Sufficiency

Only one source (S1) is provided, which discusses Arc's BFT consensus achieving sub-second finality. This partially addresses the comparison between onchain replication and traditional settlement systems, but it does not cover traditional systems' centralized validation speed or the probabilistic nature of finality in other onchain systems. Coverage for sub-claims 2, 3, and 4 is low or zero, so more sources are needed.

Sub-claim "Onchain replication requires network-wide agreement, making …": 50% covered by S1, S2 — S1 mentions BFT consensus gives deterministic finality, but S2 implies probabilistic finality on Ethereum. Partial coverage.

Re-evaluate

Claims 2 and 4 have low coverage. CoinDesk (price 0.002) likely discusses onchain vs traditional settlement, covering both claims. Other skipped sources are either irrelevant or too expensive.

Adjudicate

⚖️ Sources disagreed on x402 payment finality time — S1 x402 batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) on Arc testnet. vs S2 x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time. → trusted S1 (S1 provides specific, measured latency data from testnet benchmarks, while S2 is based on a general reading without empirical evidence. S1's sub-second finality is also consistent with Arc's BFT consensus design.)

§ IIThe reading3 cited

Moderateconfidence— 3 sources cited, 3 sub-claims thinly covered, 1 disagreement adjudicateddeep research

Onchain databases achieve finality through consensus mechanisms that require network-wide agreement, making finality probabilistic until sufficient confirmations occur, whereas traditional settlement systems use centralized validation for faster, deterministic finality. For example, Arc's BFT consensus delivers sub-second finality (median 178ms) , while Ethereum L1 block times are around 15 seconds . However, onchain replication can also provide instant finality for certain assets like USDC, which settles peer-to-peer in seconds . The trade-off between decentralization and finality speed is a key difference: onchain systems prioritize decentralization and programmability, while traditional systems prioritize speed through centralization.
