I've been hesitating to post something like this at the risk of being canceled, but whatever, here it goes: Back in the earlier Bitcoin days (2013 for me), we often thought of altcoins as a sort of testnet. Good ideas that were implemented in certain altcoins may, eventually, after many years, arrive to Bitcoin as protocol improvements. Most Bitcoiners were at some point in their journey interested in altcoins. Many still are. Toxic maximalism only arrived later. There's an element to this toxic maximalism today, as I observe from the Core vs Knots debate, that says Bitcoin is perfect as is, it should begin to ossify, and all non-financial transactions are spam. I think this is a dangerous point of view. First, Bitcoin is an Internet protocol, and obviously cannot ever ossify. The most obvious example is quantum computing – if or when that happens, Bitcoin will need a protocol upgrade. Hopefully this upgrade will happen before quantum computing is viable. Second, re altcoins: Bitcoin has already learned a lot and is continuing to learn from experiments on altcoins. Calling them "shitcoiners" is nice for your social engagement and stirring up an angry mob. But here's a list of some things that started in altcoins and is now on Bitcoin, or is useful to Bitcoin, or is being worked on in Bitcoin related projects: - Namecoin and colored coins inspired the creation of OP_RETURN. - SegWit was implemented on Litecoin before it came to Bitcoin. - Ring signatures and stealth addresses, pioneered by Monero, influenced Bitcoin privacy research and concepts like scriptless scripts and Silent Payments. - Zero-knowledge proofs (Zcash and beyond) accelerated exploration of zk-based verification and client proofs for Bitcoin. - MimbleWimble introduced new ways to aggregate and compress transactions – ideas that informed work on CoinJoin efficiency, CTV, and general scalability discussions. - Utreexo, which is promising tech and has been discussed at Bitdevs meetups, implemented on Siacoin this year. In my opinion, Bitcoin Core developers should be aware of all developments in the industry and looking to bring the best technology to Bitcoin, in a slow and methodical way. Third, what is spam? I genuinely do not know what spam is. I've heard Knots supporters say that spam is any kind of "non-financial transaction" – but this is a slippery slope. Let's talk about BIP47, for example, which enables reusable payment codes (like PayNym). BIP47 notification transactions include an OP_RETURN output. Does this mean payment codes are considered spam by Knots supporters? Knots supporters might say to that "no, of course not, they use tiny amounts of data anyway, so it's okay if we just restrict the maximum size of an OP_RETURN." So what stops a "scammer" from doing multiple smaller transactions then? And what if I develop a better privacy protocol that requires larger OP_RETURNs than allowed? Do I have to go beg the Core developers to change the defaults? Is it a "non-financial" transaction? To be even more controversial – back when I got into Bitcoin, I liked the idea of everything converging into Bitcoin. Bitcoin's proof of work will continue consuming more and more computing resources (as Saylor and many others rightfully say). The Bitcoin network and protocol will be the most secure, decentralized, resilient protocol in the world. Well then, you can't have it both ways – why are you averse to everyone coming and building on our open, decentralized protocol? I thought we cared about freedom and sovereignty. I thought we wanted a healthy fee market. I thought we are worried about what happens after the last block reward is mined. I thought we want full blocks. Now I hear Knots supporters saying "get away from our Bitcoin, our perfect money, go do your own thing, do your own blockchain." Why aren't we all saying "come build on Bitcoin?" As technology progresses, and as there is demand for more tech to be built on Bitcoin, Core devs have historically upgraded the protocol (slowly and carefully). Lightning, for example, was the culmination of years of Core protocol work: 2016: CSV, relative timelocks → channel mechanics 2017: SegWit → malleability fix & efficiency 2018: Bech32 → cleaner Lightning addresses 2021: Taproot → more private, advanced channels Lightning would have never happened if we had ossified the protocol. You want to scale Bitcoin to 10 billion users? Then you'd be insane to ossify the protocol. So I'm saying it, loud and clear. I want everything built on Bitcoin. I want the Bitcoin network to be the most important and resilient network on Earth, and I want all value to flow into Bitcoin. I want to enable everyone to permissionlessly build on Bitcoin. And I want the Core devs to continuously improve the protocol. Thanks for reading.

Why Ledger is really killing the Nano S. Ledger had announced back in 2022 that they were phasing out the Nano S, and has now finally confirmed that 2025 is the last year the device will receive firmware and app updates. If you grab your Nano S out of a drawer in late 2026, it might not work with the apps you are using, or there may be an unpatched vulnerability. This means that, effectively, anyone who owns a Nano S must upgrade or risk loss of funds. There’s been rightful uproar on X, but also some defending Ledger. The defenders argue that: 1) The Nano S is old. It’s been on the market since 2016. 2) It’s prone to breaking or malfunctioning after owning for several years. 3) New Ledger devices, including the Nano S Plus and Stax + Flex, are much better in terms of memory and performance. While these arguments are true, they miss a few key points. First, Ledger sold the Nano S until Q1 2022. This means that many customers purchased in 2022, and have only owned their devices for just over three years. This is barely any time in the tech world. Apple, for example, is still updating 6-year-old devices to iOS 26 (iPhone 11). Second, this is a hardware wallet, and basic security updates are important. User expectations for hardware wallets should be higher than for a smartphone. Apple, for example, typically releases security updates for ~10 years, long after it stops updating iOS. There’s no technical reason why a 10-year-old Ledger Nano S should not be able to receive security updates. Third, apps on Ledger are open source and could be community-maintained. The Bitcoin app, Ethereum app, and so on are all open source. There’s no technical reason that Ledger can’t simply fork these apps and maintain a separate version for the Nano S that contains less frequent, more modest updates. Or, if Ledger does not want to maintain it themselves, they can still allow the community to maintain them. Unfortunately, the Ledger app platform is a walled garden – and only Ledger can approve apps that are listed in Ledger Live. Four, there is nothing fundamentally broken with the Nano S. It just has a lot less memory and can do less than the newer Ledger devices. Millions of crypto users own Nano S devices. It makes no sense to stop accepting “new application submissions, feature enhancements, or app updates” from developers. Ledger hasn’t clearly explained why they’re ending support – just vague references to memory constraints. In my opinion, Ledger is taking this dramatic action to push users to upgrade to their newer devices. If I had to guess (I have no insider information), Nano S represents at least half of their 7.5 million devices sold. I’d guess around 4 million Nano S devices are in the wild. Converting these customers to newer devices would represent well over half a billion dollars of potential revenue. Ledger is also using uncertain language in their announcement, potentially meant to spark user concern and confusion. Ledger instructs developers in yesterday’s update to tell their communities that “continued full support for your blockchain app/wallet/service on the Nano S may not be guaranteed.” This lack of clarity is clearly causing user concern and panic, as as evidenced by reactions on X. This is the danger of closed source hardware, running a closed source operating system, with a walled garden app platform. Developers have no control. They need permission from Ledger to do anything. They can’t review the firmware code and report or fix bugs. They can’t develop an app without going through the approval process. They can’t customize the UI of their app; they are stuck with severely limited capabilities offered by the OS. To Ledger users and developers: you are not stuck. A better way is coming soon. Our new @FOUNDATIONdvcs Passport Prime is fully open source, assembled in the USA, and runs KeyOS – enabling an open, permissionless app platform. We are already partnered with @cakewallet for the first app, and we are onboarding new app partners as we speak. Passport Prime is shipping in the coming weeks to our Early Access users. We will soon be announcing an easy way for Ledger users to seamlessly switch to Passport Prime and maintain all functionality. Stay tuned!
