A Model Tag Is Not a Runner Contract: Ollama’s MLX Default and What Still Differs
Ollama v0.40.0-rc0 defaults supported Apple Silicon models to MLX under the same pull/run tags — a model tag is not a runner contract. Pin versions, name the engine, keep offline plans honest.
A Subaddress Is Not a Separate Identity: Janus Outputs, Sweeps, and the Seed Boundary
Subaddresses give you receive unlinkability against observers and honest payers. They do not give you identity isolation against an active counterparty, your own consolidation transactions, or a service's account database.
Docker Is the Starting Line, Not the Boundary: Mapping Every Bridge Out of Agent Zero
Agent Zero's container is the default starting position, not the security boundary. The real boundary is the sum of the bridges you enable: which model endpoints each slot talks to, whether the host connector may read files or run code, which browser it drives, and which plugins, MCP servers, and extensions you install.

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.

An Allow-List Is Not an Admin List: What Agent Zero 2.15 Fixed in Its Chat Channels
Agent Zero 2.15 stops chat users from lifting their own tool limits. Why being allowed to message an agent must not mean being allowed to change its rules.

An xpub Is Not a Public Key: What Sharing an Extended Public Key Actually Exposes
An extended public key is a public key plus a chain code. Shared, it reveals every past and future address in its subtree, and with one leaked child private key it gives up the parent private key. BIP 32 says so directly.

A Deletion Request Is Not Erasure: What Nostr Kind 5, Kind 62 and Expiration Actually Do
On Nostr, deletion is a signed request addressed to relays and clients, not an operation on the network. Kind 5 asks, kind 62 binds supporters, and expiration is a hint — none of them erases every copy.
