A threat model is not a fear list. It's one page: the secrets you protect (not the apps), the realistic adversaries, the one or two outcomes that would actually ruin you, and the costs you accept. Its real job is telling you what you can safely ignore. It now opens the Keys module of Sovereign Starter.

Local AI on a PS5 A jailbroken PlayStation 5 is now running llama.cpp as a native app that uses the GPU. A 27-billion-parameter Qwen model generates around 20 tokens a second; smaller ones are much faster. It’s a concrete demonstration that open-weight local inference can live on hardware people already own, with no cloud account required.

Monero FCMP++ Monero’s next privacy step is still moving. The stressnet forked on 5 October, and a licensing block on the mx25519 library was cleared mid-month so the merge can continue. Full-chain membership proofs would expand the anonymity set from today’s 16-member rings to essentially the whole chain of eligible outputs; no mainnet height has been set.

LayerTree Lightning Labs published a design that lets thousands or millions of people share one Bitcoin output. Balances sit in an off-chain Merkle-sum tree; covenants keep the operator from taking funds, and any member can still leave alone in a single transaction whose size doesn’t grow with the group. It needs opcodes that have been proposed but aren’t active yet, so it’s research with a reference implementation rather than something you can run today.

Monero FCMP++ stressnet Monero’s third beta stressnet for Full-Chain Membership Proofs (FCMP++) and the CARROT addressing changes has been running, aimed at moving the anonymity set from today’s fixed ring of 16 up to essentially the whole chain history. No mainnet date is set; it is still testing and audit work. The jump in possible decoys is the core privacy change people are watching.

Meta’s Muse Spark Open Meta released the weights for Muse Spark Open, an 816-billion-parameter model (42 billion active) with a million-token context that is built for coding and longer agent tasks and can run on two Apple M5 Ultra Mac Studios. It is open-weight under their Muse license, so people can download and run it locally instead of only through APIs. Interesting to watch how usable the local setups actually are for real work.

LayerTree proposal Lightning Labs put out a design where one Bitcoin output can hold balances for up to a million people, tracked off-chain in a Merkle-sum tree, with covenants so anyone can leave in a single transaction without timeouts or needing to stay online. It still needs opcodes that aren’t activated yet, so it’s a paper and reference code rather than something you can use today. Curious what the trade-offs look like once those opcodes land.

Sovereign Starter got a rebuild: 5 modules, 10 beginner steps, a quick check after each. 1. Keys – verify, then sign offline 2. Money – receive-only Lightning, default-private money 3. Nostr – relay lists and what they get wrong 4. Storage – encryption and immutable chunks 5. Local AI – where your data actually lives No account, no cookies, no tracking. Four new notes land next week to fill the gaps.

Running an agent in Docker is the starting line, not the boundary. With Agent Zero, what actually decides what it can reach is the bridges you enable: - where each model slot sends data (chat, utility, embedding, browser, vision) - host file read/write (F3) and code execution (F4) - Docker browser vs your own browser, and whose cookies - every plugin and MCP server List those and you've got your real boundary.

Monero’s FCMP++ privacy upgrade continues through stressnet testing that forked earlier this month, with developers reviewing code that supports the move to far larger anonymity sets than current rings. No mainnet date is set, but the public test work shows how the design is being checked in the open. More plain notes on these tools at cryptodecentral.co.za

Your AI agent can read CryptoDecentral directly. The Sovereign MCP server serves our source-checked notes, directory and guides as tools. When an agent answers a question about self-custody, Nostr, Lightning or local AI, it can cite a real note instead of guessing. It's listed on the official MCP Registry, and the setup is here:

"I already have this model" is not a verification step. Ollama 0.40.2 started converting models you'd already pulled into llama.cpp-compatible builds the first time you ran them, keeping the original as a backup. Same tag, new files on disk, more space used. 0.40.3 then paused it. Check what changed on disk, not just the name in `ollama list`.

Every listing in the CryptoDecentral directory was re-checked at its source today: live sites, current repos, real licences. New: four self-custody Monero wallets — Monero GUI & CLI, Feather, Cake Wallet and Stack Wallet. Each with a plain caution note (built-in swaps are third-party; we don't endorse them). Nothing here is ranked or paid to be listed. Sponsored spots are always labelled.

Your seed phrase backs up keys, not your wallet. 12 or 24 words don't say which scripts those keys wrap, which paths hold receive vs change, or who your multisig cosigners are. Restore in a different app and "I have the words" can become "I can't see the coins." BIP 380 output descriptors are the missing piece: one checksummed string naming script type, key origins and ranges. Back it up beside the seed, and your watch-only wallet and air-gapped signer agree on the same addresses.

An anonymity set is not a ring size. Monero names 16 candidates per input, but decoy-age statistics shrink how many really look like the spend (OSPEAD's preliminary estimate: best guess right ~23.5% vs 6.25% random). Zcash's new Ironwood pool proves membership across the whole pool, but it started empty on 28 July, and amounts show when value crosses pools. FCMP++ aims at the whole chain. Still on beta stressnet. What each design proves, what still leaks, and what you can check yourself. No winner picked:

An Anonymity Set Is Not a Ring Size

An anonymity set is the group of candidates an observer cannot tell apart, not the count of candidates a transaction names.
