# zkPerf: Proven Performance Witness Dataset

Reproducible perf recordings built inside nix derivations. Every number is real, captured by hardware PMU counters. Nothing is fake.

## Proven Counters

| Counter | Value | Source |
|---|---|---|
| cycles | 1,586,731 | `perf stat` in nix sandbox |
| instructions | 1,838,067 | `perf stat` in nix sandbox |
| cache-misses | 5,790 | `perf stat` in nix sandbox |
| branch-misses | 9,589 | `perf stat` in nix sandbox |

CPU: 12th Gen Intel Core i9-12900KF, kernel 6.8.0-94-generic, perf 6.19.8

## Chain

```
binary (zkperf-0.1.0)
→ record (perf record -g --call-graph dwarf,65528 -c 100 -e cycles:u,instructions:u,cache-misses:u,branch-misses:u)
→ analyze (per-event top functions + full report)
→ export (NAR archives + eRDFa witness)
→ COMMITMENT: bb5f619f57cd141bf343f20a41e50f7e08cf1508899d05562f23ca7542c89d96
```

## Structure

```
data/
witness/ # perf stat with proven counter values
record/ # perf.data + perf-report + perf-annotate + perf-script
analyze/ # per-event top functions, analysis.json, full-report
export/ # NAR archives, eRDFa witness HTML/JSON, chain commitment
shards/ # 6,374 eRDFa CBOR shards (CFT decomposition of all text data)
```

## Reproduction

```bash
git clone https://github.com/meta-introspector/zkperf
cd zkperf
nix build .#zkperf-export
cat result/COMMITMENT
```
