As bad as the multisig UX is, I still can't sleep well at night with singlesig. I've developed a tool (presented at @TABConf) that's aimed at improving the multisig UX experience. It's just a start, but it will greatly simplify multisig as it matures. Keylay.org

I feel like there needs to be a podcast about security. We could all benefit from leveling up the average person on the topic. Cryptography Keys Curves Systems Network Hacking All that stuff but explained in a superrrrrr friendly analogy driven way. Yay or nay? That feels value adding. Nothing to sell you but knowledge.

BIP-39 maps 11 bits per word. A 12-word seed encodes 128 bits of entropy. A 24-word seed encodes 256 bits. The extra 128 bits do not reach the private key in any meaningful way, because Bitcoin private keys have a security level of 128 bits regardless of seed length. The ECDSA curve order is 256 bits, but brute-forcing a Bitcoin address via RIPEMD-160 collapses that to 160-bit preimage space, and the actual attack surface against a secp256k1 key sits at roughly 128 bits of effective security.

And just like that, the idea of building air-gapped Bitcoin signing devices from commodity hardware doesn’t look so paranoid after all Curious about those options? @SeedSigner @selfcustodykrux

In 2015, a Senate inquiry recorded Bitcoin businesses complaining that banks were treating Bitcoin firms as a blanket high-risk category and refusing services. ASIC told that inquiry it was aware banks were ceasing relationships with Bitcoin businesses but had no power to intervene. By 2021, the problem was even more explicit. Bitcoin-only exchanges told a Senate committee that banks could freeze or close accounts with little notice, provide no reason, and leave businesses with effectively no regulatory recourse. The committee concluded that de-banking was harming competition and creating concentration risk for the digital-assets sector. In 2022–23, government formally recognised de-banking of digital currency exchanges, fintechs and remitters as a serious problem and commissioned the CFR to recommend responses. Now, in 2026, the RBA’s payments-regulation review is recording the structural mechanism beneath those complaints: smaller providers being dependent on sponsors, access potentially being withdrawn at short notice, weak bargaining power, few alternatives and calls for transparency and appeal mechanisms. The RBA is now considering which of these issues should become regulatory priorities by the end of 2026. It’s been more than 10 years with nothing of substance having been done Australians continue to get debanked, their transfers throttled, or outright refused. Australians deserve better banking.

The world's attitude to Bitcoin mining is changing rapidly For example, I just spent the weekend visiting 3 landfills where that country's government's environmental ministry identified that Bitcoin mining is the best solution to remove their hazardous methane emissions

Things i learned today ..
In 1690, the English navy lost badly to the French at the Battle of Beachy Head. King William III needed a new fleet, and the Crown's credit was so poor that nobody wanted to lend to it. Charles II had defaulted on the goldsmiths only eighteen years earlier, and London had a long memory. A Scottish merchant named William Paterson proposed a solution. A group of private investors would lend the government £1.2 million at 8 percent interest. In return, they would be incorporated as a bank with the right to take deposits and issue notes. The subscription filled in about twelve days, and in July 1694 the Bank of England received its charter. It was not created to protect savers or keep prices stable. It was created to fund a war. Here is the part worth sitting with. The bank's capital was lent straight to the government, and the government's promise to repay sat behind the notes the bank issued. A loan to the state became money that circulated across London. The goldsmiths had stretched receipts beyond their gold. The Bank of England went further and turned government debt itself into money. That arrangement became the template for central banking around the world, and the beginning of what we now call the national debt. So who controlled the ledger now? Not nature, and no longer just the goldsmith down the street. A private bank and the Crown, bound together by mutual need. The government got easier access to money for wars. The bankers got interest and a privileged seat at the centre of the system. Savers got paper. The partnership suited both sides so well that it has never really ended. Tomorrow, what happens when everyone wants their money back at once. Follow and ring the 🔔 on our profile so you don't miss a day.

if secure elements can't do on chip secp256k1 sigs and instead store the encrypted sk, which is then decrypted into memory and used for signing; can someone please tell me why hwws are using SEs at all? is it more security theatre than actual protection?

Yesterday I wrote "Bitcoin (mining) as an energy solution, is the Trojan horse for Bitcoin as a monetary solution" Here's the receipts behind the tweet: 1. Bitcoin-as-an-energy solution is the subject of >90% of peer reviewed journals >75% of Cambridge's report is on Bitcoin mining 2. Of countries forming National Bitcoin Reserves (other than by confiscation) > 90% have done so using Bitcoin mining (only El Salvador purchased Bitcoin) 3. Of people routinely talking to political leaders about Bitcoin (including Prince Filip, Adam Back, myself) almost all of the leaders want to talk about Bitcoin and energy (versus a much more muted response to "Bitcoin and money") 4. My keynote on how Bitcoin solves an energy problem at PlanB had a small Bitcoin audience, but outside the conference was seen by twice the number of people as the next most viewed talk Bitcoin is a fire waiting to burn. The Bitcoin-as-money conversation is the big log in the fire. It's the ultimate place we want to end up. But it's not the starting point. We've been trying to start a fire by holding a match to a big log. Bitcoin mining is the kindling, it's the fire starter, because it solves so many energy problems that people have, and political leaders are struggling to find solutions to, right now! Once Bitcoin mining creates acceptance of Bitcoin, from there it will be so much easier for the big log of Bitcoin-as-money to catch alight.

The surcharge is gone. The cost isn't. From today, card fees are built into every price. Pay cash? You're paying for the card network. Insert your debit card? You're paying for someone else's rewards points. The RBA calls this transparency. It's the opposite. The $1.6bn in fees are still there. You just can't see it.

I spent 5 years funding new technology that could have social and environmental impact I don't do that any more I realized we don't use the technologies we already have, and using them is 10x faster and 5x less risky. For example, we already have the tech we need to obviate gas peaker plants, accelerate renewable transition, mitigate landfill methane at scale and end the practice of gas flaring for good. Better still, it is a single technology: Bitcoin mining And the world is slowly starting to understand that it might just be the most important force for environmental good we've ever had.

I want to take a moment to honour the innovation happening across the Bitcoin industry in Australia 🇦🇺 For a country of just 27 million people, we have: 5 Bitcoin-only exchanges 2 Lightning-enabled wallets 2 on-chain wallets 2 BTC-backed lending services, with another on the way 2 collaborative security services 1 Bitcoin hardware device The world’s leading on-chain analyst Countless self-custody & cybersecurity mentors A Bitcoin-only industry body Numerous Bitcoin-only online shops World-renowned graphic & UX designers World-renowned developers & cryptographers The home and birthplace of the Bitcoin Bush Bash Bitcoin Alive conference Countless mining services (including a Bitcoin-powered beer brewery) Countless node runners At least 8 Bitcoin-only podcasts And I’m sure I’ve missed plenty. What else should be on the list? 👇
