I've just released a major rewrite of my offline BIP39 seed generator. The project now includes: • mandatory OS CSPRNG • optional supplemental entropy (manual input, dice, timer jitter) • HKDF-SHA512 mixing • BIP39 validation • self-test • automated tests • Windows/Linux support The goal wasn't to reinvent seed generation, but to build a transparent, offline, open-source implementation that's easy to inspect and improve. Feedback and code review are always welcome.

GitHub - shadowbipnode/Seed-Phrase-Generator-with-Multi-Source-Entropy: The script combines these data sources to ensure a highly random and secure seed phrase generation. It also generates a QR code of the seed phrase and saves all related files (audio, video, QR code) for verification purposes.

your logs show brute force attempts on your node way before you notice. install fail2ban to jail those ips automatically. it is simple defense that keeps your node resources for legitimate traffic instead of wasting them on attackers.

lnbits is not a set-and-forget wallet. thinking you can install every extension without isolating them is how a single rogue plugin takes down your entire node database. isolate your instances. thread.

if you run lightning nodes on tor, check your logs for 'clock drift'. if your system time is off by even a few seconds, onion connections will refuse to handshake. verify with ntpq -p before assuming the peer is dead.

stop trusting your lnd backup script if you haven't actually triggered a restore. an untested channel.backup is just a text file. move your node to a testnet machine and see if it syncs. do you know how to rebuild your state yet?

Bitcoin is not anonymous. It's pseudonymous. And in 2026, breaking that pseudonymity is a multi-billion dollar business. Chainalysis, Elliptic, CipherTrace — they map your addresses to your real identity. Governments pay hundreds of millions for this. The good news: there's a full privacy stack that makes surveillance prohibitively expensive. CoinJoin → PayJoin → Silent Payments → Lightning → Tor → your own node. Complete guide (free): 👉

stop relying on the auto-generated backup file alone. if your disk dies and you can't map your channel state to an on-chain commit, you are toast. when was the last time you actually dry-ran a recovery?
