Ethereum Layer-2 solutions primary techniques: $STRK $METIS $MATIC
1. ZK Roll-ups:
- Utilizes zero-knowledge proofs to bundle multiple transactions into a single batch.
2. Validium:
- Similar to ZK Roll-ups but stores data off-chain to enhance scalability.
3. Optimistic Roll-ups:
- Assumes transactions are valid by default and uses fraud proofs for validation.
4. State Channels:
- Allows participants to transact off-chain, only recording the final state on-chain.
5. Plasma:
- Uses child chains to process transactions off-chain with periodic commitments to the main chain.
6. Sidechains:
- Independent blockchains running in parallel to the Ethereum main chain, connected via a two-way peg.
