Featured pillars
Privacy, DeAI, Nostr, wallets
Sharp field guides — not a trading terminal.
Privacy money
Monero-class privacy: threat models, how the tech works, and why opaque ledgers matter.
Decentralized AI
Open weights, local inference, and decentralized compute — tech, not tokens-to-buy.
Nostr
Keys as identity, public relays, clients, and zaps — without running a relay product.
Self-custody & wallets
Seed hygiene, hardware overview, and the habits that keep keys yours alone.
