Layer-1 Blockchains evaluated across documented downtime, measured and deterministic finality, validator count and Nakamoto coefficient, and independent client implementations.
Ranked here: Layer-1 blockchains, the base chains themselves, for a reader choosing one on halts, finality and decentralisation. Not ranked here: sidechains, Layer 2 rollups, modular data availability networks, former Layer 1s that now run as a Layer 2, and chains whose operating identity has been retired.

What matters most before choosing in this category
Weighted on documented downtime (30), measured deterministic finality (25), validator count and Nakamoto coefficient (25), and independent client implementations (20). The heaviest is documented downtime: Every full mainnet halt on the public record, with date, duration and root cause.
Can your use case tolerate a chain halt, or does it have to keep settling?
How many independent node clients does the chain run, and does that matter to you?
Does your use case need deterministic finality, or is probabilistic settlement acceptable?

Proof-of-stake settlement layer, largest validator set, slowest finality
Proof-of-stake settlement layer, largest validator set, slowest finality. Strongest on documented downtime (9/10): Ethereum states it has run continuously since 2015 without a single second of downtime, and no full mainnet halt is on the public record; the May 2023 loss-of-finality periods count as degraded performance. The record holds at about 25.6 tx/s. Weakest on validator count and Nakamoto coefficient (2/10): Chainspect shows a Nakamoto coefficient of 5 across 815,294 validators and $99.8B of stake, the lowest coefficient of the eight chains. The validator count fell from 1,351,000 as validators consolidated, so fewer keys do not mean fewer operators. Published price: Chainspect, an independent third-party chain tracker (chainspect.app/chain/ethereum, fetched 3 November 2026); Average Transaction Fee (1D): "$0.142" · On-Chain Revenue (1D): "$268K" · Block Time (1H): "11.96s" · Finality Time: "12m 48s".
Best forDocumented Downtime — 9/10
Main tradeoffThe 12m48s finality and the 43-day, 2,483,581 ETH validator entry queue (validatorqueue.com) are structural, not transient. And Ethereum's client-diversity advantage is partly unmeasurable: its own two canonical telemetry sources disagree on which client is dominant, so nobody can state the actual supermajority risk with confidence.

Ethereum publishes no fee schedule of its own; these are network-wide 1-day or 1-hour averages, not a price for one transaction.

Frequently asked
Questions people ask before choosing L1 chains
What is the safest Ethereum Layer-1?
Safety here comes from whether the chain keeps producing blocks and whether finality is a guarantee or a statistic. Halts are the only chain property that is unambiguously observable and dated — every other metric is contestable, and halts cluster by root cause, because the thing that produced one is usually still there.
Why is TPS not in the ranking?
Because theoretical throughput is a marketing number. One chain here advertises 104,715 TPS against a measured maximum of 1,542 — a 68-fold gap between claim and demonstration. Measured throughput is used where it is independently published, and where it is not, that absence is stated rather than filled.
Is a high validator count the same as decentralisation?
No, and this category's most uncomfortable result comes from that gap. Nakamoto coefficient asks how many parties must agree to censor or halt you, and measured independently, the chain with the largest validator set in this pool scores 1 — worse than a chain with 45 validators. Validator headcount is shown as a fact; the coefficient is what is scored.
