A complete selection, from commitment to report

On 4 September 2026, EigenSelect submitted a two-outcome coin selection to the production service. Payment alone was bypassed with a reservation code. The commitment, physical execution, publication and delivery machinery was the same path used for a paid selection.

This transaction was operated by EigenSelect as a production smoke test and has been deliberately designated as a public example. Ordinary customer outcomes and reports remain private to the holder unless the holder chooses to share them.

The selection resolved to

Heads

Bitstring 0 · one shot · one physical execution · no rejected measurements

What happened

  1. The selection was fixedHeads and Tails were canonicalized as two outcomes. A manifest committed to the outcome set, state mapping, backend, one-shot rule, rejection policy and transpiled circuit.
  2. The commitment was publishedAt 2026-09-04T14:31:00Z, the manifest digest was published to the DNS proof zone and to public Nostr relays before the processor was contacted.
  3. The circuit ran onceThe job was submitted at 2026-09-04T14:31:03Z and completed at 2026-09-04T14:31:12Z on QPU-EMERALD-54PQ · IQM Crystal-54. The measured bitstring was 0, which decoded to the in-domain state 0.
  4. The resolution closed the chainHeads was resolved at 2026-09-04T14:31:13Z. The resolution digest was then published to DNS and Nostr, and the report was rendered from the verified evidence.

The first command reads the digest that was visible before execution. The next two hash the canonical manifest and exact QASM circuit served by the application. Their output must match the manifest and circuit digests above.
