+
+## Dataset Description
+
+### Dataset Summary
+
+OpenChainBench publishes reproducible, daily-refreshed performance
+benchmarks for crypto infrastructure providers. Each benchmark answers
+one operational question (for example, "which RPC has the lowest p50
+latency for `eth_getBlockByNumber` on Ethereum?") and reports it as a
+ranked leaderboard with p50 / p90 / p99 percentiles, success rate, and
+per-provider sample sizes. This dataset is a frozen, ML-friendly
+projection of that live data, partitioned by `snapshot_date` so the
+full history is queryable from a single Parquet scan.
+
+Use cases the dataset supports:
+
+- Time-series forecasting of provider latency / cost / success rate.
+- Tabular regression over provider attributes (type, layer, sample size).
+- Reproducibility for citations made on the live site (each row carries
+  the same `citation_url` you would link to in a paper or blog post).
+- Anomaly detection on infrastructure trajectories across the
+  industry-wide registry.
+- Powering AI agents that need an authoritative, citable answer to "who
+  leads on metric X today?"
+
+### Supported Tasks and Leaderboards
+
+- `time-series-forecasting`: each `(bench_slug, provider_slug, window)`
+  tuple in the `timeseries` config is a univariate series suitable for
+  forecasting.
+- `tabular-regression`: the `providers` config exposes per-provider
+  numeric features (p50 / p90 / p99 / mean / success rate / sample
+  size) and categorical features (type / layer / tag) per snapshot.
+- `other` (information retrieval / agent grounding): the `headlines`
+  config is shaped to fit into a single LLM tool call. Agents reading
+  it get the headline number, the leader, the methodology link, and the
+  citation URL in one row.
+
+A live leaderboard for every benchmark is at
+`https://openchainbench.com/benchmarks/<slug>`.
+
+### Languages
+
+The dataset is monolingual: English (`en`). All text fields (title,
+category, metric, unit) are English. Provider names are project
+trademarks and preserve their original casing.
+
+## Dataset Structure
+
+### Data Instances
+
+Each config is a flat Parquet table partitioned by `snapshot_date`.
+A row looks like (headlines):
+
+```json

+
+### Data Splits
+
+Every config exposes a single `train` split. There is no held-out
+evaluation split because the dataset is observational: it records
+measurements as they happen and downstream users define their own
+train / test cuts (typically by `snapshot_date`).
+
+## Dataset Creation
+
+### Curation Rationale
+
+The OpenChainBench site renders human-readable leaderboards but its
+underlying JSON feeds are designed to be agent-friendly: every value
+is paired with a methodology link, a license, and a sample size. This
+dataset freezes those feeds daily so:
+
+- LLM agents and journalists can cite a deterministic snapshot.
+- ML researchers can train models without depending on a live API
+  whose numbers move every minute.
+- Operators can compare today's leader against arbitrary historical
+  baselines without rebuilding the harness.
+
+### Source Data
+
+#### Initial Data Collection and Normalization
+
+Raw measurements are collected by per-bench harnesses (open-sourced in
+the [OpenChainBench GitHub repo](https://github.com/ChainBench/OpenChainBench)
+or, for a few benches, in a private mobula-api repo where they exist
+behind paid API keys). Harnesses publish Prometheus metrics that the
+OCB Next.js app aggregates into a `Benchmark` object per bench.
+
+The dataset publisher reads from:
+
+- `https://openchainbench.com/api/citable` for the headline feed.
+- `https://openchainbench.com/api/stat/<slug>` for per-bench detail
+  (provider rankings, sparkline, `higherIsBetter`).
+- `https://openchainbench.com/api/series/<slug>?range=<window>` for the
+  24h / 7d / 30d per-provider trajectories.
 
-## Tables
+Each per-bench page documents its full methodology. The
+`citation_url` column of `headlines` is the stable link to that page.
 
-| Config | Grain | What's in it |
-|---|---|---|
-| `headlines` | 1 row per (bench, day) | Title, metric, leader, headline value, license, source URL |
-| `providers` | 1 row per (bench, provider, day) | p50/p90/p99, mean, success rate, sample size, is_leader flag |
-| `timeseries` | 1 row per (bench, point, day) | 24h sparkline values (~72 points per bench) |
+#### Who are the source language producers?
 
-All tables are partitioned by `snapshot_date=YYYY-MM-DD`. Each row also
-carries a `captured_at` timestamp (UTC, ISO 8601) and a `schema_version`
-integer.
+All text fields (titles, methodology copy, category labels) are
+authored by OpenChainBench contributors in the YAML benchmark specs
+under `benchmarks/` in the GitHub repo. The data values themselves are
+machine-generated by the measurement harnesses.
+
+### Annotations
+
+The dataset has no human-applied annotation layer. Provider rankings
+and leader flags are derived programmatically from the percentile
+measurements according to each bench's `higher_is_better` direction.
+
+#### Annotation process
+
+The OCB Next.js layer computes the leader as the provider with the
+best `p50` according to the bench's direction. `bestPerChain` and
+`worstPerChain` (when populated) are computed with the same rule
+scoped to chain-restricted samples. The `is_leader` boolean in the
+`providers` table is a derived projection of `headlines.leader_slug`.
+
+#### Who are the annotators?
+
+There are no human annotators. Categorical fields like `category`,
+`metric`, `unit`, `provider_type`, and `provider_layer` are authored
+by the bench YAML maintainers and reviewed via the same PR process as
+the harness code.
+
+### Personal and Sensitive Information
+
+The dataset contains no personal or sensitive information. Provider
+identifiers refer to operational entities (companies, networks, public
+APIs) and are publicly listed on the OpenChainBench site.
+
+## Considerations for Using the Data
+
+### Social Impact of Dataset
+
+Public, reproducible measurements of crypto infrastructure raise the
+bar for operator transparency. Downstream consumers should not, however,
+treat any single snapshot as definitive: providers' production
+characteristics change with traffic, deployments, and incident
+recovery.
+
+### Discussion of Biases
+
+- **Vantage bias**: latency benchmarks are scraped from a small set of
+  Prometheus harnesses located in specific cloud regions. The exact
+  vantage points and methodology are documented per bench at
+  `citation_url`.
+- **Sample asymmetry**: providers that rate-limit our probes hard end
+  up with smaller `provider_sample_size` than providers that allow
+  generous quotas. This biases percentile estimates upward (fewer
+  samples surface tail latency less reliably). The `is_leader` flag is
+  derived purely from the p50 figure and may therefore reflect
+  measurement-side asymmetry, not just provider performance.
+- **Aggregator coverage**: providers that wrap multiple upstream APIs
+  (aggregators, with `provider_type = "aggregator"`) compete on a
+  different surface than single-vendor providers and are not strictly
+  apples-to-apples comparable. The `provider_type` column is meant to
+  let consumers filter or stratify by this distinction.
+
+### Other Known Limitations
+
+- **Schema stability promise (additive only)**: new columns may be
+  added without warning. Consumer queries should select named columns
+  rather than `SELECT *`. Existing columns are never renamed or
+  removed within a `schema_version`. If a breaking change is
+  unavoidable, a parallel v3 / v4 folder ships alongside the v2
+  partitions so old consumers keep working.
+- **`chain_leaders` is currently empty**: the `bestPerChain` /
+  `worstPerChain` data exists inside the OCB aggregator but is not
+  exposed by `/api/citable` or `/api/stat` yet. The table is shipped
+  with its canonical schema so downstream pipelines can stabilize
+  against a real (zero-row) parquet today and start receiving rows
+  as soon as the API surfaces the field. Tracked in the publisher's
+  source code as a `TODO`.
+- **24h legacy fallback**: when `/api/series` returns no payload for a
+  bench's 24h window, the publisher falls back to the aggregate
+  `sparkline` from `/api/stat`. Those fallback rows carry the leader's
+  `provider_slug` rather than a per-provider series; downstream users
+  who care about per-provider trajectories should filter on `window in
+  ('7d', '30d')` or join `provider_slug` against the `providers`
+  config.
+- **Quorum guard**: if the source feed reports fewer than half its
+  benches as `live` on capture day, the publisher refuses to upload a
+  new partition. The previous good snapshot stays as truth that day.

-## Methodology
-
-Each benchmark documents its full methodology on the OCB site (per-bench
-URL is in the `citation_url` column of `headlines`). Reading list:
-
-- Per-bench page (open methodology): `https://openchainbench.com/benchmarks/<slug>`
-- Site-wide methodology: `https://openchainbench.com/methodology`
-- YAML spec source (Apache 2.0): `https://github.com/ChainBench/OpenChainBench/tree/main/benchmarks`
-
-Harness code is open source where applicable (column `source_url`).
-
-## Schema stability promise
-
-- New columns may be added without warning. Consumer queries should
-  select named columns rather than `SELECT *`.
-- Existing columns will never be renamed or removed. If a breaking
-  change ever proves unavoidable, a parallel v2 folder ships alongside
-  the v1 partitions so old consumers keep working.
-- `schema_version` integer in each row marks the additive schema epoch.
-
 ## Update cadence
 
 Snapshots run daily at 00:00 UTC via a GitHub Action. If a run aborts
 on a quorum check (the source feed has fewer than half its benches
-live), no new partition is added that day - the previous good snapshot
+live), no new partition is added that day. The previous good snapshot
 stays as truth.
