# BitBlocks — TODO The umbrella site + narrative for the stack (BitLogin · BitGate · BitFeed · BitUnlock, and Tessera as the worked example). ## Design review — external critique (2026-08-11) An outside review of the whole stack (concept rated ~9/10). The concept is strong; the actionable notes are precision and positioning, which matter a lot for security infrastructure. Distilled, with our take: ### Positioning - **[agree] Stop calling all five things "primitives."** Tessera is an application built WITH the stack, not a fifth primitive. Reframe as **"Four primitives. One proof they compose."** — a PRIMITIVES tier (BitLogin · BitGate · BitFeed · BitUnlock) and a BUILT-WITH tier (Tessera, then future apps). A stronger story than forced five-way symmetry. - **[agree] Add one architecture diagram:** Nostr / Lightning → the four blocks → Tessera / future apps. Communicates the whole project in ~ten seconds. - **[agree] Sharpen the thesis:** "BitBlocks is an application architecture in which identity, policy, discovery, payments, and capabilities are portable objects rather than proprietary backend services — the client becomes the disposable part." Keep the hero line ("The web made you a tenant. Own the stack."). ### Claim precision (highest priority — this is security infra) - **[strongly agree] "No server of record" overclaims.** BitUnlock is a hosted service with a D1 database. Reframe the principle to **"No platform-owned source of truth"** / "Portable state first, replaceable services where services are necessary." Servers are allowed; a server OWNING the user is not. - **[strongly agree] Drop impossibility claims** like "no one can delete your history." Relay retention is best-effort (BitLogin's own docs say so). Use "no single operator controls…", "portable across…", "doesn't depend on one host…". Audit every absolute claim on the umbrella page AND each block site. ### Strategy - **[agree] Resist over-expansion.** We have enough primitives. The validation goal is NOT a fifth infrastructure layer — it's a SECOND, radically different application on the same four blocks with no special-casing. Two unlike apps composing cleanly from the four primitives proves an *architecture*, not a product family. That's the north star; let real application pressure decide what the stack is missing.
