Even when community debate centers on whether certain limitations are truly required by Bitcoin’s fundamentals, the reality for users is that mainstream clients shape what transactors can practically submit and propagate without running into relay or policy friction.

Whether a competing client can achieve the kind of uptake Leonidas is targeting remains unclear. Adoption depends on more than technical changes—it requires trust in the client’s security, compatibility, and network behavior. The proposal’s effectiveness would also hinge on how other nodes in the ecosystem handle and standardize the transactions produced by $DOG Mode.

An ongoing debate over “spam” and Bitcoin’s direction

The move lands in the middle of a continuing community argument. Leonidas’ remarks explicitly tap into a familiar criticism: that Ordinals and Runes can increase on-chain activity by embedding additional data and structures into transactions. Detractors have repeatedly argued that this kind of usage is “spam” that burdens the network and obscures Bitcoin’s purpose.

Supporters generally counter that Bitcoin’s permissionless nature allows diverse usage, and that clients should not restrict how data and token-like activity can be expressed on-chain when the underlying protocol can accommodate it.

Leonidas’ client proposal is essentially a technological expression of that philosophical dispute. By altering parameters around transaction size and dust thresholds, $DOG Mode would aim to make controversial activity easier to execute and easier to propagate—without relying on permission from the dominant clients.

Earlier coverage from Cointelegraph has discussed the conservative node client landscape as part of this broader context, underscoring how different implementations can influence what users can do on Bitcoin without friction.

Earlier Cointelegraph reporting has also highlighted how conservative approaches can restrict certain inscription activity, reinforcing why Leonidas’ focus on client-enforced rules is central to this proposal.

What readers should watch next is whether Leonidas and supporters produce a working open-source implementation of “Bitcoin $DOG Mode,” and—if they do—how quickly it gains traction among users and node operators. Equally important will be whether the proposed parameter changes trigger more explicit policy adjustments from Bitcoin Core or other major clients, or whether the ecosystem continues to split into competing operational norms.

BitPay has secured authorization under the European Union’s Markets in Crypto-Assets (MiCA) framework, allowing the crypto payments company to offer regulated digital asset services across the bloc through its Dutch subsidiary.

According to a press release shared with crypto.news, BitPay B.V. has received authorization as a crypto-asset service provider (CASP) from the Dutch Authority for the Financial Markets (AFM), enabling the company to operate across European Union member states under MiCA’s passporting rules.

The approval allows BitPay to expand regulated crypto payment services across the region, including cryptocurrency payment acceptance, stablecoin-based transactions, and cross-border payment solutions for businesses. Consumers will also gain access to tools for spending and managing digital assets, while partner platforms can support buying, selling, and swapping cryptocurrencies.

Thom de Jong, BitPay’s Chief Compliance Officer Europe, said the authorization strengthens the company’s ability to serve businesses and consumers throughout the EU while reinforcing its compliance-focused approach. He added that MiCA provides a common regulatory framework for responsible digital asset innovation across Europe.

MiCA licensing race reshapes the European market

BitPay joins a growing list of crypto companies that have secured MiCA authorization following the European Union’s July 1 deadline requiring crypto-asset service providers to operate under the new regulatory framework.

Earlier this month, Ripple received full CASP authorization from Luxembourg’s financial regulator after first obtaining preliminary approval in June. Coinbase also selected Luxembourg as its European regulatory base, giving it passporting rights across all 27 EU member states as well as Iceland, Liechtenstein, and Norway.

Not every company completed the licensing process before the deadline. Earlier reports showed Binance withdrew its Greek license application and began limiting services in several European markets after the transition period ended.

Industry observers have also noted that customer migration toward licensed platforms has created new compliance challenges. Bruna Szego, chair of the EU Authority for Anti-Money Laundering and Countering the Financing of Terrorism (AMLA), previously warned that firms onboarding large numbers of new customers must maintain effective anti-money laundering controls while handling increased demand.

BitPay plans further expansion in Europe

From its European base in Amsterdam, BitPay said it intends to support merchants, partners, and consumers as demand for regulated digital asset payments continues to grow. 

“Europe is one of the most important regions for the future of payments,” said Jonathan Arler, Head of Europe at BitPay. 

“From Amsterdam, BitPay is now positioned to support merchants, partners, and consumers as demand grows for practical ways to accept, move, manage, and spend digital assets.”

The company said the authorization also expands its global regulatory footprint, which already includes money transmitter licenses and other approvals in multiple jurisdictions.

 According to BitPay, the additional regulatory coverage will support businesses and consumers as cryptocurrency payments, stablecoin transactions, consumer finance applications, and cross-border settlement become more widely used.

Founded in 2011, BitPay said the MiCA authorization represents the next stage of its European operations. The company also plans to invest further in regional infrastructure and strategic partnerships to expand regulated cryptocurrency payment services across the European Union.

PayPal’s board has determined that a $53 billion takeover proposal from Stripe and Advent International undervalues the company while raising financing and regulatory concerns, even as discussions continue.

Reuters reported that PayPal’s board believes the consortium’s $60.50-per-share offer does not fully capture the value the company could generate if its turnaround plan succeeds, according to a person familiar with the matter. The proposal values PayPal at about $53 billion and represents a premium over the company’s recent trading price.

While the board has not formally responded to the offer, Reuters reported that directors are reviewing both the bid and the possibility of competing proposals before deciding on the company’s next steps. 

Alongside the purchase price, the board is weighing the certainty of financing, possible regulatory obstacles, and the time needed to complete such a transaction, the report said.

Shares of PayPal rose about 2% on Thursday to $56.73.

Earlier this month, Stripe and private equity firm Advent International submitted the joint proposal after first approaching PayPal with Block in April. Reuters previously reported that Block later exited the consortium before the latest offer was presented.

Financing package and deal structure

According to Reuters, JPMorgan and Morgan Stanley have assembled a financing package of roughly $50 billion to back the acquisition, while Stripe and Advent would contribute about $17 billion in equity. Under the proposal, the two companies would jointly own PayPal with equal stakes instead of splitting the business into separate entities.

People familiar with the discussions told Reuters the consortium has also explored possible remedies should antitrust regulators raise concerns. One option under consideration would be to separate PayPal’s Braintree business or certain other assets and transfer them to Advent, where they could be combined with the firm’s existing payments investments, including Nuvei.

Although PayPal has reservations about the current terms, Reuters reported that Stripe and Advent remain interested in reaching an agreement and continue to be viewed as the most serious bidders. The sources added that negotiations are expected to continue and may take time before any outcome becomes clear.

Turnaround plan and crypto business remain in focus

Investors are now looking ahead to PayPal’s July 28 earnings report for evidence that its core checkout business is recovering after the company issued weaker-than-expected guidance earlier this year and warned of slowing momentum in the segment, Reuters reported.

PayPal has been restructuring its operations under CEO Enrique Lores, who took over in March. In April, the company reorganized its business into three divisions covering checkout, Venmo consumer financial services, and payments and crypto. First-quarter revenue rose 7% year over year to $8.35 billion, while payment volume increased 8% on a currency-neutral basis to about $464 billion.

The company’s crypto operations include PayPal USD (PYUSD), a dollar-backed stablecoin issued by Paxos and backed by U.S. dollar deposits, Treasuries and similar cash equivalents. PYUSD recently expanded natively to Polygon through the network’s Open Money Stack, giving businesses access to stablecoin payments, settlement, fiat conversion and compliance services.

The proposed acquisition would also unite PayPal’s crypto payment products with Stripe’s expanding stablecoin infrastructure. Stripe strengthened its blockchain payments business through its roughly $1.1 billion acquisition of stablecoin platform Bridge and has since expanded stablecoin payment services across multiple technology platforms and blockchain networks.

According to Reuters, Advent joined the bid because funding the entire equity portion would be difficult for privately held Stripe alone. The private equity firm’s long history of investments in payment companies, including Worldpay, Vantiv, and Nuvei, could also provide additional flexibility if regulators require changes to the transaction structure. 

Reuters noted that the size of the proposed acquisition and potential antitrust scrutiny could complicate any path to a completed deal.

Strategy has strengthened its cash position to $3 billion as JPMorgan has identified the move alongside steady bitcoin futures inflows as positive developments for Bitcoin despite continued volatility in spot ETF demand.

JPMorgan said in a Wednesday research note that Strategy’s larger U.S. dollar reserves and continued inflows into bitcoin futures have offered encouraging signs for Bitcoin even as spot bitcoin exchange-traded fund flows have turned inconsistent in recent weeks.

The bank said spot Bitcoin ETFs recorded inflows last week before reversing into outflows this week. In contrast, leveraged ETFs linked to Strategy continued attracting positive inflows for a seventh straight week, a trend JPMorgan attributed largely to retail investors.

According to the report, those purchases have supported Strategy’s share price and helped prevent its common stock from trading below the net asset value of the company’s Bitcoin holdings.

Strategy has also increased its cash reserves from $2.55 billion to $3 billion, enough to cover roughly 20 months of dividend payments on its preferred shares. JPMorgan said the larger reserve reduces concerns that the company could eventually need to sell Bitcoin to meet those obligations.

The bank had previously argued that building enough cash to fund two to three years of preferred dividends would ease worries about forced Bitcoin sales. While the analysts said it remains difficult to determine whether the latest cash increase has directly improved investor sentiment, they described the reserve build-up as another constructive signal for Bitcoin.

Bitcoin futures stay firm as ETF flows fluctuate

Alongside the stronger balance sheet, JPMorgan found it encouraging that bitcoin futures continued attracting positive flows this week despite withdrawals from spot Bitcoin ETFs.

The report said buying activity remained positive across both Chicago Mercantile Exchange Bitcoin futures and perpetual futures, markets that JPMorgan considers more representative of institutional participation than retail trading.

The divergence comes as derivatives markets continue to show measured positioning rather than aggressive directional bets. As crypto.news reported on July 17, roughly $1.43 billion worth of Bitcoin and Ethereum options expired with Bitcoin’s put-call ratio at 0.9 and a maximum pain level of $63,000, while Bitcoin remained largely confined to the $60,000-$65,000 range that has held for more than a month.

Greeks.live said Bitcoin gamma exposure remained concentrated around the $64,000 and $70,000 strike prices, indicating traders continue watching those levels for signs of the next larger move. The firm also noted that the latest weekly expiry represented only about 5% of total open interest, limiting the likelihood of a major spot-market reaction.

Earlier this month, JPMorgan said Strategy is not the primary structural risk facing Bitcoin. Instead, the bank argued that broader adoption of permissioned blockchain systems, which operate without relying on public blockchain tokens, could pose a more significant long-term challenge to the digital asset ecosystem.

Strategy, meanwhile, has reaffirmed its commitment to expanding its Bitcoin holdings. President and Chief Executive Officer Phong Le said earlier this week that the company intends to remain Bitcoin’s largest buyer for the foreseeable future and has no plans to change its long-term accumulation strategy.

Le also said Strategy’s balance sheet remains secure and that debt-related risks would only become a consideration if Bitcoin were to fall to around $8,000 to $10,000. He added that the company plans to issue additional STRC preferred shares once they return to their $100 par value, with proceeds potentially allocated to further Bitcoin purchases and additional cash reserves.

Bitcoin was trading near $64,250 at the time of writing, down about 1% over the previous 24 hours.

Circle has integrated its Gateway and Circle Payments Network with Fireblocks, giving institutional customers new ways to manage USDC across blockchains and settle cross-border payments. 

The services are now available directly through Fireblocks’ existing infrastructure, including its transaction controls, approval systems and audit records.

The integration targets trading firms, neobanks and payments companies that use stablecoins for treasury operations and international settlement. According to Fireblocks, stablecoins accounted for 69% of all digital asset transaction volume on its platform during the second quarter of 2026. The company also said USDC became its leading stablecoin earlier this year.

Circle Gateway allows institutions to maintain one virtual USDC balance across supported networks instead of keeping separate pools on each blockchain. Funds can move to supported chains when required, while incoming USDC can automatically return to the unified balance. Fireblocks said the system also reduces the need to hold separate gas tokens for destination networks. 

Circle Payments Network connects USDC with local fiat payouts

The second part of the integration brings Circle Payments Network, or CPN, into the Fireblocks Network for Payments. Customers can send USDC and route payments to recipients who receive local fiat currency through supported providers in more than 50 countries. The companies said settlement can take minutes rather than relying on multi-day correspondent banking processes. 

Meanwhile, Fireblocks will apply its existing policy controls to Gateway transfers and CPN payouts. These include transaction approvals, counterparty lists, sanctions screening and Travel Rule processes. The aim is to let institutions use stablecoin payment rails without building a separate control system for each network or payment corridor.

The rollout builds on a partnership Circle and Fireblocks announced in September 2025. At the time, the companies said Fireblocks customers would gain access to Circle products, including Gateway and CPN, as financial institutions increased their use of stablecoins for payments and treasury operations.

As crypto.news previously reported, Circle expanded CPN in April with Managed Payments, a service designed to let banks and fintech companies use USDC-based settlement without directly managing digital assets or blockchain infrastructure. That service handles parts of the stablecoin process while participating institutions continue sending and receiving fiat currency.

Moreover, Circle added Nium to CPN in May, connecting USDC settlement with payout infrastructure spanning more than 190 countries and 100 currencies. The Fireblocks integration now adds another institutional access point to the network.

Fireblocks said stablecoin transaction volume reached $33 trillion across the wider market in 2025, up 72% year over year. With Gateway and CPN now available inside its platform, customers can manage cross-chain USDC liquidity and fiat payouts under the same operating and compliance controls they already use for other digital asset transactions.

Bitcoin Ordinals advocate Leonidas has proposed building an alternative open-source Bitcoin client designed to loosen specific protocol and relay constraints that, according to its creator, have limited certain “Runes” and “Ordinals” transaction patterns on the network.

In a post on X on Friday, Leonidas outlined what he calls “Bitcoin $DOG Mode,” arguing it would reduce barriers for sending inscriptions and Runes while challenging long-standing default settings used by widely deployed Bitcoin software.

Key takeaways

• Leonidas’ proposed “Bitcoin $DOG Mode” would raise the maximum individual transaction size to 3.9 million weight units (WU), versus Bitcoin Core’s 400,000 WU.
• The client would lower the dust limit to 1 satoshi, from Bitcoin Core’s commonly cited range of 294–546 sats, changing how small outputs can be handled economically.
• Supporters say these changes would make it easier to batch larger Ordinals inscriptions and Runes into single transactions, while critics have called such activity “spam.”
• Leonidas positions the proposal as an alternative to Bitcoin Core and Bitcoin Knots, aiming to force broader policy reconsideration through user adoption.

What Leonidas wants to change

Leonidas’ proposal centers on two rules he says are unnecessarily restrictive relative to what he views as Bitcoin’s intent. First, he targets the maximum size of an individual transaction. In his description, “Bitcoin $DOG Mode” would allow transactions up to 3.9 million WU, compared with Bitcoin Core’s 400,000 WU setting.

Second, he proposes reducing the dust limit to 1 satoshi. Leonidas frames this as a way to eliminate the need for users to pad outputs—an issue associated with whether certain tiny outputs remain economical to include and whether nodes relay them under default policies.

In the same post, Leonidas argued that these adjustments would directly improve usability for projects built around inscriptions and token-like transfers on Bitcoin, including Ordinals and Runes, which have been debated within the broader Bitcoin community.

Why transaction size and dust limits matter

For Ordinals and Runes, the practical challenge is often not just whether the network can technically include data or outputs, but whether standard relay and policy behaviors make certain transaction constructions inconvenient or difficult to broadcast.

Leonidas’ proposed higher transaction size limit would be particularly relevant for users who want to bundle much larger pieces of content into one transaction. The larger the single transaction the client permits, the more data can be placed into one on-chain action—potentially even nearing the capacity of an entire block.

On the relay side, lowering the dust limit is meant to change the economics and mechanics of outputs. Dust limits define the smallest output amounts that can be sent economically, typically tied to whether the network and default node software treat those outputs as non-viable or non-relayable. By pushing the dust threshold down to 1 satoshi, Leonidas suggests users would no longer have to add extra value to make transactions acceptable to default Bitcoin Core nodes.

“Rules that Bitcoin itself does not have,” Leonidas says

Leonidas’ argument is explicitly political as well as technical. He claims that Bitcoin Core and Bitcoin Knots—two of the most commonly used Bitcoin clients—have “spent years enforcing rules that Bitcoin itself does not have,” positioning his $DOG Mode as a corrective.

According to Leonidas, the initiative is not just about supporting Ordinals and Runes, but about removing what he characterizes as “permission” requirements imposed by mainstream software operators and maintainers. He casts the effort as a bid to widen the set of acceptable transaction behaviors without needing users to seek approval through existing default implementations.

While Ordinals and Runes are often described as Bitcoin’s approach to non-fungible and fungible token concepts, the methods have remained controversial. Critics have argued that large-scale inscription or runes-related activity resembles network “spam” and may degrade overall usefulness or impose additional burdens. Leonidas’ proposal directly targets the infrastructure choices that enable or limit such activity, turning a community debate into an engineering proposal.

A strategy to pressure Bitcoin Core policy

Leonidas said “Bitcoin $DOG Mode” is intended to operate as an alternative to Bitcoin Core and Bitcoin Knots. His stated goal goes beyond shipping a fork-like client: he wants to attract enough users that Bitcoin Core would eventually face pressure to loosen its own restrictions.

This approach matters because Bitcoin Core’s policy and configuration choices influence what transactions are easiest to propagate through the network, particularly for nodes using default settings. A competing client with meaningfully different limits could shift practical behavior: if more users and services adopt it, standard assumptions about what transactions can be relayed efficiently might change.

At the same time, the proposal raises questions readers may want to watch closely—especially around where boundaries would end. If larger transaction sizes and lower dust limits become widely used, it could lead to new tradeoffs involving bandwidth, verification workload, and network-level resource consumption. Leonidas’ plan also depends on adoption: without broad usage, Bitcoin Core’s policies may remain unchanged.

Next, investors and builders watching Bitcoin’s on-chain asset ecosystem should pay attention to whether $DOG Mode attracts real-world adoption and how the proposal is received by other parts of the Bitcoin software ecosystem, particularly around relay behavior and policy settings that affect everyday transaction broadcasting.

Airbnb CEO Brian Chesky has confirmed that hackers compromised his X account earlier this week after the profile published a lengthy thread about blockchain-based real-world asset tokenization. 

The posts later disappeared, and Chesky has now responded with a joke about the unexpected audience the incident brought to his account.

In a July 17 post on X, Chesky wrote, “To the person who hacked my account earlier this week: thanks for all the new crypto followers.” He then added, “To my new crypto followers: I’m going to be a very disappointing follow.” His statement confirmed that the earlier tokenization posts did not represent commentary he intended to publish.

Chesky confirms hack after unusual tokenization thread

The deleted thread attracted attention because it presented detailed arguments about tokenized real-world assets rather than promoting Airbnb’s core business. It discussed blockchain-based ownership and financial markets in a way that initially led some observers and publications to treat the posts as genuine comments from the Airbnb chief.

According to Fortune’s report on the incident, Airbnb treated the episode as a high-profile account compromise and moved to secure the profile with X. However, the nature of the posts caused confusion because the thread focused on tokenization rather than pushing a meme coin, fake presale or cryptocurrency giveaway.

The episode differs from many recent social media hacks linked directly to token schemes. As crypto.news reported this week, attackers also compromised SpaceX’s X presence in an incident linked to the SCATMAN token, renewing concerns about criminals using trusted brands to attract crypto traders.

Earlier, as crypto.news reported in May, hackers used Keith Gill’s verified Roaring Kitty account to promote and dump a Solana-based token. The incident reportedly left traders with $2.8 million in losses after users trusted posts coming from the well-known market personality’s account.

By contrast, available reports have not identified a token sale, wallet-draining link or fraudulent giveaway connected to Chesky’s deleted posts. Instead, the compromised account published commentary that users could have mistaken for a genuine shift in the Airbnb CEO’s public position on crypto. That makes the episode different from attacks built around immediate token promotion.

High-profile X profiles remain attractive targets because their established audiences can give unfamiliar crypto claims instant credibility. As previously reported by crypto.news, attackers have compromised accounts belonging to executives, companies, entertainers and market personalities to promote fraudulent tokens, fake airdrops and phishing links.
