➡️ What are levels L0, L1, L2 and L3 #блокчейн and why are they needed? -- L2! (L0, L1, L3 will be on my profile soon)
ℹ️ Layer 2 (L2) blockchain is a type of blockchain technology designed to make existing L1 blockchains faster, cheaper and more efficient. The L2 blockchain processes transactions faster than the L1 blockchain and returns the results of the data processing to the L1 blockchain instead.
✔️ This is achieved using various solutions:
⏺ State Channels: Off-line transaction exchanges with the final result recorded in the main blockchain to prevent congestion
⏺ Nested Blockchains: Layer 2 blockchains operate above layer 1 blockchains, consisting of interconnected but independent blockchains. Transactions occur in Layer 2, while Layer 1 resolves disputes and defines the interaction architecture
⏺ Sidechains: A hybrid of nested blockchains and state channels capable of processing multiple transactions simultaneously
⏺ Rollups: Combining multiple transactions and processing them on the Layer 1 network
