Your Bitcoin Privacy
Is Under Attack

About Nodl

Nodl's founder is Michel Luczak, known online as Keto Miner, a French builder with an electronics background who discovered Bitcoin around 2010-2011 and got deeply involved through Paris Bitcoin meetups in 2017. He built his first Bitcoin full node that year on a Raspberry Pi Zero stuffed into an external hard drive case, doing initial block download in about a week, and turned that DIY experiment into a company.

Nodl sells a plug-and-play node box that ships ready to run Bitcoin Core, Electrs, Lightning, BTCPay Server and Whirlpool mixing out of the box, with full-disc encryption, Tor-only networking by default, and a physical kill switch that wipes hot-wallet memory if the case is opened. Unlike DIY builds on a Raspberry Pi or old laptop, it is sold with a 5-year warranty and a paired cloud offering for nomads and online merchants who cannot or should not expose a home IP address when accepting Bitcoin.

This conversation is worth watching because Michel is refreshingly blunt about the real threat model: he explains exactly what a Tor-only node hides from your ISP, why running BTCPay from home leaks your physical location, where Lightning privacy actually breaks, and why he still uses a custodial Wallet of Satoshi for conference spending. He also announces Nodl's new Onyx model live on the show, with concrete specs and a 30x IBD speedup over the 7-year-old platform it replaces.

What was said

1. 07:00 Michel says the best way to acquire Bitcoin is to mine it, second best is to earn it, and buying on an exchange is a distant third, because mined and earned sats are non-KYC by default.
2. 11:00 Origin story of Nodl: a 2017 Raspberry Pi Zero with 512 MB RAM and a small SSD crammed into an external hard-drive case, syncing the chain in about a week, built to run bitcoin-cli without using his main computer.
3. 20:00 Running BTCPay Server from home over an open router port leaks your public IP to every customer who pays you, and ISP triangulation can pin that IP to a physical address, which is why half of Nodl's cloud users are online merchants.
4. 23:00 The node requires a 32-character password on boot and ships with a physical kill switch: opening the case cuts power and wipes the hot Lightning wallet (some users hold up to 10 BTC on it) from memory, partly inspired by cold-boot memory attacks NVK flagged.
5. 27:00 Announces the new Nodl Onyx Founders Edition live on the show: 32 GB RAM (vs 4 GB on the current model), 4 TB redundant storage, Tor-only by default, and roughly 30-40x faster initial block download than the 7-year-old platform it replaces.
6. 36:00 Pushes back on 'the internet is centralized because sites run on Amazon': the internet is actually tens of thousands of independent ISPs anyone can join, and Bitcoiners should understand that underlying layer before arguing about Bitcoin itself.
7. 39:00 Brutally honest on Lightning privacy: receiver privacy is poor because you leak node info in every invoice, routing is still a nightmare with frequent timeouts, and he personally uses a custodial Wallet of Satoshi when spending at conferences.
8. 45:00 Biggest everyday privacy mistake he sees is aging Bitcoiners posting their kids' faces on Instagram: AI aging tools plus existing photo databases make that OPSEC failure worse than almost anything on-chain.
9. 51:00 Long-term vision: turn Nodl Cloud into the AWS of Bitcoin companies, with 10-20 data centers across jurisdictions so a user can run their node replicated across multiple legal zones and kill any leg that becomes too exposed.
