Recalled 59 past runs on this subject — how these sources performed when they were available.
ERC-8004 reputation loaded — composite scores on this subject.
Primary source with exact match on question topic; cached, so reuse free. Contains lab-measured latency and finality benchmarks for x402 on Arc testnet, directly answering the query.
Low reputation (1/100) but highly relevant cached source on x402 settlement timing. Provides comparative overview that complements Arc-specific benchmarks.
High-reputation source (32/100) with strong citation history on settlement; cached. Provides context on stablecoin finality mechanics, but less specific to Arc latency measurements.
Moderate-reputation source (15/100); cached. Covers x402 standard and agent payments, offering complementary context on why settlement latency matters for agents.
Cached; Ethereum-focused, but previews show cryptography and LLM topics, not Arc-specific latency data.
Low-reputation (5/100); cached. General consensus/database concepts are too broad for specific x402 finality insights.
Zero reputation on this subject; cached. Stripe's dispute and payment trends are not about on-chain settlement latency.
Zero reputation on this subject; cached. Ethereum updates are not specific to x402 finality measurements on Arc.
Not cached, low topical fit; news articles rarely provide detailed benchmark data on finality latency.
AI-focused newsletter; cached. Covers agent infrastructure but lacks specific x402 settlement benchmarks.
Not cached; general crypto news unlikely to contain measured settlement latency data.
Zero reputation on this subject; not cached. News and analysis lack specific benchmark results for Arc finality.
Lower-reputation (22/100) and less focused on finality specifics; cached. Micropayment batching principles are tangential, not core to Arc latency measurement.
AI/LLM tools blog; cached. No direct coverage of blockchain settlement latency.
Not cached; ML/deployment focus is unrelated to x402 finality measurements.
Zero reputation on this subject; cached. Regulatory and exchange news, not technical finality benchmarks.
High reputation (100/100) but completely off-topic (gardening). No relevance to settlement latency or finality.
High reputation (100/100) but irrelevant (retro gaming hardware). No connection to x402 or Arc finality.
Cached; occult/esoteric content is entirely irrelevant to settlement latency.
Cached; general tech/lifestyle articles with no blockchain settlement focus.

Sub-claim "x402 settlement latency on Arc provides a quantitative measu…": 100% covered by S1 — S1 directly gives measured median 178ms and p95 240ms across thousands of submitBatch calls, explicitly describing this as finality on Arc.
Sub-claim "The measured latency on Arc reflects the time required for t…": 90% covered by S1 — S1 states batched settlements finalize in roughly 180ms via BFT consensus delivering sub-second finality; finality in BFT consensus is understood as irreversible, though the source does not use the word 'irreversible'.
Sub-claim "The observed latency values reveal Arc's finality characteri…": 70% covered by S1 — S1 contrasts Arc's sub-second BFT finality with block-time-bound Ethereum L1 transactions, giving a qualitative relative comparison, but lacks explicit comparative latency figures for other networks.
No sub-claim has coverage below 0.5, and existing gathered sources adequately support the core assertions. Additional sources are unnecessary given the remaining budget constraints and frugality requirement.

Final coverage assessment — S1 directly reports measured x402 settlement latency on Arc (178ms median, 240ms p95) and frames it as sub-second BFT finality, explicitly contrasting it with Ethereum L1 block-time. This quantitatively supports the first sub-claim, supports finality-as-irreversible-confirmation by equating 'finalize' with BFT finality, and positions Arc relative to another network.
Synthesizing a grounded answer from 4 source(s)…
⚖️ Sources disagreed on x402 settlement latency/finality time on Arc — S1 Sub-second finality: measured median 178ms, p95 240ms on Arc testnet vs S2 About 15 seconds, similar to Ethereum L1 block time, because each payment is its own transaction → trusted S1 (S1 reports direct measured data across thousands of submitBatch calls on Arc testnet with BFT consensus, while S2 is an interpretive estimate ('in our reading') not based on Arc measurements.)
Verified — S1 supports claim 1 at 100%: “Across thousands of submitBatch calls on Arc testnet, x402 batched settlements finalize in roughly 180 milliseconds (measured median 178ms, …”
Verified — S1 supports claim 2 at 100%: “Arc's BFT consensus delivers sub-second finality, so a Gateway-batched payment confirms in well under a quarter second”
Verified — S1 supports claim 3 at 100%: “it is not block-time-bound the way an Ethereum L1 transaction is.”

Measuring x402 settlement latency on Arc provides a direct quantitative measure of finality: across thousands of submitBatch calls, batched settlements finalize in roughly 180 ms (measured median 178 ms, p95 240 ms) . This latency is the time until confirmation under Arc's BFT consensus, which delivers sub-second finality; a Gateway-batched payment confirms in well under a quarter second . Compared with other networks, this is not block-time-bound the way an Ethereum L1 transaction is .
