Why this rank
Why World ID ranks #4
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (23.4 here) sit inside the score; availability, friction, trust record and measured data add the rest. Best in this ranking on 1 of 4.

What would move the rank
Each line is the ranking run again with one of World ID’s criterion scores changed and every other value held: the smallest whole-point change on that criterion that moves its rank, and where the re-run puts it. Up to 4 climbs and 3 falls are listed, smallest change first. Nothing here is a forecast.

Record watch-outs
- The five-chain deployment is not one security domain, and it is more fragmented than a single headline number suggests: the same owner address is a 4-of-6 Safe on Ethereum, a 2-of-5 on World Chain and a 2-of-7 on Optimism, while the Base and Polygon routers are owned outright by externally owned accounts that can repoint group 1 with updateGroup. Polygon's bridged root also lags the canonical one by roughly a day, so a proof minted against the current tree can fail on Polygon until the bridge catches up.
Competitive position
Where World ID leads and where it trails
Rank on every objective dimension among the rows scored on it. A criterion in the top third of its pool is listed as a lead, the bottom third as a trail; the middle is neither. Popularity, size and commercial terms are not dimensions.

Against the leader
81 vs 74 · gap 7.0Why Idena ranks above World ID
The compare workspace's arithmetic applied to these two rows. Each dimension's share of the gap is its weight × the difference, on the displayed scale — it reproduces the displayed gap of 7.0 to within rounding.

Facts
facts, not scoresWhat the record publishes
- Pricing
- "Usage will remain free for end users while applications will be charged for using World ID services. Each credential issuer will be able to set and retain their own credential fee, while a separate protocol fee will flow back to the protocol itself." and, further down the same page, "The World ID smart contract will require fees to be paid in WLD" (World's "Introducing World ID Fees" post, re-fetched 28 September 2026, HTTP 200). No fee schedule, rate card or WLD amount is published anywhere on the page; the pricing mechanisms it lists (per-proof, per-monthly-active-user, free tiers, volume discounts) are options, not prices, and the page's own outlook, "The Foundation expects to complete this work and run a first pilot to test the fee mechanism during Q3 2025.", has passed without a published rate. The page now carries the banner "The information in this article is over 12 months old and may be outdated." The World developer docs index (docs.world.org/llms.txt, HTTP 200) lists no World ID pricing page either.World ID — official pricing page ↗ · 28 September 2026

Changes to published ranks are recorded in a ledger; every step and its cause is listed on the rank-history page. The entries below begin with the current verified snapshot, then the methodology versions whose changes applied to this category, newest first.

- 10 October 2026
2026.10.8When nothing serves your country, the list shown for reference is the published ranking · platform-wide- fixed The reference list shown when nothing serves your country is the published order with the published scores, and a build check now fails any such list out of that order or with a score the ranking does not publish.
- fixed The explorer prints an overall rank only for a row the published ranking holds; a country entrant such as Coinbase Commerce for US merchants shows no overall rank.
- changed Published orders do not move. Country results change only where nothing serves the country: in India bill pay keeps Bitcoin Well first and now shows Strike second, as published; 35 such runs across all categories and countries now match the published list exactly.
- 10 October 2026
2026.10.6A criterion you require re-scores the rows that meet it · platform-wide- changed The explorer sends each criterion you require, at any band, as fit_required with your other answers; region, licence, chain and fact filters stay filters. On /best, a required criterion joins For you as a marked preference does, which needs your country; Overall stays the published ranking, filtered.
- added Every published criterion has a golden case as the explorer sends it (require:<criterion>), so the order a requirement gives is replayed and gated as the published order is, and a change to it needs an entry here.

2026.09.15Dimension scores carry tenths, and eleven more categories are re-read from primary sources · platform-wide- changed Dimension scores resolve to tenths of a point (O-04b), and weightedTotal is rounded to six decimal places before the order is read. 518 published scores move across 107 categories that were not re-read; none of them moves by more than 4 points, and most move by 1.
- fixed 66 published scores change in the eleven re-read categories, against a verbatim source each. The largest moves are Reflexer RAI (−16), Beefy and Unrekt (−11), Aztec (−10) and Golem (+9) — all of them rows whose sources had moved since their last read.
- changed Published order moves in 38 of 119 categories and three #1s change: smart_contract_audits (Zellic → Certora) and travel_rule_compliance (Sumsub Travel Rule → CodeVASP) on the finer resolution, kyc_compliance (Veriff → Sumsub) on the re-read.
- added availabilitySource (O-04g): for a reader who states a country, a row whose availability in that country rests on a region tag its record gives no source for sorts below every sourced row. It is inert in every order published here, which states no country.
