Filecoin (FIL) — the revision ledger

Generated 2026-10-18T05:19:42Z from live ClickHouse queries against this estate's ledger. Point-in-time archive held for Filecoin: 54,101 observations · 70 distinct series · 10 upstream sources · first row 2026-08-09 23:28:06 · newest row 2026-10-18 05:18:02 · every one of the 54,101 rows carries a verify_url · 56 series refreshed in the last 24h (1,224 fresh rows). Nothing on this page is cached, estimated, or remembered.

Provenance — where FIL's archive comes from

10 source families feed this network's ledger. Every row they wrote carries its own source, as_of and verify_url; this table is the live rollup of that. The first-party family is Filecoin's own public chain telemetry via Glif's endpoints (https://api.node.glif.io/rpc/v0) — chain head, epochs, network power and base fee from the network itself — with the estate's dedicated storage-power collector (committed and quality-adjusted bytes, verified-deal utilisation), DefiLlama's fees/dex/TVL/stablecoin series (the origin of the watched fees_alltime_usd counter), the CoinGecko market reference, and filecoin-project/lotus GitHub activity alongside.

Revision ledger — 0 backward revision(s) recorded for FIL

The ledger query ran during generation and returned 0 rows for FIL — and the reason is on this page, measured live: the detector files cumulative-by-construction series (counters that cannot decrease unless upstream rewrote them), and FIL's daily archive holds exactly two watched series of that class — BLOCK_HEIGHT from the estate's first-party collector and fees_alltime_usd from DefiLlama. Both full trails are tabled below: strictly monotonic across every snapshot the estate holds (2026-08-06 → 2026-10-17), so the detector has never had a rewrite to file. Zero here is the live query result plus the measured counter trails, not a gap — the ledger itself is at /v1/revisions?symbol=FIL (the same query this page ran, served live), and a restatement would appear on this page the day the detector records one. /v1/revisions?symbol=FIL cross-check passed: the served API reports 0 row(s), matching the ledger count rendered on this page.

The detector class, measured — FIL's watched counters

The detector diffs every daily snapshot of every cumulative-by-construction series. Below is the live intersection of the estate's cumulative watchlist with what the daily archive holds for FIL — and both watched series the archive holds are real hits: BLOCK_HEIGHT (the Filecoin chain height, from the estate's first-party collector) and fees_alltime_usd (lifetime fees, from DefiLlama). The trails that follow are every snapshot the archive holds of them, straight from the ledger.

BLOCK_HEIGHT — watched cumulative counter #1, every snapshot held, with its source. Strictly increasing across the whole archive: no date's value was ever replaced, so there is nothing for the detector to file from this series. This measured trail is part of the zero above.

fees_alltime_usd — watched cumulative counter #2, every snapshot held, with its source. Also monotonic across the archive: no date's value was ever replaced, so there is nothing for the detector to file here either. This measured trail is the other half of the zero above.

Gauges that moved backward — deliberately NOT revisions

These series fall outside the detector's cumulative-by-construction class (NOT_TRULY_CUMULATIVE in propintel/revision_ledger.py): a drop there is a real population or market change, not upstream rewriting history. Publishing them as "revisions" would be exactly the fake-metric behaviour this product exists to eliminate.

The sharpest FIL case: ACTIVE_MINERS — the live miner population from the estate's first-party collector — moved backward 11 times across the archive (537 → 517 among them) as miners join and leave. A naive monotonicity detector would file every drop as a restatement; the detector correctly classifies it as a population gauge. The full trail below is the worked example.

The intraday cumulative-class series: chain_epoch from Filecoin's own public RPC via Glif, observed hourly. Also strictly increasing across the archive — the same no-rewrite story as the daily watched counters, at hourly resolution.

Same-timestamp conflicting values on record for FIL: none

The task-level conflict check, run live: any (metric, timestamp) family where this estate recorded two or more different values. The query ran at generation and returned 0 groups in both depin_onchain and depin_daily — every (metric, timestamp) pair the estate holds for FIL carries exactly one value. Zero here is the live query result, not a gap; the archive kept every write it made, and none of them disagree.

The ledger, live — every restatement recorded estate-wide (39 deduped events)

Deduped on revision identity exactly as /v1/revisions dedupes it. This is the same feed a subscriber polls; it is rendered live from ClickHouse at generation, not copied from a snapshot. Each row is an upstream source replacing the value of a (network, metric, date) it had already published — after this estate recorded the original. The superseded value is retained, never overwritten; that retention is the only reason a rewrite is detectable, and it is the part every overwriting vendor discards.

How detection works — and what it cannot see

The detector (propintel/revision_ledger.py) diffs every daily snapshot this estate holds of every cumulative-by-construction series — counters that cannot decrease unless upstream rewrote them (block heights, transaction and transfer counters, lifetime fees). A row enters default.depin_revision_ledger iff two snapshots disagree for an already-observed date; zero human judgement. Resolution rule: latest observation wins for current-state reads, the superseded value is retained, never overwritten. Population gauges (miner sets, node counts, prices, capacity) legitimately move both ways and are deliberately excluded — a drop there is a real population change, not a rewrite; the ACTIVE_MINERS case on this page is the worked example. Honest boundary: this catches value-history rewrites ex-post; identical-schema semantic drift with plausible values is what the hash-pinned derivation_replay layer is for. The detector's full classification is inspectable at /v1/revisions and frozen daily at /revision-ledger/REVISIONS_20260902.json.

Verify any cell yourself — the exact commands

No account, no key, no trust required. Commands 1–2 hit this estate's public API (the same rows this page queried — every row carries source / as_of / verify_url); command 3 hits Filecoin's own public chain telemetry and command 4 DefiLlama's fees series, the origins of the watched counters; command 5 is the estate's graded network row; command 6 is the frozen daily snapshot of the ledger. One polite call per endpoint, no hammering.

Method & honesty notes. All counts are queries against the live ledger at generation time, not restamped copy — this page is regenerated by gen_revision_page_fil.py and the hourly claim_drift_check.py run grades its claims against the live API like every other published surface. The FIL revision count is the live result of SELECT count() FROM default.depin_revision_ledger WHERE network='FIL'; the page refuses to ship if the served /v1/revisions?symbol=FIL disagrees with it. The 39 estate-wide events shown are deduped on revision identity (deterministic hash of network, metric, current_date, prior_date) exactly as the API dedupes them; detected_at is the first detection and never moves. Series absent from a section are absent, not zero: the daily-snapshot ledger for FIL is genuinely empty today — the two watched cumulative series the archive holds (BLOCK_HEIGHT and fees_alltime_usd) have strictly monotonic trails, measured live in the tables above — and this page says so instead of inventing restatements. The same-stamp conflict check is likewise the honest live answer: 0 groups in both tables.
