Blockchains are transaction based state machines
Uses
- [FILL]
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
Scaling Solutions
Layer 1
- Consensus changes
- Sharding
- Changes in block size
Layer 2
- State channels
- Nested Blockchains
- Rollups
- Optimistic Rollups
- ZK Rollups
- Sidechains
- Plasma (e.g. OMG, Polygon MATIC)
- Validium
