Layer 1 blockchains
9 layer 1 blockchains with the facts we checked on each project’s own pages.
This directory lists every layer 1 blockchain we have a profile for. Each card shows the chains, platforms and custody model stated by the project. For our ranked picks with pros, cons and who should skip each one, see Best Layer 1 Blockchains.

FAQ
Which layer 1 blockchain ranks first on DappAtlas?
Ethereum is #1 in our list “Best Layer 1 Blockchains” (updated Sep 26, 2026). Ethereum has run since July 30, 2015 and switched to proof-of-stake on September 15, 2022. Blocks come in fixed 12-second slots, and its clients, such as Go Ethereum, are open source.
How is this directory ordered?
Projects ranked in “Best Layer 1 Blockchains” come first, in the order of that list; the rest follow alphabetically. The directory itself does not score projects.
Which layer 1 blockchains are open source?
Of the 9 listed, 8 state that their code is open source: Ethereum, Solana, Bitcoin, BNB Chain, Avalanche, Sui, NEAR Protocol, Aptos.
