dgb-oracle-ledger

The DigiDollar oracle signing-participation ledger: a walk over every DigiByte mainnet coinbase since DigiDollar activation (height 23,869,440), decoding the OP_ORACLE price bundle each block carries and recording which of the 35 oracle slots are set in its participation bitmap. Published at dgbinsights.com/oracles with per-epoch rows, per-slot totals, daily series, an absence-association matrix, and a provenance manifest per snapshot.

Read METHODOLOGY.md first. The bitmap is the signing set the MuSig2 aggregator chose for that epoch — a lottery-selected threshold subset of the oracles that participated — so the figures here are signing participation, never uptime or liveness. Slots are numbers. No operator identity is ingested or published.

Run

npm install                      # pulls dgb-digidollar-codec (the decoder lives there)
npm run walk                     # resumable explorer walk → data/blocks.jsonl
npm run aggregate                # snapshot at tip−720 → data/snapshots/<id>/
npm test

Environment: EXPLORER (default https://digiexplorer.info/api), START, CONCURRENCY (default 24), OUT, SETTLE (default 720), SNAPSHOT_END.

• src/rawblock.js — raw block reader (header + coinbase outputs), no external deps
• src/walk.js — chunked, hash-chain-checked, resumable walk; one JSONL row per height
• src/aggregate.js — epochs (one observation per unique epoch + signature), per-slot totals, 24-hour-delayed daily series, phi absence association, coverage, invariants, snapshot manifest, SHA256SUMS
• schema/oracle-ledger.schema.json — row shapes
• snapshots/ — manifests and checksums of published snapshots (data lives on the site)
