Independent ingestion of Qubic Useful-Proof-of-Work data: mining solutions read directly from on-chain transactions, the solution threshold read from our own node, and computor balance snapshots taken at every epoch boundary. This page shows collection progress only — per-epoch quality and reward metrics will appear on a separate page once full epochs are ingested and computed.
Latest epoch with ingested solutions
Epoch 230, read from our node (GetSystemInfo). A solution is valid when its error score ≤ threshold.

Distinct identities that submitted a scored solution
Lowest error count seen so far (lower is better); miner-declared, node-verified
Mining solutions are transactions to the zero address (inputType 2, 1M+ qus deposit). The claimed error score is part of the transaction payload. BPP-9000 scoring is active since epoch 224 — earlier epochs use a different algorithm and are intentionally not collected.

Per-computor reward payouts are protocol-level balance emissions and are not exposed by any public API. We reconstruct them as the balance difference of all 676 computors across each epoch boundary (net of visible transfers). pre = last snapshot before the boundary, post = first snapshot after it. History starts 2026-08-25 — earlier boundaries cannot be backfilled.

The validity threshold is a per-epoch value set by network operators and can change mid-epoch. It is read hourly from our own node; every observed change gets its own row.

All figures on this page are derived exclusively from data we ingest ourselves: solution transactions from the public Qubic archive (rpc.qubic.org), the solution threshold from our own Qubic lite node, and balance snapshots from the public balance API. Claimed scores are declared by miners and verified by network nodes before the submission deposit is returned; independent re-scoring of a sample with the canonical scorer is planned. Solution data covers epoch 224 onwards (BPP-9000 activation) — older epochs used a different scoring algorithm and are not comparable.
