Layer 2 scaling solutions improve blockchain efficiency. Optimistic Rollups and ZK-Rollups are popular solutions. Optimistic Rollups assume all transactions are valid, then verify them in batches. ZK-Rollups use zero-knowledge proofs to validate transactions. State Channels are another solution, allowing users to transact off-chain and settle on-chain. For example,
$ETH transactions can be processed on Layer 2, reducing congestion on the main chain. This can increase transaction capacity from 15 to 100 transactions per second. Layer 2 solutions are key to scaling blockchains like
$ETH and
$BTC . Blockchain scalability is at the forefront of development. blockchaininfrastructure
