Layers

Layer 0 | Layer 1 | Layer 2 | Layer 3
Layer 0: Internet of Blockchains. e.g. Polkadot, Avalanche, Cosmos
Layer 1: Blockchain implementation. e.g. Bitcoin, Ethereum, Cardano, Solana, Algorand, Tezos
Layer 2: Scaling layers. e.g. LN, Rollups
Layer 3: UI Layer or DApps. e.g. Curve, Uniswap, Opensea
