Ready to start a new project

1/12🧵 A ~$89M Coldcard hack was, per Coinkite, likely found by AI reading the open-source firmware, while the vendor's own AI audit weeks earlier missed it. So we built OpenSourceCheck: a public, cryptographically-signed registry of AI security audits of Bitcoin open source. It records what was checked, by which model, and what came back, and never claims code is "safe." 3 real audits live, all verifiable offline. How it works 👇

I wasn't affected. Not because I was smart. By pure chance. That's the only thing separating me from the people who lost everything this week. My mind is with all of them. People who did the right thing, took self-custody seriously, followed the guidance, and got wiped out anyway. This is fucking devastating. Coinkite is probably done, and honestly they should get all the blame for it. Five years of broken entropy is not a small mistake. If they want to pay something back, and nothing pays this back, they should MIT license the whole product and hand it to the community. It doesn't fix what was done. It's just the least they owe us.

Brick by Brick... The Bricks & Minifigs drama is secretly a Bitcoin lesson in a little LEGO hat. 🧱 Speedrun: family consigns a ~$200k collection. Store sells it, money's meant to flow back, franchise changes hands, new owners go "what bricks? 👀" and corporate goes "wasn't us, good luck!" Fair, someone will yell: "Bitcoin can't teleport plastic spaceships back to Oregon!" Correct. Custody of physical stuff is hard and no money fixes that. But this was never a LEGO problem. It was a money-flow problem in a LEGO costume. The seller never touched the payments. Every sale dumped cash into the middleman's pot, and you just had to pray whoever held it felt like sharing. They didn't. 🫠 Here's Bitcoin's flex: payment settles straight to the seller, instantly, with no mythical "we'll distribute it later." Multisig escrow means nobody walks off with the bag, because the bag needs more than one key to open. And when a new owner takes over? The keys to the sats were never theirs, so "the old guy kept your money" stops being a sentence that can exist. You can't always stop them sitting on your bricks. You CAN stop them sitting on your money, and here the money was the whole heist. The plastic was just the alibi. Brick by Brick, Sat by Sat. 🧱⚡

Hashden, the non-custodial marketplace of Bitcoin solo-mining dens Open alpha update. What works today: - Multi-tenant stratum + multi-output coinbase (PPLNS / solo / operator fee / dust). 200 fuzz cases, validated on a real Bitaxe. - Block reward → coinbase pays every member on-chain → Lightning fan-out for sub-dust → a NIP-57 zap receipt per payout. No platform balance, ever. Operators can't quietly skim. - Anonymous by default: no IP logs, npubs hidden unless you opt in per den, payout addresses redacted until a block actually lands. - Don't trust us, verify: a coinbase-verifier CLI you run on your own hardware confirms every job pays YOU before you hash. Every image is cosign-signed + SLSA-attested, prove hashden.app runs the public repo at /verify. Your Nostr key is your identity. No email, no KYC. GPL-3.0, all of it. Find a den, point your Bitaxe, chase blocks together →

Is there any decent BIP about making Bitcoin more private?

⛏️ Hashden A marketplace of Bitcoin solo-mining dens. A den is a self-run mini-pool. Open one with your Nostr key, set a fee, share the link. Miners join by pointing their Bitaxe at it. Find a block → the coinbase pays every member directly, weighted by shares. Non-custodial: the platform never touches your sats. Every payout posts a NIP-57 receipt, so nobody can skim quietly. Anonymous by default. No IP logs, no KYC, your npub stays hidden unless you opt in. Open alpha →

Hashden: a marketplace of Bitcoin solo-mining dens. ⚒️ Join a den, point your Bitaxe (or rented hashpower) at it, and if the den hits a block the reward goes straight to miners through the coinbase, no pool wallet, no IOUs, no "we'll settle later." Non-custodial by design. Nostr login, no email/KYC. Sub-dust shares get fanned out over Lightning. Open alpha →

Ross should now build the biggest ecommerce website(Amazon like) based on bitcoin payment system! I would buy there!

Is there any slack like client for nostr?
