Independent consensus, independent token, independent security model. Each L1 is a sovereign network running its own time and its own truth. The base layer everything else builds on top of.
Layer 1s are the substrate. Ethereum, launched July 2015 by Vitalik and a founding crew including Gavin Wood, Joe Lubin, and Charles Hoskinson, gave the world programmable money via the EVM. The DAO hack in 2016 forked the chain and birthed Ethereum Classic. The Merge in September 2022 ended proof-of-work on mainnet and cut energy by ~99.95 percent. Dencun in March 2024 introduced EIP-4844 blobs and dropped L2 fees by an order of magnitude. The roadmap — Surge, Scourge, Verge, Purge, Splurge — is public and weird and being executed.
The competitor set has its own cultures. Solana's Anatoly Yakovenko shipped a single-state-machine, parallel-execution chain that traded validator decentralization for throughput; the network melted under load multiple times in 2022 and came back as the canonical home for memes, Pump.fun, and consumer apps. Sui and Aptos came out of Meta's Diem corpse with the Move language. Cosmos and the Tendermint stack pioneered app-chains and IBC. TON inherited Telegram's billion-user surface. NEAR pushed sharding and chain abstraction with Illia Polosukhin (who co-authored the Transformer paper, incidentally).
The argument that won't die is monolithic versus modular. Solana says one chain, one state, one execution environment. Ethereum says rollup-centric — settlement and DA on L1, execution on L2s. Cosmos says sovereign app-chains. The honest answer is that the question is empirical and the next decade decides it. What's settled: L1 design is a values question dressed up as an engineering one.
What Ethereum intends to provide is a blockchain with a built-in fully fledged Turing-complete programming language that can be used to create 'contracts' that can be used to encode arbitrary state transition functions, allowing users to create any of the systems described above, as well as many others that we have not yet imagined, simply by writing up the logic in a few lines of code.Ethereum whitepaper →
Every Layer 1 picks a fight. Ethereum optimizes for credible neutrality and validator decentralization at the cost of throughput. Solana optimizes for throughput at the cost of validator hardware requirements. Cosmos picks sovereignty per chain. Move chains pick a safer language. TON picks workchains and Telegram distribution. NEAR picks sharding done at the protocol level. The trade-offs are visible in the architecture if you read closely.
Ethereum runs the EVM, a stack-based virtual machine where every opcode has a deterministic gas cost. Vitalik Buterin's 2013 whitepaper, mainnet July 2015, Merge to proof-of-stake September 2022. Validators stake 32 ETH, get organized into committees, propose blocks in 12-second slots and finalize in 32-slot epochs. Roughly a million validators secure the network — the most decentralized validator set in production. The chain trades raw throughput for credible neutrality and an L2-centric scaling roadmap. The settlement layer everyone else builds against.
Anatoly Yakovenko's 2017 design unifies Proof of History — a verifiable delay function that timestamps the chain — with Tower BFT consensus and Sealevel parallel execution. Transactions declare which accounts they read and write, so the runtime executes non-conflicting ones in parallel across cores. 400ms slots, hardware that looks like a data-center node, and a willingness to halt and restart when things go wrong. Mainnet beta March 2020. Firedancer (Jump Crypto's independent client) is the second-implementation bet. Throughput at the cost of validator accessibility.
Cosmos is the appchain thesis given form. Tendermint (later CometBFT) provides instant-finality BFT consensus; the Cosmos SDK is a framework for building application-specific chains; IBC is the Inter-Blockchain Communication protocol that lets sovereign chains pass tokens and messages with cryptographic light-client verification. Jae Kwon and Ethan Buchman's 2014 whitepaper, mainnet 2019. Each chain has its own validator set and governance — sovereignty over shared security. Celestia, dYdX v4, Osmosis, Sei all live in this lineage.
Both chains descend from Meta's Diem project and ship the Move language, which treats digital assets as linear resources — they can't be copied or accidentally dropped, only moved between addresses. Aptos (Mo Shaikh, Avery Ching) launched October 2022; Sui (Mysten Labs, Evan Cheng) launched May 2023. Sui's object-centric model parallelizes by default; Aptos uses Block-STM optimistic execution. Move's type system makes whole classes of Solidity bugs unrepresentable. Different bets on parallelism, same conviction that languages should make smart contracts safer to write.
The Open Network started inside Telegram in 2018, was abandoned after the SEC blocked the ICO, then revived by the open-source community. Architecture is a masterchain plus dynamically sharded workchains — the network spawns new shards as load demands. Smart contracts live on shards; the masterchain coordinates. Native integration into Telegram's billion-user surface gives TON distribution no other L1 has. Notcoin and Hamster Kombat showed the funnel works. Different consensus assumptions and a different developer ergonomics from EVM land.
NEAR (Illia Polosukhin, Alex Skidanov) ships Nightshade, a sharding model where the chain is logically a single ledger but each block is produced as fragments — chunks — across shards. Validators are reshuffled across shards each epoch to prevent collusion. Account model uses human-readable names (alice.near) and meta-transactions for gas abstraction. Mainnet 2020. Recently pivoted hard into AI infrastructure with Polosukhin's Transformers-paper credentials and the AI-agent narrative. Sharding done at protocol layer, not punted to rollups.
Conviction is stated as conviction; you decide what to do with it. Tiers below — Core, Conviction, Watch, Speculative — reflect how much of FRQNCY's attention each project currently earns, not a recommendation to buy.
Conviction is theatre without practice. Five steps that turn the thesis above into something the body actually does, not just something the mind agrees with.
Holesky for Ethereum, Devnet for Solana. Feel slot times and finality in your own logs.
Ethereum, Solana, Cosmos. Notice the UX, the fees, the wait times. The differences are the thesis.
Gavin Wood's notation is dense. The state transition function is the whole game.

Ethereum All Core Devs, Solana validator calls. The roadmap is in the meeting notes, not the marketing.
The Crypto hub is the index of all sectors and the freedom-technology frame they share. The Fund is what happens when the same conviction gets put to work on behalf of the network.
