FCMP++ Proof Transcript
| Proof Type | FCMP++ Full-Chain Membership Proof |
| Anonymity Set | Entire Chain (all outputs ever created) |
| Inputs | 2 |
| Proof Size | 6,080 bytes |
| Curve Tree | Helios (C2) dual-curve architecture |
| Tree Layers | 4 |
| Tree Root | 3f6ce78de4cc68394b728b732cda89cf16ba57ba616027bc334363107e753a1c |
Curve Tree Structure
Layer 0 (Leaves) : Ed25519 output tuples (O, I, C) → Selene (C1) hashes Layer 1 (Interior) : Selene (C1) → Helios (C2) commitments Layer 2 (Interior) : Helios (C2) → Selene (C1) commitments Layer 4 (Root) : Helios (C2) tree root
The full output set is committed into a Helios/Selene curve tree. Each leaf encodes an output tuple (O, I, C) as Selene curve points. Interior nodes alternate between Helios and Selene curves, enabling efficient recursive proof composition.

Nullifier: The key image
KI = x · Hp(O) is a deterministic, unlinkable nullifier. It prevents double-spending without revealing which output is being spent.

Nullifier: The key image
KI = x · Hp(O) is a deterministic, unlinkable nullifier. It prevents double-spending without revealing which output is being spent.
Spend-Auth & Linkability (SAL) Proof
ÕRerandomized one-time key
ĨRerandomized linking tag
RRerandomization scalar
C̃Rerandomized Pedersen commitment
The SAL proof demonstrates knowledge of the secret spend key, correct key image formation, and that the balance equation holds: Σ pseudo-outs = Σ output commitments + fee.
