Layer 1 & Layer 2 Blockchains
Layer 1 (Main chain)
They are an independent set of solutions for the base protocol and for the core system and the main architecture.
Layer 2
Secondary Blockchains that operate ON TOP of Layer 1 blockchains, to improve the Layer 1 efficiency.
↓
Layer 1 examples:
Ethereum
Bitcoin
Solana
Cosmos
Tron
Near
Polkadot
Avalanche
Tezos
Celo
Fantom
Algorand
Layer 2 Examples:
Zk Sync
Starknet
Polygon
Arbitrum
Optimism
Bitcoin's Lightning Network

🏁Conclusion
As you can see, each blockchain literally opens up a world, and the list is certainly incomplete.
It will be interesting to see if in the future the number of blockchains will increase or decrease, as it was for search engines in the '90s.
We will see.
I am posting one Web3 related content every day for 100 days.
Here is the GitHub repository with all the poss day by day.
I am at day 67 and the repository is close to 200 stars
