	Optimistic rollups sit in parallel to the main [[Ethereum]] chain on layer 2. They can offer improvements in scalability because they don't do any computation by default. Instead, after a transaction, they propose the new state to [[Mainnet]] or "notarise" the transaction.		Optimistic rollups sit in parallel to the main [[Ethereum]] chain on [[layer 2]]. They can offer improvements in scalability because they don't do any computation by default. Instead, after a transaction, they propose the new state to [[Mainnet]] or "notarise" the transaction.

	With Optimistic rollups, transactions are written to the main [[Ethereum]] chain as <code>calldata</code>, optimising them further by reducing the [[Gas fees\|gas]] cost.
