A Layer 2 scaling solution that assumes all transactions are valid and only runs computation if someone challenges a transaction.
A Layer 2 scaling solution that assumes all transactions are valid and only runs computation if someone challenges a transaction. The 'optimistic' part means it trusts that transactions are honest unless proven otherwise. Arbitrum and Optimism are the two biggest optimistic rollups on Ethereum.
A Layer 2 scaling solution that bundles many transactions together before posting them to the main chain.
A secondary network built on top of a Layer 1 to improve scalability.
A Layer 2 scaling solution that bundles transactions off-chain and uses zero-knowledge proofs to verify them on the main chain.
