Live at PubKey NYC

Welcome back to Coin Based, our live Bitcoin discussion series! Live from PubKey NYC, ArbedOut is playing host this week, with Marty Bent (Founder, TFTC) in the room and Rob Hamilton (CEO, AnchorWatch) beaming in.

Two months after Coldcard, there's another hardware wallet hack to unpack: the Ledger reseller attack. They cover how tampered Ledgers with a SIM card and modem inside got into the supply chain, the $101 million drained from 342 wallets, how Coldcard and Ledger botched their crisis response, and whether Bitcoin needs an Apple to build hardware wallets.

0:00 INTRO: Welcome back to Coin Based!
2:16 How the Ledger hack unfolded: a reseller sold to China, and Mark Karpelès takes one apart
7:32 $101 million stolen from 342 wallets
11:54 What could victims have done differently?
14:11 Why no multisig wallet got drained (and what if all your Ledgers were tampered?)
16:19 Would covenants have stopped this? (letting your wallet refuse unknown addresses)
21:12 Security has to be on by default (the WhatsApp encryption problem)
27:21 How much Bitcoin before you need multisig? Rob's rule of thumb
28:39 Supply-chain risk: who do you trust before Ledger? Foxconn, chip makers and the Bitmain backdoor
32:34 Does open-source hardware fix this?
38:15 Should you build your own wallet? SeedSigner and air-gapped laptops
44:50 Grading Coldcard and Ledger's crisis response
50:43 Does Bitcoin need an Apple to build hardware wallets?
56:19 The Mark Karpelès redemption arc, and how far attackers have come since Mt. Gox
1:04:05 Should you auto-update everything now that AI is hunting bugs?
1:12:35 CONCLUSION: Pandora's box is open.

STREAMING LIVE AT PUBKEY NYC! Tonight, the Human Rights Foundation and PubKey dive into how Freedom Tech and Bitcoin advance humanitarian goals.

In this fireside chat, lead developer of the SeedSigner project Keith Mukai will share the best security practices in self-custodying with hardware devices, the security advantages a DIY hardware wallet with store bought parts can provide, and how human rights defenders who need secure self custody the most can benefit from employing these practices.

The Coin Based boys are back for another emergency broadcast—this time, officially brought to you by Anchorwatch.

Host Thomas Pacchia sits down with arbedout, Alex Thorn, and Rob Hamilton to make sense of current Bitcoin discourse. They cover how much was really stolen from Coldcard and who's still at risk, how a bug let someone mint bitcoin out of thin air on Liquid, whether the person draining it is a "white hat" or an extortionist, and why the CLARITY Act died at the last minute in Washington.

0:00 INTRO: An emergency broadcast on Coldcard, Liquid & Clarity
2:11 Coldcard update: 1,807 bitcoin gone, and the victims left behind
9:29 Is any single hardware wallet safe now?
13:33 Did Coinkite's arrogance make it worse?
17:13 How the attacker actually cracked the wallets
24:52 Could the same bug hit other wallets? (and the Bitfinex parallel)
28:07 Is this the end of the toxic Bitcoin maximalist era?
35:33 Is open source making Bitcoin an easier target?
44:23 How AI supercharged the Red Team's bug hunting
48:22 The Liquid hack: how someone minted bitcoin from thin air
53:22 Who pays for the Liquid hack — and can you prove the coins were yours?
56:22 Is the Liquid hacker a "white hat" or an extortionist?
1:13:06 Why people are furious at Blockstream's response
1:19:17 Should frontier AI models be restricted?
1:22:01 Is Bitcoin's core crypto library secretly backdoored?
1:26:48 What killed the CLARITY Act?
1:36:13 "We pay for this": Thomas on Washington dysfunction
1:39:45 What the BRCA was actually trying to protect
1:44:32 Is quantum computing a real threat to Bitcoin?
1:51:06 How crypto out-lobbied the banks
1:53:44 CONCLUSION: a brutal week, and what comes next

COIN BASED is back at PubKey NYC. This time, we're digging into the Noah Doe lawsuit and how two parties are coming for the same dormant Bitcoin from opposite directions. Best part is, neither one has the keys. 3.8 million dormant BTC are at stake.

Everyone is discoverable.

But how does someone actually go from knowing your handle to knowing your address? Between data brokers, leaky apps, and a decade plus of KYC, the line between "online footprint" and "someone showing up at your door" is thinner than most people realize.

Join Rob Wallace (Bitcoin News) and Alec Harris (CEO havenX) for a real conversation about how Bitcoiners (and honestly, everyone) are getting tracked and targeted... plus the perimeters, digital and physical, that hold up in practice.

What was it like resisting Daniel Ortega's bloody dictatorship?

We're streaming LIVE AT PUBKEY NYC right now with Félix Maradiaga (President of the World Liberty Congress) and Jhanisse Vaca Daza (HRF's Freedom Fellowship Director) to explore Maradiaga's experience resisting Ortega, leading WLC, and how political dissidents and human rights activists around the world use Bitcoin and other freedom tech tools to defend their freedom.

The Coin Based boys (ArbedOut, Drew Armstrong) are back with the fine folks at Blockspace Media (Charlie Spears, Will Foxley) to help congratulate them on an excellent OP_NEXT 2026. Tune in and eavesdrop on all the things we couldn't say during the conference:

• What our most (and least) favorite panelists were
• The definitive take on whether Bitcoin mining is the stupidest business model in existence
• The definitive take on Bitcoin quantum risk that even the X ragebaiters aren't ready to hear
• ...and more!

Legendary Bitcoin developer Calle (Cashu, Clawi) and host Alex Li (Bitcoin Development Lead at HRF) take the stage in their LIVE AT PUBKEY show at PubKey NYC to discuss the future of open-source freedom tech. Plus:

• Calle's exact agentic coding stack to boost his productivity by 100x (no, actually)
• Calle's unique perspective on the Bitcoin quantum debate as an actual physics PhD
• How Calle knew he'd found his lifelong passion in developing freedom tech (and how you can find your life's goal, too)
