That piece made a claim: that a platform can be private and safe at once, and that the same cryptography which protects you also protects the commons. This piece is the receipts — how the safety layer actually works, published on purpose so you can check it, and break it. A good security system doesn't depend on its design being secret. If the only thing protecting you is that the attacker doesn't know how the lock works, you don't have a lock. So here's exactly how ours works. ## Why this exists at all Before the mechanism, the reason for it. Open Forum rests on a single founding idea — a definition of freedom stripped to its core: **no person may reduce another's ability to choose.** We call it the Rule of Freedom, and everything else derives from it. That one sentence is why this safety layer had to exist, and why it had to be *this* hard. The axiom protects you — no one, not even us, may reduce your ability to speak or choose. But it equally condemns harm, because harm is simply one person reducing another's ability to choose: a child in an abuse image, someone whose private life is taken and broadcast. Those aren't exceptions to freedom we reluctantly police — they are freedom being violated. Stopping them isn't a limit on freedom; it's freedom's enforcement. And here's the trap the axiom sets. The lazy way to stop harm is surveillance — watch everyone. But surveillance *also* violates the axiom: it reduces the watched person's freedom. So we couldn't take the easy path. We had to catch genuine harm without surveilling anyone, and prove we weren't quietly doing it anyway. There's no off-the-shelf tool for that — which is what pushed us to build what you're about to read, and, as far as we know, to a standard no other sharing platform has reached. We say that with pride, and with an open challenge: if someone has done this better, show us. We want to learn it. ## The problem, stated honestly Some content is illegal to possess, full stop — child sexual abuse material being the clearest case. That creates a genuinely hard problem for any host, and an especially hard one for a privacy-first, self-hosted platform: - We can't just ignore it — hosting it is a crime, and there's a legal duty to detect, preserve, and report. - We can't delete it on sight — destroying it can itself be an offense, and it's evidence. - We can't *look* at it to make decisions — viewing it is the crime we're trying to prevent, and no operator or community member should ever be put in that position. So we need to catch it, keep it, and hand it to lawful authorities — while **no human on our side ever sees it**, including us. That's the needle to thread. ## Detection: fingerprints, not eyes Detection is done by matching content against a database of *fingerprints* of known illegal material, maintained by a child-protection organization. It's a mathematical comparison — a hash — not a system that "looks at" or "understands" your images. Crucially, the check runs so that the actual image data never leaves your node to make the decision. We're deliberately not publishing the specifics of coverage — where the checks sit, the thresholds, the gaps. Not because the mechanism is secret (it isn't), but because a detailed map of *what slips through* is an instruction manual for the exact people we're trying to stop. That's the one place "publish everything" would help predators and no one else. What we will say plainly: it catches *known* material. It is a floor, not a magic wand. ## The sealed box: caught, kept, unreadable — even by us When something is flagged, this is where the real design lives. In the same instant it's detected: 1. **It never goes public.** It's refused — never stored in the shared space, never sent to other nodes. 2. **It's encrypted immediately, in memory,** and only the encrypted form is written to disk. The original is never saved anywhere readable. 3. **It's locked to hardware, twice.** Opening the box requires *both* a security chip on the machine *and* a physical hardware key held by the operator. Not a password — physical objects. 4. **And here's the part that matters most:** the security chip is wired so that it physically *cannot* release the key without permanently ticking a hardware counter forward. That counter can never be wound back — not by us, not by anyone with full control of the machine. Put those together and you get a guarantee that isn't a promise, it's math: **as long as that counter reads zero, the box has provably never been opened.** We can show that the material was caught, sealed, preserved for authorities — and *never seen by a single human*, ourselves included. This isn't us asking you to take our word that we didn't look. *We couldn't have — and here is the proof.* Every action — sealing, and any future court-authorized opening — is written to a tamper-evident log that's anchored into that same hardware, so the record of custody can't be quietly rewritten either. ## When the law needs it If authorities come with a warrant, there's a defined path to retrieve the sealed material for them — which advances that counter, on the record, witnessed. The design goal is that lawful access is possible and fully accountable, while casual or secret access by *anyone* — operator, attacker, insider — is impossible, not merely forbidden. ## The road from here What exists today is the floor. Here's where the standard is going — published on purpose, so you can hold us to it: - **Public verifiability.** Today, the "never opened" counter is something *we* can show you. Next, that count gets signed by the security chip itself and anchored on our own public ledger — so *anyone* can verify the box was never opened, without taking our word for a single thing. - **Two-key lawful access.** The path for a warrant will require *two* independent parties — a police representative and a judicial one — both needed to unseal, tied to a real legal order, fully logged. No single official, and no operator, can ever open it alone. - **A rising, community-owned standard.** The safety floor shouldn't be set by us forever. Over time, the community raises it through the platform's own governance. - **A standard others can adopt.** We want this to become a certification *other* platforms can subscribe to and be measured against — so the bar rises past us, not just with us. - **Run it yourself.** Every piece is meant to be self-hostable, with no third party anywhere in the chain of trust. None of this is "someday" hand-waving. It's the committed direction — and publishing it is how you get to hold us to it. ## The honest limits — and the invitation We'll tell you what this isn't, because overclaiming is how safety promises turn into lies: - It catches **known** material by fingerprint. Novel material isn't magically recognized. - It is a **floor** — the minimum a node should be able to prove — not a ceiling. The standard is meant to rise, in the open. - We got things *wrong* on the way here and corrected them. Our first instinct was to let the operator hold a key that could open the box — until we realized that just rebuilds the "trust me" problem we were trying to delete, so we removed our own ability to look. The proof matters more than the promise, and the proof only counts if you can inspect it. Which is why this is published. If you can find a way to fool the detection, break the seal, forge the log, or open the box without moving the counter — **tell us.** You won't be treated as an attacker. You'll be treated as what you are: someone helping build the immune system, in public, where it belongs. *Built on Open Systems.* ``` ## Replies, oldest first (member-written text) none yet
