SEPTEMBER 10, 2026 A Jar Is Not a Vault: Reading My Friend's Lightning Wallet Before I Recommend It A friend of mine spent six months building a self-custodial Lightning wallet that runs in a browser, and he'd be the first to tell you it has no audit. I trust him — which is exactly why I shouldn't ask you to trust it on my say-so. So I read the code, checked the served binary against the published hashes, and worked out what the trust model really is. Along the way, the thing every Lightning wallet review should say and mostly doesn't: what a Lightning wallet is for, and what it is not. SEPTEMBER 10, 2026 Six Million Tokens in Eleven Minutes Some friends and I have been arguing about whether it will ever seem normal to spend six million tokens in eleven minutes to make a blog post — and whether a world where the well-off can run AI flat out leaves everyone else with the crumbs. So I priced the tokens, traced where the price is going, and went back to the last time a machine cost more than a house. The number that matters isn't the token count. It's which of two prices you're paying, and who is paying for the free one. SEPTEMBER 9, 2026 "Not Your Keys, Not Your Coins" Just Grew a Second Half Alby disclosed a critical flaw in Alby Hub, its self-hosted Lightning node software, that could let an attacker who reaches an exposed control panel send your bitcoin out from under you. The twist worth sitting with is the timeline — the fix shipped over a year before the warning did — and what that gap actually tells self-custody Bitcoiners about the setting they should have checked already. SEPTEMBER 9, 2026 "Coded and Audited by AI," and the Longer Story Underneath That Sentence A beta Bitcoin wallet's own README says, in one sentence, that it was coded and audited by frontier AI models. Taken alone that sentence would worry me. Taken alongside the actual security document and the actual changelog, it turns out to be shorthand for something more specific, more human, and more interesting than the sentence lets on.
