A protocol for issuing and exchanging claims against publicly defined promises. The goal is open entry, private payments and independently verifiable supply. Holders choose which promises to accept; the protocol does not guarantee repayment.
The project brings together an argument for the design, a normative specification and an experimental implementation.

The reference implements private notes, public supply replay, canonical history, receipt readers and durable sequencing. Runtime recovery, a pool wallet and external witness publication are still in development. There is no published npm release or completed security audit; API and wire formats can change.
See the implementation status for evidence and limits, and the decision index for design rationale.
