• This reduces the cost of each individual operation

Optimistic Rollups

• Assume all transactions are valid

• Have a dispute period (usually 7 days)

• Anyone can prove fraud

• Used in Arbitrum and Optimism

ZK-Rollups

• Use mathematical proofs

• Each transaction is verified instantly

• No dispute period

• More technically complex

• Applied in Polygon
