Open Accounting
Finance is part of building in public, the same way engineering is. A Bitcoin wallet on OrangeCat is non-custodial — the platform watches an address or an extended public key and never holds a key. This project makes such a wallet able to account for itself in public, for owners who choose it: what it holds, what moved, and the owner's own explanation of each transaction. Open accounting is opt-in per wallet, because a wallet is labelled by need and publishing that is the owner's decision, not a side effect of a feature. On top of it goes a transparency score computed from what the platform can observe — whether a wallet publishes its ledger, how much of it is explained — never from claims. An earlier score existed and was deleted in May 2026 because it scored booleans the caller passed in; that is the mistake being corrected.

substrata
Open research on the physical bottlenecks of technological progress: materials, compute, energy, science, policy, capital and talent, with checkable evidence and public contributions. Beta — running, not released. Vision: A collaborative research service where anyone can follow a technology chain, inspect the evidence behind a claim, personalise their learning and contribute expertise that improves a shared public map.
