chore: remove build artifacts and update .gitignore
Remove temporary build error logs and binary artifacts: - build_err.txt - build_error_j1.txt - capsule-core/build_errors.txt - root (binary data file) Add patterns to .gitignore to prevent future commits of: - build_err* and build_errors.txt - 'root' artifact files

# RFC-0315 Access Toll Protocol - Winterfell Edition
|
||||
|
||||
**Status:** WINTERFELL INTEGRATION v0.2.0
|
||||
**Target:** Zig 0.13+ + Winterfell (Rust STARK library)
|
||||
**License:** EUPL-1.2
|
||||
|
||||
## Strategic Decision: Winterfell over Cairo
|
||||
|
||||
| Dimension | Winterfell | Cairo VM |
|
||||
|-----------|------------|----------|
|
||||
| **Modularity** | ✅ Clean prover/verifier separation | ❌ Monolithic VM |
|
||||
| **Integration** | ✅ C FFI → easy Zig bindings | ❌ VM embedding complexity |
|
||||
| **Stack Size** | ✅ ~5KB recursive proofs | ❌ Larger proof overhead |
|
||||
| **Libertaria Fit** | ✅ Matches minimal philosophy | ❌ Overkill for our needs |
|
||||
| **Compile Time** | ✅ Fast Rust compilation | ❌ Slow VM initialization |
|
||||
|
||||
**Winner:** Winterfell for clean, modular STARK integration into Membrane.
|
||||
|
||||

## Core Components

|

### 1. Hamiltonian Toll Controller (`HamiltonianToll`)
|
||||
|
||||
Integrates RFC-0648 velocity-based pricing:
|
||||
|
||||
```zig
|
||||
var ham = HamiltonianToll{
|
||||
.pid = PidController.init(0.5, 0.1, 0.05),
|
||||
.base_toll = 250,
|
||||
.v_target = 1.0,
|
||||
};
|
||||
|
||||
const band = ham.calculate(v_measured, dt);
|
||||
// V < target → reduced toll (stimulus)
|
||||
// V > target → increased toll (cooling)
|
||||
```
|
||||
|
||||
### 2. Winterfell STARK Circuit (`TollAir`)
|
||||
|
||||
AIR (Algebraic Intermediate Representation) for toll clearance:
|
||||
|
||||
```zig
|
||||
const TollAir = extern struct {
|
||||
trace_width: u32, // 5 columns
|
||||
trace_length: u32, // 64 rows (power of 2)
|
||||
constraint_degrees: ..., // Quadratic constraints
|
||||
public_inputs: ..., // commitment_hash, nullifier
|
||||
assertions: ..., // Boundary constraints
|
||||
};
|
||||
```
|
||||
|
||||
**Trace Layout:**
|
||||
| Column | Purpose |
|
||||
|--------|---------|
|
||||
| 0 | Resource ID hash (Blake3 intermediate) |
|
||||
| 1 | Amount (decomposed for range check) |
|
||||
| 2 | Nonce |
|
||||
| 3 | Commitment computation trace |
|
||||
| 4 | Nullifier derivation |
|
||||
|
||||
### 3. Proof Generation (`generateTollProof`)
|
||||
|
||||
```zig
|
||||
const proof = try generateTollProof(
|
||||
allocator,
|
||||
resource_id,
|
||||
amount,
|
||||
nonce,
|
||||
secret_key,
|
||||
toll_band,
|
||||
);
|
||||
|
||||
// Returns TollClearanceProof with:
|
||||
// - stark_proof: Winterfell STARK
|
||||
// - serialized: Bytes for transmission
|
||||
// - commitment_hash, nullifier: Public inputs
|
||||
```
|
||||
|
||||
### 4. Kenya-Optimized Verification
|
||||
|
||||
**Immediate Mode** (high-resource routers):
|
||||
- Full Winterfell verification
|
||||
- ~10-50ms verification time
|
||||
|
||||
**Lazy Mode** (Kenya/low-resource):
|
||||
- Optimistic acceptance
|
||||
- Batch verification (100 proofs)
|
||||
- Recursive compression (<5KB)
|
||||
|
||||
```zig
|
||||
if (context.shouldLazyVerify()) {
|
||||
// Queue for batch
|
||||
try batch_queue.enqueue(proof);
|
||||
return .valid; // Optimistic
|
||||
} else {
|
||||
// Immediate verification
|
||||
return winterfell_verify(...);
|
||||
}
|
||||
```
|
||||
|
||||
## Build Instructions
|
||||
|
||||
### Prerequisites
|
||||
|
||||
```bash
|
||||
# 1. Install Rust
|
||||
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
||||
|
||||
# 2. Clone Winterfell
|
||||
git clone https://github.com/novifinancial/winterfell.git
|
||||
cd winterfell
|
||||
|
||||
# 3. Build with C FFI
|
||||
cargo build --release --features ffi
|
||||
```
|
||||
|
||||
### Zig Build
|
||||
|
||||
```bash
|
||||
cd src/access-toll
|
||||
|
||||
# Link with Winterfell
|
||||
zig build-exe toll_verifier_winterfell.zig \
|
||||
-lwinterfell_ffi \
|
||||
-L/path/to/winterfell/target/release
|
||||
|
||||
# Run tests
|
||||
zig test toll_verifier_winterfell.zig \
|
||||
-lwinterfell_ffi \
|
||||
-L/path/to/winterfell/target/release
|
||||
```
|
||||
|
||||
## Integration Points
|
||||
|
||||
### RFC-0130 (ZK-STARK)
|
||||
- **STARK #10**: TollClearanceCircuit (this implementation)
|
||||
- **Recursive Compression**: Kenya mode (<5KB)
|
||||
- **Proof Options**: Optimized for mobile (80 queries, 4x blowup)
|
||||
|
||||
### RFC-0205 (Passport)
|
||||
```zig
|
||||
// Nullifier derived from Passport soul key
|
||||
const nullifier = Nullifier.derive(commitment, passport.soul_key);
|
||||
```
|
||||
|
||||
### RFC-0648 (Hamiltonian)
|
||||
```zig
|
||||
// Dynamic toll adjustment
|
||||
const band = hamiltonian.calculate(v_measured, dt);
|
||||
assert(band.contains(proof.toll_band.target));
|
||||
```
|
||||
|
||||
### Membrane Agent Runtime
|
||||
```zig
|
||||
// Agent pays toll before resource access
|
||||
const proof = try generateTollProof(...);
|
||||
const result = try router.verifyToll(proof, context, v_measured);
|
||||
```
|
||||
|
||||
## Privacy Guarantees
|
||||
|
||||
| Leaked | Protected |
|
||||
|--------|-----------|
|
||||
| Commitment Hash (opaque) | Wallet Address |
|
||||
| Toll Band (range) | Exact Amount |
|
||||
| Nullifier (anti-replay) | Payer Identity |
|
||||
| Payment Occurred | Payment Method |
|
||||
|
||||
**STARK Properties:**
|
||||
- Zero-knowledge: Verifier learns nothing beyond validity
|
||||
- Succinct: ~5KB proofs (Kenya recursive)
|
||||
- Transparent: No trusted setup
|
||||
|
||||
## Performance
|
||||
|
||||
| Metric | Target | Notes |
|
||||
|--------|--------|-------|
|
||||
| Proof Size | 5-10 KB | Raw STARK |
|
||||
| Recursive Size | <5 KB | Kenya compression |
|
||||
| Proof Time | 1-5s | Client-side |
|
||||
| Verify Time | 10-50ms | Router-side |
|
||||
| Batch Verify | 100 proofs/200ms | Lazy mode |
|
||||
|
||||
## Next Steps
|
||||
|
||||
- [ ] Winterfell FFI bindings (actual C ABI)
|
||||
- [ ] Recursive compression (FRI folding)
|
||||
- [ ] QVL trust-scaled discounts
|
||||
- [ ] Membrane L1 integration
|
||||
- [ ] Router load testing
