Jameson Lopp has been on the front lines of the battle between technologists and those who want to preserve Bitcoin as it is since the scaling debates of 2015–2017.
The topic arouses such passion that many suspect it was a disgruntled Bitcoiner opponent who called down an armed SWAT team to his home, leading him to famously go underground.
Lopp blamed the 2017 incident on the“same old same old: Bitcoin philosophy and scaling debate arguments. A few of the more extreme cases think I’m some kind of manipulative monster.”
Dear anonymous coward who just sent dozens of cops w/ rifles to my house w/a false hostage situation report: I am not so easily intimidated.
Lopp, who is currently the chief technology officer for decentralized wallet service Casa, is an advocate for cautious progress who commands respect among the Bitcoin community.
Speaking from an undisclosed location, Lopp says he worries the backlash against Ordinals NFTs might result in lower support for much-needed future upgrades. Ordinals were largely an unexpected result of the 2021 Taproot soft fork.
“The problem that I see is that there’s a lot of ossification proponents out there. And they’re pointing at Ordinals and inscriptions and saying, ‘You see, this is what happens when you change the protocol. It gets abused and used in ways that were not intended,’” he says.
But Lopp says the alternative is every bit as risky. He has carefully considered the problem of Bitcoin’s “ossification” — where the network becomes so big “it kind of gets crushed under its own weight and unable to change itself.”

Lopp uses email as an example of an internet protocol that ossified in the 1990s, leaving it with little ability to deal with the massive volumes of spam that subsequently arose.
Instead, corporations constructed expensive centralized reputation services on top to sort out spam from legit emails, and today, large numbers of emails that don’t comply with the arcane rules of the systems simply disappear into a black hole. And users are still deluged with spam.
“As of today, something like 90% of all email users are captured by five corporations. So, I think we have to ask ourselves: Is that the mainstream adoption of Bitcoin that we want to see? And if not, then what do we need to do to prevent that?”
For Lopp, scaling Bitcoin — something he’s been agitating for, for years — remains the big challenge as the Lightning Network is “not going to fix everything.”
“If you talk to any of the developers, who’re pretty deep into the protocol, you’ll be hard-pressed to find any of them who think that we should ossify the protocol now. There’s so much work to be done.”
“Honestly, I don’t know how much time we have left to do that.”
Historically, Lopp’s company Casa has been solely focused on Bitcoin, but last month, it outraged puritans on social media by adding Ethereum to its multisignature self-custody solutions. It highlights the fact Bitcoin has a fast-growing challenger snapping at its heels if it lets up the pace.

Who is Jameson Lopp?
Lopp grew up in a “fairly typical Southern American conservative household” in North Carolina, where his father’s side of the family has lived since the 1700s. It was clear from early on that he was super bright, and his parents pushed him hard to achieve great things at school.
“I read probably several grades above my reading level, and I read all the time. I had a special exemption at the library to check out more books than you are normally allowed to just because I was going through such a high volume of them.”
Placed into high-level courses, he often wound up sitting on his own doing separate assignments from the rest of the class, something of a “social outcast.”
“On the social side, I would just get even more awkwardness and sort of abuse because I would sometimes use vocabulary that nobody else was using, and they were like, you know, ‘Who is this alien guy?’”
Lopp ended up joining Mensa in 2010, mainly to see if he could pass the test requiring an IQ in the top 2%. Naturally, he set up a Mensa Bitcoin special interest group, though he says super-smart people don’t necessarily get Bitcoin any faster than anyone else and points to the dismissive reaction to Satoshi’s original announcement about Bitcoin.
“The people who were responding to that email were not stupid. They were incredibly intelligent people. But if you’re intelligent enough, you can always find reasons why something won’t work.”
Coming of age
After school, Lopp headed to study computer science at the “very liberal” University of North Carolina at Chapel Hill. Brought up to be a very conservative Republican, he says university “swung my perspective a little bit more outside of the sort of family and household standards that I had been used to.” He ended up voting for Obama in 2008, Libertarian in the following election, and now believes he can have more impact building decentralized financial infrastructure than voting.
“These days, I view politics at a very arm’s length amused perspective.”
He worked in email marketing for years in one of the tech areas near Raleigh, moving up from working on the web app to large-scale data analysis. Like most people in tech, he read about Bitcoin a few times and dismissed it as “nerd money that was going to end badly” before finally reading the white paper in 2012.
“I was just blown away,” he says, noting that Satoshi approached the double-spending and Byzantine generals problem from the exact opposite direction of the “performance and efficiency” mindset Lopp had been taught.
“When I read the white paper and I saw the solution to the problem, I was amazed because it was both elegant and ass-backward,” he says.
“The solution was to make everything really, really expensive in terms of resource usage. I was like, wow, I never in a million years would have thought to try that because it just goes against our nature as computer scientists.”

Bitcoiners back then were primarily libertarians, cypherpunks and crypto-anarchists, and the chance to find an alternate way forward was part of the appeal.
“We can build alternative power structures, alternative systems that don’t rely upon any of the existing infrastructure. And basically, we can create our own rules for how these systems should operate.”
Lopp forks Bitcoin Core
Within two years, Lopp had created a fork of Bitcoin Core called Statoshi to “bring more transparency and understanding to the internal operations of a Bitcoin node.” He applied for a grant from the Bitcoin Foundation to work full time on the project but never heard back. Five years later, he discovered he’d been successful, but the foundation fell apart before he received any money.
Lopp also applied to work at Coinbase in 2015 and “never even got an interview,” but his work on Statoshi did land him a gig running the nodes for institutional custody and infrastructure provider BitGo. He also began to nurture his public profile, ramping up his research and writing — he’s written for CoinDesk, Cointelegraph and Forbes — tweeting more often, organizing Meetups and presenting at events. He’s now a regular at conferences around the world, but it wasn’t easy to start.
“I’m definitely an introvert, though you wouldn’t know it because I do all of these public speaking events. But that took a lot of practice to do.”

Lopp says the block size wars (2015–2017) was the period when he started to become really well-known in Bitcoiner circles. Initially, he was on the big blocks side, writing an article in 2015 calling for an increase in the 1MB size of blocks to increase capacity and suggesting blocks may one day hit 10GB. He also supported the Bitcoin XT fork of Bitcoin Core, which ended up part of Bitcoin Cash.
“That was really a result of what I had been doing as an engineer for the past decade,” he says, adding that he’d spend much of each year prepping for the Black Friday and Cyber Monday sales because “if you couldn’t handle that, then it would be a bad user experience, you would lose customers, you would lose money, and the business would not grow as quickly.” He didn’t want Bitcoin to lose potential users through a bad experience with the slow, expensive blockchain.
However, his perspective started to change when he realized the impact bigger blocks would have on his own work at BitGo, writing services that talked to the nodes.
“I started to see the opposite side of the argument,” he explains. “Even with these ‘tiny’ 1MB blocks, it was quite challenging for me to write services that could ingest all of this blockchain data at a very fast pace.”
It took weeks sometimes to get a new indexing service up and running from scratch, and doubling or tripling the block size would require exponentially more resources “to the point where only the largest enterprises who had a lot of money to throw at this problem would even be able to run the nodes and the services on top of them.”
So, while Lopp ended up strongly supporting SegWit as a practical solution and thinks Bitcoin is superior to any other cryptocurrency as “sound money,” he also sees room for experimentation on other protocols, and on Bitcoin.
“A lot of people get very ideological and, in some cases, puritanical about this stuff,” he says. “Bitcoin is not a kitchen sink type of protocol there. There’s a lot of things that you can’t do on Bitcoin that you can do with other protocols.”
Su Casa, mi Casa
Lopp joined the decentralized Bitcoin self-custody service Casa in 2018 and was soon promoted to chief technology officer. He also has the title of co-founder. Casa is an alternative to centralized custodians and offers a range of multisignature wallet plans that enable users to avoid losing their funds in security incidents and to recover lost or stolen keys.
Casa began support for Ethereum last month and claims it’s the first company to enable self-custody of both Bitcoin and Ether with up to five keys for distributed security. ERC-20 and NFT support is in the works.
“Obviously, there were a few clients who fell into the sort of extreme Bitcoin-only camp who went their own way,” says Lopp, adding that this was expected. “Really, it’s this loud, tiny minority that can seem a lot bigger than they are if you’re on social media. But in reality, I would say most of our clients and most Bitcoiners, in general, are pretty moderate and kind of apathetic about all of the drama.”
He says the decision resulted from user demand because many existing clients “do have more diverse portfolios, and they want to have that same level of security for assets other than Bitcoin.”
The loud, tiny minority goes SWATing
The famous SWATing incident happened after his views began to evolve. A 911 caller claimed to be holed up at Lopp’s house with hostages, having already shot someone.
“By my voice, you can tell I’m not in a mental health state right now. I’m on drugs. I’m all over the place. I don’t know what to do. […] If I don’t get $60,000, I’m going to blow the whole fucking block up.”
Heavily armed cops arrived at his home, guns drawn. Lopp wasn’t home at the time and arrived to find his neighborhood shut down and crawling with dozens of patrol units, a SWAT team, a mobile command post, a fire truck and a paramedic. He had a conversation with a cop to find out what happened, not realizing he was the suspect.

Following the incident, Lopp tweeted a video of himself firing off an AR-15 rifle as a warning to anyone trying to find him.
The incident also inspired Lopp’s radical privacy experiment to live off the grid and off the radar of the authorities. Apart from standard stuff like using VPNs, private mailboxes and using fake names, it also involved setting up a bunch of limited liability companies to apply for bank accounts and credit cards one step removed. He mainly spent cash, used burner phone numbers and even bought “the crappiest, cheapest hole in the wall I could find that has a physical mailbox” as a physical address to get a driver’s license.
“I determined that the amount of effort and especially money that is required to do it is going to price almost everybody out of doing this,” he says, adding the fact that you have to lie to everyone was also likely to deter people from trying it.
“Everyone in my physical proximity, my neighbors, they only know my pseudonym. And you know, I have my backstory, and I literally had to create this whole alternate persona, but not so different, it would be difficult for me to make it believable. So, like, I’m still a software engineer who knows a lot about security.”
Lopp maintains a GitHub list of “known physical Bitcoin attacks,” which spans from Hal Finney getting SWATed in December 2014 to a couple in Queens, New York who in mid July were mugged by assailants disguised as FBI agents that stole their car, $40,000 in cash and their crypto.
The No. 1 lesson to take from the list is that the fewer people who know they can rob you of your crypto by threatening you with a $5 wrench, the better. So it’s interesting to learn that prior to his SWATing, Lopp used to drive around in a flashy Lotus Elise with a BITCOIN license plate, basically inviting attacks.
Although many people thought it was a Lamborghini, Lopp says that “it was actually a salvage title car that I got for $20,000.” He eventually sold it, but he has the BITCOIN license plate hanging on the wall behind him during our interview as a memento. These days, Lopp drives “extremely common vehicles that are mass-produced by the millions.”

Future progress for Bitcoin
Pushing for progress on Bitcoin while not destroying all of the things Bitcoiners hold dear has always been a thorny problem. Roger “Bitcoin Jesus” Ver couldn’t solve it and went off with the Bitcoin Cash camp, who then split off with Craig “No, I really am Satoshi” Wright heading up Bitcoin SV.
There are also Bitcoiners trying to change it from within, like Eric Wall and Udi Wertheimer, who have embraced Ordinals. Wall is also investigating scaling Bitcoin using the same zero-knowledge proof technology being used to scale Ethereum via Starknet.
Lopp says he’s focused on a variety of improvements that can be made to “let people start building more outside of the base protocol.”
“You don’t need to go through the same onerous process to develop on a second layer, you don’t have to make these sweeping consensus changes that are really risky,” he explains.
“That’s one of the reasons why I want to see a lot more second layers other than just Lightning. I want to see more sidechains, drive chains, rollups, so on and so forth. Because I think that that is going to enable more innovation, more experimentation.”

The acting chair of the Federal Deposit Insurance Corporation (FDIC), the regulatory body overseeing banks in the US, is reportedly considering guidance for tokenized deposit insurance and plans to launch an application process for stablecoins by year’s end.
Acting FDIC Chair Travis Hill, who has made bullish statements about tokenization in the past, told the Federal Reserve Bank of Philadelphia’s Fintech Conference on Thursday that the regulator will eventually release guidance around tokenized deposit insurance, according to reports.
The FDIC protects depositors in the event of a bank failure and insures money in accounts at banks that are insured by the regulator.
“My view for a long time has been that a deposit is a deposit. Moving a deposit from a traditional-finance world to a blockchain or distributed-ledger world shouldn’t change the legal nature of it,” Hill said, as reported by Bloomberg.
Excluding stablecoins, the total value of tokenized real-world assets surpassed $24 billion in the first half of the year, with private credit and US Treasurys making up the bulk of the market, according to a report by RedStone.
BlackRock, the world’s largest asset manager, is one of the most prominent players in the space and launched a tokenized money market fund called BUIDL in 2024.
Stablecoin application regime by the end of the year
At the same time, Hill reportedly announced the agency is also working on a regime for stablecoin issuance and expects to issue a proposal for an application process by the end of 2025 as part of its duties in crafting rules under the GENIUS Act, according to Law360.
He said it’s still too early to know how many institutions will be interested, but the FDIC staff is working on the standards around capital requirements, reserve requirements and risk management for FDIC-regulated stablecoin issuers.
Stablecoins have also been a high-growth area, with banks worldwide exploring this technology. The market capitalization of stablecoins is approximately $305 billion as of Friday, according to blockchain analytics platform DefiLlama.

Sir Keir Starmer and Rachel Reeves have scrapped plans to break their manifesto pledge and raise income tax rates in a massive U-turn less than two weeks from the budget.
I understand Downing Street has backed down amid fears about the backlash from disgruntled MPs and voters.
The Treasury and Number 10 declined to comment.
The decision is a massive about-turn. In a news conference last week, the chancellor appeared to pave the way for manifesto-breaking tax rises in the budget on 26 November.

‘Aren’t you making a mockery of voters?’
The decision to backtrack was communicated to the Office for Budget Responsibility on Wednesday in a submission of “major measures”, according to the Financial Times.
The chancellor will now have to fill an estimated £30bn black hole with a series of narrower tax-raising measures and is also expected to freeze income tax thresholds for another two years beyond 2028, which should raise about £8bn.
Tory shadow business secretary Andrew Griffith said: “We’ve had the longest ever run-up to a budget, damaging the economy with uncertainty, and yet – with just days to go – it is clear there is chaos in No 10 and No 11.”
How did we get here?
For weeks, the government has been working up options to break the manifesto pledge not to raise income tax, national insurance or VAT on working people.
I was told only this week the option being worked up was to do a combination of tax rises and action on the two-child benefit cap in order for the prime minister to be able to argue that in breaking his manifesto pledges, he is trying his hardest to protect the poorest in society and those “working people” he has spoken of so endlessly.

Ed Conway on the chancellor’s options
But days ago, officials and ministers were working on a proposal to lift the basic rate of income tax – perhaps by 2p – and then simultaneously cut national insurance contributions for those on the basic rate of income tax (those who earn up to £50,000 a year).
That way the chancellor can raise several billion in tax from those with the “broadest shoulders” – higher-rate taxpayers and pensioners or landlords, while also trying to protect “working people” earning salaries under £50,000 a year.
The chancellor was also going to take action on the two-child benefit cap in response to growing demand from the party to take action on child poverty. It is unclear whether those plans will now be shelved given the U-turn on income tax.
A rough week for the PM
The change of plan comes after the prime minister found himself engulfed in a leadership crisis after his allies warned rivals that he would fight any attempted post-budget coup.
It triggered a briefing war between Wes Streeting and anonymous Starmer allies attacking the health secretary as the chief traitor.

But the saga has further damaged Sir Keir and increased concerns among MPs about his suitability to lead Labour into the next general election.
Insiders clearly concluded that the ill mood in the party, coupled with the recent hits to the PM’s political capital, makes manifesto-breaking tax rises simply too risky right now.
But it also adds to a sense of chaos, given the chancellor publicly pitch-rolled tax rises in last week’s news conference.
The home secretary is set to unveil sweeping reforms to tackle illegal immigration, as she considers potential changes to human rights law.
Shabana Mahmood will announce on Monday a series of measures to make it easier to remove and deport illegal migrants, and reduce the “pull factors” that make the UK attractive to asylum seekers.
The Home Office said they would be the “most sweeping reforms to tackle illegal migration in modern times”.
She is said to believe that “excessive generosity and ease of remaining” in the UK, along with systemic barriers, has made deportations extremely difficult, The Times reported.
It is understood that many of the changes set to be proposed by the home secretary will be modelled on the Danish system, under which 95% of failed asylum seekers are deported.
Denmark has tighter rules on family reunions, and restricts some refugees to a temporary stay.

UK considers copying Denmark’s immigration system
Ms Mahmood is also mulling reforms to the European Convention on Human Rights and human rights law to “end the abuse of the system that leads to unjustified claims to delay or stop deportations”, a Home Office source said.
The overhaul of modern slavery laws will require migrants to make a claim that they have been a victim as soon as they arrive in the UK, rather than allowing them to raise it unexpectedly later on, which has resulted in delayed deportations, The Telegraph reported.
The number of offences qualifying foreign criminals for automatic removal is also set to be increased, the paper said.
And judges are expected to be required to prioritise public safety over claims from migrants that deporting them would breach their family rights or put them at risk of “inhuman” treatment if they were returned to their home country.

Deportations are up – but so are boat crossings
Ahead of next week’s announcements, the Home Office released new figures showing 48,560 people have been removed from the UK since Labour came to power.
The figure, which includes failed asylum seekers, foreign criminals and others with no right to be in the UK, is a 23% increase compared to the 16 months before last year’s election.
Ms Mahmood said: “We’ve ramped up enforcement, deported foreign criminals from our streets, and saved taxpayers millions.
However, small boat crossings continue to rise – 39,075 people have made the journey so far this year, according to Home Office figures.
That is an increase of 19% on the same point in 2024 and up 43% on 2023, but remains 5% lower than the equivalent point in 2022, which remains the peak year for crossings.
