BCH Confidential Protocol Documentation

This site documents a protocol-first approach to direct-spend confidential transactions on Bitcoin Cash (BCH) Layer 1.

The protocol defines confidential state transitions and verifier boundaries. The runtime and wallet sections describe reference implementations of that protocol boundary; they are not the protocol definition itself.

Current Publication Boundary

• Current truth: first-hop and follow-on direct spend are live-validated for the current bounded lane.
• Proof-enforced semantics: bounded two-input confidential accounting semantics are enforced in the published lane.
• Artifact-described behavior: wallet artifacts describe additional behavior that is not automatically proof-enforced.
• Public observables: BCH graph, shell economics, and fee surfaces remain public on direct-spend Layer 1.
• Future optional aggregation: observability reduction is deferred to later optional aggregation work.
