Reused cached Onchain Micropayments Digest — Per-citation payments weighted by contribution (free) — S1

Reused cached Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc (free) — S2

Sub-claim "What does "Per-citation payments weighted by contribution" m…": 70% covered by S1 — S1 directly explains the model: each cited source is paid in proportion to its contribution to the final answer, with heavily-relied-upon sources earning more and lightly-used ones less, and multi-author works splitting a single reward. It does not explicitly name Keryx, so the Keryx-specific framing is a small gap.

Sub-claim "What does "gas" refer to in the context of Keryx's per-citat…": 0% covered — No supplied passage mentions gas at all. S1 discusses weighted nanopayments and settlement practicality but never defines or references gas; S2 covers x402 settlement latency on Arc, not gas.

Sub-claim "What does "Per-citation payments weighted by contribution" r…": 0% covered — Neither S1 nor S2 connects per-citation weighted payments to gas. S1 explains the weighting model but says nothing about gas; S2 addresses settlement latency, not gas costs or gas mechanics.

Coverage is adequate for the meaning of per-citation weighted payments (S1), but the gas-related sub-claims are entirely uncovered. Among affordable skipped sources (budget 0.02), only 'Web Payments Review — How long do x402 payments take to finalize?' plausibly touches payment-rail mechanics and could partially address settlement/fee context relevant to gas; it is the highest-priority affordable candidate. Other skipped sources are unrelated to Keryx citation payments or gas. Note that even this source may not directly define gas, so the gas gap may remain.

Final coverage assessment — The supplied passages only describe a general fair citation-payment model (S1) and x402/Arc settlement latency (S2, S3). None of them mention Keryx, define 'gas' in Keryx's per-citation payment context, or explain what per-citation payments weighted by contribution reveal about gas. S1 provides topical context for weighted per-citation payments but does not answer the Keryx-specific or gas-specific parts; S2 and S3 concern settlement timing, not gas or citation weighting. The assessment does not establish a complete supported answer for every requested part.

⚖️ Sources disagreed on x402 payment settlement timing — S2 x402 batched settlements on Arc finalize in roughly 180 milliseconds (median 178ms, p95 240ms), with sub-second finality and not block-time-bound like Ethereum L1. vs S3 An x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time, because each payment is its own transaction waiting to be mined into a block. → reported preference: S2 (S2 reports specific measured benchmarks (median 178ms, p95 240ms across thousands of submitBatch calls) and explains the mechanism (Arc BFT consensus, Gateway batching), making it more specific and internally consistent than S3, which is explicitly framed as a reading/view and offers no measurements.)

Verified — S1 supports claim 1 at 90%: “A fair model pays each cited source in proportion to its contribution to the final answer.”

Verified — S1 supports claim 1 at 80%: “Heavily-relied-upon sources earn more; lightly-used ones earn less.”

Verified — S1 supports claim 1 at 50%: “Weighted nanopayments make this granular settlement practical, and multi-author works can split a single reward across contributors automati…”
