Reused cached Onchain Micropayments Digest — Nanopayments and the $0.000001 floor (free) — S1

Sub-claim "What does Onchain Micropayments Digest establish about the c…": 80% covered by S1 — S1 explicitly states nanopayments push the minimum economical payment to about $0.000001 via off-chain authorizations settled in batches, avoiding per-transaction gas, making sub-cent payments viable. This directly answers the mechanism and the floor claim, though it is an abstract and lacks quantitative verification detail.

Sub-claim "What remains uncertain about the claimed $0.000001 nanopayme…": 10% covered — S1 provides no statement of uncertainty, caveats, or open questions about the $0.000001 floor. The abstract asserts the floor without discussing what remains uncertain, so this sub-claim is essentially unaddressed.

The first sub-claim is well covered by S1 (0.8). The second sub-claim is poorly covered (0.1), but none of the affordable skipped sources (all ≤0.004, within the 0.015 budget) address uncertainty about the $0.000001 nanopayment floor. The closest candidates—Arc Settlement Benchmarks and Web Payments Review—concern x402 settlement latency, not the nanopayment floor's uncertainty. Buying them would not fill the gap, so no purchase is recommended.

Final check — "What does Onchain Micropayments Digest establish about the c…": 100% assessed by S1

Final check — "What remains uncertain about the claimed $0.000001 nanopayme…": 0% assessed

Final coverage assessment — The supplied abstract from Onchain Micropayments Digest directly addresses the first sub-claim: it establishes that nanopayments push the minimum economical payment to about $0.000001 by signing off-chain authorizations and settling them in batches, avoiding per-transaction gas. It does not, however, state what remains uncertain about that floor. No passage discusses uncertainty, caveats, limitations, or open questions, so the second sub-claim is not covered. The assessment does not establish a complete supported answer for every requested part.

Synthesizing a grounded answer from 1 source(s)…

Relevance review returned; only checked excerpts can retain support, and review cannot raise it.

Verified — S1 supports claim 1 at 100%: “Nanopayments push the minimum economical payment to about $0.000001 by signing off-chain authorizations and settling them in batches.”

Below reward gate — S1 supports claim 1 at 20%: “Instead of paying gas per transaction, many micro-authorizations settle together.”

Below reward gate — S1 supports claim 2 at 10%: “This makes paying a creator a fraction of a cent per citation actually viable.”
